International Classification:

A61B 106

US Classification:

600178

Abstract:

An arthroscope includes an frame member, an illumination system and a light guide connection port associated with the frame member for connecting to a light guide to transfer illumination light to the illumination system. The light guide connection port includes a support member having a tapered inner wall portion for supporting a transmissive element having a tapered portion. The support member includes a plurality of inner mounting projections extending from the tapered inner wall portion and being radially arranged and positioned to contact the outer surface of the light transmissive element to maintain the light transmissive element in spaced relation relative to the tapered inner wall portion.

Abstract:

A disposable rigid arthroscope having an inclined angle of view includes a frame member, an outer tube member extending distally from the frame member, an inner lens tube member eccentrically disposed within the outer tube member, an optical system disposed within the inner lens tube member and having a mechanism for altering the field of view of the optical system with respect to the optical axis and an illumination system including a plurality of optical fibers. The optical fibers of the illumination system are assembled and oriented to emit light in the general direction of the inclined field of view to sufficiently illuminate the surgical field. The materials of the arthroscope are advantageously selected to minimize the overall cost of the scope while providing for high level optical performance.
