In order to prevent the blockage of the curved needle, the solid needle also comprises a solid needle for dredging the curved needle I, the curved needle II, the curved needle III and the curved needle IV, and the solid needle can be respectively nested with the front ends of the suction straight tube and the suction bent tube.

In order to dredge the minimum-sized curved needle I, the outer diameter of the solid needle is phi 0.3 mm.

In order to facilitate the holding without slipping, the holding pipe is an injection molding pipe.

The utility model discloses root canal therapy imbibition ware is through connecting strong the inhaling of armchair and form the negative pressure, through the bent needle, attract the pipe and hold the pipe with liquid and solid debris suction root canal, keep the root canal dry and guarantee visibility, supplementary root canal therapy, its beneficial effect is:

1. the curved needle can extend into the deep part of the oral cavity after the straight (curved) suction pipe and the holding pipe are lengthened, so that the auxiliary treatment can be conveniently carried out on the back teeth.

2. The suction straight tube and the suction bent tube can be used by dentists under different treatment environments to provide different treatment angles.

3. Since the posterior root canal is thinner and the outer diameter of the curved needle is smaller, the curved needle with different specifications and sizes can be used in different stages of the root canal treatment.

4. The suction straight (bent) tube is provided with a pressure relief hole, when the bent needle sucks the gum, the finger releases the pressure relief hole to relieve pressure, so that the gum can be prevented from being damaged by the suction force of the bent needle.
