Hollow small diameter tool holder for surgical use

A surgical tool holder comprising a shank having first driveable end and second coupling end, the second end comprising a coupling device having interfaces for mating with corresponding structures of a hollow surgical tool, a first interface mating with a centering structure near a base end of the tool and a second interface mating with a second structure adjacent to an opposite apex end of the tool and distal from the base end of the tool, the tool being held in functional assembly to the shank by a releasable locking mechanism comprised of a locking sleeve slideably disposed about the shank, a spring biased against the coupling device by the locking sleeve, and a connection device retaining the locking sleeve in a fixed position during use, whereupon release of the connection device enables quick removal of the locking sleeve, spring and coupling device for cleaning and component sterilization, and wherein the second interface is a transverse bayonet recess in the end of the shank and which mates with a cross bar.
