Abstract

The invention relates to the technical field of medical facility of surgical operation, and particularly relates to a minimally invasive bone grinding tool, which comprises a bone grinding cutter head and a transmission mechanism used for driving bone grinding tools. The bone grinding cutter is connected with one end of the transmission mechanism, and the other end of the transmission mechanism which is away from the bone grinding cutter is connected to a power device which is used for driving the transmission to carry on reciprocating motion. Through operating under surgery mirror, the minimally invasive bone grinding tool realizes the treatment of spinal canal stenosis through a power bone grinding tool, thus solving problems in prior art such as complication of the existing operation, long operating time and big harm brought to patients. Besides, the minimally invasive bone grinding tool can achieve the advantages of small wound surface, quick recovery speed, and low cost, thereby satisfying better the needs of the patients and reducing harm to a lower degree.

Description

technical field [0001] The invention relates to the technical field of surgical medical equipment, in particular to a minimally invasive bone grinding tool. Background technique [0002] Spinal stenosis is one of the common diseases in middle-aged and elderly patients. Spinal stenosis is caused by bone hyperplasia in the lumbar spine itself, which causes the spinal canal to become smaller and squeezes the nerves passing through it, causing pain, inability to bend the waist, and numbness of hands and feet. , walking with a limp, etc. Spinal canal dilation is one of the main operations in spinal surgery. Spinal canal dilation requires the use of professional surgical tools. [0003] In the prior art, the dilation of spinal canal stenosis is an open operation, which requires an incision of more than 10 centimeters on the back of the patient, and then the vertebrae are cut off and refixed with a bone grinding tool. [0004] However, in the prior art, the bone grinding tools al...
