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.

High-frequency electrosurgical treatment instrument for operations and high-frequency electrosurgical system for operations

A forceps system includes a forceps manipulator and a control unit. The forceps manipulator includes a forceps tip unit capable of bending with two degrees of freedom including a bending direction and a bending angle, a drive unit that generates a driving force for the forceps tip unit, an operation unit for instructing the bending direction and the bending angle, and a first detection unit that detects an angle in a rotation direction with respect to an axis of the drive transmitting unit. The control unit that controls the drive unit such that the forceps tip unit bends depending on a predetermined target bending direction and a predetermined target bending angle. The control unit sets a target bending direction on the basis of the bending direction instructed from the operation unit and the angle detected by the first detection unit.
