Pelvic tamponade prosthesis

Abstract

The invention provides a pelvic filling prosthesis, wherein the prosthesis is integrally formed and arranged in a stereoscopic net shape, the stereoscopic net shape outer surface of the prosthesis isa curved surface shape, the curved surface shape adopts a copying design of an anatomical structure, and the prosthesis comprises an acetabular outer cup, an iliac bone connection part, a pubic bone connection part and an ischium connection part; and the prosthesis comprises an acetabular outer cup, an iliac bone connection part and an ischium connection part. An iliac bone connection part, a pubic bone connection part and an ischium connection part are arrange on that periphery of the acetabular outer cup, the out end of the iliac bone connection part is connected with the iliac bone cuttingsurface of the pelvis, the outer end of the pubic bone connection part is connecte with the pubic bone cutting surface of the pelvis, and the outer end of the ischium connection part is connected withthe ischium cutting surface of the pelvis. The prosthesis of the invention can realize free cutting, plasticity, convenient use and simple operation, and greatly reduces the difficulty of operation.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a pelvic filling prosthesis. Background technique [0002] The treatment of pelvic tumors has always been a major challenge for orthopedic surgeons, because of the long operation time, extensive dissection, heavy bleeding, high risk, and easy damage to nerves, large blood vessels and pelvic organs. After resection of pelvic ring or periacetabular tumors, often cause Large-scale bone defects, many intraoperative and postoperative complications, severe cases can be life-threatening. At present, according to the tumor destruction, its artificial prosthesis reconstruction techniques mainly include: tumor bone inactivation + artificial total hip replacement for pelvis reconstruction, allogeneic bone hemipelvis transplantation + artificial total hip replacement, artificial hemipelvis replacement, saddle Prosthetic replacement, or even total iliac crest replacement; replace...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the technical problem that surgeons perform osteotomy with prostheses according to pelvic tumor surgery, the present invention provides a pelvic bone filling prosthesis, which does not require more precise osteotomy on the patient, and the tumor site It can be removed; the present invention is a mesh-like prosthesis, which can be freely cut and plasticized according to the shape of the bone defect after tumor removal. The prosthesis is easy to use and easy to operate, greatly reducing the difficulty of surgery
