Abstract: An ultrasonic surgical system includes an ultrasonic transducer, a probe, and at least one circuit. The ultrasonic transducer is designed to ultrasonically vibrate. The probe is coupled to the ultrasonic transducer and is designed to treat a living tissue by the ultrasonic vibration. The circuit performs functions including detecting a pressing force of the probe against the living tissue, calculating a value of a product of the pressing force, an amplitude of the ultrasonic vibration, and a resonance frequency of the probe, comparing the calculated value with a predetermined product value, and generating a predetermined signal based on a result of the comparison.

Abstract: An ultrasound probe includes: a probe main body section to which ultrasonic vibration generated by an ultrasound transducer is transmitted; a controller that is connected to the ultrasound transducer and controls generation of the ultrasonic vibration; and a treatment section that is provided on a distal side of the probe main body section and forms a hole in a bone, which is a treatment target, with the ultrasonic vibration. The treatment section has a distal end and a proximal end and includes a columnar portion, a cutting portion that cuts the bone by crushing the bone with the ultrasound vibration and forms the hole, and a discharge portion that discharges cutting debris of the bone cut by the cutting portion toward the proximal end from the cutting portion, the discharge portion including a recessed portion formed in a groove shape inclined with respect to the longitudinal axis.

Abstract: An ultrasonic surgical includes an output unit, a transducer, a probe, an excision unit, and, a controller. The output unit generates a driving power. The transducer is connected to the output unit. The transducer converts the driving power into ultrasonic vibration. The probe transmits the ultrasonic vibration. The excision unit is provided in the probe. The excision unit is in contact with a predetermined portion of the cartilage. The excision unit heats the predetermined portion of the cartilage by ultrasonic vibration converted based on the driving power. The excision unit excises the cartilage by receiving pressure by an operator while being in contact with the cartilage. The controller controls the driving power output from the output unit so that the predetermined portion of the cartilage is heated to a temperature of 120° C. or higher within 2.2 seconds.

Abstract: In An energy treatment system, a judgment section judges whether a vicinity of a treated target, with which an end effector is in contact, is filled with a liquid, in a state that the end effector is in contact with the treated target and a driving current is being output from an output section. In the energy treatment system, a controller executes at least one of stopping an output of the driving current from the output section and issuing an alert to an effect that the liquid is not filled, based on a fact that the judgment section judged that the vicinity of the treated target is not filled with the liquid.
