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.

Abstract: A control device having: one or more processors configured to: receive a first signal indicating one of a plurality of inputs of a first type received by a first input device; receive a second signal indicating one of a plurality of inputs of a second type received by a second input device; select a selected mode from one or more modes of a respective one or more treatment devices based on a combination of the first signal and the second signal; and output a control signal for controlling the one or more treatment devices in accordance with the selected mode.

Abstract: An ultrasonic treatment system includes a probe which transmits ultrasonic vibration. In the system, a first energy generator generates treatment energy suitable for treating a living tissue in accordance with an instruction from a first instruction part. The probe is made ultrasonically vibrate with the first amplitude. A second energy generator generates destruction energy suitable for destroying the probe in accordance with an instruction from a second instruction part. The probe is made ultrasonically vibrate with the second amplitude.

Abstract: An ultrasonic surgical instrument includes an ultrasonic vibrator, a vibration transmission section, a grip member, a pad member provided at a position of the grip member which faces the treatment section, and a planar facing surface disposed on the pad member. A distal end portion of the treatment section faces the pad member, and is curved from a proximal end portion side of the treatment section toward the distal end portion side of the treatment section in a direction away from the facing surface. The pad member includes a protruding portion which is disposed on the facing surface, protrudes from the facing surface toward the distal end portion of the treatment section, and abuts on the distal end portion of the treatment section while the grip member is closed.

Abstract: An actuator system including a drive section that performs driving by injection/suction of a liquid, a tube, a syringe pump that injects/suctions the liquid into/from the drive section via the tube, a pressure sensor that measures an inner pressure, a storage section that preliminarily stores a volume change ?V of the tube caused by the inner pressure, and a control section that controls the syringe pump based on the volume change ?V, inner pressure P, and volume V0 of the liquid injected/suctioned into/from the drive section.

Abstract: A belt assembly is arranged on a back side of a backrest of a baby carriage, so that the angle of inclination of the backrest may be changed by adjusting of the length of the belt assembly. The belt assembly includes a first belt, a second belt, and a buckle which is attached to an end of the first belt and which has the second belt passing therethrough. The second belt has on its first major surface a plurality of engaging cavities. The buckle holds an operating member, which is cross-directionally or laterally movable across the second belt, and which is urged by a spring to move downwardly. The operating member is provided with engaging projections, which can selectively engage the engaging cavities. The length of the belt assembly is fixed when the engaging projections engage the engaging cavities, while the length of the belt assembly is rendered changeable when the former disengage from the latter.
