Abstract

The embodiment of the invention provides a composite screw which is used for solving the problem that a screw in the prior art is poor in firmness and easily falls.According to the technical scheme, the composite screw comprises a screw body and a PEEK cap which are mutually independent, wherein the screw body comprises a threaded portion and a head portion, the head portion is provided with a hole, and the PEEK cap is located on the outer side of the head portion and is connected with the head portion.The embodiment of the invention further provides a composite fixing assembly.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of medical devices, in particular to a composite screw. The embodiment of the present invention also relates to a composite fixing component. Background technique [0002] Fracture refers to a disease in which the integrity and continuity of the bone is interrupted, and the bone is partially or completely broken due to trauma or internal injury. Fractures are basically caused by accidental injuries, and accidental injury accidents often occur in the rapidly developing modern life. [0003] In the treatment of fractures, after the fracture is reduced, it needs to be fixed to prevent further displacement. The fixation method can be divided into internal fixation and external fixation according to the fixation method. The main advantage of internal fixation is that it can better maintain the anatomical reduction of the fracture, which is more direct and effective than simple external...
