Embodiment Construction

[0013] The technical solution of the present invention will be described in detail below through specific examples.

[0014] An internal fixation device for fractures, comprising a fixation plate and bone nails pierced through the fixation plate. Such as figure 1 As shown, the fixing plate is made of titanium alloy steel plate 1, the surface of the titanium alloy steel plate 1 is sprayed with peek coating 2, the bone nail is made of titanium metal material, and the surface of the bone nail is also sprayed with peek coating.

[0015] Titanium has excellent corrosion resistance, elastic modulus close to natural bone, and excellent biocompatibility. Medical-grade peek has high strength and low dissolution characteristics, and has good compatibility with the human body. The fracture internal fixation device of the present invention maximizes the advantages and avoids the disadvantages of the characteristics of titanium metal and peek material. Surface treatment technologies such...

Abstract

The invention provides an internal fracture fixation device. The internal fracture fixation device comprises a fixing plate; a titanium alloy steel plate is adopted as the fixing plate; and a peek coating is sprayed on the surface of the titanium alloy steel plate. The internal fracture fixation device mainly enhances advantages and avoids disadvantages of the characteristics of titanium metal and peek materials, has the effects of good strength, corrosion resistance and adhesion prevention, can completely eradicate pain caused by adhesion, enables extraction to be smoother in a secondary operation, and reduces tissue damage.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a fracture internal fixation device. Background technique [0002] In internal fixation of fractures, steel plates and bone nails are needed to connect the two ends of the fracture. This device has a long history of clinical application, with definite curative effect and mature technology. As the dosage increases year by year, it also exposes the problem of easy adhesion to muscles, ligaments, and bone tissues during use, causing pain to patients, and the second operation must be forcibly peeled off with a scalpel due to adhesions, causing greater tissue damage. . [0003] Polyether ether ketone (peek) resin is a plastic with high strength and high fracture toughness, and peek material has the advantages of good biocompatibility, mechanical properties close to human cortical bone, high temperature resistance, self-lubrication, and corrosion resistance. It is used c...
