Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically relating to a vibration-type spinal traction device. Background Technology

[0002] The spine, as a crucial component of the human axial skeletal system, not only bears the core functions of supporting the trunk and maintaining posture, but is also a key structure for protecting the spinal cord and transmitting biomechanical loads. For common conditions such as intervertebral disc herniation and facet joint dysfunction caused by thoracic and lumbar spine lesions, mechanical traction therapy has become a widely used non-invasive treatment method in clinical practice. Traditional traction devices widen the intervertebral space by applying axial tensile force, reducing intradiscal pressure and thus relieving nerve compression symptoms.

[0003] However, in order to achieve better traction results, existing traction devices often require applying a large traction force to the human body, which can easily cause stress damage to soft tissues such as the erector spinae muscles and anterior longitudinal ligament. Some patients are forced to discontinue treatment due to their low pain tolerance threshold. Utility Model Content

[0004] The present invention aims to provide a vibration-type spinal traction device that avoids the risk of strain caused by excessive traction force.

[0006] The main support structure includes a support frame and an upper support rod;

[0007] A vibration mechanism, fixed to the upper support rod, outputs vibration along the vertical direction of the support frame; and

[0008] A suspension assembly is provided at the output end of the vibration mechanism and is suitable for being worn under the user's armpit. The suspension assembly vibrates up and down in the vertical direction of the support frame along with the vibration mechanism.

[0009] The user's armpit is positioned on the suspension assembly and suspended from the support frame, and the vibration mechanism and the user's weight are used to achieve vibration traction on the user's spine.

[0010] In this embodiment, a vibration mechanism is added to the traction device, which can apply vibration at a certain frequency during traction. Only a low traction force is needed to achieve a good traction effect, effectively avoiding the risk of soft tissue strain caused by excessive traction force in traditional traction therapy.

[0019] A vibration frame, fixedly connected to the free end of the damping spring, the vibration frame being adapted to connect the suspension assembly; and

[0020] A vibration motor is fixedly mounted on the vibration frame;

[0021] When the vibration motor vibrates, the vibration frame vibrates vertically on the upper support rod with the help of the damping spring.

[0022] In one embodiment, the suspension assembly includes:

[0023] The annular hanger is rotatably mounted on the outer ring of the eccentric bearing, and the annular hanger is limited in the horizontal direction by the annular groove, or it is fixed to the bottom of the vibration frame;

[0028] The base is equipped with a vertically positioned limiting sleeve;

[0029] An insertion tube, inserted into the limiting sleeve, has the upper support rod fixed to its top, and multiple adjustment holes are formed along its height direction; and

[0030] A limiting pin is adapted to be fixedly inserted into the limiting sleeve and one of the adjusting holes.

[0031] In this embodiment, the insertion tube and the base are telescopically connected, allowing for flexible adjustment of the support frame height according to actual needs, thus enhancing the product's versatility.

Therefore, they should not be construed as limitations on the present invention.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0053] Spinal traction devices are commonly used medical devices for treating intervertebral disc herniation, scoliosis, and vertebral degenerative diseases. Their basic structure typically includes a traction bed, a power drive unit, and fixation straps. Traditional traction devices primarily use a motor or hydraulic system to drive the traction straps to apply unidirectional tensile force along the spinal axis, increasing the intervertebral space through continuous traction to achieve decompression. However, traditional traction methods rely solely on static traction force. To achieve a good traction effect, a high traction force must be maintained for an extended period, leading to prolonged tensile stress concentration in soft tissues such as the erector spinae muscles and anterior longitudinal ligament, which can easily cause soft tissue strain. To address these technical problems, this application provides a vibration-type spinal traction device. A vibration mechanism is added to the traction device, enabling the application of mechanical vibration at a specific frequency during traction. This significantly reduces the traction force threshold required for effective traction, achieving a good traction effect with low traction force. This eliminates the risk of soft tissue strain due to excessive traction force, improving the safety and comfort of using the traction device.

[0054] Please refer to the attached document as well. Figure 1 To be continued Figure 8 The present invention provides a vibration-type spinal traction device. The vibration-type spinal traction device includes a main support frame 01, a vibration mechanism 02, and a suspension assembly 04. The vibration mechanism 02 outputs vibrations at a specific frequency, and the suspension assembly 04 applies vibrational traction to the user under the action of the vibration mechanism 02. Specifically, the main support frame 01 includes a support frame 012 and an upper support rod 011. The vibration mechanism 02 is fixed to the upper support rod 011 and outputs vibrations along the vertical direction of the support frame 012. The suspension assembly 04 is disposed at the output end of the vibration mechanism 02 and is suitable for being fitted under the user's armpit. The suspension assembly 04 vibrates up and down along the vertical direction of the support frame 012 with the vibration mechanism 02. The user's armpit is appropriately positioned on the suspension assembly 04 and suspended from the support frame 012, achieving vibrational traction of the user's spine through the vibration mechanism 02 and the user's weight.

[0055] In this embodiment, a specific frequency of vibration is applied by the vibration mechanism 02, which can achieve a good traction effect with a small traction force, avoiding the risk of strain caused by excessive traction force, improving the safety of traction, and greatly reducing the discomfort generated during traction, thus improving the comfort of product use.

[0056] In one alternative embodiment, please refer to the appendix as well. Figure 1 To be continued Figure 4The vibration mechanism 02 outputs power through the motor 022, generating vibration at the output end of the motor 022 via an eccentric structure. Specifically, the vibration mechanism 02 includes the motor 022 and the eccentric bearing 021, with the motor 022 fixedly mounted on the upper support rod 011. The inner ring 0212 of the eccentric bearing 021 is coaxially connected to the output shaft of the motor 022, and the outer ring 0211 of the eccentric bearing 021 is used to connect the suspension assembly 04, forming the vibration output end. The outer ring 0211 and the inner ring 0212 of the eccentric bearing 021 constitute an eccentric motion, thereby generating vibration at a specific frequency in the vertical direction. Optionally, an eccentric cam can be used instead of the eccentric bearing 021 to generate eccentric motion at the output end of the motor 022. Specifically, the output shaft of the motor 022 is fixedly connected to the rotation center of the eccentric cam, and the suspension assembly 04 is rotatably connected to the outer edge of the eccentric cam, generating vibration through the eccentric motion of the eccentric cam.

[0057] Specifically, a vertically mounted mounting plate is fixed to the bottom of the upper support rod 011. The mounting plate has mounting holes. The fixed end of the motor 022 is fixed to the mounting plate with bolts, and the output shaft of the motor 022 extends outwards in a horizontal direction. The mounting plate is fixed to the bottom of the upper support rod 011 by a connector. The connector includes a first connecting plate and a second connecting plate integrally formed. The first connecting plate has mounting holes for bolt assembly with the upper support rod 011, and the second connecting plate is fixed to the mounting plate.

[0058] Furthermore, an annular groove 0213 is provided on the cylindrical surface of the outer ring 0211 of the eccentric bearing 021. The annular groove 0213 is suitable for rotational engagement with the hanging assembly 04. The annular groove 0213 can form a horizontal limit on the hanging assembly 04 to prevent the hanging assembly 04 from falling off the eccentric bearing 021 due to vibration.

[0059] Furthermore, the motor 022 and the eccentric bearing 021 constitute a vibration assembly, which is symmetrically arranged on the upper support rod 011. Correspondingly, the hanging assembly 04 is evenly connected to the vibration assembly.

[0060] Furthermore, a protective cover 023 is provided around the vibration component, and openings are provided on both sides of the protective cover 023 for the hanging component 04 to be connected.

[0061] In another alternative embodiment, please refer to the appendix as well. Figure 7 and attached Figure 8The vibration mechanism 02 applies a specific vibration frequency via the vibration motor 024. Specifically, the vibration mechanism 02 includes a damping spring 026, a vibration frame 025, and a vibration motor 024. The damping spring 026 is vertically arranged, with one end fixed to the upper support rod 011. The vibration frame 025 is fixedly connected to the free end of the damping spring 026 and is adapted to connect to the hanging assembly 04. The vibration motor 024 is fixed to the vibration frame 025. When the vibration motor 024 vibrates, the vibration frame 025 vibrates vertically on the upper support rod 011 with the aid of the damping spring 026.

[0062] In one specific embodiment, the hanging assembly 04 includes an annular pendant 041, a hook 042, an annular strap 044, and a sling 043. When vibration is output through the eccentric bearing 021, the annular pendant 041 is rotatably mounted on the outer ring 0211 of the eccentric bearing 021. Furthermore, the annular pendant 041 is hung in an annular groove 0213, which provides a horizontal limit. Under gravity, the annular pendant 041 does not rotate with the eccentric bearing 021, but vibrates vertically with the eccentric bearing 021, thus causing the hanging assembly 04 to vibrate. Alternatively, when vibration is applied through the vibration motor 024, the annular pendant 041 is fixed to the bottom of the vibration frame 025. Based on the above two embodiments, the hook 042 is hung on the annular pendant 041. The annular strap 044 is suitable for securing under the user's armpit. The sling 043 passes through the hook 042 at its middle, and both ends of the sling 043 are fixedly connected to the loop strap 044. Preferably, there are two slings 043, each connected to one side of the loop strap 044. Correspondingly, the vibration output ends of the vibration mechanism 02 are located on both sides and connected to the two slings 043 respectively. The loop strap 044 is provided with buckles for adjusting its tightness.

[0063] In one specific embodiment, the support frame 012 includes a base 0125, an insertion tube 0121, and a limiting pin 0123. The base 0125 is provided with a vertically arranged limiting sleeve 0124. The insertion tube 0121 passes through the limiting sleeve 0124, and a support rod 011 is fixedly mounted on the top of the insertion tube 0121. The insertion tube 0121 has multiple adjustment holes 0122 along the height direction. The limiting pin 0123 is adapted to be fixedly inserted into the limiting sleeve 0124 and one of the adjustment holes 0122. By fixing the limiting sleeve to the adjustment holes 0122 of different heights, the height of the support frame 012 can be adjusted, allowing the user to flexibly adjust the height of the support frame 012 according to actual needs.

[0064] Furthermore, a handrail 03 and a footrest 05 for the user to step on are fixed on the support frame 012. Preferably, there are two footrests 05, each inclined inwards, and upward-extending guardrails 051 are provided on both sides of the footrest 05. The user can stand on the footrest 05 and adjust the straps. After the straps are fixed, the user's feet can leave the footrest 05 to achieve suspension traction. Since the user's feet are spread apart on the footrests 05 when standing, the force exerted by the feet on the footrests 05 can be divided into horizontal and vertical components. The inclined design of the footrest 05 can offset part of the horizontal force, and the guardrails 051 on both sides of the footrest 05 can prevent the user from slipping and falling off the footrest 05.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
