Endoscopic shaver blade with resilient cutting edges

摘要

A rotating endoscopic shaver blade assembly adapted for side-cutting and end-cutting. A pair of longitudinally extending, symmetrical fingers (20 and 22) extends from the distal end of an elongated tubular inner member (14) and are juxtaposed adjacent a window at the distal end of an elongated tubular outer member. Each of the fingers is provided with laterally facing (39,40,42 and 43) and transversely facing (41 and 44) cutting edges and has a curvilinear profile terminating at a distal tip. The distal tips of the fingers are separated by an axially aligned gap (60) which enables limited stress-relieving radial movement of the fingers. <IMAGE>
