Description
Technical field
This utility model relates to the orthopedic medical device field, at length says it is a kind of orthopaedics nail pulling device.
Background technology
As everyone knows, treatment fracture generally needs to implement internal fixation operation, be about to the reduction of the fracture after, the fracture after blade plate of making by means of metal material and screw will reset couples together.Get in the steel plate process at enforcement internal fixation and second operation, often make screw fracture and stay in the body because of various reasons, extremely difficult the taking-up.Several nail modes of getting are arranged at present, revolve as the metal exposed portions serve is clamped brute force, perhaps bore a plurality of apertures around broken nail, firmly cutter is disconnected between the hole, connects the bone piece and together takes out broken nail.Its shortcoming is to produce little effect, and perhaps destructiveness is too big, increases wound and operating time, also easily causes the secondary fracture, increases medical expense, just simply abandons getting nail sometimes, allows it stay in the body throughout one's life.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of orthopaedics nail pulling device, and is simple in structure, easy to operate, and tissue injury is little than the operation of common apparatus, and the time is short, and rehabilitation is fast.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of orthopaedics nail pulling device, be provided with fixture and device for fetching nail, it is characterized in that, the fixture front end is provided with annular cutter, rear end and device for fetching nail socket, be provided with fixed core in the fixture, fixed core is connected and fixed with screw and fixture, device for fetching nail is a hollow cylindrical, front end is provided with the conical surface, and the open rearward end inwall is provided with screw thread, is provided with the pawl axle in the device for fetching nail, the axle front end is provided with three steel pawls, and the rear end is provided with screw thread and device for fetching nail spins.
The beneficial effects of the utility model are, and are simple in structure, easy to operate, and littler than common apparatus operation tissue injury, the time is short, and rehabilitation is fast.
