Abstract: A treatment instrument includes a grasping piece that is openable and closable to a treatment portion, and includes an electrode member. An electrode inclination surface facing a side on which the treating portion is located is provided on an outer surface of the electrode member of the grasping piece, and the electrode inclination surface extends from an inner side to an outer side in a width direction so as to be inclined in a direction away from the treatment portion.

Abstract: An electrode with a conduit includes: a tubular portion internally provided with a first conduit; a distal end portion provided at the distal end of the tubular portion; a second conduit that is provided inside the distal end portion, the second conduit being configured to communicate with the first conduit; an opening configured to communicate with the first conduit and the second conduit; a first hemostatic surface that has a flat surface extending from the distal end of the tubular portion in an extending direction of the second conduit, and serves as an electrode configured to cause a high-frequency current to flow through a biological tissue; and a second hemostatic surface that is connected to a distal end side of the first hemostatic surface and is provided at an end portion protruding toward a distal end side from the opening.

Abstract: A treatment device includes a probe having a treatment portion to treat a biological tissue by using the ultrasonic vibration generated in an ultrasonic transducer; an action portion being able to be close to and away from the treatment portion and including a pressing portion that presses the biological tissue to the treatment portion; and a vibration damping portion disposed in a part of the pressing portion in a state of facing the treatment portion, moving following the treatment portion to which the ultrasonic vibration is transmitted when abutting on the treatment portion in a state where the ultrasonic vibration is transmitted to the treatment portion, and prevented from being grinded by the treatment portion to which the ultrasonic vibration is transmitted.
