Description

Reciprocating type resection device of intervertebral disc under adjustable type backbone scope

Technical Field

The utility model relates to the field of medical equipment, concretely relates to reciprocating type resection device of intervertebral disc under adjustable type backbone scope.

Background

The intervertebral disc is a nucleus pulposus which is positioned between two vertebral bodies of a vertebral column of a human body and is divided into a central part and elastic colloidal substances; the fiber ring at the periphery is formed by arranging a plurality of layers of fibrocartilage rings according to concentric circles; one side of the cartilage plate is tightly connected with the fibrous ring and nucleus pulposus tissues of the intervertebral disc, and the other side of the cartilage plate is connected with the vertebral body, so that the function of fixing and protecting the nucleus pulposus from the upper part and the lower part is achieved. The lumbar annulus fibrosus is thick in the front and thin in the back, and the nucleus pulposus is easy to be pulled out from the back and the outside, and protrudes into the vertebral canal or intervertebral foramen to press the spinal cord or spinal nerves, so that lumbago and lower limb radiating pain are caused, and the prolapse of intervertebral disc is formed. Lumbar intervertebral disc protrusion is the most common spinal surgical disease, and most patients can relieve symptoms through non-operative treatment methods such as traction, massage and the like and drug treatment in the early stage, but still a lot of patients need to be treated through operation finally.

With the popularization of the minimally invasive concept and the improvement of the minimally invasive technology, the percutaneous spinal endoscopy type is widely adopted at present for treating the lumbar intervertebral disc protrusion at home and abroad, and comprises endoscopic pure nucleus pulposus extirpation or endoscopic inferior intervertebral disc extirpation and intervertebral bone grafting fusion internal fixation. However, since the spinal endoscope operation channel is only 7mm in diameter and is often implanted at an angle to the intervertebral space in the operation area. Intervertebral discectomy apparatus is mostly "gun type" long handle operating device under the scope, nucleus pulposus pincers are main under the scope, it is limited to grab the ability, it is difficult to carry out high-efficient excision to tough nucleus pulposus and fibrous ring in geology, simultaneously, nucleus pulposus pincers excision intervertebral disc tissue is with "point" formula is grabbed and is amputated and is given first place to, the adnexed cartilage of centrum end plate and nucleus pulposus also hardly use current scope operating device to effectively amputate and realize the end plate and polish, and this will directly influence intervertebral discectomy efficiency and the exposure of implanting the bone face under the scope among the centrum fusion art formula, thereby it fuses the success rate to directly influence the bone between the centrum under the operation efficiency scope.
