The present invention relates to the technical field of medical instruments, and in particular, to a laminectomy punch. The laminectomy punch includes a main body provided with a slide rail, a slide bar connected to the main body and a movable handle, where a cutting edge is disposed at the front end of the main body, and the movable handle abuts against the slide bar and can push the slide bar to move along the slide rail, and the laminectomy punch also includes a locking structure arranged on the main body and used to switch a working state or a disassembled state of the laminectomy punch; the locking structure includes a first state and a second state; when the locking structure is in the first state, the movable handle keeps abutting against the slide bar under the limiting action of the locking structure, and the slide bar can move normally along the slide rail, in which case the laminectomy punch is in the working state; and when the locking structure is in the second state, the movable handle can move downwards, the front end of the slide bar lifts up and is separated from the movable handle, the slide bar is away from the slide rail, in which case the laminectomy punch is in the disassembled state. The laminectomy punch of the present invention is easy to disassemble, clean and disinfect, and can be cleaned without being disassembled into components, thereby solving the problem that components are easy to lose.
