Description

Technical Field

[0001] The utility model relates to a cervical vertebra treatment tool, in particular to a traction device which is convenient for adjusting traction force. Background Art

[0002] Traction is based on the principle of action and reaction, and uses manipulation, instruments or electric devices to generate external force on the human spine or limb joints, so that the tissues are separated to a certain extent and the soft tissues around the joints are appropriately stretched, thereby achieving the purpose of treatment. The existing traction device that is easy to adjust the traction force 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 effect of traction on the cervical spine.

[0003] For example, the utility model with application number CN202321327698.9 discloses a cervical traction device, including a seat, a vertical stand at the rear side of the seat, a transverse support frame connected to the upper end of the vertical stand, the front end of the transverse support frame faces the front side of the seat, a lifting mechanism is arranged at the front end of the transverse support frame, the lifting mechanism is connected to a suspension rope, the lower end of the suspension rope is connected to a suspension seat, the lower side of the suspension seat is connected to a head support, the center of the head support is opened to allow the head to pass through, the front side of the hole is used to support the front mandible, and the rear side of the hole is used to support the rear headrest. The cervical traction device has the advantages of scientific design and simple operation, and is suitable for auxiliary treatment of cervical vertebrae.

[0004] In the prior art, most traction devices use a counterweight or a dynamometer to adjust the magnitude of the traction force. The traction force remains unchanged during the traction process. After the traction is completed, the doctor or patient releases the traction force by loosening a locking mechanism, such as a ratchet, so that the patient's head can be removed from the support cloth. Although these locking mechanisms can ensure that the traction force does not change during the traction process, these mechanisms are mostly set under or on one side of the seat cushion. The traction personnel generally cannot see directly during the traction process, and most of them need to rely on touch to find and then operate. During the traction process, it is inevitable that the patient suddenly feels uncomfortable and cannot continue the traction. This sudden situation may not be very smooth when the patient releases the traction force, which can easily make the patient feel very uncomfortable. Utility Model Content

DETAILED DESCRIPTION

[0021] 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.

[0022] Figures 1 to 4 Shown is an embodiment of the utility model.

[0023] Example:

[0024] A traction device that is convenient for adjusting traction force comprises a base 1, a seat cushion 2 is arranged on the upper side of the base 1, a column 3 is vertically arranged on one side of the base 1, a counterweight device is installed on one side of the column 3, a cross bar 4 is installed on the top of the column 3, a first pulley 5 and a second pulley 6 are respectively arranged at both ends of the cross bar 4, a traction rope 7 is connected to the counterweight device, and the end of the traction rope 7 away from the counterweight device successively passes around the first pulley 5 and the second pulley 6 and is connected to a support cloth 8 below the cross bar 4, the column 3 comprises a fixed rod 36 and a movable rod 37, a sliding hole 38 is arranged on the upper end of the fixed rod 36, a clamping hole 39 connected to the sliding hole 38 is arranged on the side of the fixed rod 36, a clamping block 40 is slidably arranged in the clamping hole 39, the lower end of the movable rod 37 is inserted into the sliding hole 38, the upper end of the movable rod 37 is connected to the cross bar 4, and a clamping groove 41 is arranged on the side of the lower end, and when the clamping groove 41 and the clamping hole 39 are aligned, the end of the clamping block 40 is clamped in the clamping groove 41. During normal traction treatment, the lower end of the movable rod 37 can be fixed at a high position in the sliding hole 38 by the clamping block 40 clamped in the clamping hole 39 and the clamping slot 41. When the cervical traction needs to be quickly canceled, the lower end of the movable rod 37 can be dropped a certain distance in the sliding hole 38 by removing the clamping block 40 from the clamping slot 41, so that the traction rope 7 can be loosened, thereby quickly canceling the traction. When the cervical traction is performed, the column 3 is arranged around the patient's line of sight, so that the patient can quickly operate the clamping block 40.

[0025] A rotating block 42 is arranged above the clamping hole 39 on the side of the fixed rod 36, and a rotating shaft 43 is arranged on one side of the rotating block 42. The rotating shaft 43 is rotatably connected to a rotating rod 44. The lower end of the rotating rod 44 is connected to the clamping block 40, and the upper end is connected to the fixed rod 36 through a first spring 45. With such a configuration, when the traction needs to be canceled, the patient only needs to press the upper end of the rotating rod 44, so that the rotating shaft 43 will drive the clamping block 40 to move in the clamping hole 39, so that the clamping block 40 moves out of the clamping slot 41, and the movable rod 37 will naturally fall down. By providing the first spring 45, the clamping block 40 will not easily slide out of the clamping slot 41 during normal use.

[0026] A bottom frame 46 is provided on one side of the base 1, and the lower end of the fixing rod 36 is connected to the bottom frame 46, and a diagonal brace 47 connected to the fixing rod 36 is provided on the bottom frame 46. By providing the bottom frame 46, the column 3 can be provided on one side of the base 1, so that when the patient sits on the cushion 2, there is no column 3 blocking the front and back sides of the patient, and the patient will not hit the head when the doctor performs vertebral reduction treatment. By providing the diagonal brace 47, a good support force can be provided to the column 3 to prevent the column 3 from tilting.

[0027] 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 locking 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 8, 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 8 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 8.

[0028] The stopper includes a fixed block 24, a second spring 25 and a stopper column 26. The fixed block 24 is mounted on the upper end of the second elongated hole 16. The fixed 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 second 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 second spring 25. With the elastic force of the second spring 25, the tooth opening 28 is always matched with the ratchet 23, so that the ratchet 23 can only rotate in one direction.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] Although the utility model is described herein with reference to a plurality of illustrative embodiments of the utility model, it should be understood that those skilled in the art may devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the disclosure, drawings, and claims of the present application, various modifications and improvements may be made to the components and / or layout of the subject combination layout.
