Hereinafter, F) EtJ93 will be specifically explained based on an example shown in the drawings. In the first embodiment shown in FIG. 1, the matrix 1 is composed of a core material 2 made of ζ made by twisting titanium fibers and sintering them into a predetermined shape, and an artificial old material 3 covering the core material 2. The core material 2 is formed by mixing titanium fibers and carbon into a predetermined shape, and then burning off the carbon during sintering to obtain a porous structure. The artificial aggregate 3 is calcium hydrogen phosphate,
It is a fine powder made from calcium dihydrogen phosphate, animal bones such as cow bones, etc., and is coated on the core material 2 and sintered. This artificial aggregate 3 is also formed in a porous shape.

The entire surface of the base material 1 and the hollow portion 7 are coated and filled with collagen 8 to which mucopolysaccharide (for example, chondroitin), alginic acid, calcium, etc. are added. The method for this coating and filling is to put the base material 1 in a vacuum chamber, remove the air in the artificial aggregate 3 of the base + A1 and the pores of the core material 2 by suction, and then dissolve it in acetic acid f62&, citric acid solution, etc. The collagen 8 thus obtained may be supplied into a vacuum chamber for coating and filling. The collagen 8 penetrates into the pores of the artificial aggregate 3 and is strongly bonded to the base material 1.

In addition, the joint ball 4 is coated with collagen 8 to which mucopolysaccharide, calcium, etc. are added (these become cartilage tissue),
An artificial joint capsule 11 is formed that can contain a fluid 10 therein. In addition, it is preferable that the porosity of the base material 1 in the joint ball part 4 is increased, for example, from 15% to 20%, while the porosity of other parts is set to 10% or less.

Next, the operation of this embodiment will be explained. As shown in FIG. 1, the artificial bone (hip joint) of this embodiment has its connecting end 9 inserted into the bone marrow of a natural bone (lower part of the femur) a, and its joint ball 4 is inserted into the pelvis. It is used by being fitted into the glenoid fossa. As time passes after the artificial bone is transplanted into the human body, an artificial periosteum is formed due to the action of the Kola-Ken 8, and this combines with the natural bone a, and the artificial bone and the natural bone are connected at the connecting end 9. It is strongly connected to a.

In addition, a natural joint capsule made of collagen is formed between the joint ball part 4 and the glenoid fossa, and a gap is formed between the joint ball and the glenoid fossa, and it also functions as a shock absorber. Become. Furthermore, the above-mentioned phenomena in which bone marrow tissue is generated in the hollow part 7 by the action of the collagen 8 in the hollow part 7 are caused by the fact that the collagen 8 is mesodermal and is compatible with living organisms, especially mesodermal tissue, and capillaries are formed there. It has the property of being easily connected to the body, and once nutrients are supplied through the capillaries, it induces the collagen fibers of the living body and is suitable for forming natural periosteum tissue, medullary tissue, etc. It is caused by
