[0024] Figure 3 Based on Figure 1 A schematic front view of an orthopedic support according to an embodiment.

[0025] 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.

[0026] According to one embodiment, Figure 1As shown, the orthopedic support 1 includes a lamina support 20 and a spinous process support 10. 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 first portion 101 and the second portion 102 are separated from each other and support or contact different spinous processes respectively; the third portion 103 of the spinous process support 10 is located between the first portion 101 and the second portion 102. A space is included between the first portion 101 and the second portion 102, and the space is opened at one end away from the third portion 103.

[0027] According to one embodiment, different binding straps can be used to bind the first part 101 and the second part 102 to different spinous processes, respectively, so as to avoid the risk of fracture caused by binding different spinous processes together to limit the range of motion of the user.

[0028] According to one embodiment, Figure 3 As shown, the projection 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 upper surface 104 of the first part 101 and the lower surface 105 of the second part 102 of the spinous process support 10 have curved surfaces facing each other, wherein the curvature of the upper surface 104 of the first part 101 can be greater than the curvature of the lower surface 105 of the second part 102. One end of the spinous process support 10 away from the openings of the first part 101 and the second part 102 is connected to the lamina support 20.

[0029] According to one embodiment, Figure 1 As shown, the inner surface of the first part 101 of the spinous process support 10 and the second part 102 of the spinous process support 10 facing the isolation space may have a structure for preventing the bandage from slipping off. For example, the second surface 106 of the first part 101 of the spinous process support 10 in contact with the bandage and the second surface 107 of the second part 102 of the spinous process support 10 in contact with the bandage may have an arc shape or a groove for accommodating the bandage.

[0030] According to another embodiment, Figure 2 As shown, the surface 106 located in the isolation space where the first part 101 of the spinous process support 10 contacts the bandage and the surface 107 located in the isolation space where the second part 102 of the spinous process support 10 contacts the bandage can have, for example, a sawtooth structure to prevent the bandage from slipping off. According to one embodiment, the sawtooth can be tilted or inclined toward the third part 103 of the spinous process support 10, which can more easily prevent the bandage from slipping off, or in other words, can hook the bandage.

[0031] According to another embodiment, the first part 101 or the second part 102 of the spinous process support 10 may include a through hole (not shown) for fixing a strap, for example, the strap can pass through the space between the first part 101 and the second part 102 and pass out from the two holes of the first part 101 or the second part 102 without having to go around from the outside of 101 or 102.

[0032] Figure 4 It is a schematic side view of an orthopedic support according to yet another embodiment of the present application.

[0033] Figure 5 Based on Figure 4 A schematic front view of an orthopedic support according to an embodiment.

[0034] According to one embodiment, the spinous process support 10 may further include a fourth portion 108 isolated from the first portion 101 and the second portion 102, wherein one end of the fourth portion 108 is fixed to the third portion 103, and the other end extends in a direction away from the third portion 103. In this embodiment, the projection shape of the spinous process support 10 along the spinous process extension plane may be similar to an E-shape.

[0035] According to one embodiment, the distance between the first part 101 and the second part 102 of the spinous process support 10 and the middle fourth part 108 can be gradually increased from the opening position inward, 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 off.

[0036] According to one 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 distances between the fixed points between the third part 103 and the fourth part 108 relative to 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, thereby achieving the stabilization effect that the user desires to achieve.

[0037] Figure 6 It is a schematic side view of an orthopedic support component according to another embodiment of the present application.

[0038] Figure 7 Based on Figure 6 A schematic front view of an orthopedic support according to an embodiment.

[0039] According to one embodiment, the spinous process support 10 may also include a fifth part 109 isolated from the first part 101, the second part 102 and the third part 103, which may be located at an end of the fourth part 108 away from the third part 103 and extend along a surface substantially parallel to the third part 103, and may partially or completely block the opening of the interval between the first part 101 and the fourth part 108 or between the second part 102 and the fourth part 108.

[0040] According to one embodiment, the fifth portion 109 may be located outside the interval between the first portion 101 and the second portion 102 as shown in the figure, or may be located inside the interval while still leaving a gap between the first portion 101 and the second portion 102 for the strap to enter.

[0041] Of course, since the material of the fifth part 109 is flexible material, if its thickness is relatively thin, it can completely block the opening or gap between the first part 101 and the second part 102, and when the strap enters the isolation space, the fifth part 109 is completely exposed to the opening. After the strap enters the isolation space, the fifth part 109 can be released to block the opening of the isolation space.

[0042] According to one embodiment, the projection of the fifth part 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 thereof does not exceed the range of the projection of the first part 101, the second part 102 and the third part 103 in a plane perpendicular to the spinous process extension plane. According to one embodiment, the left and right edges of the fifth part 109 are substantially aligned with the left and right edges of the first part 101 or the second part 102. According to one embodiment, the gap between the fifth part 109 and the first part 101 and the second part 102 is small enough to prevent the strap from completely slipping off the first part 101 or the second part 102, but at the same time allows the user to move the strap from the gap into the isolation space between the first part 101 and the second part 102 when installing the strap.

[0043] According to one embodiment, the fifth portion 109 of the spinous process support 10 may include two sub-portions (not shown) separated from each other, each of which is fixed to the fourth portion 108, partially or completely blocking the isolation space between the first portion 101 and the second portion 102 at both ends of the vertical plane of the spinous process extension surface.

[0044] Figure 8 It is a schematic side view of an orthopedic support according to other embodiments of the present application.

[0045] Fig. 9 Based on Figure 8 A schematic front view of an orthopedic support according to an embodiment.

[0046] According to one embodiment, the spinous process support 10 may include a first portion 101, a second portion 102, a third portion 103, and a sixth portion 110. The sixth portion 110 is similar to the third portion 103, and also connects the first portion 101 and the second portion 102 that are separated from each other, but is located at an end opposite to the third portion 103. According to different embodiments, the sixth portion 110 may be fixed to the first portion 101 and / or the second portion 102, or may be flexible, for example, after the first portion 101, the second portion 102, and the third portion 103 are installed, the sixth portion 110 is inserted between the first portion 101 and the second portion 102 for support and fixation. Different straps may pass through the isolation space created by the first portion 101, the second portion 102, the third portion 103, and the sixth portion 110, and be fixed to the first portion 101, the second portion 102, and the upper and lower spinous processes, respectively.

[0047] Fig.10 It is a schematic rear view of an orthopedic support according to one embodiment of the present application.

[0048] Fig.11 Based on Fig.10 A schematic top view of an orthopedic support component of an embodiment.

[0049] As shown in the figure, the lamina support 20 is connected to one end of the third part 103 of the spinous process support 10 away from the first part 101 and the second part 102, and protrudes in the direction away from the spinous process support 10. According to one embodiment, the projection of the spinous process support 10 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 201 of the lamina support 20 is smaller than the curvature 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 located on both sides of the third surface 203 are symmetrically distributed and are inward curved surfaces. The overall size of the lamina support 20 is smaller than that of the spinous process support 10.

[0050] According to one embodiment, the lamina support 20 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.

[0051] According to one embodiment, the spinous process support 10 may have a height H2 of 15 mm to 25 mm, a length L2 of 20 mm to 40 mm, and a width W2 of 10 mm to 20 mm.

[0052] Fig.12 The figure is a side view of an orthopedic support component in use according to one embodiment of the present application.

[0053] Fig.13It is a front view schematic diagram of an orthopedic support component in use according to one embodiment of the present application.

[0054] 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 laminas. 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 one embodiment, the lamina support 20 and the spinous process support 10 can be integrally formed.

[0055] According to one embodiment, the connection points of the surfaces of the orthopedic support component 1 are arc-shaped, which can better fit the biological anatomical structure.

[0056] 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 silicone rubber, TPU and other elastomers, and the vertebral plate support 20 can have a hydrophilic coating or adhesive sheet to prevent soft tissue adhesion. The selected materials have good biocompatibility. In some embodiments, the strap part can be fixed with a buckle.

[0057] 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 binding 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.

[0058] The above embodiments are only used to illustrate the present application, and are not intended to limit the present application. Ordinary technicians in the relevant technical field may 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 disclosed in the present application.
