Embodiment 1

[0052] It should be noted that the above-mentioned "the drug-carrying containers 20 on the same floor are arranged correspondingly to one drug-controlling chamber 11" refers to the drug-carrying containers 20 at the same height in the horizontal direction or within the range of an angle of 30 degrees to the horizontal direction. Corresponding to one drug control chamber 11.

[0053] like Figure 18 to Figure 21 As shown, when the prosthesis body 10 is bent by the force F, the drug control chamber 11 is compressed. Since the drug control chamber 11 includes a third arcuate surface 113 and a fourth arcuate surface 114 opposite to the opening of the third arcuate surface 113, the An annular opening is formed between the three arc surfaces 113 and the fourth arc surface 114, and the overflow hole 24 of the drug-carrying container 20 on the same layer among the plurality of drug-carrying containers 20 is located at the annular opening, and the medium in the drug-carrying chamber 11...

Abstract

The invention provides an implantable prosthesis, which comprises a prosthesis body, a fixing part, a fixing part and a fixing part, wherein the prosthesis body is provided with a mounting part; the medicine carrying container is fixedly mounted on the mounting part, the medicine carrying container is provided with a containing cavity for containing medicine, and an overflowing hole and a slow release hole which are communicated with the containing cavity are formed in the medicine carrying container; wherein a medicine control cavity with variable volume is arranged in the prosthesis body, the overflowing hole is communicated with the medicine control cavity, and the slow release hole is communicated with the outside of the prosthesis body. According to the technical scheme, the problem that in the prior art, due to long-time non-healing of bones, the bone fracture plate is broken or the artificial hip joint prosthesis is loosened is effectively solved, the medicine in the containing cavity can be one of anti-infection medicine, osteogenesis promoting medicine, anti-osteoporosis medicine and anti-tumor medicine, and therefore the medicine can be used for treating osteoporosis. A doctor can select according to the actual condition of a patient, so that the implanted prosthesis can provide help for corresponding treatment.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an implant prosthesis. Background technique [0002] Bone plate is the most commonly used internal fixation device for the treatment of fractures at home and abroad. So far, the use of bone plates to treat fractures has a history of more than 100 years. The treatment principle is to make an incision at the broken end of the fracture, place the bone plate so that the bone plate spans the fracture, and then fix the bone plate on both ends of the fracture with screws. end so that the bone at the fracture end can be effectively fixed. Therefore, the structure of the bone plate includes a body of the bone plate which is similar in shape to the surface of the bone, and the body is provided with screw holes for screw fixation. [0003] Existing bone plates are all used as physical fixation devices, and their functions are all to realize bridging and fixing of broken ends of fractures, s...
