A limiting component is jointly provided on the sides where the two movable collar rings 36 are away from each other, and connecting bars 27 are hingedly installed on the tops of the two movable collar rings 36. An upper guiding ring 26 is jointly hingedly installed on the tops of the two connecting bars 27.

Limiting blocks 13 are slidably connected to the inner cavities of the two limiting grooves 12. The opposite sides of the two limiting blocks 13 are respectively fixedly connected to the outer walls of the corresponding first rack bars 11. Through the cooperation of the limiting block 13 and the limiting groove 12, when the first rack bar 11 slides, the limiting block 13 can be driven to move in an arc inside the limiting groove 12, realizing the limitation of the movement track of the first rack bar 11 and improving the stability performance.

By means of the setting of the fixed seat 17, the first motor 15 is fixed to the bottom of the arc-shaped plate 8, further improving the stability performance of the first motor 15 during subsequent operation.

[0034] Please refer to Figure 6 , Figure 7 and Figure 8, the limiting component includes two limiting collar rings 35, the two limiting collar rings 35 are respectively sleeved and movably installed on the outer sides of the corresponding cross bars 38, and vertical blocks 34 are fixedly connected to the bottoms of the two limiting collar rings 35. Lower cross grooves 30 are respectively opened at the positions close to the left and right sides of the bottom of the cross frame 23, and second motors 31 are fixedly connected to the left and right sides of the cross frame 23. One ends of the two second motors 31 are fixedly connected with screw rods 32. One end of the screw rod 32 penetrates through the outer side of the cross frame 23 and is rotationally connected to the outer side of the cross frame 23 and the inner wall of the lower cross groove 30. A threaded sleeve 33 is threadedly connected to the outer side of the screw rod 32. A through groove 29 is opened between the lower cross groove 30 and the upper cross groove 28. The bottoms of the two vertical blocks 34 respectively penetrate through the corresponding through grooves 29 and are fixedly connected to the tops of the corresponding threaded sleeves 33. By driving the two second motors 31 to drive the screw rods 32 to rotate respectively, the two screw rods 32 drive the corresponding threaded sleeves 33 to move respectively. The threaded sleeve 33 drives the vertical block 34 to slide inside the through groove 29. At the same time, the vertical block 34 drives the upper limiting collar ring 35 to slide on the outer side of the cross bar 38. After the limiting collar ring 35 slides to a suitable position, the second motor 31 is turned off, which can block the movable collar ring 36 when the upper guiding ring 26 moves downward subsequently, realize the limitation of the moving distance of the upper guiding ring 26, and further realize the limitation of the puncture depth of the puncture device.

[0035] Working principle: When this application is in use, first, the mobile frame 1 is used to move the overall equipment system to a suitable position. Then, with the cooperation of the multi-functional perfusion pump 3, the general-purpose power shaving system 4, the multi-functional high-frequency system 5, the light source system 6, the minimally invasive spinal navigation system 7, and the display 40, the surgical position of the patient's cervical vertebra is accurately located and marked. Then, the puncture depth is limited according to the actual situation of the patient. At this time, two second motors 31 can be synchronously driven, so that the two second motors 31 drive the corresponding screws 32 to rotate respectively. The screws 32 drive the threaded sleeves 33 to move, and the threaded sleeves 33 drive the limit collar 35 on the vertical block 34 to move. After the limit collar 35 moves to a suitable position, the second motor 31 is turned off. At this time, the horizontal angle and vertical angle of the upper guide ring 26, the guide hole 39, and the lower guide ring 25 need to be adjusted. The first motor 15 can be driven first, so that the first motor 15 synchronously drives the front and rear rotating rods 16 to rotate. The two rotating rods 16 drive the corresponding first gears 14 to rotate respectively. The two first gears 14 drive the corresponding first racks 11 to slide respectively. The first racks 11 drive the corresponding arc-shaped frames 9 to slide. The two arc-shaped frames 9 jointly drive the angle deflection of the components such as the upper guide ring 26 and the lower guide ring 25 on the two side shells 18, realizing the preliminary adjustment of the guiding angle of the puncture device. After the components such as the upper guide ring 26 and the lower guide ring 25 are adjusted, the first motor 15 is turned off and locked. Then, the longitudinal angle of the components such as the upper guide ring 26 and the lower guide ring 25 is adjusted. The two electric push rods 19 can be synchronously driven, so that the two electric push rods 19 respectively push the corresponding second racks 20 to move. The two second racks 20 respectively push the corresponding second gears 21 to rotate. The two second gears 21 respectively drive the corresponding round shafts 22 to rotate. The two round shafts 22 jointly drive the cross frame 23 to rotate. The cross frame 23 drives the components such as the upper guide ring 26 and the lower guide ring 25 to deflect longitudinally. After the adjustment, the two electric push rods 19 are turned off, and the self-locking of the components such as the cross frame 23 is realized by the cooperation of the second rack 20 and the second gear 21. When the puncture device passes through the upper guide ring 26, the guide hole 39, and the lower guide ring 25 for puncture surgery, the puncture device will press down on the upper guide ring 26, so that the upper guide ring 26 pushes the two outer connecting bars 27 to move. The two connecting bars 27 respectively push the corresponding movable collar 36 to move outside the cross bar 38. At the same time, the movable collar 36 stretches the corresponding spring 37. After the movable collar 36 moves to fit with the corresponding limit collar 35, the limit collar 35 is used to limit the movable collar 36, further realizing the limitation of the puncture device and the limitation of the puncture depth, improving the safety performance of the subsequent surgery.
