Biomimetic artificial spine prosthesis with flange

Abstract

The present invention relates to the technical field of artificial prosthesis for medical treatment, and specifically refers to a bionic artificial spinal prosthesis with flanges; Both ends of the body are provided with threaded holes. The bionic prosthesis and the flange body are an integrated structure with micro-holes constructed by 3D printing technology. The lower end surface of the bionic prosthesis and the upper end surface of the flange body are respectively penetrated; the structure of the present invention is reasonable, the upper end of the bionic prosthesis has a flange body, and the contact surfaces between the two and the upper and lower vertebrae are microporous structures, which are conducive to bone cell proliferation and Bone fusion; the bottom support and reinforcement ring at the fusion end construct a metal bearing surface, improve the compressive strength and twist resistance of the bionic prosthesis through the support beam, and improve the stability and reliability of the prosthesis; the porous prosthesis constructed by 3D printing technology Bionic prostheses can effectively promote the growth of bone cells and promote the healing and recovery of diseased parts.

Description

technical field [0001] The invention relates to the technical field of medical artificial prosthesis, in particular to a bionic artificial spinal prosthesis with a flange. Background technique [0002] Spinal surgery is the cutting-edge field of orthopedic surgery, and a spinal resection is a common type of surgery in this category. The spinal canal of the spine contains the spinal cord, and the spine is surrounded by important blood vessels. During spinal surgery, the operation must be precise and correct to ensure the safety of the operation. Spine surgery often includes spinal tumor surgery, spinal deformity surgery, intervertebral disc disease and other operations. The process of surgical treatment often requires complete resection of the structure of the spinal lesion and implantation of the corresponding artificial prosthesis to maintain the integrity and stability of the spinal structure Sex, so as to achieve the healing and reconstruction of the diseased part.

AI Technical Summary

Problems solved by technology

[0003] Restricted by traditional manufacturing methods, most of the artificial prosthetic implants in the past were standard parts, and the batch manufacturing of these standard parts made these implants less complex and personalized, making it difficult to adapt to complex and Individualized Spine Reconstructive Surgery

After resection of complicated spinal lesions, implants with relatively high size, shape, and matching accuracy are required to replace the resected parts, and the replacement of artificial prosthesis implants after spinal resection in these special, complex, and individualized parts It is difficult to use standard parts
