It is connected. (21) is an operation switch that controls the operation of the working medium supply control section (14) by operating the hood, for example, and outputs the working medium from the working medium supply circuit set to supply the working medium.

In use, for example, in FIG. 1, the hand-held members (3) that are compatible with the joint members (2) are connected, and the respective compatible signals are output from each treatment instrument B to the identification command circuit (8). First, hold the first treatment instrument Ba with the holding member (5) a.
