[0002] In the field of rehabilitation medicine, there is an increasing demand for functional recovery and strength enhancement of the upper limbs, especially the elbow to hand area. Traditional rehabilitation training methods usually rely on single-function equipment or manual operations, which not only limits the diversity and efficiency of training, but also makes it difficult to meet the personalized rehabilitation needs of different patients.

[0003] Most existing rehabilitation equipment focuses on training a certain part or a certain type of movement, such as strength training limited to the wrist or flexibility exercises for the fingers. This single-function design cannot meet the complex and diverse rehabilitation needs. Since the rehabilitation progress and needs of each patient are different, fixed-design rehabilitation equipment is difficult to flexibly adjust according to individual differences, thus affecting the rehabilitation effect. Traditional rehabilitation equipment is often bulky, difficult to move, and requires a large space to be placed, which poses a challenge to the effective use of medical institution resources. Summary of the invention

[0004] The present application aims to at least solve one of the technical problems that existing rehabilitation devices in the prior art are mostly focused on a certain part or a certain type of movement training, such as limited to wrist strength training or finger flexibility training, and such a single-function design cannot meet the complex and diverse rehabilitation needs. To this end, the present application proposes a postoperative limb exercise device.

[0028] A postoperative limb exercise device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 9 As shown, a postoperative limb exercise device according to an embodiment of the present application includes a base 1, a platform 2 is rotatably provided on the upper end of the base 1, an arc groove 3 is opened on the upper side of the platform 2, the arc groove 3 is used for placing the arm to support the arm, and the inner shell of the arc groove 3 is padded to ensure the comfort of the patient.

[0030] At the same time, adjusting rods 4 are rotatably set on both sides of the platform 2, and a pair of supporting straps 5 are set inside the two groups of adjusting rods 4. A fixing strap 6 is set on the upper side of each supporting strap 5. After the arm is extended inside the supporting strap 5, it can be fixed by the fixing strap 6, so as to ensure the stability during exercise. In order to realize the lifting movement of the arm starting from the elbow joint, a rotating rod 12 is set on the inner side of the platform 2. The rotating rod 12 is firmly connected to the two adjusting rods 4 through both ends. A gear 2 13 is fixed on the rotating rod 12. At the same time, a gear 3 14 driven by a motor 15 is also provided on the inner side of the platform 2. When the motor 15 is started, the gear 3 14 and the gear 2 13 are meshed, so that the rotating rod 12 drives the adjusting rod 4 to rotate. This mechanism enables the adjusting rod 4 to lift the arm upward from the elbow joint, thereby effectively promoting the functional recovery and strength enhancement from the elbow to the hand area.

[0031] Furthermore, a rotatable rotating rod 2 16 is provided at the upper end of the base 1, and the rotating rod 2 16 is fixedly connected to one side of the platform 2. When the rotating rod 2 16 is rotated, the entire platform 2 rotates accordingly, thereby driving the arm placed thereon to perform an overall lateral rotation. This design not only increases the diversity of training, but also helps to improve the flexibility and coordination of the shoulders and upper arms. In this way, the user can perform a variety of training at different stages of rehabilitation, including overall rotation of the arm. This makes rehabilitation training no longer limited to movements in a single plane, but can be performed in multiple dimensions, thereby promoting the functional recovery of the upper limbs more comprehensively. Another advantage of this design is that it is easy to operate. The overall lateral movement of the arm can be achieved by simply rotating the rotating rod 2 16, which provides great convenience for patients and medical staff.

[0032] It is worth noting that a slide groove 1 7 is designed on the upper side of the adjustment rod 4, in which a grip training mechanism 11 is slidably installed. At the same time, a slide groove 2 71 is also provided on the inner side of the adjustment rod 4, in which a wrist training mechanism 10 is slidably installed. This layout allows the grip training mechanism 11 and the wrist training mechanism 10 to switch positions through a simple sliding operation. Specifically, the user can easily switch between grip training and wrist training according to their own rehabilitation training needs. When grip training is required, the grip training mechanism 11 is slid along the slide groove 1 7 to the appropriate position; similarly, when it is necessary to focus on strengthening the wrist strength, the wrist training mechanism 10 can be adjusted to slide along the slide groove 2 71 to the desired position. Such a design not only improves the flexibility of the equipment, but also ensures the convenience and efficiency of the training process.

[0033] The wrist training mechanism 10 includes a movable plate 101 slidably mounted in the second slide groove 71, and a wrist stand 104 is fixedly arranged on the upper side thereof. The wrist stand 104 is designed to place the wrist and is firmly fixed by the second fixing belt 105. In addition, a rotatable palm plate 106 is provided at the front end of the base 1. The palm plate 106 is equipped with a plurality of finger buckles 107. The user can insert five fingers into these finger buckles 107 respectively, and then use the third fixing belt 109 to firmly fix the palm on the palm plate 106. An air bag 108 is connected between the palm plate 106 and the movable plate 101. The air inlet end of the air bag 108 is connected to an inflatable ball 1081 through a pipeline. The inflatable ball 1081 is equipped with an air release valve. When it is necessary to perform wrist training, the user first places the wrist on the wrist stand 104 and fixes it with the second fixing belt 105, and then inserts the fingers into the finger buckles 107 on the palm plate 106 and uses the third fixing belt 109 to release the air. Three 109 fixes the palm, and then, by repeatedly squeezing the inflatable ball 1081, the airbag 108 gradually expands, thereby pushing the palm plate 106 to rotate upward, and realizing effective exercise of the wrist. After the training is completed, open the air release valve to release the air in the airbag 108, and the palm plate 106 will slowly return to its original position. This design allows the user to complete dynamic exercise of the wrist through simple operations, which not only enhances the strength and flexibility of the wrist, but also improves the safety and comfort of the training process. At the same time, by adjusting the squeezing frequency and strength of the inflatable ball 1081, the exercise intensity can be customized according to the individual's specific rehabilitation needs to ensure that each user can get the rehabilitation experience that suits him or her best.

[0034] According to the specific needs of the patient, the wrist training mechanism 10 can slide outward to make room for the grip training mechanism 11 to move to a position close to the patient's hand for grip training. The grip training mechanism 11 includes a slide rail 111 slidably installed in a slide groove 7, and a grip shell 113 is further slidably arranged on the slide rail 111. A plurality of groups of springs 2 115 are arranged inside the grip shell 113, and the upper ends of these springs are connected to another grip shell - grip shell 2 114. During use, the patient's hand holds grip shell 1 13 and grip shell 2 114, and presses grip shell 2 114 downward to cause spring 2 115 to produce elastic deformation. By repeatedly squeezing and releasing grip shell 2 114 and utilizing the elastic expansion and contraction characteristics of spring 2 115, the grip strength can be effectively trained. This design can not only enhance the grip strength of the hand, but also promote the strength development and flexibility improvement of the wrist area.

[0035] Furthermore, a spring 112 is provided inside the slide rail 111, and the upper end of the spring is connected to the side of the grip shell 113. Through the pushing action of the spring 112, the grip shell 113 and the connected grip shell 2 114 can be maintained at a higher position. This design ensures that the grip shell 113 and the grip shell 2 114 will not hinder the position switching between the grip training mechanism 11 and the wrist training mechanism 10, thereby ensuring the smoothness and flexibility of the use of the equipment. Specifically, when grip training is not required, the spring 112 can automatically push the grip shell 113 and the grip shell 2 114 to a higher default position to prevent them from obstructing the operation of other components. When grip training is required, the patient only needs to extend his hand between the grip shell 113 and the grip shell 2 114, and apply pressure to make the grip shell 2 114 compress the spring 2 115 downward to start the training process. After the training is completed, the pressure is released, and the grip shell 1 113 and the grip shell 2 114 will return to a higher position under the action of the spring 1 112, ready for the next use or position adjustment.

[0036] In order to facilitate the replacement and adjustment of the grip exercise mechanism 11 and the wrist exercise mechanism 10, a rack 116 is set at the bottom of the slide rail 111, and a rack 2 102 is set on one side of the movable plate 101. A gear 19 is rotatably set on one side of the adjustment rod 4, and the two sides of the gear are respectively engaged with the rack 116 and the rack 2 102. Therefore, by rotating the gear 19, the rack 116 and the rack 2 102 can be driven to move relative to each other, thereby realizing the position switching of the grip exercise mechanism 11 and the wrist exercise mechanism 10. It is worth noting that the height of the grip exercise mechanism 11 is designed to be higher than that of the wrist exercise mechanism 10 to ensure that there is no interference between the two.

[0037] In addition, in order to increase the stability and smoothness of the moving plate 101 during movement, rollers 103 are rotatably arranged on the lower side of the moving plate 101. These rollers 103 roll in the slide grooves 8 provided on the adjusting rod 4, so that the moving plate 101 can slide more steadily and smoothly when adjusting its position. This design not only simplifies the conversion process between different exercise mechanisms, but also improves the overall operational convenience and user experience of the equipment. Through such a mechanical layout, users can quickly and easily adjust to the most suitable training mode according to their own rehabilitation needs, which greatly improves the flexibility and efficiency of rehabilitation training.

[0038] In summary: place the patient's arm in the arc groove 3 on the platform 2, use the support belt 5 in the adjustment rod 4 to support the arm, and fix it firmly with the fixing belt 1 6, start the motor 15, drive the gear 3 14 to rotate, and the gear 2 13 engaged with it rotates accordingly, driving the rotating rod 1 12 and the adjusting rod 4 to rotate, and the rotation of the adjusting rod 4 causes the arm to be lifted upward from the elbow joint, and dynamic movement is performed to promote functional recovery and strength enhancement from the elbow to the hand area, and the rotating rod 2 16 is rotated to make the entire platform 2 and the arm thereon rotate left and right, which helps to improve the flexibility and coordination of the shoulder and upper arm, place the wrist on the wrist platform 104 of the wrist exercise mechanism 10, and fix it with the fixing belt 2 105, insert the fingers into the finger buckle 107 on the palm plate 106, and use the fixing belt 3 109 to fix the palm, and then The inflatable ball 1081 is squeezed repeatedly to expand the airbag 108, which pushes the palm plate 106 to rotate upward to achieve effective wrist exercise. After the training, the air in the airbag 108 is released through the deflation valve to reset the palm plate 106. The position of the grip training mechanism 11 is adjusted as needed to make it close to the patient's hand. The patient holds the grip shell 1 13 and the grip shell 2 114 with his hand, and presses the grip shell 2 114 downward to make the spring 2 115 produce elastic deformation, and repeatedly perform grip training. When it is necessary to replace or adjust the grip training mechanism 11 and the wrist training mechanism 10, the position switching is quickly completed by rotating the gear 1 9 and using the rack 1 116 and the rack 2 102 to move relative to each other. The roller 103 set on the lower side of the movable plate 101 rolls in the slide groove 3 8 to ensure the stability and smoothness of the moving process.
