Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the following detailed description, reference can be made to the accompanying drawings, which form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Specific embodiments of the present application are described in sufficient detail below to enable those skilled in the art to implement the technical solutions of the present application. It should be understood that other embodiments may also be utilized, or structural, logical, or electrical changes may be made to the embodiments of the present application.

[0023] The technical solution of this application will be further illustrated below through specific implementation methods. Those skilled in the art should understand that the following description is merely for the convenience of understanding the technical solution of this application and should not be used to limit the scope of protection of this application.

[0024] This application provides an orthopedic support component and an orthopedic support system. By simultaneously placing an elastic component between the vertebral lamina and the spinous process for support, and fixing the spinous process support component to the pedicle with bone screws, the lumbar spine structure can achieve stable and controllable movement, thereby restoring intervertebral height and decompression.

[0025] Since the spinous process is a sheet-like bone that connects to the spine at one end and extends away from the spine at the other end, for the convenience of subsequent description, the plane in which the spinous process extends and the plane perpendicular to it can be defined.

[0026] Figure 1 This is a side view of an orthopedic support according to an embodiment of this application.

[0027] Figure 2 According to Figure 1 A front view schematic diagram of the orthopedic support component in the embodiment.

[0028] As shown in the figure, the orthopedic support includes a vertebral laminar support 10 and a spinous process support 20. According to one embodiment, the vertebral laminar support 10 and the spinous process support 20 can be integrally formed. According to one embodiment, the orthopedic support can be made of an elastic material with good resilience. According to one embodiment, the projection of the spinous process support 20 onto a plane perpendicular to the spinous process extension plane is approximately an inverted trapezoid, and the projected length of the third surface 201 of the spinous process support 20 is greater than the projected length of the fourth surface 202. The third surface or upper surface 201 is used to support the first spinous process, and the fourth surface or lower surface 202 is used to support the second spinous process. According to one embodiment, the third surface 201 and the fourth surface 202 of the spinous process support 20 have opposing curved surfaces, wherein the curvature of the third surface 201 can be greater than the curvature of the fourth surface 202.

[0029] According to one embodiment, the spinous process support 20 can be solid or partially hollow. When the spinous process support 20 is hollow, it can be compressed to a certain extent during the insertion of the orthopedic support between the spinous processes, making installation easier.

[0030] According to one embodiment, the spinous process support 20 may include a first channel 203 and a second channel 204 for the passage of the bone screw. According to one embodiment, the cross-section of the channel may be circular or square (not shown); according to another embodiment, the cross-sectional shape of the channel is determined by the shape of the bone screw.

[0031] According to one embodiment, the diameter of the channel through which the bone screw passes can range from 2mm to 8mm, and bone screws of different diameters can be selected according to different requirements.

[0032] According to one embodiment, the first channel 203 and the second channel 204 are not parallel, and the extensions of the first channel 203 and the second channel 204 intersect in a direction away from the pedicle. The angle of intersection is determined by the location where the pedicle needs to be nailed and the relative position of the orthopedic support to the pedicle.

[0033] According to one embodiment, such as Figure 1 As shown, the spinous process support 20 may further include a first surface 205 away from the lamina support 10 and a second surface 206 adjacent to and connected to the lamina support 10. According to one embodiment, the first channel 203 and the second channel 204 open onto the first surface 205. According to one embodiment, the line connecting the openings of the first channel 203 and the second channel 204 may be the midline of the first surface 205, but it can also be positioned at other locations as needed. According to one embodiment, the openings of the first channel 203 and the second channel 204 may be close to the left and right edges of the first surface 205, but the distance between the opening and the edge can also be determined as needed. According to one embodiment, the distances from the openings of the first channel 203 and the second channel 204 to the third surface 201 or the fourth surface 202 may be the same or different, depending on the location of the pedicle screw to be inserted.

[0034] According to one embodiment, the spinous process support 20 may further include two side surfaces, a fifth surface 207 and a sixth surface 208, that gradually converge from top to bottom. According to one embodiment, a first channel 203 of the spinous process support 20 may open onto the fifth surface 207, and a second channel 204 may open onto the sixth surface 208. According to one embodiment, the opening of the first channel 203 on the fifth surface 207 may be elliptical or of other shape. According to one embodiment, the first channel 203 and the second channel 204 may be symmetrically distributed relative to a plane extending along the spinous process, allowing the orthopedic support to be fixed at the pedicle using bone screws.

[0035] Figure 3 This is a rear view schematic diagram of an orthopedic support according to an embodiment of this application.

[0036] Figure 4 According to Figure 3 A top view of the orthopedic support component in the embodiment.

[0037] As shown in the figure, the lamina support 10 is connected to the second surface 206 of the spinous process support 20. It protrudes in a direction away from the spinous process support 20, and its projection onto the spinous process support 20 on the vertical plane of the spinous process extension surface is a fan ring. The first surface 101 of the lamina support 10 has a smaller arc than the second surface 102. The third surface 103 that contacts the spine is a plane. The fourth surface 104 and the fifth surface 105 of the lamina support 10 are symmetrically distributed and are inwardly curved surfaces.

[0038] According to one embodiment, the width W1 of the vertebral plate support 10 can be 2mm-6mm, the height H1 can be 5mm-12mm, and the length L1 can be 10mm-17mm.

[0039] According to one embodiment, the height H2 of the spinous process support 20 can be 15mm-25mm, the length L2 can be 20mm-40mm, and the width W2 can be 10mm-20mm. The overall size of the lamina support 10 is smaller than that of the spinous process support 20.

[0040] Figure 5 This is a side view of an orthopedic support system in use according to an embodiment of this application.

[0041] Figure 6 According to Figure 5 A frontal view of the orthopedic support system in use according to the embodiment.

[0042] The lamina support 10 is placed in the gap between the first lamina 301 and the second lamina 302 to open up the two lamina. At this time, the third surface 201 of the spinous process support 20 abuts against the first spinous process 303, and the fourth surface 202 abuts against the second spinous process 304. The first bone nail 305 and the second bone nail 306 are passed through the channel structure on the spinous process support 20 and nailed into the corresponding position of the pedicle, thereby fixing the entire orthopedic support and preventing the orthopedic support from loosening and falling off.

[0043] According to one embodiment, the joints of each surface of the orthopedic support are arc-shaped, which can fit well with the biological anatomical structure.

[0044] To prevent damage to the spine and surrounding tissues while ensuring the rigidity of the support system, the orthopedic support and fixation screws can be made of polymeric materials, such as silicone rubber, TPU, and other elastomers. The vertebral laminar support 10 can have a hydrophilic coating or adhesive pad to prevent soft tissue adhesion. All selected materials possess good biocompatibility. In some embodiments, the fixation screws can be made of metal.

[0045] The orthopedic support component and orthopedic support system of this application simultaneously support the vertebral lamina and spinous process, and fix the elastic body between the spinous processes at a set angle using bone screws. This can restore the physiological curvature of the spine, relieve nerve root compression pain, and at the same time, achieve stability and controllability of lumbar spine 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.

[0046] The above embodiments are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art can make various changes and modifications without departing from the scope of this application. Therefore, all equivalent technical solutions should also fall within the scope of this application.
