Memory alloy rib bone plate

Abstract

The invention discloses a memory alloy rib bone plate which comprises a flat longitudinal beam with side angles ranging from 90 degrees to 180 degrees. A plurality of surrounding arms are symmetrically arranged on two sides of the flat longitudinal beam, end teeth are arranged on the surrounding arms positioned at two ends of the flat longitudinal beam, the surrounding arms are positioned at two ends of a boundary which is the middle of the flat longitudinal beam, an elliptical structure is formed by each pair of surrounding arms positioned at one end of the flat longitudinal beam, and a circular structure is formed by each pair of surrounding arms positioned at the other end of the flat longitudinal beam. The memory alloy rib bone plate has the advantages that the end teeth can prevent the memory alloy rib bone plate from axially moving, and accordingly fixation can be reinforced; the memory alloy rib bone plate with the structure is designed according to physiological structures of skeletons of posterior ribs and can cling to the skeletons after being mounted, accordingly, fixation can be reinforced, and the memory alloy rib bone plate is favorable for normal healing of the skeletons; the middle of the flat longitudinal beam is free of surrounding arms, accordingly, the memory alloy rib bone plate can avoid fracture and injury locations of the ribs, and compression on bone broken ends due to the surrounding arms can be eliminated; implantation and fetching operation in surgical procedures can be facilitated, accordingly, the surgical time can be shortened, and surgical treatment effects and the survival quality of patients can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a memory alloy rib bone plate. Background technique [0002] Human ribs are bones used to protect the lungs, heart, liver and other organs, and are the framework of the entire chest cavity. There are many patients with rib fractures due to accidents, and the fractures will bring great pain and inconvenience to the patients, especially the posterior rib fractures, because the shape of the posterior rib is different from the shape of the front rib, and general-purpose equipment will cause malunion of the posterior rib . Generally, the embracing metal bone plate is often used in the operation, and the bone plate is fixed on the broken rib through the embracing claws, and the bone plate is removed after the broken bone heals. Patent No. 201420635714.5 discloses an encircling metal bone plate, which includes: a main plate, a number of fixed claws symmetrically ar...

AI Technical Summary

Problems solved by technology

However, this bone plate has the following two problems: 1. It does not consider the physiological structure of human bones in structure. If the bone plate is fixed on the posterior rib, the encircling claws will not be in place, and only screws are used to fix the connection, resulting in bone loss. Non-healing or malunion and increased risk of product breakage

2. The bone structure of the human rib bone is not considered. If the bone plate is fixed with screws, removing the screws after the affected bone heals will cause secondary damage to the bone
