Abstract: A grasping treatment device includes a probe including a first electrode portion in its distal portion, and a jaw configured to open or close relative to the first electrode portion and including a second electrode portion. The grasping treatment device includes a grasping force converting unit converting a grasping force so that a second grasping force between the distal portion of the probe and the jaw in a second treatment mode in which high-frequency current alone is transmitted to the first electrode portion and the second electrode portion is greater than a first grasping force between the distal portion of the probe and the jaw in a first treatment mode in which at least an ultrasonic vibration is transmitted to the distal portion of the probe.

Abstract: A jaw of the grasping treatment device includes an abutting portion being abutable on a probe treatment portion when the jaw is closed relative to the probe treatment portion, and a separated portion being disposed with a clearance between the separated portion and the probe treatment portion when the abutting portion is in abutment with the probe treatment portion. The jaw includes a distal-side wall portion provided to a distal direction side of the separated portion and protruding toward the probe treatment portion as compared with the separated portion, and a proximal-side wall portion provided to a proximal direction side of the separated portion and which protruding toward the probe treatment portion as compared with the separated portion.

Abstract: A treatment instrument includes: a first treatment section which includes a first body including a first contact surface and a second body including a second contact surface; a movement mechanism which is configured to switch between a closed position in which the first contact surface and the second contact surface are close to each other, and an opened position in which the first contact surface and the second contact surface are distant from each other; and a second treatment section which is disposed on a distal side along the longitudinal axis with respect to the first treatment section when the first contact surface and the second contact surface are located in the closed position, and which is configured to apply energy to the living tissue to incise or separate the living tissue.

Abstract: A treatment device includes a first grip member having an elongated shape, and a second grip member which is displaced with respect to the first grip member to grip the biological tissue between the first grip member and the second grip member. The second grip member includes a grip section that comes into contact with a biological tissue as a gripping target. I/A2 of the grip section is maximum at the proximal end, and/or Z/A3/2 of the grip section is maximum at the proximal end, where I is a second moment of area, Z is a section modulus, and A is a cross-sectional area calculated based on an axis perpendicular to a straight line passing through a center of gravity of the first grip member and a center of gravity of the second grip member in a cross section perpendicular to a longitudinal axis of the grip section.

Abstract: A grasping treatment device includes a first electrode portion provided at least one of in a part between a jaw and a probe electric conducting portion in opening-and-closing directions of the jaw and in the probe electric conducting portion, and a second electrode portion provided at least one of in a part between the jaw and the first electrode portion in the opening-and-closing directions of the jaw and in a jaw electric conducting portion. The grasping treatment device includes an inter-electrode distance changing unit changing an inter-electrode distance so that a second distance between the electrode portions in a second treatment mode, in which the high-frequency current alone is transmitted to the first electrode portion and second electrode portion, is smaller than a first distance between the electrode portions in a first treatment mode, in which at least an ultrasonic vibration is transmitted to a probe electric conducting portion.
