ABSTRACT:
A method for forming an arthroscope having an inclined angle of view includes providing an inner lens tube member, an outer tube member, and an annular shim member. The annular shim member is positioned about an outer peripheral portion of the inner lens tube member and includes an upper portion defining an outer positioning surface and side edges angularly offset relative to an optical axis. The inner lens tube member and annular shim member are positioned within the outer tube member while a plurality of optical fibers are positioned therebetween. The optical fibers are oriented about the outer positioning surface and side edges such that the optical fibers are angularly offset relative to the optical axis. Alternatively, a shim member may be provided that is arcuate and defines a cross-sectional dimension approximating a maximum inner dimension of the outer tube member, wherein the shim member engages the outer tube member to stabilize the inner lens tube member therein.
