Embodiment Construction

[0036] Please check Figure 1 to Figure 4 , the drug-carrying device 10 for the bone spicule implant 20, connected to the bone spicule implant 20. The drug-carrying device 10 includes a sleeve member 11 . The sleeve member 11 has an inner hole 12 and an annular portion 13 that surrounds the inner hole 12 and can be sleeved on the outside of the bone needle implant 20. The annular portion 13 is provided with a drug-loading cavity 14 that is separated from the inner hole 12. The drug cavity 14 runs through both ends of the annular portion 13 and has an opening 15 located on the outer wall of the annular portion 13 . The drug-loading cavity 14 contains drugs. According to requirements, the sleeve member 11 is also equipped with two seals, the two seals are detachably attached to the two ends of the ring part 13, and the seal and the ring part 13 are assembled together. The port of the drug-carrying cavity 14 located on the end face of the annular portion 13 is sealed. In this ...

Abstract

The inVention discloses a drug-loading deVice for a bone needle implant and a drug carrying method thereof. The drug-loading deVice is connected with the bone needle implant and comprises a sleeVe tube member, the sleeVe tube member is proVided with an inner hole and an annular part which can sleeVe the bone needle implant, the annular part is proVided with a drug-loading caVity which is separatedby the inner hole, the drug-loading caVity penetrates through two end faces of the annular part and is proVided with an opening located on the outer circumferential wall of the annular part, and drugs are loaded by the drug-loading caVity. The deVice has the adVantages that after the drugs are contained in the drug-loading deVice after drug loading is conducted, the drug loading deVice sleeVes the bone needle implant, during the using process, the growth of germs can be inhibited by the sustained releasing of the drugs through the opening to achieVe the purpose of preVenting needle path infection, the drug-loading problem on a percutem implant is solVed, and curing of a background technology can be eliminated.

Description

technical field [0001] The invention relates to the field of orthopedic surgical instruments, in particular to a drug-loading device and a drug-loading method for bone needle implants. Background technique [0002] Fractures can be treated with internal fixation or external fixation, while open fractures are generally treated with external fixation. The external fixation method is mainly composed of bone needles penetrating into the bone and connected with the external bracket. Under the protection of external fixation, other treatments can be performed, such as debridement in stages, soft tissue repair, such as skin grafting, anastomosis of blood vessels and nerves, etc. Because the spicules penetrating into the bone are placed far away from the fracture site, the tissues at the fracture site are not damaged, so the spicules and blood supply at the fracture site can be protected to the greatest extent, which is beneficial to bone healing. [0003] During the use of the bon...
