Abstract
Abstract This invention is directed to a video cervicoscope system. More particularly, this invention is directed to a video cervicoscope system for the examination of the cervix comprising: a rigid, elongated tubular member having a light guide; imaging means at the distal end of said tubular member, a disposable, light-transmitting, sleeve diposed about the distal end of said tubular member; and transmitting means to transmit an image viewed by said imaging means proximally to a control box wherein said image is received and stored.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
119 words
A rigid video cervicoscope system for the examination of the cervix, comprising: a rigid elongated tubular member having proximal and distal ends and having a light guide disposed toward said proximal end; imaging means at the distal end of said tubular member; a disposable sleeve having proximal and distal ends disposed about at least the distal end of said tubular member, the proximal end of said sleeve being adapted to be positioned adjacent to the light guide so that light is transmitted distally substantially through the wall of the sleeve to illuminate a viewing area; and transmitting means to transmit an image viewed by said imaging means proximally to a control box wherein said image is received and stored.
Claim 2
Dependent Claim
119 words
A rigid video cervicoscope system for the examination of the cervix, comprising: a rigid elongated tubular member having proximal and distal ends and having a light guide disposed toward said proximal end; imaging means at the distal end of said tubular member; a disposable sleeve having proximal and distal ends disposed about at least the distal end of said tubular member, the proximal end of said sleeve being adapted to be positioned adjacent to the light guide so that light is transmitted distally substantially through the wall of the sleeve to illuminate a viewing area; and transmitting means to transmit an image viewed by said imaging means proximally to a control box wherein said image is received and stored.
Claim 3
Dependent Claim
17 words
The system of claim 1, wherein the distal end of the disposal sleeve comprises a cover glass.
Claim 4
Dependent Claim
14 words
