Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0028] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0029] Unless otherwise def...

Abstract

The invention provides a femoral stem prosthesis which is internally provided with a cavity, one end of the femoral stem prosthesis is provided with a communication hole communicated with the cavity,a porous structure is embedded in the outer side wall of the femoral stem prosthesis, and holes in the porous structure are communicated with the cavity. After the femoral stem prosthesis is insertedinto a femoral medullary cavity, blood and nutrient substances can enter the femoral stem prosthesis from the communicated holes and are exchanged with external human sclerotin through the porous structure so that circulation of blood and nutrient substances is realized, local tissue necrosis is avoided, bone ingrowth is facilitated, osteoporosis or dissolution around the prosthesis is avoided, and postoperative aseptic loosening and ostealgia caused by postoperative aseptic loosening are eliminated, meanwhile, human bones can grow into holes in the porous structure, so that the implantation stability of the femoral stem prosthesis is greatly improved, in addition, due to the fact that hollowing and topological optimization are conducted on multiple positions of the femoral stem prosthesis, light weight is achieved, and the advantage of being light in weight is achieved.

Description

technical field [0001] The invention relates to the technical field of artificial prosthesis, in particular to a femoral stem prosthesis. Background technique [0002] The human femur is one of the most important bones in the human body, and its main function is to support the trunk and pelvis of the human body. Under the stimulation of trauma, hormone drugs or congenital reasons, the hip joint is prone to necrosis, resulting in the loss of physiological function of the human hip joint, accompanied by pain and other symptoms. [0003] Artificial hip replacement is currently one of the most common and effective means of treating hip joint diseases. Artificial hip replacement refers to a method of implanting a femoral prosthesis into the human body through orthopedic replacement surgery to replace the human hip joint. Specifically, the femur The femoral head of the prosthesis is put into the acetabulum, and the femoral stem of the femoral prosthesis is inserted into the femor...
