Embodiment 1
[0011] Embodiment 1: with reference to attached figure 1 , 2 , 3, 4, this carbonaceous artificial humeral head prosthesis is composed of a carbonaceous humeral head sphere 1 and a humeral head handle 2. The sphere of the humeral head is a hemisphere, and a cylindrical fixing groove 3 is formed on the bottom of the sphere of the humeral head along the axial direction, and a radial positioning groove 6-3 is formed on the fixing groove. The humeral head handle is composed of the upper cylindrical fixing column 4 and the humeral head handle rod 5 connecting the lower part. A fixing platform 7 is provided at the connection between the fixing column and the humeral head handle rod. The positioning on the fixing column and the fixing groove A radial positioning groove 6-4 is formed at a position corresponding to the groove 6-3. The section of the humeral head stem is circular, with an anti-rotation groove 8 longitudinally and an anti-loosening groove 9 transversely, and a pull-out ...
Embodiment 2
[0012] Embodiment 2: refer to Figure 5 , its structure is basically the same as that of Example 1, the sphere of the humeral head is a multi-hemispherical body, the fixing groove on the sphere of the humeral head deviates from the axis, so that the neck-shaft angle α is 140°, and the sphere of the humeral head has a suspension hole 12.
[0013] Among them, the carbon-titanium artificial humeral head prosthesis: Embodiment 1 is suitable for cases of simple humeral head articular surface injury and shoulder dysfunction; Embodiment 2 is suitable for comminuted fractures or lesions of the humeral head, such as tumors or tumor-like lesions. Carbon-carbon artificial humeral head prosthesis: suitable for a large range of comminuted fractures of the humeral head and neck or head and neck tumors or tumor-like lesions.
[0014] According to the characteristics of the humeral head of adults, the applicant of the present invention has made respectively carbon-titanium, carbon-carbon and ...
