Description of the invention: [Technical field to which the invention pertains] Cheng 2: There is an artificial bone, especially an artificial bone in which a porous tissue is formed inside. [Prior Art] Only in the middle: 2: 'In the human bone road, the bones of the two bones 1 neck u (Figure = with the function of the active swing, but also bear the weight of the upper body = people walked accidentally fell and hips fierce When Lida was hit, it was either from ancient times 4;;, or because of a car accident, η fractured, and often Λ 'usually caused the bones and neck of the femur 1 elderly ^ and caused the injured to stand and walk. In the middle, the loss of bone is becoming more fragile, and the femur is more cramped. p 11 is the part with greater force. Pa 0g 1 mouth, this often occurs in the neck of the neck. The ▲ tube part of the blood supply to the femur 1 It is through the bones of the bones, and it suffers from (4) chasing, and it is easy to cause the femurs and blood i... insufficient and necrosis, so that the replacement of the artificial femoral head 3 is required. The conventional human head 3 is realistic '4 and has _ The body part 3 inside the femur 1 and a bone neck 32 connecting the body part 3 = curved shape. The above-mentioned method of manufacturing the femoral head 3 is known as the appropriate long-slip treatment. : a round rod; then 'surface-smooth the 'Zinc alloy round rod' and then 'the titanium The alloy round bar is forged, and becomes a preformed embryo; then, the preformed Jiajin Jierun α is treated; then, the embryo is subjected to constant temperature forging of the ant, 5 1305722; finally, The cutting edge treatment is performed to remove the excess material, that is, the artificial femoral head 3. It should be noted that the artificial femoral head 3 obtained by the above forging needs to be subjected to surface grinding, turning, and partial roughening treatment. It can be directly applied to the human body. However, since the conventional artificial femoral head 3 uses a solid bar, and the strength of the titanium alloy itself is relatively high, the required forming stress is also relatively large, and a large force is required. Forging forming equipment. Furthermore, because of the artificial: the bone 3 is a solid structure, it requires a lot of materials at the beginning, especially for parts where the appearance is complicated, which makes the material difficult to flow, and more material needs to be distributed. In order to meet the requirements of the product, therefore, the consumption and waste of the material are also caused, and the manufacturing cost is increased. [Invention] Therefore, the object of the present invention is to provide a The artificial bone with porous tissue can simulate the internal state of the real bone and can reduce the weight 'to reduce the material cost. 疋, the artificial bone with porous tissue of the present invention comprises a hollow shape and the ends thereof are closed. a bone-shaped tube, and a porous tissue that is housed and fixed to the bone tube: The effect of the present invention is to use a tubular bone tube, and the porous tissue fixed in the bone tube can be simulated The aspect of the real bone, at the same time, can also effectively reduce the weight, reduce the amount of material used, and reduce the material cost, while satisfying the required strength. [Embodiment] The foregoing and other technical contents related to the present invention , features and effects, in the detailed description of the application of the reference pattern in the 1305722 - complete. A 1 fixed vehicle, will be clearly presented. The preferred embodiment of the invention of the human bone head 4 having a porous structure includes a bone tube 4 and a porous tissue structure. In the preferred embodiment, the joint portion of the skin bone replaced by Hn_ 1 is taken as an example, but it may also be used to replace the shoulder portion of the shovel and the shovel. For the limit b, the bone tube 41 is in the middle of the shape of the king, and the ends thereof are closed. In the preferred embodiment, the bone type camp 41 aa is made of bismuth titanium alloy material, and one end is arc-shaped to facilitate insertion of the femur 1 (see Figure 。. In actual use, The bone tube 41 has a bending angle which is between 12 (r and 140°) depending on the applicable angle of the patient. The porous tissue 42 is housed and fixed in the bone tube 41 and has - a thin metal wire 421, and a metal clad material. The thin metal wire is in a winding and curved manner and is distributed in the inner space of the bone tube 41. In a preferred embodiment, the thin metal wire 421 is It is made of a titanium alloy material, and of course, it may be made of a material such as a brocade alloy, a steel alloy, a gold alloy, or a silver alloy. This embodiment is exemplified by placing a single thin metal wire 42 ι. Of course, it may be Two or more metal thin wires 42 are placed on the surface of the metal thin wire 421 and simultaneously bonded to the inner surface of the bone tube 41 (4) to form a porous structure. In a preferred embodiment, the metal cladding material 422 is made of a titanium alloy material. However, it may be a nickel alloy, a steel alloy, a gold alloy, or a silver alloy, etc. 7 l3 〇 5722. It is worth mentioning that 'the above-mentioned porous structure 42 is bonded to the metal thin wire 421 through the metal coating 422 The metal cladding material 422 is formed by electroforming. Of course, the porous metal structure 42 may be formed by sintering the metal powder, or may be placed in the bone camp 4 j first. The removable material is electroformed on the material, and finally the material is removed by heating or dissolving to form the porous structure 42. In other words, the type of porosity can be caused. The method of the present invention is not intended to limit the scope of the patent application of the present invention. In addition, since the metal thin wire 421 and the metal sheath 422 are both enclosed and enclosed in the bone tube Μ β, it does not interact with human cells. The direct contact, because the second, does not need to limit the materials of the two, that is, the metal thin wire 421 and the metal cladding material 422 may be other than the metal alloy, of course, other metals may be summarized above, and the invention has porosity. The artificial bone is woven with a hollow tubular bone tube 41, which reduces the weight, and can reduce the ^:output force singularity ' at the same time, with the metal thin wire 421 to be on; the surface of the metal thin wire 421 and the bone type - at 5 hai 422, with a metal cladding material constituting a straight straight f & 构成 constitutes a porous hunting similar to the sponge structure in the real bone, not only can the full strength of the artificial human head, but also reduce the weight and reduce the flaw of the material. Tian Dan ^ j to effectively ^, Li, and then reduce the cost of materials &#, so can indeed achieve the invention m the cost of the above, only 7 UL Rp ^, X month compared The best example is the application of the invention. In this case, the implementation of (4), that is, the scope of the field and the invention of the heart, the 4th effect of the invention is modified and modified. 8 1305722 is covered by the patent of the invention.
