Abstract: An apparatus for supporting a medical instrument includes an arm, which has a support portion to support a medical instrument at one end, and an intermediate portion of which is supported by a base portion via a support column. The arm moves the support portion horizontally and vertically. The apparatus also includes a rotary connecting member, which is provided at a second end of the arm and moves to a position corresponding to a position to which the support portion has been moved. The apparatus further includes a counterweight, which is connected to the support column to be immovable in the horizontal directions and movable in the vertical directions, and generates vertically downward force. The rotary connecting member is connected to the counterweight so as to be movable in the horizontal directions relative to the counterweight and movable in the vertical directions together with the counterweight.

Abstract: A power driven bending endoscope with detachable insertion portion 2 is formed of an insertion body 3 having a flexible bending portion 3B, and a motor unit 4 having an electric motor 23 for driving to bend the bending portion 3B and a potentiometer 26 for detecting a bending state of the bending portion 3B, which are detachably coupled.
