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: An energy surgical instrument includes first and second grasping pieces for grasping a blood vessel. At least one of the grasping pieces is designed to apply treatment energy to a grasped blood vessel. The instrument also includes a processor designed to set a wall thickness of the blood vessel, and a grasping force adjuster designed to adjust a grasping force applied by the first and second grasping pieces. A first grasping force is applied when the wall thickness set by the processor is larger than a predetermined thickness, and a second grasping force, which is larger than the first grasping force, is applied when the wall thickness set by the processor is equal to or smaller than the predetermined thickness. A treatment method includes applying treatment energy to a blood vessel grasped by the first and second grasping pieces of the instrument to seal the blood vessel.

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: An energy surgical instrument includes a first grasping piece, a second grasping piece which is allowed to grasp a blood vessel, an energy application unit provided in at least one of the first grasping piece and the second grasping piece, which applies treatment energy to the blood vessel grasped, a setting unit which sets information regarding a wall thickness of the blood vessel, and a grasping force adjustment unit which adjusts a grasping force to a first grasping force when the wall thickness set by the setting unit is larger than a predetermined thickness and adjusting the grasping force to a second grasping force, which is smaller than the first grasping force, when the wall thickness set by the setting unit is equal to or smaller than the predetermined thickness.
