Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an upright scoliosis correction and fixation device. Background Technology

[0002] Scoliosis is a spinal deformity associated with factors such as incorrect posture or poor habits. It commonly occurs during adolescence and is characterized by one or more segments of the spine curving laterally in the coronal plane, deviating from the midline. It is often accompanied by changes in the sagittal plane's physiological curvature and vertebral rotation in the horizontal plane. Without timely intervention, the deformity will gradually worsen, affecting the patient's posture, cardiopulmonary function, and potentially leading to chronic pain and significantly reducing quality of life. Currently, for moderate scoliosis (Cobb angle typically between 20° and 40°), non-surgical treatment primarily involves external orthotic braces, such as the Boston brace and the Senu brace. These traditional braces consist of a rigid plastic shell that encloses the trunk, correcting the curvature by applying pressure at specific points.

[0003] Existing braces are often static and passive correction methods, which cannot be dynamically adjusted according to changes in the patient's posture. Furthermore, the corrective force is constant and cannot provide precise fine-tuning. As a result, braces severely restrict the normal physiological activities of the spine, which may lead to disuse atrophy of the core muscle groups and reduce the effect of scoliosis correction on the patient's spine. Summary of the Invention

[0004] The purpose of this invention is to provide an upright scoliosis correction and fixation device, which aims to solve the problem that existing braces are often static and passive correction methods, unable to be dynamically adjusted according to changes in the patient's posture, and the corrective force is constant and cannot provide precise fine-tuning. As a result, the braces severely restrict the normal physiological activities of the spine, which may lead to disuse atrophy of the core muscle groups and reduce the scoliosis correction effect on the patient's spine.

The adjacent ends of the multiple support blocks are fixedly connected to the two sides of the two sliding seats respectively.

[0010] As a preferred embodiment of the present invention, it further includes multiple sets of buffer mechanisms, each set of buffer mechanisms comprising: A buffer shell is fixedly connected to one end of a buffer seat. A compression shell is slidably connected to the inner surface of the buffer shell. A sliding rod is fixedly connected to one end of the compression shell. A connecting pad is fixedly connected to the outer surface of the sliding rod. One end of the connecting pad is fixedly connected to one end of the fixed seat.

[0011] As a preferred embodiment of the present invention, each group of elastic components includes: A support shell is fixedly connected to the inner surface of a buffer shell. A compression rod is slidably connected to the inner surface of the support shell. One end of the compression rod is fixedly connected to the inner surface of the compression shell. A second spring is sleeved on the outer surface of the support shell.

[0012] As a preferred embodiment of the present invention, it further includes an adjustment mechanism, the adjustment mechanism comprising: A dual-axis motor is mounted on the inner surface of a support frame. The output ends of the dual-axis motor are movably connected through the upper and lower ends of the support frame, respectively. Both output ends of the dual-axis motor are fixedly connected with lead screws, and nuts are threaded onto the circumferential surfaces of the two lead screws. Two limiting rods are fixedly connected to the inner walls of the upper and lower sides of the housing.

The adjacent ends of the multiple limiting blocks and the two sides of the two nuts are fixedly connected respectively. An extension component is disposed on one side of the housing to provide support for the patient's neck and lower back.

[0013] As a preferred embodiment of the present invention, the extension component includes: Two telescopic seats are fixedly connected to the upper and lower ends of multiple limiting blocks respectively. The upper and lower ends of the two telescopic seats can move through the upper and lower inner walls of the housing. The outer surface of the two telescopic seats is provided with a base, and one end of the two telescopic seats is provided with a pad.

[0014] As a preferred embodiment of the present invention, a cover plate is provided on the inner surface of the housing, and two screws are threadedly connected to one end of the cover plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By sliding the adjusting shell along the outer surface of the adjusting plate, the extension length on the adjusting plate is adjusted so that the clamping pad can approach the preset corrective force application point on the side of the body. Final fine-tuning of the length is performed using the telescopic rod to ensure contact between the clamping pad and the body surface. When the clamping pad contacts the body surface and is subjected to pressure, the force is transmitted to the clamping shell, which then transmits the force to the internally slidably connected buffer seat, pushing the buffer seat to slide inwards. The sliding of the buffer seat causes the sliding groove and limiting post on it to move, forcing the two sliding seats fitted on the limiting post to slide towards each other. The movement of the sliding seats is transmitted to the connecting seat fixed on the fixed seat through the connecting rod hinged to them. This linkage mechanism converts the displacement of the buffer seat into an effective clamping force on the fixed seat. The operator can precisely adjust the point of application and angle of force in the anterior-posterior and lateral directions of the body according to the patient's specific scoliosis type and vertebral position, achieving a highly personalized and precise fit. Combined with the motor-driven longitudinal traction mechanism, the traction force can be dynamically adjusted, realizing a transformation from single static fixation to multi-dimensional dynamic correction, significantly improving the targeting and effectiveness of the correction.

[0016] 2. The inward sliding of the buffer seat simultaneously moves the buffer shell fixed to one end. Since the compression shell inside the buffer shell is connected to the fixed seat via a sliding rod and connecting pad, the movement of the buffer shell causes the compression shell to slide relative to the buffer shell. The compression shell pushes the compression rod fixed to it to slide within the support shell, compressing the second spring sleeved outside the support shell. The compression deformation of the second spring absorbs energy, producing a cushioning effect, keeping the pressure applied to the body gentle and adaptable to minor body movements, avoiding rigid impacts.

[0017] 3. By activating the dual-axis motor in the adjustment mechanism, the lead screws on both sides are driven to rotate synchronously. The nut, which is threaded with the lead screw, moves linearly under the constraint of the limit rod and limit block. The movement of the nut is transmitted to the outside of the housing through the telescopic seat fixed to it, which drives the base and support pad at its end to rise and fall, thereby adjusting the neck support pad to support the chin and / or occiput, and adjusting the support pad below the waist to provide appropriate support, thus achieving traction and support for the spine in the height direction.

The near ends of the multiple limiting blocks 17 are fixedly connected to the two ends of the two nuts 18 respectively. The extension component is located on one side of the housing 1 to provide support for the patient's neck and lower back.

[0039] In this embodiment: a dual-axis motor 14 serves as the power source for the adjustment mechanism, providing bidirectional rotational output to drive the lead screw 15. The lead screw 15 is driven to rotate by the dual-axis motor 14, converting the motor's rotational motion into the linear motion of the nut 18. The nut 18 is threadedly engaged with the lead screw 15, converting the rotational motion of the lead screw 15 into its own linear motion. The limiting rod 16 is fixed to the upper and lower inner walls of the housing 1, providing a linear sliding track for the limiting block 17. The limiting block 17 is fixedly connected to the nut 18 and slidably connected to the limiting rod 16, preventing the nut 18 from rotating with the lead screw 15 and constraining it to only move linearly. The telescopic seat 19 is fixedly connected to the upper end of the limiting block 17 and penetrates the housing 1 at the lower end.

It should be noted that the specific model of the dual-axis motor 14 used shall be selected by those skilled in the art, and the above-mentioned dual-axis motor 14 and other related technologies are all existing technologies and will not be elaborated in this solution.

[0040] Please refer to the details. Figure 7 The extension components include: Two telescopic seats 19 are fixedly connected to the upper and lower ends of multiple limiting blocks 17 respectively. The upper and lower ends of the two telescopic seats 19 can move through the upper and lower inner walls of the housing 1. The outer surface of the two telescopic seats 19 is provided with a base 3, and one end of the two telescopic seats 19 is provided with a support pad 4.

[0041] In this embodiment: the upper end of the telescopic seat 19 is fixedly connected to the limiting block 17, and the lower end penetrates the housing 1, which is used to transmit the linear movement of the nut 18 to the outside of the housing 1 and drive the support pad 4 to rise and fall.

The support pad 4 is set at the end of the telescopic seat 19 and directly contacts the back of the patient's neck or lower back to provide support and upward traction.

[0042] Please refer to the details. Figure 5 The inner surface of the housing 1 is provided with a cover plate 20, and one end of the cover plate 20 is threaded with two screws 10.

[0043] In this embodiment: the cover plate 20 is disposed on the inner surface of the housing 1 to close the internal space of the housing 1 and protect the internal mechanism, and the screw 10 is used to fix the cover plate 20 to the housing 1.

[0044] The working principle and usage process of this invention are as follows: The shell 1 is worn on the torso, allowing the lumbar support pad 2 to fit snugly against the waist for initial positioning. The dual-axis motor 14 is then activated, driving the lead screw 15 to rotate, which in turn causes the nut 18 and the fixed limiting block 17 to move linearly along the limiting rod 16. This movement is transmitted through the telescopic seat 19, driving the upper and lower support pads 4 to rise and fall, thereby adjusting the support height for the neck and waist, achieving longitudinal traction and support for the spine. The buckle 9 is then released, and the adjusting plate 7 is rotated to coarsely adjust the front-to-back angle of the lateral mechanism. Subsequently, the sliding adjustment shell 8 is used to fine-tune its extension length, and finally the telescopic rod 11 is used for fine length adjustment so that the clamping pad 13 is precisely close to the body side correction point. After the clamping pad 13 contacts the body surface, the pressure drives the buffer seat 21 to slide inward. The sliding pushes the two sliding seats 24 to move towards each other through the limiting post 28 inside. The linkage mechanism composed of the connecting rod 27 converts the movement into an effective clamping force on the fixed seat 25. The support block 37 slides in the support groove 36 to ensure stable movement. At the same time, the movement of the buffer seat 21 drives the buffer shell 29 to generate a relative displacement relative to the compression shell 33 fixed by the sliding rod 34, thereby compressing the second spring 32. The spring deformation absorbs energy and provides continuous and gentle buffer pressure to adapt to the slight movement of the body.
