Description
LAVAGE ~ANDPIECE
BACKGROUND OF THE INVENTION
The pri~sent invention gane~a:Lly relate6 to an irrlgatLon-suction I handpiece for 8elec~1vely applying an irrigaeing fluld ~o, ~nd wiithdrawing by¦
S I suction, unwanted fluid and debris from a surgical operatlng site.
I ~and-held irrigaeion ~uction dev~ces have long bee~ usied in surgLca~
¦l and dental procedures for variouP purposes at ~he operatLng siite or wound, to , facll~ate the cleaning and lavage of wounds.
~I Conventionally~ the irrigating and Bu~tion devices have been combinId 1~ a sLngle piece of isurgical equipment for convenlent hand use by the operatorO One such prior art device is descrlbed in U. S. Patent No. 4,299,221 to Earl Phlllips and Robert Insalaco. This prior art handpiece provides an lrrigation-sucti?o~ handpiece incl~ding a hand~?e containing lDngitudlnally j extendi~g, iside-by-s?de suc?tion and irrlgant passageways respectLv21y lS connectible to a source of subatmospherLc pressure and sn lrrigant fluid source.
An irrigan~ valve is actuable for alterllately openlng and blocki~g flow o~
! irrigant fluid from the i~ource thereof through the irrigant paSs~gewayo An i. , air pressure condult includes a ~hird passageway in the n3ndle and connectible ' to an air pressure 80urse whii~h iiSi not at a~mospheric pressure end not influenced by pressure changes in the sllctlon passageway. The third passag _l way has a portlo~ i~ the handle selectilvely operable by the hand of the I operator for effecting a change in the pressure wlthin the thlrd passageway.
The lrrigant valve has a control input coupled wleh ehe alr pressure conduit i and third passage~ay and responsive to fiuch change in alr pressure therein ' for shi~ing between i~s open and blocking 6~ates, to thereby control the flow i of irrigant fluid to the opera~ing site.
The ehird passage~ay eontains a control hole 38. Ano~her con~rol ' opening 45 is provided which vents ehe 8uction passageway to the atmospherP.
1 Tip suction and irrlgant flow rom the irrlgan~ tlp ean be provided ind:lvidually or slmultaneously. More particularly, wlth ~he handle held in , ~
ehe hand of the operator, the operator ~ay conveniently cover ~he hole 45 ~lth ! his thumb or finger. This eliminates the bleed of air through h~le 45 into suction pa~sageway such that the full suction9 generated ~e ehe handpiece by l~ a rem~te vacuum source, appears at the open forward e~d of suction tlp, fo~ ¦1 removing fluent materlals fro~ the operating s~te.
Alternatively, the operator's th~mb or flnger c~n be used to close 1l hole 38 (instead of or simultaneously wiLh its covering of hvle 45~. When ope~, ¦¦ the hole 38 ~cts 2S d relief for the thlrd passa~eway, t~e gas pressure condui~
1~ and the ~alve control inlet, tending ~o keep same at near a~mospheric pressuret ~' On the other hand, closing of hole 3~ causes the third passageway, the gas pressure co~dui~ and th~ valve control inlet to change pres~ure~ to the press~re 9f ~n air pressure source. This change in presBure ~e ~he control ! ~nlet opens the lrrigation valve producing a flow of irrlgant liquid from a sourc~ through the irrigant passageway and out the front end of ~he irrigant ~ tip to the operating si~e.
As long as the operator of this prior art device deslres irriga~ion and/or suctlon to be provided a~ ~he operative site, the opera~r's finger must keep the resp~ctive hole(s) covered. This restricts the hand position ' of the operator. ~ven with the suction hole ~ncovered, a little suction may , be present at the forward end of the suction tip. Also, the irrlgation valve ~dds unnece8~ary complesity to the device.
Another prlor art device is described in U. 5. Patent No. 3,993,054 to Gordo~ Newma~. This device relat~s to only a lavage or irrigating device.
The flow of liquld is either allowed or reRtricted by the manual control of a pi~ch val~e.

I housing vr body 113 ~hroueh which lrrlgation and suction tubes 115 and 11~ pass.
, 4_ ,, I
5~D I
I The bouslng 113 has a "pisto:L" conflguration ln which the housing 11 ¦ is formed with an angle sO that one portlon of the housing 113 is a p~stol gri~
portlon 119 which is connected with a for~ard facing portlon 121, analogou~ to I¦ a pistol's ~uz~le. This arrangement enables an operator of the handpiece 111 ¦ to easily grip ~nd direct the handpiece 111 ~hile e~erclsing convenient control ¦ ~f fluid flswing through the handpiece ~ith pinch valveh to be described later.
A pair of channels 122, 124 may be provided, channel 122 being an irrigatlon tube-receiving channel and channel 124 being a ~uctlon tube-receivi4gchannel. The sppropriate tubes pass through these channels. A slot 147 ln ¦¦ communlcates between the irrigation tube-receivlng channel 122 and the outslde !
¦ of the ho~sing 113 7 A trigger 151 h~ving tube-engaging end 153 and a finger grip 155 ls pivotably mounted ln slot 14~. The finBer grip 155 remains outside o~ the housing 113 60 that a person holding the handpi ce 111 at the ¦I pistol grip portion 119 with one hand may use a finger o~ that hand ~o use the !
,I flnger grip ~55 to nperate the trigger 1~1. The tube-engaging end 153 ls a ¦ cam-like pro;jectlon ~nd 1~ located within ~he housing 113. The ~rigger 151 ~s¦ pi~vtable ~o ~hat the tube~engaging end 153 may extend into and out of the ¦I channel 122. Thus, the finger grip 155 may be used to pivot the tube engagingI¦ end 153 into and ~ut of en8age~ent wlth an i~rigation tube 115 h~used by thP
¦1 irrigation channel 122.
i ! The housln~ 113 includes a fixed internal ridge ~o tha~ end 153 has I
¦ a rigid surf~ce for the trigger 151 eo slqueeze or wedge eh~ tube 115 agains~ tq ¦, close off the tubing 115. When separate elo6e fi ting channels 122 and 124 I¦ are provided for t~bl~g 115 and 117t respec~fully, this po~tion of the housing ¦ ~eparating the chan~els conveniently functions as an in~ernal rldge 195 for th~
~ubing ~o be held in pl2ce agalnst.
. When the tube-engagin~ end 153 i8 moved i~o engagement with ~he ~Irigatlon tube 115, the end 153 wedges the tube 115 agai~s~ ~he internal ridgq ! 153 call61n~ th~ inner dlameter ~o compress and elo6e ~ff~ Therefore, ~han ¦ the trigger 151 16 operated to extend lnto engagement with irrigation ~ube 115 thi6 causes the flow to be ~topped through the irrig~tion tube 115. The wedging action holds the end 153 in engage~ent against the tube llS without the ~id of externally spplied pressure. When the trigger 151 ls operated to pivot out of engag~nent ~ith the irrigation tube 115, the appropriate irrigatian flow iB free eo flow through the irrigatlon tube 1.15. The end of tube lli exeending fro~ the p1stol-~rip portion 119 ls co~neeted to an external irrigant liquid source, and the other end of the tube 115 provldes an outlet ~neans fvr the irrigant flu-Ld. Arrow l9S ~hows the dlrection of the fluid flow.
In Fig. 3, the tube-engaging end 153 is shown out of eng~gement wlth the irrlgatlon tube 115. The tube-engaging end 153 ~ay be positioned on the trlgger 151 as shown in Fig. 3 so th~ when the finger-grip 155 is pulled toward the pistql-grip portion 119, She tube-engaglng end 153 moves into engag~nent wlth the lrrigation tub~ 115 and sh~t6 off the flow of irrigaeion 1 through tube 115. The pi~tol-~rip pDrtlon 119 acts as g 6top ~eans for ! preventing f~Fther rotation of the triggler 151.
¦ Alternat~vely, the tube-engagimg end 153 may be positioned on the trigger 151 ~this position not ~hown~, 60 that when ~he ~inger-grip 155 is pulled toward the pistol-grip port~on 119, the tube~en~aging end 153 disengage~
li from the irrigation tube llS ~nd opens the irrigation tube 115 for flow. The ¦ fir6t mentioned optlon nay be referred to as the "pull-off" version, and the lat~e opeiOn ,as the ~pull~on" version. With the pull-on verAion9 ~not shown) l the tube-~ngaging end 153 would he located fureher clockw~se around the pivot Il of the trigger 151 (6ee Fig. 3 to establlsh the reference of the direceion i clockwise) ~o that when the finger-grlp portion 155 is positioned ~s shown in ll Fig. 3, the tube-engaging end 153 would be eng~ging and shuttl~g off the ¦! irrigaeion ~ube 115. To di3engage ~r open the irrigation tube l15, the "pull-~
Il onl' ~rigger would be pulled toward the piseol gr~p port~on 119. Slot 147 ¦I would néed t~ be widened in order tn allow the tube-eng~ging end 153 of the ! ¦ "pull-on" trl~ger to rot~te out o~ engagemene. Elther type of trigger 151 1¦ ~pull-off or p~ on) may be provided. SomP operator~ m~y prefer one type of I trl~ger ~ceion over ~he ~ther.

I, -6- 1 With regard to the control of ~he suctlon function of the handpiece, ¦
~ pinch valve 157 is m~unted wlthln a pinch valve opening 159, wlth the pinch !
valve opening extendlng from the outside 3f the housing 113 aDd interrupting . the suction tube-receiving channel 124. Plnch valve 157 take6 the ~orm of a S biased cllp which is bias~d in the opened position. The pinch valve 157includes a serrRted arm 161 and a means for engaging the serrations. In order to close ehe suction tube 117, the means for engaging th ~erratlons i8 depressed to c2use a protrusion means on the valve 157 to co~press or clamp off the opening ln the tube 117. The ~ixed i~ternal ~idge 195 may also act to support the pinch valYe 157 as ehe ~eans for engaging the serrations is depressed. The aerrated a~ 161 holds the pl~ch val~e 157 in a closed or par~ially closed position, as set by ~he operator un~ he ~errated arm 161 i~
deflected, the~eby releasing a~d opening pinch valve 157. When the suction tube 117 1~ open or o~ly partially closed~ suctlon may be provided through the ¦ ~uction tube 11~ from a ~uct~on source ~hich is remote f~om ~he h~ndpiece. Th~end of ehe 6uction tube 117 extending from the pistol-grip portion 119 is con-~ected to the external suction sour e~ a~d the other end of the e~be 117 pro~
des an inlet means for the flow of suction. Arrow 198 ~hows the di.re~tion o~
1 ehe suction flow.
~ Pinch valve 157 is located so that an oper~tor may control both j, plnch valve 1~7 and ~rigger 151 slmultaneously, probably usi~g the thumb to - ,~ oontrol pl~ch ~alve 157 ~nd the forefinger of the hand grlpping the pistol il grlp portion 119 to control the trigger 151.
~', Ya~ous nozzle tips, such as lrrigation suction no7zle tip 193 may 1I be selecelvely attached to the handpiece. A nozzle adapeor 191 may be provided WhiCh a~t~ches on ~e sld2 to the s~ction and irsig~ion ~ubing 117 . ¦ ~nd 115, re~pectively. The other side of the adaptor~ attach to the ~arious nozzle ~ip8. The nozzle ~ip6 may be fric~ion fit to the adapeor 191. O~her li ~echanlcal ~eans may be u~illzed if a more secure attach~ent ~3 desired. The i 1 adaptor 191 may be flxedly secllred to ~he houslng 113, lf deslrable. The i , , 7 j separat~ly attachable nozzles perQlt the operator of the hPndp{ece to select ¦ the type of nozzles to be used. This e1~ables the selection of dlfferellt ¦ nozzle tips ~d permits the changing of nozzle tips durl~g a surgical l procedure without re~uiring th~t the entire handpiece be changed. The provlsion o ~everal eips provides a large aelection of outputs, ~hile ellmi~aeing a requirement that different types of l~ndpiece~, be seored for different nozzle functions. The nozzles al,~,o may be disposeble.
Combination lrrigation a~d suction tips, ,~,uch as irrigation noz~le Il tip 193 m~y be used. These combl~ation tlps provide a fixed relationship ¦I between ~he posltiGns of the irrigatlon and suction nozzles. Separately Il attachable lrrigaelon and suctlon tips ~ay also be provided.
,I The hou61ng 113 of the handplece may be manufactured ln two halves.
The halves may be mechanically fi~ed together by screws or securing clips or othe~ c~n~enient means. The handpiece is readlly assembled with both the 'I suction and i~Figation tubes i~te~,ally fitted ineo ~he housing so ~hat irrigatio~ and suctlon ~re conveniently controlled by pi~ch valves. The separate halve~ c~nvenien~ly allo~ the tubing 115 ~nd 117 ~d tri8ger 151 and pinch valve 157 ~o be easlly inserted ln the housing 113 before securing the ''! halves together. This feature also enables the handpiece to be reopened to 1 replace the ~ubing or ~he trigger 151, if necessary. This enable~ hP tubing , to be disposa~leO It al~o enables the trigger 151 to be ~witched fr~m pull-off to ~ pull on seyle or Yice vers , lf desirable. Alternatlvely, ~he total ha~dpiece, i~cluding the tubing may be d~sposable. This configuration ,1 al~o min~mlzes a~s~mbly costs.
¦' For the totally disposable handpiece~ the housing 113 may be easily ~olded from a~y sui sble plastic material. Th~ trigger 151, the pinch valve 157, the adap~or 1~1, and the ~arious nozzles may also be made ~f a suitable plastic ~aterial. Other ~aterials ~han plastlc may be u~ed, if desired. If I! the handpiece hounlng 113 is to be reuseable, i~ may be morP sui~ably 1l manufactured from a metal ~aeerial~ The ~ubing 115 ~nd 117 also may be any l~ suitable ~aterial capable of belng clamped off, such a5 PVC or 6ilicone tubing.

5~ l ll Ref~rring to FigP. 4-9, a~ alternete embodiment of a lavage ¦¦ handpiece 1~ shown. The handpiece 11 comprises a housing 13 throu~sh wh~ch ¦' an irrigation tube 15 passes. A ~ctlon tube 17 1R mounted e~t rnally of Ij the housing 13. The housing 13 has a pistol conflguratio~ such as the 1l previou~ly described housing 113. The housing 13 i8 formed wlth ~n angle j 80 that one portion of the houslng is a pistol grip portio~ 19 which is ¦¦ connected with a forwa~d facing portlon 21. Again, this arrangement enables ¦ an oper~tor of the handpiece 11 to easily grlp and d~rect the handpiece 11 ~ whlle exeroising control of fluid flowing through the handp~ece ~ith pin~h ¦¦ valv~s.
The housing may be manufactured in two half 6ections, Ehe left half sectlon 23 a~d the right half sectlon 25 as seen iLn Fig. 9. The half sections 23, 25 ~ay be llnked by a flexible strip 27 cr hin~e portion. In the~
li e~bodiment ~hown, the flexible strip 27 is; lntegrally ~olded ~ith ~he left and !I riLght half se~tions 23, 25. The hlnge pcrtion 27 enables the half sections to pivot about a hinge line 35 as shown iLn Fig. 9.
WhiLle an integral fl~$ble hin~se 27 i~ shown, it is anticipated that other ~eparably attached hinge ~eans: would be suitable, lf a hlnge , portion 27 i~ deslrable between the half section~ 23, 25. Referring to ll Fig 8 and 9~ the half sections 23, 25 fall together about the hinge llne 35 so tha~ the half ~ectio~s 23, 25 mate at an interface surface 37.
Fi~s. 4-6 and 8 illustrste a suitable means for holdlng the half ~ections 23, 25 together. A slo~ted sleeve 61 -ls slidably ~ounted to thP righ~
¦I half section 25 on the forward facing portion 21.

BACKGROUND OF THE INVENTION
The pri~sent invention gane~a:Lly relate6 to an irrlgatLon-suction I handpiece for 8elec~1vely applying an irrigaeing fluld ~o, ~nd wiithdrawing by¦
S I suction, unwanted fluid and debris from a surgical operatlng site.
I ~and-held irrigaeion ~uction dev~ces have long bee~ usied in surgLca~
¦l and dental procedures for variouP purposes at ~he operatLng siite or wound, to , facll~ate the cleaning and lavage of wounds.
~I Conventionally~ the irrigating and Bu~tion devices have been combinId 1~ a sLngle piece of isurgical equipment for convenlent hand use by the operatorO One such prior art device is descrlbed in U. S. Patent No. 4,299,221 to Earl Phlllips and Robert Insalaco. This prior art handpiece provides an lrrigation-sucti?o~ handpiece incl~ding a hand~?e containing lDngitudlnally j extendi~g, iside-by-s?de suc?tion and irrlgant passageways respectLv21y lS connectible to a source of subatmospherLc pressure and sn lrrigant fluid source.
An irrigan~ valve is actuable for alterllately openlng and blocki~g flow o~
! irrigant fluid from the i~ource thereof through the irrigant paSs~gewayo An i. , air pressure condult includes a ~hird passageway in the n3ndle and connectible ' to an air pressure 80urse whii~h iiSi not at a~mospheric pressure end not influenced by pressure changes in the sllctlon passageway. The third passag _l way has a portlo~ i~ the handle selectilvely operable by the hand of the I operator for effecting a change in the pressure wlthin the thlrd passageway.
The lrrigant valve has a control input coupled wleh ehe alr pressure conduit i and third passage~ay and responsive to fiuch change in alr pressure therein ' for shi~ing between i~s open and blocking 6~ates, to thereby control the flow i of irrigant fluid to the opera~ing site.
The ehird passage~ay eontains a control hole 38. Ano~her con~rol ' opening 45 is provided which vents ehe 8uction passageway to the atmospherP.
1 Tip suction and irrlgant flow rom the irrlgan~ tlp ean be provided ind:lvidually or slmultaneously. More particularly, wlth ~he handle held in , ~
ehe hand of the operator, the operator ~ay conveniently cover ~he hole 45 ~lth ! his thumb or finger. This eliminates the bleed of air through h~le 45 into suction pa~sageway such that the full suction9 generated ~e ehe handpiece by l~ a rem~te vacuum source, appears at the open forward e~d of suction tlp, fo~ ¦1 removing fluent materlals fro~ the operating s~te.
Alternatively, the operator's th~mb or flnger c~n be used to close 1l hole 38 (instead of or simultaneously wiLh its covering of hvle 45~. When ope~, ¦¦ the hole 38 ~cts 2S d relief for the thlrd passa~eway, t~e gas pressure condui~
1~ and the ~alve control inlet, tending ~o keep same at near a~mospheric pressuret ~' On the other hand, closing of hole 3~ causes the third passageway, the gas pressure co~dui~ and th~ valve control inlet to change pres~ure~ to the press~re 9f ~n air pressure source. This change in presBure ~e ~he control ! ~nlet opens the lrrigation valve producing a flow of irrlgant liquid from a sourc~ through the irrigant passageway and out the front end of ~he irrigant ~ tip to the operating si~e.
As long as the operator of this prior art device deslres irriga~ion and/or suctlon to be provided a~ ~he operative site, the opera~r's finger must keep the resp~ctive hole(s) covered. This restricts the hand position ' of the operator. ~ven with the suction hole ~ncovered, a little suction may , be present at the forward end of the suction tip. Also, the irrlgation valve ~dds unnece8~ary complesity to the device.
Another prlor art device is described in U. 5. Patent No. 3,993,054 to Gordo~ Newma~. This device relat~s to only a lavage or irrigating device.
The flow of liquld is either allowed or reRtricted by the manual control of a pi~ch val~e.

I The bouslng 113 has a "pisto:L" conflguration ln which the housing 11 ¦ is formed with an angle sO that one portlon of the housing 113 is a p~stol gri~
portlon 119 which is connected with a for~ard facing portlon 121, analogou~ to I¦ a pistol's ~uz~le. This arrangement enables an operator of the handpiece 111 ¦ to easily grip ~nd direct the handpiece 111 ~hile e~erclsing convenient control ¦ ~f fluid flswing through the handpiece ~ith pinch valveh to be described later.
A pair of channels 122, 124 may be provided, channel 122 being an irrigatlon tube-receiving channel and channel 124 being a ~uctlon tube-receivi4gchannel. The sppropriate tubes pass through these channels. A slot 147 ln ¦¦ communlcates between the irrigation tube-receivlng channel 122 and the outslde !
¦ of the ho~sing 113 7 A trigger 151 h~ving tube-engaging end 153 and a finger grip 155 ls pivotably mounted ln slot 14~. The finBer grip 155 remains outside o~ the housing 113 60 that a person holding the handpi ce 111 at the ¦I pistol grip portion 119 with one hand may use a finger o~ that hand ~o use the !
,I flnger grip ~55 to nperate the trigger 1~1. The tube-engaging end 153 ls a ¦ cam-like pro;jectlon ~nd 1~ located within ~he housing 113. The ~rigger 151 ~s¦ pi~vtable ~o ~hat the tube~engaging end 153 may extend into and out of the ¦I channel 122. Thus, the finger grip 155 may be used to pivot the tube engagingI¦ end 153 into and ~ut of en8age~ent wlth an i~rigation tube 115 h~used by thP
¦1 irrigation channel 122.
i ! The housln~ 113 includes a fixed internal ridge ~o tha~ end 153 has I
¦ a rigid surf~ce for the trigger 151 eo slqueeze or wedge eh~ tube 115 agains~ tq ¦, close off the tubing 115. When separate elo6e fi ting channels 122 and 124 I¦ are provided for t~bl~g 115 and 117t respec~fully, this po~tion of the housing ¦ ~eparating the chan~els conveniently functions as an in~ernal rldge 195 for th~
~ubing ~o be held in pl2ce agalnst.
. When the tube-engagin~ end 153 i8 moved i~o engagement with ~he ~Irigatlon tube 115, the end 153 wedges the tube 115 agai~s~ ~he internal ridgq ! 153 call61n~ th~ inner dlameter ~o compress and elo6e ~ff~ Therefore, ~han ¦ the trigger 151 16 operated to extend lnto engagement with irrigation ~ube 115 thi6 causes the flow to be ~topped through the irrig~tion tube 115. The wedging action holds the end 153 in engage~ent against the tube llS without the ~id of externally spplied pressure. When the trigger 151 ls operated to pivot out of engag~nent ~ith the irrigation tube 115, the appropriate irrigatian flow iB free eo flow through the irrigatlon tube 1.15. The end of tube lli exeending fro~ the p1stol-~rip portion 119 ls co~neeted to an external irrigant liquid source, and the other end of the tube 115 provldes an outlet ~neans fvr the irrigant flu-Ld. Arrow l9S ~hows the dlrection of the fluid flow.
In Fig. 3, the tube-engaging end 153 is shown out of eng~gement wlth the irrlgatlon tube 115. The tube-engaging end 153 ~ay be positioned on the trlgger 151 as shown in Fig. 3 so th~ when the finger-grip 155 is pulled toward the pistql-grip portion 119, She tube-engaglng end 153 moves into engag~nent wlth the lrrigation tub~ 115 and sh~t6 off the flow of irrigaeion 1 through tube 115. The pi~tol-~rip pDrtlon 119 acts as g 6top ~eans for ! preventing f~Fther rotation of the triggler 151.
¦ Alternat~vely, the tube-engagimg end 153 may be positioned on the trigger 151 ~this position not ~hown~, 60 that when ~he ~inger-grip 155 is pulled toward the pistol-grip port~on 119, the tube~en~aging end 153 disengage~
li from the irrigation tube llS ~nd opens the irrigation tube 115 for flow. The ¦ fir6t mentioned optlon nay be referred to as the "pull-off" version, and the lat~e opeiOn ,as the ~pull~on" version. With the pull-on verAion9 ~not shown) l the tube-~ngaging end 153 would he located fureher clockw~se around the pivot Il of the trigger 151 (6ee Fig. 3 to establlsh the reference of the direceion i clockwise) ~o that when the finger-grlp portion 155 is positioned ~s shown in ll Fig. 3, the tube-engaging end 153 would be eng~ging and shuttl~g off the ¦! irrigaeion ~ube 115. To di3engage ~r open the irrigation tube l15, the "pull-~
Il onl' ~rigger would be pulled toward the piseol gr~p port~on 119. Slot 147 ¦I would néed t~ be widened in order tn allow the tube-eng~ging end 153 of the ! ¦ "pull-on" trl~ger to rot~te out o~ engagemene. Elther type of trigger 151 1¦ ~pull-off or p~ on) may be provided. SomP operator~ m~y prefer one type of I trl~ger ~ceion over ~he ~ther.

I, -6- 1 With regard to the control of ~he suctlon function of the handpiece, ¦
~ pinch valve 157 is m~unted wlthln a pinch valve opening 159, wlth the pinch !
valve opening extendlng from the outside 3f the housing 113 aDd interrupting . the suction tube-receiving channel 124. Plnch valve 157 take6 the ~orm of a S biased cllp which is bias~d in the opened position. The pinch valve 157includes a serrRted arm 161 and a means for engaging the serrations. In order to close ehe suction tube 117, the means for engaging th ~erratlons i8 depressed to c2use a protrusion means on the valve 157 to co~press or clamp off the opening ln the tube 117. The ~ixed i~ternal ~idge 195 may also act to support the pinch valYe 157 as ehe ~eans for engaging the serrations is depressed. The aerrated a~ 161 holds the pl~ch val~e 157 in a closed or par~ially closed position, as set by ~he operator un~ he ~errated arm 161 i~
deflected, the~eby releasing a~d opening pinch valve 157. When the suction tube 117 1~ open or o~ly partially closed~ suctlon may be provided through the ¦ ~uction tube 11~ from a ~uct~on source ~hich is remote f~om ~he h~ndpiece. Th~end of ehe 6uction tube 117 extending from the pistol-grip portion 119 is con-~ected to the external suction sour e~ a~d the other end of the e~be 117 pro~
des an inlet means for the flow of suction. Arrow 198 ~hows the di.re~tion o~
1 ehe suction flow.
~ Pinch valve 157 is located so that an oper~tor may control both j, plnch valve 1~7 and ~rigger 151 slmultaneously, probably usi~g the thumb to - ,~ oontrol pl~ch ~alve 157 ~nd the forefinger of the hand grlpping the pistol il grlp portion 119 to control the trigger 151.
~', Ya~ous nozzle tips, such as lrrigation suction no7zle tip 193 may 1I be selecelvely attached to the handpiece. A nozzle adapeor 191 may be provided WhiCh a~t~ches on ~e sld2 to the s~ction and irsig~ion ~ubing 117 . ¦ ~nd 115, re~pectively. The other side of the adaptor~ attach to the ~arious nozzle ~ip8. The nozzle ~ip6 may be fric~ion fit to the adapeor 191. O~her li ~echanlcal ~eans may be u~illzed if a more secure attach~ent ~3 desired. The i 1 adaptor 191 may be flxedly secllred to ~he houslng 113, lf deslrable. The i , , 7 j separat~ly attachable nozzles perQlt the operator of the hPndp{ece to select ¦ the type of nozzles to be used. This e1~ables the selection of dlfferellt ¦ nozzle tips ~d permits the changing of nozzle tips durl~g a surgical l procedure without re~uiring th~t the entire handpiece be changed. The provlsion o ~everal eips provides a large aelection of outputs, ~hile ellmi~aeing a requirement that different types of l~ndpiece~, be seored for different nozzle functions. The nozzles al,~,o may be disposeble.
Combination lrrigation a~d suction tips, ,~,uch as irrigation noz~le Il tip 193 m~y be used. These combl~ation tlps provide a fixed relationship ¦I between ~he posltiGns of the irrigatlon and suction nozzles. Separately Il attachable lrrigaelon and suctlon tips ~ay also be provided.
,I The hou61ng 113 of the handplece may be manufactured ln two halves.
The halves may be mechanically fi~ed together by screws or securing clips or othe~ c~n~enient means. The handpiece is readlly assembled with both the 'I suction and i~Figation tubes i~te~,ally fitted ineo ~he housing so ~hat irrigatio~ and suctlon ~re conveniently controlled by pi~ch valves. The separate halve~ c~nvenien~ly allo~ the tubing 115 ~nd 117 ~d tri8ger 151 and pinch valve 157 ~o be easlly inserted ln the housing 113 before securing the ''! halves together. This feature also enables the handpiece to be reopened to 1 replace the ~ubing or ~he trigger 151, if necessary. This enable~ hP tubing , to be disposa~leO It al~o enables the trigger 151 to be ~witched fr~m pull-off to ~ pull on seyle or Yice vers , lf desirable. Alternatlvely, ~he total ha~dpiece, i~cluding the tubing may be d~sposable. This configuration ,1 al~o min~mlzes a~s~mbly costs.
¦' For the totally disposable handpiece~ the housing 113 may be easily ~olded from a~y sui sble plastic material. Th~ trigger 151, the pinch valve 157, the adap~or 1~1, and the ~arious nozzles may also be made ~f a suitable plastic ~aterial. Other ~aterials ~han plastlc may be u~ed, if desired. If I! the handpiece hounlng 113 is to be reuseable, i~ may be morP sui~ably 1l manufactured from a metal ~aeerial~ The ~ubing 115 ~nd 117 also may be any l~ suitable ~aterial capable of belng clamped off, such a5 PVC or 6ilicone tubing.

5~ l ll Ref~rring to FigP. 4-9, a~ alternete embodiment of a lavage ¦¦ handpiece 1~ shown. The handpiece 11 comprises a housing 13 throu~sh wh~ch ¦' an irrigation tube 15 passes. A ~ctlon tube 17 1R mounted e~t rnally of Ij the housing 13. The housing 13 has a pistol conflguratio~ such as the 1l previou~ly described housing 113. The housing 13 i8 formed wlth ~n angle j 80 that one portion of the houslng is a pistol grip portio~ 19 which is ¦¦ connected with a forwa~d facing portlon 21. Again, this arrangement enables ¦ an oper~tor of the handpiece 11 to easily grlp and d~rect the handpiece 11 ~ whlle exeroising control of fluid flowing through the handp~ece ~ith pin~h ¦¦ valv~s.
The housing may be manufactured in two half 6ections, Ehe left half sectlon 23 a~d the right half sectlon 25 as seen iLn Fig. 9. The half sections 23, 25 ~ay be llnked by a flexible strip 27 cr hin~e portion. In the~
li e~bodiment ~hown, the flexible strip 27 is; lntegrally ~olded ~ith ~he left and !I riLght half se~tions 23, 25. The hlnge pcrtion 27 enables the half sections to pivot about a hinge line 35 as shown iLn Fig. 9.
WhiLle an integral fl~$ble hin~se 27 i~ shown, it is anticipated that other ~eparably attached hinge ~eans: would be suitable, lf a hlnge , portion 27 i~ deslrable between the half section~ 23, 25. Referring to ll Fig 8 and 9~ the half sections 23, 25 fall together about the hinge llne 35 so tha~ the half ~ectio~s 23, 25 mate at an interface surface 37.
Fi~s. 4-6 and 8 illustrste a suitable means for holdlng the half ~ections 23, 25 together. A slo~ted sleeve 61 -ls slidably ~ounted to thP righ~
¦I half section 25 on the forward facing portion 21. If the sleevP is slid forward jl alonK its mount, the left half sect~on may he closed against ~he rlght half ¦ eection by p~s~ing ~hrough a side opening 63 ln ehe slotted Rleeva 61. By sll~-¦¦ ing the ~lotted ~leev~ toward the rear portion of ~he half sec~lDns, the sleevq 6l completely encircles a por~lon of both half sections 23, ?5 ~h~s cooperatin~
I with the fle~ible hlnge 27 to lock the half sectlons 23~ ~5 ln the closed posi 1l tion. Oeher ~ult~ble me~ns for holding the half sections together may be used.
!
l~ The grooves 43, 45 may be provlded ~ieh ~nl~rged ends 65, 67. One o~
¦I the enlarged ~nds 65 is located Rt ~he forward facing portlon 21 and the other enlarged end 67 is located at the pistol grip pnrtlon 19. The enlarged ends I 65, 67 rooperate wlth enlarged portions 69, 71 on the irrlgatlsn tubing 15 to S ll prevent the irrlgation tube 15 from sliding along the grovvesi 43, 45. Enlarge~
¦I portlon 69 i5 a tubular flange attached to the tubing 15. ~he flange 69 is il locsted at enlarged end 65 and has a eip-~ounting extenslon 73 located thereon ¦¦ The tip mountlng extension 73 extends out of the molded b~dy 13 and fo~ms a l~ suRport for mounting interchangeable tips, such as the irrigaelon tip 75, to 1 com~un~cate with irrigation tube 15.
As sihown ln Fig. 8, the irrigation tube 15 ls s~p~raeed into a handpiece portion 79 (of the irrigation t~be 15) and a main portion 81 Sof the irrigation tube 15). The main portion 81 leads to the remcte irrigation 1 ~ource. The sieparate main por~ion 81 enables thls main portion to be detachedfrom ~he hsndpiece.
