1. A treatment system comprising:
a treatment tool configured to apply, to a living tissue, treatment energy generated according to electrical power supplied to the treatment tool, the treatment tool including:
a first grasper configured to apply the treatment energy to the living tissue, and
a second grasper configured to grasp the living tissue along with the first grasper; and
a generator including:
a power circuit configured to supply the electrical power to the treatment tool,
a detecting circuit configured to detect an index value indicating a treatment state of a test material which is grasped between the first grasper and the second grasper and to which the treatment energy is applied from the first grasper, and
a processor configured to, based on the detected index value, measure a treatment completion time spanning from a start of application of the treatment energy to the test material to a completion of a specific treatment in the test material, wherein:
at least one of the treatment tool and the generator further includes a first memory configured to store property data that indicates (i) a property of the test material and (ii) a relationship between an intensity of the treatment energy applied to the test material and the treatment completion time, and
based on the measured treatment completion time, the intensity of the treatment energy applied to the test material, and the stored 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 calculated control parameter to the power circuit to control the supply of the electrical power to the treatment tool.
