Abstract

The invention relates to the technical field of orthopaedic medical treatment instruments, in particular to a special tool used by an internal and external fixation instrument for orthopaedic medical treatment. The special tool comprises a three-jaw annular grab, a tapping drill, a graduated scale, a drill fixture, a quick connector, a nail grasping elastic cannula, a screwing-out pipe, a left-right revolving straight type screwing rod or a left-right revolving ratchet screwing rod, and a short screwing rod or a long screwing rod, wherein the three-jaw annular grab is used for maintaining a fracture alignment after restoration; the tapping drill is used for drilling a threaded bone hole on the fracture alignment position; the graduated scale is used for measuring the depth of the threaded bone hole; the drill fixture is used for chucking the tapping drill; the quick connector is used for quickly replacing the drill fixture; the nail grasping elastic cannula is used for transferring a bone-joining nail or a bone-joining needle into the threaded bone hole; the screwing-out pipe is used for screwing out the broken bone nail or the broken bone needle which is positioned in the threaded bone hole; the left-right revolving straight type screwing rod or the left-right revolving ratchet screwing rod is matched with the screwing-out pipe; and the short screwing rod or the long screwing rod is matched with the left-right revolving straight type screwing rod or the left-right revolving ratchet screwing rod. The special tool used by the internal and external fixation instrument for the orthopaedic medical treatment can reduce the iatrogenic injury as much as possible, shorten the operation time, relieve the patient pain and ensure the rapidity and the safety of the operation.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical instruments, in particular to a special tool for orthopedic medical internal and external fixation instruments. Background technique [0002] At present, various orthopedic medical devices for the treatment of extremities, intertrochanteric fractures and femoral neck fractures have made a lot of progress, such as the invention patent ZL200710012279.5 "Single-sided adjustable external fixator and its combined use device"; invention patent ZL200810012533.6 "Functional Combined Fixator for Distal Radius Fracture", all of which provide good orthopedic medical devices.
