Abstract
Abstract The present invention is broadly concerned with an improved surgical drape for an endoscopic video camera device which provides a sealed, sterile encasement of the camera and its associated transmission cable and which permits quick, easy interchanging of various endoscopic rod lenses without contamination of the camera head or cable or distortion of the camera image. More particularly, it is concerned with a drape having an opening for insertion of a camera and cable, a clear lens, and structure for constricting the drape around the camera and cable.

Claim 9
Dependent Claim
118 words
In combination with a remote surgical visualization system having a rod lens assembly for insertion into the body of a patient coupled in mating engagement with a camera lens assembly including a lens portion, a video display device, and a cable member remotely intercoupling said camera lens assembly and said video display device, the improvement comprising a tubular drape member covering said camera lens assembly and said cable member for preventing septic contact of said camera lens assembly and said cable member, said drape having an elongate body, an open end and a closed end, said closed end including an integral lens having a position interposed between said matingly engaged rod lens assembly and said camera lens assembly.
Claim 10
Dependent Claim
42 words
The apparatus as set forth in claim 7, wherein said drape further includes removable support means inwardly adjacent said open end for supporting said tubular drape member in telescoped relationship over said support means and forming an insertion canal for said camera.
Claim 11
Dependent Claim
20 words
The apparatus as set forth in claim 8, wherein said support means comprises a pair of elongate rectangular support members.
Claim 12
Dependent Claim
23 words
The apparatus as set forth in claim 7, wherein said drape further includes means for constricting said tubular member around said cable member.
Claim 13
Dependent Claim
23 words
The apparatus as set forth in claim 10, wherein said constricting means comprises an elastic band in coaxial relationship with said tubular member.
Claim 14
Dependent Claim
79 words
The apparatus as set forth in claim 7, wherein said drape further includes: (a) removable support means inwardly adjacent said open end for supporting said tubular drape member body in telescoped relationship over said support means and forming an insertion canal for said camera lens assembly; and (b) elastic constricting means in coaxial encircling relationship with said tubular drape member and said support means for constricting said tubular member around said cable member upon removal of said support means.
Claim 15
Independent Claim
138 words
A method of draping a remote surgical visualization system having a rod lens, a camera including a lens portion, a video display, and a cable member remotely intercoupling said camera and said display, for preventing septic contact of said camera and said cable when a drape is placed in covering relationship over said camera and said cable, comprising the steps of: (a) providing a tubular drape member having an elongate body, an open end and a closed end, said closed end including an integral drape lens; (b) inserting said camera into said tubular drape member through said open end and juxtaposing said camera lens portion against said drape lens while permitting said cable member to extend outwardly from said open end; and (c) coupling said rod lens with said camera lens portion while interposing said drape lens therebetween.
