Description

Technical Field

[0001] This invention relates to the field of thoracic vertebral repositioning technology, specifically a thoracic vertebral repositioning pad with a lateral force guiding structure. Background Technology

[0002] As the core segment of the spine, the thoracic spine connects to the cervical and lumbar spine and protects the thoracic organs. Dislocation of its facet joints can easily lead to symptoms such as back pain, chest tightness, and limb numbness. It can also affect the balance of spinal alignment, inducing a chain reaction of injuries. Precise repositioning can quickly correct vertebral misalignment, restore the normal physiological curvature and joint function of the thoracic spine, relieve pain and discomfort, improve local blood circulation, and prevent functional impairment caused by disease progression. It is crucial for maintaining spinal health and overall bodily stability.

[0003] In manual reduction of thoracic facet joint disorders, the traditional hand support method has significant limitations: the human hand is difficult to adapt to the different physiological curvatures of the thoracic spine in different patients, the stability of the support point is poor, the pressure distribution is uneven, and the width of the hand limits the precise targeted adjustment of a single target vertebra, which easily affects the reduction effect. As an alternative, the general towel roll can only provide a general support height, lacks a positioning design that matches the thoracic spine anatomy, has a fixed shape and no mechanical guidance function, and cannot achieve uniform pressure distribution, nor can it be used to directionally correct complex misalignments such as rotational and flexion-extension, resulting in insufficient reduction accuracy. Neither of these two solutions can meet the clinical need for efficient and accurate reduction. Therefore, we propose a thoracic spine reduction pad with a lateral force guidance structure. Summary of the Invention

[0004] The purpose of this invention is to provide a thoracic vertebral repositioning pad with a lateral force guiding structure to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions: A thoracic vertebral repositioning pad with a lateral force guiding structure includes a pad body and multiple snap-fit ​​plates. The pad body has a groove in the middle, and mounting plates are fixedly connected to the parallel side walls of the groove. The top surfaces of the two mounting plates are provided with snap-fit ​​grooves.

[0006] Each of the snap-fit ​​plates has a trapezoidal silicone block fixedly connected to its surface. The multiple trapezoidal silicone blocks have different specifications to meet the needs of different patients.

[0010] Preferably, the driving mechanism includes a lifting box slidably connected to the inner wall of a rectangular groove. The top surface of the lifting box has multiple square slots arranged in a linear array. Each square slot contains a square massage block slidably connected to it. The bottom surfaces of the multiple square massage blocks are fixedly connected to a lifting plate. The bottom surface of the lifting plate is fixedly connected to a semi-cylinder, and the bottom surface of the semi-cylinder is arc-shaped. A drive motor is fixedly installed on the bottom surface of the inner cavity of the connecting box. A reinforcing rod is fixedly connected to the output end of the drive motor. A synchronous wheel is fixedly sleeved on the circumferential surface of the reinforcing rod. A cam is fixedly connected to the end of the reinforcing rod away from the drive motor. The surface of the cam movably abuts against the surface of the semi-cylinder.

[0011] Preferably, reinforcing plates are fixedly connected to the four corners of the bottom surface of the lifting box, and limiting rods are fixedly connected to the four corners of the bottom surface of the lifting plate. The bottom ends of the four limiting rods are respectively in contact with the top surfaces of the four reinforcing plates. Springs are fixedly connected to the top surfaces of the four reinforcing plates, and the top ends of the four springs are respectively fixedly connected to the four corners of the bottom surface of the lifting plate. The limiting rods are located at the inner ring of the springs. Four electric push rods are also fixedly connected to the bottom surface of the inner cavity of the connecting box. The telescopic ends of the four electric push rods are respectively fixedly connected to the bottom surfaces of the four reinforcing plates.

[0012] Preferably, the transmission mechanism includes two piston cylinders, which are respectively fixedly connected to the inner walls of the two sides of the connecting box and are arranged symmetrically. The inner cavities of the two piston cylinders are slidably connected to piston plates, and the surfaces of the two piston plates are fixedly connected to pull rods. The ends of the two pull rods that are close to each other are rotatably connected to connecting rods two, and the ends of the two connecting rods that are close to each other are rotatably connected to connecting rods one. The rotation of connecting rods one is used to drive the corresponding pull rods to slide back and forth inside the piston cylinders.

[0013] Preferably, the transmission mechanism further includes two support frames, the bottom of which is fixedly connected to the bottom surface of the inner cavity of the connecting box, the top of which is rotatably sleeved with a second synchronous wheel, and the two second synchronous wheels and the first synchronous wheel are together sleeved with a synchronous belt, the ends of the two first connecting rods that are close to each other are respectively fixedly connected to the ends of the two second synchronous wheels, and the ends of the two first connecting rods that are close to each other are respectively rotatably sleeved on the two support frames.

[0014] Preferably, the ends of the two piston cylinders that are far apart from each other are fixedly closed. Each end of the two piston cylinders that is far apart from each other is provided with an air inlet and an air outlet. One-way valve 1 is fixedly connected to each of the two air inlets. Air inlet pipe 2 is fixedly connected to each of the two air inlet pipes 2. Two air supply hoses are fixedly connected to each of the two air supply hoses. The air inlet ends of the four air supply hoses are respectively fixedly connected to the exhaust ends of the four connecting pipes. One-way valve 2 is fixedly connected to each of the two exhaust ports. Exhaust pipe is fixedly connected to the exhaust ends of the two one-way valves 2.

[0015] The beneficial effects of this invention are: 1. This invention utilizes grooves, trapezoidal silicone blocks, and snap-fit ​​plates. The groove in the center of the pad allows for precise positioning of the thoracic spinous processes. With trapezoidal silicone blocks of varying sizes, the snap-fit ​​plate and mounting plate can be quickly assembled to fit the patient's thoracic spine morphology and misalignment type. The lateral force guiding structure formed by the trapezoidal silicone blocks decomposes the surgeon's vertical pressure into directional lateral corrective force, providing precise guidance for complex misalignments such as rotational and pitching types. This significantly improves the accuracy of repositioning, allowing different patients to achieve personalized and targeted corrective effects, effectively restoring the normal physiological curvature of the thoracic spine and joint function. Furthermore, the detachable design of the snap-fit ​​plate and mounting plate facilitates cleaning and disinfection of the trapezoidal silicone blocks.

[0016] 2. This invention utilizes a drive motor, cam, and springs. The drive motor rotates the cam, which, in conjunction with the spring and limit rod, drives the square massage block to repeatedly move in and out of the square slot of the lifting box. This transmits cyclical massage force to the pad, pre-relaxing the muscles around the thoracic spine to reduce repositioning resistance. When it is necessary to reduce the pressure on the surgeon's hands, after the square massage block is fully inserted into the square slot, four electric push rods push the lifting box upwards, applying a stable compressive force to the thoracic spine through force transmission. This synergizes with the surgeon's pressure, significantly reducing the strain on the surgeon's hands. It also avoids the problem of the surgeon's finger and wrist joints being compressed by the patient's weight in traditional hand support methods, improving occupational safety and operational smoothness, and increasing treatment efficiency.

[0017] 3. This invention, through the arrangement of piston cylinder, piston plate, and suction cup, etc., after the drive motor is started, synchronous wheel one drives synchronous wheel two to rotate via synchronous belt. Through connecting rod one and connecting rod two, the piston plate slides back and forth in the piston cylinder, continuously drawing gas from the suction cup and expelling it through the exhaust pipe, forming a negative pressure adsorption onto the treatment bed, effectively preventing the pad from shifting during repositioning. When disassembling and moving the overall structure, the air pressure can be balanced and the fixation released by unscrewing the sealing cap of air inlet pipe one, which is beneficial to improving the safety and convenience of the overall structure.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-8 As shown, the thoracic spine reduction pad with lateral force guidance structure includes a pad body 1 and multiple snap-fit ​​plates 5. A groove 2 is provided in the middle of the pad body 1. Mounting plates 3 are fixedly connected to the parallel side walls of the groove 2. The top surfaces of the two mounting plates 3 are provided with snap-fit ​​grooves 4. A trapezoidal silicone block 6 is fixedly connected to the surface of each snap-fit ​​plate 5. The multiple trapezoidal silicone blocks 6 have different specifications to meet the needs of different patients. Each snap-fit ​​plate 5 is movably inserted into the snap-fit ​​groove 4.

[0022] In practice, based on the differences in the morphology of the patient's thoracic spine and the type of misalignment, a trapezoidal silicone block 6 with appropriate specifications is selected. The block is then connected to the mounting plate 3 with the top slot 4 of the mounting plate 3, which is fixed to the two side walls of the groove 2 of the pad 1, through the snap-fit ​​plate 5 fixed on its surface, so as to complete the precise assembly of the trapezoidal silicone block 6. When the patient lies supine, the spinous processes of the thoracic vertebrae are embedded in the grooves 2 in the middle of the pad 1. The trapezoidal silicone blocks 6 assembled on both sides fit against the sides of the thoracic vertebrae. When the surgeon applies the pressure technique, the trapezoidal silicone blocks 6, with their specific shape, form a lateral force guiding structure, decomposing the vertical pressure into a directional lateral corrective force, accurately guiding the misaligned thoracic vertebrae back to their normal position, and achieving targeted reduction and correction under different conditions.

[0023] As a technical optimization of the present invention, the bottom surface of the pad 1 is provided with a connecting mechanism 7. The surface of the connecting mechanism 7 is respectively provided with a driving mechanism 8 for enhancing the effect of thoracic spine orthopedics and a transmission mechanism 9 for enhancing the overall stability of use. The connecting mechanism 7 includes a connecting cover plate 71 detachably connected to the bottom surface of the pad 1, and the top surface of the connecting cover plate 71 is in contact with the bottom surface of the pad 1. The bottom surface of the connecting cover plate 71 is detachably connected to a connecting box 72. A rectangular groove 74 is opened in the middle of the top surface of the connecting cover plate 71. A connecting pipe 73 is fixedly sleeved at each of the four corners of the bottom surface of the connecting box 72. The air inlet end of each of the four connecting pipes 73 is fixedly connected to a suction cup 75. The surface of each of the four suction cups 75 is fixedly connected to an air inlet pipe 76. The top end of each of the four air inlet pipes 76 is threadedly connected to a sealing cap 77.

[0024] In practice, the connecting mechanism 7 is first attached to the bottom surface of the pad 1 via the connecting cover plate 71 and detachably connected. Then, the connecting box 72 is assembled onto the bottom surface of the connecting cover plate 71. The gas in the four suction cups 75 can be discharged through the four connecting pipes 73. The gas is discharged through the connecting pipes 73, so that the suction cups 75 are tightly adsorbed onto the surface of the treatment bed. The atmospheric pressure is used to firmly fix the whole device, which significantly enhances the stability of use during the repositioning operation and avoids the pad 1 from shifting and affecting the repositioning effect. When it is necessary to move or disassemble the device, the sealing cap 77 at the top of the air inlet pipe 76 is unscrewed. The outside gas enters the suction cup 75 through the air inlet pipe 76, balances the air pressure inside and outside the suction cup 75, and releases the fixed state of the suction cup 75, so as to realize the flexible movement of the whole structure.

[0025] As a technical optimization of the present invention, the driving mechanism 8 includes a lifting box 81 slidably connected to the inner wall of the rectangular groove 74. Multiple square grooves 82 are linearly arrayed through the top surface of the lifting box 81. A square massage block 84 is slidably connected in each square groove 82. A lifting plate 83 is fixedly connected to the bottom surface of the multiple square massage blocks 84. A semi-cylinder 89 is fixedly connected to the bottom surface of the lifting plate 83, and the bottom surface of the semi-cylinder 89 is arc-shaped. A drive motor 85 is fixedly installed on the bottom surface of the inner cavity of the connecting box 72. A reinforcing rod 86 is fixedly connected to the output end of the drive motor 85. A synchronous wheel 87 is fixedly sleeved on the circumferential surface of the reinforcing rod 86. A protrusion is fixedly connected to the end of the reinforcing rod 86 away from the drive motor 85. The surfaces of wheel 88 and cam 88 are in movable contact with the surface of semi-cylinder 89. Reinforcing plates 802 are fixedly connected to the four corners of the bottom surface of lifting box 81. Limiting rods 801 are fixedly connected to the four corners of the bottom surface of lifting plate 83. The bottom ends of the four limiting rods 801 are in movable contact with the top surfaces of the four reinforcing plates 802. Springs 803 are fixedly connected to the top surfaces of the four reinforcing plates 802. The top ends of the four springs 803 are fixedly connected to the four corners of the bottom surface of lifting plate 83. The limiting rods 801 are located in the inner ring of the springs 803. Four electric push rods 804 are also fixedly connected to the bottom surface of the inner cavity of connecting box 72. The telescopic ends of the four electric push rods 804 are fixedly connected to the bottom surfaces of the four reinforcing plates 802.

[0026] In practice, when the patient's thoracic spine needs to be massaged, the output end of the push rod drive motor 85 drives the reinforcing rod 86 to rotate. The reinforcing rod 86 synchronously drives the cam 88 to rotate. The cam 88 rotates and continuously contacts and separates from the semi-cylinder 89. The lifting plate 83 forms a movable limit with the reinforcing plate 802 through the limiting rod 801. At the same time, the four springs 803 provide elastic reset. The rotation of the cam 88 will alternately push the lifting plate 83 to move up and down along the limiting rod 801, thereby driving multiple square massage blocks 84 to move up and down synchronously. This causes the multiple square massage blocks 84 to repeatedly enter and exit the square groove 82 on the top surface of the lifting box 81, transmitting cyclic massage force to the pad 1 and helping to loosen the muscles around the thoracic spine to reduce reset resistance. When it is necessary to reduce the pressure on the surgeon's hands, the output end of the drive motor 85 drives the cam 88 to move away from the semi-cylinder 89. At this time, the contraction force of the spring 803 drives multiple square massage blocks 84 to fully enter the square groove 82 (the bottom end of the limit rod 801 abuts against the top surface of the reinforcing plate 802, and the top surface of the square massage blocks 84 is on the same horizontal plane as the top surface of the lifting box 81). Then, the extension and retraction ends of the four electric push rods 804 push the reinforcing plate 802 and the lifting box 81 to rise as a whole. Through the force transmission between the square massage blocks 84 and the pad 1, a stable squeezing force is applied to the thoracic spine, which works in synergy with the surgeon's pressure to effectively reduce the burden on the surgeon's hands and improve the labor-saving and accuracy of the repositioning operation.

[0027] As a technical optimization of the present invention, the transmission mechanism 9 includes two piston cylinders 91, which are respectively fixedly connected to the inner walls of the two sides of the connecting box 72, and are arranged symmetrically. A piston plate is slidably connected to the inner cavity of each piston cylinder 91, and a pull rod 92 is fixedly connected to the surface of each piston plate. A connecting rod 93 is rotatably connected to the adjacent ends of the two pull rods 92, and a connecting rod 94 is rotatably connected to the adjacent ends of the two connecting rods 93. The connecting rod 94 rotates to drive the corresponding pull rod 92 to slide back and forth within the piston cylinder 91. The transmission mechanism 9 also includes two support frames 95, the bottoms of which are fixedly connected to the bottom surface of the inner cavity of the connecting box 72, and the tops of which are rotatably fitted with synchronous pulleys 96. The synchronous pulleys 96 and synchronous pulleys 96 are connected to the inner cavity of the connecting box 72. The first wheel 87 is connected to the synchronous belt 97. The ends of the two connecting rods 94 that are close to each other are fixedly connected to the ends of the two synchronous pulleys 96. The ends of the two connecting rods 94 that are close to each other are rotatably connected to the two support frames 95. The ends of the two piston cylinders 91 that are far apart from each other are fixedly closed. The ends of the two piston cylinders 91 that are far apart from each other are provided with air inlets and exhaust ports. The two air inlets are fixedly connected to the one-way valves 98. The air inlets of the two one-way valves 98 are fixedly connected to the air inlet pipes 99. The two air inlet pipes 99 are fixedly connected to the two air supply hoses 901. The air inlets of the four air supply hoses 901 are fixedly connected to the exhaust ports of the four connecting pipes 73. The two exhaust ports are fixedly connected to the one-way valves 902. The exhaust ports of the two one-way valves 902 are fixedly connected to the exhaust ports of the two one-way valves 903.

[0028] In specific implementation, after the drive motor 85 starts, the output end of the drive motor 85 drives the reinforcing rod 86 and the synchronous wheel 87 on the surface to rotate synchronously. The synchronous wheel 87 drives the synchronous wheel 96 on the top of the two support frames 95 to rotate synchronously through the synchronous belt 97. When the synchronous wheel 96 rotates, it drives the connecting rod 94 to rotate, which in turn drives the connecting rod 93 to pull the corresponding pull rod 92, so that the pull rod 92 drives the piston plate to slide back and forth in the piston cylinder 91. When the piston plate continuously approaches and slides towards the synchronous wheel 96, the piston cylinder 91 forms an airflow channel with the connecting pipe 73 through the one-way valve 98 at the air inlet, the air inlet pipe 99, and the air delivery hose 901, continuously drawing gas from the suction cup 75. As the piston plate slides away from the synchronous wheel 96, the gas is discharged through the one-way valve 902 and exhaust pipe 903 at the exhaust port, creating a negative pressure inside the suction cup 75, which firmly adheres to the surface of the treatment bed, thus achieving stable fixation of the entire device. During the entire process of massaging the patient by rotating the drive motor 85, the gas inside the suction cup 75 is automatically discharged without additional manual operation, significantly improving the convenience and stability of the overall structure fixation.

[0029] In use, the connecting mechanism 7 is first attached to the bottom surface of the pad 1 via the connecting cover plate 71 and detachably connected. Then, the connecting box 72 is assembled. According to the patient's thoracic vertebral morphology and misalignment type, a suitable trapezoidal silicone block 6 is selected and movably inserted into the snap-fit ​​groove 4 on the top surface of the mounting plate 3 via the snap-fit ​​plate 5 to complete the precise assembly. After the patient lies supine, the spinous process of the thoracic vertebra is embedded in the groove 2 in the middle of the pad 1, and the trapezoidal silicone blocks 6 on both sides fit against the two sides of the thoracic vertebra, providing a basis for directional reduction. After the drive motor 85 is started, on the one hand, the output end of the drive motor 85 drives the reinforcing rod 86 and the cam 88 to rotate. The cam 88 and the semi-cylinder 89 alternately abut and separate. Under the limiting action of the limiting rod 801 and the elastic reset action of the spring 803, the lifting plate 83 drives the square massage block 84 to repeatedly enter and exit the square groove 82 of the lifting box 81, transmitting cyclic massage force to the pad body 1 to relax the muscles around the thoracic spine. If it is necessary to reduce the pressure of the surgeon, the drive motor 85 drives the cam 88 to disengage from the semi-cylinder 89, the spring 803 contracts so that the square massage block 84 is fully inserted into the square groove 82, and then the four electric push rods 804 extend, pushing the reinforcing plate 802 and the lifting box 81 to rise. Through the square massage block 84 and the pad 1, a stable squeezing force is applied to the thoracic spine, which works in conjunction with the pressure of the surgeon. On the other hand, the drive motor 85 drives the synchronous pulley 87 on the reinforcing rod 86 to rotate, and drives the two synchronous pulleys 96 to rotate through the synchronous belt 97. This, in turn, drives the connecting rod 94 and the connecting rod 93 to pull the pull rod 92, causing the piston plate to slide back and forth in the piston cylinder 91. When the piston plate is close to the synchronous pulley 96, the gas in the suction cup 75 is drawn out through the one-way valve 98, the air inlet pipe 99, the air delivery hose 901 and the connecting pipe 73. When the piston plate is away from the synchronous pulley 96, the gas is discharged through the one-way valve 902 and the exhaust pipe 903, so that the suction cup 75 forms a negative pressure and adheres to the treatment bed, enhancing the stability of the device. When the operator applies the pressure technique, the trapezoidal silicone block 6 decomposes the vertical pressure into a directional lateral corrective force, guiding the misaligned thoracic vertebrae to reposition, thus completing a personalized and precise thoracic vertebral correction operation. When it is necessary to disassemble and move the whole unit, unscrew the sealing cap 77 of the air inlet pipe 76, and the gas enters the suction cup 75 to balance the air pressure, thereby releasing the fixation of the whole unit.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
