Abstract

The invention provides a vertebral prosthesis. The vertebral prosthesis comprises a main body structure, a plurality of first end plates which are connected to the first end of the main body structure in a replaceable mode, and a plurality of second end plates which are connected to the second end of the main body structure in a replaceable manner. The height of the main body structure can be adjusted so as to change the distance between the first end plates and the second end plates. According to the technical scheme, the problem that in the prior art, the end plates are poor in cooperation with a vertebral body of the human body, and then the implantation effect is further affected, is effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a vertebral body prosthesis. Background technique [0002] Vertebral primary tumors, partial localized metastatic tumors, severely comminuted vertebral fractures, and severe spinal bursts often require vertebral body resection or subtotal resection. The stability of the spine after vertebral resection will undoubtedly be destroyed, and reconstruction of the structure and function of the spine is a necessary condition for maintaining the normal biomechanical stability of the spine. [0003] At present, according to their structural differences, they can be divided into two types: fixed height type and adjustable height type. [0004] The so-called fixed-height artificial vertebral body is the simplest type, which only plays a certain role of support and fixation during the operation, represented by ordinary titanium cages, new titanium cages, and 3D printed titanium c...
