Embodiment Construction

[0014] Such as figure 2 The material of the bone fusion nail of the present invention is titanium alloy. 1 The shape of the bone nail is designed as a curved nail body according to the original shape of the sternum rib. 2 The nail body is made into a highly imitative human bone trabecular structure through a high-end technical equipment. The whole is an irregular transparent void mechanism. 3 Both ends of the bone nail are pointed. 4. There are 3-1MM segments of thread under the pointed head of both ends of the bone nail, and the threads at both ends are in opposite directions.

Abstract

The invention discloses a sacralization bone screw. An arc-shaped screw body is designed according to the original shape of a breast rib, so that the sacralization bone screw is fitted with the original shape of the breast rib. The screw body is manufactured into a bone trabecula lattice structure highly simulating a human skeleton through high-end technical equipment so as to induce bone ingrowth very good, and therefore, the screw and the bone are fused to form a unified integral skeleton. Both ends of the bone screw are respectively designed to be tips, and by such a design, two fracture surfaces of the broken bone can be conveniently set, and therefore, a better traction reduction and fixation effect is achieved. By reverse threads of 3-1mm below the tips at both ends, an implantation way during a surgery process can be changed into screwing in from complete driving in, and therefore, the surgery flexibility is greatly improved.

Description

technical field [0001] The invention relates to a surgical implant for sternal rib fracture, which mainly refers to a bone fusion nail that can be connected and fixed after the sternal rib fracture to form bone ingrowth Background technique [0002] Bone nails are commonly used bone implants in orthopedic surgery and have a wide range of applications. It is mainly used for reduction and fixation of bone fractures, such as figure 1 As shown, the shape is a metal round rod, one end is a pointed end and the other end is a flat head. Although existing bone nail models and specifications are many. But there is no special bone nail for sternal rib fracture (fracture). And none of the existing bone nails can form bone ingrowth and really achieve fusion with the bone. [0003] How to provide doctors with a professional bone nail for sternal rib fracture (fracture) and really capable of bone ingrowth is a problem to be solved at present. Contents of the invention [0004] The ...
