Metal hip joint combined handle

Abstract

The invention discloses a metal hip-joint combination handle including a handle body of a femoral bone handle, a neck body of the femoral bone handle, a near-end lining of the femoral bone handle, positioning pins and fixing bolts. With functional and physical design of each part of the metal hip-joint combination handle, the data of the near-end lining of the femoral bone handle is introduced into an electron beam melting and molding device, the titanium alloy power within the device is scanned, melted and molded into a conic cylinder body with intensity and elasticity similar to those of the biological cancellous bone by means of electron beam, the handle body part and the neck body part of the femoral bone handle are manufactured by precise forging[w2] or machine work, then the handle body of the femoral bone handle, the neck body of the femoral bone handle and the near-end lining of the femoral bone handle are serially assembled as a whole through positioning pins and fixing bolts, thus the metal hip-joint combination handle is configured. The combination handle has advantages of porous structure growing within cells, excellent dynamic and biological performance similar to those of human bones, high friction coefficients, stable configuration, multi combination modes among parts, high anastomosis degree and better matching capability with human medulla ossium lumen, relieving pains, stabilizing arthrosis, straightening monstrosity, improving functions of joint, facilitating operation execution, long service life and popular application.

Description

Technical field [0001] The invention relates to the technical field of artificial bone material for medical bone transplantation and its preparation, in particular to a metal hip joint composite handle for medical bone replacement. Background technique [0002] At present, in the clinical treatment of medical trauma orthopedics and surgery, the treatment of advanced hip joint diseases such as femoral head necrosis, osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, congenital hip joint dysplasia, hip joint trauma and For post-traumatic arthritis and hip joint destruction caused by various reasons, hip replacement surgery is commonly used. The main principle of hip replacement surgery is to reconstruct the anatomical structure of the human hip joint by implanting the artificially manufactured hip joint into the body, and make it obtain normal mechanical properties to complete certain physiological functions. This achieves the purpose of relieving pain and improvin...
