Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a human body-simulating spine mechanism. Background Art

[0002] In the field of modern medical rehabilitation, the treatment and rehabilitation of spinal disorders are receiving increasing attention. As the axial skeleton of the human body, the spine not only supports the body's weight but also protects the spinal cord, maintains posture, and enables various motor functions. However, spinal injuries, degenerative diseases, and long-term poor posture can all lead to spinal dysfunction, impacting patients' quality of life. Therefore, effective spinal rehabilitation training is crucial for restoring spinal function, alleviating pain, and improving patients' ability to care for themselves.

[0003] Currently, spinal rehabilitation devices on the market primarily focus on providing single or limited directional motion assistance, allowing patients to perform only basic exercises like bending, leaning back, or tilting sideways. These devices are typically worn via shoulder or waist straps. Mechanical structures such as electric actuators restrict range of motion to prevent secondary injuries from excessive stretching or compression. However, these devices lack sufficient motion simulation and biomechanical compatibility. In particular, most devices lack a realistic simulation of the physiological characteristics of the human spine, failing to provide support and guidance for the patient's spine, thus compromising rehabilitation effectiveness.

[0032] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a human-like spine mechanism.

[0033] A human-like spinal structure includes a lower vertebral body 1, a middle vertebral body 2, and an upper vertebral body 3. The lower vertebral body 1 includes a first base body 101, a first elastic member 102 is provided on the top of the first base body 101, a first connecting plate 103 is provided on the rear side of the first base body 101, and a first ball-pair connecting member 104 is provided on the top of the first connecting plate 103. The middle vertebral body 2 includes a second base body 201, a second elastic member 202 is provided on the top of the second base body 201, and a second connecting plate 204 is provided on the rear side of the second base body 201. 03, a second ball-joint connector 204 is provided at the top of the second connecting plate 203, the top of the first elastic member 102 is connected to the bottom of the second seat body 201, the first ball-joint connector 104 is connected to the bottom of the second connecting plate 203, the upper vertebral body 3 includes a third seat body 301, a third connecting plate 302 is provided on the rear side of the third seat body 301, the top of the second elastic member 202 is connected to the third seat body 301, and the second ball-joint connector 204 is connected to the third connecting plate 302.

[0034] The present invention can simulate the structure of multiple vertebrae of the human spine by setting up three parts, namely the lower vertebral body 1, the middle vertebral body 2 and the upper vertebral body 3. The first elastic member 102 and the second elastic member 202 serve as the supporting structure of the first part, and the first ball-pair connecting member 104 and the second ball-pair connecting member 204 serve as the supporting structure of the second part. The two-part structure can support the patient's spine at the same time, and at the same time, a certain rebound effect can be achieved through the action of the first elastic member 102 and the second elastic member 202. The present invention has high motion simulation and biomechanical matching, and can provide support and guidance for the patient's spine.

[0035] In the human-like spinal column mechanism described in this embodiment, two or more middle vertebrae 2 are provided, each of which is disposed between the lower vertebrae 1 and the upper vertebrae 3. Every two adjacent second seat bodies 201 are connected by a second elastic member 202, and every two adjacent second connecting plates 203 are connected by a second ball-joint connector 204. The second seat body 201 at the bottom is connected to the top of the first elastic member 102, the second elastic member 202 at the top is connected to the bottom of the third seat body 301, and the second ball-joint connector 204 at the top is connected to the third connecting plate 302. Specifically, by simulating the human spine with multiple middle vertebrae 2, a more uniform supporting and guiding effect can be achieved.

[0036] In the human-like spinal column mechanism described in this embodiment, a first groove 105 is defined at the top of the first base 101, and the bottom of the first elastic member 102 is disposed in the first groove 105. A second groove 205 is defined at the top of the second base 201, and the bottom of the second elastic member 202 is disposed in the second groove 205. Specifically, the first groove 105 and the second groove 205 respectively limit the position of the first elastic member 102 and the second elastic member 202, so that the first elastic member 102 and the second elastic member 202 can be effectively retained in the first groove 105 and the second groove 205 when the middle vertebral body 2 and the upper vertebral body 3 tilt laterally, backward, or forward relative to the lower vertebral body 1.

[0037] In the human-like spinal column mechanism described in this embodiment, an annular baffle 206 is protruding from the top of the second groove 205. A retaining groove 207 is formed between the outer wall of the baffle 206 and the inner wall of the second groove 205. The bottom of the second elastic member 202 is disposed in the retaining groove 207. Specifically, the provision of the retaining groove 207 can better limit the position of the second elastic member 202 and also provide a certain guiding effect when the second elastic member 202 is compressed.

[0038] In the humanoid spine mechanism described in this embodiment, a third groove 208 is defined at the bottom of the second base 201, and the top of the first elastic member 102 is disposed in the third groove 208. A fourth groove 303 is defined at the bottom of the third base 301, and the top of the second elastic member 202 is disposed in the fourth groove 303. Specifically, the third groove 208 and the fourth groove 303 respectively limit the top of the first elastic member 102 and the top of the second elastic member 202. Thus, the bottom and top of the first elastic member 102 are limited, while the bottom and top of the second elastic member 202 are limited. Meanwhile, the middle portions of the first and second elastic members 102 and 202 are not limited. This allows the present invention to support sideways, backward, and forward tilts, and can provide support and guidance for patients in various situations.

[0039] The present embodiment describes a humanoid spine mechanism, wherein the first ball-pair connector 104 includes a first ball-pair seat 106, a first ball-pair rod 107, and a first connecting ball 108. A first accommodating groove 109 is provided on the top of the first connecting plate 103, and the first connecting ball 108 can be rotatably arranged in the first accommodating groove 109. The first ball-pair seat 106 is arranged on the outer periphery of the first accommodating groove 109. One end of the first ball-pair rod 107 is passed through the first ball-pair seat 106 and is connected to the first connecting ball 108. The other end of the first ball-pair rod 107 is connected to the bottom of the second connecting plate 203. Specifically, the first ball pair seat 106 is provided with a first limiting hole 110 to allow the first ball pair rod 107 to extend into the first accommodating groove 109 and connect with the first connecting ball 108. It can be understood that when the spine is tilted and the first ball pair rod 107 abuts against the inner wall of the first limiting hole 110, the maximum inclination angle between the lower vertebral body 1 and the middle vertebral body 2 is reached. The aperture size of the first limiting hole 110 and the depth of the limiting hole will affect the maximum inclination angle between the lower vertebral body 1 and the middle vertebral body 2. Therefore, the maximum inclination angle can be adjusted by controlling the aperture size of the first limiting hole 110 and the depth of the limiting hole.

[0040] The present embodiment describes a humanoid spine mechanism, wherein the second ball-pair connector 204 includes a second ball-pair seat 209, a second ball-pair rod 210, and a second connecting ball 211. A second accommodating groove 212 is provided on the top of the second connecting plate 203, and the second connecting ball 211 can be rotatably arranged in the second accommodating groove 212. The second ball-pair seat 209 is arranged on the outer periphery of the second accommodating groove 212. One end of the second ball-pair rod 210 is passed through the second ball-pair seat 209 and is connected to the second connecting ball 211. The other end of the second ball-pair rod 210 is connected to the bottom of the third connecting plate 302. Specifically, the second ball pair seat 209 is provided with a second limiting hole 213 to allow the second ball pair rod 210 to extend into the second accommodating groove 212 and connect with the second connecting ball 211. It can be understood that when the spine is tilted and the second ball pair rod 210 abuts against the inner wall of the second limiting hole 213, the maximum inclination angle between the middle vertebral body 2 and the upper vertebral body 3 is reached. The aperture size and depth of the second limiting hole 213 will affect the maximum inclination angle between the middle vertebral body 2 and the upper vertebral body 3. Therefore, the maximum inclination angle can be adjusted by controlling the aperture size and depth of the second limiting hole 213. Similarly, when there are multiple middle vertebrae 2, every two adjacent middle vertebrae 2 are also connected by the second ball-joint connector 204. The aperture size and depth of the second limiting hole 213 will also affect the maximum inclination angle between the two adjacent middle vertebrae 2. Therefore, the maximum inclination angle between the two adjacent middle vertebrae 2 can be adjusted by controlling the aperture size and depth of the second limiting hole 213.

[0041] In the human spine-mimicking mechanism described in this embodiment, the bottom of the first base 101 is connected to a first positioning plate 111, and the first positioning plate 111 is provided with a plurality of first positioning holes 112. Specifically, the first positioning holes 112 can be used to connect to an external mechanism.

[0042] In the human spine-mimicking mechanism described in this embodiment, a second positioning plate 304 is provided on the outer side of the third base 301, and a plurality of second positioning holes 305 are provided on the second positioning plate 304. Specifically, the second positioning holes 305 can be used to connect to an external mechanism.

[0043] In the human spine-mimicking mechanism described in this embodiment, the first elastic member 102 , the second elastic member 202 , and the third elastic member are all springs.

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
