Abstract
An orthopedic clamp to assist in reducing the displacement between bone ends of a fracture, and to position a fixation device, during open fracture reduction surgery is described. The clamp includes a holder to hold the fixation device against the bone. The clamp may also swivel in relation to the holder while the position of the fixation device remains unchanged. The clamp may be modular so that components thereof may be released and/or attached.
Claims15
A device to assist in surgery, comprising:
- a first tong that includes a distal end which is configured to engage a fractured bone;
- a second tong that includes a distal end, and that is moveably coupled to the first tong;
- a holder that is moveably coupled to the distal end of the second tong, that is configured to position a fixation plate between the holder and the fractured bone, and that includes a frame surrounding an opening which provides access to the fixation plate;
- wherein the frame is sized to engage edges of the fixation plate;
- wherein the frame includes two sides and two ends;
- wherein the two sides form lips that engage two edges of the fixation plate;
- and
- wherein the two ends form lips that engage two other edges of the fixation plate.
An orthopedic clamp for assisting with open fracture reduction surgery, comprising:
- a first tong that includes a distal end which is configured to engage a fractured bone;
- a second tong that is movably coupled to the first tong and that includes a release mechanism;
- a releasable portion that is releasably attached to the release mechanism, wherein the releasable portion includes a frame that is configured to position a fixation plate between the frame and the fractured bone;
- and
- wherein the release mechanism includes a lever or flip switch assembly with an extendable and retractable pin that engages the frame.
An orthopedic clamp for assisting with open fracture reduction surgery, comprising:
- a first tong that includes a proximal end having a handle and a distal end which is configured to engage a fractured bone or bone ends;
- a second tong that includes a proximal end having a second handle, a mechanism rotatably attaching the second tong to the first tong, and a release mechanism, wherein the release mechanism includes a keyless chuck having a non-circular receptacle;
- and
- a releasable portion that includes:
- a holder which comprises a radiolucent material and which is configured to position a fixation plate between the holder and the fractured bone or bone ends;
- a swivel that is connected to the holder and that allows the holder to rotate relative to the second tong;
- and
- a pin that is connected to the swivel and that has a non-circular cross-section which releasably engages the receptacle.
