FIG. 1 and FIG. 2 show a schematic view of the overall structure of a tissue regulating device provided by an embodiment of the present invention, and FIG. 3 shows an exploded schematic view of the tissue regulating device.

Please refer to FIG. 1 to FIG. 3 , the tissue adjustment device includes a base 1000 , a first connecting mechanism 2000 , a second connecting mechanism 3000 , a first driving part 4000 and a second driving part 5000 . The first connection mechanism 2000 is connected to the base 1000, and the second connection mechanism 3000 forms an angle with the first connection mechanism 2000. For example, before actual use, the angle of the angle can be is 180°. The second connection mechanism 3000 is also configured to be able to rotate around a rotation axis, and to change the angle formed by the second connection mechanism 3000 and the first connection mechanism 2000 . The first driving part 4000 is disposed on the base 1000 and connected with the second connecting mechanism 3000, and is configured to drive the second connecting mechanism 3000 around the The axis of rotation rotates in a first direction. The second driving part 5000 is connected to the base 1000 and also connected to the second connecting mechanism 3000 . The second driving part 5000 is configured to drive the second connection mechanism 3000 to rotate around the rotation axis in a second direction under the action of a second external force, and the second direction is opposite to the first direction. Those skilled in the art can understand that when the first direction is clockwise, the second direction is counterclockwise, and vice versa.

The tissue adjustment device is used for rehabilitation training of stiff joints, and the joints may be knee joints, elbow joints, wrist joints, ankle joints, etc. For the convenience of presentation, this article takes the rehabilitation training of the knee joint by using the tissue adjustment device as an example, but those skilled in the art can modify the following description to make it applicable to the rehabilitation training of other joints.

The first connecting mechanism 2000 is used for connecting with the patient's thigh, and the second connecting mechanism 3000 is used for connecting with the patient's calf. During actual manufacture, there may be a certain difference in size between the first connecting mechanism 2000 and the second connecting mechanism 3000 , and usually the first connecting mechanism 2000 remains relatively stationary relative to the base 1000 , so The first connection mechanism 2000 and the second connection mechanism 3000 are easy to distinguish, so the tissue adjustment device is easy to wear and less prone to mistakes.

When the first driving part 4000 drives the second connecting mechanism 3000 to rotate along the first direction, the second connecting mechanism 3000 can drive the patient's calf to rotate along the first direction to perform stretching or flexion movement. It should be noted that if the first driving part 4000 drives the patient's calf to do stretching, then the first driving part 4000 cannot drive the patient's calf to do flexion; on the contrary, if the first driving part 4000 drives the patient If the calf of the patient is flexed, the patient's calf cannot be driven to stretch, that is, the first driving part 4000 can only drive the patient's calf to do either stretching or flexing. In the following, the first drive unit 4000 is used as an example to drive the patient's calf to perform stretching exercises. Likewise, when the second driving part 5000 drives the second connecting mechanism 3000 to rotate along the second direction, the second connecting mechanism 3000 can drive the lower leg of the patient to rotate along the second direction. Since the second direction is opposite to the first direction, when the first driving part 4000 drives the second connecting mechanism 3000 to rotate and drives the patient's calf to do stretching, the second driving part 5000 is The second connecting mechanism 3000 is driven to rotate to drive the patient's calf to do flexion. That is to say, the tissue adjustment device provided in this embodiment can independently perform extension and flexion training for the patient. The advantage of such setting is that after wearing the tissue adjustment device, the patient can directly perform another kind of exercise training (such as flexion training) after one kind of exercise training (such as stretching training), without repeatedly putting on and taking off the tissue adjustment device. Tissue adjustment device to improve training efficiency.

Preferably, the tissue adjustment device further includes a locking member, the locking member is used to lock the second connecting mechanism 3000 on the base 1000 and prevent the second connecting mechanism 3000 from rotating around the Axis rotation. When the tissue adjustment device is in use, firstly adjust the angle between the second connecting mechanism 3000 and the first connecting mechanism 2000 according to the stiffness of the patient's knee joint, and then use the locking member to lock the The above-mentioned second connection mechanism 3000 is locked, so that the angle of the included angle can be maintained, which is convenient for wearing. In an optional implementation, the locking member includes a screw and a locking screw hole 3001 provided on the second connecting mechanism 3000. When the screw is screwed into the locking screw hole 3001, it is pressed against When on the base 1000, the second connection mechanism 3000 is locked against rotation around the axis of rotation.

Not only that, the tissue adjustment device is also configured such that when the locking member locks the second connecting mechanism 3000 on the base 1000 and the first driving part 4000 is subjected to the first external force, When functioning, at least part of the structure of the first driving part 4000 undergoes elastic deformation and stores elastic potential energy (that is, at least part of the structure of the first driving part 4000 converts the first external force into elastic potential energy through deformation and stores it) . When the locking member locks the second connecting mechanism 3000, the first driving part 4000 releases the elastic potential energy and drives the second connecting mechanism 3000 to rotate along the first direction. It is set in this way, so that the first driving part 4000 can store the first external force (as mentioned above, the first external force is converted into elastic potential energy and then stored), and then release it slowly without going all the way to the first driving part. 4000 applying the first external force.

Similarly, when the locking member locks the second connecting mechanism 3000 on the base 1000 and the second driving part 5000 is subjected to the second external force, the second driving part 5000 At least part of the structure is elastically deformed and stores elastic potential energy. When the locking member releases the locking of the second connecting mechanism 3000, the second driving part 5000 releases the elastic potential energy and drives the second connecting mechanism 3000 along the The second direction rotates.

In other words, the tissue regulating device provided in this embodiment has two usage modes, which are referred to as the first mode and the second mode here respectively. In the first mode, after the patient finishes wearing the tissue adjustment device, he continuously applies a corresponding external force to any driving part, for example, continuously applies the first external force to the first driving part 4000 to perform corresponding Sports training such as stretching exercises. When the movement needs to be switched, the patient can continuously apply the second external force to the second driving part 5000 to perform flexion training. In the second mode, the patient can lock the second connecting mechanism 3000 with the locking member after wearing the tissue regulating device, so as to temporarily prevent the second connecting mechanism 3000 from rotating. Then apply the first external force to any driving part, such as the first driving part 4000, so that the first driving part 4000 is at least partially deformed and stores elastic potential energy. Then stop applying the first external force, and release the locking of the second connecting mechanism 3000 by the locking member, and then the first driving part 4000 can automatically drive the second connecting mechanism 3000 along the first The direction is rotated, and the patient is driven to carry out corresponding exercise training. The patient can use the second mode for rehabilitation training during sleep time, so that the patient does not need to reserve special time for rehabilitation training, making the use of the tissue adjustment device more convenient and flexible.

In addition, it should be noted that, the first external force and the second external force are distinguished according to the direction of rotation of the driven second connecting mechanism 3000, and the length of application time and the magnitude of the force irrelevant.
