Embodiment Construction

[0016] like figure 1 As shown, the steel plate structure for orthopedic internal fixation of the present invention includes a steel plate body and locking screws. The steel plate has a plurality of locking screw holes. According to needs, the locking screw holes can be divided into two types, one is the key nail hole position , and the other is the non-key nail hole position (non-nail setting area). The locking screw is fixed on the fracture site through the key locking screw hole, the non-key nail hole is left blank, and the locking screw does not pass through the non-key nail hole.

[0017] The internal fixation steel plate structure uses blocking bolts to fasten and cover the locking screw holes belonging to the non-key nail holes through non-key nail holes. The shape and thread of the body of the blocking bolt closely match the locking screw holes through which it passes. , and the length of the blocking bolt body does not exceed the thickness of the internal fixing steel...

Abstract

A internal fixation steel plate structure for the orthopedics department comprises a steel plate body and locking screws, wherein the steel plate body is provided with a plurality of locking screw holes, the locking screw holes can be divided into two types according to requirements, one type of the locking screw holes are key screw hole positions, and the other type of the locking screw holes arenon-key screw hole positions (non-screw-fixation areas). The locking screws penetrates through the key locking screw hole positions to be fixed to a fracture position, and the non-key screw hole positions can be reserved. The internal fixation steel plate structure is characterized in that blocking bolts can be used for covering the locking screw holes belonging to the non-key hole positions through the non-key screw hole positions, the shape and threads of blocking bolt bodies are closely matched with the locking screw holes where the blocking bolts penetrate, and the length of the blockingbolt bodies is not larger than the thickness of an internal fixation steel plate.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a structure for orthopedic internal fixation steel plates. Background technique [0002] Locking and locking compression plates are internal fixation devices commonly used by orthopedic surgeons to treat limb fractures, including plates and screws. Among them, the steel plate has locking holes and pressurized locking holes. Doctors can choose to apply different types of steel plates and screws for fixation according to the patient's condition and fracture type. The existing plate and screw materials for clinical application, regardless of domestic or imported materials, regardless of the difference in shape and material, or data such as length and diameter, are composed of two parts: the plate body and the screw. This is already a fixed form in various device manufacturers. [0003] For extremity traumatic fractures, the above-mentioned open reduction and internal fix...
