Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a shock wave treatment device that destroys and treats objects to be treated, such as cancer cells, stones, etc., inside a subject by using the focused energy of shock waves. Regarding.

(Prior Art) There is a conventional ultrasonic treatment device disclosed in Japanese Patent Application Laid-Open No. 62-049843. A sectional view of the ultrasonic applicator constituting this ultrasonic treatment device is shown in FIG.

The ultrasonic applicator 1 shown in the figure includes a concave transducer 2 having a curvature of 10 cm in diameter and a handling hole of a predetermined shape in the center, and a backing material 3 uniformly bonded to the back surface of the concave transducer 2. It consists of

The imaging ultrasonic probe 4 is a sector probe that is fixed in the handling hole and has a transducer array 4a formed by arranging thin transducers facing the curved surface of the concave transducer 2.

5 in the figure is an acoustic coupler, which is filled with water,
It consists of a bag 6 made of a thin membrane having an acoustic impedance approximately equal to that of water.

On the other hand, an ultrasonic treatment device equipped with an ultrasonic applicator 7 as shown in FIG. 6 is also used.

That is, the ultrasonic applicator 7 shown in the same figure is
A concave transducer 9 similar to the concave transducer 2 shown in FIG. The device includes a water tank 10 whose interior is filled with water, and a mechanical probe 11 provided within the water tank 10.

Note that 12 in the figure indicates the focused state of the ultrasonic waves generated by the concave transducer 9.

Therefore, in the ultrasonic applicator 1 shown in FIG. 5, the ultrasonic wave transmitting/receiving surface (ultrasonic array) 4a of the imaging ultrasonic probe 4 is the same curved surface as the ultrasonic wave transmitting/receiving surface of the concave transducer 2, or is set back from the same curved surface. It is placed in the specified position.

In the ultrasonic applicator 1 having such a configuration, first, the ultrasonic waves transmitted and received by the imaging ultrasonic probe 4 are transmitted through water filled inside the acoustic coupler 5 and further through a thin membrane that contacts the subject. Therefore, scattering, attenuation, etc. cannot be avoided. Therefore, the display image displayed on the display section (not shown) is affected by noise, making it difficult to recognize the object to be treated.

Further, when the object to be treated is displayed on the display section, the display position of the object to be treated is displayed below both sides of the object, so there is a problem that it is difficult to confirm the object to be treated.

On the other hand, in addition to the problems shown in FIG. 5, the imaging ultrasound probe 11 shown in FIG. 6 has drawbacks due to being a mechanical probe, namely, a decrease in the quality of displayed images.
T! There were problems such as an increase in the size of the structural parts and a weakness in photographing. Furthermore, the ultrasonic applicator 7 shown in the figure has a drawback in that it is difficult to handle because it is fixed to the bed 8. Therefore, the present applicant has previously proposed a shock wave therapy device equipped with a shock wave applicator that transmits shock waves toward a subject, the shock wave applicator comprising a shock wave transducer that forms a focal point of shock waves within the subject; A water tank provided on the shock wave transmitting surface of the shock wave transducer, and a water tank disposed within the shock wave transmitting region from the shock wave transmitting surface of the shock wave transducer to the focal point, and with the ultrasonic wave transmitting and receiving surface in contact with the surface of the subject. We have proposed a shock wave therapy device characterized by comprising an ultrasonic transducer that forms a sound field region including a focal point and collects tomographic image data of the subject (
Patent application No. 62-290158>.

(Problem to be Solved by the Invention) The position of the object to be treated from the body surface differs between adults and children, and depending on the organ in which the object is located.

Furthermore, the attenuation of ultrasound waves differs depending on the constitution of the patient. Therefore, it is necessary to change the imaging ultrasound probe to one with different characteristics depending on the position from the body surface of the object to be treated and the patient's constitution. It wasn't taken into account.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a shock wave treatment device in which several imaging ultrasonic probes with different depths of transmitting and receiving image regions can be easily exchanged, and in which the object to be treated within the subject can be easily recognized. is.

[Configuration of the Invention] (Means for Solving the Problems) In order to achieve the above object, the configuration of the present invention provides a shock wave therapy device including a shock wave applicator that transmits shock waves toward a subject. The shock wave applicator includes a shock wave transducer having an opening in the center and forming a shock wave convergence point within the subject, and a storage cylinder arranged on a line connecting the center of the opening of the shock wave transducer and the shock wave convergence point. and an imaging ultrasonic probe that is removably housed in the storage tube and collects tomographic image data of a region including the focal point of the shock wave.

(Function) When a pulse signal is sent to the shock wave transducer, an ultrasonic pulse with strong energy is directed from the transducer to the focal point of the shock wave and treats the object placed at this focal point.

On the other hand, when a pulse signal is transmitted to the imaging ultrasonic probe, this probe transmits and receives ultrasonic waves in a region including the focal point of the shock wave, and a tomographic image of this region is displayed on the display means. When treating the object to be treated, the ultrasound transmitting and receiving surface of the imaging ultrasound probe is brought into contact with the surface of the object,
The target area to be treated is shown in a tomographic image. In order to focus the shock wave on the imaged object to be treated, the shock wave transducer is moved relative to the imaging ultrasound probe in the axial direction of the probe. - On the other hand, the object to be treated can be clearly imaged in the tomographic image by selecting an imaging ultrasonic probe having a penetration depth corresponding to the depth from the surface of the subject to the object to be treated. For this reason, the present invention has a structure in which the imaging ultrasound probe can be easily replaced by simply putting it in and taking it out of the storage tube. Further, by providing an acoustic coupler under the shock wave transmission surface of the shock wave transducer, shock waves can be efficiently transmitted. If the acoustic coupler contains a liquid and has a flexible side surface, when the shock wave transducer is moved in the axial direction of the imaging ultrasound probe with the bottom of the acoustic coupler in contact with the surface of the object, Since the sides of the acoustic coupler are flexible, the position of the transducer can be easily adjusted. Furthermore, when the transducer is moved, the elastic ring that maintains contact with the outer periphery of the storage tube prevents liquid from leaking inside the acoustic coupler. By lightly locking the locking tool to the locked portion of the imaging ultrasonic probe, the probe 7 can be rotated around the axis of the probe, allowing a wide search for the object to be treated. By strongly locking the locking tool to the locked portion, the probe can be fixed.

By the way, the position of the focal point is determined geometrically once the relative position of the shock wave transducer with respect to the imaging ultrasound probe is determined. Therefore, the display means displays a marker indicating the position of the focal point in the tomographic image. The operator looks at the displayed tomogram and the marker, and operates the shock wave transducer to align the marker with the object to be treated in the tomographic image in order to align the marker, which is the focal point, with the object to be treated in the tomographic image. Then, a shock wave is transmitted to treat the object to be treated.

In this manner, the positional relationship between the object to be treated and the focal point of the shock wave can be easily determined, and the focal point can be aligned with the object to be treated, so that the object to be treated can be treated accurately.

(Example) An example of the present invention will be described below with reference to the drawings. In this embodiment, an example in which an ultrasonic wave generated by a vibrator is used as a shock wave will be explained.

Next, the shock wave applicator 17 will be described in detail with reference to FIGS. 1 to 3.

First, in FIG. 1(a), the shock wave applicator 17 is
A focal point 41 of shock waves (e.g. ultrasonic pulses of high energy) for treating the object to be treated, e.g. kidney stones, in the subject 32
The shock wave transducer 1-15 forming the shock wave transducer 1-a, the liquid bag 33 provided on the shock wave transmission surface 15a side of the shock wave transducer 15, and the center of the central opening A of the shock wave transducer 15 and the focusing point 41a are connected.

It is configured to include an imaging ultrasonic probe 16 that collects tomographic image data of the subject 32.

The shock wave transuser 15 includes a concave vibrator having a constant curvature.

The details of the opening A of the shock wave transducer 15 are shown in FIG.
) and is formed into a cylindrical stainless steel storage cylinder 54. A concave connecting member 43 having an opening 83 a with an inner diameter slightly larger than the outer diameter of the storage tube 54 is provided around the storage tube 54 .

A vertical movement driving section 36, which is a vertical movement means for vertically moving the shock wave transducer 15, is provided between the connecting member 43 and the storage tube 54.

The vertical movement means 36 of this transducer 15 moves arbitrarily in the direction of arrow E based on a control signal from the position controller 30 (see FIG. 4) described above.

It is equipped with a driving force transmission means that can be stopped and its driving source. In this embodiment, the driving force transmission means includes a rack 36a fixed to the side surface of the storage tube 54, and a pinion gear 36b that meshes with the rack 36a. This pinion gear 36b is driven by a motor 36G as a driving source.
attached to the drive shaft. Further, the motor 36
G is attached to the connecting member 43 by a motor support fitting 36d.

Next, as shown in FIG. 1(C), a detection unit for detecting the vertical position of the shock wave transducer 15
4, and an optical photo sensor 90b that detects the black scales 90a at equal intervals.
The photosensor 90b includes a support fitting 9.
1 to the connecting member 43.

The vertical movement means 36 of the shock wave transducer 15 configured as described above receives a position detection signal from the photosensor 90 at the position controllers 1 to 30, and controls the rotation angle of the motor 36C by the controller 30. The vertical position of the transducer 15 with respect to the imaging ultrasound probe 16 is adjusted. Further, if the motor 36C is not energized, the vertical position of the transducer 15 can be maintained by the holding force of the motor 36G.

The liquid bag 33 is filled with water as a shock wave transmission liquid, and has a substantially cylindrical shape with a bottom or a truncated cone shape having an outer diameter approximately equal to the outer diameter of the shock wave transducer 15. A bellows 33a that can expand and contract in the direction of arrow E or within a predetermined angle in that direction is formed on its side, and the bottom part 37 is a thin rubber film having an acoustic impedance approximately equal to that of water. The details of the connecting portion B between the bottom portion 37 and the bellows 33a are shown in FIG. 1(d), and the details of the connecting portion C between the bottom portion 37 and the storage cylinder 54 are shown in FIG. 1(e). The outer periphery of the bottom portion 37 has an outer reinforcing ring 37a, and the ring 37a connects the outer reinforcing ring 37a and the lower end of the bellows 33a to a ring-shaped receiver with a metal fitting 61. It is sandwiched between a ring-shaped presser metal fitting 62 divided into several large-diameter parts, and fixed with a fixing bolt 63. Next, the inner peripheral edge of the bottom portion 37 has an inner reinforcing ring 37b, and this inner reinforcing ring 37b is
A ring-shaped receiver fixed to the storage n54 is sandwiched between a metal fitting 71 and a ring-shaped holding fitting 72 divided into several parts, and is fixed with a fixing bolt 73. Further, in order to cover the tip of the imaging ultrasonic probe 16 with the inner cylinder part 37c, a reinforcing ring 75 made of rubber harder than the bottom part 37 is provided around the inner cylinder part 37c, and a band 74 is provided around the inner cylinder part 37c. is fixed. In order to press the inner cylindrical portion 37c against the reinforcing ring 75, the imaging ultrasonic probe 16 is used.
A resilient ring-shaped sponge 7b is inserted between the inner cylinder portion 37G and the inner cylinder portion 37G.

Since the bottom part 37 is a thin film, there is a possibility that it will be torn, and even if it is torn, the bottom part 37 can be easily replaced because it is attached as described above. When replacing the outer reinforcing ring 37a, remove the presser metal fitting 62 that fixes the outer reinforcing ring 37a, lower the outer reinforcing ring 37a, drain the water inside, and remove the presser metal fitting 72 that fixes the inner reinforcing ring 37b and the inner side. This can be done by removing the band 74 that fixes the cylindrical portion 37c.

Next, the structure of the central opening A of the shock wave transducer 15 will be explained with reference to the detailed diagram shown in FIG. 1(f).

The connecting member 43 has a groove 43a for the O-ring 52 on the inner periphery.
and a support tube 43b, and the presser metal fitting 51 has a collar 51.
The support cylinders 43b and 5 have a support cylinder 51b and a support cylinder 51b.
1b, the connecting member 43 is connected to the imaging ultrasonic probe 11.
It functions to support so that it does not tilt with respect to the axial direction of 6. The O-ring 52 is made of rubber, is sandwiched between the collar 51a and the groove 438, and is brought into contact with the outer periphery of the storage tube 54 due to the elasticity of the O-ring 52. Thereby, even if the shock wave transducer 15 is moved up and down, the water in the liquid bag 33 will not leak.

As for how to use this shock wave treatment device, when the ultrasound probe 16 for imaging is held vertically and the ultrasonic wave transmitting/receiving surface 16a is brought into contact with the subject surface 32S, if the target treatment object 39 is shifted from directly below the transmitting/receiving surface 16a. The imaging ultrasonic probe 16 and the shock wave transducer 15 are used at an angle. This tilt machine purchase will be explained with reference to FIG. 1(a).

Vertical bearings 85 are fixed to opposing positions on the outer periphery of the shock wave transducer 15, and the bearings 85 move up and down on the vertical movement rail 84. A stopper 84affi is provided at the lower end of the vertically movable rail 84 to prevent it from coming off. The vertically movable rail 84 is connected to the storage cylinder 54 by a connector 83 in parallel to the central axis of the storage cylinder 54. An inclined bearing 82 is fixed to the upper part of this connector 83, and this bearing 82 moves on an inclined rail 81. This inclined rail 81 is suspended by hanging frames 80 at both ends, and has a structure in which the entire shock wave applicator 17 can be suspended and moved. The inclined rail 81 has an arc shape centered on the center of the ultrasonic wave transmitting/receiving surface 16a. Therefore, the shock wave applicator 17 can be tilted manually while maintaining the relative positions of the shock wave transducer 15 and the imaging ultrasound probe 16 around the focal point 41a. Furthermore, if it is desired to change the inclined surface, this can be done by rotating the hanging frame 80.

Since the imaging ultrasound probe 16 has a constant ultrasound penetration depth, the depth of the wave transmission/reception image area 42 is determined. On the other hand, adults and dwarfs differ in the depth of stones from the body surface, even if they are in the same organ. So, for adults,
A low frequency (3.75 Hz) imaging ultrasound probe 160 is used to detect stones located deep from the body surface, and in the case of a dwarf, a high frequency (5) 1tlZ) imaging ultrasound probe 161 is used. Use it to imitate stones located shallowly from the body surface. Since the probe 161 has a high frequency, a high quality image can be obtained. Furthermore, the depth of a stone from the body surface varies depending on the location of the stone. For example, the imaging ultrasound probes 16, 16 have different frequencies depending on stones with different depths, such as stones in the bladder and stones in the gallbladder.
It is necessary to select 0,161. Furthermore, the patient's constitution (
It is better to select the probe 16 depending on whether the body is fat or muscular. It is better to use a low-frequency probe 160 with a deep penetration depth for a fat and fat person, and use a high-frequency probe 161 with a shallow penetration depth but with a clear image for a thin and muscular person.

Therefore, the imaging ultrasonic probe 16
It is necessary to change the characteristics to those having different characteristics depending on the depth from the subject surface 32S of No. 9.

Therefore, in this embodiment, the imaging ultrasound probe 1
6 is provided with a storage tube 54 that removably stores the storage device 6. Further, in order to facilitate finding the object to be treated 39, the imaging ultrasonic probe 16 is structured to be rotatable about the central axis of the probe. These structures are shown in FIG. 1(b). The gap between the inner diameter of the storage tube 54 and the outer diameter of the imaging ultrasound probe 16 is 0.1 to 1 mm.
Moderately small. Therefore, the probe 16 can be easily inserted into the storage tube 54 without play.

A guide groove 16G serving as a stopper is provided in the circumferential direction of the circumferential surface of the probe 16 near the top thereof. The probe 116 is placed in a position where the ultrasonic wave transmitting/receiving surface 16a can be brought into contact with the subject.
When inserted, the locking screw 16b, which is a locking tool, is tightened, and the screw 16b is passed through the hole 54a provided in the storage tube 54 and pressed against the groove 16c.

If the locking screw 16b is inserted shallowly into the guide groove 16G, the imaging ultrasound probe 16 can be rotated about the central axis of the probe 16, and the locking screw 16b can be inserted into the guide groove 16G.
If the probe 16 is strongly pressed against the bottom of the probe 0, the probe 16 can be fixed, and will not shift due to imaging even if the shock wave transducer 15 is operated. Further, this locking portion may be made of other MPS construction as shown in FIG.

The imaging ultrasonic probe 162 has a collar 162a at the top instead of the groove 16G, and when the probe 162 is inserted, the stopper 162a hits the upper end surface of the storage tube 54, and the vertical positioning is controlled. The probe 16 can be tightened in the same way by tightening the locking screw '16b.
2 can be fixed.

The overall operation and effects of the shock wave treatment device configured as described above will be explained mainly assuming that a kidney stone 39 in the kidney shown at 38 in FIG. 1(a) is treated.

In advance, an imaging ultrasonic probe 16 corresponding to the position from the body surface of the object to be treated is selected, inserted into the storage tube 54, and fixed with the locking screw 16b.

Next, the liquid bag 3 provided in the shock wave applicator 17
3 is placed on the upper surface 323 of the kidney 38 of the subject 32.

Then, the transmitter/receiver circuit 19, signal processing circuit 20, and signal conversion system 21 are controlled to drive the imaging ultrasound probe 16 to display a tomographic image of the subject 32 on the screen of the display means 27. In this case, the imaging ultrasound probe 16
Since the ultrasonic wave transmitting/receiving surface 16a directly contacts the subject surface 32S, it is possible to eliminate the influence of the bottom of the liquid bag, water, etc. and obtain a clear tomographic image. Therefore, it becomes easy to grasp and recognize the object to be treated.

Next, the imaging ultrasonic probe 16 is operated in order to depict the object to be treated on the previous tomographic image.

That is, the probe 16 can be tilted by moving the tilt bearing 82 onto the tilt rail 81, or the locking screw 16b can be tilted.
is slightly loosened and the probe 16 is rotated around the wire so that the object to be treated can be clearly imaged on the tomographic image.

On the screen of the display means 27 on which this tomographic image is displayed, a signal from a detection unit 90 that detects the vertical position of the focal point 41a of the shock wave transducer 15 with respect to the imaging ultrasound probe 16 is transmitted to the CPU 22 and the signal converter. System 2
1 as a marker 26 in real time.

Here, this marker 26, that is, the focal point 41 is located on the object 3 to be treated.
9, operate the position controller 30 to match
The shock wave transuser 15 is moved in the vertical direction.

In this case, the ultrasonic wave transmitting/receiving surface 16a of the imaging ultrasonic probe 116 is connected to the opening A of the shock wave transducer 15.
Since the center of the object is connected to the focal point 41a and arranged on the S-line, the display position of the object to be treated can be positioned at the center of the screen. Therefore, it becomes easy to confirm the object to be treated. Further, since the relative positional relationship between the shock wave transducer 15 and the imaging ultrasonic probe 16 can be adjusted, treatment can be further facilitated.

Next, the operator operates the first switch of the pulse generation switch 29 to control the CPU 22. A control signal is transmitted to the pulser 18 via the controller 23.

This allows the balsa 18 to move from the shock wave transducer 15.
A pulse signal is transmitted to the transducer 15, and the transducer 15 transmits an ultrasonic pulse (shock wave) of intense energy toward the kidney stone 39 located at a position corresponding to the position of the focal point marker 26.

This ultrasound pulse is at the location of kidney stone 39! ! It becomes a shock wave and destroys kidney stones.

By repeating the generation of such ultrasonic pulses as many times as necessary, the entire kidney stone 39 can be destroyed and treated.

Although one embodiment has been described above, the present invention is not limited to this, and various modifications can be made without changing the gist thereof.

For example, in the above embodiment, the therapeutic ultrasound is generated by a vibrator, but an electromagnetic induction type shock wave generation source may also be used.

Further, as shown in FIG. 3, an O-ring 5 is provided on the front surface of the ultrasonic wave transmitting/receiving surface 16a by extending rubber made of the same material as the bottom portion 37, and abutting the imaging ultrasonic probe 16 at the lower end of the storage cylinder 54.
4d may be provided. When the ultrasonic wave transmitting/receiving surface 16a of the probe 16 does not contact the subject surface 32S, the bottom portion 37
Since water having an acoustic impedance close to that of the human body is present between the probe 16 and the probe 16, ultrasonic waves are efficiently transmitted and a high-quality tomographic image 14 is obtained.

The detection unit 90 may include a variable resistance potentiometer on the pinion gear 36b side instead of the black scale 90a provided on the side surface of the storage cylinder 54 and the photosensor 90b.

Furthermore, in the above embodiment, the shock wave transducer 15 is moved up and down by the vertical movement drive unit 36, but instead of moving this transducer 15 up and down, the imaging ultrasound probe 16 may be moved up and down by the vertical movement means. good.
