Abstract

PURPOSE:To enhance the adhesivity to a living body and to improve a treatment effect by providing the treatment device with an applicator mounted with a porous material and a second porous material in which this applicator is arranged and forming this second porous material to a bag body which consists of a soft and thin film and is opened in the upper part. CONSTITUTION:This treatment device has the porous material (second porous material) which is the bag body consisting of the thin and soft material, such as silicone rubber sheet, when the device is applied to an ultrasonic thermotherapic device (hyperthermia). The upper part of the porous material is supported on a frame body 9 in the form of opening the upper part and deaerated water 7 is housed therein. The ultrasonic applicator 1 integrally holding the porous material 2 supported in a supporting arm 12 is dipped and positioned in the deaerated water 7 in such porous material. Ultrasonic waves are thereafter generated by driving the ultrasonic applicator 1 to make the thermotherapy of the desired treating section in the living body 4. Since the second porous material is held in tight contact with the surface of the living body 4, the thermotherapy is effectively executed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a therapeutic device for irradiating an ultrasonic wave or a microwave generated outside the body to a treatment target portion in a subject (living body) to perform heat treatment or crush treatment on the target portion. In particular, it relates to a bolus applied to the body surface of a subject.

2. Description of the Related Art When ultrasonic waves (microwaves) are applied to a living body, when air is present between an applicator that generates ultrasonic waves (microwaves) outside the body and the living body, the acoustic impedance ρ (dielectric constant ε) of both is applied. ) Is so different that reflection occurs at the interface between the two (air and living body) and ultrasonic waves (microwave)
However, there is a problem in that the light does not enter the living body, or there is a portion called a hot spot where the temperature becomes too high. The reflectance at the boundary surface is the acoustic impedance difference between the living body (muscle) and air of 1.7.
If it is 0,0.00042 [kg / (m 2 · sec)], it will be 99.9%.

Therefore, as shown in FIG. 4, the ultrasonic wave generated by the applicator (in order to guide microwaves into the subject without loss, the applicator 1 has a matching acoustic characteristic similar to that of a living body, as shown in FIG. A good liquid (usually degassed water,
A bag-shaped bolus 2 made of a material such as silicon for holding deionized water) is provided. When the bolus 2 for holding the matching liquid is interposed between the applicator 1 and the living body in this way, the reflectance at the interface between the bolus 2 and the living body at this time is 1.47 acoustic acoustic impedance.
When [kg / (m 2 · sec)] is set to 6.5%, the consistency is greatly improved compared to the case of air.

Since the surface of a living body (body surface) often has a convex shape, and also has many fine uneven surfaces,
As shown in FIG. 5, it is impossible to completely bring the bolus 2 thus inflated into close contact with the surface of the living body, and a fine air layer 5 is formed.

When the air layer 5 is generated in this way, the heating region becomes narrow, and the ultrasonic waves (microwaves) generated by the applicator 1 cannot be irradiated into the living body, and the living body is in close contact with the living body. The ultrasonic waves radiated on the bolus 2 that has not been reflected repeatedly at the air layer as shown by the arrow.
Eventually, the area where the living body and the bolus are in close contact is irradiated, and hot spots tend to occur on the surface.

In the embodiment of FIG. 1, the deaerated water 7 is not circulated in the bolus 6, but the applicator 1 of the main body is put into the deaerated water 7 so that the bolus 2 attached to the applicator 1 indirectly Cooling. Further, since it is in the shape of a bag with the upper part open, it does not receive a large outward pressure, so the strength of the material of the bolus 6 should be strong enough to contain the degassed water 7, and is so large. Does not require strength.

Since the bag constituting the bolus 6 is sufficiently thin and the upper side is open, the shape can be freely changed by the weight of the degassed water 7, and the convex surface of the living body 4 and fine irregularities Even if it exists, it naturally adheres. At this time, if a transparent material is used for the bolus 6, the presence or absence of air between the bolus 6 and the living body 4 can be observed. Further, since the bolus 6 automatically follows the vertical movement and body movement caused by the patient's breathing, no air layer is generated.

After the bolus 6 is positioned, the ultrasonic applicator 1 for integrally holding the bolus 2 supported by the support arm 12 of the ultrasonic thermotherapy device body (not shown) is removed from the second bolus 6. It is immersed in air / water 7 for positioning (FIG. 2 shows this positioned state), and thereafter, the ultrasonic applicator 1 is driven to generate ultrasonic waves to perform thermal treatment of the target treatment site in the living body 4. To do.

Since the second bolus 6 is larger than the size of the applicator 1, all the irradiated ultrasonic waves enter the living body and can be heated efficiently, and a desired temperature distribution can be obtained. It will be. Further, by changing the distance between the applicator 1 and the living body 4 in the second bolus 6, the focusing point of ultrasonic waves in the living body also changes, and the heating area can be easily changed according to the depth of the treatment site. It is possible to change.

Next, the case where the treatment is performed from the side of the patient is shown in FIG.
Will be described. When the bolus 6 is brought into close contact with the side of the living body, the weight of the bolus 6 alone cannot be used for complete contact, so the frame 9 is bent in advance so as to fit the curved surface of the living body 4. In this state, when the curved surface of the frame body 9 is brought into contact with the side portion of the living body 4 so as to be in contact with the living body 4, the deaerated water 7
The shape of the side surface of the bolus 6 is freely changed by the fluidity of, and the bolus 6 closely adheres to the side surface of the living body 4 without generating an air layer.

In the figure, if the living body 4 is tilted to the right, the weight of the degassed water 7 is also added, so that the close contact from the side becomes better. After positioning the bolus 6, change the ultrasonic applicator 1 from the direction shown in FIG.
Then, the ultrasonic wave applicator 1 is driven to perform the thermal treatment.

In this case, it is possible to provide another unit for circulating the degassed water in the second bolus while degassing and cooling. Since the upper portion of the bolus 6 is open even when the circulation is performed, the bolus does not expand and the pressure does not increase unlike the conventional example.

According to the present invention, the second bolus of the open type is provided separately from the bolus attached to the applicator so as to contact the living body surface in which the applicator is disposed. The shape of the bolus changes freely along the concavo-convex shape of the surface of the living body and adheres to the surface of the living body without creating an air layer, so that ultrasonic waves (microwaves) can be efficiently incident on the living body. When the invention is applied to an ultrasonic treatment apparatus, a desired heating distribution can be obtained without causing hot spots. In addition, the bolus can follow up and down movements caused by the patient's breathing, and since it is not necessary to press the applicator, the burden on the patient is small,
The therapeutic effect can be significantly improved.
