    Abstract: A treatment system includes a treatment tool and a generator. The treatment tool includes a first grasper configured to apply treatment energy to a living tissue, and a second grasper. The generator includes a power circuit, a detecting circuit configured to detect an index value indicating a treatment state of a test material, and a processor configured to, based on the index value, measure a treatment completion time. At least one of the treatment tool and the generator further includes a memory configured to store property data which indicates a property of the test material, and based on the measured treatment completion time, the intensity of the treatment energy applied to the test material, and the property data, the processor is configured to calculate a control parameter related to the intensity of the treatment energy when the living tissue is treated, and output the control parameter to the power circuit.

    IPC: A61B18/14

    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: In a treatment instrument, a shaft is rotatable around a predetermined rotation axis relative to the housing, and an end effector is bendably or curvably attached to the shaft. In the treatment instrument, an interlocking member is provided independently of the shaft, and a receiver is provided in such a manner that rotation of the receiver relative to the housing is restricted or that rotation of the receiver relative to the shaft is restricted. The interlocking member moves in conjunction with bending or curving movement of the end effector so that the receiver engages with the interlocking member, thereby preventing rotation of the shaft around the predetermined rotation axis.

    Abstract: A medical treatment implement including: a shaft extending along a longitudinal axis; a housing having distal and proximal portions, a proximal end of the shaft being attached to the distal portion of the housing to extend from the distal to the proximal portion, the elongated shaft being rotatable about the longitudinal axis relative to the housing; an effector attached to a distal end of the shaft, the effector articulating relative to the longitudinal axis; a drive mechanism having an output connected to the effector to articulate the effector relative to the shaft; and an input unit attached to the housing at a position closer to the proximal portion than the distal portion, wherein the input unit receives an operation input and directly inputs the drive mechanism in response to the input, wherein the input unit rotates about the longitudinal axis together with the shaft relative to the housing.
