<p>The present invention provides a simplified external bone fixator assembly which allows the surgeon to snap the assembly onto a bone fixation rod (100) at an intermediate location along the length of the rod (100). It is not necessary to 'thread' the assembly onto the rod (100) starting at the end and sliding it down the length of the rod (100) to the desired location. In particular, this invention provides a novel bone pin locking assembly for use with standard bone fixation rods (100), and bone pins (28). The bone pin locking assembly includes a bone pin vise a single-piece fixation rod clamp (56), and a coupling (52) to allow relative adjustment of the pin vise and the rod clamp. The rod clamp is a single-piece construction, having a jaw capable of loosely capturing the bone fixation rod (100) when the surgeon presses the jaw onto the rod. The assembly may be rigidly fixed to the rod using a bolt which tightens the jaw onto the rod.</p> |
