Description

technical field

[0001] The invention relates to the field of medical orthopedic repair and fixation operations, in particular to a medical bone fixation method and a fixation nail thereof. technical background

[0002] After the bones of the human body are broken due to various reasons, during surgical treatment, the bones are first reset, the two sections are combined, and then fixed with orthopedic fixation equipment. In terms of fixation, external fixation or internal fixation is used according to the specific conditions of the fracture. In terms of internal fixation, at present, steel plates and screws or Kirschner wires are used to internally fix the two broken ends of the bone. This technique of connecting with steel plates and fixing with screws has the following problems: the firmness of screw fixing depends on the thickness, density and resistance of the cortical bone of the connected bone. , Orbital bone and cancellous bone, due to their small thickness and resis...
