Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to an illuminable vertebral lamina rongeur used for vertebral lamina decompression. Background Art

[0002] Vertebral rongeurs are mainly used in clinical surgery, especially neurosurgery, to bite and cut small bones and soft tissues.

[0003] At present, clinically used vertebral rib rongeurs have the following problems: the existing vertebral rib rongeurs with built-in collection usually use a micro-suction pump to cut the bone fragments into pieces and then extract them. This method causes the bone fragments to be driven by the airflow in the pipeline. Since the bone fragments are irregular in shape and sometimes have sharp corners, they are easy to get stuck in the internal pipeline, causing the surgical instrument to fail and the operation to be interrupted. The doctor needs to clean the stuck bone fragments. At the same time, the size of the collected bone fragments is not convenient for direct use, and the surface residue is troublesome to clean later. Therefore, the present application provides an illuminable vertebral rib rongeur for vertebral rib decompression to meet the demand. Summary of the invention
