The driving member 23 drives the output shaft 22 and the needle 1 to rotate for a preset duration and then automatically stops. If the needle 1 does not rotate to the target position when it stops, the doctor can press the control unit again to make the driving member 23 continue to drive the output shaft 22 and the needle 1 to rotate for a preset duration to continue adjusting the angle of the needle 1. In this way, the doctor can repeatedly press the control unit 23 until the needle 1 rotates to the target position. In this embodiment, when the control unit 25 is pressed once, the rotation duration and the rotation angle of the needle 1 are not limited and can be set according to actual needs.

[0032] In this embodiment, when adjusting the orientation angle of the needle 1, the needle 1 can rotate arbitrarily by 360° around the central axis of the output shaft 22; after the orientation angle of the needle 1 is adjusted, the control unit 25 controls the needle 1 to perform a small-angle reciprocating swing to perform sonic irrigation on the root canal.

[0037] In this embodiment, the shape of the output shaft 22 is not limited. The output shaft 22 can be columnar, plate-shaped or other shapes.

[0038] In this embodiment, the connection method between the needle 1 and the output shaft 22 is not limited, and the needle 1 can be integrally formed with the output shaft 22 or detachably connected. In a preferred embodiment, a needle connection portion 221 is provided on the side of the output shaft 22 close to the needle 1, and the needle connection portion 221 protrudes out of the handle housing 21, and the needle 1 is detachably fixed on the needle connection portion 221. In this embodiment, the needle 1 is used as a consumable part, and the needle 1 is detachably fixed on the needle connection portion 221, which is convenient for removing the needle 1 for replacement; in addition, the needle connection portion 221 protrudes out of the handle housing 21, which is convenient for loading and unloading the needle 1 from the outside of the handle housing 21.

[0039] In one embodiment, please refer to Figure 1 The needle connection part 221 is a straight structure, the needle 1 is a curved needle 1, and the needle 1 has a straight section 11 and an arc section 12 connected to each other, and the straight section 11 is fixedly connected to the needle connection part 221. In this embodiment, the curved needle 1 can better adapt to the root canal shape, ensuring that the needle 1 can reach every corner of the root canal during cleaning and disinfection. In addition, the curved needle 1 can conform to the bending direction of the root canal, reduce resistance, and improve the smoothness of the operation.

[0040] In this embodiment, the inner tube wall of the straight section 11 of the needle 1 is provided with an internal thread, and the outer wall surface of the needle connecting part 221 is provided with an external thread matching the internal thread, so that the straight section 11 of the needle 1 and the needle connecting part 221 can be threadedly connected.

The control unit 25 and the gripping portion are staggered to prevent the doctor from accidentally touching the control unit 25 when grasping the handle structure 100 of the sonic root canal irrigator.

[0044] In another embodiment, the main circuit board 24 has a standby mode and an operating mode. When the sonic root canal irrigator handle structure 100 is in the standby mode, the driving member 23 can be activated by pressing the control unit 25, so that the output shaft 22 and the needle 1 slowly rotate to adjust the angular position of the needle 1; when the sonic root canal irrigator handle structure 100 is in the operating mode, pressing the control unit 25 cannot adjust the angular position of the needle 1; thus, it is possible to prevent the doctor from accidentally touching the control unit 25 during the operation of the sonic root canal irrigator handle structure 100, causing the needle 1 to rotate accidentally and affecting the safety of the operation.

[0045] Furthermore, the handle body 2 further includes a display structure 26, which is fixed on the handle housing 21.

[0046] In one embodiment, please refer to Figure 1 , the handle body 2 further includes an angle sensor assembly. The angle sensor assembly is disposed adjacent to the driving member 23 and is electrically connected to the main circuit board 24. The angle sensor assembly is used to directly or indirectly detect the rotation angle of the needle 1 and reflect the detected rotation angle on the display screen, so as to more accurately identify the rotation angle of the irrigation needle 1 and improve the accuracy of adjusting the rotation angle of the needle 1.

[0047] Furthermore, the angle sensor assembly includes a sensor 27 and a sensor circuit board (not shown in the figure).

The sensor circuit board is electrically connected to the main circuit board 24, the display structure 26 is signal-connected to the sensor circuit board, and the display structure 26 is electrically connected to the main circuit board 24. In this embodiment, the specific type of the angle sensor 27 is not limited, and the angle sensor 27 can be a Hall sensor, a resolver, an encoder, etc.

[0048] In a specific embodiment, the angle sensor 27 is a Hall sensor, and the driving member 23 is a DC motor. The DC motor is provided with a stator and a rotor. A magnet is provided on the stator. When the stator is energized, a magnetic field can be generated. The rotor can rotate relative to the stator under the action of the magnetic field. The output shaft 22 is fixedly connected to the rotor. When the rotor rotates, it can drive the output shaft 22 and the needle 1 to rotate synchronously. When the rotor rotates, the magnetic field will change. The Hall sensor can detect the change in the magnetic field and convert this change into a measurable electrical signal.
