In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] In this embodiment, combined with Figure 1-2 , a micro root canal auxiliary device is provided, including a rod 10, a clamping seat 1 and a nut 2, the clamping seat 1 is fixed to one end of the rod 10, and the end of the clamping seat 1 away from the rod 10 is provided with at least two clamping jaws 11 arranged at intervals in the circumferential direction, each clamping jaw 11 encloses a clamping space for accommodating one end of a root canal file 3, and a first inclined surface is provided on the outer side of the clamping jaw 11; a second inclined surface matching the first inclined surface is provided inside the nut 2, the nut 2 is sleeved outside each clamping jaw 11 and is threadedly connected to the clamping seat 1, and a through hole for the root canal file 3 to pass through is provided at the end of the nut 2; wherein, when the nut 2 and the clamping seat 1 are tightened, the second inclined surface abuts against the first inclined surface to drive each clamping jaw 11 to shrink toward the clamping space.

[0025] The root canal file 3 is needle-shaped, having a head end and a blade end. The cross-section of the blade end can be a regular polygon, a convex polygon or a concave polygon, etc., so that it is used for drilling holes. The head end is used to be clamped and fixed. In this solution, the nut 2 and the clamping seat 1 are threadedly matched and sleeved on the outside of each clamping jaw 11. The head end of the root canal file 3 can pass through the through hole of the nut 2 and enter the clamping space formed by each clamping jaw 11. Thereafter, by tightening the nut 2, the second inclined surface can be pressed against the first inclined surface, thereby squeezing the outer side of the clamping jaw 11, so that the clamping jaw 11 shrinks inward and the clamping space becomes narrower. Finally, each clamping jaw 11 can stably clamp the root canal file 3, and the clamping operation is quick and efficient.

[0026] Furthermore, the clamping jaw 11 includes a spring sheet 111 connected to the main body of the clamping seat 1 and a chuck 112 connected to the end of the spring sheet 111, and the second inclined surface is arranged on the outer side of the chuck 112. The arrangement of the spring sheet 111 can make the clamping jaw 11 more easily deformable, and the position change of the chuck 112 is more sensitive during the process of tightening or loosening the nut, so that the root canal file 3 is more easily clamped or loosened.

[0027] Furthermore, in the radial direction, the thickness of the spring sheet 111 is smaller than the maximum thickness of the chuck 112; in the circumferential direction, the width of the spring sheet 111 is smaller than the width of the chuck 112. Specifically, both sides of the spring sheet 111 are provided with notches, which may be semicircular, trapezoidal, C-shaped, etc. By setting the thickness and width of the spring sheet 111, the deformation ability of the spring sheet 111 can be made stronger, and the clamping force of the chuck 112 can be more concentrated on the root canal file 3, so that the clamping is more secure.

[0028] Furthermore, the clamping seat 1 has a clamping hole connected to the clamping space. The clamping hole can accommodate a portion of the head end of the root canal file 3, which is convenient for adjusting the extension length of the clamped root canal file 3 without adjusting the stroke when the nut 2 is tightened or loosened, so the clamping operation is simple and efficient.

[0029] Furthermore, the outer diameter of the clamping seat 1 is greater than or equal to the maximum outer diameter of the clamping jaws 11, and the nut 2 is threadedly connected to the clamping seat 1; the outer diameter of the clamping seat 1 is smaller than the outer diameter of the rod 10, and the end of the rod 10 is used to stop the nut 2. In this way, the nut 2 can be conveniently sleeved outside each clamping jaw 11 and threadedly connected to the clamping seat 1, and will be stopped by the end of the rod 10 during the tightening process to prevent over-clamping.

[0030] Furthermore, the clamping jaws 11 are arranged at equal angles around the central axis of the clamping seat 1, and the first inclined surface and the second inclined surface are both conical surfaces with the central axis of the clamping seat 1 as the axis. In this way, the clamping jaws 11 can apply force to the root canal file 3 more evenly, and the clamping is more stable and reliable.

[0031] In this embodiment, the inner side of each clamping jaw 11 is an arc surface, so the clamping space is a cylindrical space, which is adapted to the root canal file 3, and the clamping seat 1 is provided with four clamping jaws 11. In some embodiments, the clamping seat 1 can be provided with two, three, five, six, etc. clamping jaws 11, which can be adaptively set according to actual conditions.

[0032] In one embodiment, both ends of the rod 10 are provided with a clamping seat 1 and a nut 2. In this way, both ends of the rod 10 can be clamped by the clamping claws 11 on the clamping seat 1 to fix the root canal file 3.

[0033] Combination Figure 3 In one embodiment, the end of the rod 10 away from the clamping seat 1 can also be provided with a push rod 4 and a push cap 5 threadedly connected to the push rod 4, the push cap 5 has a receiving space for accommodating the head of the root canal file 3, and the end of the push cap 5 is provided with a through hole for the root canal file 3 to pass through; when the push cap 5 and the push rod 4 are tightened, the end of the push rod 4 is against the end of the head of the root canal file 3.

[0034] Specifically, a notch 51 is provided on the side of the abutting cap 5 to connect the through hole and the receiving space. The notch 51 is used for the head of the root canal file 3 to enter the receiving space from the side and for the file body of the root canal file 3 to enter the through hole of the abutting cap 5 from the side. During use, the head of the root canal file 3 can be directed toward the notch 51 and the receiving space, the file body of the root canal file 3 can be directed toward the notch 51 and the through hole of the abutting cap 5, and then the root canal file 3 can be squeezed into the abutting cap 5, so that the root canal file 3 is installed in the receiving space. After that, the abutting cap 5 is tightened, so that the end of the abutting rod 4 can abut the head of the root canal file 3. Finally, the abutting cap 5 and the abutting rod 4 jointly abut the head of the root canal file 3. In this way, on the one hand, one end of the rod 10 can efficiently fix the needle-shaped root canal file 3, and on the other hand, the other end of the rod 10 can fix the root canal file 3 with a head.

[0035] It should be understood that the clamping space formed by each clamping jaw 11 of the present solution can be adaptively adjusted according to actual conditions. For example, the size of the clamping space formed by each clamping jaw 11 can be adjusted to accommodate the head of the root canal file 3, so that the root canal file 3 with a head can also be clamped.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
