Problems solved by technology

[0002] The humeral shaft is one of the common sites of primary malignant tumors of bone and soft tissue. In recent decades, limb salvage surgery has made great progress in the surgical treatment of nausea tumors in this area. Artificial segmental tumor backbone prosthesis, That is, the humeral prosthesis has been applied and developed in limb salvage reconstruction after extensive resection of humeral shaft tumors. However, there are still many defects after implantation of the existing humeral prosthesis. problems, or the trauma area of ​​the prosthesis is larger during the extension process, etc.

Abstract

The invention provides an extendable humerus prosthesis. The extendable humerus prosthesis comprises a humerus upper end body and a broach prosthesis connected with the humerus upper end body in a sleeving mode. A strip-shaped fixing groove is formed in the upper portion of the broach prosthesis in the length direction of the broach prosthesis, a pin hole is formed in the lower portion of the humerus upper end body, and a fixing pin is sequentially inserted into the pin hole and the strip-shaped fixing groove so as to connect and fix the humerus upper end body and the broach prosthesis. The prosthesis has the advantages that the overall length of the prosthesis can be adjusted by adjusting the adjusting screw rod, the prosthesis is prevented from being replaced for multiple times in the growth process of a child patient, and meanwhile the risk can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an extendable humeral prosthesis. Background technique [0002] The humeral shaft is one of the common sites of primary malignant tumors of bone and soft tissue. In recent decades, limb salvage surgery has made great progress in the surgical treatment of nausea tumors in this area. Artificial segmental tumor backbone prosthesis, That is, the humeral prosthesis has been applied and developed in limb-salvage reconstruction after extensive resection of humeral shaft tumors. However, there are still many defects after implantation of the existing humeral prosthesis. problems, or the prosthesis has a larger trauma area during the prosthesis extension process. Contents of the invention [0003] The present invention provides an extendable humeral prosthesis, aiming at at least overcoming one of the above-mentioned technical defects. [0004] In order to realize the fore...
