Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 , figure 2 and image 3 As shown, the minimally invasive surgical instrument for treating spinal canal stenosis of the present invention includes a sleeve 2 and an ultrasonic osteotome 1 with the function of grinding bone. There is an axial channel 23 inside the sleeve 2 that can accommodate the ultrasonic osteotome 1 to pass through.

[0021] The front end of sleeve tube 2 has a long main body 21, so that it can avoid the bone tissue from the side of the human body and extend into the body to reach the bone grinding site of vertebral foramen or intervertebral foramen through minimally invasive surgery. The long body 21 has a hollow axial passage 23 therein. The rear end of the long body 21 is the insertion port 22 of the ultrasonic osteotome 1 . One or more inlets 24 connected with the axial channel 23 in the long main body 21 are provide...

Abstract

The invention discloses a minimally invasive surgical instrument for treating spinal canal stenosis. The instrument comprises a casing pipe and a piezosurgery. The front end of the casing pipe is provided with a long main body, and the rear end is the insertion port of the piezosurgery. The side surface of the rear end of the long main body is provided with access ports, used to access a wash pipe, a water absorption pipe, an endoscope conduit, and a lamp line pipe. The casing pipe is placed into a position of spinal aperture or an intervertebral foramen through a minimally invasive method. The piezosurgery is guided by a channel in the casing pipe to perform bone gridding or bone cutting. Since the space limitation of the casing pipe, damages on nerves by mistake when the piezosurgery is operated can be prevented. The wash pipe, the water absorption pipe, the endoscope conduit, and the lamp line pipe are guided by the casing pipe, preventing wound caused by passing into a body. When the wash pipe performs washing, the piezosurgery is cooled down. The minimally invasive surgical instrument changes an open method for treating spinal canal stenosis by a conventional instrument, and a minimally invasive surgical method is used to treat spinal canal stenosis, so as to satisfy requirements of surgical operation on accuracy and security.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument for treating spinal canal stenosis, which belongs to the technical field of medical instruments. Background technique [0002] The current surgical method for the treatment of spinal stenosis usually adopts an open surgical method to cut off the lamina with spinous processes, enlarge the space of the vertebral foramen, relieve the compression of the nerves in the spinal canal, and achieve the purpose of decompressing the nerves. However, this method will cause instability of the vertebral body due to the resection of the lamina, and it is usually necessary to add an additional internal fixation structure through surgery to increase the stability of the vertebral body. Therefore, the operation is complicated and the trauma is large. Great damage to human body. Contents of the invention [0003] Objective: In order to overcome the deficiencies in the prior art, the present invention pro...
