Description

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a limb fracture recovery exercise device. Background Art

[0002] Rehabilitation exercises play a pivotal role in the treatment of wrist and elbow injuries (such as fractures or ligament tears). These joints are important hubs for upper limb activity, and the restoration of their functions directly affects the patient's daily quality of life and work ability. After surgical treatment, pain and fear of activity can lead to muscle adhesion, atrophy, joint stiffness, and loss of mobility. To avoid this, proper rehabilitation training is key. For example, grip training, wrist and elbow joint function training, and other exercises can effectively restore the strength of various upper limb muscle groups, reduce joint adhesion, and gradually restore joint function.

At this time, the spring 135 is compressed, and the entire device is clamped on the desktop through the clamping head 132;

[0033] In addition, in this embodiment, in order to adapt to the clamping of an imperfectly flat surface, the diameter of the upper end of the push rod 134 is designed to be smaller than the diameter of the row of holes 13. Through the small diameter design of the push rod 134, when the threaded rod 131 is pushed forward, if it is an imperfectly flat plane, the push rod 134 will swing left and right until it fits on the surface of the clamped object to adapt to the clamping of the imperfectly flat surface. In addition, circular protrusions 133 are symmetrically fixed on both sides of the lower end of the clamping head 132; the circular protrusions 133 can be clamped into the concave and convex parts of the imperfect plane to form a better clamping.

In this embodiment, the method of controlling the rotation angle of the contact plate by controlling the angle of the motor is achievable in the prior art, and can be achieved by stepping motor and PLC control, which will not be explained in detail here.

Since the area of ​​the square groove 321 gradually increases outwardly along the axial direction, when the vertical plate 34 is installed, it will tilt to both sides. Since it tilts outwardly during exercise, the angle fixing requirement of the interface is achieved after the arm is placed, and the arm is fixed by the fixing belt 33 at the same time.

[0037] Example 4

[0038] In this embodiment, the palm exercise component 41 can be used to train the wrist joint in flexion, extension, and ulnar deviation.

[0039] Example 5

[0040] In this embodiment, the patient's fingers are trained through the finger training component 42, and through the flexion and extension activities of the fingers, such as extending the fingers and making a fist, the muscles of the forearm and hand can be effectively trained to prevent their atrophy; specifically, the finger training component 42 includes: a fixed base 421, a weight 4231, an inclined plate 424, and an adjustment rod 425; a plurality of finger training grooves are opened on one side of the upper end of the fixed base 421, and a weight placement groove 423 is opened on the other side of the upper end, and a plurality of weights 4231 are placed linearly on the weight placement groove 423; a plurality of adjustment holes are set at the positions corresponding to the weight placement grooves 423 on the rear side of the fixed base 421; when in use, the adjustment rod 425 is inserted into the positions on different adjustment holes according to the weight to be exercised to adjust the strength, and the fingers can be exercised separately according to the actual situation of the fingers. When exercising, each finger can be set with a weight separately, and the principle of the method of inserting the adjustment rod 425 is similar to the principle of adjusting the center of gym exercise equipment.

[0041] In addition, in the present embodiment, an inclined plate 424 is provided between the finger exercise groove and the weight placement groove 423, an arc-shaped slide groove 4241 is provided at the upper end of the inclined plate 424, a pull wire 4242 is provided on the arc-shaped slide groove 4241, one end of the pull wire 4242 is fixedly connected to the weight 4231, and the other end extends to the finger exercise groove, and a pull ring 4243 is fixedly provided; the number of weights 4231 is adjusted by adjusting the position of the adjusting rod 425 on the adjusting hole to adjust the strength of the finger exercise; and the inclined plate 424 is tilted and the angle formed with the fixed base 421 along the counterclockwise direction is between 0° and 90°, and the pull ring 4243 is put on the patient's finger for Finger exercise, at the same time, the angle of the inclined board 424 will affect the weight that the patient's fingers bear during exercise. When the angle is 60°, the force exerted on the fingers is / (gravity of the weight block / cos(90°-60°)). Assuming that the weight of the weight block 4231 is 50N, the weight pulled up by the fingers must be 57.73N, which changes continuously according to the angle. When it is 30°, the weight is 100N, and when it is 45 degrees, the time is 70.72°. Therefore, when the angle is 60°, it is the best angle, and its weight is close to the weight of the weight block 4231. The user knows approximately how much weight he or she is exercising, and can choose according to the quality suitable for finger exercise.

[0042] The use principle of the present invention is as follows: when it is necessary to exercise the wrist, the arm can be fixed by the fixing belt 33, and the vertical plate 34 can be removed and the palm can be fixed by the restraining belt 415. After fixing, the angle of the ulnar deviation needs to be selected and determined, and then the angle limiting rod 414 is inserted into the corresponding slot 413, and then the motor is started to exercise the wrist. At the same time, the position of the angle limiting rod 414 can be gradually adjusted according to the exercise angle. When the travel switch 4111 touches the limiting rod, the motor immediately turns to perform reverse exercise; when it is necessary to exercise the elbow, the angle limiting rod 414 is inserted into the corresponding slot 413, and then the motor is started to exercise the wrist. The palm is fixed by the restraint belt 415, and the vertical plate 34 is inserted at the same time. When inserting, the corresponding square slot 321 is selected according to the needs, and then the arm is fixed by the fixing belt 33, and then the motor is started to perform flexion and extension exercises on the elbow; at the same time, when it is necessary to exercise the fingers, the finger exercise component 42 is inserted and fixed, and after being fixed, the exercise weight is adjusted by the limit rod according to the actual needs, and then the pull ring 4243 is put on the finger to perform active flexion and extension exercises; after the exercise is completed, the fixing belt 33 and the restraint belt 415 are untied to remove the arm;

[0043] Before exercising, if exercising on a desktop, the entire device can be directly placed. When it needs to be clamped on a flat surface or a plane that is not completely flat, the entire device can be clamped by the clampable base 1 and then fixed.
