Problems solved by technology

[0002] Proximal tibial fracture is a common fracture, and its incidence rate is about 2.5% of all fractures in the whole body. It is more common in young adults with high-energy trauma and elderly fractures with loose fractures. The purpose of treatment is to restore the function of the shoulder joint to the maximum extent. The healing of conservative treatment is often unsatisfactory, and the previous internal fixation technology is difficult to achieve strong stability so that the shoulder joint can perform early and safe functional exercises, especially for comminuted fractures of the proximal humerus. There are many options and controversies in the treatment

Abstract

The invention discloses a tibia bone fracture plate of medical equipment for an orthopedic surgery. The tibia bone fracture plate comprises a bone plate body which is in the shape of Y, wherein the bone plate body comprises an attachment surface contacting with the surface of the tibia bone, and a bone plate body installation surface opposite to the attachment surface; installing through holes are formed in the bone fracture plate, the attachment surface is a titanium nitride ceramic material layer, and the installation surface is a titanium oxide ceramic material layer, and the surface treatment process of pickling and passivation is performed on the titanium alloy of the ingredient, and thus dark spots on any surface are avoided from occurrence and the prepared surface is clean and tidy; chemical agents composed of a specific pickling solution and a passivation solution are used, so that the period of surface treatment can be greatly saved and the surface treatment effect is very good.
