Abstract: A surgical apparatus particularly useable for arthroscopic surgery includes a tool insertable in a hollow, powered handpiece. The tool includes a hollow housing in which a driven member is rotatably sleeved, which driven member is provided at its forward end with a material working portion of suitable surgical type. The tool housing and driven member adjacent their rear ends both include funnel-shaped portions adapted to receive corresponding pin-like elements on the handpiece for respectively angularly fixing the tool housing and rotatably driving the driven member.

Abstract: Surgical apparatus in which a locking device is provided for releasably securing a surgical tool in a sleeve. A lock housing is movable on the sleeve, the lock housing having a through opening through which the tool is insertable to be received into the sleeve. A lock member on said lock housing has a push button actuable for opening the lock housing to reception of the tool through the through opening and into the sleeve. The lock member has means for automatically locking the tool against removal from said lock housing upon release of the push button. A tapered part on the sleeve receives a correspondingly tapered portion of the tool to thereby assure a snug fitting connection of said sleeve with the tool.
