[0002] In clinical practice, postoperative upper limb patients require joint range of motion training to promote rehabilitation. Traditional methods of upper limb postoperative joint range of motion training have many limitations. On the one hand, some training methods rely on the patient's independent movement, but due to the limited limb strength and mobility of postoperative patients, it is difficult to ensure the standardization and effectiveness of the training, which may lead to poor training results and affect the rehabilitation process. On the other hand, some simple auxiliary training devices have limited functions and cannot be flexibly adjusted according to different rehabilitation stages and individual differences of patients, making it difficult to meet diverse training needs. Moreover, when training the range of motion of joints, it is not possible to adjust the size of the joint range of motion, and it cannot provide patients with precise and personalized training programs. Therefore, we propose an upper limb postoperative joint range of motion training device to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 An upper limb postoperative joint mobility training device includes a base plate 1, which serves as a basic support structure. Two fixed plates 9 are welded to the top surface of the base plate 1. The two fixed plates 9 are rotatably connected to a movable plate 4 on the side close to each other via a rotating shaft. The movable plate 4 can rotate around the rotating shaft at a certain angle.

[0020] A support base 8 is welded to one side of the top surface of the base plate 1. An mounting plate 11 is fixedly installed on the top surface of the support base 8. The drive motor 10 is fixedly installed on the top surface of the mounting plate 11 by bolts. A rotating plate 6 is installed at the output end of the drive motor 10. A groove is opened on the side of the rotating plate 6 away from the drive motor 10.

[0021] A groove matching the first sliding block 13 is opened on the left side wall of the movable plate 4. The first sliding block 13 has a T-shaped cross section, which allows it to slide stably in the groove. A trapezoidal screw 12 is rotatably connected to the inner wall of one side of the groove of the rotating plate 6, passing through the second sliding block 14 and extending to the outside of the rotating plate 6. A threaded hole matching the outer thread of the trapezoidal screw 12 is opened on the second sliding block 14. The second sliding block 14 is threadedly connected to the trapezoidal screw 12 through the threaded hole, and can slide along the groove when the trapezoidal screw 12 rotates. A handwheel 15 is installed at the end of the trapezoidal screw 12 located outside the rotating plate 6 for easy manual rotation of the trapezoidal screw 12.

[0022] A rotating shaft 16 is installed on one side of the second sliding block 14. A mounting hole for the rotating shaft 16 is opened on the side of the first sliding block 13 close to the second sliding block 14, and the first sliding block 13 is installed in the mounting hole opened in the second sliding block 14 through a bearing, so as to realize the rotational connection between the first sliding block 13 and the second sliding block 14.

[0023] Both sides of the movable plate 4 are fitted with tension straps 5 on the upper and lower parts. The tension straps 5 are equipped with Velcro to fix the patient's upper limb, such as the forearm of the affected limb, into the placement slot of the protective plate 3 installed on the movable plate 4. The placement plate 2 is fixedly installed on one side of the top surface of the base plate 1, so that the upper arm of the affected limb can be placed in the placement slot at the top of the placement plate 2. Both the placement plate 2 and the protective plate 3 are filled with sponge pads or latex pads to provide comfortable support and protection for the patient.

[0024] In use, the patient places the forearm of the upper limb in the placement slot of the protective plate 3 and fixes it with the tightening strap 5 set on the movable plate 4. Since the tightening strap 5 is equipped with Velcro, it is easy to fix the forearm of the upper limb. Then, the drive motor 10 can be started to drive the rotating plate 6 to rotate. In turn, the second sliding block 14 can drive the first sliding block 13 to perform flexion and extension reciprocating motion in the sliding groove opened on the left side of the movable plate 4. This can further drive the movable plate 4 to perform flexion and extension reciprocating motion, thereby achieving the purpose of training the joint range of motion of the patient's upper limb after surgery.

[0025] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment is similar in overall structure to Embodiment 1, but some details have been optimized. A protective shell 7 is installed on the top of the support base 8 by bolts, and the drive motor 10 is placed inside the protective shell 7. Heat dissipation holes are opened on the protective shell 7, which can protect the drive motor 10 from the influence of the external environment and ensure its heat dissipation needs.

[0026] The inner wall of the sliding groove of the movable plate 4 is smoothed to reduce the friction when the first sliding block 13 slides, making the sliding smoother. At the same time, the trapezoidal lead screw 12 is surface hardened to improve its wear resistance and service life.

[0027] In actual use, after the patient fixes the forearm of the upper limb on the movable plate 4, medical staff can adjust the rotation of the trapezoidal screw 12 precisely through the handwheel 15 according to the patient's recovery status, control the sliding distance of the second sliding block 14, thereby adjusting the rotation angle and speed of the movable plate 4. Then the drive motor 10 can be started, the rotating plate 6 starts to rotate, and can provide the patient with more precise training.

[0028] Example 3: Please refer to Figure 1 , Figure 2 and Figure 3 Based on the above embodiments, this embodiment further improves the comfort and safety of the device. The soft pads filled in the placement plate 2 and the protective plate 3 are replaced with latex soft pads. Latex soft pads have better elasticity and breathability, can better fit the patient's body, and provide more comfortable support.

[0029] The compression band 5 is made of soft, elastic fabric, with an additional layer of skin-friendly cotton on the part that comes into contact with the patient's skin to reduce irritation. At the same time, anti-slip pads are added to the Velcro fasteners of the compression band 5 to prevent it from loosening during use.

[0030] During the use of the device, the patient fixes the upper limb, such as the forearm of the affected limb, on the movable plate 4. The latex pad and soft strap 5 provide a comfortable experience. The drive motor 10 drives the rotating plate 6 to rotate. The rotation of the movable plate 4 is achieved by adjusting the trapezoidal screw 12, which assists the patient in training. The anti-slip pads ensure that the strap 5 firmly fixes the patient's upper limb, improving the safety of training.

[0031] Implementation effect: By placing the patient's upper limb forearm in the placement slot of the protective plate 3 and fixing it with the tightening strap 5 set on the movable plate 4, the patient's upper limb forearm can be easily fixed by the Velcro on the tightening strap 5. Then, the drive motor 10 can be started to drive the rotating plate 6 to rotate, which in turn drives the first sliding block 13 to reciprocate in the sliding groove opened on the left side of the movable plate 4 through the second sliding block 14. This further drives the movable plate 4 to perform flexion and extension reciprocating movements, thereby achieving the purpose of training the range of motion of the patient's upper limb joints after surgery.

[0032] After fixing the patient's forearm to the movable plate 4, medical staff can precisely adjust the rotation of the trapezoidal screw 12 through the handwheel 15 according to the patient's recovery status, control the sliding distance of the second sliding block 14, and thus adjust the rotation angle and speed of the movable plate 4. Then, the drive motor 10 can be started, the rotating plate 6 starts to rotate, and the movable plate 4 can be driven to perform flexion and extension reciprocating movements through the first sliding block 13 and the second sliding block 14, which can provide the patient with more precise training.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
