    Abstract: A treatment system includes a treatment tool and an energy source apparatus. The treatment tool includes a heater and bipolar electrodes to grip a treatment target. The energy source apparatus supplies electrical energy to the treatment tool. A processor controls the output to the bipolar electrodes and the heater. The processor causes a high-frequency electric power to be output to the bipolar electrodes and detects a parameter that varies depending on tissue volume of the treatment target. The processor sets a target value related to an output control process for controlling the output to the heater. The processor controls the output to the heater so as to modify the treatment target with the heat of the heater. The processor increases the output and temperature to the heater until at least a predetermined point of time after starting the output control process for controlling the output to the heater.

    Abstract: A treatment system includes a treatment tool and an energy source apparatus used to supply electrical energy to the treatment tool. The treatment tool includes a heater and bipolar electrodes to grip a treatment target. The energy source apparatus includes a processor to control the output to the bipolar electrodes and the heater, respectively. The processor directs the output to the bipolar electrodes and detects an initial value of the impedance of the treatment target. The processor determines whether or not the impedance has reached a minimum value and then retrieves a parameter that is detected before the minimum value of the impedance is detected. The processor performs a first process and/or a second process based on the acquired parameter after the minimum value is detected. The first process determines whether or not the output to the heater is required. The second process sets a target value.

    CPC classification number: A61B18/1445 ,  A61B2018/00607

    Abstract: A thermocoagulation/cutting device 11 includes an exothermic part 13 made of a meta; a first current supply portion 41 projecting integrally from the exothermic part 13; a second current supply portion 42 projecting integrally from the exothermic part 13; and a third current supply portion 43 projecting integrally from the exothermic part 13. The thermocoagulation/cutting device 11 includes a controller 16. The controller 16 is capable of causing an electric current to flow between the first current supply portion 41 and second current supply portion 42, between the first current supply portion 41 and third current supply portion 43, or between the second current supply portion 42 and third current supply portion 43.

    Abstract: An energy treatment instrument includes a first grasping piece, and a second grasping piece opening and closing relative to the first grasping piece and grasping a treated target between the first grasping piece and the second grasping piece. An actuation state of the energy treatment instrument is switched between a first mode in which the treated target is coagulated when a forceps does not exist in a predetermined range from a position where the treated target is grasped, and a second mode in which the treated target is coagulated when the forceps exists in the predetermined range.

    Abstract: A medical device includes: an end effector configured to apply treatment energy for treating a living tissue according to supplied power; a drive source configured to supply the power to the end effector; and a processor configured to classify, in a first time period after a supply of the power to the end effector is started, the living tissue into any one of a plurality of tissue types based on a first parameter detected in the first time period, control an operation of the drive source after the first time period based on the classified tissue type, reclassify the classified living tissue into any one of the plurality of tissue types based on a second parameter detected after the first time period, and control an operation of the drive source based on the tissue type into which the classified living tissue is reclassified.
