Ultrasonic surgical apparatus with treatment modes selectable
First Claim
1. An ultrasonic surgical apparatus comprising:
- a treatment device with an ultrasonic transducer driven to generate ultrasonic vibration in response to supply of current;
an operation device outputting a signal commanding the ultrasonic transducer to start driving in response to an operator'"'"'s operation;
a driver driving the ultrasonic transducer by supplying the current thereto; and
a controller controlling the driver to supply the current so that the current having a predetermined amount is supplied in response to the signal outputted from the operation device and then the current is reduced in amount as a time counted from starting the supply elapses.

Abstract
An ultrasonic surgical apparatus comprises a treatment device with an ultrasonic transducer driven to generate ultrasonic vibration, an operation device outputting a signal commanding the transducer to start driving in response to an operator'"'"'s operation, and a driver driving the transducer by supplying current thereto. The apparatus further comprises a controller controlling the driver. The controller controls the driver using selectively a first output control pattern and a second output control pattern. The first output control pattern is set to supply the current of a first current value under control of constant current control in response to the signal from the operation device, while the second output control pattern is set to supply the current of a second current value in response to the signal from the operation device and then the current is reduced in amount as the time counted from starting the supply elapses.

19. A program, of which data is stored in a memory and readable by a computer, applied to an ultrasonic surgical apparatus comprising a treatment device with an ultrasonic transducer driven to generate ultrasonic vibration in response to supply of current;
- an operation device outputting a signal commanding the ultrasonic transducer to start driving in response to an operator'"'"'s operation; and
a driver driving the ultrasonic transducer by supplying the current thereto, whereinthe program making the computer function as means for controlling the driver using selectively a first output control pattern and a second output control pattern, the first output control pattern being set to supply the current of a first current value under control of constant current control in response to the signal from the operation device and the second output control pattern being set to supply the current of a second current value in response to the signal outputted from the operation device and then the current is reduced in amount as the time counted from starting the supply elapses.
- an operation device outputting a signal commanding the ultrasonic transducer to start driving in response to an operator'"'"'s operation; and
-
20. A control device for ultrasonic treatment, comprising:
-
an operation device allowing an operator to selectively command a first control mode and a second control mode, the first control mode allowing ultrasonic energy to be provided to a desired portion of a living body based on a first output control pattern so that a tissue of the desired portion is subjected to coagulation and then incision and the second control mode allowing ultrasonic energy to be provided to a desired portion of a living body based on a second output control pattern so that a tissue of the desired portion is subjected to coagulation; and
a controller controlling generation of the ultrasonic energy based on either the first output control pattern or the second output control pattern, in response to either the first control mode or the second control mode from the operation device.
