ABSTRACT:
Plier-like instruments for dental and medical use which can be readily disassembled for cleaning and sterilization and then quickly reassembled for use. No additional tools are needed for assembly and disassembly, and the manipulations are simple motions that may be accomplished even under sterile conditions wearing surgical gloves. The handles are spread apart to disengage circular segments of locking ribs on one handle with circular segments of channel and retaining lips on the other handle. A piloting shaft equipped with expanding spring ring maintains smooth, aligned operation of the instruments. There are no loose parts to manipulate in assembly or disassembly, and no additional tools are required.
