In addition, in this embodiment, several channels are arranged along the radial direction perpendicular to the axial direction of the fixing member 6 . Such a structure is relatively simple and easy to manufacture. However, it is not limited to the above arrangement, and the radial channels can also be opposite to the fixing member 6 . The axial direction of the adhesive is set at an acute angle, so that the direction of injection of the adhesive can be adjusted, which is beneficial to the fluidity of the adhesive. Further, another preferred embodiment of the fixing member according to the present invention is shown in FIG. 8 . As shown in FIG. 8 , the straight handle portion 64 is arranged between the operation portion 61 and the threaded portion 63 , that is, the threaded portion 63 is arranged at the lower portion of the fixing member 6 . During the process of screwing the fixing member 6 into the teeth, a threaded surface will also be formed on the upper hole surface of the teeth. Therefore, when the adhesive is injected, the adhesive will form a coupling with the threaded surface of the upper part, so that the force on the teeth can be optimized compared to that the threaded part is arranged on the upper part, and it is convenient for the manual tool to extract the teeth. Meanwhile, in the present embodiment, the diameter of the connecting portion 62 is the same as the diameter of the straight shank portion 64, which makes the structure relatively simple. However, it is not limited to the above-mentioned setting method, and the diameter of the straight handle 64 can also be set to be larger than the diameter of the connecting portion 62 , preferably the diameters of the two are the same.

In addition, referring to Figs. 9-11, the present invention also proposes an operation method using the tooth extraction system tool, and in this embodiment, the preferred fixing member as described above is adopted, and it is foreseeable that there are also The fixing members of the other embodiments described above may be used.

The operation method mainly includes the following steps: Step 1, as shown in FIG. 9 , drill holes in the teeth 8 of the patient to be extracted, and conventional drilling tools can be used here. It should be noted that the diameter of the drilled hole here should be adapted to the diameter of the threaded portion 63 of the fixing member 6 .

Step 2, as shown in FIG. 10 , firstly install the fixing part 6 into the hand tool 1 . Specifically, by aligning the concave portion 68 on the operating portion of the fixing member 6 with the protruding portion 54 on the transmission member 5 in the hand tool 1, since both adopt the same arc-shaped structure, the fixing member can be smoothly moved 6 is inserted into the transmission member 5, and the driving force is transmitted by the form fit. Next, the fixing part 6 is placed on the hole opened by the tooth 8, and the operator operates the power device on the operating end of the hand tool 1, for example, turns on the start switch of the power device, thereby driving the transmission part 4 to rotate, thereby driving the transmission part 5 and The fixing part 6 is rotated to fix the fixing part 6 in the hole of the tooth 8 , and the final operating state is shown in FIG. 11 .

Step 3, as shown in FIG. 11, the fixing part 6 at this time has been screwed in place. At this time, the operator operates the pumping device at the operating end of the hand tool 1, for example, turns on the start switch of the pumping device, thereby passing the pumping device. The part 3 injects adhesive into the axial and radial channels of the fixing part 6 and, as shown in FIG. 11 , the adhesive is also delivered to the gap between the fixing part 6 and the hole. As described above, when the threaded portion 63 is provided at the lower part of the fixing member 6, since the threaded surface is already formed on the upper part of the hole, when the adhesive is injected, the adhesive will come into contact with the groove of the threaded surface. As a result, the force on the teeth can be optimized, so that the fastening force between the fixing part and the teeth is stronger. Moreover, the adhesive can also enter the lower space of the hole, which also increases the fastening force between the fixing member 6 and the teeth. Here, any existing adhesive can be used as the above-mentioned adhesive. When the adhesive is cured, the tooth and the fixing part 6 are integrated. Due to the limitation of processing time, UV resin is preferably used here. At this time, the UV resin is irradiated with ultraviolet rays to cure the UV resin, thereby integrating the teeth and the fixing member 6 .

Step 4, as shown in FIG. 11 , after the adhesive is cured, the teeth and the fixing part 6 are integrated. At this time, the tooth is extracted with the manual tool 1 . As mentioned above, since the opening 24 on the lower side of the housing 2 is further provided with several protrusions 22 toward the center, and the protrusions 22 have the same arc-shaped structure as the recessed portion 68 and the protrusion 54 , so First, when the fixing part 6 is inserted into the transmission part 5 , the projections 22 do not form a blocking effect on the fixing part 6 . After the fixing member 6 is inserted in place, the fixing member 6 can be rotated. At this time, the fixing member 6 can be manually operated, or a power device can be used to drive the fixing member 6 to rotate. Thereby, the protrusions 22 are dislocated from the recesses 68 on the fixing member 6, and the protrusions 22 cooperate with the lower side of the operation portion 61 of the fixing member 6, so that the teeth can be pulled out with the manual tool. As shown in FIG. 3 , the opening 24 on the lower side of the housing is provided with four protrusions 22 toward the center, but it is not limited to the above-mentioned arrangement, for example, the number of the protrusions can also be increased, thereby improving the hand tool Force. As previously mentioned, extraction of the tooth with the hand tool is achieved with the projections described above. However, it is not limited to the above-mentioned setting method. For example, the above-mentioned protrusions may not be provided. At this time, the manual tool only realizes the fastening of the fixing part and injecting the adhesive. After the adhesive is cured and the teeth and the fixing part are integrated, The tooth is then extracted using additional hand tools. Thereby, the tooth can be easily extracted while not harming the patient as much as possible.

The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although the present specification has been described in detail with reference to the above-mentioned embodiments, the present invention is not limited to the above-mentioned specific embodiments. Therefore, Any modification or equivalent replacement of the present invention; and all technical solutions and improvements that do not depart from the spirit and scope of the present invention are all included in the scope of the claims of the present invention.
