Abstract

An ultrasonic surgical system includes a handpiece including an ultrasonic transducer and a first storage unit; a probe connected to the ultrasonic transducer; a calculation unit; and a control unit. The first storage unit stores a first parameter relating to control of the ultrasonic transducer. The probe transmits ultrasonic vibrations output from the ultrasonic transducer to a treatment target, and includes a second storage unit storing a second parameter relating to control of the ultrasonic transducer. The calculation unit calculates a control parameter for controlling the ultrasonic transducer, based on both the first parameter and the second parameter. The control unit controls the ultrasonic transducer based on the control parameter.

Claims

1. A probe connected to an ultrasonic transducer, transmitting ultrasonic vibrations output from the ultrasonic transducer to a treatment target, comprising:

a storage unit storing a parameter relating to control of the ultrasonic transducer, arranged in a portion of the probe, the portion of the probe corresponding to a node of a standing wave produced by the ultrasonic transducer;

an opening at least linking an end of the robe to which the ultrasonic transducer is connected and the portion of the probe corresponding to the node of the standing wave; and

a holding unit that holds the storage unit in the opening at the node of the standing wave, wherein

the holding unit includes a buffer material that is arranged in the opening to reduce stress to the storage unit caused by the ultrasonic vibrations.

2. The probe according to claim 1, wherein the holding unit holds the storage unit so that the storage unit can be replaced.

3. The probe according to claim 2, wherein

the holding unit is a supporting rod holding the storage unit at a tip of the rod so that the storage unit can be replaced, and when the supporting rod inserted in the opening is fastened with screws to the probe, the storage unit is arranged in the probe without contact with the probe.

4. The probe according to claim 1, wherein the storage unit is disposed near a center of a cross-section of the probe.
