Neuroendoscopic operation working channel and method for manufacturing the same

The invention belongs to the field of medical devices and provides a neuroendoscopic operation working channel and a method for manufacturing the same. The working channel is of a winding drum structure through the curling of a rectangular material, the winding drum can reduce its diameter under the effect of external force and can increase its diameter under the effect of its tension. The neuroendoscopic operation working channel is simple to manufacture and low in cost, can effectively replace an expensive retractor, is better in effect and reduces the damage to organs.
