Abstract
A hammer drill attachment is provided for attachment to a bi-directional surgical drill. The attachment comprises a lengthwise adapter to engage a chuck of the surgical drill, a transmission mechanism, and a quick-release mechanism. The transmission mechanism comprises a pair of toothed plates, the teeth of a proximal plate configured to permit engagement with the teeth of a distal plate. When the proximal plate rotates in a first direction, the proximal plate transmits a rotational motion to the distal plate. When the proximal plate rotates in a second direction, the proximal plate transmits an axial percussive force to the distal plate. The quick-release mechanism comprises a socket to receive a collet, a socket seater, and a latching arm to move the socket seater with respect to the socket, thereby seating or unseating the collet in the socket.
