Abstract

The application discloses an osteotome for forming a spine fusion machine transplanting channel in a spine fusion operation, and relates to the technical field of medical apparatuses. The osteotome comprises a handle lever and an osteotome head arranged at one end of the handle lever, wherein the osteotome head forms a cylinder structure of which one end is opened; and an annular cutting edge is arranged at the opening end of the osteotome head, so that the transplanting channel can be formed in one time. According to the osteotome disclosed by the invention, in the spine fusion operation, anupper endplate cartilage surface, a lower endplate cartilage surface and an intervertebral disk can be cut in a quick forming manner, so that the operation efficiency is improved, and a complete spinefusion machine transplanting channel is formed.

Description

technical field [0001] The present application relates to the technical field of medical instruments, in particular, to an osteotome. Background technique [0002] Spinal fusion is a surgical procedure whose purpose is to join or fuse two or more vertebrae. In spinal fusion, it is necessary to effectively remove the intervertebral disc and remove the cartilage surface and nucleus pulposus tissue of the upper and lower vertebral body endplates, so that the bony surface of the upper and lower vertebral body endplates is exposed, so that the bone tissue can grow well after the fusion cage is implanted. fusion. [0003] At present, in spinal fusion surgery, the upper and lower endplates are generally treated by reamer twisting and scraper scraping the upper and lower vertebral endplates. It takes a lot of time to repeatedly process the upper and lower endplates, usually more than half an hour. It is time-consuming and labor-intensive, and it is very easy to cause the risk of a...
