Abstract
A coupling arrangement for selectively coupling and uncoupling the handle and the blade of a surgical instrument, such as a broach, includes a key projecting axially from the handle and receivable within a first recess portion in the blade to engage locking pins upon transverse movement of the key into locking engagement with the locking pins, and a plunger selectively movable into a further recess portion contiguous with the key for precluding relative movement of the handle and the blade in the transverse direction so as to maintain the key in locking engagement, the plunger being selectively retractable from the further recess portion to permit relative transverse movement of the handle and the blade, and consequent movement of the key out of locking engagement with the locking pins, to enable uncoupling of the handle from the blade.
