Titanium alloy artificial finger joint

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a titanium alloy artificial finger joint which comprises a first knuckle prosthesis, a connecting seat is arranged at the top of the first knuckle prosthesis, a second knuckle prosthesis is arranged above the connecting seat, a mounting groove is formed in the spherical surface of the bottom of the second knuckle prosthesis, and the connecting seat is connected between the inner walls of the two sides of the mounting groove through a pin shaft. Two first insertion columns are arranged at the top of the second knuckle prosthesis, the first insertion columns and the second knuckle prosthesis are of an integrated structure, first insertion holes are formed in the tops of the first insertion columns, the bottoms of the first insertion holes penetrate through the second knuckle prosthesis, first internal threads are formed in the inner walls of the first insertion holes, and two second insertion columns which are symmetrically distributed at the two ends are arranged at the bottom of the first knuckle prosthesis; a second inserting hole is formed in the bottom of the second inserting column, and a second internal thread is formed in the second inserting hole. According to the invention, the firmness after fixation can be effectively improved through butt joint of the anti-falling columns and the corresponding holes in the phalanx and fixation through the screws.

AI Technical Summary

Benefits of technology

Titanum alloys have been used for making orthopedic implants due to their high resistance against corrosion compared to other metals such as stainless steel (SS). They also provide strong holding power during use without losing them overtime. However, they still require regular maintenance because there may come loose parts like bolts if worn out too much. To address these issues, some designs involve adding extra components called guards instead of lockings. These guards help keep the prosthetic joint secure while allowing movement through its own structure.

Problems solved by technology

This patents describes different ways that people may have their own symptoms when they experience muscle or tendon injuries in one area but still want to use artificial materials instead of natural ones like metal plates during treatment due to concerns about potential complications such as inflammations caused by these types of injury. Additionally, there exist other issues with current solutions including lack of durability over time, reduced functionality from reconstructed knee replacements made on metallic implants, etc., making them less likely to be successful than desired.
