Description

Technical Field

[0001] The invention relates to the technical field of physical cervical traction, in particular to a cervical traction device. Background Art

[0002] The cervical spine is part of the human spine, located between the head and the chest. It is composed of 7 cervical vertebrae (C1 to C7). The main function of the cervical spine is to support the weight of the head, protect the spinal cord and nerve roots, and allow the head to perform various movements.

[0003] In the prior art, a cervical vertebra fixing and traction device disclosed in Chinese patent announcement number: CN118750250A includes an adjusting support assembly, the top of the adjusting support assembly is fixedly connected to a bed assembly, and a traction and stretching assembly and a control assembly are arranged on the top of the bed assembly. The present invention drives the first gear to engage with the bevel gear body by utilizing a transmission structure composed of a motor-driven rotating wheel, a belt and a transmission wheel combination, so that the second gear, the third gear and the fourth gear are engaged and rotated at the same time, and then the fourth gear is threadedly moved on the screw rod, and the connecting plate pulls the elastic rod to perform cervical traction on the patient's head placed on the fixing sleeve.

[0004] However, the above patents have the following deficiencies:

[0005] The device involved in this patent improves the traditional structural layout, uses multiple mechanical components to coordinate, applies external force to the lower jaw, and reasonably controls the traction force according to the actual situation to achieve the lifting and training of the cervical spine. However, the shortcomings are specifically manifested as follows:

[0006] 1) Although the device has the ability to adjust in real time, it does not change the nature of external force intervention. Patients who need traction often have varying degrees of damage to their cervical spine. This type of traction will aggravate neck pain after long-term use, and intermittent use cannot improve the traction effect.

[0007] 2) The device is adapted for a single mode of use and cannot reasonably change the traction mode according to the condition of each patient, which reduces the diversity of device use and increases the limitations of device use.

[0008] Therefore we propose a cervical traction device to solve the above-mentioned problems. Summary of the invention

During the pulling process of the skin, the muscles under the cortex will be in a stretched state. With the lifting direction of the component, the patient's head may show a tendency to lean back. Each time the action is completed, the cervical vertebrae are temporarily straightened. The relevant modules of the system successively control the resetting and lifting of each collaborative component to simulate the artificial neck unblocking effect, which is conducive to the control of external force and avoids the cervical vertebrae being in a physically straightened state all the time, so as to solve the problems raised by the above-mentioned background technology.

Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] according to Figure 4 and Figure 5As shown, a T-shaped slide 405 is movably inserted inside each inner open slide 402, a merging support plate 406 is fixedly installed between the rear surfaces of the two T-shaped slides 405, a first machine-changing component 407 is fixedly installed on the rear surface of the merging support plate 406, and a transmission rod 408 is fixedly connected to the output end of the first machine-changing component 407, and a connecting frame 409 is fixedly sleeved on the outer wall of the transmission rod 408, and the connecting frame 409 is connected to the rear surface of the driving gear 404. By presetting the above components, the mechanism adopts mechanical gear transmission. During the working process, the motor and the meshing transmission will produce a certain amount of shaking, which will cause the position deviation of the connected components on the one hand, and will make the power output unstable on the other hand. Then, the above components are coordinated to effectively reduce the shaking amplitude, reduce the position deviation of components, and increase the subsequent cervical vertebra lifting effect.

[0038] according to Figure 4 and Figure 5 As shown, a hollow shell 426 is fixedly installed on the opposite side of the two first solid bases 401, and two limit frames 425 are fixedly installed on the rear surface of the assembly support plate 413. Each limit frame 425 is movably placed inside a corresponding hollow shell 426. By presetting the above components, this part of the limiting component can cooperate with the rear end limiting component to stabilize the driving component and the lifting component respectively.

[0039] according to Figure 5 As shown, a rectangular frame 427 is fixedly installed on the front surface wall of the L-shaped frame 421, and a first leather pad 428 is fixedly installed inside the rectangular frame 427. By presetting the above components, the patient's head will shake back and forth during the lifting process of the mechanism. When the patient's head moves backward, the top of the head will first contact the rear sensing component 424, and the back of the head can be protected by the first leather pad 428 to prevent collision with hard objects and avoid damage to the skull.

[0040] according to Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the segmented adjustment mechanism 5 includes two sub-shells 501, which are respectively fixedly mounted on both sides of the outer wall of the main shell 1, and an annular sleeve 502 is fixedly mounted on one side of the outer wall of each sub-shell 501, and a damping turntable 503 is movably provided inside each annular sleeve 502, and an external base 504 is fixedly inserted inside each damping turntable 503, and a docking frame 505 is fixedly mounted on the outer wall of each external base 504, and the top of each docking frame 505 is connected to the bottom of the associated cross plate 2. By presetting the above components, the driving component can be used to directly transmit power to the damping turntable 503, and by rotating 90° counterclockwise, the docking frame 505 and its connected parts are driven to rotate slowly until the docking frame 505 is flush with the main shell 1, thereby flattening the first extended tray 3 to complete the replacement of another traction method.

[0041] according to Figure 7 As shown, an external frame 506 is fixedly installed on one side of the outer wall of each sub-shell 501, and a second machine-changing component 507 is fixedly installed on the outer wall of each external frame 506. The shaft end of each second machine-changing component 507 is respectively fixedly inserted into the interior of a corresponding external base 504. By presetting the above components, the second machine-changing component 507 includes a motor and a reducer, so the processed power is low speed and high torque, ensuring that the connected components can be fully adjusted into place.

[0042] according to Figure 7 and Figure 8 As shown, a second extension tray 508 is movably inserted inside the main shell 1, a third extension tray 510 is movably inserted inside each sub-shell 501, pneumatic components 511 are fixedly installed on opposite sides of the two sub-shells 501, and grafting plates 512 are fixedly installed on opposite sides of the two third extension trays 510. The axial ends of each pneumatic component 511 are respectively fixedly inserted inside a corresponding grafting plate 512. By presetting the above components, this part of the components is mainly used for equipment height adjustment, and the distance between the equipment and the ground can be reasonably controlled according to the traction method to ensure that the three traction methods achieved can be carried out under relatively comfortable conditions.

[0043] according to Figure 7 and Figure 8 As shown, two inner slots 513 are provided at the bottom of the main shell 1, and two locking frames 514 are fixedly installed at the bottom of the main shell 1, and a second electric component 515 is fixedly installed inside each locking frame 514, and two second solid bases 516 are fixedly installed at the bottom of the second extended support plate 508, and each second solid base 516 is movably placed inside the inner slot 513, and the axial end of each second electric component 515 is fixedly inserted into the inside of a corresponding second solid base 516. By presetting the above-mentioned components, utilizing the movable connectivity between the main shell 1 and the second extended support plate 508, and coordinating the mutual coordination of these components, the docking frame 505 can be freely extended and retracted inside the main shell 1, which can realize the change of traction mode on the one hand, and avoid restrictions on different traction modes on the other hand.

[0044] according to Figure 7 and Figure 8 As shown, a second leather pad 509 is provided on the top of the second extension tray 508, a rectangular groove 517 is provided on the front surface of each first extension tray 3, and a third leather pad 518 is fixedly installed inside each rectangular groove 517. By presetting the above components, the second leather pad 509 and the third leather pad 518 can provide support for the patient's buttocks and waist and improve the patient's comfort.

[0045] according to Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, two first solid bases 401 are respectively fixedly mounted on the rear surface of a corresponding first extended pallet 3, a metal clamping sleeve 6 is fixedly mounted on the bottom of each third extended pallet 510, two fourth extended pallets 7 are mounted inside each metal clamping sleeve 6, and a group of variable support feet 8 are installed inside each fourth extended pallet 7.

[0046] The effect achieved by the entire mechanism is as follows: in the preparation stage, the equipment is first moved to the designated working area, and the bottom of each variable support foot 8 is fully in contact with the ground, each variable support foot 8 is adjusted in turn, the equipment height is initially set, and then the external line is connected to the equipment power supply, in order to provide energy for multiple electrical components therein.

[0047] Traction method 1: synchronously open the pneumatic component 511 to extend its inner axis outward, and use the movable connection between the sub-shell 501 and the third extension support plate 510 to drive each third extension support plate 510 to move slowly downward, gradually extending each third extension support plate 510 from the corresponding sub-shell 501, and continuously increasing the height of the device from the ground. After the height is determined, the patient can stand in front of the device with his head covered in the silicone head cover 422. When the patient's neck is in a relaxed state, the head is in a forward tilted state, so that the forehead is fully in contact with the front sensing component 423, and the first mechanical change component 407 is opened, and the device system model The block controls the rotation direction of the first machine-variable component 407, and acts on the transmission rod 408 and the connecting frame 409 to directly transmit the low-speed and high-torque power to the driving gear 404. By utilizing the movable connectivity between the inner open slide 402 and the T-shaped slide seat 405, and the meshing connectivity between the bar teeth 403 and the driving gear 404, the components connected to the driving gear 404 can be driven to move up and down back and forth in front of the first extended support plate 3. During the process, the physical properties of the roller bearing 410 itself, as well as the position limitation of the limit frame 425 and the hollow shell 426 are utilized to ensure that the assembly support plate 413 and its connected components will not be offset.

[0048] The traction process is to raise the height of the U-shaped joint 416 so that a silicone sleeve 419 at the bottom is flush with the top of the cervical vertebra, turn on the first electric component 412, slowly push the assembly support plate 413 and its connected components toward the patient's neck until a silicone sleeve 419 is fully fitted with the neck skin, and the extension length of the traction component is determined by the inner width distance of the hollow shell 426. Turn on the first variable component 407, accurately control the rotation direction, drive the U-shaped joint 416 to move slowly downward, and use the movable connection between the cross bar 417 and the U-shaped joint 416. Each roller rod 418 can roll synchronously under the friction between the silicone sleeve 419 and the skin to pull the back of the neck from top to bottom. The skin and muscles of the patient's head will be pulled back when the patient is in a relaxed state. At the same time, the cervical vertebrae can be pulled up once and be in a stretched state for a short time. After each muscle pulling, the relevant components can be quickly reset and the cervical vertebrae will be repeatedly stretched. When the head is tilted back to the maximum range, the frontal bone will first contact the rear sensing component 424, and then the occipital bone will accurately contact the first leather pad 428. The judgment basis of the relevant modules of the equipment system is to monitor the signal fed back by the rear sensing component 424 in real time. If no signal feedback appears for many times, the first electric component 412 will further push the traction component to increase the contact strength between the silicone sleeve 419 and the skin and improve the muscle stretching strength.

[0049] Traction method two, by opening the pneumatic component 511, the inner axis is retracted into the cavity, driving the third extension tray 510 to reset, lowering the height of the equipment from the ground, and synchronously opening each second electric component 515 to extend the inner axis outward, and utilizing the movable connection between the main shell 1 and the second extension tray 508 and the inner groove 513 and the second solid base 516 to drive the second extension tray 508 to withdraw from the interior of the main shell 1, and make the second leather pad 509 fully exposed. The patient can use the above method to perform cervical traction while sitting or standing.

[0050] Traction mode three, reset the second extended support plate 508, and synchronously open the two second machine-variable components 507. The counterclockwise low-speed power generated directly acts on the damping turntable 503, driving the docking frame 505 and its connected components to rotate 90°, forcing the docking frame 505 to be flush with the main shell 1. At this time, the associated cross plate 2 can be fully aligned with the rear surface of the main shell 1, and the above-mentioned traction method can be used to allow the patient to lie flat to complete cervical traction.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
