Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a cervical traction device with multidimensional adjustment and real-time monitoring. Background Technology

[0002] Cervical traction is a routine physical intervention used in clinical practice to relieve the symptoms of cervical spondylosis. However, the cervical traction devices currently on the market still have shortcomings in terms of structure and control logic in practical applications.

[0003] Existing traction devices mostly use motors to directly wind or drive traction ropes for stretching. This purely rigid power transmission method lacks a physical buffer structure. During equipment startup, traction force increase or unloading, the power is directly applied to the human body, which can easily generate sudden tensile forces, causing rigid pulling on the patient's cervical spine and making it impossible to guarantee the smoothness and stability of the force application process.

[0004] Meanwhile, existing cervical traction devices usually have a fixed traction angle set manually before treatment begins. During traction, the device cannot acquire real-time information on changes in the patient's head position. When the patient's head position shifts due to fatigue or uneven local force, the device cannot dynamically adjust the traction height and angle according to the actual position, making it easy for the actual traction entry angle to deviate from the initially set standard range.

[0005] Furthermore, existing equipment lacks a robust stress relief and protection mechanism when dealing with abnormal conditions. Most devices rely solely on basic electronic programs for overload shutdown. When patients struggle violently or become severely misaligned during traction, or when the equipment experiences power outages or electronic sensor failures, the existing purely electronic protection measures cannot quickly and thoroughly release the traction tension. Due to the lack of passive mechanical limit physical protection structures, the equipment cannot automatically disconnect when subjected to excessive loads, making it highly susceptible to injury to patients due to continuous overload tension. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a cervical traction device with multi-dimensional adjustment and real-time monitoring, which solves the problems of traditional cervical traction devices being unable to dynamically adjust the traction force and traction angle according to the patient's real-time posture, and lacking an effective unloading and safety protection mechanism in abnormal states.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a cervical traction device with multi-dimensional adjustment and real-time monitoring, including a main support arm, which is used to support the overall device in the working position, a secondary support arm is installed at the upper end of the main support arm, which is used to adjust the traction angle of the overall device, a rotating frame is installed at the end of the secondary support arm away from the main support arm, a support component is provided at the lower end of the rotating frame, and a headgear is connected to the support component through a control component, the headgear being used to connect to the patient's head.

[0008] Preferably, the support assembly includes a support frame rotatably connected to the lower end of the rotating frame, a rotating wheel rotatably connected to the inner wall of the support frame, an A-frame fixedly connected to the lower surface of the support frame, a transmission rope sleeved on the outer wall of the rotating wheel, and the A-frame used to guide the movement of the transmission rope; a connecting block is fixedly connected to the end of the transmission rope away from the headgear, the connecting block slides on the inner wall of the A-frame, a slider is slidably connected to the inner wall of the A-frame near the lower part of the connecting block, and the slider and the connecting block are elastically connected by a pull rope spring; an adjusting screw is rotatably connected through the outer wall of the A-frame, the adjusting screw is threaded through and connected to the inner wall of the slider and its end abuts against the surface of the connecting block, and a tension adjusting motor is installed on the outer wall of the A-frame, the output shaft of the tension adjusting motor is fixedly connected to the adjusting screw, so as to control the initial tension length of the pull rope spring by controlling the initial distance between the slider and the connecting block, thereby controlling the magnitude of the tension output by the overall device.

[0009] Preferably, the main support arm includes a C-shaped frame with an electric telescopic rod mounted on its upper end, and a U-shaped frame is fixedly connected to the top of the output shaft of the electric telescopic rod; the secondary support arm includes a crossbar hinged to the inner wall of the U-shaped frame, a tilt adjustment motor is mounted on the upper surface of the crossbar, a transmission is mounted at the end of the crossbar, the output shaft of the tilt adjustment motor is connected to the input shaft of the transmission, and the output shaft of the transmission is fixedly connected to the rotating frame, so as to control the tilt angle of the rotating frame and the lower support assembly by activating the tilt adjustment motor.

[0010] Preferably, a sliding block is slidably connected through the upper surface of the U-shaped frame, a rotating shaft is inserted into the inner wall of the sliding block, and a pressing wheel is rotatably connected to the outer wall of the rotating shaft. A pressing block is slidably connected to the inner wall of the U-shaped frame near the lower surface of the sliding block, and a support screw is threaded through the inner wall of the pressing block. The support screw is rotatably connected to the outer wall of the U-shaped frame, and the contact surface between the pressing block and the sliding block is set to be inclined. The outer wall of the pressing wheel abuts against the lower surface of the crossbeam. By rotating the support screw, the pressing block is driven to move horizontally to press the sliding block and push it upward into an inclined position. When the downward pressure applied by the crossbeam exceeds the physical yield limit of the rotating shaft, the rotating shaft breaks, the pressing wheel separates from the sliding block, and the crossbeam moves downward to lose tension, thereby achieving passive mechanical limit protection.

[0011] Preferably, the control component includes a force measuring element, a position measuring element, and a control element installed on the outer wall of the C-shaped frame; the upper end of the force measuring element is connected to the transmission rope, and the lower end is connected to the headgear; multiple sets of position measuring elements are fixedly connected to the outer wall of the headgear, and the multiple sets of position measuring elements are symmetrically arranged with the center line of the headgear as the axis of symmetry; the control element integrates a microcontroller, a motor drive module, and a signal transceiver module, and the data output terminals of the force measuring element and the position measuring element are all collected and electrically connected to the signal input port of the control element.

[0012] Preferably, the force measuring element is a tension gauge, and the positioning element is a nine-axis attitude sensor with built-in accelerometer, gyroscope and magnetometer; the output terminal of the motor drive module of the control element is electrically connected to the electric telescopic rod, the tilt adjustment motor and the tension adjustment motor respectively.

[0013] Preferably, the microcontroller of the control element continuously receives tension and attitude signals. When the tension is detected to be lower than the preset lower limit, the tension adjustment motor is controlled to rotate forward to drive the slider to slide and forcibly stretch the pull rope spring to increase the traction force. When the tension is higher than the preset upper limit, the tension adjustment motor is reversed to cause the pull rope spring to contract for flexible unloading. When multiple sets of positioning elements detect that the pitch angle deviates from the standard range, the control element starts the tilt adjustment motor to drive the rotating frame and support assembly to rotate, and links the electric telescopic rod to extend and retract, driving the U-shaped frame and cross frame to rise and fall as a whole. Through the combined action of height and tilt angle, the headgear is adjusted to the standard pitch angle.

[0014] Preferably, the control element compares the data of the symmetrical positioning elements on both sides in real time. When there is a significant difference in the yaw angle or roll angle on both sides and it exceeds the preset symmetrical deviation threshold, the control element cuts off the operation of the tilt adjustment motor and the electric telescopic rod, and forces the tension adjustment motor to reverse at full speed so that the slider quickly abuts the connecting block to release the tension of the pull rope spring and achieve emergency safety unloading.

[0015] Preferably, the main support arm includes a C-shaped frame, with a compression screw threaded through and connected to the bottom of the C-shaped frame. A friction pad is fixedly connected to the upper end of the compression screw. By rotating the compression screw, the friction pad is moved upward, and the C-shaped frame is fixed to the outside of the hospital bed by the friction pad and the C-shaped frame approaching each other.

[0016] Preferably, a limiting ring is fixedly connected to the outer wall of the transmission rope, and a limiting frame is fixedly connected to the outer wall of the A-frame. The limiting frame is used to block the limiting ring to ensure that the initial position of the transmission rope and the headgear remains unchanged.

[0017] The present invention has the following beneficial technical effects: This device achieves automated closed-loop control of traction force and spatial posture through the cooperation of control elements, tension gauges, and attitude sensors. The device uses a tension adjustment motor to change the position of the slider and smooths the tension of the transmission rope on the headgear by adjusting the deformation of the rope spring, preventing rigid direct drag from impacting the human body. At the same time, based on the real-time detected head pitch angle data, the device dynamically corrects the height of the crossbeam and the angle of the rotating frame by linking the electric telescopic rod and the tilt adjustment motor, so that the traction cutting angle is always kept within the set reasonable range.

[0018] This device constructs a dual safety protection system that combines electronic and mechanical components. In terms of active protection, the system monitors the posture difference between the two sides of the headgear through symmetrically arranged posture sensors. Once it detects that the patient has abnormally tilted or struggled, causing the posture data difference to exceed the limit, the system cuts off the posture adjustment power and drives the tension adjustment motor to run in reverse, so that the slider and the connecting block abut against each other to release the spring tension and achieve rapid force relief. In terms of passive protection, a rotating shaft inserted into the inner wall of the sliding block is used as a mechanical limit component. When encountering power failure or control failure and the downward load exceeds the yield strength of the rotating shaft, the rotating shaft physically breaks, causing the crossbeam to lose support and fall, thereby completely relieving the traction force of the device and ensuring the safety of use in extreme situations.

[0019] This invention provides a cervical traction device with multi-dimensional adjustment and real-time monitoring, which has the following beneficial effects: 1. This invention achieves flexible tension output through the cooperation of a pull rope spring and a tension adjustment motor. The tension adjustment motor drives the adjustment screw to rotate, changing the position of the slider within the A-frame. The elastic deformation of the pull rope spring between the slider and the connecting block is used to smoothly adjust the traction force applied by the transmission rope to the headgear. This mechanical structure effectively avoids the rigid pulling caused by the motor directly driving the transmission rope, making the increase and unloading of traction force smooth and stable, and improving the safety of the force application process.

[0020] 2. This invention has a dynamic closed-loop adjustment function for spatial posture. Multiple sets of measuring elements installed on the outer wall of the headgear acquire posture data such as pitch angle in real time and feed it back to the control element. When the angle deviates from the set standard, the control element controls the electric telescopic rod to raise and lower as a whole, and simultaneously controls the tilt adjustment motor to drive the rotating frame to rotate. Through the physical combination of height and tilt angle, the device can automatically correct the patient's traction angle and keep it within the set reasonable range.

[0021] 3. This invention is equipped with a dual electromechanical limit protection mechanism. At the electronic control level, when the data difference between the two measuring elements exceeds the limit, the control element forces the tension adjustment motor to reverse to completely release the tension of the pull rope spring and achieve rapid unloading. At the mechanical and physical level, when an accident causes the downward pressure applied to the crossbeam to exceed the physical yield limit of the shaft, the shaft breaks directly, the compression wheel and the sliding block separate instantly, the crossbeam falls downward due to loss of support, and the transmission rope loses tension instantly, preventing injury to the user in extreme abnormal conditions.

[0024] The technical solutions in 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Example: Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a cervical traction device with multi-dimensional adjustment and real-time monitoring, including a main support arm 1 for supporting the overall device in the working position, a secondary support arm 2 for adjusting the traction angle of the overall device, a rotating frame 3 for the end of the secondary support arm 2 away from the main support arm 1, a support component 4 for the lower end of the rotating frame 3, and a headgear 5 for connecting the head of the patient via a control component 6.

[0026] The main support arm 1 includes a C-shaped frame 12. During installation, the C-shaped frame 12 can be fitted onto the outside of the hospital bed. A compression screw 110 is threaded through and connected to the bottom of the C-shaped frame 12. A friction pad 13 is fixedly connected to the upper end of the compression screw 110. By rotating the compression screw 110, the friction pad 13 can be moved upward and closer to the hospital bed. In this way, the C-shaped frame 12 is fixed to the outside of the hospital bed by the mutual proximity of the friction pad 13 and the C-shaped frame 12. An electric telescopic rod 11 is installed on the upper end of the C-shaped frame 12. A U-shaped frame 14 is fixedly connected to the top of the output shaft of the electric telescopic rod 11. The secondary support arm 2 includes a crossbar 21. The crossbar 21 is hinged to the inner wall of the U-shaped frame 14 to achieve horizontal support. A sliding block 17 is slidably connected through and connected to the upper surface of the U-shaped frame 14. A rotating shaft 18 is inserted into the inner wall of the sliding block 17. A compression wheel 19 is rotatably connected to the outer wall of the rotating shaft 18. The sliding block 17 can be mounted on the inner wall of the U-shaped frame 14. The compression wheel 19 slides downwards, its outer wall abutting against the lower surface of the crossbeam 21. The inner wall of the U-shaped frame 14 is slidably connected to the lower surface of the sliding block 17, with the compression block 16 slidably connected. The inner wall of the compression block 16 is threaded through and connected to the support screw 15, which is rotatably connected to the outer wall of the U-shaped frame 14. The contact surfaces between the compression block 16 and the sliding block 17 are inclined. By rotating the support screw 15, the compression block 16 can be moved horizontally on the inner wall of the U-shaped frame 14. The horizontal movement of the compression block 16 can compress the sliding block 17, causing it to move upwards. The sliding block 17 can lift the crossbeam 21 upwards, making it tilted. When the downward pressure applied to the crossbeam 21 is too great, the rotating shaft 18 will break. In this way, the compression wheel 19 will separate from the sliding block 17, and the crossbeam 21 will move downwards due to loss of support, thus causing the entire device to lose tension. This prevents excessive tension from injuring the user.

[0027] A tilt adjustment motor 22 is mounted on the upper surface of the crossbeam 21. A transmission device 23 is mounted on the left end of the crossbeam 21. The output shaft of the tilt adjustment motor 22 is connected to the input shaft of the transmission device 23. The output shaft of the transmission device 23 is fixedly connected to the rotating frame 3. By starting the tilt adjustment motor 22, the top of the rotating frame 3 can be rotated, thus changing the tilt angle of the rotating frame 3. This, in turn, controls the tilt angle of the support assembly 4 below the rotating frame 3, ultimately changing the angle at which the patient is pulled. The support assembly 4 includes a support frame 41, which is rotatably connected to the lower end of the rotating frame 3. The inner wall of the support frame 41 is rotatably connected to... The device includes a rotating wheel 42, a support frame 41 with an A-frame 43 fixedly connected to its lower surface, a transmission rope 44 sleeved on the outer wall of the rotating wheel 42, and a control component 6 including a force measuring element 61. The upper end of the force measuring element 61 is connected to the transmission rope 44, and the lower end of the force measuring element 61 is connected to the headgear 5. The force measuring element 61 can measure the tension applied to the patient. Multiple sets of position measuring elements 62 are fixedly connected to the outer wall of the headgear 5. The multiple sets of position measuring elements 62 are symmetrically arranged with the center line of the headgear 5 as the axis of symmetry, so that the position and posture of the headgear 5 can be measured. The A-frame 43 is used to guide the transmission rope 44 to move along a fixed trajectory.

[0028] The other end of the transmission rope 44 is fixedly connected to a connecting block 47. The connecting block 47 slides on the inner wall of the A-frame 43. A slider 48 is slidably connected to the inner wall of the A-frame 43 near the lower part of the connecting block 47. The slider 48 and the connecting block 47 are elastically connected by a pull rope spring 49. An adjusting screw 410 is rotatably connected through the outer wall of the A-frame 43. The adjusting screw 410 is threaded through and connected to the inner wall of the slider 48. At the same time, the end of the adjusting screw 410 abuts against the surface of the connecting block 47. This prevents the connecting block 47 and the slider 48 from getting too close and damaging the pull rope spring 49. A tension adjustment motor 411 is installed on the outer wall of the device 3. The output shaft of the tension adjustment motor 411 is fixedly connected to the adjustment screw 410. By controlling the rotation of the tension adjustment motor 411, the initial distance between the slider 48 and the connecting block 47 can be controlled. This will notify the initial tension length of the pull rope spring 49, thereby controlling the magnitude of the tension output by the overall device. A limit ring 46 is fixedly connected to the outer wall of the transmission rope 44, and a limit frame 45 is fixedly connected to the outer wall of the A-frame 43. The limit frame 45 is used to block the limit ring 46, thus preventing the transmission rope 44 from changing its initial position relative to the headgear 5.

[0029] The outer wall of the C-shaped frame 12 is equipped with a control element 63. To achieve automated monitoring and adjustment of this device, the control element 63 integrates a microcontroller, a motor drive module, and a signal transceiver module. Clear electrical and signal connections are established between the various electrical components. The force measuring element 61 is specifically a tension gauge, and the position measuring element 62 is specifically a nine-axis attitude sensor with built-in accelerometer, gyroscope, and magnetometer. The multiple sets of nine-axis attitude sensors on the headgear 5 and the tension gauge at the end of the transmission rope 44 are all connected to flexible data lines at their data output ends. The flexible data lines run along the inner cable trays of the transmission rope 44, support frame 41, rotating frame 3, auxiliary support arm 2, and main support arm 1, and finally converge and are electrically connected to the signal input port of the control element 63. This is used to continuously transmit the analog or digital signal of the tension magnitude and the attitude signals such as the pitch angle, yaw angle, and roll angle of the headgear to the microcontroller in real time.

[0030] The output of the motor drive module of the control element 63 is electrically connected to the electric telescopic rod 11 on the main support arm 1, the tilt adjustment motor 22 on the crossbeam 21, and the tension adjustment motor 411 on the A-frame 43 via power control lines. Through this hardware arrangement, the control element 63 can independently transmit control commands and provide drive power to each actuator, ensuring that each motor and telescopic element can make a precise mechanical response according to the system commands, thereby providing a solid physical foundation for the automatic closed-loop regulation of the entire device.

[0031] In terms of basic control logic, the storage module inside the control element 63 is pre-written with threshold ranges for the lower and upper limits of the tension suitable for the patient, as well as the standard posture angle range and symmetry deviation threshold of the nine-axis posture sensor. During traction therapy, the microcontroller of the control element 63 continuously receives real-time electrical signals from the tension gauge and the nine-axis posture sensor, and continuously performs logical comparisons with the pre-stored threshold ranges. Based on the comparison results, the microcontroller outputs voltage signals with different duty cycles or polarities to independently control the lifting and lowering of the electric telescopic rod 11, the start and stop and forward and reverse rotation of the tilt adjustment motor 22, and the start and stop and forward and reverse rotation of the tension adjustment motor 411, thereby adjusting and stabilizing the tension and posture parameters in real time within the preset safe and effective range.

[0032] Working principle: In actual operation, the cervical traction device provided in this embodiment of the invention first requires the C-shaped frame 12 at the bottom of the main support arm 1 to be fitted onto the outside of the hospital bed. The operator rotates the compression screw 110 to move the friction pad 13 upward toward the bottom of the hospital bed. The friction pad 13 and the top surface of the C-shaped frame 12 clamp each other to firmly fix the entire device to the outside of the hospital bed. Then, the operator rotates the support screw 15 to move the compression block 16 horizontally and compress the sliding block 17 to slide upward. The sliding block 17 lifts the cross frame 21 upward to the required angle through the rotating shaft 18 and the compression wheel 19. Finally, the headgear 5 is put on the patient's head. At this time, the limiting frame 45 blocks the limiting ring 46 on the transmission rope 44 to ensure that the initial position and tension benchmark of the transmission rope 44 and the headgear 5 remain unchanged, thus completing the initial fixation and wearing of the device.

[0033] After traction therapy is initiated, the system enters a phase of automatic closed-loop adjustment of tension based on flexible buffering and dynamic tracking adjustment of spatial posture. The tension gauge detects the tension of the transmission rope 44 on the headgear 5 in real time. When the control element 63 detects that the tension is lower than the preset lower limit, it controls the tension adjustment motor 411 to rotate forward, driving the adjustment screw 410 to rotate, causing the slider 48 to slide away from the connecting block 47 within the A-frame 43, forcibly stretching the rope spring 49. Its elasticity smoothly increases the traction tension through the connecting block 47 until the value reaches the target. When the tension exceeds the preset upper limit... When the value is reached, the tension adjustment motor 411 reverses to retract the rope spring 49, and the traction force is then flexibly unloaded. At the same time, if multiple sets of nine-axis attitude sensors detect that the patient's head is excessively tilted forward or backward, causing the pitch angle to deviate from the standard range, the control element 63 will start the tilt adjustment motor 22, which drives the rotating frame 3 and support assembly 4 to rotate through the transmission 23 to change the traction entry angle, and links the electric telescopic rod 11 to extend and retract, driving the U-shaped frame 14 and the cross frame 21 to rise and fall as a whole. Through the combined action of height and tilt angle, the headgear 5 is precisely adjusted to the standard pitch angle.

[0034] During traction, the device also features a dual electromechanical safety protection mechanism to cope with extreme abnormal situations. One aspect is active electronic anomaly protection. The control element 63 compares the data from the symmetrical nine-axis attitude sensors on both sides of the headgear 5 in real time. When a significant difference occurs in the yaw angle or roll angle on both sides and exceeds the preset symmetry deviation threshold, it determines that the patient is experiencing dangerous neck twisting or torsional struggle. At this time, the control element 63 immediately cuts off the operation of the tilt adjustment motor 22 and the electric telescopic rod 11, and forces the tension adjustment motor 411 to reverse at full speed, causing the slider 48 to quickly abut against the connecting block 47. The tension of the bottom release rope spring 49 is used to achieve emergency safety relief. On the other hand, it is a passive mechanical limit protection. In the event of an accidental power outage or electronic system failure, if the patient is subjected to excessive downward pulling force, the limit pressure will be transmitted to the crossbar 21. When the downward pressure exceeds the physical yield limit of the rotating shaft 18, the rotating shaft 18 will break. The squeezing wheel 19 will separate from the sliding block 17 instantly. The crossbar 21 will fall rapidly downward due to the loss of support below, causing the transmission rope 44 and the headgear 5 to instantly lose all tension, thereby preventing excessive tension from causing irreversible damage to the patient's cervical spine.

A cervical traction device with multi-dimensional adjustment and real-time monitoring according to claim 3, characterized in that: The control component (6) includes a force measuring element (61), a position measuring element (62), and a control element (63) installed on the outer wall of the C-shaped frame (12). The upper end of the force measuring element (61) is connected to the transmission rope (44), and the lower end is connected to the headgear (5); a number of the measuring elements (62) are fixedly connected to the outer wall of the headgear (5), and the multiple sets of measuring elements (62) are symmetrically arranged with the center line of the headgear (5) as the axis of symmetry. The control element (63) integrates a microcontroller, a motor drive module and a signal transceiver module. The data output terminals of the force measuring element (61) and the position measuring element (62) are all connected to the signal input port of the control element (63).

6. A cervical traction device with multi-dimensional adjustment and real-time monitoring according to claim 5, characterized in that: The force measuring element (61) is a tension gauge, and the position measuring element (62) is a nine-axis attitude sensor with built-in accelerometer, gyroscope and magnetometer; The output terminal of the motor drive module of the control element (63) is electrically connected to the electric telescopic rod (11), the tilt adjustment motor (22), and the tension adjustment motor (411), respectively.

7. A cervical traction device with multi-dimensional adjustment and real-time monitoring according to claim 6, characterized in that: The microcontroller of the control element (63) continuously receives tension signals and attitude signals. When it detects that the tension is lower than the preset lower limit, it controls the tension adjustment motor (411) to rotate forward to drive the slider (48) to slide and forcibly stretch the rope spring (49) to increase the traction force. When the tension is higher than the preset upper limit, the tension adjustment motor (411) reverses to cause the rope spring (49) to contract for flexible unloading. When multiple sets of the positioning elements (62) detect that the pitch angle deviates from the standard range, the control element (63) starts the tilt adjustment motor (22) to drive the rotating frame (3) and the support assembly (4) to rotate, and links the electric telescopic rod (11) to extend and retract, driving the U-shaped frame (14) and the cross frame (21) to rise and fall as a whole. Through the combined action of height and tilt angle, the headgear (5) is adjusted to the standard pitch angle.

8. A cervical traction device with multi-dimensional adjustment and real-time monitoring according to claim 6, characterized in that: The control element (63) compares the data of the symmetrical measuring elements (62) on both sides in real time. When there is a significant difference in the yaw angle or roll angle on both sides and it exceeds the preset symmetry deviation threshold, the control element (63) cuts off the operation of the tilt adjustment motor (22) and the electric telescopic rod (11), and forces the tension adjustment motor (411) to reverse at full speed so that the slider (48) quickly abuts against the connecting block (47) to release the tension of the pull rope spring (49) and achieve emergency safety unloading.
