    Abstract: A control device includes a processor configured to: execute a sealing control mode in which electrical power to seal a living tissue by heating the living tissue at a first temperature is supplied, and an incision control mode in which electrical power to incise the living tissue by heating the living tissue at a second temperature higher than the first temperature is supplied; calculate elapsed time, as an index value, since it has reached the second temperature by executing the incision control mode; compare the index value and a threshold; determine a residual heat level of an end effector based on a result of comparison between the index value and the threshold; and perform, based on a determination result of the residual heat level, at least one of: notification of information indicating a warning from a notifying unit; and adjustment of electrical power supplied to the end effector.

    Abstract: In a treatment system, an energy treatment instrument includes a pair of grasping pieces. An energy output source outputs electric energy to the energy treatment instrument, thereby applying treatment energy to a blood vessel grasped between the grasping pieces. A measurement section measures a blood pressure at a site related to the grasped blood vessel. A processor controls output of the electric energy from the energy output source based on a measurement result obtained by the measurement section, and thereby switches an actuation state of the energy treatment instrument between a first mode for coagulating the blood vessel and a second mode for coagulating the blood vessel target that is different from the first mode.

    Abstract: In a treatment system, a treatment instrument includes a pair of grasping pieces each of which includes an electrode. A control device outputs electric energy to the electrodes and thereby supplies a high-frequency current to a treatment target. The control device switches between a first mode and a second mode that is different from the first mode in control scheme regarding output of the electric energy to the electrodes, based on a load that acts on one of the grasping pieces.

    Abstract: In a treatment system, an energy treatment instrument includes a pair of grasping pieces closing with respect to each other. An energy output source outputs electric energy to the energy treatment instrument, thereby applying treatment energy to a treatment target grasped between the grasping pieces. A processor creates an optical flow of the treatment target observed by an observation element, and switches an actuation state of the energy treatment instrument between a first mode for treating the treatment target and a second mode for treating the treatment target that is different from the first mode, based on the optical flow.
