Abstract
A clamp for the rapid and accurate positioning of a threaded fixation pin has a central body defining a channel therethrough for receiving a fixation pin. The clamp also includes a locking member with a lower surface adapted to engage and mate with the threads of the fixation pin. Thus, the fixation pin can be rapidly inserted into the desired bone structure by rotating the fixation pin, and as the fixation pin is rotated, it also advances forward due to the engagement of the threads of the fixation pin with the locking member of the clamp. If the forward advance caused by the engagement of the threads of the fixation pin with the locking member can not keep pace with the cutting action, the resultant resistance to insertion in the form of a rearward directed force will cause the locking member to rise up and disengage the threads of the fixation pin.
