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 threadedbone 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 screwingrod 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 equipment, in particular to a special tool for orthopedic medical internal and external fixation equipment. Background technique [0002] At present, various orthopedic medical devices used to treat diaphysis, intertrochanteric fractures and femoral neck fractures of extremities have made a lot of progress, such as invention patent ZL200710012279.5 "Unilateral adjustable external fixator and its combined use device"; invention patent ZL200810012533.6 "functional combined fixator for distal radius fractures" all provide good orthopedic medical devices. During the installation of orthopedic medical internal and external fixation instruments for surgery, the use of corresponding special tools is required to cooperate with them in order to receive better surgical results. Among the tools currently used, electric drills are used to drill bone holes. However, the loading and unloading of the used...
