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 tool is disclosed for use in forming holes in bone and for driving a cannulated fastener into the formed hole. The tool may having a cutting tip for drilling a hole into bone, and may have a shaft and sleeve for accepting the cannulated fastener and for driving it into the drilled hole. The tool may be adjustable to allow fasteners of different lengths to be accepted, while ensuring that a portion of the cutting tip protrudes beyond the end of the fastener. A multiple-screw tool is also disclosed that allows more than one cannulated fastener at a time to be stacked on the tool, thus speeding the installation process.

Adjustable tool for cannulated fasteners

A bone fixator for securing a first bone portion in a position relative to second bone portion is disclosed, including at least two clamping assemblies each for receiving at least one bone pin and a main body disposed between the clamping assemblies. The main body includes at least one joint for orienting the clamping assemblies with respect to each other. The at least one joint may permit pivoting or rotation. Some joints permit the articulation of several components to be simultaneously and releasably lockable.

Adjustable fixator

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.

A simplified external bone fixator assembly is provided which allows the surgeon to snap a bone fixation rod into the assembly at any location along the length of the rod. The invention does not require 'threading' of the assembly onto the rod starting at the end and sliding it down the length of the rod to the desired location. In particular, a bone pin locking assembly is provided for use with standard bone fixation rods and bone pins. The assembly includes a bone pin vise, a single-piece fixation rod attachment member and a coupling to allow relative adjustment of pin vise and rod attachment member. The single-piece rod attachment member has two opposing jaws that loosely capture the bone fixation rod when the surgeon presses the rod into the attachment member. The assembly may be rigidly fixed to the rod using a bolt which tightens the attachment member onto the 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.

A clamp for fixing bone pins or wires to an external frame is disclosed. The clamp has a central post, an upper vise plate and a lower vise plate urged together on the post, by a spring for provisional placement, a nut for positively locking the vise plates together on a frame, and a pin clamp that can be moved along the axis of the central post, and can receive and clamp either a bone pin or a bone wire. The pin or wire has unlimited angular movement in two planes. The clamp is a captive unit that requires no intraoperative assembly.
