1. A ultrasonic operating apparatus comprising:

  • an ultrasonic transducer which generates ultrasonic vibrations;

    a probe portion which has a distal end and a proximal end, the proximal end being coupled to the ultrasonic transducer, ultrasonic waves output from the ultrasonic transducer being transmitted to the probe portion;

    a sheath portion which is formed by a cylindrical member having a distal end and a proximal end and into which the probe portion is removably inserted, the sheath portion having a jaw swingably supported on the distal end thereof to be opposite to the probe portion;

    a handle portion which is detachably coupled to the proximal end of the sheath portion and which opens/closes the jaw with respect to the probe portion, the handle portion having a transducer connecting portion to which the ultrasonic transducer is detachably connected; and

    a high-frequency electric path which is provided in a combination of the sheath portion and the handle portion and which transmits a high-frequency current,the high-frequency electric path having;

    a sheath portion side electric path disposed on the side of the sheath portion;

    a handle portion side electric path disposed on the side of the handle portion; and

    an electric connection portion which performs the operation of connecting the sheath portion side electric path and the handle portion side electric path along with the operation of connecting the sheath portion and the handle portion,the electric connection portion having;

    an outer peripheral flange portion which is disposed at the proximal end of the sheath portion and which is formed on the outer periphery of the sheath portion and which is connected to the sheath portion side electric path; and

    an engaging portion which is disposed inside the handle portion and which removably engages with the outer peripheral flange portion,the engaging portion being equipped with;

    an insertion hole forming portion into which the outer peripheral flange portion is inserted when the sheath portion is coupled to the handle portion; and

    an urging portion disposed in the insertion hole forming portion, the urging portion being switched between a non-pressure-contact position where the urging portion is held out of pressure-contact with the outer peripheral flange portion and a pressure-contact position where the urging portion is brought into pressure-contact with the outer peripheral flange portion, the urging portion permitting conduction between the sheath portion side electric path and the handle portion side electric path at the pressure-contact position.
