The limiting groove 13 is adapted to the hand handle 4. The size of the auxiliary limiting tube 12 is not smaller than the size of the drilling motor 3. An auxiliary limiting ring 18 is fixedly connected to the inner side wall of the main limiting tube 11. The inner diameter of the auxiliary limiting ring 18 is smaller than the size of the drill bit 10, and the size of the drilling motor 3 is larger than the inner diameter of the auxiliary limiting ring 18.

In use, the two fixing mechanisms 2 are respectively positioned at the tooth positions on both sides of the implant, with the teeth located between clamping side plate 1 20 and clamping side plate 22. By rotating the adjusting screw 24, the moving plate 21 is driven to slide on the limiting slide 23, thereby driving clamping side plate 1 20 and clamping side plate 22 to move closer to each other. The clamping side plate 1 20 and clamping side plate 22 are used to clamp the teeth on both sides of the implant, thereby fixing the positions of the two fixing mechanisms 2 and the position adjusting mechanism 1. The contact pads 25 are provided to prevent damage to the patient's teeth during fixation.

[0032] Working principle: In use, position adjustment mechanism 1 is placed above the drilling position, and the two fixing mechanisms 2 are placed on the outer sides of the teeth on both sides of the implant. By rotating the adjusting screw 24, the moving plate 21 is driven to slide on the limiting slide 23, which in turn drives clamping side plate 1 20 and clamping side plate 22 to move closer to each other. The clamping side plate 1 20 and clamping side plate 22 are used to clamp the teeth on both sides of the implant, thereby fixing the positions of the two fixing mechanisms 2 and the position adjustment mechanism 1. The drilling position is adjusted by using the position adjustment mechanism 1, and the position of the adjusting frame 7 is fixed by using the locking bolt 8. When drilling, select a suitable drill bit 10 and connect it to the output end of the drilling motor 3. Place the drill bit 10 above the drilling position by passing it through the auxiliary limiting ring 18 and the main limiting tube 11. At the same time, rotate the auxiliary limiting tube 12 to adjust the limiting groove 13 to the position of the hand lever 4. The hand lever 4 is located inside the limiting groove 13. The lower end face of the drilling motor 3 abuts against the upper end face of the auxiliary limiting ring 18. Turn on the drilling motor 3 and press down on the hand lever 4 to drive the drilling motor 3, auxiliary limiting tube 12, main limiting tube 11 and auxiliary plate 14 to move downward and compress the abutment spring 16. Under the action of the limiting slide rod 15, the drilling motor 3 and the drill bit 10 can only move in a direction perpendicular to the drilling position, thereby effectively avoiding the impact of the medical staff's hand tremors on the patient and ensuring the drilling quality. After drilling is completed, rotate the adjusting screw 24 to move the clamping side plate 1 20 and clamping side plate 22 away from each other, and the device can be removed.
