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 oriented by a shim member to emit light in the general direction of the inclined field of view to sufficiently illuminate the surgical field. The shim member includes opposed side edges that are angularly oriented relative to the optical axis and a proximal end portion extending along an inner periphery of the outer tube member to define a major cross-sectional dimension approximating a maximum inner dimension of the outer tube member.
