DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] In the following detailed description, reference may be made to the various specification drawings that are part of the present application and are used to illustrate specific embodiments of the present application. In the accompanying drawings, similar reference numerals describe substantially similar components in different figures. The various specific embodiments of the present application are described below in sufficient detail so that a person of ordinary skill in the art with relevant knowledge and skills in the art can implement the technical solutions of the present application. It should be understood that other embodiments may also be used or structural, logical or electrical changes may be made to the embodiments of the present application.

[0017] The technical solution of the present application is further described below through specific implementation methods. Those skilled in the art should understand that the following description is only for the convenience of understanding the technical solution of the present application and should not be used to limit the protection scope of the present application.

[0018] The present application provides an orthopedic support component, which can restore the intervertebral height and achieve the effect of decompression by placing elastic components between the spinous processes for support, wherein the elastic components placed between the spinous processes use their own structure to clamp and fix the adjacent spinous processes respectively, without the need for straps or bone screws to fix, and can prevent the orthopedic support component from slipping, thereby achieving the activity stability and controllable movement of the lumbar structure. The orthopedic support component also includes an intervertebral support component supported and fixed by the spinous process component, which can achieve support between the vertebral plates while achieving spinous process support, and plays an important role in maintaining spinal stability, dispersing pressure, restoring and maintaining normal spinal curvature, promoting healing, alleviating pain, preventing intervertebral disc herniation, and improving function.

[0019] Since the spinous process is a plate-like bone that is connected to the spine at one end and extends away from the spine at the other end, in order to facilitate subsequent description, the plane in which the spinous process extends and the plane perpendicular to it can be defined.

[0020] Figure 1 It is a schematic side view of an orthopedic support according to one embodiment of the present application.

[0021] Figure 2 Shown is Figure 1 A schematic front view of an orthopedic support according to an embodiment of the present application is shown.

[0022] According to one embodiment, the orthopedic support includes a lamina support 20 and a spinous process support 10 .

[0023] According to one embodiment, the spinous process support 10 includes a first portion 101, a second portion 102 and a third portion 103, wherein the third portion 103 of the spinous process support 10 is connected between the first portion 101 and the second portion 102. According to one embodiment, the first portion 101 and the second portion 102 extend in opposite directions, specifically, the first portion 101 extends in the direction of the upper edge of the first spinous process, and the second portion 102 extends in the direction of the lower edge of the second spinous process.

[0024] According to one embodiment, the projection of the third part 103 of the spinous process support 10 in a plane perpendicular to the spinous process extension plane can basically have an inverted trapezoidal shape, that is, a shape that is wide at the top and narrow at the bottom. According to one embodiment, the first surface 1031 and the second surface 1032 of the third part 103 of the spinous process support 10 have arc surfaces facing each other, wherein the curvature of the first surface 1031 can be greater than the curvature of the second surface 1032. According to one embodiment, the first surface 1031 of the third part 103 is connected to the first part 101, and the second surface 1032 of the third part 103 is connected to the second part 102, respectively, for supporting or contacting two adjacent spinous processes. The spinous process support 10 is connected to the lamina support 20 at the end close to the spine.

[0025] According to one embodiment, the size of the space formed between the first part 101 and the second part 102, that is, the size of the third part 103, can be adjusted as needed, thereby solving the problem of different spinous process sizes of different users.

[0026] According to one embodiment, the interior of the third part 103 of the spinous process support 10 can be solid or hollow. In the case of being hollow, openings can be set at appropriate positions on the surface of the third part 103. During surgery, the air inside the third part 103 can be released through the openings to facilitate its placement between the spinous processes without affecting the subsequent support effect.

[0027] According to one embodiment, the first portion 101 may include two sub-portions located on the left and right sides of the first spinous process, and the two sub-portions may be symmetrically distributed. According to one embodiment, the two sub-portions of the first portion 101 of the spinous process support 10 may be approximately elliptical in shape, and the sizes of the two sub-portions become smaller and contracted at the spatial opening position, and the inner surfaces of the two sub-portions are consistent with the shape of the spinous process surface they contact.

[0028] The space between the two can accommodate the first spinous process. According to one embodiment, the two sub-parts may not be closed to each other, and the space opening between the two is away from the third part 103. And, according to one embodiment, the distance between the two sub-parts, at least the distance at the position of the space opening between the two, can be less than the width of the first spinous process at that position, so that the spinous process can be better limited and fixed. Since the material of the orthopedic support is an elastic material, when the first spinous process is inserted into the space, the two sub-parts can be spread apart for accommodation. Since the first part 101 mainly contacts the lower surface and both sides of the first spinous process, and the spinous process has a gradually changing shape from small at the top to large at the bottom, the distance between the two sub-parts of the first part 101 can gradually decrease along the spinous process upward.

[0029] According to another embodiment, the two sub-portions of the first portion 101 may be closed or in contact or engaged with each other above the upper edge of the spinous process.

[0030] According to one embodiment, the second part 102 of the spinous process support 10 may include two sub-parts, which may be symmetrically distributed. The space between the two can accommodate the second spinous process. According to one embodiment, the two sub-parts may not be closed to each other, and the space opening between the two is away from the third part 103. And, according to one embodiment, the distance between the two sub-parts, at least the distance at the position of the space opening between the two, may be less than the width of the second spinous process at that position, so that the spinous process can be better limited and fixed. Since the material of the orthopedic support is an elastic material, when the second spinous process is inserted into the isolation space, the two sub-parts can be spread apart for accommodation. Since the second part 102 mainly contacts the upper surface and both sides of the second spinous process, and the spinous process has a gradually changing shape from small at the top to large at the bottom, the distance between the two sub-parts of the second part 102 can gradually increase along the spinous process downward.

[0031] According to one embodiment, each sub-portion of the second portion 102 of the spinous process support 10 may be approximately trapezoidal in shape, with the long side close to the third portion 103 and the short side away from the third portion 103, and the inner surface conforms to the shape of the contacting spinous process surface.

[0032] Of course, according to another embodiment, the two sub-portions of the second portion 102 may also have a substantially symmetrical shape and positional relationship with the two sub-portions of the first portion 101 .

[0033] According to one embodiment, the first portion 101, the second portion 102, and the third portion 103 of the spinous process support 10 may be integrally formed.

[0034] Since the first part 101 and the second part 102 of the spinous process support 10 fix different spinous processes respectively, the effect of supporting the spinous process can be ensured, and the range of motion of the patient can be not restricted. In addition, the first part 101 and the second part 102 of the spinous process support 10 have an open structure. Compared with a bandage, it can fix the basic position of the spinous process and avoid overly rigid binding of the spinous process, providing a certain degree of flexibility, so it can provide better flexibility and stability for the user.

[0035] According to one embodiment, the first part 101 and the second part 102 of the spinous process support 10 may also be a spinous process sleeve (not shown) wrapped around the spinous process. According to one embodiment, the spinous process sleeve may be made of a flexible material with elasticity. According to one embodiment, the size of the spinous process sleeve when not stretched is smaller than the size of the spinous process. When the spinous process sleeve is stretched and sleeved on the spinous process, the spinous process can be firmly fixed without affecting the flexibility of the spinous process.

According to one embodiment, the spinous process support 30 comprises a first portion 301, a second portion 302 and a third portion 303, wherein the first portion 301 and the second portion 302 are detachably fixed to the third portion 303.

[0037] According to one embodiment, the projection of the third part 303 in a plane perpendicular to the spinous process extension plane can basically have an inverted trapezoidal shape, that is, a shape that is wide at the top and narrow at the bottom. According to one embodiment, the first surface or upper surface 3031 and the second surface or lower surface 3032 of the third part 303 have arc surfaces facing each other, wherein the arc of the first surface 3031 can be greater than the arc of the second surface 3032. The spinous process support 30 is connected to the lamina support 40 at the end close to the spine. According to one embodiment, the shape of the corresponding first part 301 or the second part 302 can be designed according to factors such as the size and shape of the spinous process to be supported. According to one embodiment, the inner surface of the first part 301 and / or the second part 302 can fit the shape of the spinous process supported and contacted, thereby achieving a fixing effect. In general, the first part 301 and / or the second part 302 can have an arc or triangular shape for hanging or carrying or pocketing on the spinous process. According to one embodiment, the first part 301 and / or the second part 302 may be a closed or separated structure, and the separated first part 301 and / or the second part 302 may respectively fix different positions of the same spinous process.

[0038] According to one embodiment, the end of the first part 301 or the second part 302 may include a foot-shaped structure, and the width of the foot-shaped structure may be greater than the width of other positions of the first part 301 or the second part 302, so as to cooperate with the structure in the third part 303 to achieve a fixing effect. According to one embodiment, as Figure 7 As shown, one side (outer side or inner side), or both sides, and / or the bottom side of the foot-like structure may have a tooth-like structure 3011.

[0039] According to one embodiment, Figure 5As shown, the third part 303 of the spinous process support 30 may include two channels 3033 opened on the upper surface or the first surface 3031 for accommodating the end of the first part 301, and the width of the end of the channel 3033 is greater than the width of other areas of the channel 3033 to accommodate the foot-like structure of the first part 301. According to one embodiment, a tooth-like structure 3035 may be provided on the side wall and / or bottom surface on one or both sides of the end of the channel 3033, which is used to engage with the tooth-like structure 3011 on the foot-like structure of the first part 301 to achieve a fixing effect. According to one embodiment, the thickness of the third part 303 can be designed as needed. When the thickness of the third part 303 has a certain range, the foot-like structure of the first part 301 can be fixed or engaged at different positions in the channel 3033 of the third part 303 according to actual conditions, thereby achieving more targeted fixation and support. According to another embodiment, the second part 302 may have a structure and shape similar to the first part 301, and the third part 303 may also have two corresponding channels opening on the lower surface or the second surface 3032 for accommodating and fixing the end of the second part 302, which will not be repeated here.

[0040] Optionally, according to one embodiment, the design of the tooth-like structure 3035 in the channel 3033 of the third part 303 can make the first part 301 and / or the second part 302 pass only in one direction, that is, they can only move forward but not backward. According to one embodiment, the tooth-like structure 3035 at the end of the channel 3033 is uniformly inclined toward the spine, so that the foot-like structure can only move in one direction.

[0041] Optionally, the end side wall or bottom surface of the channel of the third part 303 may have a tooth-like structure, and the foot-like structure of the first part 301 or the second part 302 may have a protrusion for engaging and fixing with the tooth-like structure in the channel.

[0042] According to another embodiment, except for the foot-like structure and the portion in the channel, the first portion 301 and the second portion 302 may have the same Figure 1 The first part 101 and the second part 102 may have similar shapes, or other shapes designed as needed.

[0044] Fig. 9 Shown is Figure 8 A schematic top view of a portion of an orthopedic support of the illustrated embodiment.

[0045] According to one embodiment, the lamina support 40 is connected to the spinous process support 30 at one end close to the spine and bulges in the direction away from the spinous process support 30. According to one embodiment, the projection of the lamina support 40 in the vertical plane of the spinous process extension surface is a fan ring, wherein the curvature of the upper surface or the first surface 401 of the lamina support 40 is smaller than the curvature of the lower surface or the second surface 402, the third surface 403 in contact with the spine is a plane, and the fourth surface 404 and the fifth surface 405 of the lamina support 40 located on both sides of the third surface 403 are symmetrically distributed and are inward curved surfaces. The overall size of the lamina support 40 is smaller than that of the spinous process support 30.

[0046] According to one embodiment, the lamina support 40 may have a width W1 of 2 mm to 6 mm, a height H1 of 5 mm to 12 mm, and a length L1 of 10 mm to 17 mm.

[0049] Fig.11 Shown is Fig.10 The schematic front view of the orthopedic support component of the illustrated embodiment is in use.

[0050] As shown in the figure, the vertebral plate support 20 is placed in the gap between the first vertebral plate 500 and the second vertebral plate 501 to achieve the function of spreading the two vertebral plates. At this time, the first surface 1031 of the third part 103 of the spinous process support 10 abuts against the first spinous process 502, and the second surface 1032 of the third part 103 abuts against the second spinous process 503. The first part 101 of the spinous process support 10 is fixed to the first spinous process 502, and the second part 102 of the spinous process support 10 is fixed to the second spinous process 503 to prevent the orthopedic support from loosening and falling.

[0051] According to one embodiment, the connection points of the surfaces of the orthopedic support are arc-shaped, which can better fit the biological anatomical structure.

[0052] In order to prevent damage to the spine and its surrounding tissues while ensuring the support hardness of the support system, the orthopedic support component is made of polymer materials, such as silicone rubber, TPU and other elastomers, and the vertebral plate support component can have a hydrophilic coating or adhesive sheet to prevent soft tissue adhesion. The selected materials have good biocompatibility.

[0053] The orthopedic support component of the present application can restore the physiological curvature of the spine and relieve the pain of nerve root compression by supporting the vertebral plate and spinous process at the same time and supporting and fixing the spinous process separately. At the same time, it can achieve the stability and controllability of the lumbar structure movement, simulate the original movement of the lumbar spine, ensure the dynamic movement of the spine, and make the patient's postoperative movement more flexible.

[0054] The above embodiments are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention.
