Embodiment 1
[0043] Example 1 3D printed cervical pedicle screw-guided implant plate structure
[0044]A 3D-printed cervical pedicle screw-guided implantation plate, comprising a solid guide plate 1, the size of which can cover one cervical lamina; 1 is also provided with a spinous process hole 3; the spinous process hole 3 is located on one side of the guide plate 1, and the guide screw track 2 is set on the other side of the guide plate 1, and the direction of the guide screw track 2 is consistent with the direction of the pedicle screw screw entry track , through the guide screw channel 2, the screw can accurately enter the pedicle. The upper part of the guide plate 1 is a flat surface 11, and the curved surface 12 at the bottom of the guide plate 1 is in the same direction as the operation vertebral plate. One side of the upper plane 11 of the guide plate 1 extends to the exit of the guide nail channel 2, and then extends outward for 5 mm. From one side to the other side of the spino...
Embodiment 2
[0046] Example 2 3D printed structure of cervical pedicle screw-guided implant plate
[0047] A 3D-printed cervical pedicle screw-guided implant plate, including a solid guide plate 1, the size of which can cover one cervical lamina; two pedicle screw guide channels 2 arranged on the guide plate 1, and the guide plate 1 is also provided with a spinous process hole 3; the spinous process hole 3 is located in the center of the guide plate 1, and two guide screw tracks 2 are arranged on both sides of the guide plate 1. The direction of the guide screw track 2 is consistent with the direction of the pedicle screw screw entry track. Through the guide screw channel 2, the screw can accurately enter the pedicle. The upper part of the guide plate 1 is a plane 11, and the curved surface 12 at the bottom of the guide plate 1 can be in the same direction as the surgical lamina; After the exit, extend 4mm outward. The shape of the spinous process hole 3 is consistent with that of the sp...
