Description

Technical Field

[0001] This application relates to the field of rehabilitation equipment technology, specifically a post-spinal surgery squatting rehabilitation assistive device. Background Technology

[0002] The spine, as a vital support structure of the human torso, plays a crucial role in protecting the spinal cord, maintaining body posture, and transmitting force between the upper and lower limbs. However, spinal diseases or injuries are quite common in clinical practice, such as herniated discs and spinal fractures. In severe cases, these conditions often require surgical treatment. After spinal surgery, the patient's rehabilitation process is of paramount importance. Squat training, as an effective exercise for strengthening lower limb muscles and enhancing body coordination and balance, is of great significance for the rehabilitation of patients after spinal surgery. Through proper squat training, patients can gradually restore lower limb function, improve their daily living self-care ability, and promote overall physical recovery.

[0003] However, in the early stages of spinal surgery rehabilitation, patients have weak lumbar strength and stability, and there are many risks in performing squat training on their own. On the one hand, patients have difficulty effectively controlling their lumbar movements during squats, which can easily lead to lumbar flexion. This can not only affect the rehabilitation effect, but may also cause secondary lumbar injury and aggravate the condition. On the other hand, without effective auxiliary support and traction, patients have poor limb stability when squatting, making it difficult to ensure the standard and proper form of the movements, thus affecting the quality and safety of rehabilitation training. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a post-spinal surgery squatting rehabilitation assistive device, which has advantages such as assisted traction and lumbar restraint, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a post-spinal surgery squatting rehabilitation assistive device, including a support frame, the support frame having a T-shaped structure, a T-shaped groove provided inside the support frame, a slider slidably connected inside the T-shaped groove, a lumbar support plate fixedly connected to the front of the slider, and elastic bands fixedly connected to both sides of the lumbar support plate. The slider has two armrest assemblies on its front side, which are arranged symmetrically and located on both sides of the lumbar support plate. The armrest assembly includes a shoulder width adjustment sleeve, which is fixedly connected to the front of the slider. An L-shaped block is slidably inserted into the inside of the shoulder width adjustment sleeve. A sliding limit sleeve is slidably inserted into the top of the L-shaped block. A forearm support plate is slidably connected to the top of the sliding limit sleeve. A lifting shaft is rotatably connected between the two inner sidewalls at the top of the T-shaped chute. The lifting shaft is parallel to the upper surface of the support frame. A winch is fixedly connected to the middle end of the lifting shaft. A rope is fixedly connected to the outer surface of the winch. The other end of the rope is fixedly connected to the slider.

[0006] Furthermore, the skin-contacting surface of the lumbar support plate is designed to be curved.

[0007] Through the above solution, the arc design can better fit the curve of the human waist, improve wearing comfort, and further enhance the support effect on the waist.

[0008] Furthermore, the top of each forearm support plate is made of silicone material, a limit ring is fixedly connected to the top of each forearm support plate, and a handle is fixedly connected to one end of each forearm support plate.

[0009] The above solutions prevent excessive pressure when the forearm is in direct contact with the forearm support, increasing comfort; the limiting ring prevents the forearm from slipping off the forearm support; and the handle makes it easy for the patient to grip, increasing stability and convenience.

[0010] Furthermore, a mounting plate is fixedly connected to the bottom of the support frame, and the mounting plate is connected to the external ground by bolts.

[0011] The above-mentioned method ensures that the support frame is securely installed on the ground and will not shake or shift due to patient movements during use, thus guaranteeing the safety of the entire device.

[0012] Furthermore, a worm gear is fixedly connected to one end of the lifting shaft, and a worm is rotatably connected to one side of the top of the support frame. The worm meshes with the worm gear, and one end of the worm is connected to an external power source.

[0013] The above scheme, through the worm gear transmission method, can achieve a large transmission ratio, enabling the power source to more precisely control the rotation of the lifting shaft, and thus precisely control the up and down movement of the waist support plate. At the same time, the worm gear transmission has self-locking properties, which can prevent the waist support plate from falling accidentally when needed, improving the reliability of the device.

[0014] Furthermore, the L-shaped block is fixedly connected to the shoulder width adjusting sleeve by bolts, and the L-shaped block is fixedly connected to the sliding limiting sleeve by bolts.

[0015] The above solution uses bolts for fixing, which allows for quick and stable fixation of the L-shaped block within the shoulder width adjustment sleeve and the sliding limit sleeve on the L-shaped block after adjustment. This ensures stable positioning after adjustment and allows the device to adapt to different patient body sizes.

[0016] Furthermore, the rope is a steel wire rope, which can withstand greater tensile force.

[0017] The above solution ensures that the traction lumbar support plate will not easily break during its up-and-down movement, thus ensuring the long-term stable operation of the device and guaranteeing patient safety.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects: This post-spinal surgery squatting rehabilitation aid device, through a lumbar support board and elastic band structure, achieves the purpose of effectively supporting and limiting the patient's lumbar region. The lumbar support board, together with the elastic bands on both sides and fixed with Velcro, can closely fit the patient's lumbar region, providing reliable support for the lumbar region during squatting, preventing lumbar bending, effectively reducing the stress on the lumbar region, and greatly reducing the risk of secondary lumbar injury. It provides strong protection for the patient's lumbar safety during the rehabilitation process. Through the combination structure of the shoulder width adjustment sleeve, L-shaped block, sliding limiting sleeve and forearm support board in the handrail assembly, it can adapt to different patient body sizes, improving the versatility and practicality of the device. By combining a lifting shaft, winch, rope, and worm gear transmission structure, the device achieves precise control over the up-and-down movement of the lumbar support plate. Controlling the forward and reverse rotation of the lifting shaft, through the winch and rope transmission, drives the lumbar support plate up and down. Furthermore, controlling the rotational speed of the lifting shaft allows for precise control of the lumbar support plate's movement speed, thus providing auxiliary traction during the patient's rehabilitation squats and ensuring limb stability. Simultaneously, the worm gear transmission allows for a large transmission ratio, enabling the power source to more precisely control the rotation of the lifting shaft. Moreover, the worm gear transmission has a self-locking feature, preventing the lumbar support plate from accidentally falling when needed, greatly improving the reliability and safety of the device. It provides the patient with stable and appropriate auxiliary traction, helping them gradually recover lower limb function. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a post-spinal surgery squatting rehabilitation aid includes a support frame 1, which has a T-shaped structure. The support frame 1 has a T-shaped groove 2 inside, and a slider 3 is slidably connected up and down inside the T-shaped groove 2. A lumbar support plate 4 is fixedly connected to the front of the slider 3, and elastic bands 5 are fixedly connected to both sides of the lumbar support plate 4. The two elastic bands 5 are fixed together by Velcro. The lumbar support plate 4 provides support and limits the patient's lower back, preventing bending of the lower back during squatting, reducing stress on the lower back, lowering the risk of secondary lower back injury, and ensuring the patient's safety during rehabilitation. The skin-contacting surface of the lumbar support plate 4 is arc-shaped, which better conforms to the curve of the human waist, improving wearing comfort and further enhancing the support effect on the lower back.

[0023] Please see Figure 1 , Figure 2 and Figure 5The slider 3 has two armrest assemblies 6 on its front side, arranged symmetrically on both sides of the lumbar support plate 4. Each armrest assembly 6 includes a shoulder width adjustment sleeve 601, which is fixedly connected to the front side of the slider 3. An L-shaped block 602 is horizontally slidably inserted into the inside of the shoulder width adjustment sleeve 601. The sliding arrangement of the L-shaped block 602 and the shoulder width adjustment sleeve 601 allows for use by patients with different shoulder widths. A sliding limiting sleeve 603 is vertically slidably inserted into the top of the L-shaped block 602. The sliding limiting sleeve 603 and the L-shaped block 602 allow for use by people of different heights. A forearm support plate 604 is vertically slidably connected to the top of the sliding limiting sleeve 603. The forearm support plate 604 and the sliding limiting sleeve 603 allow for use by people with different arm spans. Each forearm support plate 604 has a [missing information - likely a design element]. Made of silicone, each forearm support plate 604 has a limiting ring 10 fixedly connected to its top end, and a handle 11 fixedly connected to one end of each forearm support plate 604. The silicone material can prevent excessive pressure when the forearm is in direct contact with the forearm support plate 604, increasing the comfort of use. The limiting ring 10 can prevent the forearm from slipping off the forearm support plate 604, and the handle 11 is easy for the patient to grip, increasing the stability and convenience of use. The L-shaped block 602 is fixedly connected to the shoulder width adjustment sleeve 601 by bolts, and the L-shaped block 602 is fixedly connected to the sliding limiting sleeve 603 by bolts. The bolt connection makes it easy to quickly and firmly fix the L-shaped block 602 in the shoulder width adjustment sleeve 601 and the sliding limiting sleeve 603 on the L-shaped block 602 after adjusting the position of the L-shaped block 602 in the shoulder width adjustment sleeve 601 and the position of the sliding limiting sleeve 603 on the L-shaped block 602, ensuring the stability of the adjusted position and ensuring that the device can adapt to different patient body sizes.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The bottom of the support frame 1 is fixedly connected to the mounting plate 12, which is connected to the external ground by bolts. This fixing method ensures that the support frame 1 is stably installed on the ground and will not shake or shift due to the patient's movements during use, thus ensuring the safety of the entire device. The top of the T-shaped slide 2 is rotatably connected between the two inner side walls of the top. The lifting shaft 7 is parallel to the upper surface of the support frame 1. The middle end of the lifting shaft 7 is fixedly connected to the winch 8, and the outer surface of the winch 8 is fixedly connected to the rope 9. The other end of the rope 9 is fixedly connected to the slider. By controlling the forward and reverse rotation of the lifting shaft 7, the lumbar support plate 4 can be moved up and down. By controlling the rotation speed, the up and down movement speed of the lumbar support plate 4 can be controlled, providing auxiliary traction for the patient during rehabilitation squats, ensuring limb stability, and at the same time, the exercise intensity is low, making it suitable for patients to perform rehabilitation squat training.

[0025] Please see Figure 1 , Figure 2 and Figure 3Rope 9 is a steel wire rope, which can withstand a large amount of tension, ensuring that it will not easily break during the up-and-down movement of the lumbar support plate 4, thus ensuring the long-term stable operation of the device and the safety of patients. One end of the lifting shaft 7 is fixedly connected to a worm gear 13, and the top side of the support frame 1 is rotatably connected to a worm 14. The worm 14 is meshed with the worm gear 13, and one end of the worm 14 is connected to an external power source. Through the transmission method of the worm gear 13 and worm 14, a large transmission ratio can be achieved, allowing the power source to more accurately control the rotation of the lifting shaft 7, thereby accurately controlling the up-and-down movement of the lumbar support plate 4. At the same time, the transmission of the worm gear 13 and worm 14 has self-locking properties, which can prevent the lumbar support plate 4 from falling accidentally when needed, improving the reliability of the device.

[0026] It should be noted that the external power source can be selected according to actual needs, such as a motor, which provides power for the rotation of the worm gear 14, and then drives the lifting shaft 7 to rotate through the worm gear transmission mechanism, so as to realize the up and down movement of the lumbar support plate 4 to assist the patient in performing rehabilitation squat training.

[0027] The working principle of the above embodiment is as follows: First, the support frame 1 is securely connected to the external ground with bolts via the bottom mounting plate 12 to ensure that the support frame 1 will not shake or shift due to the patient's movements during use, providing a stable foundation for the entire rehabilitation training process. The patient stands in front of the support frame 1 and adjusts the device according to their own body size. The patient rests their lower back on the lumbar support plate 4. Since the skin-contact surface of the lumbar support plate 4 is arc-shaped, it can better conform to the curve of the human waist and improve the wearing comfort. The patient uses Velcro to fix the elastic bands 5 on both sides, so that the lumbar support plate 4 fits tightly against the waist and prevents the lower back from shaking during squatting. To reduce lumbar stress and the risk of secondary lumbar injury, the L-shaped block 602 is laterally slidable within the shoulder width adjustment sleeve 601 to accommodate the patient's shoulder width. Once adjusted, bolts are used to secure the L-shaped block 602 to the shoulder width adjustment sleeve 601, ensuring stability. The sliding limit sleeve 603 is then slid vertically onto the L-shaped block 602 to adjust to a suitable height. Bolts are then used to secure the L-shaped block 602 to the sliding limit sleeve 603 to meet the needs of patients of different heights. The forearm support plate 604 is longitudinally slidable at the top of the sliding limit sleeve 603. The forearm is positioned to accommodate the patient's arm span. After adjustment, the patient places their forearm on the forearm support plate 604. The silicone material at the top of the forearm support plate 604 prevents excessive pressure when the forearm is in direct contact with the plate, increasing comfort. Simultaneously, the limiting ring 10 prevents the forearm from slipping off the plate. The patient can also grip the handle 11, increasing stability and convenience. When the patient begins squat training, an external power source is activated, driving the worm gear 14 to rotate. Since the worm gear 14 is meshed with the worm wheel 13 at one end of the lifting shaft 7, a large transmission ratio can be achieved based on the transmission principle of the worm wheel 13 and worm gear 14. This allows the power source to more precisely control the rotation of the lifting shaft 7. When the lifting shaft 7 rotates, it drives the winch 8, which is fixedly connected at its middle, to rotate. The rope 9, which is fixedly connected to the outer surface of the winch 8, is a steel wire rope that can withstand a large amount of tension, ensuring that it will not easily break during the traction process. One end is fixedly connected to the slider 3. As the winch 8 rotates, the rope 9 will wind or release, thereby driving the slider 3 to slide up and down in the T-shaped groove 2 inside the support frame 1. Because the front of the slider 3 is fixedly connected to the waist support plate 4, the up and down sliding of the slider 3 will drive the waist support plate 4 to move up and down. By controlling the power source to drive the lifting shaft 7 to rotate in both directions, the up and down movement of the waist support plate 4 can be achieved.By controlling the rotational speed of the lifting shaft 7, the up-and-down movement speed of the lumbar support plate 4 can be precisely controlled, providing auxiliary traction for patients during rehabilitation squats, ensuring limb stability. The exercise intensity is low, making it suitable for patients to perform rehabilitation squat training. Furthermore, the worm gear 13 and worm 14 transmission have a self-locking mechanism, preventing the lumbar support plate 4 from accidentally falling if the patient pauses at a certain squatting position or if an unexpected situation occurs during training, thus improving the reliability of the device.
