Description

Technical Field

[0001] This invention relates to the field of lumbar traction device technology, and in particular to a lumbar traction device for treating bone injuries in traditional Chinese medicine. Background Technology

[0002] Lumbar spine diseases such as lumbar disc herniation and lumbar spinal stenosis fall under the categories of Bi syndrome and low back pain in traditional Chinese medicine. Their pathogenesis is mostly due to falls, strain, or invasion of wind, cold, and dampness, leading to malnourishment of the Du meridian, stagnation of Qi and blood, and compression of the flow of Qi and blood in the meridians. Lumbar traction, as a core method of conservative treatment, can effectively relieve intervertebral disc pressure and correct facet joint disorders by mechanically stretching the intervertebral space. It has significant efficacy in the treatment of lumbar disc herniation, lumbar spinal stenosis, and other diseases.

[0003] A search revealed a Chinese patent for a lumbar traction device for treating bone injuries in traditional Chinese medicine, publication number CN120694793A. The device includes a lumbar traction assembly with a bracket fixedly connected to its bottom surface. The lumbar traction assembly includes a fixing plate and a traction plate. A traction part is provided on the bottom surface of the fixing plate, and the traction part is used to move the traction plate to provide static traction to the patient's lumbar spine.

[0004] The aforementioned lumbar traction device retains the function of static traction while also having the function of dynamic traction. It can perform periodic reciprocating traction, thereby rhythmically stretching and improving muscle microcirculation, which can effectively improve lumbar muscle strain. Furthermore, it can automatically provide auxiliary heat therapy to the patient's lumbar spine while performing traction, thereby further improving the treatment effect.

[0005] However, the aforementioned lumbar traction devices employ a traction countermeasure structure with an axillary limiting rod and a foot limiting frame, which violates the biomechanical principles of lumbar traction. Clinically standardized lumbar traction requires rigid countermeasure from the thoracic cage to the pelvis to precisely apply traction force to the lumbar segments. Axillary limiting concentrates the traction force in the axilla, which can easily compress the axillary artery and brachial plexus, leading to limb numbness, ischemia, or even permanent nerve damage, making it difficult to meet clinical treatment requirements. Furthermore, the static traction of this type of traction device relies solely on a servo motor for position control, without traction force detection or closed-loop force adjustment. Under the same traction stroke, the traction force varies greatly among different patients, easily leading to the risk of insufficient or excessive traction. Moreover, since the traction ends are fixed at the head and foot of the bed, once the flexion, lateral flexion, or rotation position is adjusted, the direction of traction force will deviate from the physiological axis of the lumbar spine, reducing the intervertebral space opening efficiency and potentially causing soft tissue traction injury.

[0006] Therefore, in response to the problems of poor biomechanical adaptability, high risk, insufficient traction force control precision, and easy deviation of force line in existing lumbar traction devices, a lumbar traction device for the treatment of bone injuries in traditional Chinese medicine was developed. Summary of the Invention

[0007] The purpose of this invention is to provide a lumbar traction device for treating bone injuries in traditional Chinese medicine, in order to solve the problems mentioned in the background art above: To achieve the above objectives, the present invention provides the following technical solution: A lumbar traction device for treating bone injuries in traditional Chinese medicine includes a bed frame main beam. The upper part of the bed frame main beam has a pelvic lower limb segment fixation bed board and a head and chest segment fixation bed board respectively installed on the front and rear ends via a support crossbeam. Slide rails are fixedly installed on both sides of the bed frame main beam, and a traction component is provided on the upper part of the bed frame main beam. The traction assembly includes a thoracic lateral traction unit and a pelvic lateral traction unit. The thoracic lateral traction unit includes thoracic lateral traction sliders that slide with two slide rails. An adjustable support plate is movably mounted on the side of the two thoracic lateral traction sliders away from the main beam of the bed frame via an L-shaped mounting plate. A ball socket is fixedly mounted on the top of the adjustable support plate. A universal ball joint is nested inside the ball socket. The universal ball joint is connected to a telescopic rod via a swing rod. A connecting rod is installed at the end of the telescopic rod, and the end of the connecting rod is connected to a thoracic fixation member. The pelvic lateral traction unit includes pelvic lateral traction sliders that slide with two slide rails. A ball socket is also mounted on the outer side of the two pelvic lateral traction sliders via an L-shaped mounting plate and an adjustable support plate. A universal ball joint is also nested inside the ball socket. A pelvic fixation member is also installed on the universal ball joint via a swing rod, a telescopic rod, and a connecting rod. A tension sensor is installed on one lower side of the thoracic traction slider, and a traction pulley is installed on the outer lower side of the pelvic traction slider. Follower fixed pulleys are slidably installed on the outer side of the two slide rails and in front of the pelvic traction sliders. Guide fixed pulleys are also installed at the rear end of the slide rails through the traction slider and the L-shaped mounting plate. The U-shaped rope grooves of the traction pulley, guide fixed pulley and follower fixed pulley are in the same longitudinal plane.

[0008] Preferably, the traction slider on the thoracic side and the traction slider for fixing the tension sensor are provided with an unlockable locking mechanism at one rear position. The adjustable support plate and the L-shaped mounting plate are hinged by a hinge shaft, and the end of the hinge shaft is provided with an angle locking nut for locking the support angle of the adjustable support plate.

[0009] By adopting the above technical solution, before traction treatment, personnel can loosen the angle locking nut to adjust the angle of the adjustable support plate, thereby adjusting the angle of the universal ball joint to adapt to the different thoracic physiological structures of patients, eliminate the additional stress caused by changes in body position, and improve fixation adaptability and stability.

[0010] Preferably, a drive assembly is provided on both sides of the main beam of the bed frame at a rearward position. The drive assembly includes a drive motor, a drive screw, and a pull slider. The drive screw is installed on both sides of the main beam of the bed frame at an upper position via a support frame. The output shaft of the drive motor is connected to one end of the drive screw via a coupling. The pull slider is slidably installed on the side of the main beam of the bed frame, and the pull slider is threadedly engaged with the drive screw.

[0011] By adopting the above technical solution, during traction therapy, the traction stroke and traction force can be precisely controlled through the drive screw and drive motor transmission, ensuring the accuracy and stability of the traction action and adapting to the needs of both static and dynamic traction modes.

[0012] Preferably, a traction rope fixing head is provided at the center of the side of the pull slider away from the main beam of the bed frame, and a support sleeve is provided at the front and rear ends of the outer ring of the drive screw. The outer ring of the support sleeve is equipped with a travel limit switch through an adjusting sleeve.

[0013] By adopting the above technical solution, when the traction rope is moving, the traction force can be coaxially transmitted through the traction rope fixing head, avoiding the block jamming caused by radial force. In addition, the travel limit switch can limit the movement limit of the pulling block and avoid the safety risk of excessive traction due to overtravel.

[0014] Preferably, the connecting rod and the telescopic rod are slidably connected, and the connecting rod has an internal telescopic groove. A length locking screw is threaded through the top of the connecting rod, and several equidistant adjustment holes are opened at the upper and lower ends of the telescopic rod. The telescopic rod is used to adapt to the installation position and length of the pelvic fixation component by telescopic movement.

[0015] By adopting the above technical solution, the overall length of the guide rod can be flexibly adjusted by extending and retracting the telescopic rod inside the connecting rod when treating different patients, so as to adapt to the distance between the thorax and pelvis of patients with different heights and body types. Furthermore, by screwing the length locking screw into the corresponding adjustment hole, the length shift during traction can be avoided.

[0016] Preferably, the locking mechanism of the tension sensor and the traction slider on the thoracic side is a set screw bolt locking mechanism, which is used to rigidly lock the tension sensor and the traction slider on the thoracic side to the slide rail after adjustment.

[0017] By adopting the above technical solution, the thorax traction slider and the tension sensor can be aligned and fixed when they reach the corresponding positions to avoid slippage. Moreover, the top screw locking mechanism can be locked and unlocked by hand without the need for auxiliary tools, which makes it highly flexible in use.

[0018] Preferably, each of the bottom corners of the main beam of the bed frame is equipped with an electric lifting column, which can be used to adjust the overall height of the main beam of the bed frame to accommodate the needs of doctors for manual intervention and traction combined treatment under multiple body position operations.

[0019] By adopting the above technical solution, the overall height of the main beam of the bed frame can be adjusted through the electric lifting column during traction. When the main beam of the bed frame is in a low position of about 50cm, it is suitable for doctors to perform fine spinal adjustments while sitting. When it is in a middle position of about 70cm, it is suitable for doctors to perform lumbar massage and foot massage while standing. When it is in a high position of about 90cm, it is convenient for doctors to use gravity to perform traction and shaking techniques.

[0020] Preferably, the lower parts of the thoracic fixation member and the pelvic fixation member are both rigid plates, and the connection between the rigid plate and the connecting rod is provided with a fisheye joint.

[0021] By adopting the above technical solutions, the rigid plate setting can ensure that the traction force is evenly transmitted to the patient's chest and pelvis during traction therapy, avoiding discomfort caused by local stress concentration. The fisheye joint can adapt to the angular deviation between the fixing part and the connecting rod, further adapting to changes in the patient's body position and eliminating additional torsional force.

[0022] Preferably, a foldable lumbar support plate is movably installed on the inner front position of the main beam of the bed frame via a damping hinge. The foldable lumbar support plate is folded downward to expose the operating space on both sides and behind the patient's lower back.

[0023] By adopting the above technical solution, after the foldable support plate in the lumbar spine is fully folded, the operating space on both sides and the back of the patient can be fully exposed. Doctors can perform osteopathic massage techniques while maintaining traction without interrupting traction, thus improving the continuity of treatment.

[0024] Preferably, the top surfaces of the pelvic lower limb fixation bed board, the head and chest fixation bed board, and the damping hinges, as well as the inner sides of the pelvic fixation component and the thoracic fixation component, are all provided with medical pads, and the lower parts of the thoracic fixation component and the pelvic fixation component are all provided with ventilation holes.

[0025] By adopting the above technical solutions, medical cushions can improve the comfort of patients during treatment, avoid pressure sores caused by rigid structures compressing the skin, and prevent stuffiness and discomfort caused by prolonged binding through ventilation holes, thus meeting the humanized design requirements of clinical medical equipment.

[0026] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a traction component, traction pulley, follower fixed pulley, and guide fixed pulley, allows the traction fixation part to completely avoid the axillary region during lumbar traction treatment, eliminating the risk of iatrogenic injury from axillary artery and brachial plexus compression at the source, ensuring that the traction force acts on the lumbar segment. Furthermore, the ball-and-socket seat and universal ball joint can be used to adapt to patient position adjustments. Simultaneously, the traction rope's direction can be adjusted via a slide rail and three follower fixed pulleys, traction pulleys, and guide fixed pulleys located in the same longitudinal plane, ensuring that the traction force is always coaxially loaded along the physiological force line of the lumbar spine, avoiding traction injury caused by force line deviation due to positional changes, improving the efficiency of intervertebral space opening, and conforming to clinical lumbar traction treatment standards.

[0027] 2. This invention, by setting up a drive component, a tension sensor, and a travel limit switch, can achieve static continuous traction and dynamic reciprocating traction during the traction process. At the same time, by relying on the drive motor and the traction rope fixing head to control the tension of the traction rope, it can ensure that the tension is stably maintained within a suitable range to meet the treatment requirements of intervertebral disc opening. Furthermore, the tension sensor can detect the net traction force in real time, which makes it easy to adjust the traction force according to the patient's condition and avoid the risk of insufficient or excessive traction.

[0028] 3. This invention, through the combination of a pelvic lower limb segment fixation bed board, a head and chest segment fixation bed board, damping hinges, and an electrically adjustable lifting column, allows the lumbar spine segment foldable support plate to be folded downwards during traction therapy, exposing the patient's lumbar and back operating space. Doctors can simultaneously perform traditional Chinese medicine techniques such as bone setting, massage, and repositioning while maintaining traction and continuous intervertebral space opening. The height of the bed can be adjusted in real time via the electrically adjustable lifting column to suit the doctor's sitting or standing operating needs. Attached Figure Description

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figure 1 - Figure 8 As shown, a lumbar traction device for treating bone injuries in traditional Chinese medicine includes a bed frame main beam 1. The upper part of the bed frame main beam 1 is supported by a crossbeam 2 and a pelvic lower limb segment fixing bed board 301 and a head and chest segment fixing bed board 302 are respectively installed at the front and rear ends. Slide rails 5 are fixedly installed on both sides of the bed frame main beam 1, and a traction component 6 is provided on the upper part of the bed frame main beam 1. Traction assembly 6 includes a thoracic lateral traction unit and a pelvic lateral traction unit. The thoracic lateral traction unit includes thoracic lateral traction sliders 601 that slide with two slide rails 5. An adjustable support plate 604 is movably mounted on the side of the two thoracic lateral traction sliders 601 away from the main beam 1 of the bed frame via an L-shaped mounting plate 602. A ball joint seat 605 is fixedly mounted on the top of the adjustable support plate 604. A universal ball joint 606 is nested inside the ball joint seat 605. The universal ball joint 606 is connected to a telescopic rod 608 via a swing rod 607. The telescopic rod 608... The end of the unit is equipped with a connecting rod 609, and the end of the connecting rod 609 is connected to a thoracic fixation member 6012. The pelvic traction unit includes a pelvic traction slider 601 that slides with two slide rails 5. The outer sides of the two pelvic traction sliders 601 are also equipped with ball socket seats 605 through L-shaped mounting plates 602 and adjustable support plates 604. A universal ball joint 606 is also nested inside the ball socket seat 605. The universal ball joint 606 is also equipped with a pelvic fixation member 6011 through a swing rod 607, a telescopic rod 608 and a connecting rod 609. A tension sensor 704 is installed on one side of the lower part of the thoracic traction slider 601, and a traction pulley 701 is installed on the outer side of the lower part of the pelvic traction slider 601. A follower fixed pulley 702 is slidably installed on the outer side of the two slide rails 5 and in front of the pelvic traction slider 601. A guide fixed pulley 703 is also installed at the rear end of the slide rail 5 through the traction slider 601 and the L-shaped mounting plate 602. The U-shaped rope grooves of the traction pulley 701, the guide fixed pulley 703 and the follower fixed pulley 702 are in the same longitudinal plane.

[0033] As a technical optimization of the present invention, the traction slider 601 on the thoracic side and the traction slider 601 used to fix the tension sensor 704 are provided with an unlockable locking mechanism at one rear position. The adjustable support plate 604 and the L-shaped mounting plate 602 are hinged by a hinge shaft, and the end of the hinge shaft is provided with an angle locking nut 603 for locking the support angle of the adjustable support plate 604.

[0034] By loosening the angle locking nut 603, the angle of the adjustable support plate 604 can be adjusted, thereby adjusting the angle of the universal ball joint 606 to adapt to the different thoracic physiological structures of patients, eliminate the additional stress caused by changes in body position, and improve fixation adaptability and stability.

[0035] As a technical optimization of the present invention, drive components 8 are provided on both sides of the main beam 1 at the rear position. The drive components 8 include a drive motor 802, a drive screw 801, and a pull slider 803. The drive screw 801 is installed on both sides of the main beam 1 at the upper position through a support frame. The output shaft of the drive motor 802 is connected to one end of the drive screw 801 through a coupling. The pull slider 803 is slidably installed on the side of the main beam 1, and the pull slider 803 is threadedly engaged with the drive screw 801.

[0036] By using the drive screw 801 in conjunction with the drive motor 802, precise control of traction stroke and traction force can be achieved, ensuring the accuracy and stability of traction action and adapting to both static and dynamic traction requirements.

[0037] As a technical optimization of the present invention, a traction rope fixing head 804 is provided in the center of the side of the pull slider 803 away from the main beam 1 of the bed frame, and a support sleeve is provided at the front and rear ends of the outer ring of the drive screw 801. The outer ring of the support sleeve is equipped with a travel limit switch 806 through the adjusting sleeve 805.

[0038] The traction rope fixing head 804 ensures that the traction force is transmitted coaxially, avoiding the block jamming caused by radial force. The travel limit switch 806 can limit the movement limit of the sliding block 803, avoiding the safety risk of overtravel and excessive traction.

[0039] As a technical optimization of the present invention, the connecting rod 609 and the telescopic rod 608 are slidably connected, and the connecting rod 609 is provided with a telescopic groove inside. A length locking screw is threaded through the top end of the connecting rod 609. Several equidistant adjustment holes are provided through the upper and lower ends of the telescopic rod 608. The telescopic rod 608 is used to adapt to the installation position and length of the pelvic fixation component 6011 by telescopic extension and retraction.

[0040] The overall length of the guide rod can be flexibly adjusted by telescopic rod 608 extending and retracting inside connecting rod 609, adapting to the distance between the chest and pelvis of patients of different heights and body types. Furthermore, by screwing the length locking screw into the corresponding adjustment hole, the length shift during traction can be avoided.

[0041] As a technical optimization of the present invention, the locking mechanism of the tension sensor 704 and the traction slider 601 on the thoracic side is a set screw locking mechanism, which is used to rigidly lock the tension sensor 704 and the traction slider 601 on the thoracic side to the slide rail 5 after adjustment.

[0042] When the thorax lateral traction slider 601 and the tension sensor 704 reach the corresponding positions, they can be aligned and fixed to prevent slippage. The set screw locking mechanism allows for locking and unlocking by hand without the need for auxiliary tools, providing high flexibility in use.

[0043] As a technical optimization of the present invention, electric lifting columns 4 are installed at the bottom corners of the main beam 1 of the bed frame. The overall height of the main beam 1 of the bed frame is adjusted by raising and lowering the electric lifting columns 4 to adapt to the needs of manual intervention and traction combined treatment under the multi-position operation of physicians.

[0044] During traction, the overall height of the main beam 1 of the bed frame can be adjusted at four points via electric lifting columns. When the main beam 1 of the bed frame is in a low position of about 50cm, it is suitable for doctors to perform fine spinal adjustments while sitting. When it is in a middle position of about 70cm, it is suitable for doctors to perform lumbar compression and foot massage while standing. When it is in a high position of about 90cm, it is convenient for doctors to use gravity to perform traction and shaking techniques.

[0045] As a technical optimization of the present invention, the lower parts of the thoracic fixation member 6012 and the pelvic fixation member 6011 are both rigid plates, and a fisheye connector 6010 is provided at the connection between the rigid plate and the connecting rod 609.

[0046] The rigid plate design ensures that the traction force is evenly transmitted to the patient's chest and pelvis, avoiding discomfort caused by local stress concentration. The fisheye connector 6010 can accommodate the angular deviation between the fixing component and the connecting rod 609, further adapting to changes in the patient's position and eliminating additional torsional force.

[0047] As a technical optimization of the present invention, a lumbar vertebral segment foldable support plate 304 is movably installed on the inner front position of the main beam 1 of the bed frame via a damping hinge 303. The lumbar vertebral segment foldable support plate 304 is folded downward to expose the operating space on both sides and the back of the patient's waist and back.

[0048] After the 304 foldable support plate in the lumbar spine is fully folded, the operating space on both sides and the back of the patient can be fully exposed. Doctors can perform osteopathic massage techniques while maintaining traction without interrupting traction, thus improving the continuity of treatment.

[0049] As a technical optimization of the present invention, medical pads are provided on the top surfaces of the pelvic lower limb fixation bed board 301, the head and chest fixation bed board 302, the damping hinge 303, and the inner sides of the pelvic fixation member 6011 and the thoracic fixation member 6012, and ventilation holes are provided at the lower parts of the thoracic fixation member 6012 and the pelvic fixation member 6011.

[0050] Medical cushions can improve patient comfort during lying down and traction fixation, avoid pressure sores caused by rigid structures compressing the skin, and prevent stuffiness and discomfort caused by prolonged binding through ventilation holes, meeting the humanized design requirements of clinical medical equipment.

[0051] It should be noted that this invention is a lumbar traction device for the treatment of bone injuries in traditional Chinese medicine. In the prior art, the steps of fixing the patient's chest and pelvis through the thoracic fixation component 6012 and the pelvic fixation component 6011 will not be repeated here. When fixing the pelvis, it is necessary to ensure that the force application point of the traction rope is located slightly below the anterior superior iliac spine, which is the position where the pelvis can withstand the most tension. The thoracic fixation component 6012 needs to be tied to the lower part of the patient's sternum to the lower edge of the bilateral costal arches to avoid the risk of compression of the axillary artery and brachial plexus. During the preparation phase, personnel can start the drive motor 802 of the drive assembly 8, which drives the drive screw 801 to rotate synchronously. At this time, the slider 803 is pulled to return to the origin along the screw axis. After triggering the travel limit switch 806 on the origin side, the machine stops automatically, ensuring that the traction drive end is in the initial zero position. At the same time, before fixing, personnel can push the traction slider 601 corresponding to the pelvic fixation component 6011 and the thoracic fixation component 6012 to the initial reference position along the slide rail 5, and slide the matching slider of the follower fixed pulley 702 to the initial position in the middle section of the slide rail 5. Subsequently, the first end of the external traction rope can be rigidly anchored to the force measuring point of the tension sensor 704, and the end of the traction rope away from the tension sensor 704 can be extended longitudinally along the slide rail 5 towards the foot of the bed, passing around the traction pulley 701 at the traction slider 601 on the pelvic fixation component 6011 to complete the first reversal. Then, it can be extended towards the head of the bed again, passing around the freely sliding follower fixed pulley 702 on the slide rail 5 to complete the second reversal. After the traction rope is reversed, it passes around the guide fixed pulley 703 at the end of the bed foot drive assembly 8, and then the end of the traction rope is fixed to the pull slider 803 through the traction rope fixing head 804 to complete the layout of the entire traction transmission link. It is necessary to ensure that the traction rope is taut throughout the entire process without slack or knotting. At this point, the patient's torso is aligned with the longitudinal centerline of the bed, with the head and upper chest positioned in the corresponding area of ​​the head-chest fixed bed board 302, the lower back in the corresponding area of ​​the lumbar vertebral foldable support board 304, and the pelvis and lower limbs in the corresponding area of ​​the pelvic lower limb fixed bed board 301. After ensuring safety, the operator can control the drive motor 802 to start at low speed in the forward direction, driving the drive screw 801 to rotate at low speed, which in turn drives the pull slider 803 to move slowly along the screw towards the end of the bed, gradually tensioning the traction rope. When the traction force reaches the set target value, the drive motor 802 automatically locks. With the real-time feedback from the tension sensor 704, the rotation angle of the drive screw 801 and the position of the pull slider 803 are dynamically and finely adjusted to compensate for the tension fluctuations caused by the extension of the traction rope and changes in body position, ensuring that the traction force is stably maintained within the set treatment range, achieving continuous and stable opening of the lumbar intervertebral space, and meeting the treatment needs of conventional lumbar traction. Simultaneously, the drive motor 802 drives the drive screw 801 to rotate periodically in both directions, which in turn drives the pull slider 803 to perform reciprocating linear motion. Through the transmission of the traction rope and pulley group, the pelvic side traction slider 601 is driven to move periodically along the slide rail 5, thereby realizing rhythmic reciprocating traction on the patient's lumbar spine. The rhythmic stretching improves the microcirculation of the lumbar muscles, relieves lumbar muscle strain, and conforms to the treatment concept of traditional Chinese medicine that emphasizes both bone and tendon injuries. During traction, if the patient adjusts their flexion, lateral flexion, and rotation position independently, the universal ball joint 606 automatically adapts to the full degree of freedom as the trunk swings, and the follow-up fixed pulley 702 automatically slides along the slide rail 5 to adjust the direction of the traction rope, always keeping the traction force coaxially loaded along the physiological force line of the lumbar spine, avoiding soft tissue traction injury caused by force line deviation. When the patient is in a flexed position, the thoracic fixation member 6012 moves forward as a whole with the forward tilt of the thoracic cavity, while the connection between the back plate and the connecting rod 609 rotates forward. At this time, the universal ball joint 606 provides a degree of pitch freedom, allowing the connecting rod 609 to rotate forward relative to the adjustable support plate 604. The adjustable support plate 604 remains stably locked on the L-shaped mounting plate 602, but the thoracic fixation member 6012 can adapt to the patient's bending posture through the rotation of the ball joint, avoiding the upper edge of the strap compressing the sternum or the lower edge of the strap lifting up due to the forward tilt of the body. When the patient flexes laterally, their trunk bends to the left, compressing the left costal arch and stretching the right costal arch, resulting in a tilting tendency that is lower on the left and higher on the right. At this time, the universal ball joint 606 on one side will deflect, allowing the left connecting ear to adjust the angle upward relative to the adjustable support plate 604 to adapt to the space on the compressed side, while the adjustable support plate 604 on the right side will deflect in the opposite direction, allowing the connecting ear to adjust downward to avoid generating huge shearing forces on the right side of the patient's abdomen. When the patient's torso rotates, the left costal arch moves backward and the right costal arch moves forward. The thoracic fixation piece 6012 twists in the horizontal plane. At this time, the universal ball joints 606 on the left and right sides will each undergo a combination of rolling and deflection. That is, the left ball joint allows the connecting ear to swing backward and the right ball joint allows the connecting ear to swing forward. This can dissipate the torque generated by the torso rotation at the hinge, avoid the torque being transmitted to the slider and guide rail, and prevent the torso from being forcibly twisted. When it is necessary to perform traditional Chinese medicine bone setting, massage, and lumbar spine reduction techniques under traction maintenance, medical staff can directly fold the lumbar spine foldable support plate 304 downwards. During the folding process, the damping hinge 303 provides stable damping to prevent the support plate from falling rapidly and causing impact. After the support plate is fully folded, the operating space on both sides and the back of the patient's lower back is fully exposed. Doctors can directly perform bone setting, massage, reduction and other techniques on the lumbar spine segments under continuous traction without interrupting traction, ensuring the continuity and effectiveness of treatment. Furthermore, the overall height of the main beam 1 of the bed frame can be adjusted at four points via electric lifting columns. When the main beam 1 of the bed frame is in a low position of about 50cm, it is suitable for doctors to perform fine spinal adjustments while sitting. When it is in a middle position of about 70cm, it is suitable for doctors to perform lumbar massage and foot massage while standing. When it is in a high position of about 85cm, it is convenient for doctors to use gravity to perform traction and shaking techniques. It is not limited to one or two usage scenarios, so we will not elaborate further. Throughout the traction treatment, the travel limit switch 806 monitors the travel of the sliding block 803 in real time. When the sliding block triggers the limit, the system immediately stops and performs a reverse unloading operation. The tension sensor 704 monitors the traction force value throughout the process. When the tension exceeds the safety upper limit threshold, it also immediately triggers the emergency stop protection, simultaneously stopping the drive motor 802 and quickly unloading the force to avoid iatrogenic damage caused by excessive traction. Furthermore, the rigid components of the aforementioned devices are preferably made of 316L medical-grade stainless steel, medical-grade PEEK, or high-strength medical-grade aluminum alloy. These materials have good biocompatibility, corrosion resistance, and can withstand wiping and disinfection with alcohol and chlorine-containing disinfectants, meeting the requirements for use in hospitals.
