[0002] A spinal traction device is a medical device used to treat the spine. It stretches the intervertebral space and intervertebral foramen through traction, relieves symptoms such as pain, numbness and radiating pain caused by nerve root compression, and can also help restore the normal physiological curvature of the spine and correct spinal deformities caused by bad posture or disease, such as reduced cervical lordosis. Existing spinal traction devices are usually equipped with an adjustable fixing belt for fixing to the head and neck. The fixing belt is usually made of soft and breathable materials, such as cotton or elastic fabric, to ensure comfortable wearing. When in use, the bracket on the fixing belt is fixed to the head and neck, and the fixing belt is pulled up by the traction device to achieve traction on the neck.

Detailed implementation manners

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0029] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0031] Existing traction devices usually consist of a driving device and a fixing belt. A neck support plate is provided on the fixing belt. During use, the neck support plate is fixed to the neck, and the driving device pulls up the fixing belt to traction the neck. The stress point of the traditional traction method is located on the neck. By squeezing the chin and neck tissues to lift the lower jaw, the head is lifted to traction the neck, which is likely to cause compression of the neck blood vessels. There is a greater risk for patients with vascular sclerosis to use, and users are prone to strong discomfort and even difficulty in breathing. The spinal traction device provided in this application adopts a telescopic traction structure and uses a molar support plate to traction the head, transferring the stress point to the molars, cleverly avoiding the compression of the neck blood vessels and muscles, ensuring that patients with vascular sclerosis can also use it safely, greatly enhancing the comfort of use, and not compressing the respiratory tract, ensuring smooth breathing of the user, and fundamentally eliminating the potential safety risks during the use of traditional traction devices.

[0032] Please refer to the appended Figure 1 to the appended Figure 12, the spinal traction device provided by the present invention is now described. The spinal traction device includes a main frame 05, a sliding member 10, a lifting mechanism, a molar support plate 12 and a first strap 11. The sliding member 10 is raised and lowered relative to the main frame 05, and the molar support plate 12 is supported at the molar position to apply traction force to the molar and premolar area of ​​the upper jaw to lift the head upward. Specifically, the sliding member 10 is slidably connected to the main frame 05 in the vertical direction. The lifting mechanism is used to drive the sliding member 10 to slide. The molar support plate 12 is fixedly connected to the sliding member 10, and the molar support plate 12 has a supporting portion for being placed in the oral cavity to support the molars. The first strap 11 is fixedly connected to the sliding member 10, and the first strap 11 is used to bind the user's head to the sliding member 10 to prevent the head from shifting during traction and causing strain. Furthermore, the first strap 11 is fixed in the following manner: a buckle is fixed on the sliding member 10, and both ends of the first strap 11 pass through the buckle, so that the first strap 11 forms a ring structure suitable for binding the head in front of the sliding member 10, and the tightness of the first strap 11 is adjusted by adjusting the length of the first strap 11 passing through the buckle. When in use, the sliding member 10 is adjusted to a suitable height, and the user puts the molar support plate 12 into the oral cavity so that it can support the molar area upward, and then uses the first strap 11 to bind the head to the sliding member 10, and drives the sliding member 10 to rise through the lifting mechanism, thereby driving the neck to be pulled upward.

[0054] When using the spinal traction device provided by the present invention for cervical spine traction, its usage method includes the following steps: S1. Put the molar tray 12 into the user's oral cavity and fix the user's head on the sliding member 10 with the first strap 11; S2. Lift the slider 10 so that the molar tray 12 abuts against the user's upper molars and pulls upward.

[0055] By using the above method, there is no need to compress the neck blood vessels and neck muscles during the traction process, nor will there be a sense of suffocation, greatly improving the comfort and safety of the traction.

[0056] Before performing the steps of S1, first adjust the height of the main body bracket 05, raise the support slide bar to a height suitable for fixing the head, and install fixing bolts in the first limit hole of the bottom tube and the second limit hole of the support slide bar to fix the support slide bar.

[0057] In S1, adjust the height of the slider 10 to ensure that the molar tray 12 can contact the upper jaw molars or some premolars. When fixing the head, loosen the first strap 11, put the molar tray 12 into the oral cavity, move the head so that the upper jaw molars and premolars are placed on the molar tray 12, adjust the lower positioning member 14 to make it contact the front part of the upper jaw, and the user's forehead contacts the upper positioning member 13. Then tighten the first strap 11 to bind the head to the slider 10.

[0058] In S2, in an alternative embodiment, the user can control the upward lifting of the slider 10 by rotating the handwheel 15, so as to achieve the traction effect. The handwheel 15 drives the limit tube 22 to rotate. Through the cooperation of the limit tube 22 and the limit block 201, the screw 20 is driven to rotate. The screw 20 is in threaded cooperation with the connecting member 21, thereby driving the slider 10 to lift.

[0059] In another alternative embodiment, the user can choose the traction method driven by the motor 01. The motor 01 drives the screw 20 to rotate, and then drives the slider 10 to lift.

[0060] In the above embodiment, when performing cervical traction with the spinal traction device, the user can use it while standing or can sit on a self-provided stool or chair.

[0061] When using the spinal traction device provided by the present invention for thoracic and lumbar traction, the usage method includes the following steps: S1. The user grabs the handle 17 and leaves the ground with both feet, or binds the second strap 08 under the armpits and bends the knees or leaves the ground with both feet; S2. Turn on the vibration motor 03 to apply vibration traction to the user.

[0062] By using the above method, a certain frequency of vibration is applied during the traction by the vibration motor 03. Only a lower traction force is required, and a good traction effect can still be achieved, reducing the risk of strain caused by excessive traction force.

[0063] Before performing the steps of S1, adjust the main bracket 05 to an appropriate height. The specific steps are the same as the adjustment method of the main bracket 05 in the above cervical traction method, so they will not be repeated here.

[0064] In S1, if traction is performed through the gripper 17, the user steps on the pedal 09 and grabs the gripper 17, and then leaves the pedal 09 and hangs in the air.
