In the description of the present application, it should be noted that the terms "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings or orientations or positional relationships that the products of the application usually place when using, and are only used for convenience in describing the present application and simplifying the description, but do not indicate or imply that the devices or elements that are referred to must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present application. Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.
It should also be noted that, unless expressly stated or limited otherwise, the terms "disposed" and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
In the process of carrying out root canal therapy operation, need at first carry out the preforming and swing and wash the clearance to the root canal, the preforming is in order to provide accurate moulding effect, guarantees the workspace of follow-up processing, and root canal preparation shaping is mainly through root canal file high-speed rotation in the root canal, and the inner wall that the grinding root canal reaches. The swinging cleaning is to clean the original pathological tissues, bacteria and other substances in the root canal, usually, the root canal is continuously flushed by pressurizing, so that the lower part of the root canal is difficult to clean effectively. If positive pressure and negative pressure linkage mode is adopted for flushing, the complexity of the structure and the equipment cost are increased. The mode that can also adopt to change equipment and make the filing needle in the equipment vibrate in the root canal with ultrasonic frequency through acoustic current effect and cavitation effect, carries out effectual getting rid of to the bubble in the medicinal material that fills, but this kind of mode need carry out the change many times to equipment, and foretell process often need alternate the change and use each other according to the state of an illness needs in the root canal therapy, and frequent change treatment equipment for the operation is inconvenient, and the operation is inefficient.
Based on this, the present embodiment provides an endodontic instrument, fig. 1 is one of the structural schematic diagrams of an endodontic instrument provided in some embodiments of the present application, and as shown in fig. 1, the endodontic instrument provided in an embodiment of the present application includes a bending tool 10 and a root canal file 20 detachably connected to the bending tool 10, and further includes a driving module 30 in transmission connection with the root canal file 20, the driving module 30 includes a rotary driver 31 (not shown in fig. 1) and a vibration generator 32, the rotary driver 31 is configured to drive the root canal file 20 to axially rotate, and the vibration generator 32 is configured to drive the root canal file 20 to radially vibrate.
As shown in fig. 1, in the endodontic device provided in the present embodiment, the bending tool 10 is configured to be disposed on the handle member and to perform necessary wiring connection, and the rotary driver 31 and the vibration generator 32 in the driving module 30 are operated to control the operation of the rotary driver and the vibration generator, so that the root canal file 20 is configured to perform corresponding operation on the root canal. Wherein, rotary actuator 31 is used for driving root canal file 20 rotatory, and root canal file 20 head is most advanced for stretch into the root canal inside, when root canal file 20 is rotatory with certain speed rotation, the root canal inner wall of the contact of root canal file 20 lateral wall can form required shape through polishing of root canal file 20 promptly. Furthermore, during the root canal irrigation by injecting a solution such as sodium hypochlorite, etc., and during the irrigation of the root canal with a pasty filling material after irrigation, the rotation of the rotary drive 31 is required to drive the root canal file 20 to rotate, so as to achieve sufficient irrigation and irrigation. Generally, the pasty filling material is prepared by mixing medicament powder such as bioceramic or trioxygenic mineral polymer with water, air is mixed into the medicament powder to form bubbles which are difficult to avoid in the preparation process of the pasty filling material, when the pasty filling material is filled into a root canal, the bubbles need to be removed as much as possible, so that the medicament material can be tightly filled in the root canal as much as possible, in this case, while the root canal file 20 rotates, the vibration generator 32 is controlled to drive the root canal file 20 to vibrate at a preset frequency along the radial direction of the root canal file 20, the root canal file 20 rotates and combines with vibration, the activation of the medicament filling activity can be facilitated, and the bubbles can be discharged quickly and efficiently. Or can also swing the in-process that washes or root canal fill at the root canal and control vibration generator 32 drive root canal file 20 vibration alone to make root canal file 20's working method diversified, reduce the operation inconvenience that the equipment change caused in the root canal therapy operation, each step that can cooperate root canal therapy is required, the efficiency and the effect of effectual improvement root canal therapy.
