  • Patent number: 10687841
    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.
