However, according to recent research, as shown in FIG. 11, the pain and numbness that occur in the body are different types of tissues that compose the body, such as fascia, ligament, nerve sheath and subcutaneous tissue (collectively, these tissues are collectively referred to as tissue). Fascia)) is caused by adhesion to each other and gliding failure. Fig. 11 is a longitudinal cross-sectional view of fascia along the depth direction from the surface of the body (Source: Kimura, Takagi, Namiki, Kobayashi, "Basics and clinical aspects of Fascia release guided by anatomy / motion / echo-muscle From membrane release to Fascia release ", Bunkodo).
The above-mentioned fascia adhesions are visualized as a piled-up echo image by echo examination. Therefore, as a method of eliminating the adhesion of fascia, a medical institution is currently performing a method in which a doctor inserts a physiological saline by piercing a needle with a needle while confirming the adhesion under echo. According to this procedure, injecting physiological saline causes one of the adhering tissues to float from the other and to be peeled off. As a result, the gliding property between tissues is improved, and pain and numbness can be eliminated. In addition, such a procedure by a doctor is called fascia hydro release.
However, since fascia hydro release is a medical procedure that can be performed only by a doctor, there are cases where even if you feel pain, you cannot immediately see a medical institution and receive treatment. Further, in the above-mentioned procedure, re-adhesion occurs at a certain rate depending on the patient, and therefore a useful tool capable of preventing this re-adhesion is necessary. Furthermore, since the above procedure is invasive, it is possible to eliminate pain and the like in a non-invasive and less invasive manner, and it is necessary to have a tool that can be performed by a person other than a doctor and self-care of the patient himself. It is believed that there is.

Therefore, it is possible to develop a massage method that can easily and non-invasively eliminate the adhesion of fascia and eliminate pain etc., and a massage jig as a tool for performing this massage method, regardless of the doctor. Is desired.
As such a massage method, for example, applying a force of a certain magnitude continuously for a certain time in a direction in which the body is obliquely inserted has been studied. This is because it is considered that the force continuously applied in the oblique direction is transmitted in the depth direction of fascia, so that one of the adhering tissues acts to float and separate from the other. Therefore, it is necessary for the massage jig to have a configuration that can realize the above-described action.

As to whether or not the above-described action can be realized, when the inventions disclosed in Patent Documents 1 and 2 are examined, first, in the invention disclosed in Patent Document 1, a vibrating vibrating head is brought into contact with the affected area for stimulation. Therefore, it is considered that the vibrating head exerts an action of repeatedly and intermittently impinging the vibrating head almost vertically from the upper side of the skin and transmitting the impact to the inside of the body. That is, the invention disclosed in Patent Document 1 acts so as to press the entire adhesion portion of fascia exclusively from above, which is different from floating and peeling one of the adhering tissues from the other. It can be judged that it is to exert the.
Therefore, according to the invention disclosed in Patent Document 1, it is considered difficult to sufficiently eliminate fascia adhesion.
Next, also in the invention disclosed in Patent Document 2, since it exerts the effect of pushing and pressing the affected area that is elaborate at the tip of the acupressure cartridge by the bath motion, the invention disclosed in Patent Document 1 It may be difficult to completely eliminate fascia adhesions.

  The present invention has been made in consideration of such a conventional situation, and it is possible to apply a certain amount of pressure continuously for a certain time in a direction obliquely entering the surface of the body. Thus, an object is to provide a massage jig capable of sufficiently eliminating fascia adhesion.

In order to achieve the above object, a first invention is a massage jig for massaging a body, which comprises a flexible material and a holder for holding the flexible material. Is composed of a contact end that comes into contact with the body, a holding end that is held by a holding body, and a body portion that is formed between the contact end and the holding end. An electric section connected to the mounting section and a housing for accommodating at least the electric section of the mounting section and the electric section are provided, and when the contact end is brought into contact with the surface of the body, the electric section holds the mounting section through the mounting section. By reciprocating the end with respect to the surface, the body part alternately bends in the opposite direction, and a force is periodically applied to the surface from the contact end, and this force is laminated in multiple layers of biological tissues. Dissociation between living tissues formed in the body by being transmitted in the depth direction of the body It can be characterized in that it is configured.
In the invention having such a configuration, an elastic body made of synthetic resin having flexibility is suitable as the flexible material, and specifically, for example, synthetic rubber used as an eraser can be considered. Further, a hard synthetic resin can be considered as the attachment portion of the holder.

In the invention of the above structure, when the contact end of the flexible member is brought into contact with the surface of the body, the contact end slides on the surface of the body due to friction when the electric part reciprocates the holding end with respect to the surface. Since this is suppressed, the body portion bends so as to be convex toward the advancing direction of the reciprocating motion. When the reciprocating motion continues in this state, the body part alternately bends in the opposite direction, so the restoring force that causes the flexible material to return to the original unbent state causes the contact end to generate a force to dig down the surface. Will be made. Therefore, the electric part can apply a force in the opposite direction to the depth direction of the surface alternately via the contact end.
It is considered that this force is transmitted in the depth direction of the body, that is, in the depth direction of fascia, and acts so as to float and detach one of the adhered living tissues from the other.
The electric section includes a rotation motor for rotating the shaft body and a motion conversion mechanism for converting the rotation motion of the shaft body into the reciprocating motion of the mounting portion. As the motion conversion mechanism, a rack and pinion is used. Mechanisms, crank mechanisms, planetary gear mechanisms, etc. are conceivable.

Next, in a second aspect based on the first aspect, the flexible material is formed in a flat plate shape, and the holding end is attached to the attachment portion so that the maximum surface of the flexible material is orthogonal to the reciprocating motion. The contact end has a chamfered first apex formed in a front view, and the first apex has a first side parallel to the width direction of the flexible material and has a tapered shape. It is characterized by
In the invention having such a configuration, in addition to the operation of the first invention, since the maximum surface of the flexible member formed in a flat plate shape is orthogonal to the reciprocating motion, when the mounting portion reciprocates, The part bends easily, and the degree of bending increases. Therefore, the above-mentioned restoring force increases and the force is efficiently applied to the surface of the body.
Further, the reason why the first top portion is formed to have a tapered shape when viewed from the front is to make the shape similar to the shape of a human fingertip. Due to this tapered shape, the contact end accurately contacts a portion occupying a small area on the surface of the body.
Therefore, in the second aspect of the invention, the force is transmitted to the pinpoint in the depth direction of the narrow surface through the contact end, and the adhesion of fascia in that portion is sufficiently lost.

Next, a third aspect of the present invention is the electric motor according to the first or second aspect, wherein the electric motor is supported by a rotation motor that rotates the shaft, a pinion supported by the shaft, and an inner wall of the housing. A rack-and-pinion mechanism including a rack in which pinions mesh with each other.The rack reciprocates in a direction orthogonal to the axial direction of the shaft body, and the mounting portion is fixed to the rack and reciprocates together with the rack. Characterize.
In the invention having such a configuration, the rotation motor is such that the rotation direction of the shaft body is only the same direction, or the rotation motor is capable of automatically switching between the forward and reverse directions at regular intervals. In the former case, for example, a double rack broken gear reciprocating mechanism in which a pinion is a broken gear and two racks are arranged to face each other with the broken gear sandwiched therebetween is conceivable.
In the invention of the above configuration, when the rotation motor rotates the shaft body, the mounting portion reciprocates together with the rack. Therefore, the contact end of the flexible material attached to the mounting portion is attached to the body. When brought into contact with the surface, the body portions bend in opposite directions and alternately bend. Therefore, also in the third invention, the same operation as that of the first or second invention is exhibited.

Further, in a fourth aspect based on the first or second aspect, the motorized portion includes a rotation motor that rotates the shaft body, a crank arm that rotates around the shaft body, and one end of the crank arm. A crank mechanism provided with a crank pin provided and a slider connected to the crank pin, wherein the mounting portion is connected to the other end of the slider to perform reciprocating motion.
Also in the invention having such a configuration, since the mounting portion reciprocates together with the other end of the slider as the shaft rotates, the same operation as that of the first or second invention is exhibited. It

The fifth invention is characterized in that, in any one of the first to fourth inventions, the flexible material is silicon rubber, and the type A hardness thereof is 20 to 80 degrees.
In the invention having such a configuration, the type A hardness means the hardness of the rubber when measured using a "type A" durometer for a general medium hardness rubber material defined by JIS K6253. It is a value.
In the invention of the above constitution, in addition to the action of the invention described in any one of the first to fourth aspects, the silicone rubber is excellent in elasticity, has no tackiness, is chemically stable, tasteless and odorless Since it also has a high insulating property, it is highly safe for the living body. Further, since the type A hardness is in a wide range of 20 degrees to 80 degrees, an appropriate hardness is selected according to the body part and symptoms such as pain.

And 6th invention is a holding | maintenance end in 2nd invention, The 2nd top part by which chamfering is carried out is formed in a front view, and this 2nd top part is parallel to the width direction of a flexible material. A second side, the length of the second side is greater than or equal to the length of the first side, and the mounting portion is a first top portion and a second top portion that can be fitted by exchanging the second top portion. The first fitting portion and the second fitting portion are formed.
In the invention having such a configuration, the length of the second side of the second top is equal to or greater than the length of the first side. This is for the purpose of allowing the second side to come into contact with a portion of the body surface that occupies a large area, such as the back or buttocks, at once.
In the above structure, in addition to the operation of the second invention, the first fitting portion and the second fitting portion are formed in the mounting portion, so that one mounting portion serves as both the contact end and the holding end. Can be replaced and held.

According to the first aspect of the present invention, a force can be periodically applied to the surface via the contact end in a direction obliquely entering the surface, and this force is transmitted in the depth direction of the fascia to cause adhesion. Adhesion formed in the depth direction of the surface of the body can be sufficiently eliminated by acting such that one of the living tissues floating and peeling from the other. Therefore, it is possible to eliminate pain and numbness that occur in the body.
Moreover, according to the first aspect of the invention, it can be used non-invasively even if not a doctor, and can be easily used outside the hospital, so that it is very convenient and effective.

  According to the second invention, in addition to the effect of the first invention, since the contact end has a tapered shape, the adhesion of fascia formed in the depth direction of the narrow surface is sufficiently eliminated, so that the neck or It can eliminate stiffness and pain in areas such as the intercostal space.

According to the third invention, in addition to the effect of the first or second invention, by adopting the rack-and-pinion mechanism as the electric section, it is possible to inexpensively manufacture the massage jig having a simple structure. .
Further, since the third invention has a simple structure and is lightweight, it can be used comfortably without feeling tired when being held by the patient or staff such as a medical institution.

  According to the fourth aspect of the invention, the same effect as that of the third aspect of the invention can be exhibited by adopting the crank mechanism as the electric drive section.

  According to the fifth invention, in addition to the effect of any one of the first to fourth inventions, silicone rubber is suitable as a flexible material to be brought into contact with the surface of the body because it has high safety for the living body. . In addition, silicone rubber is easily available since products having different type A hardness and thickness are on the market.

  According to the sixth invention, in addition to the effect of the second invention, it is convenient that both the contact end and the holding end can be easily replaced and held by one mounting portion. Therefore, the first top having a tapered shape and the second top not having a tapered shape can be brought into contact with the surface of the body at desired timings. Therefore, regardless of the area occupied by the surface of the body, the adhesion of fascia can be eliminated by using one flexible material.

It is a longitudinal cross-sectional view of fascia along the depth direction from the surface of the body.

A massage jig according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 10. FIG. 1A is a front view of a massage jig according to an embodiment, and FIG. 1B is a view taken in the direction of arrow A in FIG. 2 (a) and 2 (b) are a front view and a side view of an example of a flexible material forming a massage jig according to an embodiment, and (c) and (d) are flexible views, respectively. It is a front view about the other example of a performance material.
As shown in FIGS. 1A and 1B, a massage jig 1 according to an embodiment is a massage jig for massaging a body, and includes a flexible member 2 and a flexible member 2. A holder 3 for holding the flexible material 2 is provided. The flexible material 2 is a silicon rubber formed in a flat plate shape, and has a type A hardness of 30 to 40 degrees. Such type A hardness is generally equivalent to the hardness of silicone rubber used as an eraser, and can be easily bent with a finger.
The flexible member 2 is formed in a substantially rectangular shape in a front view, and has a contact end 2A that comes into contact with the body, a holding end 2B held by the holding body 3, and between the contact end 2A and the holding end 2B. The body portion 2C is formed. The specific size of the flexible member 2 is as shown in FIGS. 2 (a) and 2 (b).

  As shown in FIGS. 2A and 2B, the contact end 2A has a chamfered first top 4 formed in a front view. The first top portion 4 has a first side 4a parallel to the width direction of the flexible member 2 and both ends of the first side 4a and a length parallel to the long axis direction of the flexible member 2. It is composed of first oblique sides 4b and 4b that connect the sides 2a and 2a, respectively, and has a tapered shape that is as sharp as the shape of the fingertip.

Further, the holding end 2B is formed with a chamfered second top portion 5 in a front view. The second apex 5 has a second side 5a parallel to the width direction of the flexible member 2 and a second oblique side 5b connecting both ends of the second side 5a and the long sides 2a, 2a. , 5b and has a tapered shape.
Here, the length of the second side 5a is equal to the length of the first side 4a, but the second angle θ ₂ , between the two ends of the second side 5a and the second oblique sides 5b, 5b, respectively. Since the magnitude of θ ₂ is larger than the magnitude of the first angles θ ₁ and θ ₁ formed by both ends of the first side 4a and the first hypotenuses 4b and 4b, respectively, the second top portion 5 has It does not have a tapered shape as sharp as the top portion 4.
However, in the first top portion 4 and the second top portion 5, the length of the second side 5a is irrespective of the magnitude relationship between the magnitude of the first angle θ _{1 and} the magnitude of the second angle θ _2. It is sufficient that the length is equal to or longer than the length of the first side 4a.

  Further, as shown in FIGS. 2C and 2D, a longer flexible material 6 or a flexible material 7 may be used instead of the flexible material 2. The specific sizes of the flexible members 6 and 7 are as shown in FIGS. 2C and 2D, respectively, and the material is the same silicone rubber as the flexible member 2.

Referring again to FIGS. 1A and 1B, the holding body 3 includes a mounting portion 8 to which the holding end 2B is mounted, an electric portion 9 connected to the mounting portion 8, and a mounting portion 8. The housing 10 is provided with an opening 10a through which the electric motor 9 is reciprocally exposed. Further, the housing 10 accommodates a battery 11 that supplies electric power to the electric section 9 via a wiring (not shown). It should be noted that the housing 10 may house a part of the mounting portion 8 near the rack 14 together with the electric portion 9.
The mounting portion 8 is formed with a concave fitting portion 8a into which the second tapered top portion 5 can be fitted. However, the first fitting portion 8a may be formed in a shape that allows the first top portion 4 to be fitted therein.
The electric section 9 is a rack and pinion mechanism that includes a rotation motor 12 that rotates the shaft 12a, a pinion 13 supported by the shaft 12a, and a linear rack 14 that meshes with the pinion 13.
Of these, the rotation motor 12 is fixed to the inner wall of the housing 10 by a fixing member (not shown), and the forward and reverse directions of the rotation of the shaft body 12a can be automatically switched at regular intervals. The battery 11 is also housed inside the housing 10 by being housed in a case (not shown).

  Further, as shown in FIG. 1B, the rack 14 is composed of a base portion 14a and a meshing portion 14b having a meshing surface with which the pinion 13 meshes, and a direction orthogonal to the axial direction of the shaft body 12a (X direction in the drawing). ) Is arranged along. Further, the base portion 14a is locked in the inner wall of the housing 10 by being housed inside the long guide rail 15 fixed to the inner wall of the housing 10 along the X direction. As a result, the rack 14 reciprocates along the X direction orthogonal to the axial direction of the shaft 12a as the shaft 12a rotates in the forward and reverse directions, and is supported by the inner wall of the housing 10 for massage. Even if the jig 1 is freely moved, the meshing portion 14b is not separated from the pinion 13.

Further, the mounting portion 8 has a base end screwed to the outer side surface of the meshing portion 14b with, for example, a screw (not shown). Therefore, the mounting portion 8 reciprocates along with the rack 14 along the X direction shown in FIG. In addition, in FIG. 1B, the X direction is the depth direction of the drawing.
Next, the holding end 2B is attached to the attachment portion 8 so that the maximum surface 2b of the flexible member 2 formed in a flat plate shape is orthogonal to the X direction of the reciprocating motion. Therefore, when the contact end 2A is brought into contact with the surface of the body and the mounting portion 8 is reciprocally moved, the body portion 2C is easily bent and the degree of bending is increased.

Next, the operation of the massage jig according to the embodiment of the present invention will be described in detail with reference to FIG. FIG. 3 is a schematic diagram for explaining the operation of the massage jig according to the embodiment. The components shown in FIGS. 1 and 2 are denoted by the same reference numerals in FIG. 3 and their description is omitted.
In the initial contact end 2A of the flexible member 2 in which the electric part 9 is not in operation, only the first side 4a of the first top 4 is brought into contact with the surface 50 of the body. A force is evenly applied from above in the thickness direction of the side 4a. However, as shown in FIG. 2, in this state, when the motorized portion 9 slides the holding end 2B through the mounting portion 8 in the lateral direction parallel to the surface 50 (X ₁ direction in FIG. 3), The front side 4a of No. 1 is prevented from sliding on the surface 50 along the X ₁ direction by friction with the surface. More specifically, the position of the first side 4a that comes into contact with the surface 50 moves toward the advancing direction (X ₁ direction) of the holding end 2B, but the first side 4a itself slides in the X ₁ direction. It never moves.
On the other hand, since the holding end 2B moves in the X ₁ direction with the height from the surface 50 to the second side 5a (see FIG. 3) being constant, the body portion 2C of the flexible material 2 is X ₁ It will be bent so as to be convex toward the direction side.

After maximally bending the body 2C so as to be convex in the X ₁ direction, the electric portion 9 moves the holding end 2B to the surface 50 while keeping the first short side 4a in contact with the surface 50. When the slide portion is slid parallel to the lateral direction (X ₂ direction in FIG. 3) opposite to the X ₁ direction, the body portion 2C tries to restore to the original non-bent shape. Therefore, in the first side 4a, the position for transmitting the above-mentioned restoring force, that is, the position of the first side 4a in contact with the surface 50 will move to the advancing direction (X ₂ direction) side of the holding end 2B. And
Therefore, when the contact end 2A is viewed from the side, the contact end 2A generates a force F ₁ for digging the surface 50 into a substantially arc shape due to the restoring force of the body 2C to return to the original unbent state. Become. It is considered that this force F ₁ is transmitted in the depth direction of the body, that is, the depth direction of fascia, and thereby exerts an effect of floating one of the adhered biological tissues from the other and peeling it off. Note that such an effect is called a lift-up effect.

Next, after the body portion 2C is flexed to the maximum in the direction of the X ₂ direction and the electric portion 9 slides the holding end 2B again in the X ₁ direction with respect to the surface 50, the contact end 2A is moved. A force F ₂ for digging the surface 50 in a substantially arc shape in the direction opposite to the force F ₁ is generated.
Thereafter, when the holding end 2B is repeatedly slid by the electric portion 9 to bring the contact end 2A into contact with the surface 50 of the body, the electric portion 9 causes the holding end 2B to be parallel to the surface 50 via the attachment portion 8, That is, by reciprocating in the X ₁ direction and the X ₂ direction, the body portion 2C is alternately bent in the opposite direction, and the force F ₁ , F _{2 is} periodically applied to the surface 50 from the first side 4a of the contact end 2A. Is applied, and the forces F ₁ and F ₂ are transmitted in the depth direction of the body in which a plurality of types of biological tissues are laminated in a multilayer structure, and a lift-up effect is exerted. Therefore, the adhesion between the living tissues formed on the body can be resolved. In addition, by appropriately adjusting the magnitude of the force applied from above the surface 50 in consideration of the value of the type A hardness of the flexible material 2, the body part, and the symptom or condition of the patient, the contact end 2A Can be strongly adhered to the surface 50, or the surface 50 can be touched without slipping.
Further, by reciprocating the flexible member 2 parallel to the surface 50, it is possible to sense fascia adhesion that cannot be sensed with a fingertip as vibration through the flexible member 2. .

Subsequently, an actual example of the lift-up effect of the massage jig 1 will be described with reference to FIGS. 4 to 8. FIG. 4A and FIG. 4B are images of echo examination before and after the massage jig according to the example is used for the surface layer fascia on the body surface.
As shown in FIGS. 4 (a) and 4 (b), the treatment with the massage jig 1 was performed on the abdominal surface layer fascia of a patient who complained of abdominal pain. The force for pressing the surface 50 of the abdomen is such a strength that the surface 50 is recessed by about 10 mm, and the distance that the mounting portion 8 slides is the body portion 2C in the X ₁ direction and the X ₂ direction (see FIG. 3, respectively). It was set so as to bend by 1 cm at the maximum. In addition, a first apex (not shown) having the same shape as the second apex 5 was brought into contact with the surface 50 of the abdomen, instead of the first apex 4 having a tapered shape like a fingertip.
As a result, the area of the subcutaneous tissue superficial layer region S ₁ in FIG. 4B after the treatment was larger than the area of the same region in FIG. 4A before the treatment. Furthermore, in the deep region S ₂ of the subcutaneous tissue, it was confirmed that the adhesion site of fascia, which was observed as a piled-up echo image (a site showing a white high signal), almost disappeared. By contacting the first top portion having the same shape as the second top portion 5 in this manner, the contact end 2A can contact the portion of the body surface that occupies a large area at one time. In the patient, the abdominal flexibility was improved and the abdominal myalgia disappeared after the treatment.

Next, FIG. 5 (a) and FIG. 5 (b) are images of echo examination before and after the massage jig according to the example is used for the deep fascia on the body surface.
As shown in FIGS. 5 (a) and 5 (b), the treatment with the massage jig 1 was performed on the forearm interosseous fascia of a patient who complained of difficulty in moving the forearm and fingers. The force for pressing the surface 50 of the forearm is such that the surface 50 is recessed by about 10 mm, and the distance that the mounting portion 8 slides is the body portion 2C in the X ₁ direction and the X ₂ direction (see FIG. 3, respectively). It was set so as to bend by 1 cm at the maximum. Further, the first top portion 4 having a tapered shape was brought into contact with the surface 50 of the forearm.
As a result, the area of the triangular region S ₃ connecting the median nerve, radius and ulna in FIG. 5 (b) after the operation was larger than the area of the same region in FIG. 5 (a) before the operation. Therefore, it can be judged that the adhesion of fascia between the forearm interosseous fascia and the radius was improved, and it is considered that the adhesion up to about 3 cm from the surface 50 to the deep part was improved. In addition, in the patient, it was confirmed that the range of pronation of the forearm and the range of flexion of the fingers were expanded after the treatment.

Furthermore, FIG. 6A and FIG. 6B are images of echography when the massage jig according to the example is used for nerve tissue that is the vascular structure of the buttocks.
As shown in FIGS. 6 (a) and 6 (b), a massage jig 1 was applied to the buttocks of a patient who complained of walking difficulty due to low back pain. The force that presses the surface 50 of the buttocks is such that the surface 50 is recessed by about 10 mm, and the distance that the mounting portion 8 slides is the body portion 2C in the X ₁ direction and the X ₂ direction (see FIG. 3 respectively). It was set so as to bend by 1 cm at the maximum. Further, a first top portion (not shown) having the same shape as the second top portion 5 was brought into contact with the surface 50 of the buttocks, instead of the first top portion 4 having a tapered shape like a fingertip.
As a result, the nerves and blood vessels in FIG. 6 (b) after the treatment are separated from each other to make the boundaries clear, and the area of the nerve or blood vessel region S ₄ is the same as that in FIG. 6 (a) before the treatment. It was larger than the area of the same region. Such an effect is called a vascular rolling effect. In addition, in the patient, the effect of improving walking difficulty was confirmed after the treatment.
Further, by applying the above-described vascular rolling effect to the shunt blood vessel for dialysis, it is expected that the effect of maintaining the flexibility of the shunt part is improved, the prevention of occlusion and the ease of puncture are improved.

Next, FIG. 7 (a) and FIG. 7 (b) are images of echo examination before and after the massage jig according to the example is used on a blood vessel of the neck.

(Refer to the reference), each of them was set so as to bend by a maximum of 1 cm. Further, the surface 50 of the neck portion was brought into contact with the first top portion 4 having a tapered shape like a fingertip.
As a result, the area of the internal jugular vein region S ₅ in FIG. 7B after the treatment was larger than the area of the same region in FIG. 7A before the treatment. Therefore, the stenosis at the same site was improved and the inner diameter of the internal jugular vein was expanded. As described above, by bringing the tapered first apex 4 into contact with the fingertips, the adhesion of fascia formed in the depth direction of the narrow surface 50 is sufficiently eliminated, so that the stiffness of the neck or intercostal areas is reduced. Can relieve pain. In the patient, dizziness symptoms disappeared immediately after the operation. Further, since it is difficult to perform fascia hydro release around the cervical blood vessel from the viewpoint of safety, the effect of eliminating adhesion by the massage jig 1 is particularly effective.

Next, FIG. 8A and FIG. 8B are images of an echo examination before and after using the massage jig according to the embodiment for edema of the lower leg, respectively.
As shown in FIGS. 8A and 8B, the lower leg of the patient who developed edema was treated with the massage jig 1. The force for pressing the surface 50 of the lower leg should be such a strength that the surface 50 is recessed by about 2 to 3 mm, and the distance by which the mounting portion 8 slides is the body portion 2C in the X ₁ direction and the X ₂ direction (see FIG. 3 respectively). (Refer to the reference), each of them was set so as to bend by a maximum of 1 cm.
As a result, the area S ₆ of the lymphatic vessels and venules in FIG. 8B after the treatment was larger than the area of the same region in FIG. 8A before the treatment. Therefore, the stenosis at the same location was improved, and the lymph vessels and blood vessels could be clearly observed. In the patient, improvement of edema was confirmed after the treatment.
