[0002] Arthroscopic surgery is a minimally invasive surgery on joints. An endoscope is inserted into the joint through a small incision, and the orthopedic surgeon examines and treats the joint based on the video images sent back by the endoscope. Current arthroscopic surgery mainly uses an outside-in approach, inserting a syringe needle, pulling out the needle, and using a sharp knife to cut the skin according to the position of the needle in the skin to establish an access route. Then, an expansion channel is established in the skin. After the channel is stabilized, an endoscope is finally inserted into the channel for subsequent examination and treatment. However, the existing method has the problem of the channel closing when the endoscope is inserted after the channel is established with the sharp knife. This will prevent the doctor from performing correct positioning and will also make subsequent operations inconvenient. Summary of the Invention
