Abstract: An implant being a stent is provided. The stent has a plurality of wire structures and a plurality of tube structures. The tube structures are formed on each one of the wire structures. Each one of the tube structures forms a cavity, one end of each one of the tube structures is connected to the wire structure, and another end forms an opening communicating with the cavity. Therefore, the openings formed on the implant communicate with the cavities, such that the medicine applied on the implant can flow into the cavities and not easily flow out via the openings.

Abstract: An implant being a stent is provided and has an outer surface and multiple cavities. Multiple openings are formed on the outer surface and the cavities communicate with the openings. The maximum latitudinal section area of each cavity is larger than the area of the opening. The latitudinal section of the cavity is parallel with the outer surface of the implant. Therefore, the openings formed on the implant communicate with the cavities, such that the medicine applied on the implant can flow into the cavities. Further, because the maximum latitudinal section of each cavity is larger than the corresponding opening, after flowing into the cavities, the medicine would not easily flow out via the openings.

Abstract: An artificial bone plate unit and an assembleable artificial bone plate are provided. The artificial bone plate unit includes a plate body, multiple connecting pins, connecting holes, drug cavities, and drug-releasing openings. The plate body has two main surfaces and a peripheral surface connected between the two main surfaces. The connecting pins and the connecting holes are formed on the plate body and arranged along the peripheral surface on the plate body. The connecting holes correspond in shape to the connecting pins. The drug cavities are formed in the artificial bone plate unit and are connected to the drug-releasing openings. The artificial bone plate units are connected using the connecting pins and the connecting holes to form the assembleable artificial bone plate. The assembleable artificial bone plate can be bent into the shape of a defect area of the skull, which saves material and time.
