Abstract

The invention relates to medical appliances of orthopedic operations, and discloses a trepan broken-nail extractor. In the invention, an inverted-tooth trepan is arranged at the front port of a holding handle of the trepan broken-nail extractor, and the rear end of the holding handle is matched with the drill opening of an electric drill. Because the rear end of the holding handle can be matched with the drill opening of the electric drill, electromotive power can be used for replacing manpower to extract a broken nail when the broken nail is extracted. The invention greatly improves the efficiency of broken-nail extraction, saves the time and the labor and shortens the operation time, thereby reducing the time of intraoperative hemorrhage and wound exposure and reducing the incidence rate of postoperative wound infection.

Description

technical field [0001] The invention relates to a medical device for orthopedic surgery, in particular to a technique for taking out broken screws in bone. Background technique [0002] In orthopedic surgery and emergency department, the rate of fracture patients is very high. Among these fracture patients, the most effective and commonly used method is to use copper plates and screws for internal fixation after butt reduction of the fracture. The curative effect is better. [0003] Although the application of plate screws has greatly improved the treatment effect of fractures, screw breakages occur from time to time during clinical use. Screw breakage often leads to failure of the entire internal fixation system, decreased fracture healing rate, and formation of pseudarthrosis, etc., which ultimately affect clinical results. . In addition, after the screw is implanted into the bone, the phenomenon of screw breaking due to the bearing force and muscle reaction force is oft...
