Abstract

The invention provides a femoral stem prosthesis and a manufacturing method thereof, and relates to the technical field of medical prosthesis to solve the technical problems that existing metal femoral stems loosen, yield and break easily. The femoral stem prosthesis is produced by laying multiple carbon fiber layers soaked by PEEK slurry; each carbon fiber layer comprises multiple long carbon fibers, and the direction of the long carbon fibers in the femoral stem prosthesis is identical with that of bone fiber. The manufacturing method comprises the steps as follows: knitting the long carbonfibers into the carbon fiber layers; soaking the carbon fiber layers in the PEEK slurry doped with short carbon fibers; laying the multiple carbon fiber layers in a mold layer by layer; curing the multiple carbon fiber layers by the mold. The technical scheme can prevent the femoral stem prosthesis from loosening, so that the femoral stem prosthesis has the characteristic of anisotropy, can bear loads in multiple directions and cannot yield or break easily, and the service life of the femoral stem prosthesis is prolonged.

Description

technical field [0001] The invention relates to the technical field of medical prosthesis, in particular to a femoral stem prosthesis and a manufacturing method thereof. Background technique [0002] A prosthesis is called a prosthesis in medicine, and it is a medical device that replaces a certain limb, organ or tissue of the human body. In the field of femoral stem prosthesis, metal materials are mostly used, but because the elastic modulus of metal is generally much larger than that of human bones, stress shielding is prone to occur, and the femoral stem bears more load, resulting in loosening of the prosthesis. In addition, metal materials are isotropic materials, which have no advantages when bearing obviously directional loads, and usually cause fracture, yield, buckling, and instability. Contents of the invention [0003] The object of the present invention is to provide a femoral stem prosthesis and its manufacturing method, so as to solve the technical problems t...
