Abstract: A treatment system can include a treatment tool including an ultrasound transducer and an end effector. The system can also include an ultrasound power source configured to output a drive signal to the ultrasound transducer, and a processor configured to detect an abnormality in the end effector, and whether end effector is immersed in a liquid. The system can continue an output of the drive signal from the ultrasound power source to the ultrasound transducer when the abnormality is detected and the end effector is immersed in the liquid.

Abstract: A generator that includes a drive circuit connected to a surgical instrument including a vibration system having a probe and an ultrasonic transducer, which supplies power to the ultrasonic transducer. The control circuit detects a first trigger causing the control circuit to perform a resonance-point search on the vibration system. Upon detecting the first trigger, the control circuit determines a resonance point of a frequency of vibration of the probe by performing the resonance-point search, and upon determining the resonance point, causes the drive circuit to execute a standby operation. The control circuit then detects a second trigger causing the surgical instrument to treat the living tissue, and upon detecting the second trigger, causes the drive circuit to execute an actual output operation by increasing the supply of power to the surgical instrument such that the surgical instrument treats the living tissue.

Abstract: A method for controlling an energy treatment system includes performing treatment on a subject by a probe of an energy treatment instrument which outputs ultrasonic energy and high frequency energy in combination; setting an output reduction control period, based on information related to an amount of mist generated by the probe; and reducing the output of the high frequency energy during the output reduction control period when a precursor of occurrence of spark or occurrence of spark is detected.

Abstract: A treatment instrument includes: a sheath; and an end effector that is provided at a distal end of the sheath. The end effector is capable of gripping a living tissue and applying high frequency energy to the living tissue. The end effector includes a treatment surface, and a pair of electrodes that can grip the living tissue and apply the high frequency energy to the living tissue. The treatment surface includes a distal end area that is provided on a distal end side of the treatment surface, and another area that is provided on a proximal end side of the treatment surface. The distal end area applies, to the living tissue, high frequency energy that is higher than high frequency energy applied by the other area. One of the pair of electrodes includes a distal end portion and a proximal end portion.

Abstract: An energy treatment system and a output control method thereof according to embodiments of the present invention perform treatment by energy supply in which ultrasonic energy and high frequency energy are combined, stop or suppress discharge by reducing the output of high frequency energy within a set period when a state in which discharge is likely to occur during treatment is detected, and change the output of ultrasonic energy. In addition, in order for a user to continue treatment without feeling uncomfortable and to ensure incision performance, each output is controlled so that the set period is as short as possible or is supplemented, and also, the set period expires, and control is performed so as to reduce the possibility of discharge even at the time of returning.

Abstract: A power supply device for a high-frequency treatment instrument includes an output section, a characteristic detector, and a stop signal generator. The output section outputs power having a first frequency supplied to the high-frequency treatment instrument. The characteristic detector detects a characteristic signal generated before the power outputted from the output section becomes excessive, the characteristic signal having a second frequency higher than the first frequency and being included in a signal related to the power. The stop signal generator outputs a stop signal to stop or reduce an output of the power from the output section when the characteristic signal is detected.
