Problems solved by technology

[0003] Although the existing iliac wing prosthesis needs to be knocked into during installation, the surface has a bone trabecular network structure, which cannot bear too much force. Late stability; in addition, the spherical screw that enters the nail channel when driving is a hollow screw, which will reduce the strength of the screw, which is easy to break and difficult to screw in

Abstract

The invention provides an easy-to-mount iliac wing filling block, and the filling block comprises a filling block body and a knocking rod adaptively connected with the filling block body; a knocking area is arranged on the filling block body, and at least one first knocking groove is formed in the knocking area; and one end of the knocking rod is provided with an insertion column which is in insertion fit with the first knocking groove. The filling block has the advantages that the structural design of the knocking area and the knocking groove in the knocking area is matched with the structural design of the knocking bar, so that normal bone ingrowth and soft tissue crawling are not affected while the bone trabecula structure on the surface of the filling block body is protected.

Description

technical field [0001] The invention relates to the technical field of medical prosthesis, in particular to an easy-to-install iliac wing filling block. Background technique [0002] The body of the ilium is thick, forming the upper 2 / 5 of the acetabulum, and the wing of the ilium is a broad bone plate above the body, and the middle part is thinner. Its upper edge is hypertrophic and called the iliac crest. The front end of the iliac crest is the anterior superior iliac spine, 5-7cm behind the anterior superior iliac spine, and the junction of the anterior and middle 1 / 3 of the iliac crest protrudes outward, which is called the iliac tubercle. Both the anterior superior iliac spine and the iliac tubercle are important bony sign. Because the bone quality of the ilium is cancellous bone, and the bone mass is relatively large, part of the ilium is often taken as a material for human bone transplantation in clinical medical operations. , Tumor, nonunion, bone trauma, etc.; ...
