Description

Technical Field

[0001] The application relates to physiotherapy devices, and more particularly to a cervical spine fixation device, wherein the width of the jaw is adjustable. Background Technology

[0002] Currently, the most common physiotherapy device for cervical spine care is the cervical traction device. These products typically focus on improving the traction effect, often neglecting the user experience, particularly the sensation in the user's jaw and neck. Because neck length and thickness vary from person to person, a single model cannot fit all necks. This means manufacturers need to prepare multiple models to accommodate different users. The standard for determining the model is simply choosing an average standard from a selected group of people. In other words, a particular model may only be suitable for a certain group, but not necessarily for a specific user, and it cannot be adjusted for jaw and / or neck width. This means that the same model may fit some people well while not fitting others, affecting the effectiveness of the treatment. However, there is no product on the market that can adjust for the overall thickness and length of the neck. For manufacturers, reducing the number of models would reduce costs.

For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0062] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0063] like Figures 1-5 As shown, the cervical spine fixation device of the present invention includes an adjustment platform 20, which further has a wearing cavity 24. The wearing cavity 24 allows a user to wear the adjustment platform 20 around the user's neck. The wearing cavity 24 further defines a wearing opening 241 through which the user wears the adjustment platform 20. When the user wears the adjustment platform 20 around their neck, the adjustment platform 20 is adjustable to fit the user's neck. Specifically, the adjustment platform 20 adjusts the width of the wearing cavity 24 to fit the width of the user's neck, thereby fixing the user's neck. The cervical spine fixation device of the present invention further includes a posterior neck support 10, which is detachably connected to the adjustment platform 20. After the user wears the adjustment platform 20 around their neck, the posterior neck support 10 is fitted against the back of the user's neck, and then the posterior neck support 10 is fixed to the adjustment platform 20. In other words, the posterior neck support 10 conforms to the back of the user's neck to provide support and further stabilize the user's neck. After the posterior neck support 10 is fixed to the user's neck, the adjustment platform 20 and the posterior neck support 10 secure the user's neck. In a preferred embodiment of the present invention, two adjustment straps 21 detachably connect the two sides of the posterior neck support 10 to the two sides of the adjustment platform 20, respectively.

[0064] The user's neck has a certain length. Therefore, in this application, the width of the user's neck is adjusted by adjusting the upper and lower parts of the neck separately. In a preferred embodiment of this application, the upper part of the user's neck is adjusted by adjusting the width of the user's upper jaw. The top of the adjustment platform 20 provides adjustment of the upper part of the user's neck by adjusting the width of the user's lower jaw. The bottom of the adjustment platform 20 provides adjustment of the width of the lower part of the user's neck. By adjusting the width of the upper and lower parts of the user's neck separately, the overall width of the user's neck is adjusted. Furthermore, the adjustment platform 20 adjusts the upper and lower parts of the user's neck separately to accommodate more types of the user's neck. For example, in some special cases, the upper part of the user's neck is wider than the lower part of the user's neck, or the lower part of the user's neck is wider than the upper part of the user's neck. That is, the adjustment platform 20 of a preferred embodiment of this application can be adapted to situations where the width of the upper part of the user's neck is inconsistent with the width of the lower part of the user's neck. Furthermore, when the top of the adjustment platform 20 is adjusted to reduce its width, the bottom of the adjustment platform 20 is also adjusted to reduce its width.

[0065] The adjustment platform 20 further provides adjustment of the jaw angle. After adjusting the user's jaw angle, the adjustment platform 20 further provides vertical adjustment to position the user's neck in a suitable position. The adjustment platform 20 provides fixation and traction for the user's neck in this suitable position. In a preferred embodiment of the invention, the suitable position is a slight upward tilt of the user's jaw. The adjustment platform 20 adjusts the upward tilt angle of the user's jaw to achieve a suitable position. Then, the adjustment platform 20 adjusts the vertical position to support the user's neck and provide traction in a suitable position. It is worth mentioning that most users work with their heads down; therefore, a slight upward tilt of the jaw facilitates cervical spine extension and restores the natural arch. Then, the adjustment platform 20 adjusts the vertical direction to fix the user in an extended posture, thereby supporting the user's neck. This further achieves the effect of traction for the user's neck. It is worth mentioning that, in order for the adjustment platform 20 to support the user's neck in a suitable position during vertical adjustment, [further details are needed]. The adjustment platform 20 provides a cushioning structure so that the adjustment platform 20 can be adjusted to a suitable position to support the user's neck, and the user feels comfortable during the adjustment process.

[0066] The adjustment platform 20 further includes an adjustable base 21, two adjustment devices 22, and a jaw support device 23. The two adjustment devices 22 are respectively mounted on both sides of the adjustable base 21. The jaw support device 23 is adjustablely connected to both adjustment devices 22. Specifically, the bottoms of the two adjustment devices 22 are respectively mounted on both sides of the adjustable base 21. The tops of the two adjustment devices 22 are respectively connected to both sides of the jaw support device 23. The middle portion of the adjustable base 21 defines the wearing cavity 24. The jaw support device 23 is disposed on the top of the adjustment platform 20. The adjustable base 21 is disposed on the bottom of the adjustment platform 20. The jaw support device 23 provides horizontal adjustment to accommodate the width of the user's jaw. The adjustable base 21 provides horizontal adjustment to accommodate the width of the lower part of the user's neck. When the jaw support device 23 is adjusted to reduce its width, the adjustable base 21 moves towards the user's neck as the jaw support device 23 moves, thereby reducing the width of the adjustable base 21. Specifically, when the jaw support device 23 is adjusted to reduce its width, it moves closer to the user's neck, causing the two adjustment devices 22 to move closer to the user's neck, thus bringing the adjustable base 21 closer to the user's neck and reducing its width.

[0067] In a preferred embodiment of the present invention, after the adjustment platform 20 is worn around the user's neck, the adjustable base 21 extends from the user's shoulder to the user's chest. Preferably, the adjustable base 21 extends towards the user's back. The adjustable base 21 can conform to the user's back. The tops of the two adjustment devices 22 are respectively adjustablely connected to both sides of the jaw support device 23. Preferably, the ends of the jaw support device 23 are respectively adjustablely mounted on the tops of the two adjustment devices 22. The angle of the jaw support device 23 is adjusted by the two adjustment devices 22 to allow the user to adjust the slight upward tilt of the jaw to achieve a comfortable cervical spine posture. Preferably, the jaw support device 23 adjusts the angle of supporting the user's jaw by rotation. After the user's jaw is in a comfortable posture, the two adjustment devices 22 lock the jaw support device 23 to restrict the rotation of the jaw support device 23. It is worth mentioning that when the two adjustment devices 22 continue to be adjusted vertically, the two sides of the adjustable base 21 move slightly away from the user's neck to form a buffer space 25 between the user's neck and the adjustment device 23. This buffer space 25 facilitates the adjustment device 23 in adjusting the jaw support device 23 to a suitable position, and also ensures user comfort during the adjustment process. Existing cervical traction devices lack this buffer space, resulting in the user's neck not being adjusted to a suitable position, but only to a sub-suitable position. The reason existing cervical traction devices can only be adjusted to a sub-suitable position is that they fit tightly against the user's neck, lacking a buffer space. This causes the two adjustment devices 23 to fit tightly against the user's neck skin during the adjustment from the sub-suitable position to the suitable position. This tight contact with the user's skin increases resistance for the adjustment device 23 and also causes strong discomfort, even pain, in the user's neck. Therefore, existing cervical traction devices are only adjusted to a slightly suitable position before adjustment stops. Using existing cervical traction devices at this slightly suitable position reduces their effectiveness and fails to achieve the desired results. The cervical fixation device of this invention incorporates a buffer space 25 to reduce friction between the two adjustment devices 23 and the user's neck skin, thereby facilitating adjustment from the slightly suitable position to the suitable position and improving the user experience. The user feels comfortable during adjustment. Preferably, after adjustment to the suitable position, the two sides of the adjustable base 21 move closer to the user's neck to conform to the user's neck.

[0068] The adjustable base 21 further includes two shoulder supports 211 and an adjustment portion 212. The adjustment portion 212 is connected to the two ends of the two shoulder supports 211 respectively. The wearing cavity 24 is defined between the two shoulder supports 211. The angle between the two shoulder supports 211 can be rotatably adjusted via the adjustment portion 212. The adjustment portion 212 further includes a pivot 2121 and a sleeve 2122. The sleeve 2122 is fitted onto the pivot 2121 to allow the sleeve 2122 to rotate around the pivot 2121. The pivot 2121 is located at one end of one of the shoulder supports 211. The sleeve 2122 is located at one end of the other shoulder support 211. Specifically, the pivot 2121 is located at the middle of one pivot end 2111 of one of the shoulder supports 211. Preferably, the diameter of the pivot 2121 is less than the width of the pivot end 2111. The sleeve 2122 is disposed at the middle of the sleeve end 2112 of another shoulder support 211. Preferably, the diameter of the sleeve end 2112 is less than the middle of the sleeve end 2112. The adjusting part 212 further includes an angle limiting mechanism 2123. The angle limiting mechanism 2123 is disposed on the pivot 2121 and the sleeve 2122 respectively. Specifically, the angle limiting mechanism 2123 further includes a first limiting member 21231 and a second limiting member 21232. The first limiting member 21231 is disposed on the bottom outer side of the pivot 2121. The second limiting member 21232 is disposed on the bottom outer side of the sleeve 2122. When the sleeve 2122 is fitted onto the rotating shaft 2121, the first limiting member 21231 and the second limiting member 21232 are on the same plane, and there is a gap between the first limiting member 21231 and the second limiting member 21232. The rotation range of the sleeve 2122 is limited by the range of the gap between the first limiting member 21231 and the second limiting member 21232. When another shoulder support member 211 approaches one of the shoulder support members 221, the sleeve 2122 rotates around the rotating shaft 2121 so that the first limiting member 21231 contacts the second limiting member 21232, thereby restricting the rotation of the other shoulder support member 211.

[0069] As shown in Figure 3, the shoulder support 211 has a curved shape. Specifically, the shoulder support 211 extends downwards to conform to the user's shoulder and chest. Furthermore, the shoulder support 211 extends from the user's shoulder towards the user's chest. Preferably, when the shoulder support 211 extends to the user's chest, it converges towards the center of the user's chest, so that the two shoulder supports 211 are connected at the center of the chest. In a preferred embodiment of the invention, the adjustment part 212 is located at the center of the user's chest. The pivot end 2121 of one shoulder support 211 and the sleeve end 2112 of the other shoulder support 211 are connected to the center of the user's chest. Preferably, the adjustable base is U-shaped.

[0070] The shoulder support 211 further includes a mounting bracket 2113. The mounting bracket 2113 can be fixed to an arc surface to form a mounting portion 21131 on the arc surface for mounting the adjustment device 22. Preferably, the bottom of the adjustment device 22 can be embedded in the mounting portion 21131. The mounting portion 21131 further includes a guide wall 21132. The guide wall 21132 guides the adjustment device 22 to be vertically mounted on the mounting bracket 2113. The guide wall 21132 is located on one side near the adjustment portion 212. Furthermore, the guide wall 21132 maintains the verticality of the adjustment device 22. Further, through the mounting bracket 2113, the pressure on the adjustment device 22 from the head is guided to the user's shoulders and chest, thereby reducing the pressure on the user's shoulders. In other words, the mounting bracket 2113 has a force-distributing effect, thereby improving the comfort of using the cervical spine fixation device of the present invention.

[0071] The adjusting device 22 further includes a distance adjusting device 221 and an angle adjusting device 222, the angle adjusting device 222 being disposed on one side of the distance adjusting device 221. The bottom of the distance adjusting device 221 is mounted to the mounting portion 21131 to adjustably fix the distance adjusting device 221. The angle adjusting device 222 is adjustablely connected to the jaw support device 23 to adjust the angle of the jaw support device 23. The distance adjusting device 221 further includes a knob 2211, an adjusting rack 2212, an adjusting bracket 2213, and an adjusting device housing 2214. The knob 2211 and the adjusting rack 2212 are mounted on the adjusting bracket 2213. The adjusting knob 2211 adjusts the vertical movement of the adjusting rack 2212 within the bracket 2213. The adjusting rack 2212 further includes a set of teeth 22121, which is disposed on one side of the adjusting rack 2212. The adjusting rack 2212 further includes a limiting strip 22122. The limiting strip 22122 is located in the middle of the adjusting rack 2212. Preferably, the limiting strip 22122 is located at the rear of the set of teeth 22121. The limiting strip 22122 limits the vertical movement of the adjusting rack 2212. Preferably, the adjusting rack 2212 further has a limiting groove 22123. The limiting groove 22123 matches the adjusting bracket 2213 to limit the vertical movement of the adjusting rack 2212 within the adjusting bracket 2213.

[0072] The adjusting bracket 2213 further includes at least one directional limiting groove 22131, which corresponds to the limiting strip 22122. That is, the limiting strip 22122 is embedded in the directional limiting groove 22131, allowing the limiting strip 22122 to move vertically along the directional limiting groove. Preferably, the directional limiting groove 22131 is located on the inner side of the adjusting bracket 2213. The adjusting bracket 2213 further includes a limiting member 22132, which is disposed inside the adjusting bracket 2213. The limiting member 22132 passes through the limiting groove 22123 to limit the adjustment range of the adjusting rack 2212. The adjusting bracket 2213 further has a mounting cavity 22133. The mounting cavity 22133 is disposed at the top of the adjusting bracket 2213 for mounting the adjusting knob 2211.

[0073] The knob 2211 further includes an operating part 22111. The operating part 22111 facilitates operation of the knob 2211 by the user. The knob 2211 further includes a rotating shaft 22112 and an adjusting gear 22113. The adjusting gear 22113 meshes with a set of teeth 22121 of the adjusting rack 2212. By rotating, different teeth 22121 are engaged, causing the adjusting rack 2212 to move vertically. The gear 22113 is located at the end of the rotating shaft 22112. The rotating shaft 22112 is connected to the operating part 22111. The rotating shaft 22112 is rotated through the operating part 22111. In a preferred embodiment of the present invention, the adjusting gear 22113 further includes two strip teeth 22114, and the two strip teeth 22114 are located on the edge of the adjusting gear 22113. Two strip-shaped teeth 22114 are arranged opposite to each other so that both strip-shaped teeth 22114 can simultaneously engage with the adjusting rack 2212. Preferably, the strip-shaped teeth 22114 are arranged axially. The adjusting bracket 2213 further includes at least one limiting shaft 22134. The limiting shaft 22134 is disposed at the bottom of the adjusting bracket 2213. The mounting portion 21131 of the mounting bracket 2113 is further provided with a mounting groove 21133. The mounting groove 21133 is used to mount the limiting shaft 22134. When the adjusting bracket 2213 is subjected to pressure from the neck, the adjusting bracket 2213 rotates slightly to buffer the pressure on the adjusting bracket 2213. The limiting shaft 22134 is disposed in the middle of the adjusting bracket 2213. The mounting groove 21133 is disposed in the middle of the mounting portion 21131. The mounting groove 21133 is recessed in the middle of the mounting portion 21131 to form the mounting groove 21133. Simultaneously, two mounting surfaces 21134 are formed on both sides of the mounting groove 21133. The two mounting surfaces 21134 correspond to the two sides of the bottom surface of the limiting shaft 22134 of the adjusting bracket 2213. Preferably, the limiting shaft 22134 is slightly higher than the mounting groove 2113 to form a buffer between the bottom of the adjusting bracket 2213 and the bottom of the mounting portion 21131. Slight rotation of the adjusting bracket 2213 relieves the pressure on the adjusting bracket 2213.

[0074] The adjusting device housing 2214 has an adjusting bracket receiving cavity 22141. The adjusting bracket receiving cavity 22141 accommodates the adjusting bracket 2213. The adjusting device housing 2214 further has an adjusting knob channel 22142. The knob 2211 extends beyond the adjusting device housing 2214 through the adjusting knob channel 22142. The user operates the adjusting knob 2211 to move the adjusting rack 2212 in the vertical direction, causing the adjusting device housing 2214 to move with the vertical movement of the adjusting rack 2212. During the movement of the adjusting device housing 2214, the knob 2211 remains in the adjusting knob channel 22142. The adjusting device housing 2214 further includes an adjusting bracket connecting portion 22143. The adjusting bracket connecting portion 22143 is disposed on the inner top side of the adjusting device housing 2214. The adjusting bracket connecting portion 22143 is connected to the adjusting bracket 2213. When the adjusting bracket 2213 moves upward in the vertical direction, the adjusting bracket 2213 supports the adjusting device housing 2214 to move upward in the vertical direction. When the adjusting bracket 2213 moves downward in the vertical direction, the adjusting device housing 2214 moves downward in the vertical direction.

[0075] like Figure 5As shown, the angle adjustment device 222 is disposed on one side of the distance adjustment device 221. Preferably, the angle adjustment device 222 further includes a fixing part 2221, a rotating part 2222, and an angle limiting part 2223. The fixing part 2221 is disposed opposite to the rotating part 2222 to define a limiting cavity 2224. The angle limiting part 2223 moves in the limiting cavity 2224 to control the rotation of the rotating part 2222. The angle limiting part 2223 further includes an elastic element 22231 and an angle limiting member 22232. The elastic element 22231 is placed at the bottom of the angle limiting member 22232. One pressing end 22233 of the angle limiting member 22232 extends out of the fixing part 2221 to press the angle limiting member 22232, so that one limiting end 22234 of the angle limiting member 2223 enters the interior of the rotating part 2222, thereby causing the angle limiting member 22232 to rotate together with the rotating part 2222. When the pressing end 22233 of the angle limiting member 22232 is released, the limiting end 22234 is driven by the elastic element 2221 to the space between the fixing part 2221 and the rotating part 2223, thus limiting the rotation of the rotating part 2222. That is, in the initial position, the pressing end 22233 of the angle limiting member 22232 extends outside the fixing part 2221 for pressing. The limiting end 22234 of the angle limiting member 22232 is disposed between the fixed part 2221 and the rotating part 2222 to restrict the rotation of the rotating part 2222. A set of first blocking members 22211 is provided inside the fixed part 2221, and these first blocking members 22211 are disposed inside the sidewall of the fixed part 2221. Preferably, these first blocking members 22211 are toothed. A set of second blocking members 22221 is provided inside the rotating part 2222, and these second blocking members 22221 are disposed inside the sidewall of the rotating part. The angle limiting member 22232 can be embedded in these second blocking members 22221 to rotate with the rotating part 2222. Preferably, the angle limiting member 22232 is a gear.

[0076] The jaw support device 23 further includes two side supports 231 and a jaw adjustment member 232. The two side supports 231 are respectively disposed on both sides of the jaw support device 23. The two side supports 231 are respectively connected to the two rotating parts 2222, so that the angle of the jaw support device 23 can be adjusted by the two rotating parts 2222 in the direction of rotation. The two ends of the jaw adjustment member 232 are respectively connected to the two ends of the two side supports 231. The jaw adjustment member 232 further includes a support unit 2321 and an adjustment unit 2322. The support unit 2321 is fixed to the adjustment unit 2322. The adjustment unit 2322 is respectively connected to the two side supports 231. The adjustment unit 2322 further includes an adjustment knob 23221 and two adjustment straps 23222. Two adjustment bands 23222 are movably connected to each other, allowing adjustment of the relative position of the two adjustment bands 23222 via the adjustment knob 23221, thereby adjusting the width of the user's jaw. Preferably, the adjustment knob 23221 is provided with a gear. A toothed band 23223 is provided on one side of each of the two adjustment bands 23222. The two toothed bands 23223 of the two adjustment bands 23222 are arranged opposite to each other so that the two toothed bands 23222 respectively contact the gear of the adjustment knob 23221. In this way, by rotating the adjustment knob 23221, the width of the jaw support device 23 is adjusted to accommodate the width of the user's jaw.

[0077] The fixing part 2221 is further provided with a connecting part 22212, which is connected to the side of the rear neck support part 10. Preferably, the rear neck support part 10 is connected to the connecting part 22212 by a connecting strap to fix the rear neck support part 10 to the back of the user's neck.

[0078] It is worth mentioning that the cervical spine fixation device of the present invention provides an adjustment system. For example... Figure 6A , Figure 6B , Figure 7A and Figure 7BAs shown. In the adjustment system, the widths of the jaw support device 23 and the adjustable base 21 are adjusted respectively to adapt the cervical spine fixation device of the present invention to the width of the user's neck. The distance between the jaw support device 23 and the adjustable base 21 is adjusted by adjusting the lengths of the two adjustment devices 22 respectively. This adapts to the length of the user's neck in such a way. It is worth mentioning that, to fit more people's necks, the inventors of the present invention discovered that tilting the head up or down affects the length of the neck. That is, the angle of the jaw support device 23 is adjusted so that the jaw support device 23 can be adjusted upwards or downwards. It is worth mentioning that when the jaw support device 23 is rotated downwards and set to a tilted-head angle, the cervical spine fixation device of the present invention is suitable for people with shorter necks. If the user has a long neck, the jaw support device 23 is rotated upwards so that the jaw support device 23 is set to a tilted-head position, thus adapting to people with long necks.

[0079] The following describes the adjustment system using a user's wearing process. The adjustment platform 20 is worn around the user's neck. During wearing, the user's neck first contacts the adjustable base 21. If the user's neck is wide, the two shoulder supports 211 move away from the user's neck. The adjustment part 212 adapts to the movement of the two shoulder supports 211. In a preferred embodiment of the invention, the adjustment part 212 increases the distance between the two shoulder supports 211 by rotation. When the user's neck moves to the two adjustment devices 22, if the user's neck can continue to move forward, the user's jaw can move to the jaw support device 23 and be supported by the jaw support device 23. If the user's neck is blocked from moving forward by the two adjustment devices 22, the width of the jaw support device 23 needs to be adjusted so that the user's neck can continue to move towards the jaw support device 23. In a preferred embodiment of the present invention, by rotating the adjustment knob 23221, the lengths of the two adjustment straps 23222 are extended respectively, so that the user's neck can continue to move towards the jaw support device 23. When the user's jaw is supported by the jaw support device 23, the user can adjust the jaw support device 23 to fit the user's jaw. Specifically, by rotating the adjustment knob 23221, the two adjustment straps 23222 are moved respectively to shorten the distance between the two side support members 231, thereby making the side support members 231 and the jaw adjustment member 232 fit the user's jaw. It is worth mentioning that during the process of adjusting the jaw support device 22 to fit the user's jaw, the two side support members 231 respectively guide the two adjustment devices 22 to move towards fitting the user's neck, thereby driving the two shoulder support members 211 to move towards fitting the user's neck.

[0080] If the user's neck is short and the jaw support device 22 fails to support it, the height of the jaw support device 23 can be lowered by operating the two knobs 2211 to adjust the two adjustment devices 22. Alternatively, the angle limiting end 22234 can be engaged with the rotating part 2222 by pressing the pressing end 22233. The jaw support device 23 can then be adjusted to rotate downwards, allowing the user's jaw to be supported by it. If the user's neck is long, the jaw support device 23 can be raised using the two adjustment devices 22. The user can further adjust the upward tilt angle of the jaw support device 23 to increase the adjustment height and better suit the length of their neck.

[0081] Reference Appendix Figure 8To be continued Figure 15 As shown, the cervical spine fixation device 8 of the second embodiment of this application is illustrated. Figure 8 and Figure 9 As shown, the cervical spine fixation device 8 includes a cervical support 81, an adjustment strap 82, an adjustment component 83, a width adjustment component 84, and a shoulder support 85. The adjustment component 83 includes a left support body 831 and a right support body 832. The adjustment strap 82 passes through the cervical support 81. Both ends of the adjustment strap 82 are connected to the left support body 831 and the right support body 832, respectively. The width adjustment component 84 is positioned opposite the cervical support 81, maintaining a certain distance from it, and is connected to the left support body 831 and the right support body 832. The adjustment component 83 is mounted on the shoulder support 85. When the user wears the cervical spine fixation device 8, the back of the wearer's neck is supported by the cervical support 81, the width adjustment component 84 supports the wearer's chin, the shoulder support 85 is placed on the wearer's shoulders, and the left support body 831 and the right support body 832 of the adjustment component 83 are located on both sides of the wearer's neck to adjust the height between the width adjustment component 84 and the shoulder support 85 and the tilt angle between the width adjustment component 84 and the adjustment component 83, so that the range of motion of the wearer's neck is precisely limited and fits the wearer.

[0082] For details, please refer to the appendix. Figure 10 To be continued Figure 12 As shown, the width adjustment assembly 84 further includes a left adjustment member 841, a right adjustment member 842, a housing 843, and a width adjustment knob 844. The left adjustment member 841 and the right adjustment member 842 are installed inside the housing 843 and are adapted to slide within the housing 843. The width adjustment knob 844 is rotatably installed in the housing 843 and is adapted to drive the left adjustment member 841 and the right adjustment member 842 to move closer to each other or further apart simultaneously. That is, when the width adjustment knob 844 is rotated, the overall length formed by the left adjustment member 841 and the right adjustment member 842 can be changed. The width adjustment assembly 84 can adjust the width to adapt to the width of the user's jaw. Furthermore, the width adjustment assembly 84 can adjust the width to adapt to the width of the user's neck.

[0083] Furthermore, the left adjusting member 841 further includes a left pivot member 8411 and a left rack 8412. The left pivot member 8411 is disposed at one end of the left adjusting member 841, and the left rack 8412 is disposed at the other end of the left adjusting member 841. The left pivot member 8411 is disposed on one side of the left rack 8412. The left pivot member 8411 is connected to the left side support body 831, and the left rack 8412 extends from the upper edge of the left adjusting member 841 and forms a rack towards the lower edge. The right adjusting member 842 further includes a right pivot member 8421 and a right rack 8422. The right pivot member 8421 is disposed at one end of the right adjusting member 842, and the right rack 8422 is disposed at the other end of the right adjusting member 842. The right pivot member 8421 is disposed on one side of the right rack 8422. The right pivot member 8421 is connected to the right side bracket body 832, and the right rack 8422 extends a certain distance from the lower edge of the right adjusting member 842 and forms a rack towards the upper edge.

[0084] The housing 843 has a left sliding hole 8431 and a right sliding hole 8432 at both ends. The left sliding hole 8431 is aligned with the right sliding hole 8432. The housing 843 has a mounting hole 8434 in the middle. An internal gear ring 8433 is provided above the peripheral wall of the mounting hole 8434. The left rack 8412 of the left adjusting member 841 passes through the left sliding hole 8431 and is positioned below the mounting hole 8434, while the right rack 8422 passes through the right sliding hole 8432 and is positioned below the mounting hole 8434, keeping the left rack 8412 and the right rack 8422 relatively opposite to each other.

[0085] Specifically, the width adjustment knob 844 further includes a set of width adjustment teeth 8441 and a rotation-limiting ratchet tooth 8442. The rotation-limiting ratchet 8422 is disposed above the width adjustment teeth 8411. The width adjustment knob 844 is adapted to be rotatably mounted on the housing 843 through the mounting hole 8434, so that the width adjustment teeth 8441 engage between the left rack 8412 and the right rack 8422, so that when the width adjustment knob 844 rotates, it can drive the left adjustment member 841 and the right adjustment member 842 to move synchronously, thereby changing the distance between the left support body 831 and the right support body 832. When the width adjustment knob 844 rotates, the rotation-limiting ratchet 8442 rotates accordingly. When the width adjustment knob 844 is stationary, the rotation-limiting ratchet 8442 stops rotating to maintain the left rack 8412 and the right rack 8413 in their current positions. In other words, when an external force is applied to the left adjusting member 841 and the right adjusting member 842 respectively, the rotation limiting ratchet 8442 prevents the width adjusting knob 844 from rotating, so as to maintain the left rack 8412 and the right rack 8413 in the current position.

[0086] In a preferred embodiment of this application, the rotation limiting ratchet tooth 8442 ensures that the length adjustment between the left adjusting member 841 and the right adjusting member 842 is limited and can be adjusted in segments. That is, the width adjusting knob 844 is locked after each adjustment to prevent the left adjusting member 841 and the right adjusting member 842 from loosening when under force, thus affecting the fit of the width adjusting component 84 to the wearer.

[0087] Reference Appendix Figure 13 As shown, in detail, the shoulder support 85 further includes a left shoulder support portion 851, a hinge 853, and a right shoulder support portion 852. The end of the left shoulder support portion 851 is hinged to the end of the right shoulder support portion 852 via the hinge 853. Specifically, when the left shoulder support portion 851 is worn, one end rests on the wearer's shoulder, and the other end extends along the wearer's collarbone to the chest. The hinge 851 is mounted at this end. It can be understood that the left shoulder support portion 851 can rotate at a certain angle relative to the right shoulder support portion 852 around the hinge 853.

[0088] When the left shoulder support 851 and the right shoulder support 852 are worn on the wearer's body, the combined support of the wearer's shoulders and chest further ensures the stability of the cervical spine fixation device 8 during wear, allowing it to better fit the wearer. Furthermore, when the width adjustment knob 844 rotates, it causes the left adjustment component 841 and the right adjustment component 842 to move synchronously, thereby changing the distance between the left support body 831 and the right support body 832. This, in turn, causes the left shoulder support 851 and the right shoulder support 852 to rotate around the hinge 853, allowing the width adjustment assembly 84 and the shoulder support 85 to find a more suitable wearing position and angle during adjustment, ensuring stability and a good fit. Specifically, when the width adjustment knob rotates in one direction, the left adjustment component 841 moves closer to the right adjustment component 842, and the right adjustment component 842 moves towards the left adjustment component 841, reducing the width of the width adjustment assembly. It is worth mentioning that when the left adjustment member 841 moves to a preset threshold, it moves the left support body closer to the user's neck, so that the left support body fits the user's neck. When the right adjustment member 841 moves to a preset threshold, it moves the right support body closer to the user's neck, so that the right support body fits the user's neck. When the width adjustment knob is rotated in the other direction, the left adjustment member 841 moves away from the right adjustment member 842, and the right adjustment member 842 moves away from the left adjustment member 841.

[0089] Reference Appendix Figure 14 and attached Figure 15 As shown, the left shoulder support 851 further includes a left height bracket connector 8511, and the right shoulder support 852 further includes a right height bracket connector 8521. The left height bracket connector 8511 is mounted on the left shoulder support 851, and the right height bracket connector 8521 is mounted on the right shoulder support 852.

[0090] The left support body 831 includes a left width adjustment component connector 8311, a left height adjustment knob 8312, a left height adjustment element 8313, and a left pitch adjustment knob 8314. The left height adjustment element 8313 is slidably mounted on the left height support connector 8511. In a preferred embodiment of this application, the left height adjustment element 8313 is implemented as a rack. The left height adjustment knob 8312 is rotatably mounted on the left height support connector 8511 and engages with the left height adjustment element 8313, and can drive the left height adjustment element 8313 to rise and fall when rotated. The left height adjustment element 8313 is also slidably mounted on the left support body 831, so that when the left height adjustment knob 8312 rotates, it drives the left height adjustment element 8313 to rise and fall, and lifts the left support body 831, thereby driving the left support body 831 to adjust its height.

[0091] The right-side support body 832 includes a right width adjustment component connector 8323, a right height adjustment knob 8321, a right height adjustment member 8322, and a right pitch adjustment knob 8324. The right height adjustment member 8322 is slidably mounted on the right height support connector 8521. In a preferred embodiment of this application, the left height adjustment member 8313 is implemented as a rack. The right height adjustment knob 8321 is rotatably mounted on the right height support connector 8521 and engages with the right height adjustment member 8322, and can drive the right height adjustment member 8322 to rise and fall when rotated. The right height adjustment member 8322 is slidably mounted on the right-side support body 832, so that when the right height adjustment knob 8321 rotates, it drives the right height adjustment member 8322 to rise and fall, and lifts the right-side support body 832, thereby driving the right-side support body 832 to adjust its height.

[0092] The left tilt adjustment knob 8314 pivots to mount the left width adjustment component connector 8311 to the left support body 831, and the left pivot connector 8411 is connected to the left width adjustment component connector 8311. It is understood that pressing the left tilt adjustment knob 8314 unlocks the fixed relationship between the left width adjustment component connector 8311 and the left support body 831, allowing the left width adjustment component connector 8311 to rotate around the left tilt adjustment knob 8314. In a preferred embodiment of the invention, the left tilt adjustment knob 8314 is located on one side of the left support body 831. Preferably, the left tilt adjustment knob 8314 is located near the left support body 831 on the side furthest from the width adjustment component 84.

[0093] The right pitch adjustment knob 8324 pivots to mount the right width adjustment component connector 8323 to the right side support body 832. The right pivot connector 8421 is connected to the right width adjustment component connector 8323. By pressing the right pitch adjustment knob 8324, the fixed relationship between the right width adjustment component connector 8323 and the right side support body 832 is unlocked, allowing the right width adjustment component connector 8323 to rotate around the right pitch adjustment knob 8324. In a preferred embodiment of the present invention, the right pitch adjustment knob 8324 is located on one side of the right side support body 832. Preferably, the right pitch adjustment knob 8324 is located near the right side support body 832, away from the width adjustment component 84.

[0094] In other words, the angle between the width adjustment component 84 and the adjustment component 83 is adjusted synchronously by the left tilt adjustment knob 8314 and the right tilt adjustment knob 8324, so that the relative positional relationship between the width adjustment component 84 and the adjustment component 83 is more suitable for the wearer. In this embodiment, the adjustment strap 82 is preferably implemented as an elastic band. The adjustment strap 82 passes through the rear neck support 81, with one end connected to the left support body 831 and the other end connected to the right support body 832, thereby connecting the rear neck support 81 to the adjustment component 83. Those skilled in the art should understand that the adjustment strap 82 can also be implemented in other ways, including but not limited to the embodiments listed above. It is worth mentioning that this application further provides a fastening fixing method. The cervical spine fixator 8 further includes a fixing device 87. The fixing device 87 further includes a fixing member 871 and a fastener 872. The fastener 872 fastens the fixing member to fix the rear neck support through the adjustment strap 82. In a preferred embodiment of this application, the fastener 871 is implemented as a fixing post 8711. The fastener 872 has a fastening hole 8721 in its center, the diameter of which is slightly larger than the diameter of the fixing post 8711, to allow the fixing post 8711 to be inserted and thus fixed. The fastener 872 further includes a strap interface 8722. The strap interface 8722 is located on one side of the fastening hole 8721. The strap interface 8722 allows the adjusting strap 82 to pass through. That is, the fastener 872 provides two fixing methods: one is to first fix the fastener 872 to the fixing post 8711, and then adjust it to a suitable length using the adjusting strap 82 to fix the rear neck brace; the other is to first adjust the adjusting strap 82 to a suitable length, and then fix the fastening hole 8721 to the fixing post 8711.

[0095] The cervical spine fixation device 8 also includes a flexible support component 86, which further includes a neck flexible support unit 861, a jaw flexible support unit 862, and a shoulder flexible support unit 863. The neck flexible support unit 861 is disposed on the rear neck brace 81, and the jaw flexible support unit 862 is disposed on the width adjustment component 84, the left width adjustment component connector 8311, and the right width adjustment component connector 8323. It can be understood that the jaw flexible support unit 862 is a split design in this embodiment to better adapt to the wearer's chin. The shoulder flexible support unit 863 is disposed below the shoulder brace 85. When the wearer wears the device, the neck flexible support unit 861 fills the space between the wearer and the rear neck brace 81, the jaw flexible support unit 862 fills the space between the wearer and the width adjustment component 84, and the shoulder flexible support unit 863 fills the space between the wearer and the shoulder brace 85, thereby flexibly supporting the wearer, relieving the wearer's wearing pressure, and improving the comfort of wearing the device.

[0096] When worn, the neck is supported by the cervical support 81, and the chin is supported by the width adjustment component 84. The head is supported by the adjustment component 83, further restricting the movement of the cervical spine. The height between the width adjustment component 84 and the shoulder support 85 is adjusted by the left height adjustment component 8313 and the right height adjustment component 8322 to accommodate different neck lengths and wearing height requirements of different wearers. The angle position of the width adjustment component 84 relative to the adjustment component 83 is controlled by the left tilt adjustment knob 8314 and the right tilt adjustment knob 8324. In particular, the width adjustment component 84 can adapt to the width of the wearer's chin and can be adjusted in conjunction with the shoulder support 85, thereby strengthening the fit of the cervical spine fixation device 8 to the various support parts of the wearer and further improving the wearer's wearing experience.

[0097] As attached Figure 16The image shown is a third preferred embodiment of this application. Unlike the second embodiment, in this embodiment, the jaw flexible support unit 864 includes a flexible support unit 8641 and a pair of straps 8642. The straps 8642 are fixed to both sides of the flexible support unit 8641. The flexible support unit 8641 is disposed on the housing 843 and extends from both ends to the left width adjustment component connector 8311 and the right width adjustment component connector 8323. The straps 8642 are elastically bound to the left width adjustment component connector 8311 and the right width adjustment component connector 8323. It can be understood that when the width adjustment component 84 is adjusted, the straps 8642 can slide along with the left width adjustment component connector 8311 and the right width adjustment component connector 8323, thereby ensuring that the width adjustment component 84 does not affect the support and fit of the flexible support unit 8641 to the wearer when adjusting. The basic principles of this application have been described above with reference to specific embodiments. However, it should be noted that the advantages, benefits, and effects mentioned in this application are merely examples and not limitations, and should not be considered as essential features of each embodiment of this application. Furthermore, the specific details disclosed above are for illustrative and facilitative purposes only, and are not limitations. These details do not limit the application to the necessity of employing the aforementioned specific details. The functional and structural principles of this application have been demonstrated and explained in the embodiments. Without departing from the described principles, the implementation of this invention can undergo any modifications or variations.
