Abstract:
1. A grasping treatment device comprising: a probe body which is configured to transmit an ultrasonic vibration from a proximal direction toward a distal direction, and which is configured to transmit a high-frequency current; a sheath body through which the probe body is inserted, and which is configured to transmit the high-frequency current, the sheath body being electrically insulated from the probe body; a jaw attached to a distal portion of the sheath body to be openable and closable relative to a distal portion of the probe body; a probe electric conducting portion which is provided to the distal portion of the probe body, and to which the ultrasonic vibration is transmitted through the probe body, the probe electric conducting portion having a first electric potential when the high-frequency current is transmitted thereto through the probe body; a jaw electric conducting portion provided in the jaw and facing the probe electric conducting portion, the jaw electric conducting portion having a second electric potential different in intensity from the first electric potential when the high-frequency current is transmitted thereto through the sheath body; a movement electric conducting portion which is movable with respect to the probe body and the sheath body, and to which the high-frequency current is transmitted through the probe body or the sheath body, the movement electric conducting portion having the first electric potential or the second electric potential when the high-frequency current is transmitted; and a movement operation input portion configured to input an operation of moving the movement electric conducting portion between a first movement position in which the movement electric conducting portion is located to a proximal direction side with respect to the jaw and a second movement position in which the movement electric conducting portion located between the probe electric conducting portion and the jaw electric conducting portion in opening-and-closing directions of the jaw.
