Description

Technical Field

[0001] The utility model relates to the technical field related to endoscope tools, and in particular to a fixing device for an endoscope and an endoscope system. Background Art

[0002] Endoscopic spinal surgery is a minimally invasive surgical procedure primarily used to treat spinal diseases. Through a small incision in the skin, an endoscope several millimeters in diameter and related instruments are inserted. With the assistance of an imaging system, the internal spinal pathology can be directly observed and appropriate treatment procedures performed. For patients with lumbar disc herniation who have not responded to conservative treatment, endoscopic spinal surgery can directly remove the protruding nucleus pulposus, relieving nerve compression. For patients with lumbar spinal stenosis, it can remove bone hyperplasia, thickened ligamentum flavum, and other tissues that cause spinal stenosis, thereby expanding the spinal canal. For patients with cervical spondylotic radiculopathy, endoscopic cervical surgery can relieve nerve root compression.

[0003] During unilateral, dual-channel spinal endoscopic surgery, the surgeon must hold the scope with one hand to observe the surgical field while using the other to perform decompression. This leads to limitations such as poor stability and limited manipulation. These limitations require the surgeon to spend more time adjusting the position and angle of the instruments and finding the optimal surgical path. This not only increases the difficulty of the surgery but also prolongs the operation. This prolonged operation, in turn, increases the patient's anesthesia and infection risks, while also increasing surgical costs.

[0004] Currently, no effective solution has been proposed for the problems of poor operational stability and operational limitations in related technologies. Utility Model Content
