Method and apparatus for performing percutaneous bone surgery and new pin implant

摘要

Apparatus and method of performing percutaneous bone surgery particularly to repair a particular fractured trochanteric portion of a femur. The technique includes the making of a small first incision to the bone, introducing a tubular guide, placing a drill in the tube activating the same, drilling a bore into the bone, withdrawing the drill and guide and inserting a new pin and pin insertion means to place the pin in position in the bore and due to its design leaving a portion extending from said bone bore to abut and lie against the femur at approximately 145° to the angle of the portion of the pin in the bore. In addition the pin insertion means includes a portion adapted to abut the exterior skin and serve as a guide for an additional small incision, insertion of a tubular guide, placing a drill in the guide, drilling a second bore below the first bore and at an angle thereto. The pin includes a bore which is aligned with the tubular guide when in its second position and is adapted to receive a fastening means to lock the pin to the bone during the bone healing process.
