Description
Technical field
The present invention relates to the hip replacement surgery implant, particularly a kind of damaged obturator of acetabular bone bone that is used for the damaged filling of bone.
Background technology
Continuous progress along with medical skill; a kind of common relatively surgical operation of artificial hip joint replacing operation becoming gradually; common way is to pack an acetabular cup prosthesis made from ultra high molecular polyethylene or metal and pottery into to substitute the function of compromised acetabular in hip joint acetabular bone side; but running into the acetabular bone side through regular meeting in art causes because of bone that a variety of causes caused is damaged on the bone bed that is fixed in patient's acetabular bone position that acetabular cup prosthesis can't be stable; generally need do autologous bone transplanting or allogenic bone transplantation this moment, and this can cause increases patient's misery; operating time prolongs; expense increase or the like problem.
Summary of the invention
The purpose of this invention is to provide and carry out the damaged filling of bone and fixing easily, and can use the bone cement damaged obturator of acetabular bone bone that is fixed in physiology acetabular bone position that the artificial hip joint acetabular component is firm.
For achieving the above object, the present invention takes following design:
The damaged obturator of acetabular bone bone is characterized in that, the damaged obturator of acetabular bone bone is the three-dimensional porous dictyosome that adopts medical metal or bioceramic to make, and the surface of this three-dimensional porous dictyosome and inside have most the ducts that are interconnected.
The damaged obturator of described acetabular bone bone in position is provided with the screw hole that is used for the damaged obturator of bone is fixed in the bone bed, and this screw hole can be one, also can be a plurality of.
Consider the heavy burden force-bearing situation that needs to fill the position, the surface and the inside of the damaged obturator of described acetabular bone bone are provided with reinforcement or stiffener.
The damaged obturator of described acetabular bone bone appropriate location is provided with the bone grafting hole that holds broken osseous granules of bone grafting or bone mud, broken osseous granules of this bone grafting or bone mud can be in operation by the osteotomy of necessity, bore operating process such as bone and obtain.
The damaged obturator of described acetabular bone bone surface all or the part have hydroxyapatite coating layer, this hydroxyapatite coating layer has the function of inducing the osteocyte growth.
The processing method of the damaged obturator of described acetabular bone bone is: adopt laser or high-power electron beam rapid shaping technique melt molding, also can bore with the processing on casting or rough forging of methods such as casting, spark machined, chemical attack, machine drilling cutting and mill out needed porous dictyosome.
Advantage of the present invention is:
1. the damaged obturator of this practical acetabular bone bone, the three-dimensional porous dictyosome structure that adopts medical metal or bioceramic to make, the surface of this three-dimensional porous dictyosome and inside have most the ducts that are interconnected, this three-dimensional porous dictyosome and sclerotin closely contact and help the growing into to obtain long-term stability of osteocyte, and the damaged obturator of acetabular bone bone contacts part owing to also exist a large amount of three-dimensional mesh with the manual acetabulum implant, thereby can coat by the infiltration of bone cement and obtain firm connection, prevent from effectively between manual acetabulum implant and the damaged filling of acetabular bone bone long-term loosening to take place.。
2. the damaged obturator of acetabular bone bone of the present invention, it comprises: damaged obturator of acetabular bone bone and the screw hole that is provided with in the damaged obturator of described bone appropriate location, the doctor can select as required suitably that the damaged obturator of acetabular bone bone of size and shape is placed in the damaged place of bone and is fixed on the bone bed to obtain stablizing in early days of implant with screw in the art.
3. consider the heavy burden force-bearing situation that needs to fill the position, the surface and the inside of the damaged obturator of described acetabular bone bone are provided with reinforcement or stiffener.
4. the damaged obturator of acetabular bone bone of the present invention in position is provided with the bone grafting hole that holds broken osseous granules of bone grafting or bone mud and is used to fill broken osseous granules from body or allosome, operation is implanted the back by the time the infiltration of outside osseous tissue is grown into three-dimensional mesh and with the bone grafting hole in the broken osseous granules of filling or bone mud fusion growth can reach after being integral and prevent that long-term effectively the damaged obturator of this acetabular bone bone from loosening effect taking place.
5. the damaged obturator of acetabular bone bone of the present invention, all surperficial or part has hydroxyapatite coating layer, and this hydroxyapatite coating layer has the function of inducing the osteocyte growth.
6, the damaged obturator of acetabular bone bone of the present invention, it uses medical metal or bioceramic to make, therefore it has good biocompatibility, the processing method of the damaged obturator of described acetabular bone bone is: adopt laser or high-power electron beam rapid shaping technique melt molding, also can bore with the processing on casting or rough forging of methods such as casting, spark machined, chemical attack, machine drilling cutting and mill out needed porous dictyosome.
