[0027] The present invention will be further described below with reference to the embodiments.

[0028] See also Figure 1-6 The present invention provides a forearm rotation rehabilitation device, comprising a main fixing plate 1, to which a fixing frame slide 2 and a fixing ring 3 are detachably connected, the fixing frame slide 2 comprising two mutually parallel slide rails 21, each of which is provided with a slide groove 22, a threaded pin 23 being provided in each of the slide grooves 22, the bottom ends of the threaded pins 23 being fixedly embedded in the main fixing plate 1, a butterfly nut 24 being threadedly connected to the outer side of the threaded pin 23 and located above the slide rail 21, a first curved plate 25 being fixedly connected between two adjacent ends of the slide rail 21, and a second curved plate 26 being fixedly connected between the other two adjacent ends of the slide rail 21;

[0029] Specifically, by loosening the butterfly nut 24, the distance between the elbow fixing support 4 and the forearm fixing support 6 can be adjusted. After re-tightening, it is suitable for patients of different body shapes. It is worth noting that the height of the first curved plate 25 is greater than the height of the second curved plate 26, so that the elbow fixing support 4 can maintain a suitable inclination angle.

[0030] Furthermore, the fixing ring 3 is in a "C"-shaped structure, and both ends of the fixing ring 3 are fixedly connected to positioning plates 31, and the positioning plates 31 are screwed to the main fixing plate 1;

[0031] Specifically, the "C"-shaped structure provides a stable frame, so that the fixed ring 3 is not easily deformed or displaced when subjected to force, thereby ensuring the structural stability of the entire rehabilitation device. The fixed ring 3 of the "C"-shaped structure defines the central axis of rotation, so that the forearm rotating bracket 5 can rotate smoothly around this central axis to realize the rotational movement of the forearm.

[0032] Furthermore, the angle between the main fixing plate 1 and the fixing ring 3 is in the range of 45°-60°;

[0033] Specifically, an appropriate suspension angle can reduce the burden on the patient's muscles and joints, avoiding additional pain or injury during the rehabilitation process.

[0034] Furthermore, an elbow fixing bracket 4 is mounted on the fixed frame slide 2, and the two ends of the bottom side of the elbow fixing bracket 4 are fixedly connected to the first curved plate 25 and the second curved plate 26 respectively. An elbow profiling groove 41 is provided on the upper side of the elbow fixing bracket 4, and an elbow bracket 42 is fixedly connected to the bottom of the elbow profiling groove 41. Both sides of the elbow fixing bracket 4 are fixedly connected to a first binding belt 43, and one end of the first binding belt 43 is fixedly connected to a first binding buckle 44;

[0035] Specifically, the patient's elbow is embedded in the elbow contoured groove 41 of the elbow fixing bracket 4, and the first binding belt 43 is connected to the first binding belt buckle 44, so that the elbow fixing bracket 4 and the elbow can be fixed.

[0036] Furthermore, a forearm rotating bracket 5 is mounted on the fixing ring 3, and the forearm rotating bracket 5 can slide along the track of the fixing ring 3. The forearm rotating bracket 5 includes two sliding rings 51 sleeved on the outside of the fixing ring 3, an elastic clip 52 is fixedly connected between the two sliding rings 51, and two adjacent sides of the elastic clip 52 are fixedly connected to a threaded cylinder 53, and a double-headed screw 54 is threadedly connected between the two threaded cylinders 53. A screw sleeve 55 is fixedly provided on the outer middle part of the double-headed screw 54, and a fastening bolt 56 is threadedly connected to the upper side of each sliding ring 51;

[0037] Specifically, during use, after loosening the fastening bolt 56, the patient can push the sliding ring 51 along the fixing ring 3, so that the forearm fixing support 6 drives the arm to rotate to the required treatment angle, and then retighten it to achieve the purpose of forearm rotation positioning treatment.

[0038] Furthermore, a forearm fixing bracket 6 is installed at the lower part of the forearm rotating bracket 5. The forearm fixing bracket 6 is fixedly sleeved on the inner wall of the bottom end of the elastic clip 52. A forearm profiling groove 61 is opened on the upper side of the forearm fixing bracket 6. Second binding straps 62 are fixedly connected to both sides of the forearm fixing bracket 6. One end of one of the second binding straps 62 is fixedly connected to a second binding buckle 63. An arm bracket 64 is bonded to the bottom of the forearm profiling groove 61.

[0039] Specifically, the patient's forearm is embedded in the forearm contoured groove 61 in the forearm fixing support 6, and the second binding strap 62 is bound and connected to the second strap buckle 63, so that the elbow fixing support 4 can be fixed to the forearm. It is worth noting that the forearm fixing support 6 and the elbow fixing support 4 are both made of plastic materials, which have the advantages of low production cost and low production difficulty.

[0040] Specifically, by twisting the screw sleeve 55, the screw sleeve 55 drives the double-headed screw 54 to threadably drive the two threaded cylinders 53 to approach each other, and the threaded cylinders 53 pull the two sides of the elastic clip 52 to approach each other. The elastic clip 52 can clamp the forearm fixing support 6, thereby strengthening the patient's forearm.

[0041] Working principle:

[0042] When in use, the patient's elbow is embedded in the elbow profiling groove 41 of the elbow fixing bracket 4, the first binding belt 43 is tied and connected with the first binding buckle 44, and the elbow fixing bracket 4 is fixed to the elbow. The patient's forearm is embedded in the forearm profiling groove 61 in the forearm fixing bracket 6, and the second binding belt 62 is tied and connected with the second binding buckle 63, and the elbow fixing bracket 4 is fixed to the forearm. The screwing sleeve 55 is screwed, and the screwing sleeve 55 drives the double-headed screw 54 to thread the two threaded cylinders 53 to approach each other, and the threaded cylinder 53 pulls the elastic clip 52 The two sides are close to each other, and the elastic clip 52 can clamp the forearm fixing support 6, which plays a role in strengthening the patient's forearm. After loosening the fastening bolt 56, push the sliding ring 51 along the fixing ring 3. During the sliding process of the sliding ring 51, the forearm fixing support 6 drives the arm to rotate accordingly. When it rotates to the required angle for treatment, re-tighten the fastening bolt 56 to achieve the rotational positioning treatment effect of the forearm. Loosen the butterfly nut 24 to adjust the distance between the elbow fixing support 4 and the forearm fixing support 6. After retightening, it is suitable for patients of different body shapes.
