Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment technology, and in particular to an elastic pulley rehabilitation training device for rotator cuff injuries. Background Technology

[0002] The rotator cuff is a group of tendons surrounding the shoulder joint, consisting of the subscapularis, supraspinatus, infraspinatus, and teres minor muscles. Shaped like a "cuff," it wraps around the front, top, and back of the shoulder joint. Rotator cuff injury refers to a tear or damage to these tendons, usually caused by acute trauma, chronic strain, or degenerative changes. Rehabilitation of rotator cuff injuries requires a balance between tissue repair and protection and progressive functional recovery. Pulley rehabilitation trainers are generally chosen for training. Through biomechanical optimization, pulley rehabilitation trainers have become a key tool for shoulder joint rehabilitation.

[0003] A search revealed Chinese Patent Publication No. CN205516198U, which discloses a detachable portable pulley training device. This device, consisting of a fixed base, rotating bolts, a support frame, pulleys, ropes, and a handle, can be quickly installed on the top of a door. Tightening the rope increases the distance between the handle and the ground. The trainee stands or sits under the handle, fixing their affected limb to one handle. The trainee uses their normal upper limb to pull the other handle, passively training the affected limb. During training, the trainee can perform movements such as arm abduction, extension, flexion and extension, and flexion to improve the range of motion of the shoulder and elbow joints.

[0004] In actual use, the aforementioned pulley rehabilitation training device requires the fixed base to be raised before it can be placed on the door panel. When patients with rotator cuff injuries perform overhead movements, it can aggravate tendon tears, making it impossible for them to install the pulley training device independently, thus limiting its use. Therefore, an elastic pulley rehabilitation training device for rotator cuff injuries is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an elastic pulley rehabilitation trainer for rotator cuff injuries, aiming to improve the problem that patients with rotator cuff injuries have difficulty installing the pulley rehabilitation trainer on their own in the prior art.

[0029] 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.

[0030] Reference Figures 1-2This utility model provides an embodiment of an elastic pulley rehabilitation training device for rotator cuff injuries, including a fixed frame 1. A pulley body 2 is rotatably connected inside the fixed frame 1, and the pulley body 2 can rotate inside the fixed frame 1. A pull rope 3 is wound around the outside of the pulley body 2, and the pull rope 3 is located in the gap between the pulley body 2 and the inner top surface of the fixed frame 1. The fixed frame 1 can cooperate with the pulley body 2 to limit the pull rope 3 and prevent the pull rope 3 from detaching from the fixed frame 1 during use. When the end of the pull rope 3 is pulled downward, it will move in the left and right direction, which will drive the pulley body 2 to rotate synchronously. The rotating pulley body 2 can convert the friction between itself and the pull rope 3 into rolling friction, thereby reducing friction loss. A handle 4 is fixedly connected to the end of the pull rope 3. The patient pulls the pull rope 3 through the handle 4. The patient can hold the handle with both hands, let their arms hang down, actively retract and sink their scapula to maintain scapular stability, and slowly pull the handle upward to shoulder abduction 45° for rehabilitation training.

[0031] An L-shaped mounting bracket 5 is provided above the fixed bracket 1. A rubber pad is fixedly connected to the back of the L-shaped mounting bracket 5. An elastic element 6 is fixedly connected to the inner top surface of the L-shaped mounting bracket 5. The bottom end of the elastic element 6 is fixedly connected to the upper surface of the fixed bracket 1. When the L-shaped mounting bracket 5 is limited, the fixed bracket 1 will be stretched when it is subjected to a downward pulling force, so that the elastic element 6 will be stretched and generate elastic potential energy. The generated elastic potential energy buffers and limits the downward pulling force, thereby protecting the connection with the L-shaped mounting bracket 5, reducing the risk of breakage, and preventing damage to the door panel caused by sudden force.

[0032] Reference Figures 1-2 The upper surface of the L-shaped mounting bracket 5 is fixedly connected to a connecting cloth strip 7. The connecting cloth strip 7 is flat and can be locked in the gap between the upper surface of the door panel and the door frame. The end of the connecting cloth strip 7 away from the L-shaped mounting bracket 5 is fixedly connected to a limiting rubber strip 8. After the connecting cloth strip 7 is placed on the door panel and the door panel is closed, the pull rope 3 can be pulled down to move the L-shaped mounting bracket 5 down, thereby pulling the connecting cloth strip 7 and the limiting rubber strip 8, so that the limiting rubber strip 8 can be locked at the connection between the door panel and the door frame, thereby limiting the device and allowing the trainer to be installed quickly. The bottom surface of the L-shaped mounting bracket 5 is fixedly connected to a lifting plate 9. The patient can lift the L-shaped mounting bracket 5 through the lifting plate 9 to quickly place the connecting cloth strip 7 on the door panel, thereby completing the installation of the trainer without having to excessively lift the arm.

[0033] Reference Figures 2-3A sliding plate 10 is provided on the rear side of the lifting plate 9, and a sliding unit 11 is provided on the front side of the sliding plate 10. The sliding unit 11 includes a T-shaped plate 111, which is fixedly connected to the back of the lifting plate 9. A groove 112 is provided on the front surface of the sliding plate 10. The T-shaped plate 111 is slidably connected to the groove 112. The T-shaped plate 111 can slide vertically within the groove 112. The sliding plate 10 can slide vertically with the lifting plate 9 through the cooperation of the T-shaped plate 111 and the groove 112, so that the lifting plate 9 can slide vertically relative to the sliding plate 10. A limit plate 113 is fixedly connected to the bottom surface of the T-shaped plate 111, and a suction cup 12 is fixedly connected to the back of the sliding plate 10.

[0034] After the connecting strip 7 and the limiting rubber strip 8 are positioned above the door panel, the suction cup 12 can be attached to the door panel, and the sliding plate 10 can be positioned at the desired exercise location. The lifting plate 9 can move up and down relative to the sliding plate 10 without obstructing the installation of the lifting plate 9. At the same time, the sliding plate 10 can limit the overall structure formed by the lifting plate 9, the L-shaped mounting bracket 5, and the fixing bracket 1, preventing left and right swaying, thereby preventing left and right swaying and wear between the connecting strip 7 and the door panel, and extending the service life of the connecting strip 7.

[0035] Working principle: The patient can lift the L-shaped mounting bracket 5 upwards using the lifting plate 9, which moves the connecting strip 7 and the limiting rubber strip 8 upwards to the top of the door panel. This allows the connecting strip 7 to move quickly to the top of the door panel, and the limiting rubber strip 8 to be placed on the back of the door panel. The door panel can then be closed, causing the connecting strip 7 to be wedged between the door panel and the door frame. Next, the lifting plate 9 can be pulled downwards, causing the limiting rubber strip 8 to be wedged on the back of the door panel, thus limiting the overall installation of the trainer. This completes the initial installation of the trainer. During installation, the patient does not need to excessively raise their arm and can complete the installation independently, avoiding aggravation of tendon tears. Afterwards, the suction cup 12 can be used to... The sliding plate 10 is adsorbed and limited on the door panel. The lifting plate 9 and the sliding plate 10 can slide relative to each other through the cooperation of the T-shaped plate 111 and the slide groove 112, which will not hinder the movement adjustment of the lifting plate 9. At the same time, the sliding plate 10 can limit the lifting plate 9, so that the whole structure formed by the lifting plate 9 and the fixing frame 1 will not wobble in the left and right directions, thereby reducing the wear between the connecting cloth strip 7 and the limiting rubber strip 8 and the door panel, and extending the service life of the device. When the patient pulls down the pull rope 3, the elastic element 6 can buffer and limit the pulling force, protect the connection with the L-shaped mounting frame 5, and prevent the door panel from being damaged by sudden force.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
