[0031] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0032] In the following detailed description, reference may be made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration specific embodiments in which the application may be practiced. In the drawings, like reference numerals describe substantially similar components in different figures. The various specific embodiments of this application are described in sufficient detail below to enable those of ordinary skill in the art with relevant knowledge and technology to implement the technical solutions of this application. It should be understood that other embodiments may be utilized or structural, logical or electrical changes may be made to the embodiments of this application.

[0033] The technical solutions of this application will be further described below through specific embodiments. Those skilled in the art should understand that the following description is only for the convenience of understanding the technical solutions of this application and should not be used to limit the scope of protection of this application.

[0034] This application provides an orthopedic support member. By placing an elastic member between the spinous processes for support, the intervertebral height can be restored to achieve a decompression effect. Among them, the elastic member placed between the spinous processes uses a binding band to respectively bind and fix adjacent spinous processes, which can prevent the binding band from slipping, thereby realizing the movement stability and controllable movement of the lumbar spine structure. The orthopedic support member also includes an interlaminar support member for supporting and fixing the spinous process member, which can realize the support between the laminae while realizing the support of the spinous process, and plays an important role in maintaining spinal stability, dispersing pressure, restoring and maintaining the normal spinal curvature, promoting healing, relieving pain, preventing disc herniation, and improving function.

[0036] Figure 2 is a side view schematic diagram of an orthopedic support member according to another embodiment of this application.

[0037] Figure 3 According to Figure 1 is a front view schematic diagram of an orthopedic support member of the embodiment.

[0038] Since the spinous process is a sheet-like bone with one end connected to the spine and the other end extending away from the spine, for the convenience of subsequent description, the plane in which the spinous process extends and the plane perpendicular thereto can be defined.

[0039] According to one embodiment, as Figure 1 shown, the orthopedic support member 1 includes a lamina support member 20 and a spinous process support member 10. According to one embodiment, the spinous process support member 10 includes a first portion 101, a second portion 102, and a third portion 103. Among them, the first portion 101 and the second portion 102 are separated from each other and respectively support or contact different spinous processes; the third portion 103 of the spinous process support member 10 is located between the first portion 101 and the second portion 102. There is a space between the first portion 101 and the second portion 102, and this space opens at one end away from the third portion 103.

[0040] According to one embodiment, different straps can be used to respectively bind the first portion 101 and the second portion 102 to different spinous processes. Therefore, the risk of fracture caused by bundling different spinous processes together and restricting the range of motion of the user can be avoided.

[0041] According to one embodiment, as Figure 3 shown, the projection of the spinous process support member 10 in a plane perpendicular to the spinous process extension plane can basically have an inverted trapezoidal shape, that is, a shape that is wider at the top and narrower at the bottom. According to one embodiment, the upper surface 104 of the first portion 101 of the spinous process support member 10 and the lower surface 105 of the second portion 102 have arc surfaces facing away from each other, wherein the radian of the upper surface 104 of the first portion 101 can be greater than the radian of the lower surface 105 of the second portion 102. The end of the spinous process support member 10 that is open away from the first portion 101 and the second portion 102 is connected to the lamina support member 20.

[0042] According to one embodiment, as Figure 1 shown, the inner surfaces of the first portion 101 of the spinous process support member 10 and the second portion 102 of the spinous process support member 10 facing the isolation space can have a structure for preventing the strap from slipping. For example, the second surface 106 of the first portion 101 of the spinous process support member 10 in contact with the strap and the second surface 107 of the second portion 102 of the spinous process support member 10 in contact with the strap can have a circular arc or groove for accommodating the strap.

[0043] According to another embodiment, as Figure 2 shown, the surface 106 of the first portion 101 of the spinous process support member 10 in contact with the strap and located in the isolation space and the surface 107 of the second portion 102 of the spinous process support member 10 in contact with the strap and located in the isolation space can have, for example, a serrated structure to prevent the strap from slipping. According to one embodiment, the serrations can be inclined or tilted towards the third portion 103 of the spinous process support member 10, so that it can be more convenient to prevent the strap from slipping, or it can hook the strap.

[0044] According to another embodiment, the first part 101 or the second part 102 of the spinous process support 10 may include through holes (not shown) for fixing the strap. For example, the strap can pass through the space between the first part 101 and the second part 102 and pass through two holes in the first part 101 or the second part 102, without having to go around from the outside of 101 or 102.

[0045] Figure 4 Figure 4 is a side view schematic diagram of an orthopedic support according to another embodiment of the present application.

[0046] Figure 5 For Figure 4 Figure 5 is a front view schematic diagram of an orthopedic support according to an embodiment.

[0047] According to an embodiment, the spinous process support 10 may further include a fourth part 108 that is isolated from both the first part 101 and the second part 102. One end of the fourth part 108 is fixed to the third part 103, and the other end extends in a direction away from the third part 103. In this embodiment, the projection shape of the spinous process support 10 in the plane extending along the spinous process may be similar to the shape of the letter "E".

[0048] According to an embodiment, the distance between the first part 101 and the second part 102 of the spinous process support 10 and the intermediate fourth part 108 may gradually increase inward from the opening position, which can increase the difficulty of the strap slipping off the first part 101 and the second part 102, and help prevent the strap from slipping.

[0049] According to an embodiment, the position of the fourth part 108 between the first part 101 and the second part 102 can be adjusted as needed. For example, the distance between the fixing point between the third part 103 and the fourth part 108 and the first part 101 and the second part 102 can be equal or unequal, thereby changing the position of the center of gravity of the spinous process support 10, and the desired stable effect can be achieved.

[0051] Figure 7 For Figure 6 Figure 7 is a front view schematic diagram of an orthopedic support according to an embodiment.

[0052] According to one embodiment, the spinous process support 10 may further include a fifth portion 109 that is isolated from the first portion 101, the second portion 102, and the third portion 103. The fifth portion 109 may be located at an end of the fourth portion 108 away from the third portion 103, extend along a plane substantially parallel to the third portion 103, and may partially or completely block the opening of the gap between the first portion 101 and the fourth portion 108 or between the second portion 102 and the fourth portion 108.

[0053] According to one embodiment, the fifth portion 109 may be located outside the gap space between the first portion 101 and the second portion 102 as shown in the figure, or may be located inside the gap space, but there is still a gap reserved between the fifth portion 109 and the first portion 101 and the second portion 102 for the entry of the strap.

[0054] Of course, since the material of the fifth portion 109 is a flexible material, if its thickness is relatively thin, it can completely block the opening or gap between the first portion 101 and the second portion 102. When the strap enters the isolation space, the fifth portion 109 is completely exposed at the opening. After the strap enters the isolation space, the fifth portion 109 can be released to block the opening of the isolation space.

[0055] According to one embodiment, the projection of the fifth portion 109 of the spinous process support 10 in a plane perpendicular to the spinous process extension plane may have a shape similar to an inverted trapezoid, and the shape of each side does not exceed the range of the projections of the first portion 101, the second portion 102, and the third portion 103 in a plane perpendicular to the spinous process extension plane. According to one embodiment, the left and right edges of the fifth portion 109 are substantially aligned with the left and right sides of the first portion 101 or the second portion 102. According to one embodiment, the gap between the fifth portion 109 and the first portion 101 and the second portion 102 is small enough to prevent the strap from completely slipping off from the first portion 101 or the second portion 102, but at the same time allows the user to insert the strap into the isolation space between the first portion 101 and the second portion 102 through this gap when installing the strap.

[0056] According to one embodiment, the fifth portion 109 of the spinous process support 10 may include two separated sub-portions (not shown), each fixed to the fourth portion 108, and partially or completely blocking both ends of the isolation space between the first portion 101 and the second portion 102 in a plane perpendicular to the spinous process extension plane.

[0058] Figure 9 For Figure 8 Schematic front view of an orthopedic support according to an embodiment.

[0059] According to one embodiment, the spinous process support 10 may include a first part 101, a second part 102, a third part 103, and a sixth part 110. The sixth part 110 is similar to the third part 103 and also connects the mutually separated first part 101 and second part 102, but is located at an end opposite to the third part 103. According to different embodiments, the sixth part 110 may be fixedly connected to the first part 101 and / or the second part 102, or may be flexible. For example, after the first part 101, the second part 102, and the third part 103 are installed, the sixth part 110 is then inserted between the first part 101 and the second part 102 for support and fixation. Different straps may pass through the isolation space formed by the first part 101, the second part 102, the third part 103, and the sixth part 110 and be respectively fixed to the first part 101, the second part 102, and the upper and lower spinous processes.

[0061] Figure 11 According to Figure 10 Top view schematic diagram of an orthopedic support according to an embodiment.

[0062] As shown in the figure, the lamina support 20 is connected to an end of the third part 103 of the spinous process support 10 that is far from the first part 101 and the second part 102 and protrudes in a direction away from the spinous process support 10. According to one embodiment, in the vertical plane of the spinous process extension surface, the projection of the spinous process support 10 is a sector ring, wherein the radian of the upper surface or the first surface 201 of the lamina support 20 is smaller than the radian of the lower surface or the second surface 202, the third surface 203 in contact with the spine is a plane, and the fourth surface 204 and the fifth surface 205 of the lamina support 20 on both sides of the third surface 203 are symmetrically distributed and are inwardly curved surfaces. The overall size of the lamina support 20 is smaller than that of the spinous process support 10.

[0063] According to one embodiment, the width W1 of the lamina support 20 may be 2 mm - 6 mm, the height H1 may be 5 mm - 12 mm, and the length L1 may be 10 mm - 17 mm.

[0064] According to one embodiment, the height H2 of the spinous process support 10 may be 15 mm - 25 mm, the length L2 may be 20 mm - 40 mm, and the width W2 may be 10 mm - 20 mm.

[0066] Figure 13Front elevation schematic view of the orthopedic support in use according to an embodiment of the present application.

[0067] As shown in the figure, the lamina support 20 is placed in the gap between the first lamina 300 and the second lamina 301 to achieve the function of spreading the two laminae. At this time, the first surface 104 of the first part 101 of the spinous process support 10 abuts against the first spinous process 302, and the first surface 105 of the second part 102 abuts against the second spinous process 303. The first strap 304 is tied and fixed to the first part 101 of the spinous process support 10, and the second strap 305 is tied and fixed to the second part 102 of the spinous process support 10 to prevent the orthopedic support 1 from loosening and falling. According to an embodiment, the lamina support 20 and the spinous process support 10 can be integrally formed.

[0068] According to an embodiment, the joints of the surfaces of the orthopedic support 1 are arc-shaped, and all can fit well with the biological anatomical structure.

[0069] In order to prevent damage to the spine and its surrounding tissues and ensure the support hardness of the support system, the orthopedic support 1 and the straps are made of polymer materials, such as elastomers like silicone rubber and TPU. And the lamina support 20 can have a hydrophilic coating or adhesive sheet to prevent soft tissue adhesion. The selected materials all have good biocompatibility. In some embodiments, the strap part can be fixed using a buckle.

[0070] The orthopedic support of the present application can restore the physiological curvature of the spine, relieve the pain caused by nerve root compression, and at the same time 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 movement more flexible after surgery by simultaneously supporting the lamina and the spinous process and adopting the method of separately tying the spinous processes.

[0071] The above embodiments are only for illustrating the present application and are not a limitation of the present application. Those of ordinary skill in the relevant technical field can make various changes and modifications without departing from the scope of the present application. Therefore, all equivalent technical solutions should also fall within the scope of the disclosure of the present application.
