Description

Myofascial Adhesion Rehabilitation Device

The invention relates to a rehabilitation device, in particular to a myofascial adhesion rehabilitation device.

Myofascia is a kind of elastic connective tissue, which is distributed under the human skin, from superficial to deep, between human muscle, subcutaneous fat and epidermis. Myofascia is like the body's built-in tights. If you want to move freely, myofascia needs to be able to stretch freely, and the different layers of myofascia need to be able to slide smoothly against each other.

When the human body is traumatized or undergoes surgery, resulting in wounds, fibroblasts are stimulated to produce collagen to rebuild the damaged area. When the wound is large, collagen will proliferate rapidly to speed up the healing of the wound, but such random and rapid proliferation will make the texture, direction, and layer of the newly formed tissue different from the original skin, resulting in scarring.

In addition, the chaotic hyperplastic tissue will destroy the layers between the original myofascia, causing the myofascia to stick to each other, hindering the stretching of the myofascia and the sliding between each other. Since myofascia is distributed between human muscles, subcutaneous fat, and epidermis, when the myofascia in one place is abnormal, the tension formed will be transmitted to other adjacent parts of the body, restricting the body's stretching and bending, and In order to resist the pulling force, the body may produce bad movements, and symptoms such as fatigue, tension, and soreness may appear one after another over time.

The shaft portion 21 is disposed between the first limiting slot 111 a and the second limiting slot 121 a, and is pivotally connected to the third connecting rod 44 . The washboard part 22 is suitable for setting an artificial skin and massaging scars on the human body.

Referring to Fig. 2, Fig. 5 to Fig. 7, specifically, when the drive unit 3 operates, the worm 33 of the drive unit 3 will drive the worm wheel 41 of the transmission unit 4, so that the worm wheel 41 will simultaneously drive the first chain The rod 42, the second connecting rod group 43, the third connecting rod 44, and the kneading rod 2 actuate. Wherein, the first connecting rod 42 rotates back and forth with the worm wheel 41 as the fulcrum, the second connecting rod group 43 rotates back and forth with the center pin 64 as the center, and the third connecting rod 44 and the kneading rod 2 are due to the The shaft part 21 of the kneading rod 2 is limited by the first limiting groove 111a and the second limiting groove 121a, so that the third connecting rod 44 and the kneading rod 2 can only reciprocate in the front-rear direction D1 . Since the rubbing rod 2 can move back and forth in the front and rear direction D1, the patient can operate the adhesion rehabilitation device to press the rubbing part 22 of the rubbing rod 2 on the scar, and the front and rear of the rubbing rod 2 Move back and forth to achieve the effect of massaging the scars, and then loosen and flatten the myofascia that sticks to each other, so as to solve the problems of tightness, soreness, and limited movement caused by the scars on the body of patients in daily life or sports. And solve the problem of hand soreness easily caused by long-term freehand massage.

In addition, by rotating the adjusting screw 62, the middle pin 64 is driven to move up and down, and the distance between the middle pin 64 and the pivot joints of the second connecting rod and the third connecting rod 44 is adjusted, so that the middle pin 64 can be changed. Knead the stroke that bar 2 moves back and forth. Specifically, when the adjusting screw 62 rotates clockwise, the nut in the mounting seat 61 will rise, and then drive the middle pin 64 to rise, reducing the connection between the middle pin 64 and the second connecting rod and the third connecting rod 44. The distance between the pivot joints reduces the stroke of the third connecting rod 44 and the kneading rod 2 moving back and forth. Conversely, when the adjusting screw 62 rotates counterclockwise, the nut in the mounting seat 61 descends, driving the intermediate pin 64 to descend, increasing the pivotal distance between the intermediate pin 64 and the second connecting rod and the third connecting rod 44. The distance between the third connecting rod 44 and the kneading rod 2 increases the stroke of reciprocating movement back and forth. With the above functions, the adhesive rehabilitation device can be applied to scars of different sizes and lengths, and provide different massage strokes.

In a modified implementation, the sticking rehabilitation device can also be equipped with a support (not shown in the figure), and the sticking rehabilitation device can move up and down along the support and rotate 360 degrees so that the patient does not need to hold the sticky Rehabilitation device, the sticky rehabilitation device can be moved to the scar for massage.

To sum up, the myofascial adhesion rehabilitation device of the present invention can achieve the effect of massaging scars by the reciprocating movement of the rubbing rod 2 in the front-back direction D1, thereby allowing the myofascial adhesions to be loosened, Leveling, solving the problems of tightness, soreness, and limited movement caused by scars on the body of patients in daily life or sports, and solving the problem of hand soreness easily caused by long-term freehand massage, so it can really achieve the goal of the present invention. Purpose.
