Abstract

An ultrasonic operating apparatus of the present invention includes an apparatus main body having a vibration driving circuit for generating a driving signal to apply ultrasonic vibrations to a vibration generating portion of a hand piece and having a control portion for generating the driving signal and for systematically controlling the apparatus. An operating and display panel and a water supply pump are arranged to an outer surface of the apparatus main body, and the driving signal is supplied to the hand piece via a connector. Until a user carries out a correct processing routine, the control portion does not perform the above control operation even though the user may execute another control operation. Further, the control portion controls an operation so that an incorrect processing routine is notified to the user on the operating and display panel.

Claims

1. An ultrasonic operating apparatus comprising:

a hand piece having a vibration generating portion for generating ultrasonic vibrations;

an ultrasonic operating tool having a probe for transmitting the ultrasonic vibrations to the organ;

a signal generating portion which generates a driving signal for applying the ultrasonic vibrations to the vibration generating portion of the hand piece;

a control portion which controls the driving signal and systematically controls the apparatus;

a detecting portion which detects an abnormal state of the ultrasonic operating tool; and

notifying means which notifies the abnormal state of the ultrasonic operating tool,

wherein the control portion controls an operation so as to prevent the control operation even if another control operation is executed until a user copes with the abnormal state by a correct processing routine and the notifying means sends a notification indicating the incorrect processing routine to the user.

2. An ultrasonic operating apparatus according to claim 1, wherein the control portion sends a notification by displaying a warning of the abnormal state of the ultrasonic operating tool upon detecting the abnormal state, different from a displaying operation of another abnormal state.

3. An ultrasonic operating apparatus according to claim 1, further comprising:

water supply means which supplies water from a near portion of the probe in the ultrasonic operating tool,

wherein the water supply means is operated only at a timing for operating a water supply function.

4. An ultrasonic operating apparatus according to claim 1, wherein an apparatus main body comprises the signal generating portion, the control portion, the detecting portion, and the notifying means, the apparatus main body has a water supply pump for supplying water via a tube which connects the ultrasonic operating tool to a water supply passage in the hand piece and a guide mechanism for absorbing the difference depending a coping process upon attaching the tube to the water supply pump.

5. An ultrasonic operating apparatus according to claim 1, wherein the control portion performs initial check of an apparatus main body, and sends a notification indicating an abnormal state only upon detecting it by using the notifying means.

6. An ultrasonic operating apparatus according to claim 5, wherein when the abnormal state is found, the control portion determines whether or not the user can cope with the abnormal state and, when it is determined that the user can cope with it, sends a notification indicating a processing routine for coping with the abnormal state by the notifying means.

7. An ultrasonic operating apparatus according to claim 6, wherein when it is determined that the user cannot cope with the detected abnormal state, the control portion sends a notification indicating that the user cannot cope with the detected abnormal state by the notifying means.

8. An ultrasonic operating apparatus according to claim 1, further comprising:

a foot switch for controlling the driving signal of the signal generating portion,

wherein the control portion performs initial check of an apparatus main body, when the abnormal state is not found, determines whether or not the foot switch and the hand piece are connected to the apparatus main body and, when it is determined that they are not connected, sends a notification indicating which of the foot switch and the hand piece is not connected to the apparatus main body to the user by using the notifying means.

9. An ultrasonic operating apparatus according to claim 1, further comprising:

a foot switch for controlling the driving signal of the signal generating portion,

wherein the control portion determines whether the foot switch is ON or OFF and, when it determines that it is OFF, the control portion stops the generation of the driving signal from the signal generating portion.

10. An ultrasonic operating apparatus according to claim 9, wherein the control portion monitors whether or not the ultrasonic operating tool is abnormal when the foot switch is ON and, when it is monitored that it is abnormal, the control portion sends a notification indicating the abnormal state until a user copes with the abnormal state.

11. An ultrasonic operating apparatus according to claim 9, wherein the control portion monitors whether or not the ultrasonic operating tool is abnormal when the foot switch is ON and, when it is monitored that it is abnormal, the control portion stops the generation of the driving signal from the signal generating portion and sends a notification indicating the abnormal state by the notifying means.

12. An ultrasonic operating apparatus according to claim 10 or 11, wherein when the abnormal state of the ultrasonic operating tool is solved, the control portion enables the signal generating portion to output the driving signal.

13. An ultrasonic operating apparatus according to any one of claims 1 to 12, wherein the detecting portion includes a PLL circuit for making a resonant frequency of the driving signal supplied to the ultrasonic operating tool constant and, when the PLL circuit changes the resonant frequency, the detecting portion detects the abnormal state of the ultrasonic operating tool.

14. An ultrasonic operating apparatus according to any one of claims 1 to 12, wherein the notifying means includes a display portion for visual notification and a sound production portion for auditory notification, in order to specify the abnormal state of the ultrasonic operating tool.
