Personalized acetabular prosthesis

Abstract

The invention provides a personalized acetabular prosthesis. The personalized acetabular prosthesis comprises an acetabular cup body, an ischium fixing wing plate, an ilium limiting plate, a first screw channel and a trabecula structure. The ischium fixing wing plate, the ilium limiting plate and the first screw channel are all arranged on the acetabular cup body and connected to the outer wall ofthe acetabular cup body. The trabecula structure wraps the acetabular cup body and connected with the outer wall of the first screw channel, so that the trabecula structure is located between the acetabular cup body and remaining bones after osteotomy, and screws penetrate into the first screw channel to fix the acetabular cup body to an osteotomy face. The problems that complications such as looseness, screw breakage and joint dislocation are prone to occurring in the initial stage of prosthesis implantation are solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a customized acetabular prosthesis. Background technique [0002] The pelvis is one of the predilection sites for benign and malignant tumors. Pelvic tumors occur in deep locations, with complex anatomical structures and mild early symptoms that are difficult to detect. It is very easy to cause missed diagnosis and misdiagnosis. Therefore, the tumor volume is larger when it is clinically discovered, and the blood loss and complications during the operation are more, which makes the operation more difficult. [0003] The clinical treatment of pelvic tumors mostly adopts limb salvage method, that is, the tumor is resected en bloc along the safe margin. Due to the inconsistency of tumor location and size in each patient, the standardized acetabular prosthesis cannot meet the joint reconstruction requirements after tumor resection. It is prone to technical problems such as...

Problems solved by technology

It is very easy to cause missed diagnosis and misdiagnosis. Therefore, the tumor volume is larger when it is clinically discovered, and the blood loss and complications during the operation are more, which makes the operation more difficult.

[0003] The clinical treatment of pelvic tumors mostly adopts the limb salvage method, that is, the tumor is resected en bloc along the safe margin. Due to the inconsistency of tumor location and size in each patient, the standardized acetabular prosthesis cannot meet the joint reconstruction requirements after tumor resection. It is prone to technical problems such as unstable prosthesis implantation and damage to soft tissues and organs around the section; therefore, it is urgent to customize acetabular prosthesis to solve the above technical defects
