An ultrasonic treatment tool that can select and combine one from each of a plurality of types of probe groups, and a driving device that detachably connects the ultrasonic treatment tool and supplies drive power to the ultrasonic transducer. In the ultrasonic treatment apparatus, the ultrasonic treatment instrument has an identification signal output unit that outputs a handpiece identification unit that is an analog electric signal and indicates a type of the handpiece, and the driving device includes the handpiece. Handpiece identification means for reading an identification signal, and identifying the kind of the connected handpiece from the read handpiece identification signal; Activating means for activating a reading operation of the handpiece identification signal of the identifying means.

Then, these handpieces and probes are combined according to the purpose of treatment and operation, and used by connecting to a driving device. Each handpiece is connected with a connector for connecting to a drive device, and further provided with identification means for identifying the type of the handpiece. Therefore, by combining the handpiece and probe according to the application of treatment and surgery, and connecting the connector to the drive, the drive identifies the handpiece, and the ultrasonic vibrator built in the handpiece is optimal. Driven under conditions.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Kind. As shown in FIG. 2, the handpieces 1a and 1b have an ultrasonic vibrator 2 built therein. A plurality of types of probes 4a to 4c are selectively connected to the horn 3 of the ultrasonic transducer 2. The probes 4a to 4c are of a short type, a bent type, a long type, and the like, and are selected according to the purpose of treatment and operation and fastened to the handpieces 1a and 1b with screws or the like. One end of a cable 5 as a signal transmission unit is connected to the handpieces 1a and 1b, and a connector 6 is connected to the other end.
Is provided. Reference numeral 7 denotes a driving device, which is mounted on the moving carriage 8. The drive device 7 has a connector receiver 9 to which the connector 6 is connected and a roller pump for water supply.

The water supply roller pump 10 is connected to a liquid supply bottle 15 such as a saline solution via a water supply pipe 14 and to the handpieces 1a and 1b via a water supply tube 16. The drive device 7 is provided with a foot switch 17 operated by an operator.

Then, handpieces 1a and 1b are selectively connected to the driving device 7, and the probe 4a is connected to these handpieces 1a and 1b.
To 4c are selectively connected. The input power amounts differ between the handpieces 1a and 1b. Specifically, since the maximum value of the current flowing into the internal ultrasonic transducer 2 is different, the type of the handpieces 1a and 1b can be identified by the identification means 18 described later. Among the probes 4a to 4c, a short probe 4a is used for general surgery, a bent probe 4b is used for microscopic surgery such as brain surgery, and a long probe 4c is used for transendoscopy. When the bent type probe and the long type probe 4b and 4c are used, the impedance characteristics during driving are different from those of the short type probe 14a. That is, the bending type and the long type probes 4b and 4c have a larger ultrasonic vibration load than the short type probe 4a for the ultrasonic vibrator 2, and require a large electric power. Therefore, it is necessary to drive at a high voltage. In addition, the bending type and the long type probes 4b and 4c generate a larger amount of heat when ultrasonically oscillating them than the short type probe 4a. There is.

The following means are provided in order to cope with driving characteristics that differ depending on the types of the handpieces 1a and 1b and the probes 4a to 4c used in this way and to cope with changes in various settings.

In both the case of the resistance element 18a and the Zener diode 18b, the connector 6 has an identification terminal 20 projecting in parallel with the signal transmission terminal 19, and is connected to the connector receiver 9 of the drive device 7.

Alternatively, the identification means 18 may determine whether or not the handpieces 1a and 1b are connected to the driving device 7. Further, when the ultrasonic vibrator 2 differs depending on the type of the handpieces 1a and 1b, signal transmission in the connector 6 is performed as shown in FIG. The arrangement of the terminals 19 may be changed.

Next, the drive device 7 will be described. The drive device 7 is configured as shown in FIG. Reference numeral 21 denotes a control unit. The control unit 21 is connected to a drive circuit 22. The drive circuit 22 is connected to a detection circuit 23 for detecting a voltage V and a current I of the drive signal. The detection circuit 23 is connected to a primary side of an output transformer 25 via a switching relay 24. The secondary side of the output transformer 25 is connected to the contact 26 of the connector receiver 9. Further, the control section 21 is connected to the contact 28 of the connector receiver 9 via the identification circuit 27 of the identification means 18.

Further, the control unit 21 outputs a control signal to the electromagnetic valve 29 provided in the middle of the water supply roller pump 10 and the suction tube 13, and outputs a display signal to the display panel 30.

According to the ultrasonic therapy apparatus configured as described above, when the connector 6 of one handpiece 1a to which the probe 4a is fastened is connected to the connector receiver 9 of the driving device 7, the signal transmission terminal 19 is connected to the contact 29 of the connector receiver 9. Connected to the terminal 20 for identification.
Is connected to the contact 28. Then, the resistance element 18 a as the identification means 18 is connected to the identification circuit 27, and the ultrasonic transducer 2 is connected to the drive circuit 22.

When the control unit 21 first instructs the drive circuit 22 to drive the handpiece 1a with a weak signal, the voltage and current detection results differ depending on the type of the probes 4a to 4c fastened to the handpiece 1a. Is used to identify the type of the probes 4a to 4c. Specifically the bending type and the long probe. 4b, 4c is can be identified by the value of Z ₁ = V / I is larger than the Z ₂ = V / I of the short type probe 4a. That is, the impedance Figure 5 the vertical axis Z, a characteristic when taking frequency f on the horizontal axis, and FIG. (A) is bent-shaped and the long probe 4b, 4c are of the impedance Z _1, FIG (b), the impedance of the short type of probe 4a is Z _2, when comparing this, Z _1> relationship Z ₂ appears.

As shown in FIG. 6, a resonance point detection circuit 31 is provided between the drive circuit 22 and the switching relay 24 so that the resonance point frequency differs depending on the type of the probes 4a to 4c. Design and manufacture 4a-4c. As shown in FIG. 7 (a) (b), can also be identified by detecting the resonance point frequency f _1, f ₂ are different things depending on the type of probe 4 a to 4 c.

When the driving device 7 identifies the types of the handpieces 1a and 1b and the probes 4a to 4c as described above, the result of the type determination of the handpieces 1a and 1b obtained by the identification circuit 27 is input to the control unit 21. The control unit 21 commands the drive circuit 22 to regulate the maximum value of the electric power input to the ultrasonic transducer 2. Further, based on the result of the type determination of the probes 4a to 4c, the control unit 21 operates the switching relay 24 as if changing the winding ratio of the output transformer 25, thereby coping with the difference in the driving characteristics (impedance). , And can be driven by matching. Further, the setting of the water supply roller pump 10 is changed and optimized. Each of these settings changes
This is performed in a setting routine shown in FIG. First, connector 6
Is connected to the connector receiver 9, it is determined in step S1 whether the handpiece 1a or 1b is connected, and "YES" is determined.
The setup switch 30a on the display panel 30
push. In step S2, it is determined whether or not the setup switch 30a is turned on. If "YES" in step S2, the process proceeds to step S3 to determine the type of the handpieces 1a, 1b. Then, the control unit 21 changes each setting based on the result of the type determination of the handpieces 1a and 1b. Next, the process proceeds to step S4, where the types of the probes 4a to 4c are determined. Then, the control unit 21 changes each setting based on the result of the type determination of the probes 4a to 4c.

When the types of the handpieces 1a and 1b and the probes 4a to 4c are identified and each setting is completed, a display indicating that the setup is completed is displayed on the display panel 30. Thereafter, by operating the foot switch 17, each operation of ultrasonic oscillation, water supply, and suction can be controlled.

According to this embodiment, the handpieces 1a and 1b and the probes 4a to 4c can be used in a wide variety of ways and can be used by the common drive device 7 according to the purpose of treatment and surgery.
Therefore, it can be applied to various surgical operations.

However, when the handpieces 1a and 1b are replaced, each condition such as the amplitude setting and the water supply amount setting must be changed and set. To cope with this, it is necessary to provide a means for storing each setting for each of the handpieces 1a and 1b.

FIGS. 9 to 12 show an ultrasonic therapy apparatus having means for storing the types of handpieces 1a and 1b in an external storage device such as an IC memory card on an operation panel 40 of the drive device 7, and an embodiment of the present invention. The same components are denoted by the same reference numerals, and description thereof is omitted. The operation panel 40 shown in FIG. 9 is provided with a power switch 41 for turning on / off the power of the driving device 7, a suction mode switch 42 for continuously performing suction, and a synchro switch 43 for performing suction operation simultaneously with ultrasonic oscillation. ing. 44
Is a level meter for setting the amplitude of ultrasonic oscillation, and is provided with a down switch 44a and an up switch 44b. Reference numeral 45 denotes a level meter for setting the amount of water supply, which is provided with a down switch 45a and an up switch 45b. In addition, a normal switch for switching the ultrasonic output pulse mode
46 is a mode for continuously outputting ultrasonic waves at a constant value, a first pulsation switch 47 is a mode for turning on and off the ultrasonic output at regular intervals, and a second pulsation switch 48 is a first pulsation switch. In this mode, the ultrasonic output is turned on and off at a cycle different from 48.

Further, the operation panel 40 is provided with a card insertion slot 50 for inserting an IC memory card 49, and a memory switch 51 for storing the information in the IC memory card 49.

FIG. 10 shows the internal structure of the drive unit 7, in which the microprocessor unit 52 is connected to a display switch 53 of the operation panel 40 and to a control circuit 54 for controlling the ultrasonic output of the ultrasonic vibrator 2. Have been. The control circuit 54 sends the ultrasonic signal to the amplifier 55, and the amplifier 55 amplifies the ultrasonic signal. The amplified signal is applied to the transformer 56, and the ultrasonic transducer 2 connected to the secondary side of the transformer 56
Is driven. The IC memory card 49 is connected to the microprocessor unit 52 and exchanges information. The handpiece type detection circuit 57 is a microprocessor unit.
Connected to the microprocessor 52, the presence / absence and type of the handpieces 1a and 1b at that time are transmitted to the microprocessor unit 52.

FIG. 11 shows an operation routine of the driving device 7. When the power switch 41 is turned on, the presence or absence of the handpiece is detected in step S1, and when "NO", the setting at the time of the previous power-off is set, and when "YES", In step 2, it is checked whether the IC memory card 49 is connected. If “YES” in the step 2, the panel setting corresponding to the handpiece connected at that time is set to the IC memory card 49.
Causes the microprocessor unit 52 to read and change the panel settings. If "NO" in the step 2, the setting corresponding to the handpiece connected at that time is read out from the microprocessor unit 52 to perform the panel setting.

FIG. 12 shows an operation routine of the driving device 7 when the power switch 41 is already turned on. When the handpiece is connected, it is checked in step S1 whether the IC memory card 49 is connected. "YES" in step S1
In this case, the microprocessor unit 52 reads the panel setting corresponding to the handpiece connected at that time by the IC memory card 49, and changes the panel setting. If "NO" in the step S1, the setting corresponding to the handpiece connected at that time is read from the microprocessor unit 52 to perform the panel setting.

When the handpiece is connected, the IC memory card 49 is connected, and when the memory switch 51 is turned on, the panel setting at that time is stored in the IC memory card 49 together with the type of the handpiece. For this reason, if the number of operators of the IC memory card 49 is prepared, the personal preference of the operator can be saved. When there is no IC memory card 49, the data is stored in the microprocessor unit 52 corresponding to the handpiece. At this time, the handpiece connected when the power switch 41 was turned off and the panel setting at that time are stored in combination. When the handpiece is replaced, the setting for the new handpiece is read out to change the panel setting, and the setting before the change and the type of the handpiece are stored in combination.

By the above operation, even when various handpieces are used while being replaced, the panel settings automatically correspond to the handpieces each time, and the usability is greatly improved. In addition, even when a single driving device 7 is used by a plurality of surgeons due to the difference in giving the IC memory card 49 to the surgeon, the settings of the surgeon can be stored. Usability as if it were a dedicated device can be obtained.

As described above, when various probes are used in combination with the handpiece, it is necessary to obtain a desired tip amplitude for each probe. Therefore, conventionally, the connecting portion and the vibration transmitting portion constituting the probe are changed for each probe.

However, if the connecting part and the vibration transmitting part that make up the probe were changed for each probe, parts could not be shared, which caused a cost increase.However, the amplitude value up to the connecting part was the same for each probe, The above-described problem can be solved by making the vibration transmission unit common and obtain a desired amplitude and a desired tip shape.

That is, as shown in FIG. 13, a first probe 61 and a second probe 62 are used interchangeably for the ultrasonic transducer 60. The ultrasonic vibrator 60 is configured by arranging a plurality of piezoelectric elements 65 between a horn 63 and a backing plate 64 and tightening them with bolts 66. Electrodes 67 are provided between the piezoelectric elements 65, and the electrodes 67 are connected to a driving power supply (not shown).
The bores of the horn 63 and the bolt 66 are formed as a suction passage 68, and are connected to a suction pump (not shown). Note that 69
Is the cover. The ultrasonic vibrator 60 is configured as one resonance system, and resonates and vibrates. At that time, the piezoelectric element 65
It vibrates to A ₀ , the amplitude is expanded by the amplitude expansion rate M ₁ of the horn 63, and is transmitted to the end of the horn 63 with the amplitude A ₀ × M ₁ . The first probe 61 is composed of a vibration transmitting portion 71 and the connecting portion 70 and the amplitude magnification M3 that the amplitude magnification factor M _2.
The lumen of the vibration transmitting section 71 is connected to the suction path 68 of the ultrasonic vibrator 60 as a suction path 72. Then, the first probe 61 and the ultrasonic transducer 60 are detachably connected by screws 73a and 73b.

The amplitude A ₀ × M ₁ at the end of the horn 63 is A ₀ × M ₁
× M ₂ and transmitted to the vibration transmission unit 71, and A ₀ × M ₁ × M ₂
× a size of M _3. This is given to the tissue as the tip amplitude A ₁ = A ₀ × M ₁ × M ₂ × M ₃ of the first probe 61, and the tissue is emulsified and aspirated. Since the first probe 61 uses a straight titanium alloy thin pipe as the vibration transmitting unit 71, the amplitude expansion rate M ₃ = 1 in the vibration transmitting unit 71.

In the first probe 61, the fatigue failure is most likely to occur in terms of strength. There is a portion located at the node of vibration of the titanium alloy thin pipe constituting the vibration transmitting portion 71. it is important to select the amplitude magnification factor M _2, also the amplitude does not occur destruction to the vibration transmitting portion 71 of the tissue emulsification, the desired thin pipe of the vibration transmitting portion 71 so that the tip amplitude for the suction It is necessary to select the thickness, material, and the like.

The second probe 62 uses a common connection part 74 with the first probe 61, and has a vibration transmitting part 75 connected to the end thereof. The vibration transmitting section 75 includes a pipe section 76 and a distal end tip 77 integrally connected to the distal end thereof by welding. A distal tip 77 the amplitude magnification factor M _4, also has an amplitude magnification of M ₄ as a whole vibration transmitting portion 75. Accordingly, the tip amplitude A ₂ of the second probe 62 becomes _{A 2 = A 0 × M 1} × M 2 × M 3 × M 4.
The second probe 62 is used when a tip amplitude larger than that of the first probe 61 is required. The length of tip 77 is It is.

Also, the total length of the first and second probes 61 and 62 is It is.

As described above, since probes having different tip amplitudes can be obtained by using the common connecting portion, components can be shared and cost can be reduced. The vibration transmitting part is integrally connected to the tip of the pipe and its tip by welding, but the welding is TIG, laser, electron beam welding, diffusion welding, etc., which increases the overall strength of the probe. Therefore, when the hardening effect treatment is performed in a vacuum, the effect is large.

Furthermore, removal of the oxide film on the inner and outer surfaces of the vibration transmission unit,
In order to remove cracks and scratches and increase the strength, it is highly effective to perform polishing by fluid polishing, sand blasting, buffing, electric field polishing, electric field compound polishing, or the like.

As the material, a material having a low Young's modulus such as a titanium alloy or an aluminum alloy such as duralumin is preferably used for the connection portion, the vibration transmission portion, and the tip.

Handpieces are also used depending on the application, but as shown in FIG. 14, a handpiece 80 and a probe 81 are used.
Determines the tip vibration amplitude value acting on the tissue. Handpiece 80 for handling any combination, handpiece as a device on the probe 81 side
In the combination of the ultrasonic vibrator 80a, the horn 80b and the probe 81 in the 80, the various handpieces 80 and the various The combination of the probes 81 is determined.
In other words, M _Tn : Amplitude expansion rate of handpiece M _Pn : Amplitude expansion rate of probe _{Mn max} : Maximum amplitude determined by usage of various handpiece probes That is, the vibration amplitude of the ultrasonic vibrator 80a itself is
Although the tip amplitude is enlarged by 0b and the probe 81, the amplitude value to be generated by the ultrasonic transducer 80a itself is constant by adopting a configuration that satisfies the above expression by any combination. I did it. As a result, the drive device only has to work so as to control the amplitude of the ultrasonic transducer 80a itself. Also, handpiece 80
And the amplitude value of the ultrasonic transducer 80a may be different depending on the type of the handpiece 80.

Further, in the above-described ultrasonic therapy apparatus, it is general that the excised diseased tissue is removed by suction, but this suction means includes a suction pump, a suction tissue collection container, and a suction control unit. ing. In addition, suction is always performed from a probe connected to the handpiece regardless of ON / OFF of the ultrasonic oscillation. However, if suction is always performed, when the distal end of the probe is separated from the diseased tissue, there is a possibility that the suction force may damage normal tissue. Therefore, in order to solve the above-mentioned problem,
The ultrasonic therapy apparatus shown in FIGS. 15 to 17 was constructed. Since this ultrasonic therapy apparatus is basically the same as FIG. 1, the same components are denoted by the same reference numerals and description thereof will be omitted. Suction tube connecting handpiece 82 and tank 83 for aspirated material
An opening / closing valve 85 is provided at 84, a branch tube 86 opening to the atmosphere is connected to a suction tube 84 between the opening / closing valve 85 and the handpiece 82, and an electromagnetic valve 87 is connected to the branch tube 86.
Is provided.

Then, when the foot switch 17 is turned on and in the ultrasonic oscillation state, the solenoid valve 87 is in the closed state, but the on-off valve 85
Is in a valve open state. When the foot switch 17 is turned off,
As shown in FIG. 17, the on-off valve 85 is closed and the suction tube 84 is shut off, but since the solenoid valve 87 opens for a certain period of time, the inside of the handpiece 82 is exposed to the atmosphere via the branch tube 86. In communication, the negative pressure at the tip of the handpiece 82 is released. Therefore, the handpiece 84 can be quickly and safely separated from the tissue.

The hospital operating room is also equipped with powerful suction equipment. Therefore, by connecting the suction tube 84 to suction equipment in the hospital instead of the suction pump 11, suction can be performed without providing a suction pump in the ultrasonic therapy apparatus. in this case,
Since the opening / closing valve 85 is provided, the opening / closing control of suction can be performed regardless of which equipment is used. The opening and closing of the suction tube 84 can be set according to the intended use, such as a mode in which suction is performed in conjunction with ultrasonic oscillation or a mode in which suction is always performed.

[Effects of the Invention] As described above, the present invention provides a plurality of types of probes selectively mounted on a plurality of types of handpieces, and a driving device for driving an ultrasonic vibrator. Since a signal transmission unit having means for identifying a piece is provided, and the handpiece is connected to the driving device to perform signal transmission with the driving device, the handpiece can be connected to the driving device only by connecting the handpiece to the driving device. There is an effect that the handpiece and the probe can be identified in a wide variety of handpieces and probes according to the purpose of treatment and operation, and can be used with a common drive device.

Furthermore, by using the handpiece identification signal as an analog electric signal, even if the types of handpieces are extremely varied depending on the purpose of treatment or surgery, each individual can be identified. In this case, when the high-frequency part of the driving device or the device used in combination operates, the noise may be mixed into the analog electric signal and an erroneous handpiece identification signal may be read. Therefore, it is possible to read the handpiece identification signal after confirming that the high-frequency unit and the like are not operating, and thus it is possible to eliminate an erroneous recognition of the handpiece.
