Problems solved by technology

[0002] For a long time, most fractures and bone orthopedics have adopted bone plate technology. The contact and fixation between the bone plate and the bone is based on mutual friction, so the holes of the bone plate only have the function of pressurizing and tensioning the bone in close contact.
The internal fixator is different from the bone plate. There is a certain gap between the main body of the fixator and the bone. This gap is for not destroying the periosteum and maintaining the blood supply of the fracture end, accelerating fracture healing and improving the quality of fracture healing. Therefore, internal fixation The main body of the frame and the screw must be locked and pressurized, and it must be very stable. At present, there is no report about the locking and pressure holes of the internal fixation frame.

Embodiment 1

[0012] Embodiment 1, a kind of internal fixation frame locking pressure hole, refer to figure 1 , figure 2 , image 3 As shown, the hole is partially overlapped by a locking hole and a pressure hole. The locking hole is a tapered threaded through hole, and the pressure hole is an unthreaded through hole with an arc-shaped pressure slope. The locking pressure hole 2 Evenly distributed on the internal fixator 3 with a 0.3mm-0.5mm gap 6 with the bone; through the locking pressure hole slot, the locking screw 4 and the end of the pressure bone screw 1 enter the bone 5, locking the pressure hole 2, locking screw 4. The pressurized bone screw 1, the internal fixator 3 and the bone 5 constitute a non-contact fixed frame system.

[0013] During use, by locking the pressure hole, the end of the locking screw uses the locking screw to fix the internal fixator on the fracture site, and the pressure screw 1 pressurizes the fracture end, and the internal fixator is kept in contact with ...

Abstract

The invention provides a locking pressurizing hole of an internal fixed frame. The locking pressurizing hole is characterized in that the locking pressurizing hole is formed by partially overlapping locking holes and pressurizing holes; the locking holes are conical screw thread through holes; the pressurizing holes are unthreaded through holes with arched pressurizing slopes; and the locking pressurizing holes are uniformly distributed in the internal fixed frame, wherein the gap between the internal fixed frame and the skeleton ranges from 0.3mm to 0.5mm.

Description

technical field [0001] The invention relates to a locking pressurizing hole in an orthopedic internal fixation frame system. Background technique [0002] For a long time, most fractures and bone orthopedics have adopted bone plate technology. The contact and fixation between the bone plate and the bone is based on mutual friction. Therefore, the holes of the bone plate only have the function of pressurizing and tensioning the bone in close contact. The internal fixator is different from the bone plate. There is a certain gap between the main body of the fixator and the bone. This gap is for not destroying the periosteum and maintaining the blood supply of the fracture end, accelerating fracture healing and improving the quality of fracture healing. Therefore, internal fixation The main body of the frame and the screw must be locked and pressurized, and it must be very stable. At present, there is no report about the locking and pressure holes of the internal fixation frame....
