  However, in the conventional technique, the ratio of the spring mechanism to the entire apparatus is large, and the apparatus configuration is relatively large. Therefore, there is a problem that a feeling of pressure is given to the patient and the feeling of use is poor.

  The present invention has been made in consideration of such circumstances, and it is an object of the present invention to reduce the size and obtain a good feeling of use.

In order to achieve the above object, the present invention employs the following means.
That is, the ultrasonic treatment device according to the present invention is provided with a vibrator that irradiates an affected part in a wounded part of a body with ultrasonic waves, a holding part that holds the vibrator, and the holding part. A pair of band portions extending in a direction away from each other, and the pair of band portions provided in the pair of band portions, with the pair of band portions wound around the wound site in an annular shape, the relative displacement of the pair of band portions is And a pair of band portions made of an elastic body.
According to this configuration, since the pair of band portions is made of an elastic body, when the pair of band portions are elastically stretched and deformed and wound around the wound site in an annular shape, the elastic restoring force of the pair of band portions causes the vibrator Is urged toward the radially inward side (radial center side) and is in close contact with the wound site. Thereby, even if the spring mechanism is omitted, the close contact between the diseased part and the vibrator can be ensured, but the device configuration is simpler than the case where the spring mechanism is provided. And a good feeling of use can be obtained.

Further, the pair of band portions are integral with the holding portion.
According to this configuration, since the pair of band portions are integrated with the holding portion, the device configuration is further simplified, and further downsizing can be achieved.

Further, the pair of band portions is formed of silicon rubber.
According to this configuration, since the pair of band portions is formed of silicon rubber, it is possible to configure a band portion that is superior in heat resistance, water resistance, and chemical resistance compared to other elastic materials.

In addition, the restraining portion is provided in a first hook-and-loop fastener provided in one band portion of the pair of band portions, and in the other band portion of the pair of band portions, and the pair of band portions is A second hook-and-loop fastener that faces the first hook-and-loop fastener in a state of being wound around the wound site in an annular shape, and at least one of the first hook-and-loop fastener and the second hook-and-loop fastener is the pair In the extending direction of the band portion, a plurality of continuous portions are provided with a gap.
According to this configuration, since at least one of the first surface fastener and the second surface fastener is continuously provided with a gap in the extending direction of the pair of band portions, The portion of the band corresponding to the gap is elastically stretched and deformed without being affected by the surface fastener. Thereby, the favorable elasticity of a pair of band part is ensured, and a wounded part and a vibrator | oscillator can be made to closely_contact | adhere.

In addition, the holding portion is formed in a cylindrical shape so that the vibrator is fitted into a cylindrical hole, and the ultrasonic wave is held in a state where the irradiation direction of the ultrasonic wave is directed to the cylindrical axis direction of the cylindrical hole. The pair of band portions extend from the outer peripheral surface to one end portion on the irradiation direction side in the tube axis direction, and the other end portion in the tube axis direction of the tube wall of the holding portion. A pair of peripheral walls facing each other in the extending direction of the pair of bands is formed on the side, and a locking claw for restricting displacement of the vibrator in the cylindrical axis direction is formed on each of the pair of peripheral walls. It protrudes from the inner peripheral surface.
According to this configuration, the pair of band portions extend from the outer peripheral surface to one end portion of the cylindrical wall, and the pair of peripheral walls facing each other is formed on the other end portion, and the pair of peripheral walls has a vibrator. Since the locking claws that restrict the displacement of the tube in the cylinder axis direction protrude from the inner peripheral surface, the pair of band portions are elastically extended and deformed, so that the one end portions of the tube wall are pulled away from each other. Then, the locking claw is displaced toward the ultrasonic irradiation direction and the radial center. As a result, the vibrator can be biased toward the wounded part, and the wounded part and the vibrator can be satisfactorily adhered to each other.

In addition, an ultrasonic treatment system according to the present invention is provided between any of the above ultrasonic therapeutic devices and the affected part and the vibrator, and the ultrasonic wave irradiated from the vibrator is applied to the affected part.

As shown in FIGS. 2 and 3, the vibrator fixture 30 includes a holding portion 40, a pair of band portions 50 </ b> A and 50 </ b> B, and a restraining portion 60.

  As shown in FIG. 1, the holding portion 40 is formed in a cylindrical shape, and the vibrator 20 is fitted into a cylindrical hole 40 a defined in a cylindrical wall 41 extending in the circumferential direction. More specifically, the holding portion 40 has the outer peripheral surface of the vibrator 20 and the cylinder wall 41 in a state where the irradiation direction of the ultrasonic wave is directed in the cylinder axis direction of the cylinder hole 40a (the direction in which the cylinder axis P extends). The vibrator 20 is held by friction acting between the inner peripheral surface of the vibrator 20 and the inner peripheral surface.

As shown in FIG. 3, a pair of band portions 50A and 50B extends from the outer peripheral surface 41b at one end portion (in the ultrasonic wave irradiation direction) 41a in the tube axis direction of the tube wall 41.
On the other hand, a pair of peripheral walls 42A and 42B facing each other in the extending direction of the pair of band portions 50A and 50B are formed on the cylindrical wall 41 on the other end portion 41c side in the tube axis direction.

  As shown in FIGS. 2 and 3, locking claws 43 </ b> A and 43 </ b> B project from the respective inner peripheral surfaces 42 a and 42 a toward the cylinder axis P in a plan view arc shape on the pair of peripheral walls 42 </ b> A and 42 </ b> B. These locking claws 43A and 43B regulate displacement of the vibrator 20 in the cylinder axis direction (the direction opposite to the ultrasonic wave irradiation direction).

As shown in FIGS. 2 and 3, the pair of band portions 50 </ b> A and 50 </ b> B extends from the outer peripheral surface 41 b of the holding portion 40 as described above, and extends from the holding portion 40 in directions away from each other. ing. The pair of band portions 50A and 50B are each formed in a band shape, and are integrally formed with the holding portion 40 with silicon rubber.
This silicon rubber is blue and transparent.

As shown in FIG. 2, the band portion 50A has a width dimension shorter than that of the peripheral wall 42A, and the extending dimension is about three times that of the band portion 50B.
The band portion 50B has a width dimension shorter than that of the peripheral wall 42B, and is formed to have substantially the same length as the band portion 50A.

The restraint portion 60 includes a female hook-and-loop fastener (first hook-and-loop fastener) 60A and a hook-and-loop fastener male (second hook-and-loop fastener) 60B.
The hook-and-loop female die 60A is a strip-like member in which a large number of loop-shaped raised hairs protrude, and as shown in FIGS. 2 and 3, the band portion 50A is linearly extended and positioned on the ultrasonic irradiation direction side. It is disposed on the back surface 60a. Three surface fastener female dies 60A are arranged with a gap C from the end. The two gaps C are substantially the same, and the dimension in the extending direction of the band portion 50A is smaller than that of the surface fastener female die 60A.

  The hook-and-loop fastener male mold 60B is a strip-shaped member in which a large number of hook-shaped brushes protrude, and as shown in FIGS. 2 and 3, the band portion 50B extends linearly with respect to the ultrasonic irradiation direction. One is disposed on the upper surface 60b extending in the reverse direction. This surface fastener male mold 60B can be engaged with three surface fastener female molds 60A.

  With such a configuration, the restraining portion 60 can restrain the relative displacement of the pair of band portions 50A and 50B in a state in which the pair of band portions 50A and 50B are wound around the wound site (hand, foot, etc.) in an annular shape. is there. More specifically, the band 50B is positioned on the inner side and the band 50A is positioned on the outer side, as viewed from the wound site, and one of the three hook-and-loop fastener male molds 60B is opposed to the hook-and-loop female female mold 60A. By engaging with the surface fastener female die 60A, the relative displacement of the pair of band portions 50A and 50B is restricted.

  The ultrasonic therapy device 10 having the above configuration is assembled by inserting the lead wire 21 of the transducer 20 into the cylindrical hole 40a of the holding portion 40 and then fitting the transducer 20 into the cylindrical hole 40a.

4 is a schematic configuration diagram of a gel pad sheet 101 to which a plurality of gel pads 100 are affixed. FIG. 4 (a) is an overall perspective view, and FIG. 4 (b) is a cross-sectional view taken along the line II-II in FIG. FIG.
The gel pad 100 has a circular shape with a slightly larger diameter than that of the vibrator 20, and is obtained by impregnating a polymer material such as a urethane resin with moisture. The gel pad 100 is affixed to a wound site and conducts the ultrasonic wave emitted from the vibrator 20 to the affected area.

  As shown in FIG. 4 (a), such a gel pad 100 is affixed in a plurality of rows on one surface of a rectangular film sheet 102 made of synthetic resin, and as shown in FIG. A circular film sheet 103 formed with substantially the same diameter as the gel pad 100 is affixed to a front surface 100b that is in a relationship of front and back with the back surface 100a in contact with the sheet 102.

Then, the effect | action of the ultrasonic therapy system 1 which consists of an above-described structure is demonstrated using figures. Hereinafter, a case where ultrasonic therapy is performed on a patient who has a broken arm will be described.
First, the gel pad 100 to which the circular film sheet 103 is attached is peeled off from the rectangular film sheet 102 (see FIGS. 4A and 4B), and the exposed back surface 100a of the gel pad 100 is attached to the board surface 20a of the vibrator 20. Then, the circular film sheet 103 is peeled off from the surface 100b of the gel pad 100 to expose the surface 100b.
In this state, as shown in FIG. 5, the vibrator 20 with the gel pad 100 attached is positioned on the affected part, and the vibrator 20 is brought into contact with the arm so that the exposed surface 100b faces the arm.

Next, as shown in FIG. 6, a pair of band portions 50A and 50B are wound around the arm in a ring shape. More specifically, the band portion 50A is pulled along the skin so that the band portion 50B is on the inner side (arm side) with respect to the band portion 50A, and the band portion 50A is pulled as shown in FIG. Tension is applied to the band portion 50B via 50A and the holding portion 40.
Due to this tension, the pair of band portions 50A and 50B are elastically extended and deformed in a circumferential shape. At this time, in the gap C between the three hook-and-loop female dies 60A in the band portion 50A, the elastic band is deformed elastically without being restrained by the hook-and-loop fastener female dies 60A.

  In this manner, the hook-and-loop fastener female mold 60A and the hook-and-loop fastener male mold 60B are engaged with each other with the pair of band portions 50A and 50B elastically deformed. As shown in FIG. 7, an elastic return force acts on the pair of band portions 50A and 50B whose relative positions are constrained relative to each other in the radially inward direction. The vibrator 20 and the arm are in close contact with each other through the gel pad 100.

  Further, as shown in FIG. 8, when the pair of band portions 50A and 50B are pulled in a direction away from each other, and the one end portion 41a side of the cylindrical wall 41 is pulled in a direction away from each other, the locking claws 43A, 43B is displaced downward and toward the center of the cylinder hole (cylinder axis P). Thereby, the vibrator 20 is urged toward the arm, and the vibrator 20 is pressed against the arm.

  In this way, when ultrasonic waves are irradiated from the board surface 20a of the vibrator 20 in a state where the vibrator 20 and the arm are in close contact with each other via the gel pad 100, the ultrasonic waves are conducted to the affected area through the gel pad 100 to form bone tissue. Promote.

  Finally, after irradiating with ultrasonic waves for a predetermined time, the engagement between the female fastener 60A and the male male fastener 60B is released, and the ultrasonic treatment device 10 is removed from the arm. Then, the gel pad 100 is removed from the arm and the ultrasonic treatment is finished.

  As described above, according to the ultrasonic treatment system 1, since the pair of band portions 50A and 50B are made of an elastic body, when the pair of band portions 50A and 50B are elastically stretched and deformed, the arms are annularly wound around the arm. The vibrator 20 is urged toward the radially inward side (radial center side) by the elastic restoring force of the pair of band portions 50A and 50B and is brought into close contact with the arm. Thereby, even if the spring mechanism is omitted, the close contact between the arm and the vibrator 20 can be ensured, but the device configuration is simplified as compared with the case where the spring mechanism is provided. And a good feeling of use can be obtained.

  In addition, since the pair of band portions 50A and 50B are integral with the holding portion 40, the device configuration is further simplified, and further downsizing can be achieved.

  In addition, since the pair of band portions 50A and 50B and the holding portion 40 are formed of silicon rubber, the vibrator fixture 30 having excellent heat resistance, water resistance, and chemical resistance compared to other elastic materials can be configured. it can. Further, by adopting silicon rubber, the choices of coloring can be expanded and the design can be improved. Further, by adopting a transparent color, the visibility can be improved, and the positional relationship between the vibrator 20 and the arm can be grasped.

  Moreover, since the plurality of hook-and-loop fastener female molds 60A are continuously provided with a gap C in the extending direction of the pair of band portions 50A and 50B, the portion corresponding to the gap C in the pair of band portions 50A. Is elastically deformed without being influenced by the female fastener 60A. Thereby, the favorable elasticity of a pair of band part 50A can be ensured, and the arm and the vibrator | oscillator 20 can be made to contact | adhere favorably.

  Further, of the cylindrical wall 41, a pair of band portions 50A and 50B extend from the outer peripheral surface 41b to one end portion 41a of the cylindrical wall 41, and a pair of peripheral walls 42A and 42A facing each other on the other end portion 41c side. 42B is formed, and the locking claws 43A and 43B for restricting displacement of the vibrator 20 in the cylinder axis direction project from the respective inner peripheral surfaces 42a on the pair of peripheral walls 42A and 42B. , 50B are elastically extended and deformed, and when the one end portion 41a side of the cylindrical wall 41 is pulled in a direction away from each other, the locking claws 43A, 43B are displaced toward the ultrasonic irradiation direction and the radial center side. . Thereby, the vibrator 20 can be urged toward the arm, and the arm and the vibrator 20 can be in good contact with each other.

  In addition, since the gel pad 100 that conducts the ultrasonic wave irradiated from the vibrator 20 to the affected part is provided, the labor of cleaning can be reduced as compared with the case where a fluid gel is used. Furthermore, since the gel does not enter between the holding part 40 and the vibrator 20 and reduce the frictional force between the holding part 40 and the vibrator 20 as compared with the case where a fluid gel is used, It is possible to prevent the vibrator 20 from falling off and to hold the vibrator 20 well.

Note that the operation procedure shown in the above-described embodiment, various shapes and combinations of the constituent members, and the like are examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.
For example, in the above-described embodiment, the ultrasonic wave of the ultrasonic treatment device 10 is conducted to the affected area by applying the gel pad 100, but the ultrasonic wave of the ultrasonic treatment device 10 is applied by applying a fluid gel. Sound waves may be conducted to the arm. Even in this case, since the apparatus configuration of the ultrasonic therapy device 10 is simple, the labor of cleaning can be reduced.

  In the above-described embodiment, the case of performing ultrasonic treatment on a fracture occurring in the arm has been described. However, ultrasonic treatment is performed on each wound position (for example, a foot, a neck, a shoulder, etc.) of the body other than the arm. In this case, the present invention can be used. In particular, according to the present invention, since the device configuration of the ultrasonic therapy device can be simplified, as shown in FIG. 9, the device configuration is further downsized (the pair of band portions 50A and 50B are shortened). Thus, it is possible to easily realize the finger ultrasonic treatment device 70 suitable for ultrasonic treatment of the finger.

  In the above-described embodiment, the pair of band portions 50A and 50B are formed integrally with the holding portion 40. However, the pair of band portions 50A and 50B may be configured separately and attached to the holding portion.

  In the above-described embodiment, the restraining portion 60 is configured by the surface fastener female die 60A and the surface fastener male die 60B. For example, in one of the pair of band portions 50A and 50B, the band portion extends. The fitting holes may be connected in the direction, and the other part may be provided with a recess or a bar that can be inserted into the fitting hole to restrain the relative displacement of the pair of band parts 50A and 50B.

  Further, in the above-described embodiment, three hook-and-loop fastener female dies 60A are provided with a gap C therebetween, but the number thereof is arbitrary, two may be provided with a gap, or four or more may be provided. May be. Alternatively, a single configuration may be provided. Similarly, a plurality of hook-and-loop fastener male molds 60B may be provided with a gap.
