Technical Field
The utility model relates to the technical field of medical equipment, in particular to degradable magnesium alloy coaptation board.
Background
In the orthopedic medical materials, the traditional metal materials such as titanium alloy, stainless steel and the like have been widely used clinically, but also show obvious application limitations. For example, the elastic modulus of titanium alloy is tens of times higher than that of conventional natural bone, and the resulting "stress shielding effect" can affect bone healing and stability of the implant material. Other metal implant materials such as stainless steel and cobalt-based alloy release some metal ions harmful to organisms, and the metal ions are dissolved into body fluid through corrosion or abrasion to cause inflammatory reaction. In addition, the medical implant material belongs to a biological inert material, and when the medical implant material is used for fixing damaged parts such as bones and joints, secondary operation removal is needed after tissues are healed, so that secondary damage is caused to a patient. Therefore, new bone plates and screws made of biodegradable bone fixation materials are in the future.
