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.

Abstract: A treatment tool includes a first grasper and a second grasper. The first grasper includes a treatment portion that includes a treatment surface and an opposing surface, and a holder portion that is mounted on the opposing surface. The holder portion is formed of an elastically deformable material, and includes a first region having a first contact surface, a second region having a second contact surface, and a connection region that is arranged between the first contact surface and the second contact surface and that includes a concave portion. The holder portion is mounted on the opposing surface in an elastically deformed state such that the first contact surface and the second contact surface are in contact with the opposing surface and such that a depth of the concave portion is smaller than a depth of the concave portion is a non-elastically deformed state.

Abstract: A medical treatment device includes: a pair of holding members configured to grasp a target part to be connected in a body tissue; an energy application portion provided on at least one holding member of the pair of holding members, the energy application portion being configured to contact the target part when the target part is grasped by the pair of holding members to apply energy to the target part; and a processor including hardware. The processor is configured to cause the energy application portion to: apply high-frequency energy to the target part for a first period; apply ultrasound energy to the target part for a second period subsequent to the first period; and apply heat energy to the target part for a third period subsequent to the second period.
