Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and in particular relates to a self-help reduction device for thoracic facet joints. Background Art

[0002] The facet joints of the thoracic spine can become dislocated and disordered in the front-to-back direction due to bad sitting and lying habits, accidental injuries, etc., causing chest and back pain, reduced thoracic spine mobility, and a hunched back. The existing methods for resetting the facet joints of the thoracic spine are mainly performed by professional physicians for osteopathic correction. However, since sitting and lying postures are long-term habits, the facet joints of the thoracic spine can be dislocated and disordered in the front-to-back direction, which can easily recur. If you receive treatment from a professional physician every time, it will cost a lot of time and money. Summary of the invention

[0003] The purpose of the present invention is to provide a self-help reduction device for the facet joints of the thoracic vertebrae. After being used under the guidance of a professional physician, the patient can use his / her spare time to independently complete the safe reduction of the facet joints of the thoracic vertebrae, thereby reducing the number of appointments with professional physicians and saving a large amount of treatment costs.

[0004] The present invention is achieved through the following technical solutions:

[0005] A self-help reduction device for thoracic facet joints comprises two support seats arranged in horizontal mirror image and a reduction mechanism arranged between the two support seats; the reduction mechanism comprises a support rod and two reduction bodies, the two ends of the support rod are respectively axially connected to the two support seats, and the two reduction bodies are arranged on the support rod and are symmetrical to each other with the midpoint of the support rod as the center of symmetry.

[0006] Through the above scheme, the present invention at least achieves the following technical effects:

[0007] The reducer is placed on the bed to ensure that the two support seats can stably support the reduction mechanism. The patient lies on his back between the two support seats, with the patient's thoracic spinous process stuck between the two reduction bodies, and the surfaces of the two reduction bodies against the patient's back (i.e., both sides of the spinous process). The patient holds his head with both hands and bends his neck and legs, and puts his feet firmly on the bed to lift his waist and hips. The reducer and feet support the body together, so that the patient's waist and hips are suspended above the bed, and the contact parts of the chest and back with the two reduction bodies are concentrated with force.

[0008] When performing the reduction, the patient's feet remain still, the knees are flexed and extended, and the upper body is moved back and forth horizontally under the support of the two reduction bodies, so as to adjust the contact point between the chest and back and the reduction bodies, and achieve the purpose of adjusting the thoracic vertebral segment to be reduced. Both ends of the support rod are installed on the two support seats through bearings, so that the support rod can rotate, and the two reduction bodies set on the support rod can also rotate freely. When the patient performs horizontal reciprocating motion, rolling friction occurs between the two reduction bodies and the patient's back to reduce resistance. During the patient's horizontal reciprocating motion, the patient can do backward and forward bending of the upper body and head and neck to fine-tune the angle of force and pressure of the reducer.

[0009] Preferably, the two support seats each include a seat body, a strip groove horizontally opened on the side wall of the support seat, and a slider slidably arranged in the strip groove; both ends of the support rod are axially connected to the slider to enable the reset mechanism to move horizontally.

[0010] Preferably, two side walls of the strip-shaped groove are symmetrically provided with limiting grooves, and the edge of the sliding block forms a limiting piece, and the limiting piece can be slidably embedded in the limiting groove.

[0011] Preferably, it also includes a base, and two support bases are installed on the top surface of the base; the base is a flat plate structure.

[0012] Preferably, the base includes a main board and two movable plates; stepped lower splicing grooves are provided on both sides of the main board, and stepped upper splicing grooves are provided on both movable plates, the upper splicing grooves and the lower splicing grooves are mirror images of each other and interlock with each other, and the stepped surfaces of the upper splicing grooves fit and slide with the stepped surfaces of the lower splicing grooves; the stepped surfaces of the lower splicing grooves are provided with T-shaped grooves, and the stepped surfaces of the upper splicing grooves are provided with T-shaped limit blocks; the T-shaped limit blocks slide in the T-shaped grooves so that the two movable plates can slide out or retract to both sides relative to the main board; the two support seats are respectively installed on the two movable plates.

[0013] Preferably, the support rod comprises a main rod body and two telescopic rod bodies; telescopic cavities are provided at both ends of the main rod body, one end of the two telescopic rod bodies is slidably arranged in the telescopic cavity, and the other end is axially connected to the two support seats; two reset bodies are arranged on the main rod body.

[0014] Preferably, two groups of limiting sleeves are further provided on the support rod; the two groups of limiting sleeves are respectively used to fix the positions of the two reset bodies on the support rod.

[0015] Preferably, the support rod and the two reset bodies are integrally formed.

[0016] Preferably, the reset body is in the shape of a sphere or a cone.

[0017] Preferably, the reset body is made of rubber, wood or metal.

[0018] The beneficial effects of the present invention are as follows: the reducer can autonomously perform reduction treatment of the thoracic facet joints, achieving the purpose of relieving chest and back pain and improving thoracic spine mobility similar to the reduction technique of professional doctors. The reducer is small in size, simple in structure, and can be used in any place. It is safe to operate and can be used autonomously at any time, saving the time and medical expenses of frequent medical treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] Embodiment 1:

[0037] like Figure 1 and Figure 2 As shown, a self-help reduction device for facet joints of thoracic vertebrae comprises a base 3, two support seats 1 and a reduction mechanism 2; the two support seats 1 are respectively installed at the edges of both sides of the base 3, and the reduction mechanism 2 is horizontally mounted between the two support seats 1. The patient lies on his back on the reduction mechanism 2 and uses his legs to support the body to perform horizontal reciprocating motion to complete the self-help reduction treatment of facet joints of thoracic vertebrae.

[0038] The two support seats 1 are mounted on the flat base 3, so that the two support seats 1 can be stably kept in a horizontal state, and the height difference between the two support seats 1 can be avoided, so that the contact angle between the reset mechanism 2 and the patient's back is skewed.

[0039] The resetting mechanism 2 includes a support rod 21 and two spherical resetting bodies 22. The two ends of the support rod 21 are mounted on two support seats 1 through bearings so that the support rod 21 can rotate by itself. The two spherical resetting bodies 22 are mounted on the support rod 21 and rotate synchronously with the support rod 21. The two spherical resetting bodies 22 are symmetrical to each other with the midpoint of the length direction of the support rod 21 as the symmetry center. The gap between the two spherical resetting bodies 22 accommodates the spinous process of the patient to prevent the spinous process of the patient from being damaged during the resetting process. The two spherical resetting bodies 22 are in contact with the patient's back. The symmetrical setting can ensure that the force points on both sides of the patient's spinous process are symmetrical, avoiding the problem of resetting deviation caused by the generation of lateral force components.

[0040] The two spherical reset bodies 22 can be replaced by conical reset bodies 22. The center of the spherical reset body 22 is on the central axis of the support rod 21, and the central axis of the conical reset body 22 coincides with the central axis of the support rod 21. The two reset bodies 22 can be made of rubber, wood or metal.

[0041] like Figure 5 As shown, the two reset bodies 22 and the support rod 21 can be made by an integrated manufacturing process, or the support rod 21 can be passed through the two reset bodies 22, and the two reset bodies 22 can be sleeved on the support rod 21. To ensure the stability of the positions of the two reset bodies 22, a limiting sleeve 214 can be used to limit and fix the reset bodies 22. The limiting sleeve 214 can be made of elastic rubber or elastic silicone material in the shape of a ring sleeve, and sleeved on the support rod 21 at both ends of the reset body 22; a threaded sleeve can also be used, and a thread is set on the support rod 21 to form a thread pair to cooperate with it to achieve the purpose of limiting.

[0042] Embodiment 2:

[0043] On the basis of Example 1, the two support seats 1 are improved so that the resetting mechanism 2 can move horizontally on the two support seats 1 to enhance the treatment effect.

[0044] like Figure 3 and Figure 4 As shown, in the two support seats 1, each support seat 1 is composed of a seat body 11, a strip groove 12 horizontally opened on the side wall of the support seat 1 and a slider 13 slidably arranged in the strip groove 12; the slider 13 can slide horizontally in the strip groove 12, and a bearing is embedded in the slider 13. The end of the support rod 21 in the reset mechanism 2 is connected to the bearing, so that the reset mechanism 2 can move horizontally as a whole, and the support rod 21 can rotate at the same time.

[0045] In order to prevent the reset mechanism 2 from being skewed due to the different displacements or lateral movement of the sliders 13 in the two support seats 1 when the reset mechanism 2 moves horizontally, a limit groove 121 is provided on the upper and lower side walls of each strip groove 12, and a limit piece 131 is provided on the outer side wall of each slider 13, so that the limit piece 131 is embedded in the limit groove 121. The moving direction of the two sliders 13 is limited, and at the same time, the two sliders 13 and the limit piece 131 are combined with the support rod 21 to form an "I"-shaped structure, which can prevent the reset mechanism 2 from being skewed in cooperation with the limit groove 121.

[0046] Embodiment 3:

[0047] On the basis of Example 1 or Example 2, the base 3 and the support rod 21 are improved to have a length-adjustable structure, which is suitable for patients of different ages and body shapes.

[0048] like Figure 5 and Figure 6 As shown, the base 3 is composed of a main board 31 and movable plates 32 on both sides. At the joint of the main board 31 and the two movable plates 32, stepped lower joint grooves 311 are arranged on both sides of the main board 31, and stepped upper joint grooves 321 are arranged on the movable plates 32. The stepped surface of the upper joint groove 321 is buckled on the stepped surface of the lower joint groove 311. The stepped surface of the upper joint groove 321 is protruding to set a T-shaped limit block 322. The stepped surface of the lower joint groove 311 is provided with a T-shaped slot 312. Through the cooperation of the T-shaped limit block 322 and the T-shaped slot 312, the upper stepped surface and the lower stepped surface are fitted and slid, so that the two movable plates 32 can extend or retract to both sides of the main board 31, and the width of the bottom plate is changed. The two support seats 1 are respectively installed on the two movable plates 32, and the distance between the two support seats 1 changes with the telescopic movement of the movable plates 32.

[0049] As the distance between the two support seats 1 changes, the length of the support rod 21 installed between the two support seats 1 needs to be telescoped and changed synchronously. Therefore, the support seat 1 is composed of a main rod body 211 and two telescopic rod bodies 212. Telescopic cavities 213 are opened at both ends of the main rod body 211. The two telescopic rod bodies 212 are respectively slidably arranged in the two telescopic cavities 213. When the two movable plates 32 of the base 3 are pulled apart to both sides relative to the main board 31, the two telescopic rod bodies 212 extend from the telescopic cavities 213 at both ends of the main rod body 211 and change their length synchronously with the bottom plate.

[0050] The various technical features in the above implementation modes can be combined arbitrarily as long as there is no conflict or contradiction between the combinations of features. However, due to space limitations, they are not described one by one.

[0051] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
