Abstract

The invention provides a centrum prosthesis which comprises a first centrum, a second centrum, a height adjusting component and a detection component. The first centrum is provided with a first mounting hole, the second centrum is provided with a second mounting hole, the first centrum and the second centrum are arranged at an interval, the height adjusting component is arranged between the firstcentrum and the second centrum, one end of the height adjusting component is penetratingly arranged in the first mounting hole and is in driving connection with the first centrum while the other end of the same is penetratingly arranged in the second mounting hole and is in driving connection with the second centrum, the detection component is electrically connected with the height adjusting component and used for detecting state parameters of the centrum prosthesis, and the height adjusting component adjusts the interval between the first centrum and the second centrum according to the stateparameters. Through the technical scheme, the problem that centrum prostheses cannot work normally after collapsing in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of prostheses, in particular to a vertebral body prosthesis. Background technique [0002] At present, more and more surgical treatments are used in the treatment of spinal diseases. By implanting vertebral body prosthesis in the patient's body, the vertebral body prosthesis can be used to support the adjacent vertebral bodies to restore the function of the spine and complete Repair of the spine. [0003] However, for older patients or patients with severe bone loss, due to the existence of osteoporosis in patients, the vertebral prosthesis is prone to collapse after surgery, and the vertebral prosthesis cannot work normally. Therefore, there is a problem in the prior art that the vertebral body prosthesis cannot work normally after it collapses. Contents of the invention [0004] The invention provides a vertebral body prosthesis to solve the problem in the prior art that the vertebral body prosthesis c...
