Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a cover-protected intervertebral bone grafting kit. Background Art

[0002] A bone graft funnel is a tool used in bone grafting surgery to direct bone material into the grafting site. It is usually a conical metal funnel with a small opening at the top and a larger opening at the bottom. When used, the doctor will inject the bone graft material through the small opening at the top and then transfer it to the surgical site through the large opening at the bottom. Bone graft funnels are very common in orthopedic surgery because they ensure that the bone graft material is accurately guided into place and can help maximize the use of the provided bone marrow.

[0003] However, blood may splash out of the intervertebral space when the hammer is used to strike. When facing patients with infectious diseases, the splashed blood may cause infection to medical staff. At the same time, the blood splashes out of the wound and then falls back, which may bring a certain risk of contamination to the wound. In addition, bone grafting tools need to be replaced during bone grafting surgery. When replacing tools, the bone grafting tools need to be loaded into the bone grafting funnel again. Waiting is required while the bone grafting tools are reloaded, which may affect the implantation efficiency. Therefore, the present application provides a covered anti-splash intervertebral bone grafting kit to meet the needs. Utility Model Content
