Referring to fig. 1 to 3, the anchorage nail auxiliary implantation device in the embodiment of the invention comprises a positioning guide plate 1, an implantation guide plate 2 and a depth-limiting snap ring 5. Wherein, location baffle 1 is used for assisting the doctor to squeeze into the predrilled hole in the relevant position, implants baffle 2 and is used for injecing anchorage nail and implants patient's gum with the set angle in, and limit for depth snap ring 3 is used for controlling the intraosseous degree of depth of anchorage nail.
The positioning guide 1 includes a first retaining portion 11 and a positioning portion 12, and the first retaining portion 11 is connected to the positioning portion 12. Wherein the first retention portion 11 is either for retention by the patient's maxillomandibular occlusion or for retention by the surgeon's hand in the event that the patient fails to engage. One side of the positioning part 12 is attached to the gum surface of the patient, and in order to improve the attaching accuracy, the positioning part 12 capable of being matched with the gum contour of the corresponding position of the patient can be manufactured after the gum contour of the corresponding position of the patient is obtained through three-dimensional scanning. The positioning portion 12 is provided with a positioning hole 121 and a positioning tube 122, the positioning hole 121 is used for assisting in puncturing gingiva at a corresponding position of a patient and drilling a pre-drilled hole in cortical bone, so that slippage of a subsequent anchorage nail caused by over-inclination of an implantation angle or fracture of the anchorage nail caused by hard bone at an implantation position can be avoided, and position reference is provided for the subsequent anchorage nail. Specifically, the diameter of the positioning hole 121 is tapered from large to small, which facilitates control of the drilling depth of the drill. One end of the positioning tube 122 protrudes outwards, and the other end of the positioning tube 122 communicates with the positioning hole 121 for guiding the drill to drill into the gum of the patient.
The implant guide 2 includes a second retaining portion 21 and a guide portion 22, and the second retaining portion 21 is connected to the guide portion 22. Wherein the second retention portion 21 is adapted to be retained by both the patient's maxillomandibular engagement and by the surgeon's hand in the event that the patient is unable to engage. One side of the guiding portion 22 is attached to the gum surface of the patient, and in order to improve the attaching accuracy, the guiding portion 22 can be manufactured to be matched with the gum contour of the corresponding position of the patient after the gum contour is obtained through three-dimensional scanning. The guide part 22 is provided with a guide hole 221 and a guide tube 222, the position of the guide hole 221 corresponds to the position of the positioning hole 121, and a first end of the guide tube 222 protrudes outwards and is used for guiding the anchorage nail to enter; the second end of the guide tube 222 communicates to the guide hole 221, thereby guiding the anchorage pin to the guide hole 221. The guide tube 222 defines the implantation angle of the anchorage pin, thereby avoiding instances where the anchorage pin may damage the patient's root due to angular misalignment when implanted. An observation window 223 is reserved on the side surface of the guide tube 222 and close to the guide hole, so that a doctor can conveniently observe the implantation condition of the anchorage nail in real time.

The implanter refers to an auxiliary tool for implanting anchorage nails, such as an anchorage nail long handle tool head or an anchorage nail bending machine head, and also includes other special implantation tools for implanting anchorage nails. When one end of the depth-limiting snap ring 5 abuts against the first end of the guide tube 222, the anchorage nail implantation is stopped, thereby limiting the implantation depth of the anchorage nail.
It is easy to understand that the anchorage pin can be implanted directly by using the implantation guide 2 and the depth-limiting snap ring 5 without using the positioning guide 1 in the implantation area with thin cortical bone or the implantation area with a small implantation inclination angle of the anchorage pin.
Further, in some embodiments, the first retention portion 11 is detachably connected to the positioning portion 12, and the second retention portion 21 is detachably connected to the implantation portion 22, and the connection manner may be a pin connection manner or a snap connection manner, or other detachable connection manners capable of achieving the same effect, so that the portions may be separated from each other, and the positioning portion 12 and the implantation portion 22 may share one retention portion, thereby reducing the production cost. In the present embodiment, the first fixing portion 11 and the positioning portion 12 are formed as an integrated structure, and the second fixing portion 21 and the implanting portion 22 are formed as an integrated structure, thereby facilitating the integrated fabrication of the positioning guide plate 1 and the implanting guide plate 2 which can be attached to the gingival and maxillofacial surfaces of the patient, and improving the accuracy of the attaching degree and the implantation position of the anchorage pins.
Further, referring to the upper and lower direction of fig. 4, the upper side of the first retention portion 11 and the upper side of the second retention portion 21 are both provided with the profiling structures 3 matched with the occlusal surface of the patient's teeth, so that the positioning guide plate 1 and the implantation guide plate 2 can be more fit with the occlusal surface of the patient's teeth, and the looseness does not occur, thereby facilitating the determination of the implantation position of the anchorage pins.
Further, referring to the top-bottom orientation of fig. 4, both the underside of the first retaining portion 11 and the underside of the second retaining portion 21 are provided with convex striations 4 for increased friction. When the patient's upper and lower jaws engage with the first retaining portion 11 or the second retaining portion 21, the lower side of the first retaining portion 11 or the second retaining portion 21 may be filled with a filler such as a sterile cotton ball to increase the height of the engagement, improving the comfort of the patient when engaged.
Further, the positioning guide 1 further comprises a first supporting rod 13, and two ends of the first supporting rod 13 are respectively connected to the first fixing portion 11 and the positioning tube 122, so as to provide additional support for the positioning tube 122 and enhance the structural strength of the positioning guide 1.
