The downward movement of the traction rack 42 drives the buffer plate 71 downward, and the downward movement of the buffer plate 71 drives the second one-way plate 76 and the second connecting shaft 77 to rotate, so that the gas inside the buffer groove 11 is discharged, so that the buffer plate 71 can move down slowly; rapid contact traction is achieved when the patient feels uncomfortable, so that collision and friction will not occur too quickly when the cervical vertebra is repositioned, thereby ensuring the safety of the patient's spine.

[0040] Specifically, the wedge-shaped sliding plate 57 is in abutment with the wedge-shaped block 58 .

[0041] Specifically, the release mechanism 6 includes a trapezoidal block 61, two release springs 62 and two L-shaped switching rods 63.

The trapezoidal block 61 is slidably arranged on the top of the support ring 1. The ends of the two L-shaped switching rods 63 are respectively limited and slidably matched with the side walls of the corresponding traction racks 42. The two L-shaped switching rods 63 are both provided with dislocation grooves 12. By pressing the trapezoidal block 61 to resist the movement of the two L-shaped switching rods 63, the movement of the L-shaped switching rods 63 drives the corresponding traction racks 42 to move synchronously, and the movement of the traction racks 42 is dislocated with the traction gear 44, so that the traction ring 2 can quickly contact the traction force; it is realized that the patient can quickly release the traction by himself, which is highly safe, simple to operate, and convenient and fast.

[0042] A method for using a traction device for clinical orthopedic use:

[0043] S1: First, the support ring 1 is put on the patient's shoulder, and then the airbag 3 is inflated to initially fix the patient's mandible;

[0044] S2: Then, according to the doctor's advice, when continuous traction is required, the position of the traction ring 2 is adjusted by the traction mechanism 4, thereby adjusting the traction strength;

[0045] S3: When intermittent traction is required, the adjusting mechanism 5 works, and the adjusting mechanism 5 cooperates with the traction mechanism 4 and the traction ring 2 to perform intermittent traction treatment on the patient's cervical spine;

[0046] S4: When the patient feels discomfort during the traction process, the release mechanism 6 can be pressed to quickly release the traction force, and under the action of the buffer mechanism 7, the patient's cervical spine can be released from the traction force and slowly reset.

[0047] Working principle: First, put the support ring 1 on the patient's shoulder, then inflate the airbag 3 to initially fix the patient's mandible, and then according to the doctor's order, when continuous traction is needed, the medical staff rotates the plug rod 48 to drive the turntable 49 to rotate, and the rotation of the turntable 49 drives the rotating shaft 45 and the traction gear 44 to rotate, and the rotation of the traction gear 44 drives the traction rack 42 to move up, and the upward movement of the traction rack 42 drives the sleeve rod 43 to move up, and the upward movement of the sleeve rod 43 drives the traction ring 2 to move up to traction the patient's cervical spine, and after adjusting to the appropriate traction force, press the plug rod 48 so that the plug rod 48 is inserted into the plug slot 47 to fix it. The traction force is provided to realize continuous traction. When intermittent traction is needed, the second bevel gear 54 is driven to rotate by adjusting the output shaft of the motor 512. The second bevel gear 54 drives the first bevel gear 53 to rotate. The first bevel gear 53 drives the transmission shaft 51 and the cam 52 to rotate. The rotation of the cam 52 drives the sleeve rod 43 to lift or lower, thereby realizing the effect of intermittent traction. In addition, as the traction rack 42 moves upward, the fixed plate 59 and the L-shaped plate 55 move upward synchronously. The L-shaped plate 55 moves upward and drives the wedge-shaped sliding plate 57 to move upward. While the wedge-shaped sliding plate 57 moves upward, it cooperates with the action of the adjusting spring 510 to move along the The track of the inclined groove 56 moves, thereby driving the adjusting motor 512 and the second bevel gear 54 to move synchronously, changing the meshing position of the first bevel gear 53 and the second bevel gear 54, changing the rotation speed of the first bevel gear 53, thereby changing the traction time and the traction interval length. When the patient feels uncomfortable during the traction process, the trapezoidal block 61 can be pressed to contact the two L-shaped switching rods 63 to move. The movement of the L-shaped switching rod 63 drives the corresponding traction rack 42 to move synchronously. The movement of the traction rack 42 is misaligned with the traction gear 44, so that the traction ring 2 quickly contacts the traction force, and when the traction is passed The sliding of the guide rack 42 drives the T-bar on the buffer plate 71 to slide, so that the traction rack 42 and the traction gear 44 are disengaged, thereby automatically moving the traction ring 2 downward along the buffer groove 11 under the action of gravity. The downward movement of the traction rack 42 drives the buffer plate 71 downward, and the downward movement of the buffer plate 71 drives the second one-way plate 76 and the second connecting shaft 77 to rotate, so that the gas inside the buffer groove 11 is discharged, so that the buffer plate 71 can move downward slowly, and the slow downward movement of the buffer plate 71 allows the buffer rack and the traction ring 2 to move downward slowly as well, ensuring that the patient's cervical spine can be released from the traction force and slowly reset at the same time.
