COLLETED ADJUSTABLE FLAT DENTAL TOOL

摘要

A dental implement designed to be retained for reciprocating movement by the sleeve member of a dental handpiece. The dental implement is comprised of a flat dental tool having a flat blade portion and a flat shank portion. The flat blade portion can also be formed with a triangular or arcuate cross section while retaining the flat shank portion and the blade edges can be straight or have a saw-tooth configuration. A removable tool holder has a slot to receive the dental tool and an outside cylindrical shape complementary with the bore of the sleeve member. Forces applied to the tool holder control the displacement of locking protrusions on the tool shank to selectively permit the tool to be driven in a reciprocating movement with or without rotation and to be removed entirely from the sleeve member.
