Tibial prosthesis installation system and installation method

Abstract

The invention discloses a tibial prosthesis installation system and an installation method. The tibial prosthesis installation system comprises a mounting bracket and a tibial prosthesis, the mountingbracket comprises a frame body, the frame body is provided with a first arm, a second arm and a third arm, the first arm is provided with a prosthesis portion, the third arm is provided with a positioning portion, the second arm is provided with the prosthesis portion or the positioning portion, the tibial prosthesis includes a prosthesis body, the prosthesis body is provided with a first connecting portion on the left side and a second connecting portion on the right side, a third connecting portion is further disposed in the middle of the prosthesis body, the connecting surface of the firstconnecting portion, the second connecting portion and the third connecting portion is provided with protruding clamping teeth, the prosthesis body is further provided with at least three fixing holebrackets connected with the tibial prosthesis, the prosthesis portion is connected with the prosthesis body, and the positioning portion corresponds to a fixing hole. The method achieves tibial reconstruction installation and positioning through the tibial prosthesis installation system.

Description

technical field [0001] The invention relates to artificial prosthesis installation, in particular to a sacral prosthesis installation system and installation method. Background technique [0002] The sacrum is an important bone that connects the bones of the human body. It connects the spine of the upper body and the ilium of the lower body. It is an important bone that supports the human body. However, due to lesions such as tumors, a large and complete resection of the low-level metastatic tumors of the primary malignant tumor of the sacrum is adopted. As a result, the support strength of the sacrum is insufficient, so the sacrum needs to be reconstructed, and the installation and positioning accuracy of the reconstructed sacrum is high, but there is no corresponding installation and positioning system in the prior art. Contents of the invention [0003] The purpose of the present invention is to improve the shortcomings of the prior art, provide a sacral prosthesis inst...
