Description

Technical Field

[0001] The present invention relates to the technical field of implant nail implantation, in particular to an auxiliary device for implant nail implantation. Background Art

[0002] Micro-implant anchorage screws are implanted in the alveolar bone of adjacent buccal and palatal tooth roots. During re-implantation, the pin should be minimized from contacting the tooth root. Therefore, the pin's placement position and angle must be carefully evaluated and measured before implantation. In current clinical practice, the surgeon's experience is used, combined with oral CBCT imaging to observe the implant site. The placement position and angle of the micro-implant anchorage screw are determined using the horizontal axis, the horizontal line along the adjacent tooth tips, and the vertical axis along the adjacent tooth at the implant site. The surgeon then uses the surgeon's experience to determine the placement position and angle within the patient's mouth. However, deviations in the position or angle of the pin during implantation can lead to root damage, root contact, reduced pin stability, or even pin loss, or pin entry into the maxillary sinus or nerve damage. Existing devices obstruct the surgeon's view due to the lips. Furthermore, during implantation, the angle of the pin body prevents fixation, leading to deviations in the device's entry angle, which in turn affects the accuracy and efficiency of the implant.

[0013] Preferably, the support frame is arc-shaped, and a flexible skin-friendly layer is provided on the surface of the support frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention fits the support frame in the device to the patient's external tooth socket and fixes the support frame at the same time. Then, according to the position of the lips, the flexible plate is rotated to rotate on the first universal ball. At this time, the flexible plate contacts the inner side of the patient's lips, and the telescopic rod and the support rod are used to support the patient's lips, so that the lips and the tooth socket are kept away, thereby making the device more convenient when implanting the nail body and preventing the lips from blocking the patient's tooth socket, thereby affecting the device's line of sight during the implantation process, further improving the convenience of the device during implantation.

[0016] 2. When the support frame is fixed, the slider is pulled to slide in the guide groove so that it moves to the position where it needs to be implanted. The movement of the slider in the guide groove allows the device to adapt to different positions. When the slider moves to the appropriate position, the second universal ball is rotated. At this time, the angle of the support mechanism changes with the second universal ball, so that the device can be changed as needed during implantation, making the device more accurate and multi-angled during implantation. When the second universal ball is adjusted, the screw rod is rotated. At this time, the screw rod squeezes the pressure piece so that the pressure piece cooperates with the support frame to fix the movable plate, and then fixes the slider. At the same time, as the screw rod moves, the screw rod squeezes the gasket on the slide rod, causing the slide rod to retract. At the same time, the friction block at one end of the slide rod squeezes the second universal ball, thereby ensuring the fixation of the second universal ball, thereby ensuring its adjusted angle. At this time, the slider and the second universal ball are both in a fixed state, which makes the device more convenient to implant and prevents shaking during the implantation process, thereby affecting the implantation accuracy of the device.

[0017] 3. When the device is adjusted, place the nail body between multiple support plates, and then rotate the rotating column. At this time, the gear drives the gear ring to rotate, and then changes the gap between the multiple expansion plates. At this time, the device can adjust the distance between the multiple expansion plates according to the diameter of the nail body, so that the device can support nails of different diameters, avoiding the situation where the nail body diameter is large or small, which causes the device to be unable to be fixed. Then rotate the nail body. At this time, the nail body gradually enters the patient's tooth socket, and the support plate gradually slides down. At this time, the support plate can initially guide the nail body so that the angle at which it enters the patient's tooth socket is the angle adjusted at the beginning, thereby further improving the implantation accuracy of the device. At the same time, when it enters a certain distance, the expansion plates are controlled to move away from each other. At this time, the nail body can be continuously rotated to make it completely implanted, and the device can be removed to complete the implantation of the device, further improving the implantation efficiency, convenience and accuracy of the device.

[0037] Preferably, the support frame 1 is arc-shaped, and a flexible skin-friendly layer is provided on the surface of the support frame 1, further increasing the comfort of the device when in use.

[0038] Working principle:

[0039] During operation, the support frame 1 in the device is fitted with the patient's outer tooth socket, and the support frame 1 is fixed at the same time. Then, according to the position of the lips, the flexible plate 10 is rotated to rotate on the first universal ball 8. At this time, the flexible plate 10 is in contact with the inner side of the patient's lips, and the telescopic rod 9 and the support rod 5 are used to support the patient's lips, so that the lips and the tooth socket are kept away, so that the device is more convenient when implanting the nail body, and the lips are prevented from blocking the patient's tooth socket, thereby affecting the device's line of sight during the implantation process, further improving the convenience of the device during implantation. After the support frame 1 is fixed, the slider 16 is pulled to slide in the guide groove 2 to move it to the required position. The position to be implanted, and the movement of the slider 16 in the guide groove 2 can make the device adapt to different positions. When the slider 16 moves to the appropriate position, the second universal ball 17 is rotated. At this time, the angle of the support mechanism 36 follows the second universal ball 17 to change, so that the device can be changed as needed during implantation, making the device more accurate and multi-angled during implantation. When the second universal ball 17 is adjusted, the screw rod 20 is rotated. At this time, the screw rod 20 squeezes the pressing piece 21, so that the pressing piece 21 cooperates with the support frame 1 to fix the movable plate 18, and then fixes the slider 16. At the same time, as the screw rod 20 moves, the screw rod 20 squeezes the gasket 26 on the slide rod 25, so that the slide rod 2 5 retracts, and at the same time, the friction block 28 at one end of the slide bar 25 squeezes the second universal ball 17, thereby ensuring the fixation of the second universal ball 17, thereby ensuring its adjustment angle. At this time, the slide bar 16 and the second universal ball 17 are both in a fixed state, which makes the device more convenient to implant and prevents shaking during the implantation process, thereby affecting the implantation accuracy of the device. When the device is adjusted, the nail body is placed between the multiple support plates 37, and then the rotating column 34 is rotated. At this time, the gear 35 drives the gear ring 31 to rotate, thereby changing the gap between the multiple expansion plates 32. At this time, the device can adjust the distance between the multiple expansion plates 32 according to the diameter of the nail body, so that the device It can support nail bodies of different diameters to avoid the situation where the nail body diameter is too large or too small, which makes the device unable to be fixed. Then the nail body is rotated, and the nail body gradually enters the patient's tooth socket. At the same time, the support plate 37 gradually slides down. At this time, the support plate 37 can initially guide the nail body so that the angle at which it enters the patient's tooth socket is the angle adjusted at the beginning, thereby further improving the implantation accuracy of the device. At the same time, when it enters a certain distance, the expansion plates 32 are controlled to move away from each other. At this time, the nail body can be continuously rotated to make it completely implanted, and the device can be removed, thereby completing the implantation of the device, further improving the implantation efficiency of the device as well as the convenience and accuracy of the implantation.
