Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a method and device for scoliosis profiling. Background Art

[0002] Scoliosis is a three-dimensional deformity of the spine, including abnormal sequences in the coronal, sagittal and axial planes, and is often accompanied by thoracic deformity, pelvic rotational tilt deformity, and paravertebral ligament and muscle abnormalities. Scoliosis can seriously affect the patient's appearance and visceral function, and can be life-threatening for severe patients. For mild scoliosis, such as a scoliosis angle of less than 20°, observation and regular follow-up are often sufficient. Severe cases, such as a scoliosis angle greater than 45°, require surgical treatment. Patients with a scoliosis angle between 20° and 45° can be treated with orthopedic braces and regular follow-up, which can often prevent the continued progression of scoliosis to a certain extent and avoid surgical treatment.

[0003] At present, when a scoliotic spine is corrected, a scoliosis orthosis is usually used. It is a medical auxiliary device that is currently used more frequently to treat scoliosis. Before making the scoliosis orthosis, the patient's scoliosis needs to be molded. In the prior art, plaster molding is used. This method not only has complicated molding steps and low molding efficiency, but also has low molding accuracy. For this reason, the prior art, such as the Chinese patent with announcement number CN209253247U, discloses a scoliosis mold frame, including a bottom plate, the four side edges of the top of the bottom plate are A fixing rod is fixed vertically, and a plurality of groups of parallel top frames are provided at the top ends of the four fixing rods. A traction device is provided at the bottom end of the middle top frame, and the traction device includes a traction display. A second lock buckle is sleeved at the bottom end of the traction display, a traction line is fixed on the second lock buckle, and a traction frame is fixed at the lower end of the traction line; cross bars are connected to the outer walls between the adjacent two fixing rods, and lifting mechanisms are provided at both ends of the cross bars, and the lifting mechanism includes a first lock buckle, and the accuracy of molding is improved through the cooperation of the pressure plate and the pushing rod.

[0004] However, the applicant has discovered that, when taking a mold of a scoliosis patient, the prior art such as the one mentioned above requires manually placing a number of pressure plates close to the measured position on the patient's body surface. However, factors such as the patient's inadvertent movements when standing and the movement of the patient's spine during traction will cause the patient's body to move, thereby affecting the close fit and misalignment of the pressure plates, and even causing the entire pressure point to be invalidated. It is necessary to redefine the point and adjust the pressure plate, which is time-consuming and labor-intensive. In addition, when the patient's body moves, the pressure data around the measured point also has reference significance. The above-mentioned device is difficult to achieve follow-up detection, resulting in poor molding accuracy and an inconvenient molding process. Summary of the invention

[0005] The present invention discloses a scoliosis shaping method and device, which solve the technical problems in the above-mentioned background technology.

[0006] A method for scoliosis profiling, comprising the following steps:

[0007] S1: The patient stands on the surface of the force plate on the base and is in a normal standing posture. At this time, the patient stands without being affected by external forces.

DETAILED DESCRIPTION

[0035] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0036] The present invention discloses a method for shaping scoliosis, comprising the following steps:

[0037] S1: The patient stands on the surface of the force plate 13 on the base 1 and is in a normal standing posture. At this time, the patient stands without being acted upon by external forces. According to the patient's height and the position of the mold, the sliding sleeve 22 is operated to move longitudinally, and then the adjusting rod 23 is moved horizontally to make the measuring plate 231 close to the measured position of the patient's body;

[0038] S2: Apply pressure at any position of the patient's spine through the pressure sensing block 232, and simulate the pressure position and depth of the scoliosis brace to be made later during the molding process. At this time, the position of each measuring plate 231 is determined by the distance sensor 221, and the patient's body movement will not affect the misalignment and invalidation of the measuring plate 231 points;

[0039] S3: stretching the patient. During the stretching process, the movement of the spine prompts the patient to adjust his posture to adapt to the state of the spine after stretching. The change in posture will lead to the redistribution of the center of gravity of the body weight, thereby affecting the pressure change of the feet on the force plate 13. The value of the pressure sensor in the force plate 13 changes to start the activity of the driving component;

[0040] S4: The driving assembly drives the connecting rod 2 to move horizontally in the slide groove 21, thereby synchronously measuring the measured point position and surrounding pressure data during the patient's stretching process. The moving path of the measuring plate 231 can be guided by the arbitrarily bent universal tube 25, which is convenient for setting the moving path in advance. After the patient is fully stretched, the pressure depth of each part of the patient's spine is detected again;

[0041] S5: The pressure sensor block 232 is used to detect the spinal pressure depth detection data of the patient in a normal standing state without external force, during stretching, and after stretching, and the data are integrated to synthesize the final spinal orthotic sculpture model, and the orthosis is 3D printed for the patient to wear.

[0042] Through the above steps, it is ensured that the patient can perform real-time pressure depth detection in the normal standing state, during the stretching process and after stretching, which helps to match the patient's spinal pressure changes during the stretching process and improve the accuracy of scoliosis diagnosis.

[0043] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a scoliosis shaping device, including a base 1, a support frame 11 and a top frame 12, a plurality of connecting rods 2 are arranged between the base 1 and the top frame 12, the lower end of the support frame 11 is fixed to the top of the base 1, and the upper end of the support frame 11 is fixed to the bottom of the top frame 12, and the support frame 11 can be fixed to the base 1 and the top frame 12 by welding, bolting, etc., and the inner wall of the top frame 12 is also provided with a cross bar for connecting the traction frame, and the traction frame can be directly hung on the cross bar for stretching the body of the scoliosis patient, and also includes a plurality of adjusting rods 23, the number of adjusting rods 23 matches the number of connecting rods 2, the surface of a single connecting rod 2 can match one or more adjusting rods 23, the number of adjusting rods 23 on the surface of a single connecting rod 2 is determined according to the detection points at different positions of the patient, and the adjusting rods 23 are arranged on the surface of the connecting rod 2. The adjusting rod 2 is connected to the connecting rod 2 through the sliding sleeve 22, the adjusting rod 23 slides horizontally in the sliding sleeve 22, and the connecting rod 2 slides longitudinally in the sliding sleeve 22, a measuring plate 231 is arranged at one end of the adjusting rod 23, a distance sensor 221 adapted to the measuring plate 231 is installed on the surface of the sliding sleeve 22, the distance between the distance sensor 221 and the measuring plate 231 is sensed by the distance sensor 221, and the positioning effect of the measuring plate 231 is ensured, a pressure sensing block 232 is installed on the surface of the measuring plate 231, a signal line 236 is arranged at one end of the adjusting rod 23 away from the measuring plate 231, the signal line 236 is electrically connected to the pressure sensing block 232, and one end of the signal line 236 away from the adjusting rod 23 is connected to an external signal receiving and processing device for transmitting pressure sensing values, a sliding groove 21 is provided on the top of the base 1, and the connecting rod 2 is slidably connected to the inner wall of the sliding groove 21;

[0044] A connecting assembly is arranged on the surface of the adjusting rod 23. The connecting assembly includes a collar 24 rotatably connected to the surface of the adjusting rod 23. A plurality of rollers 241 are rotatably connected in the collar 24. A universal tube 25 is passed through the collar 24. The universal tube 25 is a plastic metal bendable tube, such as carbon steel, aluminum alloy and other materials, which can be bent into any arc shape and maintained. It is a prior art and will not be described in detail here. The two ends of the universal tube 25 are respectively passed through the collars 24 on the surfaces of adjacent adjusting rods 23. Furthermore, a clamp or a fixing hoop can be provided on the surface of the universal tube 25 for being fixedly connected to the collar 24, so as to fix the universal tube 25 on one of the surfaces of the collar 24. A driving assembly is arranged in the base 1, and is used to drive the connecting rod 2 to reciprocate along the slide groove 21. When one of the connecting rods 2 moves along the slide groove 21, the adjusting rod 23 moves along the path of the universal tube 25 in the collar 24.

[0045] Specifically, by setting the sliding sleeve 22, it is convenient to adjust the height of the adjusting rod 23 on the surface of the connecting rod 2, and the distance between the measuring plate 231 and the sliding sleeve 22, so as to adjust the spinal detection point according to patients of different heights and body shapes. Among them, due to the setting of the distance sensor 221, when the patient is in a normal standing state without external force and the measuring plate 231 is pressed against the surface of the patient's body, the distance between the measuring plate 231 and the sliding sleeve 22 at this time is recorded, and then after the measuring plate 231 is adjusted or misplaced due to the patient's own activities, the distance sensor 221 can be used to adjust the spinal detection point according to the patient's height and body shape. The measuring plate 231 is returned to the initial position, so that the patient can more accurately match the standing posture of the initial position, ensure the consistency of the test data, and avoid invalidation of the data of all test points due to the patient's activities. A buzzer or a prompt light can be set on the surface of the sliding sleeve 22. After the distance sensor 221 records the position of the measuring plate 231 for the first time and moves the measuring plate 231, the measuring plate 231 is moved to the initial position again and matched with the distance of the distance sensor 221. The buzzer or the prompt light can be used to give a sound and light prompt, thereby improving the operation efficiency.

[0046] Furthermore, through the coordinated setting of the connecting component and the driving component, when the patient is stretched, the driving component drives the connecting rod 2 to slide in the corresponding direction in the slide groove 21, thereby driving the adjusting rod 23 on the surface of the connecting rod 2 to move. Due to the coordinated setting of the universal tube 25 and the collar 24, the adjusting rod 23 will move along the curved path of the universal tube 25, thereby adjusting the moving path of the measuring plate 231. The curved path of the universal tube 25 is set according to the patient's detection position before the detection, and then during the patient's stretching, the measuring plate 231 is automatically moved along the path, and the pressure depth of the muscle tissue or spine around the measured point is detected. The surface of the universal tube 25 is set to a smooth epidermis, and a roller 241 is provided in the collar 24. The roller 241 contacts the surface of the universal tube 25 to reduce friction, thereby improving the convenience of movement of the collar 24 on the surface of the universal tube 25.

[0047] It is worth noting that the universal tube 25 can be set not only between adjacent adjustment rods 23, but also between multiple adjustment rods 23. For example, for three or four adjacent adjustment rods 23, the universal tube 25 passes through the rings 24 on the surfaces of the three or four adjustment rods 23 respectively. When the universal tube 25 is relatively long, it can be fixed and supported by a supporting structure to improve its guiding accuracy. The universal tube 25 is bent into a certain arc and shape in advance. In this way, when the patient is stretching, two or more adjustment rods 23 can be moved at the same time to synchronize the position adjustment of the measuring plate 231. No additional manual adjustment is required, thereby improving the detection efficiency.

[0048] like Figure 4 As shown, in the present embodiment, a connecting block 233 is fixedly connected to one side of the measuring plate 231 close to the adjusting rod 23, the connecting block 233 is in a "U" shape, and the two arm ends of the connecting block 233 are hinged on the surface of the adjusting rod 23, the connecting block 233 is connected to the adjusting rod 23 through a torsion spring 234, the torsion spring 234 is arranged on the hinge axis between the two arm ends of the connecting block 233 and the adjusting rod 23, the two ends of the torsion spring 234 are respectively fixedly connected to the connecting block 233 and the adjusting rod 23, an active ball 235 is movably connected to one end of the adjusting rod 23 close to the measuring plate 231, a ball and socket interface is arranged at the end of the adjusting rod 23, the active ball 235 is universally connected in the ball and socket interface and can roll at will, and the active ball 235 is located between the adjusting rod 23 and the measuring plate 231.

[0049] Specifically, through the setting of the movable ball 235, when the adjusting rod 23 follows the connecting rod 2 to move laterally and the ring 24 slides along the surface of the universal tube 25, the measuring plate 231 attached to the surface of the patient's skin will be simultaneously subjected to the lateral force. Due to the friction between the measuring plate 231 and the skin, when subjected to the lateral force, the connecting block 233 on one side of the measuring plate 231 will rotate in the opposite direction on the surface of the adjusting rod 23 and compress the torsion spring 234, thereby exposing the movable ball 235 at the end of the adjusting rod 23, so that the movable ball 235 contacts the skin during the movement, and the rolling of the movable ball 235 reduces the friction between the skin and the skin, thereby avoiding discomfort to the patient. Accordingly, rollers can be set on both sides of the measuring plate 231. After the measuring plate 231 rotates to one side, the rollers contact the skin, reducing sliding friction and increasing rolling friction, thereby improving the comfort of the patient.

[0050] Further, such as Figure 5 As shown, in this embodiment, the surface of the tube body of the universal tube 25 is bent into an arc, and the arc is bent in a direction away from the center of the base 1. The arc bending area is before the terminal position where the measuring plate 231 needs to move, that is, before the adjusting rod 23 moves to the terminal position. When the collar 24 passes through the arc bending position, it will drive the adjusting rod 23 to move a certain distance in the direction away from the patient, thereby causing the movable ball 235 to leave the patient's skin surface. The measuring plate 231, which is no longer blocked by the skin, returns to its original position under the action of the rebound force of the torsion spring 234. Subsequently, after passing through the arc bending area, the measuring plate 231 can be re-attached to the patient's skin surface, thereby facilitating the pressure sensing block 232 to reset and contact the skin and detect the pressure depth.

[0051] like Figure 6 As shown, in the present embodiment, the driving assembly includes a toothed disc 3, a circular groove is provided inside the base 1, the toothed disc 3 is rotatably connected to the center of the circular groove, and a motor 31 is installed at the bottom of the base 1, the motor 31 is a servo motor, the output end of the motor 31 passes through the base 1, and is fixedly connected to the toothed disc 3. When the motor 31 outputs, the toothed disc 3 can be driven to rotate, a force disk 13 is provided on the top of the base 1, a pressure sensor is provided in the force disk 13, the pressure sensor is electrically connected to the motor 31, a controller is provided in the motor 31, the pressure sensor is electrically connected to the controller, and the controller is electrically connected to the motor 31. When the pressure sensor in the force disk 13 senses a change in the pressure of the patient's feet, the signal is transmitted to the controller, and the motor 31 is controlled by the controller to rotate, thereby driving the toothed disc 3 to rotate, and a clutch assembly is provided between the toothed disc 3 and the connecting rod 2.

[0052] Further, such as Figure 6 and Figure 7As shown, in this embodiment, the clutch assembly includes a plurality of connecting rods 33 slidably connected to the base 1, the number of the connecting rods 33 corresponds to the number of the connecting rods 2, one end of the connecting rod 33 is fixedly connected to a positioning block 331, the inner wall of the circular groove is provided with a toothed ring 32, and both sides of the positioning block 331 are respectively provided with tooth grooves adapted to the toothed disc 3 and the toothed ring 32. Correspondingly, when the positioning block 331 is fitted with the toothed disc 3, the tooth groove is meshed with the toothed disc 3, and then the positioning block 331 and the connecting rod 33 can be driven to move by the rotation of the toothed disc 3, and when the positioning block 331 is disengaged from the toothed disc 3 and is engaged with the toothed ring When 32 is fitted, the tooth groove meshes with the gear ring 32, thereby fixing the position of the positioning block 331 and the connecting rod 33, so that the connecting rod 33 no longer moves, and the top of the connecting rod 33 is fixedly connected to the electric push rod 332, and the output end of the electric push rod 332 is rotatably connected to the guide wheel 333, and the inner wall of the base 1 is fixedly connected to the guide rail 334 adapted to the guide wheel 333, and the guide wheel 333 is guided and connected to the guide rail 334, and the guide wheel 333 can roll along the guide rail 334, and the end of the connecting rod 33 away from the positioning block 331 is connected to the connecting rod 2, and the pressure sensor is electrically connected to the electric push rod 332.

[0053] Specifically, when the pressure sensor in the force disk 13 senses the pressure change of the patient's feet due to stretching, the pressure sensor transmits the signal to the electric push rod 332 and the motor 31, and the output end of the electric push rod 332 extends. Since the guide wheel 333 is engaged with the surface of the guide rail 334, the output of the electric push rod 332 will push the connecting rod 33 in the opposite direction, so that the connecting rod 33 drives the positioning block 331 at one end to move to contact the surface of the toothed disk 3, and the tooth groove on the surface of the positioning block 331 meshes with the toothed disk 3, directly connecting the toothed disk 3, the connecting rod 33 and the connecting rod 2. At this time, through the output of the motor 31, The toothed disc 3 is driven to rotate, thereby driving the positioning block 331 and the connecting rod 33 which are directly engaged with the toothed disc 3 to move. The connecting rod 33 rotates in a circle with the toothed disc 3 as the center, driving the connecting rod 2 to slide in the slide groove 21, thereby moving the adjusting rod 23. Under normal conditions, when the adjusting rod 23 does not need to move, the electric push rod 332 contracts, causing the positioning block 331 to disengage from the toothed disc 3, and then contact and engage with the gear ring 32. Since the position of the gear ring 32 is fixed, after the positioning block 331 engages with the gear ring 32, the position of the connecting rod 33 can be fixed, thereby further fixing the position of the connecting rod 2.

[0054] Furthermore, in this embodiment, if Figure 7 and Figure 8As shown, one end of the connecting rod 33 away from the positioning block 331 is fixedly connected to a fixing block 34, a movable groove is provided on the surface of the fixing block 34, and a slider 341 is slidably connected to the movable groove, a clamping block 343 is fixedly connected to the top of the slider 341, and the length of the clamping block 343 is equivalent to the length of the connecting rod 2, the clamping block 343 is penetrated into the connecting rod 2, and an inclined block 345 and a clamping plate 344 are respectively provided in the connecting rod 2, the inclined block 345 is fixedly connected to the connecting rod 2, the clamping plate 344 is slidably connected to the inner wall of the connecting rod 2, and the clamping block 343 is located between the inclined block 345 and the clamping plate 344.

[0055] The opposite sides of the inclined block 345 and the clamping plate 344 are both configured as inclined surfaces, and the pressing block 343 is configured as a wedge shape.

[0056] Specifically, since the opposite sides of the inclined block 345 and the clamping plate 344 are both set as inclined surfaces, and the clamping block 343 is set as a wedge shape, when the clamping block 343 follows the movement of the fixed block 34 on the surface of the connecting rod 33, the wedge-shaped clamping block 343 will be pressed between the inclined block 345 and the clamping plate 344. Since the inclined block 345 is fixed in position, the continuous movement of the clamping block 343 will push the clamping plate 344 outward, causing the clamping plate 344 to move toward one side of the adjusting rod 23 and press against the position of the adjusting rod 23. At the same time, the clamping plate 344 can be synchronously pressed against the surface of the sliding sleeve 22 to fix the position of the sliding sleeve 22, and then position the sliding sleeve 22 and the adjusting rod 23. Accordingly, the side of the clamping plate 344 close to the adjusting rod 23 is set to a rough surface to increase friction, or a layer of rubber pad is set on the side of the clamping plate 344 close to the adjusting rod 23 to increase the clamping friction.

[0057] Among them, the moving direction of the clamping block 343 determines whether the clamping plate 344 will clamp the adjusting rod 23. Therefore, it can be set that when the connecting rod 33 moves in the direction away from the gear disc 3, the clamping block 343 presses the clamping plate 344, so that the clamping plate 344 clamps the adjusting rod 23, and when the connecting rod 33 moves in the direction close to the gear disc 3, that is, when the positioning block 331 engages with the gear disc 3, the clamping block 343 moves in the opposite direction, so that the clamping plate 344 no longer clamps the adjusting rod 23. At this time, the rotation of the gear disc 3 drives the connecting rod 2 and the adjusting rod 23 to move accordingly, and the position adjustment of the adjusting rod 23 is no longer hindered by the clamping plate 344.

[0058] The slider 341 is connected to the fixed block 34 through the tension spring 342. The two ends of the tension spring 342 are fixedly connected to the slider 341 and the fixed block 34 respectively. When the pressing block 343 moves transversely in the connecting rod 2, it is affected by the inclined surface of the inclined block 345, so that the slider 341 at the bottom of the pressing block 343 slides in the movable groove and stretches the tension spring 342. When the pressing block 343 moves transversely in the connecting rod 2 in the opposite direction, the slider 341 is gradually pulled back under the action of the rebound force of the tension spring 342, so that the pressing block 343 is always pressed against the inclined block 345, thereby improving the flexibility of clamping and releasing the clamping plate 344.

[0059] The surface of the sleeve 22 is provided with a screw hole 222. By providing the screw hole 222, a screw rod can be screwed into the screw hole 222, so that the screw rod is tightly pressed against the surface of the connecting rod 2, thereby helping to fix the sleeve 22 on the surface of the connecting rod 2 to improve the fastening strength.

[0060] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation mode. The above-mentioned specific implementation mode is merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make more forms of equivalent embodiments, all of which are within the protection of this embodiment.

Claims

1.

At this time, the patient stands without being acted upon by external forces. According to the patient's height and the position of the mold, the sliding sleeve (22) is operated to move longitudinally, and then the adjustment rod (23) is moved transversely so that the measuring plate (231) is closely attached to the measured position of the patient's body; S2: applying pressure at any position of the patient's spine through the pressure sensing block (232), simulating the pressure position and depth of the scoliosis brace to be produced later when taking the mold. At this time, the position of each measuring plate (231) is determined by the distance sensor (221), and the patient's body movement will not affect the misalignment and invalidation of the point position of the measuring plate (231); S3: stretching the patient. During the stretching process, the movement of the spine prompts the patient to adjust his posture to adapt to the state of the spine after stretching. The change in posture will lead to the redistribution of the center of gravity of the body weight, thereby affecting the pressure change of the feet on the force plate (13). The value of the pressure sensor in the force plate (13) changes to start the activity of the drive component. S4: The driving assembly drives the connecting rod (2) to move horizontally in the slide groove (21), thereby synchronously measuring the measured point position and surrounding pressure data during the patient's stretching process. The moving path of the measuring plate (231) can be guided by a flexibly curved universal tube (25), which is convenient for setting the moving path in advance. After the patient is fully stretched, the pressure depth of each part of the patient's spine is detected again; S5: Using the pressure sensing block (232), the spinal pressure depth detection data of the patient in a normal standing state without external force, during the stretching process, and after the stretching are respectively detected, and the data are integrated to form a final spinal orthotic sculpture model, and the orthosis is 3D printed for the patient to wear.
