Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of spinal curvature detection, and in particular to a spinal curvature detection device for spinal surgery. Background Art
[0002] The examination method for scoliosis is mainly to confirm the diagnosis from the appearance of the spine as well as physical examination and imaging examination of the spine. The appearance of scoliosis can be mainly checked through the bending test, that is, the patient naturally turns his back to the examiner, puts his feet together, lets both upper limbs droop naturally, and looks up and forward. The examiner will find that the patient's shoulder plane is asymmetrical and one side of the scapula bulges backwards, and the distance from the upper limb to the trunk is unequal, with one side higher than the other. At the same time, it can be seen that the midpoint of the occipital region and the midpoint of the mid-buttocks are not on the same vertical line, and there is a tilted pelvis or unequal length of the lower limbs. The physical examination is mainly an examination of the symmetry of the trunk, that is, the patient can stand upright and be observed from behind, and can be measured with a vertical line or a plumb line. Under normal circumstances, the vertical line should pass through the mid-buttocks groove. If the vertical line moves to one side of the mid-buttocks groove, scoliosis is considered and a film examination is required. Imaging X-ray examination will show obvious scoliosis deformity.
[0003] The defects of a spinal curvature detection device for spinal surgery in the prior art are:
[0004] 1. Patent document CN109464148B discloses, "A device and system for measuring spinal curvature, the device comprising: a measuring device body, a processor, a memory and a display, the display, the processor and the memory are respectively connected to the measuring device body, and the display and the memory are respectively connected to the processor; the memory is used to obtain an image of the spine to be detected; the processor inputs the image into a pre-trained neural network model to obtain a connection response diagram for characterizing the upper and lower line positions of each vertebral body and the coordinate positions of all corner points; the processor obtains a first connection diagram and a second connection diagram based on the coordinate positions of all corner points; the processor obtains a first connection diagram and a second connection diagram based on the connection response diagram, the first connection diagram, the second connection diagram, and ... and the global optimal criterion, obtain the true upper edge line and the true lower edge line of each vertebral body; the processor obtains and sends the Cobb angle value of the spine to be tested to the display based on the true upper edge line and the true lower edge line of each vertebral body, thereby improving the measurement accuracy". However, the device and system for measuring spinal curvature do not explain how the patient needs to be tested. When the patient needs to stand for the test, it is inconvenient to test the patient in a wheelchair or with limited mobility. If the patient needs to lie down or lie on his stomach for the test, the patient needs to move to the top of the fixed device. At this time, the medical staff needs to lift the patient with limited mobility onto the device, which is very inconvenient, making the operation of the device time-consuming and laborious, and reducing the detection efficiency of the device.
[0005] 2. Patent document CN109223032B discloses, "A method for detecting spinal deformity by three-dimensional ultrasonic imaging, comprising the following steps: S1, obtaining a three-dimensional image of the spine using a three-dimensional ultrasonic imaging system; S2, obtaining spinal axial rotation information through the three-dimensional image of the spine; S3, using the spinal axial rotation information to make corresponding image adjustments to the three-dimensional image of the spine; S4, projecting the adjusted three-dimensional image of the spine into the coronal plane and / or sagittal plane to obtain projections of the coronal plane and / or sagittal plane; S5, calculating spinal deformation data through the projections of the coronal plane or sagittal plane. The present invention obtains a three-dimensional image through a three-dimensional ultrasonic imaging system, obtains the rotation of the main body of the spine in the data of the three-dimensional image by analyzing the rotation information and image information of each two-dimensional ultrasonic image, and estimates the rotation center of each two-dimensional image through the statistical information of the spine. This method can more accurately measure the deformation angle of the spine in each plane", but when the method for detecting spinal deformity by three-dimensional ultrasonic imaging is used to detect patients, it is necessary for the device to be equipped with various large auxiliary equipment such as an ultrasonic system and an imaging system, which greatly increases the use cost of the device, and the device is not convenient to use.
[0006] 3. Patent document CN109785297B discloses, "A method and device for detecting scoliosis, comprising: scanning a subject's back with a scanner to obtain a three-dimensional back image, generating a three-dimensional point model based on the three-dimensional back image; connecting the end points of the spine transverse direction according to the three-dimensional point model to form a transverse curve; fitting the midline of the subject's back according to the three-dimensional point model; connecting the highest points of each transverse curve at a preset distance on both sides of the midline to form a straight line, calculating the line-surface angle between each straight line and the horizontal plane; taking the largest line-surface angle as the trunk inclination angle, and the trunk The tilt angle is used to reflect the degree of asymmetry of the back spine of the subject. Under non-X-ray radiation-free conditions, the scoliosis condition of the subject can be obtained by identifying and analyzing the images collected by the scanner, avoiding the errors caused by traditional physical tests and having high objectivity and accuracy. However, this scoliosis detection method and device requires the patient to move forward during the detection. When the patient has difficulty in moving, there are no better protective measures, and the patient with difficulty in moving cannot be protected and fixed, which limits the use of the device and makes the device not convenient and safe to use.

Patent document CN103110296B discloses, "An experimental bed for automatically controlling mechanical properties of a system, comprising a mattress and a bed frame, wherein the mattress is composed of a bed core, a fabric composite layer, a latex sponge cushioning layer, and a spring base plate, wherein the bed core is composed of evenly arranged independent pocket springs, which are independently fixed on the spring base plate and provided with a linear displacement sensor; the mattress is set with an adjustable comfort zone for detecting changes in the morphology of the human spine, wherein the spring base plate of the zone is composed of a plurality of independent small spring base plates, each of which is used to support two horizontal rows of independent pocket springs. Springs are installed; a linear permanent magnet reciprocating engine is respectively arranged directly under each small spring base plate. The present invention transmits the collected information of the compression amount of the bagged springs to the data processor through the information collector to obtain the amount of depression of the human-bed interface. "The quantitative study of the interface shape and interface pressure between the human and the bed in the real sleeping position and the natural lying position is realized." However, the experimental bed for the mechanical properties of this automatic control system is relatively bulky. When the device needs to be moved, it needs to be aligned by external force for transportation. In addition, the device itself is difficult to disassemble and fold, which makes transportation inconvenient, the device is inconvenient to move, and the portability is not high.

[0043] Working principle: 1. Through the setting of the load-bearing motor 11, the load-bearing gear 12 and the rack 13, the rack 13 is in an arc shape, and the center of the circle corresponds to the center of the circle of the main rotating shaft 4. The load-bearing gear 12 can be driven to rotate by the work of the load-bearing motor 11.

[0044] 2. Through the arrangement of the servo motor 14, the rotating angle plate 16 and the varistor 21, the rotating angle plate 16 can be driven by the servo motor 14 to rotate and adjust the angle. When the patient uses the device for measurement, the patient's main trunk lies on the rotating angle plate 16. When the rotating angle plate 16 is pressed, the pressure spring 17 is compressed. When the pressure spring 17 is compressed, the conductive plate 20 touches the varistor 21. When the conductive plate 20 touches the varistor 21, the resistance of the varistor 21 decreases, and the conductive plate 22 conducts electricity. When the conductive plate 22 conducts electricity, the servo motor 14 works to drive the rotating angle plate 16 to rotate. When the rotating angle plate 16 moves downward, the conductive plate 22 is electrically conductive. When it rotates to a certain angle, the patient's spine reaches its maximum curvature. At this time, the patient's main trunk no longer bends downward, the rotating angle plate 16 is no longer under pressure, and the servo motor 14 no longer works to drive the rotating angle plate 16 to rotate. At this time, the rotation angle of the rotating angle plate 16 is the patient's maximum spine curvature. The rotation angle of the rotating angle plate 16 can be measured to detect the patient's maximum spine curvature. No additional searchlight equipment is needed to perform searchlight detection on the patient's spine, which can greatly reduce the production and purchase cost of the device. The measurement method is simple, and the measurement structure is stable and standard, which reduces the cost of the device itself and improves the functionality and ease of use of the device.
[0045] 3. By fixing the support block 31, the pedal 34 and the elastic strap 36, when the support plate 8 is in a vertical state, the patient stands on the pedal 34, and then the support plate 8 is rotated. The support plate 8 drives the pedal 34 to rotate together, which can facilitate the patient's use of the device. When the patient lies on the device and the rotating angle plate 16 is rotated downward, the elastic strap 36 is tied to the patient's legs, and the clamp head 37 is clamped in the buckle groove 38. The elastic strap 36 can fix the patient's legs, which can prevent the patient's incorrect body shape or unstable posture from affecting the measurement results, thereby improving the convenience and safety of the device.
