Abstract

The invention provides a low-elastic modulus femoral stem which comprises a head, a neck part and a stem body. The low-elastic modulus femoral stem further comprises an elastic structure integrally formed in the stem body; the extending direction of the elastic structure is consistent with that of the stem body. The technical scheme of the invention effectively solves the problem of complicated manufacturing process of the low-elastic modulus femoral stem in the prior art.

Description

technical field [0001] The invention relates to the technical field of artificial joints in medical devices, in particular to a low elastic modulus femoral stem. Background technique [0002] At present, artificial hip replacement surgery has become a relatively common surgical operation in the medical field. It has allowed countless patients with terminal bone and joint diseases to return to normal life. In 2007, a review article published in the authoritative medical journal "Lancet" even called artificial hip replacement "the operation of the century" (The Operation of The Century). Artificial joint replacement refers to the use of metal, high molecular polyethylene, ceramics and other materials to make artificial joint prostheses according to the shape, structure and function of human joints, and implant them into the human body through surgical techniques to replace diseased joints and achieve relief. Joint pain, the purpose of restoring joint function. Artificial joi...
