Novel metal-ceramic femoral head with wear resistance and non-cracking and manufacturing method thereof

Abstract

The invention discloses a novel wear-resistant unruptured metal ceramic femoral head. The novel wear-resistant unruptured metal ceramic femoral head comprises a metal femora head main body (1) and an integrated metal structure part; the integrated metal structure part is arranged at the bottom of the metal ceramic femoral head main body (1) and forms the novel wear-resistant unruptured metal ceramic femoral head of an integrated structure with the metal ceramic femoral head main body (1). The invention further discloses a preparation method of the novel wear-resistant unruptured metal ceramic femoral head. According to the novel wear-resistant unruptured metal ceramic femoral head and a preparation method thereof, at least the quality, structure and performance of the ceramic femoral head can be greatly improved, and the wear-resistant and unruptured effect of the metal ceramic femoral head can be achieved.

Description

technical field [0001] The invention relates to a ceramic femoral head in the field of biomedical devices and a manufacturing method thereof, in particular to a new type of cermet femoral head which can greatly improve the quality, structure and performance of the ceramic femoral head, which is wear-resistant and non-cracking and its production method. Background technique [0002] The femoral head is the two bones that support the upper part of the body. The specific location is under the pelvis. There is an acetabulum on one side of the pelvis. The two femoral heads just fit with the acetabulum to support the upper body. The femur is the most important bone in the human body, and the femoral head is even more important. People's upright walking, activities, and labor all rely on the support of the femoral head, so the femoral head is also the most vulnerable part. After the femoral head is injured, the ceramic femoral head is an important material for artificial hip repla...

AI Technical Summary

Problems solved by technology

[0003] The ceramic femoral head in the prior art is easy to break, and its structure figure 1 As shown, it includes the ceramic femoral head conical hole 6, the small end of the conical hole 7, the bottom of the femoral head 8, and the main body of the traditional ceramic femoral head 9. The stress generated by the cooperation between the hole and the conical column of the neck, and the bottom of the femoral head receives the largest tension. When the patient walks, the impact force is generated due to falling, bumping, bumping, and punching, which increases the internal tensile stress, resulting in traditional ceramics. The femoral head is easily broken, so the patient has to replace the femoral head again, which not only increases the pain of the patient, but also increases the cost of treatment

[0004] Therefore, it is hoped to provide a new type of structural ceramic femoral head to overcome the cracking phenomenon caused by the unreasonable structure of the traditional ceramic femoral head
