Abstract
The invention provides a cautery apparatus, which includes a cautery probe provided at the tip of a sheath that can be inserted into, for example, a treatment-tool channel of an endoscope, and also includes a liquid-supply pump to be connected to the sheath for supplying a liquid through nozzles formed in the cautery probe. The cautery apparatus comprises a pump driving motor provided in its main body, a pump unit containing the liquid-supply pump, an attaching device for detachably attaching the liquid-supply pump unit to the main body, and a coupling mechanism. The coupling mechanism couples the driving shaft of the liquid-supply pump to the driving shaft of the pump driving device to attach the liquid-supply pump unit to the main body, and separates the driving and driving shafts from each other to detach the liquid-supply pump unit from the main body.
