Description

Intervertebral foramen mirror operation device

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to foraminiferous mirror operation device.

Background

The transforaminal endoscope is similar to a spinal endoscope and is a tube provided with a light, and the tube enters an intervertebral foramen from the side or the lateral back of the body of a patient (can be flat and can be inclined), and the operation is carried out in a safe working triangular area. The operation is performed outside the intervertebral disc fibrous ring, the protruded nucleus pulposus, the nerve root, the dural sac and the proliferated bone tissues can be clearly seen under the direct vision of the endoscope, and the minimally invasive treatment method for the intervertebral disc protrusion has the advantages of minimal trauma to patients and best effect in similar operations. The operation method is a spine minimally invasive surgery system which is formed by a specially designed intervertebral foramen mirror, a corresponding spine minimally invasive surgery instrument, an imaging and image processing system and the like. While the herniated or prolapsed nucleus pulposus is completely removed, the hyperosteogeny is removed, spinal stenosis is treated, the damaged annulus fibrosus can be repaired by using radio frequency technology, and the like. The successful establishment of the working channel of the foraminoscope is the key to the success of the operation, and the intervertebral foramen formation is the most key step for establishing the channel. The so-called foramen vertebroplasty is to remove a portion of the articular process and remove peripheral obstructions, and to enlarge the foramen space to allow the working channel to enter and reach the location of the protruding nucleus pulposus. The conventional arthroplasty procedure has drawbacks: the bone and the barrier cannot be abraded and removed under the direct vision of an endoscope, the positions of the bone and the barrier abraded by the abrasive drill are repeatedly confirmed by means of blind operation or X-ray fluoroscopy, the probability of damaging the nerve and spinal cord is indirectly increased, X-ray fluoroscopy is repeated, and the exposure of X-ray of doctors and patients is excessive and harmful to the body.
