Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training equipment, and in particular to a rehabilitation training device and method for patients with osteoporotic thoracolumbar fractures. Background Art

[0002] Osteoporotic thoracolumbar fractures are common injuries in elderly patients. Traditional rehabilitation training often relies on fixed braces or manual assistance, which has significant limitations. Fixed braces lack flexibility and are difficult to adapt to the individual patient's lumbar curve and fracture type, which can easily lead to excessive local pressure, causing pressure sores or aggravating pain. Manual-assisted training is limited by the operator's experience and cannot ensure the consistency of support stability and training intensity, increasing the risk of secondary injury. In addition, most existing devices do not have height adjustment functions, and patients need additional auxiliary equipment to change their body position, which makes training inefficient.

[0003] In the existing technology, some braces attempt to adopt a segmented adjustment structure, but the linkage mechanism is complex, the adjustment accuracy is insufficient, and there is a lack of real-time monitoring means, which cannot dynamically adapt to changes in the patient's body shape. In terms of support safety, traditional devices mostly rely on passive fixation and do not integrate active anti-derailment and inclination monitoring functions. During training, it is easy to slip or tilt due to unstable support. In response to the above problems, this technical solution proposes a rehabilitation training device, method and system for patients with osteoporotic thoracolumbar fractures.

[0023] The multi-stage linkage adjustment structure of the present invention drives the convex strips to be linked with the U-shaped seat through a micro-servo electric cylinder, so that the silicone support plate of the vertebral support component can accurately fit the patient's waist curve, and cooperate with the three-point support design to disperse the pressure, effectively relieve the local pain caused by fractures, and reduce the risk of secondary injury. The pelvic and sternal support components are linked by the H-shaped movable rod and the C-shaped frame to form an integrated support system, which synergistically stabilizes the thoracic and lumbar spine-pelvic region, avoids local compression caused by traditional fixation methods, and improves patient comfort. The lifting mechanism can adjust the height infinitely to assist patients in completing progressive training from lying to sitting position, accelerating the recovery process. The canvas belt and buckle design of the binding component facilitates quick adjustment of tightness to adapt to changes in body posture and reduce complications caused by over-tight or over-loose fixation.

[0033] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In order to more clearly explain and illustrate the technical solution and implementation of the present invention, preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

[0035] Example 1: The rehabilitation training device realizes the height adjustment function through the lifting mechanism 1. The base 11 of the lifting mechanism 1 is internally embedded with an electric motor 12, and its output shaft is connected to the screw rod 13 through a coupling. The top of the screw rod 13 is rotatably matched with the top plate 15 through a bearing. The back of the top plate 15 is fixed with a guide rail 14, and the front side of the bottom end of the guide rail 14 is connected to the rear side of the base 11. The rear end of the nut 16 is in rolling contact with the guide rail 14 through a roller, allowing the nut 16 to move stably along the axial direction of the screw rod 13. The lifting bars 17 are fixed on both sides of the nut 16, and the top of the lifting bar 17 is connected to the bottom of the cross block 31 of the vertebral support assembly 3. When the motor 12 is started, the screw rod 13 rotates to drive the nut 16 to rise and fall, driving the vertebral support assembly 3 to move synchronously, thereby realizing precise adjustment of the patient's position.

[0036] The vertebral support assembly 3 is composed of a cross block 31 and curved side strips 32 on the front and back sides to form the main frame. A silicone support plate 33 is fixed to the top of the end of the curved side strip 32, and the silicone support plate 33 contacts both sides of the patient's waist. The top of the cross block 31 is connected to the silicone strip 35 through a rubber bent rod 34, and the silicone strip 35 contacts the central area of the patient's waist to form a three-point support structure. The left side of the cross block 31 is hinged to a micro servo electric cylinder 39, and its telescopic axis is hinged to the bottom end of the left convex strip 37; the right convex strip 37 is hinged to the left end of the adjacent cross block 31 through a U-shaped seat 36 to achieve linked adjustment of the multi-section vertebral support assembly 3. The inclination sensor 38 monitors the horizontal inclination of the cross block 31 in real time to ensure support stability.

[0037] Embodiment 2: The pelvic support assembly 4 is connected to the left end of the vertebral support assembly 3. The top of its support block 41 is hinged to the arc-shaped support plate 44 through an axle pin. The arc-shaped support plate 44 is provided with a downwardly concave groove to support the patient's pelvis and upper buttocks. A U-shaped protrusion 42 is fixed to the bottom right side of the support block 41, and its right end is hinged to the bottom end of the micro-servo electric cylinder 39; an H-shaped movable rod 43 is fixed to the top right side, and its right end is hinged to the left end of the right cross block 31. By adjusting the angle of the H-shaped movable rod 43 through the telescopic micro-servo electric cylinder 39, the pitch angle of the arc-shaped support plate 44 can be changed synchronously to adapt to the pelvic shape of different patients. One end of the canvas belt 21 of the binding assembly 2 is fixed to the rear end of the arc-shaped support plate 44, and the other end is clamped to the front end face through the buckle 22 to achieve personalized fixation.

[0038] Example three: The sternum support assembly 5 is connected to the right end of the vertebral support assembly 3, and its C-shaped frame 51 can swing left and right along the central axis. The bottom is hinged with a sleeve 53, and the sleeve 53 can swing back and forth along the central axis. The left side of the bottom of the sleeve 53 is fixed with a raised end 54, which is hinged to the end of the left U-shaped seat 36; the right side is fixed with a fixing block 55, which is hinged to the end of the left convex strip 37. The back support plate 52 is hinged to the top of the C-shaped frame 51. By adjusting the swing angle of the C-shaped frame 51 and the sleeve 53, it can flexibly adapt to the undulating shape of the patient's chest. One end of the canvas belt 21 of the binding assembly 2 is fixed to the rear end of the back support plate 52, and the other end is connected to the front end through the buckle 22, so that the sternum is stably supported.

[0039] Example 4: In a comprehensive training scenario, after the lifting mechanism 1 adjusts the vertebral support assembly 3 to the appropriate height, the micro-servo cylinder 39 drives the left rib 37 to swing, driving the adjacent cross block 31 to work together, allowing the silicone support plate 33 to conform to the patient's lumbar curve. The angle of the curved support plate 44 of the pelvic support assembly 4 is simultaneously adjusted to ensure comfortable pelvic support. The angle of the C-shaped frame 51 and sleeve 53 of the sternum support assembly 5 is adjusted to ensure that the back support plate 52 conforms to the chest. After the canvas straps 21 of each lashing assembly 2 are secured with buckles 22, the inclination sensor 38 monitors the support assembly status in real time.

[0040] Based on the content of the preferred technical solution described above, the workflow of this technical solution is explained as follows: When the lifting mechanism 1 is started, the motor 12 drives the screw 13 to rotate through the coupling, and the nut 16 moves axially along the screw 13. The rear roller of the nut rolls in contact with the guide rail 14, and the lifting bar 17 rises and falls smoothly, thereby adjusting the height of the vertebral support assembly 3 to a comfortable position for the patient. The inclination sensor 38 at the bottom of the cross block 31 of the vertebral support assembly 3 monitors the horizontal state in real time. The left micro-servo electric cylinder 39 telescopes and drives the convex strip 37 to swing, and the adjacent cross blocks 31 are linked through the U-shaped seat 36, so that the silicone support plate 33 fits the curves on both sides of the patient's waist. At the same time, the silicone strip 35 at the top of the rubber curved rod 34 contacts the central area of the waist, forming a three-point support structure with the silicone support plate 33 to disperse the pressure on the waist.

[0041] The curved support plate 44 of the pelvic support assembly 4 is hinged to the right cross block 31 via an H-shaped movable rod 43. The U-shaped protrusion 42 at its bottom is linked to the micro-servo cylinder 39 to adjust the support plate's pitch angle to suit the patient's pelvic shape. One end of the canvas strap 21 is fixed to the rear end of the curved support plate 44, and the other end is connected to the front end face via a buckle 22 to achieve personalized fixation. The C-shaped frame 51 of the sternum support assembly 5 swings left and right along the central axis, and the sleeve 53 swings back and forth along the central axis. The linkage is achieved through the hinged connection between the raised end 54 and the U-shaped seat 36, and the fixed block 55 and the protrusion 37. The back support plate 52 conforms to the patient's chest curve, and its canvas strap 21 is fixed via a buckle 22, providing stable support for the sternum.

[0042] During training, if the support angle needs to be adjusted, the micro-servo electric cylinder 39 drives the left convex strip 37 to swing, driving the adjacent cross block 31 to work together, so that the silicone support plate 33 and silicone strip 35 of the vertebral support assembly 3 can fit the waist curve again; at the same time, the H-shaped movable rod 43 of the pelvic support assembly 4 moves with the right cross block 31 to adjust the angle of the arc support plate 44; the C-shaped frame 51 and sleeve 53 of the sternum support assembly 5 can swing adaptively according to the patient's chest pressure, or be manually fine-tuned to optimize the fit. After the coordinated adjustment of each component is completed, the device provides stable thoracolumbar support for the patient, assisting in completing rehabilitation training movements such as flexion, extension, and lateral bending. The support status is monitored in real time by the inclination sensor 38 throughout the entire process.

[0043] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention. Finally, it should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented.

A rehabilitation training method for patients with osteoporotic thoracolumbar fractures, characterized by: A rehabilitation training device for patients with osteoporotic thoracolumbar fractures according to any one of claims 1 to 9 specifically includes the following process: S1: The motor (12) drives the screw (13) to rotate through the coupling, and the nut (16) moves axially along the screw (13). The rear roller thereof rolls in contact with the guide rail (14), ensuring that the lifting bar (17) is lifted and lowered smoothly, thereby adjusting the height of the vertebral support assembly (3) to a comfortable position for the patient. The inclination sensor (38) at the bottom of the cross block (31) of the vertebral support assembly (3) monitors the horizontal state in real time. The left micro servo electric cylinder (39) telescopically drives the convex strip (37) to swing, and the adjacent cross blocks (31) are linked through the U-shaped seat (36), so that the silicone support plate (33) fits the curves on both sides of the patient's waist. At the same time, the silicone strip (35) at the top of the rubber curved rod (34) contacts the central area of the waist, forming a three-point support structure with the silicone support plate (33) to disperse the waist pressure. S2: The arc-shaped support plate (44) of the pelvic support assembly (4) is hinged to the right cross block (31) through an H-shaped movable rod (43), and the U-shaped protrusion (42) at its bottom is linked to the micro servo electric cylinder (39) to adjust the pitch angle of the support plate to adapt to the patient's pelvic shape; one end of the canvas belt (21) is fixed to the rear end of the arc-shaped support plate (44), and the other end is connected to the front end face through a buckle (22) to achieve personalized fixation, the C-shaped frame (51) of the sternum support assembly (5) swings left and right along the central axis, and the sleeve (53) swings back and forth along the central axis, and the linkage is achieved through the hinge connection between the raised end (54) and the U-shaped seat (36), the fixed block (55) and the protrusion (37); the back support plate (52) fits the patient's chest curve, and its canvas belt (21) is fixed through the buckle (22); S3: If the support angle needs to be adjusted, the micro servo electric cylinder (39) drives the left convex strip (37) to swing, driving the adjacent cross block (31) to move in conjunction, so that the silicone support plate (33) and the silicone strip (35) of the vertebral support component (3) are re-fitted to the waist curve; at the same time, the H-shaped movable rod (43) of the pelvic support component (4) moves with the right cross block (31) to adjust the angle of the arc support plate (44); the C-shaped frame (51) and the sleeve (53) of the sternum support component (5) swing adaptively according to the patient's chest pressure, or are manually fine-tuned to optimize the fit. After the coordinated adjustment of each component is completed, the device provides the patient with stable thoracolumbar support, assisting in completing rehabilitation training movements such as flexion, extension, and lateral bending. The support status is monitored in real time by the inclination sensor (38) throughout the entire process.
