The fitting portion 12 is a member that is provided in a fixed state on the proximal end side of the massage member 2, and is formed in a cylindrical shape. The cymbal press fitting portion 12 is disposed such that its axial center is slightly inclined in the left-right direction, and the cymbal press portion 11 to be described later is rotatably fitted inside.

The projecting portion 11 is a cylindrical member that can be inserted into the inside of the kneading fitting portion 12, and is disposed in the same direction as the fitting portion 12 such that the axis thereof is inclined slightly from the left-right direction. The protrusion 11 is formed such that its outer diameter and the inner diameter of the fitting portion 12 are substantially equal to each other, and the inside of the fitting portion 12 can be inserted.

Specifically, the inclined outer surface of the protruding portion 11 is formed with an inclined cam surface 16 that is inclined with respect to the axial center of the rotating shaft 10, and the locking fitting portion 12 is formed to be slidably fitted to the inclined cam surface 16. That is, the inclined cam surface 16 is rotated about an axis that is inclined in the direction of the axis of the rotary shaft 10, and the click fitting portion 12 can be guided along a circumferential track that is eccentric to the axis of the rotary shaft 10. Therefore, when the rotary shaft 10 rotates, the snap fitting portion 12 rotates about an axis that is inclined from the axis of the rotary shaft 10.

Further, the pressing portion 12 is provided with a rotation preventing mechanism 17 for restricting the rotation of the folding fitting portion 12 following the protruding portion 11, in other words, for restricting the pressing of the massage members 2L, 2R The rotary shaft 10 is rotated.

The grasping and urging means 7 are respectively disposed corresponding to the left and right squatting massage members 2L, 2R. In the present embodiment, one set is provided on each of the right and left sides. Similarly to the application member 9, the grasping operation member 7 is formed into a thick disc type or a spherical shape using a hard rubber or a synthetic resin, and is considered to be even if the user's operation site is pushed into the operation. Between the pieces 9, it will not hurt the site.

Further, the other end portion (base end portion) of the grasping massage member 8 is provided with a pivot pin 27 for swinging the gripping massage member 8 to the massage portion. The pivot pin 27 is disposed on the proximal end side (rear end side) in the longitudinal direction of the massage portion, and the one end side end portion of the gripping massage member 8 is wound around the other side end portion in the left-right direction. The shaft is supported in a freely rotatable manner.

Further, a slit-like long hole 28 is formed in the middle of the longitudinal direction of the grasping massage member 8. The long hole 28 is formed to be pressed along the above The longitudinal direction of the friction member 8 is formed on the upper surface and the lower surface of the grasping massage member 8, and is formed so as to penetrate the inside of the massage member 8 in the vertical direction. Further, the formation width of the long hole 28 is larger than the outer diameter of the distal end side of the crank member 26 (which will be described later in detail), and the front end side of the crank member 26 can be freely inserted into the hole. At the same time, the inside of the long hole 28 is provided on one side (the other end side) of the pivot pin 27, and a coupling pin 29 for coupling the front end of the crank member 26 is provided. The connecting pin 29 is attached to the left and right direction, and the front end of the crank member 26 is coupled to the gripping massage member 8 so that the front end of the crank member 26 is rotatable around the axis in the left-right direction.

On the other hand, the grip protruding portion 23 constituting the grip driving unit 22 is attached to the rotating shaft 10 (the same rotating shaft 10) that imparts a rotational driving force to the rubbing massage member 2.

The grip protrusion portion 23 is a disc-shaped member disposed on the inner side in the width direction of the protrusion portions 11L and 11R of the rotation shaft 10 described above. The left gripping protrusion 23L is disposed on the right side of the left side pressing protrusion 11L, and the right side gripping protrusion 23R is disposed on the left side of the right side pressing protrusion 11R.

The grip protrusion portion 23 is also attached to the rotary shaft 10 in an eccentric state similarly to the cymbal press portion 11. Specifically, as shown in FIG. 4, when the pressing portion 11 is eccentric toward the upper rear side from the center of the base end side of the massage members 2L, 2R, as shown in FIG. 3B, the gripping protrusion 23 is pressed from the side. The center of the proximal end side of the massage members 2L and 2R is eccentric to the lower rear side, and the eccentric direction of the protrusion portion 11 and the grip protrusion portion 23 constitutes an angular difference of about 90°, and forms a eccentric shape in mutually different directions. .

Further, the outer peripheral surface of the gripping protrusion 23 is also formed with a cam. Face 24. The cam surface 24 is formed along the cylindrical rail, and is formed to guide an annular fitting portion 25, which will be described later, along a circumferential track that is eccentric to the rotating shaft 10, the cylindrical rail surrounding its orientation and the rotation. The axis of the shaft 10 is an inclined axis.

Further, the direction in which the cam surface 24 is inclined with respect to the axial center of the rotating shaft 10 is the same as the direction in which the inclined cam surface 16 is inclined with respect to the axial center of the rotating shaft 10. Therefore, the cam surface 24 and the inclined cam surface 16 are parallel to each other in the same direction. That is, the crank member 26 of the annular fitting portion 25 guided along the cam surface 24 and the massage member 2 of the click fitting portion 12 guided along the inclined cam surface 16 are oriented at the same inclination. Direction, so these components do not interfere with each other during rotation.

The annular fitting portion 25 is a cylindrical member that can be sleeved outside the grip protrusion portion 23. The annular fitting portion 25 is formed with a protruding portion insertion hole 30 into which the above-described grip protruding portion 23 can be inserted in a penetrating manner in the left-right direction. By fitting the gripping projection 23 into the projection insertion hole 30, the cam surface 24 of the gripping projection 23 is brought into contact with the inner peripheral surface of the projection insertion hole 30 in a surface shape, and the crank member 26 can be along the opposite rotation axis. 10 eccentric surround tracks are guided.

The crank member 26 is a rod-shaped member that extends from the outer peripheral surface of the annular fitting portion 25 toward the outer side of the radial direction (in the direction in which the longitudinal direction of the massaging member 2 is pressed). The proximal end side of the crank member 26 is fixed to the outer peripheral side of the annular fitting portion 25, and the distal end side of the crank member 26 is pivotally supported by the coupling pin 29 of the grasping massage member 8 about the axis in the left-right direction. .

When the rotary shaft 10 is rotated, the gripping projection 23 attached to the inner side (the inner side in the width direction) of the projecting portion 11 of the rotary shaft 10 is also rotated. Although the gripping protrusion 23 is formed in a disk shape, as described above, the rotating shaft 10 penetrates a position eccentric from the center of the disc shape. Therefore, when the rotary shaft 10 rotates, the grip protrusion 23 is rotated about the axis of the rotary shaft 10 in an eccentric state.

However, the front end side of the crank member 26 that is sleeved on the above-described gripping protrusion 23 is pivotally supported by the joint pin 29 of the gripping massage member 8, and the gripping massage member 8 is coupled to the massage by the pivot pin 27. Member 2. Therefore, the crank member 26 can have its tip end side pivoted about the axis in the left-right direction around the pivot pin 27, but cannot rotate around the axis of the rotary shaft 10 and the grip protrusion 23. . Therefore, with the crank member 26 sleeved on the grip protrusion 23, the distance from the axis of the rotary shaft 10 to the front end of the crank member 26 changes in length, so that the crank member 26 cooperates with the rotation of the rotary shaft 10. And advance and retreat forward and upward.

For example, as shown in FIG. 5A, the gripping projection 23 which is eccentric with the rotary shaft 10 is rotated, and in the case where the crank member 26 is retracted rearward and downward, the crank member 26 is pulled down, and the position of the joint pin 29 is moved downward.

Then, by gripping the massage member 8 to swing downward, it is set to grasp The grasping operation member 7 at the front end of the kneading massage member 8 is separated from the squeezing operation member 9.

However, as shown in FIG. 5B, when the gripping projection 23 continues to rotate and the crank member 26 protrudes forward and upward, the crank member 26 is pushed out, the position of the coupling pin 29 is moved upward, and the gripping massage member 8 is grasped. The upper side is swung around the pivot pin 27. Then, by grasping the upward movement of the massage member 8, the grasping operation member 7 provided at the front end of the grasping massage member 8 approaches the squeezing operation member 9.

In other words, in the massaging apparatus 1 of the first embodiment, when the rotating shaft 10 is rotated, the gripping tool 7 repeatedly moves away from and closes to the pressing member 9, so that the massaging device 1 is disposed such that The operation site is located between the grasping and applying member 7 and the urging member 9, and a massage such as a grasping operation portion (for example, a shoulder) can be performed.

On the other hand, the midway side of the longitudinal direction of the gripping massage member 8 (the gripping massage member 8 which is biased toward the one end side from the pivot pin 27) is formed with a through hole through which the swing pin 39 can pass. The through hole penetrates the swing pin 39 which is used to join the massage member 2 and the massage member 8. By the swing pin 39, the massaging member 2 and the gripping massage member 8 can be pivotally pivoted about an axis in the left-right direction.

As shown in FIG. 10A, FIG. 12A and FIG. 12B, the grip driving unit 22 of the massaging apparatus 1 of the third embodiment is provided with a grip protrusion 23 that is attached to the rotary shaft 10 in an integrally rotatable manner. The gripping protrusion The outer peripheral surface of the 23 is formed with a cam surface 24, and the cam surface 24 is provided with a rail that is eccentric and inclined with respect to the axial center of the rotating shaft 10. The cam surface 24 of the grip protrusion portion 23 is fitted with an annular fitting portion 25 that obtains a rotational driving force of the rotary shaft 10 by the grip protrusion portion 23. Further, the annular fitting portion 25 is provided on the proximal end side of the crank member 26 so as to rotate integrally with the crank member 26, and the crank member 26 has a rotational driving force transmitted by the annular fitting portion 25 on the proximal end side. The function to the front end side (the gripping massage member 8 on the front end side).

The above-described gripping protrusion 23 is a short-shaped and large-diameter cylindrical member, and the rotating shaft 10 penetrates in the left-right direction at a position shifted from the center to the outer peripheral side of the gripping protrusion 23 . Further, similarly to the inclined cam surface 16 of the protruding portion 11, the outer peripheral surface of the grip protruding portion 23 is formed with a cam surface 24, and the cam surface 24 is provided with a rail inclined with respect to the axial center of the rotating shaft 10. Specifically, the rotating shaft 10 is in an eccentric state while intersecting the axis of the gripping protrusion 23 in an inclined state. Further, the direction in which the gripping projection 23 is inclined with respect to the rotary shaft 10 is provided in the same manner as the direction in which the projection portion 11 is inclined with respect to the rotary shaft 10 in any portion in the circumferential direction.

The above-described crank member 26 is a member in which a plate-like member that protrudes outward from the outer circumferential surface of the annular fitting portion 25 is formed in a cylindrical annular fitting portion 25, and is fitted at the proximal end side. The cylindrical annular fitting portion 25 of the cam surface 24 of the protruding portion 23 is gripped. The annular fitting portion 25 is a cylindrical member that can be loosely fitted to the cam surface 24 from the outside, and is rotatably attached to the cam surface 24.

Further, the curved piece protrudes outward from the annular fitting portion 25 The front end of the shank member 26 is formed with a through hole through which the pivot pin 27 is inserted so as to penetrate the crank member 26 in the left-right direction, and is inserted into the through hole and the pivot pin through hole through the pivot pin 27 in a communicating state, so as to be grasped. The proximal end side of the kneading massage member 8 is rotatably coupled to the distal end side of the crank member 26 about an axis in the left-right direction.

When the massage device 1 of the third embodiment is used for the grasping massage, first, the rotary shaft 10 is rotated about the axis in the left-right direction by a drive motor (the drive motor 15 is driven). Then, the rotating shaft 10 is rotated about the axis in the left-right direction, and the click protrusion portion 11 and the grip protrusion portion 23 attached to the rotating shaft 10 are also integrally rotated with the rotating shaft 10.

At this time, since the inclined cam surface 16 of the click portion 11 has a rail that is inclined with respect to the axis of the rotating shaft 10, when the rotating shaft 10 rotates, the inclined cam surface 16 draws a track that oscillates in the left-right direction. The pressing portion 11 is simultaneously rotated. However, since the rotating shaft 10 is pressed around the axial center of the protruding portion 11, the state of being excessively eccentric is not formed. Therefore, even if the inclined cam surface 16 is meandered in the left-right direction, there is almost no change in the radial direction.

However, with respect to the above-described squeezing projection portion 11, the cam surface 24 of the gripping projection portion 23 is not only inclined to the axial center of the rotary shaft 10 but also eccentric, so that the rotary shaft 10 penetrates from the center of the gripping projection portion 23 The position offset to the outer circumference side. Therefore, when the rotary shaft 10 rotates, the cam surface 24 not only snakes in the left-right direction like the inclined cam surface 16, but also changes the track in the radial direction, so that the grip protrusion 23 is eccentrically around the axis of the rotary shaft 10. Rotate.

However, the crank structure that is sleeved on the above-mentioned gripping protrusion 23 The front end side of the member 26 is pivotally supported by a pivot pin 27 provided on the proximal end side of the grasping massage member 8, and the grasping massage member 8 is connected to the massage by the swing pin 39 provided on the midway side in the longitudinal direction. The front end side of the protruding portion 44 of the member 2. Therefore, the crank member 26 cannot rotate around the axis of the rotary shaft 10 together with the grip protrusion 23 even if the front end side of the front end side is swingable about the axis in the left-right direction around the swing pin 39. Therefore, with the crank member 26 sleeved on the grip protrusion 23, the distance from the axis of the rotary shaft 10 to the front end of the crank member 26 (the pivot pin 27) varies in length, so that the rotation With the rotation of the shaft 10, the crank member 26 sometimes protrudes forward and upward, and sometimes backwards toward the lower rear side.

For example, as shown in FIG. 12A, when the gripping projection 23 that is eccentric with the rotating shaft 10 is rotated, and the crank member 26 is moved to the upper front side, the front end side of the crank member 26 is pulled upward. Then, the position of the pivot pin 27 is moved to the front upper side, and the gripping massage member 8 is swung in the direction in which the gripping member 7 is squatted (the direction indicated by the arrow of Fig. 12A) centering on the swing pin 39. Then, by gripping the massage member 8 to swing downward, the grasping operation member 7 provided at the front end of the grasping massage member 8 is separated from the urging member 9.

However, as shown in Fig. 12B, the gripping projection 23 continues to rotate, and when the crank member 26 moves to the lower rear side, the front end side of the crank member 26 is pushed down to the rear. Then, the position of the pivot pin 27 is moved to the lower rear side, and the gripping massage member 8 swings the gripping member 7 toward the upper jaw direction (in the direction indicated by the arrow of Fig. 12B) around the swing pin 39. Then, by grasping the upward movement of the massaging member 8, the grasping operation member 7 provided at the front end of the grasping massage member 8 approaches the squeezing operation member 9.

In the massage device according to the third embodiment, when the rotary shaft 10 is rotated, the posture of the gripping massage member 8 can be switched between the disengaged state and the approaching state, and the grasping and applying member 7 is pressed against the surgical member 9 When it is close to the time, the user's operation site can be inserted between the surgical device 9 and the grasping operation member 7 to perform a grasping massage.

In the massaging apparatus 1 according to the third embodiment, the massage member 2 is formed to be coupled to the upper end of the rotating shaft 10 by the surgical member 9, and the base end of the grasping massage member 8 is coupled to the rotating shaft. The lower end of 10 (the front end of the protruding portion 44) is constructed. Therefore, in the massage device 1 of the third embodiment, the grasping operation is performed in comparison with the first embodiment or the second embodiment in which the manipulation member 9 and the grasping massage member 8 are provided on the same side of the rotating shaft 10. The distance between the piece 7 and the cymbal 9 can be increased in the up and down direction or in the anteroposterior direction. That is, when the grasping and applying member 7 approaches or leaves the pressing member 9, the swinging range of the grasping and applying member 7 can be expanded in the up and down direction, and the force can be applied to the operating portion according to the degree of the swinging range. The advantages of massage.

[Fourth embodiment]

Next, the massage device 1 according to the fourth embodiment will be described.

The massaging apparatus 1 of the fourth embodiment shown in Fig. 14 has a mechanism (massage mechanism) similar to that of the third embodiment shown in Fig. 10A and the like, and is provided with a gripping mechanism capable of performing a grasping massage on a user's operation site. Massage member 8.

However, the massage device 1 of the fourth embodiment is different from the massage device of the third embodiment in that the massage device 1 of the fourth embodiment maintains the gripping tool 7 substantially close to the state in which the applicator member 9 is pressed. While pressing the applicator member 9 and the grasping and applying member 7 in the width direction from one side to the other Reciprocating on one side. That is, when the subject is a shoulder, the grasping operation member 7 and the manipulation member 9 can substantially maintain the state of grasping the shoulder while moving toward the neck while moving closer to the neck, as in the case of the operation site. Apply a small amount of gripping massage continuously.

According to this method, the approaching of the grasping and applying member 7 can be repeated in a short time, and the grasping portion of the surgical site can be grasped and the grasping and grasping operation member 7 can be released, and the grasping action can be released, so that the surgical device can be released. 9 and the grasping operation member 7 can reciprocate from one side to the other side in the width direction, thereby continuously performing a small-distance grasping massage on the operation site. This small-amplitude grasping massage has an excellent effect of improving blood flow through a particularly severely tightened surgical site.

In the massage device 1 of the fourth embodiment, the rotation direction of the rotary shaft 10 is alternately switched to the positive direction and the reverse direction in the rotation angle of less than one rotation, whereby the operation member 9 and the grasping operation are performed on the intrusion A short-range grasping massage is continuously performed on the site of operation between the pieces 7.

Specifically, the massage device 1 according to the fourth embodiment is provided with a control unit (not shown) that controls the rotation direction of the rotary shaft 10, and can control the rotation of the drive motor 21 that rotates the rotary shaft 10 by the control unit. To carry out the above-described continuous grasping massage.

Further, the rotating shaft 10 is provided with a rotation measuring unit (not shown) that can measure the rotation angle or the number of rotations of the rotating shaft 10. The rotation measuring unit measures the rotation angle of the rotating shaft 10, and based on the measured rotation angle, causes the control unit to perform control of the driving motor 21.

The rotation measuring unit may be an optical encoder which is formed with a notch or the like on the outer edge of the circular plate provided on the rotating shaft 10, and is passed by the pair. The photosensor of the notch is detected by light to detect the rotation angle or the number of rotations of the rotating shaft 10. Further, the configuration of the control unit described above is based on the rotation angle of the rotating shaft 10 detected by the rotation measuring unit, and the rotation of the rotating shaft 10 is switched to the positive direction and the reverse direction.

That is, the control unit stores a rotation angle indicating that the gripping operation member 7 is in the closest state to the operation member 9 and the state in which the grasping operation member 7 is closest to the operation member 9 (angle) 0°) as a reference, in the range from +45° to -45° from the closest rotation angle, the rotation of the rotary shaft 10 is alternately switched to the positive direction and the reverse direction, and the operation can be performed on the intrusion A short-range grasping massage is continuously performed on the surgical site between the piece 9 and the grasping operation member 7.

The range of the rotation angle of the forward rotation and the reverse rotation may be set to an angle other than the above 45° as long as it is a rotation angle that is less than one rotation. The rotation direction of the rotary shaft 10 is alternately switched to the positive direction and the reverse direction every rotation angle of less than one rotation.

If the rotation direction of the rotary shaft 10 is switched in such a range of rotation, the gripping member 7 can be maintained in the width direction while maintaining the state in which the gripping member 7 is substantially close to the urging member 9. Reciprocate from side to side. That is, when the operation site is a shoulder, the posture of the applicator member 9 and the grasping operation member 7 can be substantially maintained while the shoulder is applied, and the neck portion is brought close to the neck when the operation member 9 and the grasping operation member 7 are grasped. Sometimes moving away from the neck, and a small amount of grasping massage is continuously applied to the site.

Next, a method of continuously performing a gripping massage which is actually a short cycle will be described using the massaging apparatus 1 of the fourth embodiment described above.

For example, when the rotation angle measured by the rotation measuring portion reaches the reference value (0°), the state in which the grasping operation member 7 is closest to the urging member 9 is formed, and the grasping operation member 7 and the urging member 9 are the most A state in which the user's operation site can be invaded.

Thereafter, before the rotation angle measured by the rotation measuring portion reaches the upper limit of the range input in advance (for example, the position from the reference 0° to +45°), the operation member 9 and the grasping operation member are substantially maintained. 7 While holding the operation site, the sputum is moved to the side in the width direction by the manipulation member 9 and the grasping operation member 7 (for example, moving toward the neck).

When the rotation angle measured by the rotation measuring unit reaches the upper limit of the range input in advance (for example, +45°), the command is transmitted from the control unit to the drive motor 15, and the rotation is performed in the manner shown in FIG. 14(B). The direction of rotation of the shaft 10 is switched from forward to reverse. Then, before the rotation angle measured by the rotation measuring portion reaches the lower limit of the range input in advance (for example, the position from the reference 0° to -45°), the operation member 9 and the grasping operation member 7 are substantially maintained. The state of the operation site is moved so that the sputum 9 and the grasping operation member 7 move in the width direction to the other side (moving away from the neck).

Thereafter, the control unit transmits a command to the push drive motor 15, and the rotation direction of the rotary shaft 10 is subsequently switched from reverse rotation to forward rotation in the manner shown in FIG. 14(A).

[Fifth Embodiment]

Next, the massage device 1 according to the fifth embodiment will be described.

The massage device 1 of the fifth embodiment has a mechanism (massage mechanism) substantially the same as that of the first embodiment shown in FIG. 4 and the like.

However, the massage device 1 of the fifth embodiment differs from the massage device of the first embodiment in that, as shown in Fig. 15, the massaging device 1 of the fifth embodiment is located closest to the applicator member in the grasping operation member 7. In the state of 9, in other words, when the operation site is pushed into the state between the application member 9 and the grasping operation member 7, the massage member 2 and the grasping massage member 8 are advanced and retracted while grasping the operation site. (Alternately reciprocating in the forward direction and the backward direction), a more effective massage is applied to the site of operation (hereinafter referred to as "grasping massage").

Specifically, in the massaging apparatus 1 of the fifth embodiment, the striking drive shaft 21 is continuously rotated in one direction to the reverse direction, and the gripping and urging member 9 and the urging member 7 are reciprocated in a small pitch.

For example, as shown in FIG. 15, in the state in which the grasping operation member 7 is closest to the operation member 9 (the state in which the operation portion is grasped by the grasping operation member 7 and the operation member 9 is grasped), the rotation axis 10 is considered. In a state where the rotation is stopped, only the hammer drive shaft 21 is continuously rotated in one direction.

Since the rear end side of the crank arm 20 is eccentrically rotated with respect to the axis of the hammer drive shaft 21, the rotation direction of the hammer drive shaft 21 is in either the forward direction or the reverse direction. When the hammer drive shaft 21 is continuously rotated, the front end of the crank arm 20 reciprocates in the front-rear direction (in the case of FIG. 15 in the up-and-down direction). Then, the link The position of the massage member 2 on the front end side of the crank arm 20 can be moved up and down, so that the clicker 9 and the grasping and applying member 7 provided on the massage member 2 advance and retreat around the rotary shaft 10 in the front-rear direction.

According to this configuration, the operation site can be pushed forward in the state between the grasping operation member 7 and the operation member 9 at the operation site, and sometimes the state is moved toward the operation site. Rear (grab the push massage). Similar to the above-mentioned small-pitch gripping massage, this kind of massage is very beneficial in terms of further improving the blood flow effect on the severely rigid operation site.

In addition, the grasping operation member 9 or the urging member 7 together with the massaging device 1 described above can be reciprocally moved in the front-rear direction with respect to the base member 4 for a short time instead of rotating the slamming drive shaft 21 as described above. The grasping operation member 9 and the cymbal member 7 are configured to reciprocate forward and backward for a short period of time.

In the description of the massaging mechanism (grasping and urging mechanism) of the fifth embodiment, only the slamming drive shaft 21 is continuously rotated while the rotating shaft 10 is stopped, but the rotating shaft 10 may not be stopped. In the fourth embodiment, the rotation direction of the rotary shaft 10 is alternately switched to the positive direction and the reverse direction every rotation angle of less than one rotation, and only the hammer drive shaft 21 is continuously rotated. The short-distance interval grasping massage is continuously performed on the operation site between the surgical device 9 and the grasping operation member 7.

In this case, both the "pinch massage" described in the fourth embodiment and the "push massage" described in the fifth embodiment are applied to the operation site, so that an effective massage can be performed.

In addition, the embodiments disclosed herein are to be considered in all respects In particular, in the embodiments disclosed herein, the items disclosed are not understood, for example, operating conditions or operating conditions, various parameters, size, weight, volume, etc. of the components are not exceeded by those generally practiced by the industry. As long as it is common in the industry, it is easy to think of the value.
