Description

Technical Field

[0001] The utility model relates to a cervical vertebra treatment tool, in particular to a cervical vertebra traction device. Background Art

[0002] Traction is based on the principle of action and reaction. It uses manipulation, instruments or electric devices to generate external force on the human spine or limb joints, causing a certain separation of tissues and proper stretching of the soft tissues around the joints, thereby achieving the purpose of treatment. The existing cervical traction device uses a connecting rope to connect a belt-like object to wrap and support the patient's lower jaw, and pulls the head upward to achieve the cervical traction effect.

[0003] For example, the utility model with application number CN202221023687.7 discloses a cervical suspension traction device, including a seat, a first support rod, a support foot, a locking ring, a second support rod, and a guide seat. The beneficial effects of the utility model are as follows: a support foot of a cross-shaped structure is horizontally welded and fixed at the bottom of the first support rod in the device, and a locking ring of a U-shaped structure is screwed and connected on the side wall of the seat, so that the user can quickly connect and disassemble the overall structure composed of the first support rod and the second support rod with the seat, a gap is vertically provided at the center of the seat in the device, and a guide wheel is rotatably connected in the gap, and the suspension rope can be turned at the top of the second support rod through the guide wheel, and the suspension rope in the device is connected to a connecting seat, and a tension counting plate of a rectangular structure is limited in the connecting seat and can be slid up and down, and a tension spring is fixed between the bottom of the tension counting plate and the connecting seat, so that the user can intuitively observe the tension of the suspension through the tension counting plate.

[0004] As in the utility model mentioned above, in the prior art, most cervical traction devices are provided with a column to enable the belt (tie cloth) wrapped around the patient's lower jaw to provide traction to the patient's cervical spine vertically upward. When the patient is undergoing traction treatment, he usually leans against the column or faces the column for traction treatment. Under static traction, it can be used normally, but with the current development of cervical vertebrae treatment, doctors will reset the cervical spine during traction, or massage the muscle groups around the cervical spine, and perform related treatments. When the doctor resets the cervical spine, the patient's head will be pushed forward, but based on the fact that most of the front is a column in the prior art, the doctor usually pushes to the side to avoid the patient's head hitting the column. Although this can also achieve a reset effect, the effect is reduced compared to straight-line propulsion, and sideways push is also easy to hit the column, causing unnecessary harm to the patient.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Figures 1 to 3 Shown is an embodiment of the utility model.

[0021] Example:

[0022] A cervical traction device comprises a base 1,

[0023] A seat cushion 2 is installed on the upper side of the base 1, and bottom rods 3 are arranged on the left and right sides of the base 1. Vertical rods 4 are vertically arranged on the upper sides of the two bottom rods 3. The top ends of the two vertical rods 4 are connected by a horizontal rod 5, and a sliding hole penetrating the upper and lower sides is arranged in the middle of the horizontal rod 5. A counterweight device is installed on the side of the vertical rod 4, and a first pulley 6 is arranged on the upper end of the vertical rod 4 above the counterweight device, and a second pulley 7 is arranged on the upper side of the horizontal rod 5 at the position of the sliding hole. A traction rope 8 is connected to the counterweight device, and the end of the traction rope 8 away from the counterweight device successively passes around the first pulley 6, the second pulley 7 and the sliding hole, and then a support cloth 9 is connected under the horizontal rod 5 through the two vertical rods 4 and the horizontal rod 5. The support cloth 9 is placed between the two vertical rods 4. In this way, when the patient sits on the seat cushion 2, there are no columns blocking the front and back sides of the patient, and the patient will not hit his head when the doctor performs vertebral reduction treatment. Through the first pulley 6 and the second pulley 7, the support cloth 9 and the counterweight device can be connected through the traction rope 8 to provide vertical upward traction.

[0024] The counterweight device includes a counterweight box 10, a counterweight block 11 and a lifting column 12. A counterweight cavity 13 is vertically arranged in the counterweight box 10. A wire hole 14 connected to the counterweight cavity 13 is arranged at the upper end of the counterweight box 10. The first long hole 15 and the second long hole 16 are vertically arranged on opposite sides of the counterweight box 10 near the upper end. The first long hole 15 and the second long hole 16 are aligned. The counterweight block 11 is installed at the bottom of the counterweight cavity 13. The lower part of the lifting column 12 is connected to the counterweight block 11. The upper end of the lifting column 12 is connected to a horizontal plate 17, and the horizontal plate 17 faces the first long hole 15 and the second long hole 16. Both ends of the hole 16 are vertically provided with rotating plates 18, and the two rotating plates 18 are respectively provided with a first rotating hole 19 and a second rotating hole 20, and a rotating shaft 21 is rotatably provided between the two rotating plates 18, and one end of the rotating shaft 21 passes through the first rotating hole 19 and the first long hole 15 in sequence, and is connected to a knob handle 22 on the outside of the counterweight box 10, and the other end of the rotating shaft 21 passes through the second rotating hole 20 and the second long hole 16 in sequence, and is connected to a ratchet 23 on the outside of the counterweight box 10, and a stop claw matching the ratchet 23 is provided on the outside of the counterweight box 10; the traction rope 8 is connected to the middle of the rotating shaft 21. When traction is performed, the patient fixes his head on the support cloth 9, and then the doctor rotates the knob handle 22 to gradually wrap the traction rope 8 around the rotating shaft 21, so that the support cloth 9 is gradually pulled upward, which has a traction effect on the patient's cervical spine. As the traction rope 8 is gradually wound around the rotating shaft 21, the rotating shaft 21 will move upward, and at the same time, the counterweight 11 will be lifted by the lifting column 12, so that the counterweight 11 will leave the bottom of the counterweight cavity 13, so that the traction force is applied to the patient's cervical spine with the help of the counterweight 11. With the help of the stop pawl and the ratchet 23, the rotating shaft will only rotate in one direction when rotating, and will not rotate back. In this way, during the traction process, the traction rope 8 will not be loosened from the rotating shaft 21 due to the rotation of the rotating shaft 21, resulting in the counterweight 11 being unable to produce a traction effect on the support cloth 9.

[0025] The stopper pawl comprises a fixing block 24, a spring 25 and a stopper column 26. The fixing block 24 is mounted on the upper end of the second elongated hole 16. The fixing block 24 is provided with a telescopic slot 27 with an opening facing downward. The lower end of the stopper column 26 is provided with a tooth opening 28 matching the ratchet 23. The upper end of the stopper column 26 is slidably arranged in the telescopic slot 27. One end of the spring 25 is connected to the bottom of the telescopic slot 27, and the other end is connected to the upper end of the stopper column 26 in the telescopic slot 27. With such a configuration, when the rotating shaft 21 carries the breeding block, it will move up along the first elongated hole 15 and the second elongated hole 16 by one end, so that the counterweight block 11 leaves the bottom of the counterweight cavity 13. In the process of the rotating shaft 21 moving up, the ratchet 23 will push the stopper column 26 to move up and compress the spring 25. With the elastic force of the spring 25, the tooth opening 28 is always matched with the ratchet 23, so that the ratchet 23 can only rotate in one direction.

[0026] A toggle lever 29 is horizontally arranged on the side of the stop post 26. By setting the toggle lever 29, after the traction is completed, the stop post 26 can be driven to move upward by moving the toggle lever 29 upward, so that the tooth mouth 28 and the ratchet 23 are separated, so that the ratchet 23 can rotate in the opposite direction, so that the traction rope 8 wound on the rotating shaft 21 can be loosened.

[0027] The middle of the counterweight 11 is provided with a through hole 30 that passes through the upper and lower sides, and the side of the counterweight 11 is provided with an insertion hole 31 that is connected to the through hole 30. A plug 32 is detachably provided in the insertion hole 31, and the side of the lifting column 12 is provided with an insertion groove 33 that matches the insertion hole 31. When the insertion groove 33 is aligned with the insertion hole 31, the plug 32 is inserted into the insertion groove 33. When traction is needed, the plug 32 is inserted into the insertion groove 33, and the counterweight 11 and the lifting column 12 can be connected together with the help of the plug 32. With the help of the cavity wall of the counterweight cavity 13, the lifting column 12 and the counterweight 11 can move up and down together, thereby applying traction to the patient.

[0028] Several counterweight blocks 11 are stacked in the counterweight cavity 13, and several insertion slots 33 are matched on the side of the lifting column 12; the side of the counterweight box 10 is provided with a selection hole 34 connected to the side of the counterweight cavity 13. By setting a plurality of counterweight blocks 11, it is possible to adjust the appropriate matching according to different needs and apply different weights of traction to the patient. When adjusting, it is only necessary to insert the pin 32 into the insertion hole 31 on different counterweight blocks 11, and then pass through the insertion hole 31 to connect with the insertion slot 33 on the lifting column 12, so that when the lifting column 12 is raised, it can drive all the counterweight blocks 11 above the pin 32.

[0029] A strengthening support rod 35 is provided at the lower end of the base 1, one end of the strengthening support rod 35 is connected to the base 1, and the other end is connected to the connection between the bottom rod 3 and the vertical rod 4. By providing the strengthening support rod 35, a good auxiliary support effect can be played on the vertical rod 4, and moreover, the end of the strengthening support rod 35 away from the base 1 can be moved upward to be connected to the lower part of the vertical rod 4.
