Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
230 words
An attachment for an endoscope of the type to be inserted through the cervix into the uterine cavity and having a light and image transmitting tube with an eyepiece end for viewing through the tube, said eyepiece end having a portion of increased transverse dimension with respect to the transverse dimension of said tube, and a distal viewing end for location close to the uterine cavity wall under investigation, said attachment comprising: a rigid, transparent, generally spherical bulb of a diameter substantially greater than the diameter of the light and image transmitting tube for separating the walls of the uterine cavity, said bulb having a relatively thin wall and an inside radius of approximately between 3 and 4mm, said bulb being carried by the end of a rigid outer tube to which said bulb is smoothly faired, said outer tube having an inside diameter approximately equal to the outside diameter of said light and image transmitting tube so that said outer tube snugly fits over said light and image transmitting tube, the length of said outer tube being such that when the end of said outer tube opposite said bulb abuts the portion of increased diameter of said eye piece end, the distal end of the outside surface of said bulb is spaced approximately between 2 to 3 mm beyond the distal end of said light and image transmitting tube.
