Description

Technical Field

[0001] The utility model relates to the technical field of intervertebral foraminal endoscopes, in particular to a cleaning device for intervertebral foraminal endoscopes. Background Art

[0002] The perforaminal endoscope is similar to a spinal endoscope. It is a tube equipped with a light. It enters the intervertebral foramen from the side or back of the patient's body and performs surgery in the safe working triangle. The surgery is performed outside the annulus fibrosus of the intervertebral disc. Under direct endoscope vision, the protruding nucleus pulposus, nerve roots, dura mater sac and hyperplastic bone tissue can be clearly seen. Then various forceps are used to remove the protruding tissue, remove bone under the microscope, and radiofrequency electrodes are used to repair the damaged annulus fibrosus. The surgery is minimally invasive, with a skin incision of only 7mm, less than 20ml of bleeding, and only one stitch is needed after the surgery. It is a minimally invasive treatment for intervertebral disc herniation with the least trauma to the patient and the best effect among similar surgeries.

[0003] The perforaminal lumbar endoscope itself is a medical device inserted into the human body, so the requirements for its cleaning and disinfection are very important; however, the exterior of the existing perforaminal lumbar endoscope is usually cleaned in batches, which leads to the problem of incomplete cleaning of the perforaminal lumbar endoscope and easy breeding of bacteria. The working channel of the perforaminal lumbar endoscope is usually cleaned manually, which has problems such as inadequate cleaning or low cleaning efficiency, which seriously affects the next use.
