Abstract: A treatment tool includes a housing, a sheath rotatable around a predetermined axis of rotation with respect to the housing. An end effector is disposed on a distal-end portion of the sheath and rotatable in unison with the sheath around the axis of rotation. A locking member for restraining rotation of the sheath with respect to the housing by engaging the sheath. A manipulating member is mounted on the housing and moves with respect to the housing for causing the locking member and the sheath to switch between engaging and disengaging positions.

Abstract: The disclosed technology is directed to a treatment instrument comprises an end effector having a pair of clamping members configured to pivot with respect to one another. A sheath is attached to the end effector along a longitudinal axis so that the end effector can be bent or curved. A drive shaft is connected to the end effector so as to guide the end effector to open or close the pair of clamping members relative to one another when moved in a longitudinal direction relative to the sheath. An elongated member is connected to the end effector and is configured to make the end effector bend or curve with respect to the sheath when moved in the longitudinal direction relative to the sheath. First and second members are configured to produce first and second forces sufficient to open or close the pair of clamping members.

Abstract: The disclosed technology is directed to a surgical instrument comprises a sheath having respective opposed proximal and distal ends. A pair of grasps is disposed on the distal-end portion of the sheath gripping a treatment target therebetween. A drive shaft is coupled to at least one of the pair of grasps to open or to close the pair of grasps by being moved along the longitudinal axis with respect to the sheath. Electric elements are used to apply treatment energy to the treatment target. A first operating device supplies the electric energy to the electric elements in a first supply state. A first member produces a force to open or close the pair of grasps and applies the force to the drive shaft. A second member is disposed in line with the first member and applies a force to the drive shaft in response to the operation input.

Abstract: A treatment instrument includes a rotating body and a housing. The rotating body includes a connecting portion including: a supported portion having a cylindrical outer peripheral surface, and an engaged portion that is adjacent to the supported surface. The housing includes a supporting portion that is configured to support the supported portion of the rotating body, the supporting portion being rotatable around a predetermined rotation axis; and an engaging portion that is configured to generate a frictional force larger than a frictional force between the supporting portion and the supported portion by coming into contact with the engaged portion.

Abstract: A control device for use with a treatment tool that includes a heating element to apply heat to a treatment target. The control device comprises a processor configured to set a target temperature for the heating element and to control the heating element so that temperature of the heating element follows the target temperature. The processor is configured to switch the control of the heating element from a first phase to a second phase. A first followability of the temperature of the heating element in the first phase is higher than a second followability of the temperature in the second phase. The processor is configured to terminate the controlling of following the temperature of the heating element to the target temperature when a parameter is beyond a predetermined range wherein the parameter being defined as a fluctuation between the temperature of the heating element and the target temperature.
