Combined anatomical titanium mesh fusion cage

Abstract

The invention discloses a combined anatomical titanium mesh fusion cage, relates to the technical field of medical instruments, and solves the problems that most of common traditional titanium meshesare temporarily trimmed and formed in an operation, so that the end surfaces of the trimmed titanium meshes are sharp, local stress concentration occurs easily, the implanted titanium meshes is liableto directly puncture a connected end plate, and the surface of the end plate is sunken. According to the key points of the technical scheme, the fusion cage comprises a titanium cage main body used for being filled with autologous healthy sclerotin; a fusion through hole is formed in the circumferential side wall of the titanium cage main body; a reinforcing connecting ring is inserted into the end part of the titanium cage main body in the axial direction of the titanium cage main body; the end surface, deviating from the titanium cage main body, of the reinforcing connecting ring inclines to the cross section of the titanium cage main body; and anti-skid teeth are evenly distributed on the end surface, deviating from the titanium cage main body, of the reinforcing connecting ring. The fusion cage has the characteristics of being simple to operate and convenient to use in the operation, and the titanium cage main body does not need to be cut in the operation, so that operation time is greatly shortened and pain of a patient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a combined anatomical titanium mesh fusion device. Background technique [0002] With the changes in human living habits and styles, spinal fractures, tumors, infections and degenerative diseases related to spinal diseases frequently occur. For the treatment of the above diseases, although a large number of new technologies and methods are constantly emerging, for patients with more serious conditions, the choice of treatment is still biased towards surgical treatment. In the surgical reconstruction of spinal disorders, whether it is an anterior or posterior approach, it is necessary to reconstruct the vertebral body of the surgical segment after resection of the diseased vertebral body. The reconstruction and fixation devices of traditional surgery were abandoned due to many postoperative complications, and now most of them are replaced by anterior plate / posterior screw...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the traditional titanium meshes used clinically are temporarily trimmed and shaped during surgery. Therefore, the end faces of the trimmed titanium meshes are sharp, and local stress concentration is very easy to occur, resulting in the implanted titanium meshes easily directly piercing the connected terminals. Second, the end face of the traditional titanium mesh after temporary pruning is difficult to match the shape of the adjacent upper and lower endplates, reducing the contact surface of the bone graft, which will seriously affect the bone fusion; Thirdly, the traditional titanium mesh lacks matching locking tools during use, making it difficult to accurately move the titanium mesh to the correct position during implantation
