The present invention provides a clamp assembly which allows the surgeon to snap a bone fixation assembly onto a bone fixation rod at an intermediate location along the length of the rod. It is not necessary to 'thread' the clamp onto the rod starting at the end and sliding it down the length of the rod to the desired location. In particular, this invention provides a novel clamp assembly for use with standard bone fixation rods, and bone pins. The clamp allows the interconnection of a bone fixation rod with a bone pin locking assembly including a bone pin vise. The clamp is a single-piece construction, having a jaw capable of loosely capturing the bone fixation rod 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.

Multi-pin clamp and rod attachment

A fixation rod clamp is for coupling a bone pin locking assembly to a bone fixation rod. The clamp comprises a rod attachment portion including a jaw portion and a coupling portion, the jaw portion having first and second opposing jaws extending in a first direction, the jaws forming an opening there between configured to receive the bone fixation rod, the coupling portion extending from the jaw portion in a second direction; and a coupling having a pin vise cooperating portion to engage the bone pin locking assembly and a clamp cooperating portion configured to receive the coupling portion. The jaw portion is configured to engage the bone fixation rod when the bone fixation rod is located within the opposing jaws to thereby mechanically couple the bone pin locking assembly to the bone fixation rod.

Multipin clamp and rod attachment

The present invention provides a simplified external bone fixator assembly which allows the surgeon to snap the assembly onto a bone fixation rod at an intermediate location along the length of the rod. It is not necessary to &ldquo;thread&rdquo; the assembly onto the rod starting at the end and sliding it down the length of the rod to the desired location. In particular, this invention provides a novel bone pin locking assembly for use with standard bone fixation rods, and bone pins. The bone pin locking assembly includes a bone pin vise, a single-piece fixation rod clamp, and a coupling 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 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.
