Sliding rod type lumbar hyperosteogeny grinding device

Abstract

The invention discloses a sliding rod type lumbar hyperosteogeny grinding device, which comprises a sleeve, wherein a sliding rod, which is in a length direction of the sleeve, is fixed to the interior of the sleeve; a grinding motor, which is capable of moving along the sliding rod, is arranged on the sliding rod; a holding rod is fixed to the top of the grinding motor; the holding rod extends from the top of the sleeve; a hollow main shaft is arranged in the grinding motor; a grinding disc is fixed to the tail end of the main shaft; a plurality of grinding tapers are uniformly distributed onthe lower surface of the grinding disc; a supporting rod is inserted into the main shaft; the bottom of the supporting rod is of a conical structure; a cushion spring is connected between the supporting rod and the main shaft; an exhaust pipe is connected to the sleeve wall of the bottom of the sleeve; and an exhaust device is connected to the tail end of the exhaust pipe. The grinding device provided by the invention has the beneficial effects that (1) the device is simple in structure, (2) the device is capable of conveniently grinding bumps, and the device is clean and sanitary, (3) sealing performance of the sleeve is improved, (4) the holding rod can be held by medical personnel more easily, and (5) the sleeve can be grabbed easily.

Description

technical field [0001] The invention relates to a medical instrument for orthopedics, in particular to a sliding bar type lumbar hyperosteogeny grinding device. Background technique [0002] At present, in medical practice, for patients with herniated lumbar intervertebral disc, grinding is generally used to grind the protruding hyperplasia part. However, the existing grinding device has a complex structure, and when grinding, the cushioning performance is not sufficient. It is not good, so it is easy to damage the normal lumbar spine mechanism, and cannot fully meet the needs of patients. Contents of the invention [0003] The problem to be solved by the present invention is to provide a sliding rod type lumbar hyperosteogeny grinding device which has a simple structure, can automatically adjust the grinding force, has a good grinding effect, and can absorb the debris generated after grinding in real time. [0004] In order to solve the above-mentioned technical problems...
