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 treatment device includes a treatment portion, a transmission portion and a moment shift portion. The treatment portion transmits ultrasonic vibration. The length of the treatment portion is shorter than ¼ of a wavelength of the ultrasonic vibration. The transmission portion has one end at a node position where the first generated node from the distal end of the treatment portion appears, and is located closer to a proximal side than the node position. The length of the transmission portion is ¼ of the wavelength. The moment shift portion is located between the treatment portion and the transmission portion. An average of I1/A12 is greater than an average of I2/A22, where I1 is the second moment of area and A1 is a sectional area in the treatment portion, and I2 is the second moment of area and A2 is a sectional area in the transmission portion.

Abstract: An ultrasonic treatment instrument for articulations has a bone abrasion mode in which vibration is performed at a first frequency and a first amplitude, and a cartilage dissolution mode in which vibration is performed at a second frequency which is higher than the first frequency, and a second amplitude which is less than the first amplitude, wherein a first vibration velocity, which is a product of the first frequency and the first amplitude, and a second vibration velocity, which is a product of the second frequency and the second amplitude, coincide or substantially coincide.

Abstract: A high-frequency electrosurgical treatment instrument for operations, includes a pair of forceps pieces, an insulating member, a transmission member, a manipulation rod member, a distal end cover member, a shaft member and a manipulation portion. The instrument, includes a flow channel portion formed between the manipulation rod member and the shaft member, the flow channel portion being disposed along a longitudinal direction of the manipulation rod member to allow liquid to flow; a groove portion that communicates with the flow channel portion to allow the liquid to flow from the flow channel portion; and an opening portion that communicates with the groove portion to supply the liquid near the proximal end portions of the pair of forceps pieces.
