Problems solved by technology

The current fixed locking plate is generally designed into different shapes according to the anatomical type. It is made of metal plate. In order to realize the fixation, locking holes of different hole shapes and shapes are opened on the corresponding position of the fixed locking plate, such as elongated locking holes, etc. , the matching fixing screw is implanted and fixed from the locking hole, but the current fixing screw has a simple structure and cannot achieve an effective fixing effect after implantation. After being easily loosened, the bone plate is not fixed well, and a second implantation is required. Increase the cost and pain of the patient, and is not conducive to the effective rehabilitation of the patient's fracture

Abstract

The invention belongs to the technical field of medical instruments and particularly relates to a bone joining plate locking screw. The bone joining plate locking screw comprises a screw body provided with a cap and a self-tapping portion, a thread matched with a locking hole of a bone joining plate is formed on the outer circumferential surface of the cap, and the self-tapping portion is provided with scrap outlet grooves and self-tapping threads. The bone joining plate locking screw has the advantages that the thread matched with the locking hole of the bone joining plate is formed on the outer circumferential surface of the cap, and the self-tapping portion is provided with the scrap outlet grooves and the self-tapping threads, thus, implantation efficiency can be improved and implantation hindrance is reduced; meanwhile, since the external thread of the cap is matched with the locking hole of the bone joining plate, powerful locking can be guaranteed, screw shedding after implantation can be prevented and recovery after bone joining is benefited.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a locking screw for a bone plate. Background technique [0002] When the medical operation operation needs to fix the damaged bone of the fracture patient by locking the fixing plate, firstly, the bone will be punched, and then the screw will be implanted. The current fixed locking plate is generally designed into different shapes according to the anatomical type. It is made of metal plate. In order to realize the fixation, locking holes of different hole shapes and shapes are opened on the corresponding position of the fixed locking plate, such as elongated locking holes, etc. , the matching fixing screw is implanted and fixed from the locking hole, but the current fixing screw has a simple structure and cannot achieve an effective fixing effect after implantation. After being easily loosened, the bone plate is not fixed well, and a second implantation is...
