[0028] During the process of using the herringbone crest positioning device of the present utility model: First, fix the bracket 1 on the operating table, then horizontally rotate the connecting plate 3 on the mounting part 2 and slide the connecting plate 3 in the horizontal direction to adjust the position of the camera 5 in the horizontal direction, so as to move the camera 5 directly above the surgical incision; fix the connecting plate 3 through the mounting part 2 to extend the first connecting part 4, and the first connecting part 4 pushes the camera 5 downward to make the camera 5 gradually approach the surgical incision to adjust the distance between the camera 5 and the spinal structure. The camera 5 can acquire images of the spine, and the display 6 can display the spinal images. The size of the display 6 can be selected according to needs, so that the size of the spinal image displayed on the display 6 can be larger than the actual size of the spine. Doctors can determine the position of the herringbone crest vertex on the spine by referring to the larger-sized spinal image displayed on the display 6, and can more conveniently and accurately locate the herringbone crest vertex. After the bracket 1 is fixed on the operating table, the position of the camera 5 in the horizontal direction and the position of the camera 5 in the vertical direction can be flexibly adjusted, and it is more flexible when adjusting the position of the camera 5.

[0029] After the herringbone crest vertex is located, make a mark at the position of the herringbone crest vertex. After the marking is completed, shorten the first connecting part 4 to move the camera 5 upward by a certain distance, and then the pedicle screw can be inserted into the patient's spine through the herringbone crest vertex.

[0030] In this embodiment, the herringbone crest positioning device of the present utility model further includes a connecting rod 7, a spherical ball 8, a first locking bolt 9 and a laser pen 10. The upper end of the connecting rod 7 is fixedly connected to the connecting plate 3. The lower end of the connecting rod 7 is recessed upward to form a spherical socket 11. A first screw hole is formed on the connecting rod 7. One end of the first screw hole communicates with the spherical socket 11 and the other end communicates with the outer surface of the connecting rod 7. The spherical ball 8 is located in the spherical socket 11. The spherical ball 8 is matched with the spherical socket 11. The first locking bolt 9 is screwed into the first screw hole. The screwing end of the first locking bolt 9 is used to abut against the spherical ball 8. The laser pen 10 is fixedly arranged at the lower end of the spherical ball 8.

[0031] Rotate the first locking bolt 9 in the first screw hole to make the screwing end of the first locking bolt 9 disengage from the spherical ball 8, and the spherical ball 8 can rotate in the spherical socket 11. Rotate the first locking bolt 9 in the first screw hole to make the screwing end of the first locking bolt 9 abut against the spherical ball 8, and the spherical ball 8 can be fixed in the spherical socket 11. At this time, the spherical ball 8 cannot rotate in the spherical socket 11.

[0032] After the doctor determines the position of the sacral crest through the spinal image displayed on the display 6, the laser pointer 10 emits a red beam, and the sphere 8 is rotated within the ball socket 11 to adjust the orientation of the light-emitting end of the laser pointer 10 (please refer to Figure 4 ), and finally, the red beam emitted by the laser pointer 10 is irradiated onto the position on the spine corresponding to the vertex of the sacral crest. Then, the sphere 8 is fixed within the ball socket 11 by the first locking bolt 9. The position of the vertex of the sacral crest can be marked by the light of the laser pointer 10, which is convenient when marking the vertex of the sacral crest.

[0033] One way to fix the laser pointer 10 to the sphere 8 is as follows: A fixing sleeve 14 and a fourth locking bolt 15 are connected to the lower end of the sphere 8. The upper end of the laser pointer 10 is fitted with the inner cavity of the fixing sleeve 14. A third screw hole is formed on the fixing sleeve 14. One end of the third screw hole communicates with the inner cavity of the fixing sleeve 14, and the other end communicates with the outer surface of the fixing sleeve 14. The fourth locking bolt 15 is screwed into the third screw hole, and the screwing end of the fourth locking bolt 15 is used to abut against the laser pointer 10. Rotating the fourth locking bolt 15 within the third screw hole so that the screwing end of the fourth locking bolt 15 abuts against the laser pointer 10, the laser pointer 10 can be fixed within the fixing sleeve 14, and the laser pointer 10 can be fixed to the lower end of the sphere 8. Rotating the fourth locking bolt 15 within the third screw hole so that the screwing end of the fourth locking bolt 15 disengages from the laser pointer 10, the laser pointer 10 can be removed from the fixing sleeve 14, that is, the laser pointer 10 can be removed from the lower end of the sphere 8. With this structure, the laser pointer 10 can be detachably connected to the lower end of the sphere 8. When the battery of the laser pointer 10 is low, it is convenient to remove and replace the laser pointer 10. It can be understood that in other embodiments, the laser pointer 10 and the sphere 8 can also be connected in other ways, as long as the laser pointer 10 can be stably connected to the sphere 8.

[0034] In this embodiment, the sacral crest positioning device of the present invention further includes a second connecting portion 12, and the second connecting portion 12 is used to detachably and fixedly connect the first connecting portion 4 to the connecting plate 3.

[0035] The first connecting portion 4 is detachably connected to the connecting plate 3. After the positioning and marking of the vertex of the sacral crest are completed, the first connecting portion 4 can be detached from the connecting plate 3 (please refer to Figure 5 ), and during the process of implanting the pedicle screw into the spine through the vertex of the sacral crest, it can prevent the first connecting portion 4 from obstructing the action of implanting the pedicle screw into the spine.

[0036] In this embodiment, the first connecting part 4 includes an electric push rod 401 with an output shaft facing downward, and the electric push rod 401 can be a miniature coaxial telescopic electric push rod with a model of L50, and the camera 5 is fixedly arranged at the lower end of the electric push rod 401; the second connecting part 12 includes a first transverse plate 121 and a second locking bolt 122, the first transverse plate 121 is horizontally arranged, and the first transverse plate 121 is fixedly connected to the connecting plate 3, and a vertical side surface of the first transverse plate 121 is recessed inward to form a groove 123, the The groove 123 runs through the upper and lower side surfaces of the first cross plate 121, and the groove 123 cooperates with the upper end of the electric push rod 401. The two opposite side walls of the groove 123 are recessed to form arc grooves, and the two arc grooves are arranged opposite to each other. Both arc grooves are provided with threads, and the second locking bolt 122 cooperates with the two arc grooves. The second locking bolt 122 is screwed into the two arc grooves, and the screwed-in end of the second locking bolt 122 is used to resist the upper end of the electric push rod 401.

[0037] The upper end of the electric push rod 401 is placed in the groove 123, and the second locking bolt 122 is rotated in the two arc grooves so that the screwed-in end of the second locking bolt 122 abuts against the upper end of the electric push rod 401. The second locking bolt 122 can press and fix the electric push rod 401 in the groove 123. With this structure, the second connecting portion 12 can fix the electric push rod 401 on the connecting plate 3, and the second connecting portion 12 can fix the first connecting portion 4 on the connecting plate 3. The second locking bolt 122 is rotated in the two arc grooves, and the second locking bolt 122 is screwed out and completely separated from the first horizontal plate 121. At this time, the electric push rod 401 can be taken out from the groove 123, and the first connecting portion 4 can be removed from the connecting plate 3.

[0038] During installation of the electric push rod 401 on the connecting plate 3, the electric push rod 401 is pushed into the groove 123 in the horizontal direction, and then the electric push rod 401 is pressed and fixed in the groove 123 by the second locking bolt 122. During removal of the electric push rod 401 from the connecting plate 3, the second locking bolt 122 is disengaged from the first transverse plate 121, and then the electric push rod 401 is moved in the horizontal direction to be removed from the groove 123. During installation or removal of the electric push rod 401 from the connecting plate 3, the electric push rod 401 does not need to be moved vertically, which can reduce the possibility that the lower end of the electric push rod 401 touches the patient.

[0039] In this embodiment, the first connecting portion 4 further includes a limiting plate 402. The limiting plate 402 is fixedly provided at the upper end of the electric push rod 401, and the lower side surface of the limiting plate 402 supports on the first cross plate 121.

[0040] The limiting plate 402 can support on the first cross plate 121, which can reduce the possibility that the electric push rod 401 drops downward and hits the patient, and can improve the use safety of the human-ridge positioning device of the present utility model.

[0041] In this embodiment, the bracket 1 includes a second cross plate 101, a vertical plate 102, a third locking bolt 103 and a support rod 104. There are two second cross plates 101. The upper and lower ends of the vertical plate 102 are respectively fixedly connected to one end of the two second cross plates 101.

[0042] The process of fixedly installing the bracket 1 on the operating table is as follows: Make the opening of the "U"-shaped structure face the edge of the operating table horizontally, then move the bracket 1 so that the two second cross plates 101 are respectively located on the upper and lower sides of the operating table, and then rotate the third locking bolt 103 in the second screw hole so that the screwing end of the third locking bolt 103 abuts against the operating table, so that the edge of the operating table is clamped in the middle by one of the second cross plates 101 and the screwing end of the third locking bolt 103. At this time, the bracket 1 can be fixed on the operating table, and it is more convenient to fix the bracket 1 on the operating table.

[0043] In this embodiment, the installation part 2 includes a first plate body 201, a shaft rod 202, a second plate body 203 and a threaded sleeve 204.

[0044] Rotate the threaded sleeve 204 on the second plate body 203 to make the threaded sleeve 204 move upward. Then, the lower side of the threaded sleeve 204 disengages from the upper side of the connecting plate 3. At this time, the connecting plate 3 can be horizontally rotated between the first plate body 201 and the second plate body 203, and the connecting plate 3 can be slid horizontally to adjust the position of the camera 5 in the horizontal direction. During this process, the upper and lower end faces of the connecting plate 3 always abut against the first plate body 201 and the second plate body 203, so that the connecting plate 3 cannot tilt in the up and down direction. Rotate the threaded sleeve 204 on the second plate body 203 to make the threaded sleeve 204 move downward and abut against the upper side of the connecting plate 3, and the connecting plate 3 can be fixed, so that the connecting plate 3 cannot continue to rotate and move on the installation part 2, and the position of the camera 5 in the horizontal direction can be fixed.
