i'Be it known that we, URI GQ Barnsv and JEROME McLnLA-ND, citizens of` the United States, residing at Seattle, in thecountyof yKing and- State ofy Washington, have invented certain new and useful'lniprovements in Surgical Apparatus, of which thevfollowging is a specification.
Thisinvention relates to surgical apparatus'and particularly to devices for retracting the sides 0f anincision inthe abdominal walls to enable the surgeonlto work upon the deeper tissues.
One'of the objects of ythe invention is the lprovision ofv novelzretractile means whereby the'opera'tor may adjustably'retain the sides ofy an incision in suitably'openfcondition.
Another object ofthe invention is thev pro-V vision Vof rvertically adjustable elementsk associated with said retractile means whereby, whenv retracted and first .engaged,'the abdominal walls may be raised to assist the ,insertion of packing gauze to keep the operating field clear of intestines. f A still further objectof the invention is the provision ofy an elastic lining for the opening made by thev operatorwhereby the edges of the incision are protected rfrom infection and a heinostatic effect produced whichA avoids a large element of danger `due from hemorrhage. i
The'invention consists in the novel con- A struction ofthe mechanical retractor devices and their. combination, together 'with the adaptation therewithof said elastic lining, which will'be fullvv described in' the following specification, illustrated in the accompanying drawings, an d finally :set forth in the appended claims.
In said drawings, view of apparatus embodying our invention. Fig, 2 is a longitudinal vertical sectional view of thesame. `Fig. Sisa curved sectional view through-'S-S of'Fi'g. 1.1 Figa is a detail detached perspective view of one,
of the retractile elements. Fig'. 5 is at simi.-

section. The opposite'inner and outer edgesof the frame have apertured up-turned integral lugs Qarranged in pairs to afford supv l, bar 3 engages the upper side of saidframestrip, and isy formed with a plurality of ratchet-notches i 5. formed with an arcuate slot 6 subjacent said retained` bar and spaced from-said slot at one end is an aperture 7.l A bent spring 8 Said kframe-strip is is secured at one end in said aperturean'd is extended symmetrically with said frame into said slot pressing resiliently upward upon said bar 8 and thence extends by an upward bend 9 above the frame and beyond" said slot. A tooth 10 extends from the upper face of said spring and engages with vsaid ratchet notches 5 ofthe bar and secures the retractorrin predetermined retractedposi-V tion. To advance the retractors, the end9 of the spring 8 is depressed to disengage the tooth 10 from said notches. rlhe inner end of said retractors comprises a shield 11 arv ranged at right angles to said bars and hav-P f ing a curvature substantially corresponding to that ofthe adjacent portion of the frame.l
As indicated in Fig. 1 the shields 111 ,of said retractors in alinement with the major axis of the frame maybe of less width than those laterally adjacent.V The lateral vertical edges cf each said shield are formed to provide guideways 12 for the slidable reception of an extension-plate V13.
with engaging devices upon said extension.
Referring to Fig. 2, said extension is seen to Said shieldl isgfurther provided with ratchet notches la on its inner concave face adaptedto ycoactv guideways 12 and a horizontally extending integral ledgeY or foot 16 along its bottom edge. Said plate 13is vertically vslotted to afforda spring-tongue 17'v formed with a tooth 15 adapted to engage in said notches 11i and retaining the extension in adjusted vertical positions. In Fig. 5 is shown a` modied form of said extension plate.
A lining 18 of elastic material, preferably rubber-,is provided to complete the appara'- y 'in F ig.. 6, to obtain greaterelasticity, and
tus comprising a diaphragm 19 of similar' superficial configuration as lsaid frame and of somewhat larger dimensions in thehorizontal plane. An elongated opening-2Q is p formed in its middle portion with-its lengthV in alinement with the major axis of vthe frame. ,The material of said lining iseXtended downwardly integrally .froml the diaphragm to form an elongated-tubular neck 21, Awhich may be verticallyribbed, as shown terminates at its v.bottoni edge lin an out-v wardlyrdirected fold 22l furnishing: a con-v tinuous internally opening crease 23Q'for the rreception of. the respective extension-feet 16."
A'fcircular hole 24risfformed near the outer extremity of each said bar 3 to aiord a seat for a pin 25 upon one end ofa springfmetal bow-clip 26 which straddles each'said bari extremity. Said'clip is further' vprovided with a projection 27 upon its opposite .end
l adapted to protrude within, the underside of.
said hole andyieldingly pinch the peiiph lso ' tions of'said retractors therein while the lateraledge of the diaphragm 19-and securethe .same in plane ycondition by slight tension.
vThe apparatus is assembled by engaging the retractors with the frame, vas described,V and adjusting the lining l8therewith so that the diaphragm 19 will underlie theframe strip and said bars 3 of the retractors whiletlie shields 11 are extended Vdo W-nwardly within the tubular neck 21l and the foot 16 of.l each extension-plate thereof is entered said crease 23, as clearly-V shownin Fig.2.
VUpon making anincision `in the abdominal wall of a patient, the surgeon introduces the neck 21 andthe contained dependent p'orter are in their advanced positionsand the jneck under slight,- if any, tension. vThe inajor aXis of said frame will be, of course, 1n
alinement with the length of thelincision.v The extension plates 13 may thenbe de' pressed to `extend below the abdominal wall' Y wherebythe severallayers of saidrwall, in-
cluding skin, fascia,muscle and peritoneuin, Vare included between the rubber-incased foot V16,'and thelining diaphragm. Theseve'ral retractors are then slidably movedv inl outvward directions against thepressure of thef elastic lining, stretching the edges of the incision to any suitable degree to Vobtain the necessary openingfor convenient work withy in the abdominal cavity.l Before the `operatorfproceeds with his work it inaygbedesir.- able to closelyengage the lower extending fold 22 of the neck 21 with theunder portion oftheperitoneal surface Vofthe'abdominalcavity tofully isolate the yinarg'fins of the woundv from any source of infection.,v This is accomplished'by the operator extending" his lingers beneath the respective feet 16 and pressing the plate 13 upwardwhere itis Vretained by the laterally eXtendingratchet-devices, thus closely-associating the portion of the tubular neck 21 with the peritoneuinand allowing space for the insertionof packing .gauzer to insure a-clear operating iield. Y
Of `the advantagesrresulting from the use of; our apparatus, we particularly Vindicate its'functions as an abdominal incision lor wounderetractor wherein the'incision'is distended to enable the surgeon to workv upon the-deeper tissues.1 Again, as a 'wound proA tector the elastic lining: is employdto `C O'Yel" the edges of the lincision yincluding-thevarious layers. (5f-which the abdominal wall is' composedkrfromV contact'with infective mat ter from without o'r within, thus keeping the f wound aseptic;"and lastly l as 'a-lhemostatic,
-s where, byfmeans ofpressure on' the sidesofthe Vincision exerted through the Vrubber orV l other material by the retrarztors, the VVhemorrhage :is controlled, thus, saving thetinie'of 4 V,and the leaking oftheblood into Ythe abdoIni-; Y Y y nal cavitv where itfinay dodamage tolthe the surgeon andpreventingtheloss of blood patientsv Y *Y f.
