Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic applicator applied to an ultrasonic treatment apparatus for irradiating a treatment target site with ultrasonic waves for treatment.

[0002]

2. Description of the Related Art As a conventional technique, there has been known a technique of irradiating continuous ultrasonic waves to heat a treatment target portion in an ultrasonic irradiation area. As means for generating these ultrasonic waves, for example, a piezoelectric method using a piezo element, an electromagnetic conversion method, and the like have been used.

[0003] It is known to apply these prior arts to, for example, an ultrasonic treatment apparatus, and a therapeutic ultrasonic wave generated by an ultrasonic generator from outside the body of a patient to be treated is applied to the inside of the body. A configuration is provided for irradiating a diseased tissue or the like, which is a treatment target site.

[0004] Further, by providing a focusing means for focusing the ultrasonic waves to be irradiated in the above-mentioned ultrasonic therapy apparatus, it is also possible to focus on an intended part, and to focus on the lesion part to be treated by focusing the ultrasonic waves. It is made to tie. Due to the focusing of the ultrasonic waves, a temperature rise occurs at the focal point due to the concentration of the ultrasonic energy. Since the temperature of the treatment target site can be instantaneously heated to 80 degrees Celsius or more by this temperature rise, a lesion such as a tumor can be treated by degenerating tissue.

[0005] For such treatment, a transducer for generating ultrasonic waves, an ultrasonic wave propagation medium that propagates ultrasonic waves to make close contact with a subject, and a treatment target site of the subject are observed. An ultrasonic treatment apparatus equipped with an ultrasonic applicator including an ultrasonic probe for obtaining an ultrasonic tomographic image is used. The position of the ultrasonic applicator that is in close contact with the subject is fixed by a holding and moving operation mechanism such as an operation arm. To move the contact position, the ultrasonic applicator is moved by driving the operation arm.

The control of irradiation or non-irradiation of the therapeutic ultrasonic waves is performed through a control panel or the like provided in the main body of the ultrasonic therapeutic apparatus, and the control of the operation arm can be performed at the same time. The control of the ultrasonic wave propagation medium is also performed by this control panel. Water is generally used as the ultrasonic wave propagation medium, and is filled and held between the ultrasonic wave emitting surface of the vibrator in the ultrasonic wave applicator and a rubber film for closely adhering to the subject. This ultrasonic wave propagation medium also has a role as a cooling medium for the vibrator. For example, the ultrasonic wave propagation medium is circulated, and the flowing speed or the water temperature is controlled to control the vibrator during operation. Cooling fever.

[0007] An ultrasonic probe for observing a treatment target site of a subject is arranged in the ultrasonic propagation medium. With this ultrasonic probe, an ultrasonic tomographic image effective for confirming the progress of treatment at the treatment target site, the state of tissue change, the irradiation target site, and the like is obtained. Ultrasonic probe
It is arranged near the center of the spherical shell-shaped transducer to obtain focused ultrasound, and can render an ultrasonic tomographic image near the focal point of the focused ultrasound located immediately below.

[0008]

When performing an ultrasonic treatment using the above-described ultrasonic treatment apparatus, the ultrasonic applicator is fixed to the operation arm, so that the ultrasonic applicator can be freely moved with respect to the subject. It is difficult to finely adjust the contact position and the irradiation position, and a lot of space dedicated to the ultrasonic treatment apparatus is required.

Further, the control of irradiation or non-irradiation of the therapeutic ultrasonic waves must be performed by a control panel provided in the main body of the ultrasonic therapeutic apparatus, and the operability is not good.

[0010] Further, since the ultrasonic probe for observation is arranged near the focal point where the focused ultrasonic wave is reflected when irradiating the ultrasonic wave for treatment, the temperature rises with the lapse of time, and as a result, the ultrasonic wave increases. There was a possibility that a failure occurred in the acoustic wave probe.

In addition, since it is not possible to detect a rise in temperature near the ultrasonic probe, even if a rise in temperature occurs, a focused ultrasonic wave for treatment is continuously generated, and irradiation of the focused ultrasonic wave can be stopped. Did not.

The present invention has been made in view of the above problems, and is small in size and light in weight and has good operability. It is possible to move the ultrasonic applicator by gripping, and to irradiate / stop the therapeutic ultrasonic waves. Of the ultrasonic applicator with the control means of the ultrasonic wave propagating medium, and the sub-control means operated by the foot, etc., and the ultrasonic applicator is provided with the elevating means of the ultrasonic probe. Ultrasonic treatment which can prevent temperature rise by moving away from the focal point during irradiation of therapeutic ultrasonic waves, and can control the irradiation of therapeutic ultrasonic waves by detecting the temperature rise of the ultrasonic probe by providing temperature detection means It is an object to provide an applicator for a device.

The apparatus applicator, comprising: irradiation control means for controlling irradiation of therapeutic ultrasonic waves; and probe raising means for raising the ultrasonic probe from a predetermined position during irradiation of therapeutic ultrasonic waves, The applicator for an ultrasonic treatment apparatus is a solution.

A temperature detecting means for detecting a temperature rise due to irradiation, and a control means for controlling irradiation of the therapeutic ultrasonic wave when a detected value of the temperature detecting means exceeds a predetermined value. The solution is an applicator for a sonic therapy device.

According to a fourth aspect of the present invention, the control means stops the irradiation of the therapeutic ultrasonic wave when the detected value of the temperature detecting means exceeds a predetermined value. Item 3 is an applicator for an ultrasonic treatment apparatus described in Item 3.

According to a fifth aspect of the present invention, there is provided an ultrasonic treatment apparatus which has an ultrasonic probe capable of obtaining an ultrasonic tomographic image for observing a treatment target site, and which is used by holding it by hand. In the applicator, the ultrasonic probe is disposed apart from the body surface contact surface of the ultrasonic treatment apparatus applicator.

With this configuration, the therapeutic ultrasonic wave reflected during the irradiation of the therapeutic ultrasonic wave is not irradiated to the ultrasonic probe for drawing an image, and the ultrasonic probe is moved upward from a predetermined observation position. As a result, unintended heating of the ultrasonic probe can be prevented.

Further, even if unintended heating of the ultrasonic probe occurs, the temperature change can be detected by the temperature detecting means, so that irradiation of the therapeutic ultrasonic wave can be stopped when the temperature exceeds a predetermined temperature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic diagram for explaining a configuration of an ultrasonic therapy applicator according to a first embodiment of the present invention.

This ultrasonic treatment apparatus applicator comprises an ultrasonic applicator 1 used in close contact with a subject,
A transducer 2 for irradiating therapeutic ultrasonic waves, an ultrasonic probe 3 for observing a treatment target site where therapeutic ultrasonic waves are focused and focused by an ultrasonic tomographic image, and a temperature of the ultrasonic probe 3 , A system console 5 for inputting an instruction for controlling the operation of the ultrasonic therapy apparatus, and an ultrasonic probe position control apparatus for controlling the elevation position of the ultrasonic probe 3 6
A temperature detecting device 7 that captures an electrical change from the temperature sensor 4 as a temperature change; a focused ultrasonic generating source driving device 8 that drives the vibrator 2 to generate a therapeutic ultrasonic wave; , An ultrasonic diagnostic apparatus 9 to which an ultrasonic probe 3 is connected to render an ultrasonic tomographic image, and a base material 10 which is a structure of the ultrasonic applicator 1 and supports the transducer 2 and the like
A coupling 11 arranged on the body surface contact surface of the ultrasonic applicator 1 and in close contact with the body surface of the subject; an elevating means 12 for elevating and lowering the ultrasonic probe 3; And an ultrasonic wave propagating medium 13 for transmitting an ultrasonic wave for drawing an image.

In order to bring the ultrasonic applicator 1 into contact with the body surface of the subject so as to focus the ultrasonic wave on the part to be treated, the ultrasonic probe connected to the ultrasonic diagnostic apparatus 9 is first used. 3 is used to draw an ultrasonic tomographic image of the treatment target site. The ultrasonic applicator 1 is positioned based on the ultrasonic tomographic image, and the focal point f1 is adjusted to the target treatment target site. The ultrasonic probe 3 is located near the center of the vibrator 2 when observing the treatment target site by rendering the ultrasonic tomographic image, and is capable of rendering a good ultrasonic tomographic image on a vertical line of the focal point f1. This is the position near the body surface. As described above, even if the ultrasonic probe 3 is brought as close as possible to the body surface, there is no problem of image quality deterioration in the vicinity of the ultrasonic probe 3 when obtaining an ultrasonic tomographic image. This is because the observation target site is located inside from the body surface, and the drawing ability of the body surface portion does not matter. It is to be noted that the ultrasonic diagnostic apparatus 9 does not necessarily need to be integrally formed with the ultrasonic therapeutic apparatus, and it is sufficient to use a separate ultrasonic diagnostic apparatus.

Next, the operation of the system console 5 causes the ultrasonic probe 3 to move to the ultrasonic probe position controller 6.
The ascending / descending means 12 whose operation is controlled in the above-described manner. This is for preventing the ultrasonic probe 3 from being heated by the transducer 2 irradiating therapeutic ultrasonic waves by being pulled up in the vertical direction with respect to the previous image observation position. The elevating means 12 may include a moving distance detecting device (not shown) so that the focused position of the therapeutic ultrasonic wave can be recognized on an image monitor screen (not shown). Thereby, the distance between the focal position due to the focusing and the ultrasonic probe 3 can be measured, which helps to grasp the position accurately. The heating of the ultrasonic probe 3 is performed by using the therapeutic ultrasonic waves from the vibrator 2.
The therapeutic ultrasonic wave reflected and returned from the boundary surface between the body surface and the coupling 11 or other small bubbles or air forms a focus near the center of the transducer 2 where the ultrasonic probe 3 is located. This is because

The ultrasonic probe 3 is located at this unintended focus.
However, particularly when the distal end portion is located, the heating by the focusing of the therapeutic ultrasonic wave affects an ultrasonic transducer (not shown) disposed at the distal end portion. In order to avoid this effect, the ultrasonic probe 3 is moved by the elevating means 12
Arrow k in the figure from the focal position where the reflected therapeutic ultrasonic wave connects
Keep away as shown by. After moving away in this way, the ultrasonic waves for treatment are irradiated from the transducer 2 to the treatment target site, and the intended predetermined ultrasonic treatment can be performed.

The ultrasonic probe 3 has a temperature sensor 4 near its tip. The temperature sensor 4 is connected to a temperature detection device 7 and detects a change in electrical characteristics of the temperature sensor 4 due to a change in temperature as a temperature change. It should be noted that a temperature detecting element such as a thermocouple or a thermistor can be used as the temperature sensor 4, and a plurality of temperature sensors can be provided instead of one. When the detected value detected by the temperature detecting device 7 exceeds a predetermined value set in advance, a driving stop signal may be sent to the focused ultrasonic generating source driving device 8 to stop driving or reduce the output. This predetermined value is set lower in anticipation of safety than the temperature at which the influence of the temperature rise of the ultrasonic probe 3 starts to occur, and when the predetermined value is detected, the driving of the vibrator 2 is stopped, and Ultrasonic probe 3 by rising
Can be prevented.

The relationship between the temperature sensor 4 and the above-mentioned elevating means 12 may be such that both are used in combination so that the ultrasonic probe 3 always rises with the irradiation of the therapeutic ultrasonic wave. The determination may be made by the user regardless of the irradiation of the therapeutic ultrasonic wave. In the temperature detection by the temperature sensor 4, for example, the temperature may be constantly monitored irrespective of the elevation of the elevating means 12, and irradiation of the therapeutic ultrasonic wave may be stopped when the temperature exceeds a predetermined value regardless of the state. In addition, the elevation of the ultrasonic probe 3 can be controlled based on the detected value, and the elevation of the ultrasonic probe 3 can be performed irrespective of irradiation of therapeutic ultrasonic waves.

FIG. 2 is a schematic diagram for explaining a configuration of an ultrasonic therapy apparatus applicator according to a second embodiment of the present invention.

The applicator for an ultrasonic therapy apparatus is an ultrasonic applicator 17 for transmitting a therapeutic ultrasonic wave in close contact with the body surface of a subject, and an ultrasonic diagnostic apparatus for observing a treatment target site. The apparatus 9, an ultrasonic probe 18 connected to the ultrasonic diagnostic apparatus 9 for transmitting and receiving ultrasonic waves for image drawing, a vibrator 36 for irradiating therapeutic ultrasonic waves, and driving the vibrator 36 A drive circuit 16 for generating therapeutic ultrasonic waves, a temperature sensor 22 provided near the ultrasonic probe 18 for detecting temperature, and a sensor signal processing device for performing various controls based on the detected values from the temperature sensor 22 15, a water circulating device for circulating water held as an ultrasonic wave propagation medium inside the ultrasonic applicator 17, and a water circulating device 14 connected to the water circulating device 14. And a circulation hose 19 for feeding.

When the transducer 36 is driven by the drive circuit 16 and is irradiated with therapeutic ultrasonic waves, the transducer 36 generates heat and the focus f2 due to the focusing of the therapeutic ultrasonic waves.
The focal point due to the reflected wave R from the boundary surface between the body surface of the subject and the ultrasonic applicator 17 is generated near the center of the transducer 36. An ultrasonic probe 8 for drawing an ultrasonic tomographic image and observing a treatment target site is arranged near this position. For this reason, a temperature rise due to the focused ultrasonic waves occurs near the distal end of the ultrasonic probe 8.

The temperature sensor 22 detects the temperature rise and transmits it to the sensor signal processing device 15 as a temperature detection signal. When the value of the temperature detection signal exceeds a predetermined reference value, the sensor signal processing device 15 sends a control signal 21 to the drive circuit 16 based on the temperature detection signal, and
The irradiation of the therapeutic ultrasonic wave from Step 6 is stopped or the irradiation intensity is reduced. The re-irradiation can be performed when the sensor signal processor 15 continues to monitor the temperature detection signal and falls below a predetermined reference value. Further, the irradiation of the therapeutic ultrasonic wave may be restarted or strengthened by the operation of the operator.

Further, a control signal 20 is also output from the sensor signal processing device, and the control signal 20 controls the water circulation device 14. Water is held inside the ultrasonic applicator 17 as an ultrasonic wave propagation medium, and the ultrasonic waves for treatment generated by the vibrator 36 are transmitted to the treatment target site. This water is also used as a cooling means of the vibrator 36, and the heat generated in the vibrator 36 is cooled by the water. In this cooling, a desired cooling effect cannot be obtained if the water remains stagnant.
At 4, the water having a relatively low temperature is circulated. In this water circulation, a large amount of circulating water is circulated when the temperature detected by the oscillator 36 is high.

A cooling device (not shown) is provided inside the water circulating device 14 to cool water heated by the heat generated by the vibrator 36 and the like. The cooled water is again supplied to the circulation hose 19.
To the ultrasonic applicator 17 via the The water temperature is controlled by a control signal from the sensor signal processing device 15 based on a detection value from the temperature sensor 22.

The ultrasonic wave transmitting / receiving surface provided at the tip portion of the ultrasonic probe 18 is arranged at a predetermined distance from the coupling 11. This arrangement is such that, for example, when the ultrasonic applicator 17 is formed into a relatively small shape that is gripped and used by hand for use during surgery, the thickness direction is set so that it can easily enter a narrow part such as below a rib. This is also effective when the design is as thin as possible. When the ultrasonic applicator 17 is used in close contact with an exposed organ under laparotomy, it is possible to prevent the distal end portion of the ultrasonic probe 18 for drawing an ultrasonic tomographic image from coming extremely close to the coupling 11. .

In such an extreme approaching state or a state in which the tip portion of the ultrasonic probe 18 comes into contact with the inner surface of the coupling 11, the organ becomes substantially in close contact with the organ to be observed. For this reason, when the treatment target site exists in the surface layer of the organ or a relatively shallow region, it becomes difficult to satisfactorily depict the treatment target site. That is, when the field of view rendered by the ultrasonic probe 18 is a sector scan, it is inevitable that the field of view becomes narrow in a short distance portion. Further, it is difficult to satisfactorily render an image of a short-distance portion even with an ultrasonic probe of another scanning method other than the sector scanning. In an image of a short distance portion, image quality is deteriorated due to unnecessary components such as multiple reflection due to various factors.

By separating the ultrasonic probe 18 from the coupling 11 by a predetermined distance, a visual field with good image quality can be used without using a visual field portion drawn at a short distance. The site can be drawn well. In addition, the ultrasonic probe 18 is no longer located on the propagation path of the therapeutic ultrasonic wave, and irradiation of the therapeutic ultrasonic wave can be performed satisfactorily.

FIG. 3 is a schematic diagram for explaining the control of the water circulation device 14. As shown in FIG.

Irradiation of therapeutic ultrasonic waves is performed in the initial state shown in FIG. The irradiated therapeutic ultrasonic waves not only focus and focus on a target treatment target site, but also generate reflections from the surface of the subject and reflections from air bubbles, for example. If the reflected wave, which is the reflected component, is small, it is sent to the threshold determination (d) as the small reflected wave shown in (c). If the value from the temperature sensor is equal to or smaller than the temperature threshold value (f) in the threshold value determination (d), it is determined that the reflected wave is small based on the value, and the treatment ultrasonic irradiation (a) is continued.

If the reflected wave is large (b), the threshold is determined (d)
If the value from the temperature sensor is equal to or larger than the threshold value (e), control of irradiation stop / water circuit temperature decrease / water circuit circulation amount increase (g) is performed. With this control, control is performed so that a predetermined temperature is maintained with respect to a temperature rise due to irradiation of therapeutic ultrasonic waves.

This control is performed, for example, when the threshold set below the temperature threshold (f) is the same as the threshold set above the threshold (e), and when the threshold is set to 100 ° C., for example. When the threshold value is exceeded, the irradiation of the therapeutic ultrasonic wave is stopped. However, when the temperature falls below 100 ° C., the irradiation of the therapeutic ultrasonic wave is restarted. Even if the irradiation is restarted in such a state, the temperature will reach 100 ° C. again, and the irradiation will be stopped immediately, making it difficult to perform irradiation for a sufficiently long time. Therefore, the temperature threshold at which the therapeutic ultrasonic wave can be irradiated is made lower than the temperature threshold at which irradiation is stopped, and control is performed to ensure necessary continuous irradiation time.

The control is performed by controlling the temperature by changing the intensity of the irradiation of the therapeutic ultrasonic wave continuously or stepwise.
Alternatively, a configuration in which only the control of the start and stop of the irradiation with respect to the threshold value may be used, and good irradiation control can be performed by combining the two controls.

FIG. 4 is a schematic view of an applicator for an ultrasonic therapy apparatus according to the present invention.

(A) is a bird's-eye view of the ultrasonic applicator 23, (b) is a bird's-eye view, and (c) is a side view. According to the first embodiment or the second embodiment of the present invention, even if the ultrasonic applicator 23 is downsized, effective measures are taken against a rise in temperature accompanying irradiation of therapeutic ultrasonic waves. Therefore, stable and reliable ultrasonic irradiation can be performed. In particular, since a countermeasure is effectively taken against a rise in temperature, a small ultrasonic applicator 23 as shown in FIG. 4 can be provided. Such a small ultrasonic applicator eliminates the need for a configuration such as an operation arm that conventionally moves and operates the ultrasonic applicator. Can be irradiated.

The ultrasonic applicator 23 has an irradiation start switch 27 for irradiating therapeutic ultrasonic waves to improve operability, and an irradiation stop switch 26 for stopping irradiation of therapeutic ultrasonic waves. A probe up / down operation button 24 for raising / lowering an ultrasonic probe for obtaining an ultrasonic tomographic image, a probe rotation lever 25 for rotating the ultrasonic probe, and a connection cable for transmitting a drive signal and transferring water. 30 and a coupling thickness adjustment button 28 for controlling the amount of water held inside the coupling to control the thickness of the coupling.

Further, a foot-operated foot switch (not shown) is provided in the ultrasonic treatment apparatus as auxiliary irradiation control means. The operator performs various operations such as the irradiation start switch 27 and the irradiation stop switch 26 while holding the ultrasonic applicator 23. By combining a foot switch in this operation, for example, it is possible to prevent an erroneous operation by making it impossible to operate the above various operation switches unless the foot switch is depressed. Further, by providing the operation function of various operation switches to the foot switch, the function operation can be performed even when the hand cannot be freed by another operation. Of course, depending on the design intent, the footswitch may have other functions or any function of the operator.

FIG. 5 is a schematic view for explaining another shape of the ultrasonic applicator shown in FIG.

(A) shows a bird's-eye view, and (b) shows a state where the operator is holding the hand 35. An irradiation start switch 31 for starting irradiation of therapeutic ultrasonic waves, an irradiation stop switch 32 for similarly stopping irradiation of therapeutic ultrasonic waves, and a therapeutic ultrasonic wave that is in close contact with the body surface of the subject. A coupling 33 for good propagation, a connection cable 34 in which a wiring for various driving and control and a hose for circulating water are housed, and a grip portion 36 for the operator to grip by hand. Equipped.

As shown in (b), the operator can hold and operate the ultrasonic applicator with one hand. The grip portion 36 stands up while drawing an arc in a substantially bar shape, and preferably the operator can insert the hand 35 into the inside of the formed arc so that good grip can be performed. In this gripped state, the operation of the irradiation start switch 31 and the irradiation stop switch 32 can be freely performed by the operator's finger.

The embodiments described above are described for facilitating the understanding of the present invention, and are not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.
