Another object of the present invention is to provide an endoscope medical electric burning appliance which is compact in structure, has less assembly man-hours, and is easy to assemble automatically.

To achieve the above object, the present invention is an endoscope medical electric burning appliance for use with an electric burner. The electric burning appliance comprises an operating handle and a rotary positioning device. The operating handle is provided with a cylindrical portion, a fastening portion and at least one positioning convex portion. The fastening portion and the positioning convex portion are disposed on the cylindrical portion, wherein the cylindrical portion is further provided with a first inner hole. The rotary positioning device is sleeved on the cylindrical portion. The rotary positioning device further includes a rotatable portion, a second inner hole, at least one engaging portion, and a plurality of fixing units. The rotatable portion rotatably connects the cylindrical portion. The engaging portion is disposed on the sidewall of the second inner hole and is engaged with the fastening portion. The fixing unit is respectively recessed into the sidewall of the second inner hole, wherein the rotatable portion is correspondingly disposed with the positioning convex portion, and the rotatable portion is rotated by the rotary positioning device to position the positioning convex portion on any corresponding fixing unit. The electric burning rods are respectively disposed on the second inner hole and the first inner hole, and are operably controlled by the operating handle.

The invention also has the following effects: when the operator's index finger rotates the rotation positioning device, the positioning convex portion of the sleeve portion generates a slight sound with the fixing unit, so that the operator has a better operational hand feeling.
