When the system is used for the first time after the system has been started, a certain period of time is required to suppress the heat generation of the probe.
Alternatively, the ultrasonic wave cannot be output unless the set flow rate is supplied to the handpiece 31 in advance.

The handpiece 31 for the ultrasonic suction operation is connected to the connecting portion 1 of the output switching device 3 shown in the first embodiment.
When connected to one of 3a to 13c, each connection portion 13a to 13c
Since the switch 13c is switched by the selection switches 14 to 16, after using the ultrasonic suction operation handpiece 31 and once switching to using another handpiece, the water suction device 33 uses the ultrasonic suction operation. When the handpiece 31 is removed, and when the handpiece 31 for ultrasonic suction surgery is selected again by the output switching device 3, it is recognized as newly connected, and the ultrasonic drive signal is transmitted. Before the output, water is sent again.

Therefore, in the present embodiment, after the system is started, it is checked whether or not the ultrasonic suction operation handpiece 31 is used for the first time, and if not, the ultrasonic drive signal is immediately output. Is to start.

Hereinafter, the configuration of the present embodiment will be described with reference to FIG. Connections 13a to 1 of output switching device 3
When the ultrasonic suction operation handpiece 31 is connected to any of the handpieces 3c, the control unit 24 of the output switching device 3 identifies the type of the connected handpiece and transmits the information via the communication cables 12 and 12a. The signal is transmitted to the sound wave output device 2 and the water supply / suction device 33.

A suction tube 32a and a water supply tube 32b extend from the ultrasonic suction operation handpiece 31, and the tubes 32a and 32b are connected to a suction unit 51 and a water supply unit provided in the water supply / suction unit 33. 52.

The water supply / suction unit 33 is provided with a control unit 53 and a switch detection unit 54. The water supply unit 52, the suction unit 51, and the switch detection unit 54 are controlled by the control unit 53.

When one of the setting output foot pedal 8a and the rated output foot pedal 8b provided on the foot switch 8 is depressed, the control unit 53 detects the foot pedal 8a or 8b detected by the switch detection unit 54. A signal is output to the switch detection unit 22 provided in the ultrasonic output device 2, and similarly to the first embodiment, an ultrasonic wave having a predetermined output value is transmitted to the handpiece 12a, 12b or 31 selected by the operator. Output. In this case, a triple water switch is used, and a new water feed pedal is provided.
It is also possible to control only 2 alone.

For example, an ultrasonic suction operation handpiece 31
Is connected to the connection unit 13a (see FIG. 1) of the output switching device 3, the operator turns on the selection switch 14,
When the ultrasonic suction operation handpiece 31 is selected, the distal end of the ultrasonic suction operation handpiece 31 vibrates, and a treatment such as emulsification or crushing is performed on the living tissue.

Simultaneously, an emulsified and crushed living tissue, a cooling liquid, blood, and the like are passed through an opening (not shown) opened at the distal end of the ultrasonic suction operation handpiece 31 via a suction tube 32a. The suction is performed by the suction unit 51.
The suction unit 51 operates at all times after the power supply to the water supply / suction device 33 is turned on.

On the other hand, from the water supply section 52 of the water supply / suction device 33, a cooling liquid (washing liquid) is passed through an opening (not shown) opened at the tip of the ultrasonic suction operation handpiece 31 via a water supply tube 32b. ) Is sent. This water supply section 5
Numeral 2 is set to supply cooling water in synchronization with the ultrasonic output, that is, in synchronization with the ON operation of one of the foot pedals 8a and 8b provided on the foot switch 8.

In this case, when the ultrasonic suction operation handpiece 31 is connected for the first time after the power is turned on, before the ultrasonic suction operation is output to the ultrasonic suction operation handpiece 31, the ultrasonic suction operation is performed. Until the initial setting (flash) for filling the surgical handpiece 31 with the cooling water is restricted, the ultrasonic wave is not output.

At this time, as means for recognizing whether or not the initialization has been completed, the ultrasonic suction operation handpiece 31 is used.
Although it is conceivable to provide a flow rate sensor or the like at the same time, water supply may be simply performed for a certain period of time.

The initial setting is simply performed, and the determination as to whether or not the initial setting has been completed can be made, for example, according to the flowchart shown in FIG.

This routine is repeatedly executed for each of the connecting portions 13a to 13c (see FIG. 1) provided in the output switching device 3 at a predetermined calculation cycle after the power switch is turned on.

That is, when the power switch is turned on,
First, in step S1, an ultrasonic suction surgery handpiece (H
It is checked whether or not the P) 31 is connected. If not, this routine is repeatedly executed to prepare for connection of the ultrasonic aspiration surgical handpiece 31.

The output switching device 3 to be detected is
When a normal handpiece other than the ultrasonic suction operation handpiece 31 is connected to the connection part, this routine is not executed, and the normal ultrasonic output control is performed.

When the ultrasonic suction handpiece 31 is connected to the connection portion of the output switching device 3, the process proceeds to step S2, and the number of the handpiece 31 is stored as the identification flag A.

It is determined whether or not the ultrasonic suction operation handpiece 31 is connected to the connection portion to be detected by the output switching device 3, and the connected handpiece is connected to the ultrasonic suction operation handpiece 31. The determination as to whether or not each of the handpieces 12a to 12c, 31 is provided with a resistor for identification provided at a connection portion provided on each of the handpieces 12a to 12c, 31
A constant current is supplied to the resistor, and the generated voltage is compared with a voltage value set in advance for each type of handpiece.

Thereafter, the process proceeds to step S3, in which one of the foot pedals 8a and 8b of the foot switch 8 is turned on.
It is checked whether or not both are OFF, and if both are OFF, the routine is repeatedly executed, and the routine waits until the foot pedals 8a and 8b are turned ON.

When one of the foot pedals 8a, 8b is turned on, the process proceeds to step S4, where the handpiece 31 for the ultrasonic suction operation connected to the connection portion to be detected is moved. Then, water is supplied for a certain period of time to fill the pipe with cooling water, and after this water supply is completed in a predetermined manner, that is, after the initial setting (flash) for the ultrasonic suction surgical handpiece 31 is completed, the process proceeds to step S5. Then, the ultrasonic output to the ultrasonic suction operation handpiece 31 is permitted.

Thereafter, the flow advances to step S6 to check again whether one of the foot pedals 8a and 8b of the foot switch 8 has been turned ON. If the ON state has been continued, the flow returns to step S5. Also, foot pedals 8a, 8
If b is switched from ON to OFF, step S7
Then, the ultrasonic output to the ultrasonic suction operation handpiece 31 is stopped, and the process proceeds to step S88 to wait until one of the foot pedals 8a and 8b is turned on.

When one of the foot pedals 8a and 8b is turned on, for example, the other handpiece 12
When the ultrasonic suction operation handpiece 31 is used again after using a and 12b, the process proceeds to step S9.
Ultrasound output is permitted, and in step S10, the currently connected handpiece is the ultrasonic suction surgery handpiece 3.
1 is checked by comparing the stored value of the identification flange A with the HP number read from the connected handpiece, and if they match, the ultrasonic handpiece 31 for ultrasonic suction operation is used. Since the initial setting has already been completed, the process returns to step S8, and the ultrasonic output to the ultrasonic suction operation handpiece 31 is permitted until both the foot pedals 8a and 8b are turned off.

As a result, when the ultrasonic suction operation handpiece 31 is used repeatedly without disconnecting it from the connection portion provided in the output switching device 3, only the initial setting is performed first, and thereafter, Since the initial setting has already been completed, the output of the ultrasonic wave is immediately permitted. Therefore, even when the output switching device 3 is used, heat generation of the ultrasonic suction operation handpiece 31 is prevented, and furthermore, the user is prevented from generating heat. In addition, when the ultrasonic suction operation handpiece 31 is connected to the output switching device 3, it is not necessary to perform initial setting, so that the handling is good.

If it is determined in step S10 that the value of the identification flag A does not match the HP number, that is, if another handpiece is connected to the connection portion provided in the output switching device 3 and being detected. If it is determined that 12a and 12b are connected, the process proceeds to step S11, in which the ultrasonic output is stopped, and the routine exits.

In this case, for example, as shown in FIG. 6, the water supply / suction unit 33 is provided with a flush time setting unit 34, an ultrasonic output setting unit 35, a water supply amount setting unit 36, and a suction pressure setting unit 37. When the ultrasonic output setting value is large, the heat generation amount of the ultrasonic suction surgical handpiece 31 also becomes large, so that the flash time and the flash time The water supply amount at that time may be automatically increased. At this time, if the maximum water volume is restricted by the flow path resistance of the ultrasonic suction handpiece 31, the flush time is lengthened.

Reference numerals 34a to 37a in the figure denote display units for displaying the set values of the setting units 34 to 37, and 34b to 37b.
b denotes an up / down switch for manually setting the set amount of the setting units 34 to 37; 38 denotes a pinch valve for connecting a suction tube 32a extending from the ultrasonic suction operation handpiece 31; Controls the closing / opening.

Reference numeral 39 denotes a water supply pump for connecting the water supply tube 32b, and reference numeral 40 denotes an ultrasonic output connector. When the water supply suction device 33 is used alone, this connector 4
0 is directly connected to the ultrasonic suction operation handpiece 31.
