Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of rehabilitation medical devices, and particularly relates to a cervical vertebra rehabilitation traction device. BACKGROUND

[0002] In today's society, with the significant increase in the number of office workers and people who keep their heads down, the number of people with cervical vertebra problems is increasing. In order to improve the cervical vertebra condition of this group of people, or correct, or treat, or rehabilitate, there are many cervical vertebra physiotherapy devices on the market, such as cervical braces and traction devices.

[0003] Cervical brace products are small in structure and light in weight, and do not hinder normal body movement when worn on the human neck. They rely on the support of the pre-neck support to support the chin upwards, and rely on the support of the air bag and other components behind the neck to support the cervical vertebra, keeping the cervical vertebra in a normal physiological curvature or tending to be correct. This type of product is the most common on the market, involving different brands and price ranges. Because of its small structure, it does not hinder the wearer's work, but the supporting force of this type of product is limited and is often used for correction or prevention after mild symptoms.

[0004] Traction products need to be fixed to the wall or support for use, with the patient sitting on the seat below or standing, the cervical vertebra is pulled upwards by the traction belt, which has an external pulling effect and adjustable force, and has better rehabilitation treatment effect on cervical vertebra problems, but the disadvantage is that the patient's body cannot move at will, and even the movement of the neck will cause changes in the pulling force.

[0005] In view of the above status, the present application pursues to design a cervical vertebra traction device that takes into account the advantages of cervical brace and traction products, that is, it can be moved with the patient like a cervical brace product, and does not hinder the daily movements of other parts of the body, and can also provide adjustable upward pulling force to have better rehabilitation effect. In addition, the inventor also hopes that the traction force on the cervical vertebra can be adjusted to a relatively stable state, so that the traction force will not change suddenly when the patient moves within a certain range, avoiding secondary damage to patients with severe cervical vertebra problems during the rehabilitation process. SUMMARY

[0006] Based on the above considerations, the purpose of the present application is to provide a cervical vertebra rehabilitation traction device that provides a stable upward pulling force to the patient by being worn on the patient's neck, assisting in the rehabilitation and treatment of the cervical vertebra, and the wearing method does not hinder the patient's daily movements such as walking.

[0007] The technical scheme adopted by the present application is as follows: A cervical vertebra rehabilitation traction device is provided, which is a wearable structure. The friction force of a thick covering element covering the shoulder and the front chest or the back provides a constraint force for a support assembly located above the shoulder. Specifically, a shoulder and back fixing belt is used, which is arranged on the shoulder and the back. The support assembly is fixed and supported on the upper part of the shoulder and back fixing belt. A cervical vertebra traction belt is fixed and installed on the support assembly in a hanging manner. The support assembly is composed of two side support rods distributed on the two shoulders and a transverse connecting arm transversely connected to the upper end portions of the two side support rods. The two sides of the cervical vertebra traction belt are fixed to the two sides of the upper end of the support assembly through traction force applying assemblies and connecting pieces. The traction force applying assemblies are responsible for providing a stable upward traction force for the cervical vertebra traction belt.

[0008] The traction force applying assembly comprises a fixed shaft fixedly installed on the upper end of the support assembly. A threaded cylinder capable of spirally moving along the fixed shaft is sleeved on the fixed shaft. A spiral manganese steel belt made of pre-stress is spirally wound on the threaded cylinder. The initial state of the manganese steel belt is a spiral structure. One end portion of the manganese steel belt extends out of the spiral segment to form a straight segment. The lowermost end of the straight segment is connected to the connecting piece or directly connected to the upper end of one side of the cervical vertebra traction belt. The other end portion of the spiral segment is provided with a rivet. When the manganese steel belt is wound on the threaded cylinder, the end portion is fixed to the threaded cylinder through the rivet. When the manganese steel belt is stretched downward, the manganese steel belt drives the threaded cylinder to rotate so as to release a longer portion from the spiral segment and become a straight segment to adapt to the height position of the cervical vertebra traction belt. The threaded cylinder spirally moves along the axis of the fixed shaft when rotating, so that the position of the manganese steel belt extending out of the threaded cylinder is always unchanged relative to the position of the fixed shaft and the support assembly. The manganese steel belt is composed of a plurality of thin manganese steel sheets, for example, 3-10 sheets.

[0009] Spiral protrusions are arranged on the outer surface and the inner surface of the threaded cylinder, which are outer thread protrusions and inner thread protrusions, respectively. The outer thread protrusions are matched with the shape of the spiral manganese steel belt, so that the manganese steel belt is wound and installed along the outer thread protrusions. The inner thread protrusions are matched and installed with the thread grooves arranged on the surface of the fixed shaft, which limits the threaded cylinder to only rotate and axially move along the fixed shaft. Specifically, the fixed shaft can be fixedly installed on the support assembly in an inclined manner relative to the horizontal plane. The inclination angle is the same as the angle of the spiral inclination angle of the manganese steel belt. If the fixed shaft is in a horizontal state, the straight segment of the manganese steel belt will necessarily extend out of the threaded cylinder in an inclined manner, which is not convenient for providing a traction force to the cervical vertebra traction belt located below. If the fixed shaft is arranged in an inclined manner, the straight segment of the manganese steel belt can extend out of the threaded cylinder in a vertical downward manner, which is convenient for the installation of the cervical vertebra traction belt and the transmission of the traction force.

[0010] In use, the cervical traction belt is sleeved at the neck, and obviously different individual differences will make the force of the cervical traction belt different, so the initial height of the cervical traction belt can be set relatively high, and when the cervical traction belt needs to be specifically sleeved at the neck, the cervical traction belt is pulled downward, the threaded cylinder rotates around the fixed shaft and moves axially, the manganese steel belt extends downward from the threaded cylinder by an appropriate length to adapt to the traction height of the cervical traction belt, and when the user slightly raises or lowers the chin, the manganese steel belt retracts or extends by a corresponding length, so that the traction height of the cervical traction belt is automatically adapted, and a stable traction force is always provided.

[0011] The advantages of the technical scheme of the present application are that:

[0012] 1. The traction height of different individuals can be adapted under the premise of ensuring a stable traction force, that is, the same traction force is provided for different patients, and there is no difference in effect.

[0013] 2. During traction, the slight head-raising and head-lowering actions of the patient do not affect the traction effect, and the manganese steel belt automatically extends or retracts to adapt to the change in traction height caused by the head-raising and head-lowering actions while maintaining a stable traction force.

[0014] 3. The overall structure is a shoulder and neck wearing structure, which provides a large traction force and does not hinder the wearer from walking and moving, and the effect is similar to that of a seat fixed traction product, and the convenience is similar to that of a cervical collar product, which takes the advantages of the two types of products.

[0033] In the overall collocation relationship of the structure, see Figure 2 , Figure 2 is the assembly split state schematic diagram of the cervical vertebra rehabilitation traction device of the present application, the whole is shown from the perspective opposite to Figure 1 Each connecting piece 5 is connected with the lower end of the traction force applying assembly 4 distributed on both sides of the support assembly 1, the lower end of the connecting piece 5 is fixed on the upper end of the cervical vertebra traction belt 3, the lower end of the cervical vertebra traction belt 3 is constrained to be sleeved on the neck, and the shoulder and back fixing belt 2 is relatively thick and is lapped on the human shoulder, so that the support assembly 1 can be stably supported on the human shoulder, and the support plate is fixed on the position of the shoulder and back fixing belt 2 above the shoulder, and the lower end of the support assembly 1 is fixedly abutted with the support plate through the mounting plate on both sides.

[0034] See Figure 3, is the support assembly structure schematic view of the cervical vertebra rehabilitation tractor of the present application, the support assembly is composed of two side support rods 1-1 supported on both sides of the shoulder and the transverse connecting arm 1-2 transversely connected on the upper end of the two side support rods 1-1, the support assembly 1 can be the two side support rods 1-1 and the transverse connecting arm 1-2 of the integral bending structure, for the convenience of description, it is divided into three parts, alternatively, the two ends of the transverse connecting arm 1-2 are fixedly connected with one side support rod 1-1 respectively, namely the support assembly 1 is the split structure, of course, it is not limited to the "[ " type shown in the drawing, and can be arc-shaped or straight rod type, etc. On the upper end of the support assembly 1, the end of the side support rod 1-1 or the end of the transverse connecting arm 1-2 is formed with the mounting portion 1-4, the bolt hole is formed on the mounting portion 1-4, for fixing and mounting the traction force assembly 4; the lower end of the side support rod 1-1 is integrally formed with the mounting plate 1-3, and the mounting plate 1-3 is used for bolt fixing with the shoulder back fixing belt 2. The side support rod 1-1 and the transverse connecting arm 1-2 are both light rigid rods, such as adopting nylon material, hard plastic or aluminum alloy and other conventional materials with small density and sufficient rigidity, so as to reduce the total weight of the whole structure and reduce the burden of the human body shoulder.

[0035] Figure 4 , is the traction force assembly structure schematic view of the cervical vertebra rehabilitation tractor of the present application, Figure 5Fig. 1 is a schematic view of the traction force exerting assembly of the cervical vertebra rehabilitation traction device in a disassembled state, the core component of the traction force exerting assembly is a threaded cylinder 4-4 mounted on a fixed shaft 4-3 and a manganese steel band 4-5 wound around the threaded cylinder 4-4, the manganese steel band 4-5 is composed of multiple thin steel bands, the structure of multiple thin manganese steel bands is adopted to provide stable and constant pulling force for the cervical vertebra traction device, conventional tension springs and inelastic ropes are obviously not suitable, either the pulling force will change with the change of the height of the traction position, or the height of the traction cannot be changed, the adaptability is poor, and the traction process is only a process of orthopedic treatment without traction force. The inventor finds a means to provide stable pulling force in other fields, that is, the thin steel band of manganese steel is made into a spiral structure by pre-stress, which not only has the spring performance of elastic stretching and restoring to the initial spiral structure, but also the pulling section of the spiral thin steel band changes from the spiral bending state to the straight state, which is a process of absorbing work, that is, the state change process of pulling and deformation needs to exert force when the spiral structure of the thin steel band changes from the initial state to the intermediate state of the longer straight section, after being stabilized in the intermediate state, no additional force is needed, but the thin steel band has a tendency to restore to the initial state, which provides upward pulling force and enables the spiral structure of the manganese steel thin steel band to provide stable pulling force, multiple thin manganese steel bands are used together, on the one hand, the single thin manganese steel band is not easy to cut the skin, but the single thick manganese steel band has too much deformation force from the spiral bending to the straight state, so the thickness of the single thin manganese steel band is reduced, for example, the thickness of each thin manganese steel band is between 0.2-1.0 mm, on the other hand, multiple thin manganese steel bands can provide greater traction force, that is, the combined force of multiple thin manganese steel bands, therefore, 3-10 thin manganese steel bands can be set according to the actual pulling force requirement, in the illustrated embodiment, an embodiment of four thin manganese steel bands is shown.

[0036] Figure 7 Fig. 2 is a schematic view of the traction force assembly in the traction force exerting assembly of the cervical vertebra rehabilitation traction device in a disassembled state, Figure 8 Fig. 3 is a schematic view of the cross-sectional state of the traction force assembly in the traction force exerting assembly of the cervical vertebra rehabilitation traction device, as shown in the figure, the outer surface of the threaded cylinder 4-4 is formed with an external thread protrusion 4-4-1, the external thread protrusion 4-4-1 forms a spiral mounting groove on the outer surface of the threaded cylinder 4-4, which is suitable for the width of the manganese steel band 4-5, so that the manganese steel band 4-5 is spirally wound on the threaded cylinder 4-4, one end of the manganese steel band 4-5 is fixed by a rivet 4-5-1 and limited on the threaded cylinder 4-4, the other end is connected to the connecting piece 5, specifically, the other end of the manganese steel band 4-5 is provided with an oblong or strip-shaped connecting hole 4-5-2, a screw mounted at the end of the connecting piece 5 penetrates through the connecting hole 4-5-2 to connect the two together. Referring to Figure 8On the inner surface of the threaded cylinder 4-4, there is also an internal thread protrusion 4-4-2 protruding towards the inside, which is used to screw the threaded cylinder 4-4 onto the fixed shaft 4-3 in a screwing fit.

[0037] The traction force applying assembly also comprises a first fixing member 4-1 and a second fixing member 4-2, which are both bolted and mounted on the mounting portion 1-4 of the side portion of the support assembly 1, and which respectively fix one end portion of the fixed shaft 4-3 by means of a bolt or a pin shaft or the like structure, so as to mount the fixed shaft 4-3 on the support assembly 1, as shown in Figure 6 The fixed shaft 4-3 is provided with through holes at both end portions thereof in the embodiment shown in the figure, so as to be fixed and mounted on the first fixing member 4-1 and the second fixing member 4-2 by means of a bolt or a pin shaft, of course, it can also be assembled by means of a key groove assembly, an insertion assembly or the like, or by means of a way that both ends thereof are respectively fused to the first fixing member 4-1 and the second fixing member 4-2, so as to be locked and assembled on the support assembly 1 in a rotatable manner, and the surface of the fixed shaft 4-3 is provided with a thread groove 4-3-1, which is spirally wound along the surface of the fixed shaft 4-3, so that when the threaded cylinder 4-4 is sleeved on the fixed shaft 4-3, the threaded cylinder 4-4 moves along the thread groove 4-3-1 in a spiral manner. In combination with Figure 6 and Figure 8 The pitch and the spiral angle of the thread groove 4-3-1 are the same as the pitch and the spiral angle of the internal thread protrusion 4-4-2 of the inner surface of the threaded cylinder 4-4, that is, the threaded cylinder 4-4 is screwed and sleeved on the fixed shaft 4-3, wherein the internal thread protrusion 4-4-2 is embedded in the thread groove 4-3-1, and under the cooperation of the two, the threaded cylinder 4-4 can only move along the fixed shaft 4-3 in an axial direction in a rotatable manner, and the reason for such arrangement is to keep the position of the manganese steel belt 4-5 extending out of the threaded cylinder 4-4 unchanged relative to the fixed shaft 4-3, the position and the angle of the fixed shaft 4-3 relative to the support assembly 1 are unchanged, and the position of the part of the manganese steel belt 4-5 extending out of the threaded cylinder 4-4 relative to the fixed shaft 4-3 is also unchanged, so that the position of the part relative to the support assembly 1 is unchanged, and the cervical vertebra traction belt 3 connected below can only move up and down relative to the support assembly 1 due to the upward retraction or the downward extension of the manganese steel belt 4-5, and will not shake in a front-back direction.

[0038] Figure 9 is a schematic view of the mounting state of the connecting member of the cervical vertebra rehabilitation traction device, Figure 10 is Figure 9 is a schematic view of the longitudinal section structure at position A in Figure 9The middle fixed shaft 4-3 is at an inclined angle, which can be defined by the height of the installation position of the first fixing member 4-1 and the second fixing member 4-2 to the inclination of the fixed shaft 4-3, and after the manganese steel belt 4-5 is spirally wound along the external thread convex 4-4-1 to extend downwardly from the thread cylinder 4-4, the manganese steel belt 4-5 has an inclination of the spiral inclination angle relative to the fixed shaft 4-3, and the installation position of the fixed shaft 4-3 is set to the same inclined angle as the spiral inclination angle of the external thread convex 4-4-1, so that the manganese steel belt 4-5 is at a vertically downward direction when extending from the thread cylinder 4-4, and the verticality of the pulling force provided by the manganese steel belt 4-5 and the correctness of the connected cervical vertebra traction belt 3 below can be maintained. The manganese steel belt 4-5 is composed of multiple thin steel belts, but it always has a certain thickness, and when it is bent, the multiple thin steel belts naturally form a length difference that is sequentially exceeded at the end of the connection with the connecting member 5 due to the different bending radii. Therefore, the joint 5-1 of the connecting member 5 allows the length difference of the end of the manganese steel belt 4-5 to be accommodated, which is reflected in Figure 10 The end of the manganese steel belt 4-5 is connected to the joint 5-1 of the connecting member 5 by a screw, and the connecting hole 4-5-2 of the end of the manganese steel belt 4-5 is used for the screw to pass through. The strip-shaped connecting hole 4-5-2 allows the screw to slide up and down in it, so that when the manganese steel belt 4-5 extends or retracts relative to the thread cylinder 4-4, the length difference of the extension of the thin steel belts inside and outside is balanced by the screw sliding in the strip-shaped hole 4-5-2.

[0039] Referring to Figure 1 In use, the cervical vertebra traction belt 3 is wrapped around the neck, and it is obvious that individual differences will cause the pulling height of the cervical vertebra traction belt 3 to be different, so the initial height of the cervical vertebra traction belt 3 can be set relatively high. When it is necessary to be specifically wrapped around the neck, the cervical vertebra traction belt 3 is pulled downward, the thread cylinder 4-4 rotates around the fixed shaft 4-3 and moves axially, and the manganese steel belt 4-5 extends downwardly from the thread cylinder 4-4 by an appropriate length to adapt to the traction height of the cervical vertebra traction belt 3. When the user slightly raises or lowers the chin, the manganese steel belt 4-5 retracts or extends by a corresponding length to automatically adapt the traction height of the cervical vertebra traction belt 3, and always provides a stable traction force.

[0040] Although the specific embodiments of the present application have been described above with reference to the drawings, they are not a limitation on the scope of protection of the present application. Those skilled in the art should understand that various equivalent structures or equivalent processes can be made on the basis of the technical solutions of the present application without creative labor, or directly or indirectly applied to other related technical fields, which are still within the scope of protection of the present application.
