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: A surgical treatment instrument includes an elongated member an end effector that is bendable with respect to the elongated member, a bending operator operable to bend the end effector, a rotor rotatable about a rotation axis in response to operation of the bending operator, and a transmitter that transmits a driving force to bend the end effector. The bending operator, the rotor, and the transmitter are rotatable about the longitudinal axis together with the elongated member and the end effector.

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: A treatment instrument includes a sheath having a longitudinal axis, an end effector provided on one end of the sheath, a housing to which the other end of the sheath is connected, and an operation dial provided to be rotatable relative to the housing around a first rotational axis. The operation dial includes a first outer peripheral surface provided around the first rotational axis, and a second outer peripheral surface spaced apart from the first outer peripheral surface in a direction along the first rotational axis and provided around the first rotational axis.

Abstract: A surgical treatment instrument includes a holdable housing, a shaft, an end effector configured to perform a bending movement with respect to the shaft, a rotor configured to rotate about a rotation axis in response to an operation input performed through an operation member, and a transmission member configured to transmit a driving force for causing the end effector to perform the bending movement to the end effector. The operation member and the transmission member are configured to rotate together with the shaft and the end effector in response to the operation input, and the rotor is configured to not rotate together with the shaft and the end effector when the operation input is performed.

Abstract: In a treatment instrument, one of a pair of jaws is supported by a supporter while being pivot able around the supporter with respect to the supporter. A drive member moves along a longitudinal axis so that the pair of the jaws are closed with respect to each other, thereby applying an axial force onto an elongated member from the drive member by way of the one of the jaws and the supporter in a direction along the longitudinal axis. A contact surface of the elongated member abuts on a housing when the elongated member moves with respect to the housing under the axial force, thereby suppressing rotation of the elongated member around the longitudinal axis with respect to the housing.

Abstract: A treatment tool includes a rotary member that is rotatable in unison with an elongated member such as a sheath or shaft and an end effector around a predetermined axis of rotation with respect to a housing. The rotary member has a ridge projecting toward an outer circumferential side and extending from a proximal-end side toward a distal-end side. The treatment tool includes a cavity that is concave toward an inner circumferential side. The cavity is contiguous to the distal-end side of the ridge on the rotary member or is disposed on the distal-end side from the ridge on the housing.
