Patent ID: 7582055

Claim:
An endoscope system comprising: a treatment tool having a treatment-tool insertion unit to be inserted in a treatment-tool channel provided in an insertion unit of an endoscope and a function unit having a function for performing a certain treatment, which is introduced within a body cavity, provided at the tip side of the treatment-tool insertion unit; an electrically-driven operation device which electrically drives the function unit; an electrically-driven advance/retreat device which electrically drives the treatment-tool insertion unit; a control device, which is electrically connected to the electrically-driven advance/retreat device and the electrically-driven operation device, the control device including a control unit for outputting a control signal to the electrically-driven advance/retreat device and the electrically-driven operation device, and an operating program corresponding to a predetermined use of the treatment tool; an operation instructing device, which is electrically connected to the control device, the operating instructing device including a first operating instruction unit for outputting a first instruction signal for placing the electrically-driven operation device and the electrically-driven advance/retreat device into a manually-driven operating state, and a second operating instruction unit for outputting a second instruction signal for placing the electrically-driven operation device and the electrically-driven advance/retreat device into a programmed-control state by the operating program; wherein, when receiving a first instruction signal output from the operation instructing device, the control unit of the control device outputs the control signal corresponding to the first instruction signal to at least one of the electrically-driven advance/retreat device and the electrically-driven operation device, and when receiving a second instruction signal output from the operation instructing device, the control unit of the control device executes the operating program, and outputs the control signal in accordance with an instruction of the operating program to at least one of the electrically-driven advance/retreat device, and the electrically-driven operation device.
