Abstract
A surgical tool holder comprises a shank having first driveable end and second coupling end, the second end comprising a coupling device having interfaces for mating with corresponding structures on the inside 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 a forward 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 disassembly of the locking sleeve, spring and coupling device for cleaning and component sterilization.
