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

Disclosed is an orthopaedic medical instrument tibia bone fracture plate. The orthopaedic medical instrument tibia bone fracture plate comprises a bone fracture plate body, the bone fracture plate body is T-shaped, the bone fracture plate body is provided with an attachment surface 1 in contact with the surface of a tibia and a bone fracture plate body installation surface 2 opposite to the attachment surface 1, the bone fracture plate is provided with installation through holes 3, the surface of the attachment surface 1 is a zirconium oxide system ceramic material layer, the surface of the installation surface 2 is a titanium carbide system ceramic material layer, and the inner surfaces of the installation through holes 3 are chrome oxide system ceramic material layers. The orthopaedic medical instrument tibia bone fracture plate has the following advantages: 1, through selection of a titanium alloy material and the T-shaped structure of the bone fracture plate, the bone fracture plate is enabled to have necessary high strength; and 2, surface processing technologies such as acidwashing and passivation are preformed on a titanium alloy of such components so that the problems of block spots on any surfaces and the like are avoided, and an obtained surface is neat.

Description

technical field [0001] The invention relates to a tibial bone plate of an orthopedic medical device, which belongs to the technical field of medical devices. Background technique [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 for the treatment. Contents of the invention [0003] The present invention aims at the above problems and proposes an orthopedic medical device tibial ...
