ABSTRACT
An end effector for efficiently removing the gaseous byproducts of laser surgery from a surgical site is provided.
The end effector includes a flexible hose and a pliable vacuum head adhesively attachable in airtight relationship around a surgical site. The vacuum head includes a generally annular plenum for drawing plumes away from the surgical site from around a 360° arc. A porous plenum support prevents the flexible plenum from collapsing in the presence of a vacuum, and diffuses the vacuum around the entire periphery of the plenum.
Description
~ 1302826 1 Technical Field .
This invention relates to equipment for the removal of the gaseous byproducts of laser surgery. In particular, it relates to an end effector for a vacuum filtration system that efficiently removes smoke plumes produced through the use of lasers at a surgical site.
Background Art The use of lasers in surgical operations has become commonplace. An unwanted byproduct of laser surgery, however, is the smoke generated by interaction of the laser with skin and muscle tissues. Smoke plumes so caused can obscure the surgeon's field of vision, and the odor generated is unpleasant and distracting to the entire surgical team. Moreover, the smoke plume may contain infectious agents that present an immediate danger to persons in the operating room, and which can leave a lingering contamination within the operating area.
Evacuation filtering systems have been developed to remove smoke plumes from laser surgical sites. Such systems typically include a hose connected to a vacuum generator. Various 20 filtration systems have been used in conjunction with such vacuum generators to remove odor and infectious agents. Heretofore, the hoses of plume evacuation and filtration systems have required the constant attention of an attendant to hold the nozzle of the hose close to the surgical site. Moreover, the flow of 25 air through the hose nozzle is a source of excessive and unwanted noise in the operating room.
An end effector for a surgical plume evacuator that could be held in place at a surgical site without the constant attention of a nurse or other attendant, and which could efficient-30 ly, completely, and quietly remove smoke plumes from the areaof the surgical site, would be a decided advantage.
` ~3028~6 Summary of the Invent_on 1 The problems outlined above are in large measure solved by the surgical plume evacuator end effector in accordance with the present invention. The end effector hereof can be maintained at a laser sllrgery site without constant manipulation by an attendant, and is especially designed to completely, efficiently, and quietly remove the smoke plumes generated in the process of laser surgery.
The plume evacuator end effector hereof broadly includes an evacuation hose adapted for detachable connection to a vacuum generator having an environmental filter, and a vacuum head that completely surrounds a surgical site. The vacuum head is made of a pliable material and defines an evacuation plenum. A porous plenum supporting material is carried within the plenum to provide rigidity to the plenum and to prevent the plenum from collapsing when subjected to a vacuum. An adhesive layer is carried by the bottom wall of the vacuum head for maintaining the head in place at a surgical site.
Accordingly, in one aspect the invention resides in providing an apparatus for removing smoke, airborne particulates gaseous or like by-products of operating procedures producing such by-products from a surgical or other site, comprising a plenum having a top wall, a bottom wall spaced apart from said top wall, a side wall extending between said top and bottom walls and presenting an outer periphery of said plenum, and structure defining a generally open facing presenting an inner periphery of said plenum, said top, bottom, and side walls defining an ~ r~
æ~
1 internal plenum chamber in fluid communication with said open facing; vacuum means operably coupled to said plenum for creating a reAuced pressure within said plenum chamber thereby drawing said by-products through said open facing;
and diffuser means carried within said plenum chamber for maintaining said top and bottom walls in spaced apart relationship and distributing said reduced pressure along the inner periphery of said plenum whereby said by-products are drawn through said open facing from spaced points about said site.

Fig. 4 is a side elevational view of the end effector vacuum head; and Fig. 5 is a perspective view of a second embodiment of an end effector in accordance with the present invention.
- 2a -l302a26 1 Detailed Description of the Drawings Referring to the drawings, a plume evacuation system 10 having an end effector 12 in accordance with the present invention is depicted in Fig. 1. The end effector 12 is shown detachably connected to a vacuum generator and filtration asse-_:y 14. The vacuum/filtration syste~ typically includes a vacuum generator motor and an environme~tal filter (both not shown).
Air is cycled into the vacuum senerator 14 through the end effe_=or 12, is filtered to remove odors and infectious agents, and is returned to the environment. ~ typical filtration assembly could include a prefilter to remove large contaminants, a charcc-1 filter to remove odors, and a HEPA (High Efficiency Particle Accumulator) filter to remove inSectious agents.
End effector 12 broadl~ includes a flexible hose 16 coupled to a vacuum head 18 by a generally tubular handle 20.
The length of hose 16 can vary according to need, but would typically be from six to eight feet. The surface of hose 18 is preferably corrugated along its length to provide the hose 18 with cross sectional rigidity while allowing for axial flexi-20 bility.
Vacuum head 18 includes a generally flat collector22 having a collector top wall 22, collector bottom wall 26 and collector sidewall 28 extend ng between the collector top wall 24 and collector bottom wall 26. The collector 22 is prefe--25 ably formed from a non?orous, pl-able synthetic resin. The collector top, bottom, and sidewalls 24, 26, 28 together define a generally annular, internal plenum 30.
Collector top wall 24 includes access aperture 32.
Collector bottom wall 26 includes access aperture 34 aligned 30 with the top wall access aperture 32. Referring to Fig. 2, a layer of adhesive 36 is carried by the collector top wall l~OZ826 1 ~4, and a clear film 38 is removably carried in place over the t~p access aperture 32 by the adhesive 36. Collector bottom ~all 26 includes a first adhesive layer 40 and a clear f.lm 42 removably carried by the first adhesive layer 40. A second a-hesive layer 44 having an antiseptic embedded therein .s carrie ~y the bottom wall clear film 42. ~ sterile, peel-off shield ~6 is removably carried by the antiseptic adhesive layer 44.
The collector 22 is made of a soft and pliable material so that it will conform to the surface surrounding the surgical 0 5_te. It will be appreciated that, upon application of a vacuum t~ the collector 22, the top and bottom wall would be ursed t~sether, thereby reducing the volume of internal plenum 28.
A ~lenum support 48 formed from a porous material such as foam u-ethane is carried within plenum 28, to provide the collector 22 -~ith some rigidity without substantially detracting from t:~e flexibility of the vacuum head lB.
An end effector 50 in accordance with a second embodimer.
o- _he present invention is depicted in Fig. 5. The end effector 53 includes a flexible hose 52 similar to the hose 16 dep cted a-.d described above in conjunction with the first embodiment o the end effector 12. The flexible hose 52, however, f~lrther ir.c,udes prefilter chamber 54 and tapered connector 56.
The end effector 50 includes a vacuum head 58. Vacuum heac' 58 comprises a generally circular collector 60 connected tc flexible hose 52 by tubular handle 62. The collector 60 ir._ludes collector top wall 64, collector bottom wall 66, and curved sidewall 68 extending between the collector top wail 64 and collector bottom wall 68. Similar to the structure described above in conjunction with the first embodiment 12 of the invention, the collector top, bottom and sidewalls 64, 66, 68 define an internal plenum 70. While the shape of plenum 70 is generally 1 circular as opposed to the generally oval shape of plenum 28, it will be noted that both plenums provide for evacuation of plumes around a complete 360 arc.
Referring again to Fig. 5, it will be seen that end effector 50 includes a top wall access aperture 72, bottom wall access aperture 74, plenum support 76, and top wall clear film 78, similar to the structure described above in conjunction with end effector 12 in accordance with the first embodiment of the invention. Although not explicitly shown in Fig. 5, end effector 50 can also include adhesive layers and a clear film across bottom wall access aperture 74, similar to the structure described and shown in conjunction with end effector 12.
Each of the end effectors 12, S0 described above are advantageously extruded from a single piece of material. That is to say, that collector, tubular handle, flexible hose, and in the case of end effector 50, the prefilter chamber and connector, are formed from a unitary piece of synthetic resin or similar extrudable material.
The operation of end effector 12 will now be described, it being understood that operation of end effector 50 would be similar. The collector 22 is detachably affixed to the skin S (see Fig. 4) surrounding a surgical site by peeling off the sterile peel-off shield 46 and pressing the adhesive layer 44 carried by bottom wall 26 of the collector 22 against the skin S. It will be appreciated that the flexible nature of vacuum head 18 permits a complete, airtight seal of the bottom wall 26 against the skin S. A tear line T is formed in the clear film 38 carried by the collector top wall 24, and portions of the clear film 42 carried by the collector bottom wall 26 are trimmed away from the immediate vicinity of the surgical site.
Alternatively, the clear films 38, 42 carried by the collector -- i302826 1 top and bottom walls 24, 26, respectively, can be entirely remove-.
~pon actuation of vacuum generator 14, air is drawn into plenum 28, and is transported through flexible hose 16 and into the filter (not shown) in the vacuum generator 14. Porous plenum su2port 48 carried within plenum 30 prevents plenum 30 from collapsing in the presence of the vacuum. The plenum support 48 also has the effect of diffusing the vacuum around the plenum 28, thereby drawing air into the plenum 28 around its entire periphery, rather than solely in the vicinity of handle 20.
Moreover, drawing air through the larger opening presented by the plenum 28 reduces the noise created by the flow of air into hose 16. Gaseous waste from the interaction of lasers with tissue at the operating at the surgical site is thereby drawn into the plenum 30 and evacuated through flexible hose 16.
The plenum support 48, due to its porous nat-lre, also acts as a filter as the smoke plume is drawn through it.
Surgical instruments can be manipulated through the tear line T in clear film 38. Alternatively, the clear film 38 can be completely removed. It will be ap?reciated that the vacuum, and drawing effect, presented by the plenum to the surgica:
site is increased by leaving the clear film 38 in place.
Operation of end effector 50 in accordance with the second embodiment of the invention is similar to that described above. The prefilter contained within prefiiter chamber 54, however, removes certain of the contaminants ~ithin the evacuated smoke prior to entry of the smoke into the vacuum generator 14. The necessity for cleaning the filters within vacuum generato~
14 after each use is thereby avoided. Moreo~er, the entire end effector 50 can be advantageously and hygienically disposed of after a single use, without the necessity of handling the contaminated prefilter.
This invention relates to equipment for the removal of the gaseous byproducts of laser surgery. In particular, it relates to an end effector for a vacuum filtration system that efficiently removes smoke plumes produced through the use of lasers at a surgical site.
