Abstract
Abstract A speculum instrument with improved lighting means therefore is disclosed wherein the speculum barrel, which may be a single use disposable material, tapers to become increasingly larger at its proximal end. A smaller cylindrical sleeve member having a light transmitting flange or wall at one end, has the flange affixed into the larger proximal end of the barrel with the sleeve extending therefrom, to define an annular contamination isolated area with the flange directed towards the distal end of the barrel. A handle member containing a light source releasably engages the speculum barrel and provides lamp means in the isolated area to direct light through the barrel. An obturator in the barrel may be withdrawn through the sleeve.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
In a speculum instrument including a speculum barrel and obturator assembly wherein said barrel includes a smaller diameter flanged sleeve means with the flange engaging said barrel and said sleeve projecting from the proximal end of said barrel and through which said obturator may be withdrawn the improvement of a handle lighting unit adapted to receive said sleeve therein comprising in combination a. a handle part, b. an annular lighting head part on said handle part and adapted to fit over said sleeve, c. a concentric ring of lamps positioned in said annular lighting head and closely surrounding said sleeve to pass light directly through said flange and into the bore of said barrel, d. releaseably securing means in said annular lighting head to releaseably secure said barrel to said annular lighting head e. and means to sealingly engage said annular lighting head part to said barrel around said lamp ring.
Claim 2
Dependent Claim
