[0030] Further, one end of the negative pressure suction channel 2 away from the planing member 1 is connected with the negative pressure suction member. Thus, the nucleus pulposus debris after planing can be sucked and discharged by the negative pressure suction member, so as to improve the processing efficiency of the intervertebral disc. The nucleus pulposus debris after planing can be cleaned in time, so as to keep the visual field of the operator clear. Thus, the safety of the operation is ensured, and the operation efficiency is improved, and the operation time is shortened.

[0031] In a specific embodiment, the negative pressure suction member is a device capable of sucking the nucleus pulposus debris by negative pressure. Specifically, the negative pressure suction member can be a negative pressure suction device.
