The invention relates to artificial femoral head nested in femoral neck. The artificial femoral head is provided with a spherical articular surface and a femoral neck trepanning hole; the surface of the femoral neck trepanning hole is integrally molded with an inner three-dimensional net body; the surface of the inner three-dimensional net body is provided with a plurality of pores from outside to inside; the inside of the inner three-dimensional net body is provided with a transverse pore canal communicated with the partial or total pores; and the transverse pore canal of the inner three-dimensional net body is a single-layer pore canal or a multilayer pore canal. In operation, firstly, the necrotic part of the femoral head is removed; the femoral neck is remained as long as possible; then, a special surgical instrument is used for trimming the head end of the femoral neck into the shape inosculated with the femoral neck trepanning hole; and the artificial femoral head is sleeved at the head end of the femoral neck and pressed. After the artificial femoral head is mounted, when the articular surface needs an artificial hip joint renovation surgery after being worn for certain time, a product can be continuously used or an artificial femoral stem is implanted by a femoral neck resection according to the prior prevailing method; therefore, the artificial femoral head can increase more than one long-term renovation opportunity for patients.
Description
Technical field
The present invention relates to a kind of artificial thigh bone that is nested in neck of femur.
Background technology
Femur head necrosis is a kind of common orthopaedic disease, what adopt substantially when carrying out hip replacement surgery at present is from greater trochanter to lesser trochanter under the neat undercut with the femoral head of necrosis and neck of femur, implantable artificial femoral stem and manual acetabulum and femoral head then, the defective of this way is to have abandoned the neck of femur that major part still is in intact health status, has lost simultaneously to keep the complete chance of near end of thighbone in the future when doing revision procedure.
Summary of the invention
The purpose of this invention is to provide a kind of artificial thigh bone that is nested in neck of femur that can keep healthy neck of femur.
For achieving the above object, the present invention takes following design:
A kind of artificial thigh bone that is nested in neck of femur, it is characterized in that, it has spherical joint face and neck of femur trepanning, three-dimensional dictyosome in described neck of femur cover hole surface is formed with, the surface of three-dimensional dictyosome has most by table hole inwards in described, three-dimensional dictyosome inside has the horizontal duct in connected component or whole holes in described, and the horizontal duct of described interior three-dimensional dictyosome is monolayer duct or multilamellar duct.
Described neck of femur trepanning bottom has protruded out handle in the column marrow, the surface of handle is formed with outer three-dimensional dictyosome in the described marrow, the surface of described outer three-dimensional dictyosome has most by table hole inwards, described outer three-dimensional dictyosome inside has the horizontal duct in connected component or whole holes, and the horizontal duct of described outer three-dimensional dictyosome is monolayer duct or multilamellar duct.
Described outer three-dimensional dictyosome is arranged in the whole surface or the local surfaces of handle in the described marrow.
