Abstract

The invention discloses a high-strength adhesive for treating fracture. The adhesive comprises 100 to 300 milligrams of artificial protein A, 200 to 400 milligrams of protocollagen, 50 to 200 milligrams of biological zymogen, 100 to 500 milligrams of biological active calcium, 100 to 500 milligrams of polyglycolic acid, 100 to 400 milligrams of polylactic acid, and 10 to 50 ml of distilled water. A bone repair material of the invention has high biocompatibility and bone conduction property and can also be used for carrying out internal fixation of fracture and treatment for bone defect reconstruction in an injection mode.

Description

technical field

[0001] The present invention relates to a high-strength adhesive for treating fractures. Background technique

[0002] Bone cement is a kind of bone repair material that is easy to operate in clinical surgery, can be shaped arbitrarily and solidifies itself like cement, and has a wide range of applications in bone repair and other fields. One material currently available as a bone cement is polymethyl methacrylate (PMMA), which presents major problems with biocompatibility due to its composition being completely different from natural bone tissue. Although the traditional inorganic calcium phosphate bone cement has good biocompatibility and high bioactivity, its mechanical strength is too low, its compressive strength is low, its tensile strength is low, its brittleness is high, and its elastic modulus is greatly high. in natural bone. In addition, its injectability is poor, and it cannot accurately fill and repair the place to be treated according to the d...
