Abstract
Description
Technical Field
[0001] This invention relates to the field of spinal shell detection technology, specifically a device and method for detecting abnormal spinal curvature. Background Technology
[0002] Scoliosis, commonly known as spinal curvature, is a three-dimensional deformity of the spine, including abnormalities in the coronal, sagittal, and axial planes. Common manifestations of spinal curvature include uneven shoulders and asymmetrical lumbar deformities. Therefore, in assessing whether a patient has symptoms of spinal curvature, in addition to X-ray or CT scans, manual assessment of the patient's physical condition can also be used to determine if the condition is present. However, in practice, X-ray and CT scans are expensive and take a long time to process. Furthermore, manual assessment, which relies primarily on subjective judgment of the tilt angle of the shoulders or lower back, is prone to significant errors. Since a tilt angle greater than 5-7 degrees generally indicates spinal curvature, manual assessment is not precise enough and prone to misdiagnosis. Therefore, a device and method for detecting spinal curvature abnormalities are needed to address these issues. Summary of the Invention

[0019] Please see Figures 1-6 A spinal curvature abnormality detection device includes: a support plate 1, with a mounting groove 2 on the surface of the support plate 1; an upper detection mechanism 3, which is disposed inside the mounting groove 2, the upper detection mechanism 3 including an upper mounting base 31, a first bidirectional screw 32 rotatably connected inside the upper mounting base 31, two symmetrically arranged side plates 33 threadedly connected to the outside of the first bidirectional screw 32, a support groove being formed inside the side plates 33, a compression spring 34 being fixedly connected to the top of the inner wall of the support groove, a pressure rod 35 being fixedly connected to the bottom of the compression spring 34, and a rubber wheel 36 being rotatably connected to the bottom of the pressure rod 35; The lower detection mechanism 4 is located inside the mounting groove 2 and below the upper detection mechanism 3. The lower detection mechanism 4 includes a lower mounting base 41. A second bidirectional screw 42 is rotatably connected inside the upper and lower mounting bases 41. Two symmetrically arranged vertical plates 43 are threadedly connected to the outside of the second bidirectional screw 42. A measuring shaft 44 is slidably connected to the outside of the vertical plates 43. A drive assembly 45 is provided outside the lower mounting base 41. The drive assembly 45 drives the measuring shaft 44 to move in the vertical direction to perform waist measurement. It should be noted that the first bidirectional screw 32 and the second bidirectional screw 42 are respectively provided with a rotation drive component, which can be a stepper motor, used to drive the first bidirectional screw 32 or the second bidirectional screw 42 to rotate.
[0020] Angle measuring mechanism 5, there are two sets, and they are respectively adapted to the upper detection mechanism 3 and the lower detection mechanism 4. Angle measuring mechanism 5 is used to measure the height difference between two rubber wheels 36 or to measure the height difference between two measuring shafts 44.
[0021] In this embodiment, the top end of the pressure rod 35 is slidably connected to the inner side of the support groove, and the specifications of the top end of the pressure rod 35 are adapted to the support groove. Under the cooperative support of the top end of the pressure rod 35 and the bottom of the inner wall of the support groove, the rubber wheel 36 can always maintain a stable connection with the side plate 33. The angle measuring mechanism 5 is set between the two pressure rods 35, and the side plate 33 is slidably connected to the inner side of the upper mounting base 31.
[0022] In this embodiment, the drive assembly 45 includes a sliding groove formed inside the two vertical plates 43. A vertical block 451 is slidably connected to the inner side of the sliding groove. A sliding cavity 452 is formed inside the vertical block 451. A sliding block 453 is slidably connected to the inner side of the sliding cavity 452. A cylinder 454 is fixedly installed on the outside of the lower mounting base 41. An angle measuring mechanism 5 is disposed between the two sliding blocks 453. A measuring shaft 44 is rotatably connected to the surface of the vertical block 451. A buffer spring 455 is fixedly connected between the bottom of the inner wall of the sliding cavity 452 and the vertical block 451.
[0023] In this embodiment, the angle measuring mechanism 5 includes a sleeve 51, with two symmetrically arranged sleeve rods 52 slidably connected to the inner side of the sleeve 51. An angle sensor 53 is fixedly installed on the top surface of the sleeve 51. The vertical plate 43 is slidably connected to the inner side of the lower mounting base 41. In one set of angle measuring mechanisms 5, the two sleeve rods 52 are respectively fixedly connected to two pressure rods 35. In another set of angle measuring mechanisms 5, the two sleeve rods 52 are respectively fixedly connected to two sliding blocks 453. In the angle measuring mechanism 5 located outside the sliding blocks 453, the sleeve 51 is fixedly connected to the top of the telescopic end of the cylinder 454. The tilt state of the shoulders and waist of the person being measured can be detected respectively, thereby facilitating the determination of their degree of bending.
[0024] It should be further explained that the sleeve 51 has a groove inside, and an opening at its end. The size of the opening is smaller than the size of the groove opening. The head of the sleeve rod 52 slides inside the groove, and the size of the head matches the size of the groove opening, preventing it from exiting from the opening which is smaller than its size. This ensures that the sleeve rod 52 can never be separated from the sleeve 51, maintaining a stable connection between the two. In the initial state, the telescopic end of the cylinder 454 is extended, and under the support of the cylinder 454, the vertical block 451 is located at the top of the groove, and the sliding block 453 is located at the top of the sliding cavity 452. In this state, the buffer spring 455 is in its normal state.
[0025] In this embodiment, an adjustment mechanism 6 is provided on the outside of the support plate 1. The adjustment mechanism 6 includes a cavity opened inside the support plate 1. Two pulleys 61 are rotatably connected inside the cavity. A transmission belt 62 is driven between the two pulleys 61. Two winding wheels 63 are rotatably connected inside the cavity. Two lifting ropes 66 are wound around the outside of the two winding wheels 63 respectively. A control component 64 is provided between the pulleys 61 and the winding wheels 63. There are two control components 64, which correspond to the two pulleys 61 and the two winding wheels 63 respectively. They can provide driving force for the rotation of the two winding wheels 63 at the same time. A limiting component 65 is provided on the outside of the upper mounting base 31 and the lower mounting base 41 respectively.
[0026] It should be further explained that a rotation drive component is provided on the outside of one pulley 61. This drive component can be a stepper motor, which is used to drive the pulley 61 to rotate. Under the transmission action of the transmission belt 62, when the pulley 61 rotates, it can drive the other pulley 61 to rotate synchronously.
[0027] In this embodiment, the control component 64 includes a connecting shaft 641 fixedly connected to the outside of the take-up reel 63. A first toothed plate 642 is slidably connected to the outside of the connecting shaft 641. A plurality of circularly distributed limiting grooves 644 are formed on the surface of the connecting shaft 641. A limiting block 643 adapted to the limiting groove 644 is fixedly connected to the inner side of the first toothed plate 642. A convex ring 645 is fixedly connected to the outside of the connecting shaft 641. A connecting spring 646 is fixedly connected between the convex ring 645 and the first toothed plate 642. The connecting spring 646 is sleeved on the outside of the connecting shaft 641, and the movement of the first toothed plate 642 can smoothly drive the connecting spring 646 to compress. A second toothed plate 647 is fixedly connected to the outside of the pulley 61.
[0028] In this embodiment, the first toothed plate 642 meshes with the second toothed plate 647, and the meshing surfaces of the first toothed plate 642 and the second toothed plate 647 are provided with guide slopes 648. The bottom ends of the two lifting ropes 66 are fixedly connected to the upper mounting base 31 and the lower mounting base 41, respectively. When the two winding wheels 63 rotate to wind up the lifting ropes 66, the lifting ropes 66 pull the upper mounting base 31 and the lower mounting base 41 to move upward.
[0029] It should be further explained that, under normal operating conditions, under the pressure of the connecting spring 646, the relative sliding frictional resistance between the guide slope 648 on the first toothed plate 642 and the guide slope 648 on the second toothed plate 647 is greater than the motion resistance of the winding wheel 63 when winding or unwinding the suspension rope 66. When the winding of the suspension rope 66 is restricted, the winding wheel 63 cannot rotate under the restriction of the suspension rope 66, thus preventing the second toothed plate 647 from rotating. At this time, under the guidance of the guide slope 648, the first toothed plate 642 will overcome the sliding resistance between itself and the second toothed plate 647 and slide axially along the surface of the connecting shaft 641, allowing relative sliding to occur between the second toothed plate 647 and the first toothed plate 642.
[0030] In this embodiment, the limiting component 65 includes an electric telescopic rod 651. A pull plate 652 is fixedly connected to the top of the telescopic end of the electric telescopic rod 651. Two symmetrically arranged linkage plates 653 are rotatably connected to the outside of the pull plate 652. A support plate 654 is rotatably connected to the outside of the linkage plate 653. The inner wall of the mounting groove 2 is provided with symmetrical vertical grooves 655. The inner wall of the vertical grooves 655 is provided with a plurality of slots 656 corresponding to the support plate 654. In one group of limiting components 65, the pull plate 652 and the support plate 654 are slidably connected to the inner side of the upper mounting base 31, and the electric telescopic rod 651 in this group is fixedly connected to the inner wall of the upper mounting base 31. In another group of limiting components 65, the pull plate 652 and the support plate 654 are slidably connected to the inner side of the lower mounting base 41, and the electric telescopic rod 651 in this group is fixedly connected to the inner wall of the lower mounting base 41.
[0031] More specifically, the upper mounting base 31 and the lower mounting base 41 are respectively provided with longitudinal grooves and transverse grooves that are adapted to the pull plate 652 and the support plate 654. The pull plate 652 is slidably connected to the inner side of the longitudinal groove, and under the restriction of the longitudinal groove, the pull plate 652 can only move in the vertical direction. The support plate 654 is slidably connected to the inner side of the transverse groove, and under the restriction of the transverse groove, the support plate 654 can only move in the vertical direction. When the telescopic end of the electric telescopic rod 651 extends or retracts, the pull plate 652 can move upward or downward, thereby driving the two support plates 654 to move away from or towards each other. Furthermore, when the pull plate 652 moves to the lower limit position, the support plate 654 still cannot exit from the interior of the vertical groove 655, thus ensuring the stability of the vertical movement of the upper mounting base 31 and the lower mounting base 41.
[0032] It should be further noted that the spinal curvature abnormality detection device also includes a compatible detection system, which includes: The measuring unit, namely the angle sensor 53, is used to measure the tilt state of the subject's shoulders and waist. The analysis unit is used to receive and analyze the data measured by the measurement unit and determine the maximum angle value obtained during the measurement process. The display unit receives and displays the maximum angle value obtained from the analysis by the analysis unit, making it easier to determine the final measurement result more intuitively.
[0033] A method for detecting spinal curvature abnormalities, applied to the aforementioned spinal curvature abnormality detection device, includes the following steps: S1. Height adjustment: The positions of the upper mounting base 31 and the lower mounting base 41 are adjusted by the adjustment mechanism 6 to accommodate the height of the person being tested; S2, Position Adjustment: The distance between the two rubber wheels 36 and the distance between the two measuring shafts 44 are adjusted by the first bidirectional screw 32 and the second bidirectional screw 42 respectively, to adapt to the shoulder width and waist width of the person to be tested; S3. Detection: The first bidirectional screw 32 drives the two rubber wheels 36 to move away from each other along the shoulders of the person to be tested, and the cylinder 454 drives the measuring shaft 44 to move downward. During this movement, the angle sensor 53 measures the tilt angle of the sleeve 51 to obtain the tilt status data of the shoulders and waist.
[0034] Working principle: Before use, when the operator needs to adjust the upper mounting base 31 or the lower mounting base 41 upward, the operator starts the corresponding electric telescopic rod 651 by controlling it to retract its telescopic end and drive the pull plate 652 to move downward. Under the transmission action of the linkage plate 653, the two side support plates 654 move synchronously and approach each other, so that they can be withdrawn from the inside of the slot 656, so that the vertical movement of the upper mounting base 31 or the lower mounting base 41 is no longer restricted. At this time, under the transmission action of the control component 64, the rotation of the pulley 61 can drive the winding wheel 63 to rotate, and there are three motion states: In the first state, the movement restrictions of the upper mounting base 31 and the lower mounting base 41 are both released during the upward movement. In this state, the winding of the hoisting rope 66 is not restricted. At this time, the rotation of the winding wheel 63 will wind up the hoisting rope 66, causing its end to pull the upper mounting base 31 and the lower mounting base 41 to move upward. In the second state, the upward movement occurs when the movement restriction of one of the upper mounting base 31 and the lower mounting base 41 is released. In this state, when the winding wheel 63 is winding, the released movement restriction will not restrict the winding of the lifting rope 66, so that when the corresponding winding wheel 63 rotates, it will wind the lifting rope 66, allowing its end to pull the upper mounting base 31 or the lower mounting base 41 below it to move upward. However, when the movement restriction is not released, the lifting rope 66 connected to it cannot be wound, so the rotation of the corresponding winding wheel 63 is restricted, resulting in relative rotation between the first toothed plate 642 and the second toothed plate 647, which can satisfy the upward position adjustment of one of the upper mounting base 31 and the lower mounting base 41. The third state is the descent when the movement restrictions of the upper mounting base 31 and the lower mounting base 41 are both released. In this state, when the winding wheel 63 rotates, the two sets of lifting ropes 66 can be released synchronously. At this time, under the action of their own weight, the upper mounting base 31 and the lower mounting base 41 can move downward synchronously. In the fourth state, the descent occurs when the movement restriction of one of the upper mounting base 31 and the lower mounting base 41 is released. In this state, when the winding wheel 63 rotates, the two sets of lifting ropes 66 can be released synchronously. However, the upper mounting base 31 or the lower mounting base 41, which is not released from its restriction, cannot move downward, causing the lifting ropes 66 connected to it to become loose. Therefore, after one of the downward positions is adjusted, the movement of both needs to be restricted, and the winding wheel 63 is driven to rotate in the opposite direction to wind up the lifting ropes 66. At this time, the loose lifting ropes 66 can be wound up, while the taut lifting ropes 66 remain in their original state.
[0035] When the position of the rubber wheel 36 is adjusted, the first bidirectional screw 32 drives the two side plates 33 to move synchronously in opposite directions, so that the position of the rubber wheel 36 located below the two side plates 33 is at the end of the subject's shoulder near the neck. During the height adjustment of the upper mounting base 31, the pressure rod 35 below the two side plates 33 can extend into the interior of the side plates 33 and compress the compression spring 34 inside. When adjusting the position of the measuring shaft 44, the two vertical plates 43 on both sides are driven to move synchronously in opposite directions by the second bidirectional screw 42, and the measuring shaft 44 located outside the two vertical plates 43 can be closely attached to the waist sides of the subject. During the measurement process: When measuring the shoulder tilt, the first bidirectional screw 32 drives the two side plates 33 to move away from each other. At this time, under the action of the compression spring 34, the bottom of the rubber wheel 36 is always in contact with the shoulder of the person being tested. During this process, when the shoulder is tilted, there will be a distance difference between the downward movement distance of one side of the rubber wheel 36 and the other side, so that the two rubber wheels 36 are no longer on the same horizontal plane. As the two side plates 33 move away from each other, the two sleeve rods 52 will gradually withdraw from the sleeve 51. When the two rubber wheels 36 are no longer on the same horizontal plane, the sleeve rods 52 will rotate accordingly, so that the angle sensor 53 can measure the tilt angle of the shoulder in real time. When measuring the lumbar tilt, the cylinder 454 is activated, causing its telescopic end to retract. This causes the sleeve 51, the rod 52, the sliding block 453, and the vertical block 451 to move downwards synchronously. When one measuring shaft 44 moves to contact the protruding part of the hip bone, the downward movement of the measuring shaft 44 in contact with it is restricted by the limiting effect of the protruding part, preventing the vertical block 451 from moving downwards. At this time, the continued retraction of the telescopic end of the cylinder 454 will cause the sliding block 453 to continue moving downwards, thereby compressing the buffer spring 455 and causing relative sliding between it and the vertical block 451. The unobstructed measuring shaft 44 continues to move downwards, creating a height difference between the two sliding blocks 453, causing the sleeve 51 and the rod 52 to rotate and tilt. At this time, the lumbar condition of the subject can be measured by the angle sensor 53.
