Abstract
A fracture reduction clamp for the reduction of a fractured bone. The fracture reduction clamp is particularly suitable for surgical procedures wherein a bone having a fracture is to be fixated with a fixation apparatus after reduction of the bone with a strap. The fracture reduction clamp includes a bifurcated strap guiding head for contacting and firmly gripping the fractured bone, and a strap retainer disposed between the strap guiding head and a rotatable strap tensioner for retaining the ends of the strap being used to reduce the fractured bone. The strap guiding head can include a retractable spike for enhancing the grip of the fractured bone by the fracture reduction clamp. Rotation of the strap tensioner will tighten or loosen the strap about the fractured bone.
Claims20
A fracture reduction clamp for tightening a strap about a fractured bone, said clamp comprising:
- a substantially hollow tubular body having opposing first and second ends, a coextensive bore therethrough and two slots interposed said first and second ends and intersecting with said bore;
- a handle rotatably engaged with said first end of said body;
- an externally threaded drive shaft which is fixedly engaged with said handle, disposed within said bore of said body, substantially coaxial with said body, and accessible through said two slots of said body;
- a strap retainer which is threadably engaged with said drive shaft, is slidable with respect to said body and extends through said two slots of said body;
- and
- a strap guiding head engaged with said second end of said body and comprising a spike and at least one strap guide which permits passage of a strap therethrough;
- wherein rotation of said handle causes displacement of said strap retainer with respect to said head.
