[0032] refer to Figure 3 and Figure 4 As shown, the hole-introducing needle 32 includes a first connecting portion 321 close to one end of the handle 31, a hole-introducing portion 323 away from the handle 31, and a first main body 322 connecting the first connecting portion 321 and the hole-introducing portion 323. The first connecting portion 321 is provided with a circumferential clamping groove 3211 corresponding to the circumferential clamping portion 313 and an axial clamping groove (not shown) corresponding to the axial clamping portion. The axial position limitation of the hole-introducing needle 32 is achieved by the cooperation between the circumferential clamping portion 313 and the circumferential clamping groove 3211, and the circumferential position limitation of the hole-introducing needle 32 is achieved by the cooperation between the axial clamping portion and the axial clamping groove.
[0033] The guide hole portion 323 is a conical structure, which is convenient for the doctor to prepare the guide hole on the alveolar bone 20 .
[0034] Combination Figure 3 As shown, a first curved portion 3221 is provided on the first body 322, and the first curved portion 3221 is located in the range of 1 / 2 to 1 / 5 of the first body 322 close to the lead hole portion 323. The first curved portion 3221 forms an angle α between the axis of the lead hole portion 323 and the axis of the handle 31, and the angle α is in the range of 20° to 60°, so that the doctor can control the handle 31 to make the lead hole portion 323 perpendicular to the alveolar bone 20 when implanting the posterior molar. In this embodiment, the angle α is 30°. In some other embodiments, the angle α can also be 25°, 35°, 40° or 50°.

The axial position limitation of the elbow rod 33 is achieved by the cooperation between the circumferential clamping portion 313 and the circumferential clamping groove 3211, and the circumferential position limitation of the elbow rod 33 is achieved by the cooperation between the axial clamping portion and the axial clamping groove.
[0036] The nail removal portion 333 is generally in a flat structure, which makes it convenient for the doctor to insert the nail removal portion 333 between the alveolar bone 20 and the nail cap 11 of the positioning nail 10 .
[0037] Combination Figure 5 As shown, the end edge of the nail removal portion 333 is also provided with an opening 334. When the doctor inserts the nail removal portion 333 between the alveolar bone 20 and the nail cap 11 of the positioning nail 10, the nail rod 12 of the positioning nail 10 is located in the opening 334, thereby increasing the contact area between the nail cap 11 and the nail removal portion 333, so as to facilitate the removal of the positioning nail 10. In this embodiment, the edge of the opening 334 is composed of an arc segment 3341 for contacting the nail rod 12 and a straight segment 3341 for increasing the insertion degree. The diameter of the arc segment 3341 is 1.5 mm, and the distance between the two straight segments 3341 is the same as the diameter length of the arc segment 3341. In some other embodiments, the diameter of the arc segment 3341 is the same as the length of the nail rod 12.
[0038] Combination Figure 3 As shown, the second body 332 is provided with a second curved portion 3221, and the second curved portion 3221 is located in the range of 1 / 2 to 1 / 5 of the second body 332 close to the nail removal portion 333. The second curved portion 3221 forms an angle β between the axis of the nail removal portion 333 and the axis of the handle 31, and the angle of the angle β is in the range of 120° to 150°, so that the doctor can pull out the positioning nail 10 from the alveolar bone 20.
