Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a spinal correction and recovery device. Background Technology

[0002] The development of spinal orthopedic devices stems from the clinical need for intervention in spinal deformities and functional impairments. Early devices were mainly rigid braces, which limited the development of deformities through static fixation, but these had problems such as muscle disuse atrophy, skin pressure injury, and inability to adapt to dynamic activities. While subsequent 3D-printed personalized braces improved fit, they still did not overcome the limitations of passive fixation. Moreover, traditional orthopedic devices are mostly structurally fixed designs, which are difficult to adapt to different patients' spinal tilt states and daily changes in body posture, resulting in insufficient flexibility. At the same time, existing orthopedic solutions often rely on a single shoulder or lumbar region to provide horizontal corrective force, leading to uneven force distribution on the patient's body and increasing the risk of spinal pressure injury. Summary of the Invention

[0010] As a further aspect of the present invention: a plurality of corrective push rods are provided between the two transverse adjustment frames, the output end of the corrective push rods is rotatably connected to a docking seat, a corrective support plate is fixedly connected to one side of the docking seat, a corrective air cushion is fixedly connected to one side of both the limiting support plate and the corrective support plate, an air guide pipe is fixedly connected to one side of the corrective air cushion, an air pump is fixedly connected to one end of the air guide pipe, and an exhaust valve is fixedly installed in the middle of the air guide pipe.

[0011] As a further aspect of the present invention: heating wires are embedded inside the interior of several of the limiting plates, and a vibrator is fixedly installed on the side of the several limiting plates away from the air cushion.

[0012] As a further aspect of the present invention: edge positioning components are fixedly connected to the inner sidewall edges of both of the supporting protective plates. The edge positioning components include closed positioning frames, and a closed air cushion is fixedly installed on the inner wall of the closed positioning frames.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention achieves the installation and fixation of the patient's waist and shoulders by separately setting the lumbar fixation component and the shoulder fixation component, respectively. At the same time, the connection between the lumbar fixation component and the shoulder fixation component is achieved by setting a rotatable central fixation frame. The tilting and rotation of the central fixation frame can adapt to the different tilting states of the spine of different patients. Compared with the traditional structural fixed correction device, the correction device of this application adopts a rotatable central fixation frame, which can be used to correct the body posture of patients with different body postures and requires more flexibility. At the same time, the present application achieves the displacement control of the shoulder fixation frame through the cooperation of linear motor and adjusting motor, and its correction force is more uniform and controllable, with less pressure damage to the patient's spine. The positioning adjustment component of the present invention is driven by linear motors on both sides to move the movable seat, which is then clamped and pressed against by both sides of the central fixed frame. By changing the pushing stroke of the linear motors, the adjustment gear and the tooth groove can be stably engaged in different tilt states of the central fixed frame. The engagement of the adjustment gear and the tooth groove makes the sliding displacement of the positioning adjustment component and the central fixed plate stable and controllable. This invention utilizes multiple dispersed support components installed in the center of the central fixing frame to support the patient's waist and back, providing sufficient corrective pressure in the horizontal direction. This avoids uneven force distribution on the patient's body, which could lead to injury, and also improves installation stability. By adjusting the posture of different support plates and the inflation volume of the air cushion behind the support plates, targeted force correction can be applied to the patient's spine. Heating the limiting support plate with an electric heater provides heat therapy to the patient's body, and combined with the activation of the vibrator, it provides a vibratory massage, effectively relieving muscle stiffness and reducing discomfort from long-term use of the device.

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figure 1 and Figure 2As shown in the embodiment of the present invention, a spinal correction and recovery device is provided, including a lumbar fixation frame 1 and a shoulder fixation frame 2, which are used to install and fix the patient's lumbar and shoulder respectively. Specifically, the installation and fixation are as follows: a lumbar fixation strap 102 is fixedly connected to both ends of the lumbar fixation frame 1, and a shoulder fixation plate 202 is fixedly connected to both ends of the shoulder fixation frame 2. A contoured groove is provided on one side of the shoulder fixation plate 202 to stably fit the patient's shoulder and improve the comfort of use. A shoulder fixation strap 203 is fixedly connected to the edge of the shoulder fixation plate 202. The lumbar fixation strap 102 and the shoulder fixation strap 203 are adjustable straps used to install and fix the lumbar fixation frame 1 and the shoulder fixation frame 2 to the patient's lumbar and shoulder. Alternatively, other device structures in the prior art that can achieve this function can be used instead.

[0021] A middle fixation frame 3 is provided between the lumbar fixation frame 1 and the shoulder fixation frame 2. The bottom of the middle fixation frame 3 is rotatably installed with the lumbar fixation frame 1, and the top of the middle fixation frame 3 is slidably connected with the shoulder fixation frame 2, so that the middle fixation frame 3 can tilt and rotate to adapt to the patient's tilted spine. This avoids the problem of excessive pressure on the patient's spine and injury caused by directly using a vertically fixed support frame for correction, and the difficulty in adapting and stabilizing the installation. The middle of the shoulder fixation frame 2 has a movable groove 201, and the top of the middle fixation frame 3 is slidably disposed in the movable groove 201. In one embodiment, see Figure 3The inner walls of the movable groove 201 are provided with positioning adjustment components on both sides for adjusting and limiting the posture of the central fixed frame 3. The positioning adjustment components include a linear motor 501, the output end of which is rotatably connected to a movable seat 502. The edge of the movable seat 502 is slidably connected to the inner cavity of the shoulder fixed frame 2. An adjustment motor is fixedly installed on one side of the movable seat 502, and an adjustment gear 503 is fixedly connected to the output end of the adjustment motor. The central fixed frame 3 has toothed grooves 504 on both sides. The two adjustment gears 503 are respectively meshed with the toothed grooves 504 on both sides. The movable seat 502 is moved by the linear motors 501 on both sides, and is clamped and held by the two sides of the central fixed frame 3. By changing the pushing stroke of the linear motor 501, the adjustment gears 503 and the toothed grooves 504 can be stably meshed in different tilt states of the central fixed frame 3. By using the meshing of the adjustment gears 503 and the toothed grooves 504, the sliding displacement of the positioning adjustment component and the central fixed plate is stable and controllable. That is, when the shoulder fixation frame 2 is fixed to the patient's shoulder by the shoulder fixation strap 203, the rotation of the adjusting gear 503 will drive the shoulder fixation frame 2 to move up and down along the middle fixation frame 3. Since the middle fixation frame 3 is tilted, the shoulder fixation frame 2 will apply a part of the horizontal force during the tilting and lifting movement, thereby realizing the horizontal correction force on the patient's spine. Compared with the traditional structural fixed correction device, the correction device of this application adopts a rotatable middle fixation frame 3, which can be used to correct the body posture of patients with different body postures. It is more flexible to use. At the same time, this application realizes the displacement control of the shoulder fixation frame 2 through the cooperation of the linear motor 501 and the adjusting motor. Its correction force is more uniform and controllable, and the pressure damage to the patient's spine is small.

[0022] In one embodiment, the central support frame 3 is provided with a central support mechanism 4 for supporting the patient's lumbar region. The central support mechanism 4 includes two symmetrically arranged support components. In this embodiment, the two support components support the patient's lumbar region from both sides of the waist. Please refer to [link to relevant documentation]. Figure 4 and Figure 7 The support component includes a connecting block 401, a rotating seat 410 rotatably connected to the top of the connecting block 401, a rotating rod 402 fixedly connected to the top of the rotating seat 410, and a support guard plate 403 fixedly connected to one side of the rotating rod 402. By improving the setting of the rotating seat 410 and the rotating rod 402, the support guard plate 403 can be rotated and adjusted to provide stable support and protection for the waist of patients with different waist sizes. In one embodiment, to further provide a greater adjustment range, extension blocks 409 are fixedly connected to the side of each of the two connecting blocks 401 near the mounting block 302. Positioning bolts 412 are threadedly connected to the middle of each of the two extension blocks 409. Through the docking installation between the positioning bolts 412 and the waist fixing bracket 1, the connecting blocks 401 are adjusted and limited, thereby expanding the movement range of the support component.

[0023] In one embodiment, to ensure controllable rotation angles of the two support components and avoid excessive differences in rotation tilt angles between the two support components, which could lead to excessive force differences on both sides of the patient's waist and affect the patient's normal physical recovery, this application includes a locking bolt 413 threadedly connected to the middle of the connecting block 401. One end of the locking bolt 413 is fixedly connected to a friction pad, one side of which is in close contact with the edge of the rotating seat 410. A scale line 411 is provided on the top of the connecting block 401 along the edge of the rotating seat 410. A section of the rotating seat 410 near the scale line 411... An indicator line is provided on the side center. By comparing the indicator line with the scale line 411, the rotation range of the support plate 403 can be easily and intuitively understood. In conjunction with the rotation of the locking bolt 413, the friction pad is pushed out, so that the friction pad is in tight contact with the edge of the rotating seat 410, thereby fixing the posture of the rotating seat 410. In order to improve the installation stability between the two support plates 403 and the entire device and the patient's body, several connecting straps 408 are fixedly connected between the edges of the two support plates 403. Each of the connecting straps 408 has a connecting buckle fixedly installed in the middle.

[0024] In one embodiment, see Figure 4 and Figure 5 The inner wall of the support plate 403 is provided with a correction component, which includes two parallel transverse adjustment frames 404. The inner walls of the two transverse adjustment frames 404 are slidably connected with sliding plates. One side of the sliding plate is rotatably connected to a limiting plate 405. One side edge of the limiting plate 405 protrudes outward and is inclined. By setting the transverse adjustment frames 404 and the sliding plates, the limiting plate 405 itself can be moved and adjusted, thereby limiting and supporting the patient's waist on both sides, improving the fit between the support component and the patient's body. The limiting plate 405 itself can rotate, so it can contact the patient's body in different postures to provide corresponding adaptation and support.

[0025] In one embodiment, see Figure 5 and Figure 6To provide sufficient corrective pressure in the horizontal direction and avoid uneven force on the patient's body caused by the shoulder alone providing horizontal corrective force, this application provides several corrective push rods 406 between two transverse adjustment frames 404. The output end of the corrective push rod 406 is rotatably connected to a docking seat, and a corrective support plate 407 is fixedly connected to one side of the docking seat. In one embodiment, an orthopedic air cushion 414 is fixedly connected to one side of both the limiting support plate 405 and the orthopedic support plate 407. An air duct 416 is fixedly connected to one side of the orthopedic air cushion 414. An air pump is fixedly connected to one end of the air duct 416, and an exhaust valve 417 is fixedly installed in the middle of the air duct 416. The air pump is activated to inflate the orthopedic air cushion 414 through the air duct 416, thereby changing the shape of the orthopedic air cushion 414 to improve the fit between the orthopedic support plate 407 and the limiting support plate 405 and the patient's body, and at the same time improve the patient's comfort.

[0026] Furthermore, in one embodiment, heating wires 415 are embedded inside several limiting plates 405, and vibrators 418 are fixedly installed on the side of several limiting plates 405 away from the air cushion. The limiting plates 405 are heated by the heating wires to achieve heat therapy on the patient's body. When the vibrators 418 are activated, they provide vibration massage to the patient's body, effectively relieving muscle stiffness and reducing discomfort from long-term use of the device.

[0027] In one embodiment, see Figure 4 and Figure 8 To improve the posture stability of the support plate 403 and prevent it from being pulled by the connecting strap 408 and undergoing excessive deformation and bending, this application has edge positioning members 6 fixedly connected to the inner sidewall edges of both support plates 403. Please refer to [link to relevant documentation]. Figure 9 The edge positioning component 6 includes a closed positioning frame 601, a closed air cushion 603 is fixedly installed on the inner wall of the closed positioning frame 601, and a closed contact plate 602 is fixedly connected to one side of the closed air cushion 603.

[0028] In one embodiment, a ventilation pipe 604 is provided on one side of the sealed air cushion 603. A ventilation control valve is fixedly installed in the middle of the ventilation pipe 604. A ventilation frame is fixedly connected to one side of the ventilation pipe 604. A ventilation groove 605 is provided on the edge of the ventilation frame near the supporting plate 403. By setting the ventilation pipe 604 and the ventilation groove 605, this application realizes the ventilation and cooling operation of the gap between the inside of the supporting plate 403 and the patient's body, and assists the patient in sweating and heat dissipation.

[0029] In one embodiment, see Figure 4 and Figure 7To allow for adjustment of the position of the central fixing frame when needed for better usability, the top of the waist fixing frame 1 is provided with a mounting groove 101. A central seat is slidably connected to the middle of the inner wall of the mounting groove 101. Two connecting blocks 401 and an extension block 409 are slidably installed inside the mounting groove 101. A rotating bracket 301 is fixedly connected to the top of the central seat. The bottom of the central fixing frame 3 is rotatably connected to the rotating bracket 301. Mounting blocks 302 are fixedly connected to both ends of the central fixing frame 3. Mounting bolts 303 are rotatably connected to the middle of the two mounting blocks 302. Several mounting screw holes are provided on the inner wall of the movable groove 201. The bottom of the mounting bolts 303 is threadedly connected to the mounting screw holes.

[0030] When using this invention, the device is first installed. The specific operation is as follows: First, the two ends of the shoulder fixation frame 2 are fixed to the patient's shoulders using the shoulder fixation strap 203. Then, the waist fixation frame 1 is bound to the patient's waist using the waist fixation strap 102. Then, the two support plates 403 are rotated to surround and protect the patient's waist. When rotating the support plates 403, pay attention to the position of the indicator line and scale line 411 to ensure that the rotation amplitude of the two support plates 403 is relatively consistent. At the same time, adjust the position of the sliding plate and rotate the adjustment limit plate 405 according to the patient's body shape. Meanwhile, the correction push rods 406 on both sides drive the correction plate 407 to move, so that the correction air cushion 414 is in close contact with the patient's body. Then, the rotating seat 410 is fixed by rotating the locking bolt 413, thereby limiting the support plates 403. Finally, the two support plates 403 are connected and positioned by the connecting strap 408 to complete the installation of the device. In use, the linear motors 501 on both sides drive the movable seat 502 to move, which in turn drives the two adjusting gears 503 to move. The adjusting gears 503 contact with the two sides of the central fixing frame 3 to tighten and limit it. At the same time, the adjusting motor drives the adjusting gears 503 to grab and drive the shoulder fixing frame 2 to move up and down along the central fixing frame 3. The horizontal force applied during the up and down movement is used to achieve horizontal correction force on the patient's spine. At the same time, the air pump inflates the correction air pad 414 through the air tube, and the exhaust valve 417 and exhaust pipe are used to adjust the inflation degree of the correction air pad 414 at different positions, changing its push-out distance and push-out force, thereby changing the direction of the correction force on the patient's body and assisting in the correction operation of the patient's spine.

[0031] The above-disclosed embodiments are merely a few specific examples of the present invention.
