Endoscopy system

An endoscopy system comprising:

• an operating device that an operation section of an accessory is attachable to, the operating device operating the operation section in a motor-driven manner, the accessory having an accessory insertion section to be introduced into a body cavity through an insertion section of an endoscope;
• a forward/backward moving device arranged in an operation section of the endoscope, the forward/backward moving device moving the accessory insertion section forward or backward in a motor-driven manner;
• a control device electrically connected to the forward/backward moving device and the operating device, the control device including a control unit for outputting control signals to the forward/backward moving device and the operating device and a memory unit for storing one or more treatment operation programs corresponding to accessories to be mounted on the operating device;
• and
• an operation instructing device electrically connected to the control device, the operation instructing device including a manual operation unit, a first operation instructing unit for outputting a first instruction signal corresponding to the operation of the manual operation unit, and a second operation instructing unit for outputting a second instruction signal, wherein
• when receiving the first instruction signal, the control device outputs a control signal corresponding to the first instruction signal to at least one of the forward/backward moving device and the operating device, and when receiving the second instruction signal, the control device executes the treatment operation program stored in the memory unit and then outputs a control signal, based on the operation according to the treatment operation program, to at least one of the forward/backward moving device and the operating device.
