Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, the femoral head prosthesis of the present embodiment includes bulb 10, porous structure layer 20 and polymeric layer 30,
In, porous structure layer 20 is wrapped on the outer surface of bulb 10, and polymeric layer 30 is wrapped on the outer surface of porous structure layer 20.
The polymerizable material (such as polyurethane, polyvinyl alcohol gel, polylactic acid) with good wear performance can be used in polymeric layer 30
The surface of porous structure layer 20 is molded over by modes such as thermoplastic, injection moldings.
Using the technical solution of the present embodiment, polymer have with consistency and elasticity similar in human body natural's physiology cartilage,
Polymeric layer 30 is wrapped on the outer surface of porous structure layer 20 as joint-friction face, false in traditional hip joint instead of liner
Effect in body answers the portion size space to save liner the space occupied in traditional hip prosthesis
With on femoral head prosthesis.I.e. in similar acetabular bone space, the size of the present embodiment femoral head prosthesis is bigger, can obtain more
Big flexion angle and inward turning angle avoids femoral head abjection to receptor to reduce the risk that femoral head is deviate from from acetabular bone
Secondary injury caused by patient.
In the femoral head prosthesis of the present embodiment, bulb 10 is fine and close solid construction, can be connected and mention with femoral stem
For enough structural supports, polymeric layer 30 is molded on porous structure layer 20 by modes such as injection molding or thermoplastics, polymeric material
