Description

Technical Field

[0001] The invention relates to the technical field of endoscopes, and in particular to a large-channel percutaneous spinal endoscope suitable for an endoscopic fusion device. Background Art

[0002] An endoscope is a tube equipped with a light. It can enter the stomach through the mouth or enter the body through other natural orifices. The fusion device is mainly used to treat diseases such as lumbar spondylolisthesis. The fusion device enters the patient's body through a tube and is precisely installed in the affected area. At this stage, the installation of fusion devices is mostly performed using minimally invasive surgery in conjunction with a medical endoscope.

[0003] At present, the diameter of the endoscope insertion tube is too small to pass through the fusion device, and the traditional endoscope insertion tube is connected with connecting devices such as wires and optical fibers, which is not convenient for the fusion device to pass through. In addition, the fusion device installation device is used separately from the existing endoscope, and requires the cooperation of multiple doctors. The operation process is cumbersome and also wastes medical resources. The traditional combined endoscope needs to rotate the endoscope camera synchronously when rotating and adjusting the fusion device. After the fusion device is positioned, the camera angle must be readjusted before installation, which is troublesome to use. At the same time, there is a gap between the traditional combined endoscope and the fusion device installation device. During the rotation process, the fusion device installation device will collide with the endoscope, resulting in an unstable angle adjustment. In view of the above problems, a large-channel percutaneous spinal endoscope suitable for endoscopic fusion devices is proposed. Summary of the invention
