[0002] Endoscopes are used to enter the human body and perform a series of operations such as inspection, biopsy, endoscopic treatment, etc., and are widely used in clinical practice. At present, when an endoscope is used during surgery, the position of the opening in the patient's skin cannot be highly consistent with the position of the lesion. When the catheter is inserted into the body through the hole in the skin, although the catheter can be bent and adjusted, it cannot be rotated. Therefore, when in use, the doctor needs to manually rotate the front end of the endoscope to drive the catheter to rotate, so as to find the location of the lesion. Such an adjustment operation is very inconvenient and can easily cause secondary damage to the position of the skin opening, thereby affecting the quality and effect of the operation. Therefore, the performance of existing endoscopes cannot meet the use requirements and needs to be improved. Summary of the invention
