[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5The utility model provides a technical solution: a nail hole sealing device for pedicle screw removal after surgery, comprising: a patient spine body 1, and a buffer protection ring 7 arranged on the right side of the patient spine body 1, and a support cap 2 is arranged on the right side of the buffer protection ring 7, and further comprising:

[0026] A support rod 3 is installed in the middle of the left side of the support cap 2, and a first connecting tooth 4 is provided on the outside of the support rod 3, a plug 5 is provided on the left side of the support rod 3, and a buffer support pad 6 is provided on the left side of the plug 5, a second connecting tooth 8 is provided on the outside of the support cap 2, and an anti-slip component 9 is provided on the outside of the second connecting tooth 8, forming a complete nail hole sealing device.

[0027] like Figure 1 、 Figure 3 and Figure 5 As shown, the anti-slip component 9 includes an anti-slip cap 901 installed on the outside of the second connecting tooth 8, and an anti-slip plate 902 is provided on the left side of the anti-slip cap 901, and a connecting block 903 is provided on the left side of the anti-slip plate 902. The anti-slip cap 901 is threadedly connected to the second connecting tooth 8, and the connecting block 903 is relatively engaged with the anti-slip cap 901, and the connecting block 903 is arranged at equal intervals on the right side of the anti-slip plate 902. After completing the installation of the support cap 2, the anti-slip cap 901 is rotated to make the anti-slip cap 901 move to the left along the second connecting tooth 8. At this time, the anti-slip cap 901 pushes the anti-slip plate 902 to contact the patient's spinal body 1, and the anti-slip plate 902 improves the connection stability between the anti-slip cap 901 and the patient's spinal body 1, thereby preventing the device from loosening and falling off due to the patient's daily activities, thereby improving the safety of the device.

[0028] like Figure 1 、 Figure 2 and Figure 5 As shown, the first connecting teeth 4 are threadedly connected to the patient's spinal body 1, and the first connecting teeth 4 are evenly arranged on the outside of the support rod 3, and the support cap 2 and the buffer protection ring 7 are relatively engaged. During the rotation of the support cap 2 to the left, the support cap 2 cooperates with the patient's spinal body 1 to clamp the buffer protection ring 7 between the support cap 2 and the patient's spinal body 1. At this time, the extrusion force of the support cap 2 to the right is buffered by the buffer protection ring 7, thereby improving the connection stability between the support cap 2 and the patient's spinal body 1.

[0029] like Figure 1 、 Figure 2 and Figure 4As shown, an operating handle 10 is provided on the right side of the support cap 2, and a limiting block 11 is provided on the left side of the operating handle 10. The limiting block 11 is relatively engaged with the support cap 2, and the limiting block 11 is set at an equal angle on the left side of the operating handle 10. By installing the operating handle 10 on the right side of the support cap 2, the limiting block 11 is engaged with the support cap 2 and rotated at the same time, so that the operating handle 10 pushes the support cap 2 to rotate to the left. At this time, the first connecting tooth 4 is engaged with the patient's spinal body 1 to fix the support cap 2 and the support rod 3 to the right side of the patient's spinal body 1, and the operating handle 10 is taken out to the right side at the same time, thereby completing the blocking work of the patient's spinal body 1 and improving the use efficiency of the device.

[0030] Working principle: When using the nail hole sealing device for removing pedicle screws after surgery, first install the operating handle 10 on the right side of the support cap 2. At this time, the limit block 11 is engaged with the support cap 2 and rotated at the same time, so that the operating handle 10 pushes the support cap 2 to rotate to the left. At this time, the first connecting tooth 4 is engaged with the patient's spinal body 1 to connect the support cap 2 and the support rod 3 to the right side of the patient's spinal body 1. At the same time, the operating handle 10 is taken out to the right side, and the support cap 2 is fixed to the right side of the patient's spinal body 1. At the same time, in the process of the support cap 2 rotating to the left, the support cap 2 cooperates with the patient's spinal body 1 to clamp the buffer protection ring 7 between the support cap 2 and the patient's spinal body 1. At this time, the buffer protection ring 7 buffers the squeezing force of the support cap 2 to the right, thereby improving the connection stability of the support cap 2 and the patient's spinal body 1;

[0031] Finally, by rotating the anti-slip cap 901, the anti-slip cap 901 is displaced to the left along the second connecting tooth 8. At this time, the anti-slip cap 901 pushes the anti-slip plate 902 to contact the patient's spinal body 1. The anti-slip plate 902 improves the connection stability between the anti-slip cap 901 and the patient's spinal body 1, avoiding the device from loosening and falling off due to the patient's daily activities, and improving the safety of the device. This is the method of using the nail hole sealing device for pedicle screw removal after surgery.
