Description

Technical Field

[0001] The utility model relates to the technical field of root canal irrigators, and more specifically, to a root canal irrigator needle structure. Background Art

[0002] The root canal irrigator activates the liquid in the root canal by transmitting high-frequency oscillations to the irrigating needle, causing the liquid to produce a large number of tiny bubbles, forming a cavitation effect and ultrasonic flow. The instantaneous high pressure generated by the continuous tiny bubbles destroys the smear layer and biofilm, thereby achieving the effect of cleaning root canal stains and debris. During the use of existing irrigating needles, since the end cross-section of the needle is mostly circular, it is inconvenient to deliver the filling paste, resulting in insufficient and compact filling of the paste, and difficulty in removing pulp calcifications in the root canal, affecting the thoroughness of root canal irrigating and decontamination. In view of this, we propose a root canal irrigating needle structure to solve the above problems. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a root canal flushing needle structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a root canal flushing needle structure, comprising a flushing needle, a needle-mounting column and a transmission seat, wherein the flushing needle is fixedly mounted on one end of the needle-mounting column, the cross-sectional shape of the end of the flushing needle is triangular, and each corner of the end of the flushing needle is provided with an arc-shaped edge, the needle-mounting column is fixedly connected to one end of the transmission seat through a front connecting portion, and a scale assembly is fixedly provided on the outside of the needle-mounting column.

[0005] As a preferred technical solution of the present invention, the cross-sectional shape of the needle loading column is circular, and the diameter of the needle loading column is 0.4 mm-0.6 mm.

[0006] As a preferred technical solution of the present invention, the scale assembly includes three scale markings distributed at equal intervals, and the distance between two adjacent scale markings is 1 mm.

[0007] By setting it in this way, the purpose of serving as a scale mark is achieved.

[0008] As a preferred technical solution of the present invention, it further includes a protective cover, and the transmission seat is fixedly connected to the outer side of the protective cover through a rear connecting part.

[0009] By setting up a protective cover, the protective cover can be used to shield and protect the joint between the vibration end and the installation slot, preventing splashing liquid from seeping in.

[0010] As a preferred technical solution of the present invention, an installation slot is provided on the end surface of the transmission seat.

[0011] By setting the mounting slot, the vibrating end of the root canal washer can be inserted into the mounting slot on the transmission seat, thereby completing the assembly for root canal cleaning.

[0012] As a preferred technical solution of the present invention, the flushing needle is a component made of antibacterial POM plastic.

[0013] By such arrangement, the needle washing device has good bacteria-inhibiting and mildew-proofing properties.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model provides a flushing needle with a triangular cross-section at the end, so that the end of the flushing needle can form three corners, and arc edges are provided at each corner of the end of the flushing needle, which is convenient for conveying the filling paste and ensuring that the paste filling effect is sufficient and compact. The arc edges on the flushing needle are used to quickly remove the pulp calcification in the root canal, ensuring the thoroughness of the root canal flushing and decontamination, and making the cleaning effect cleaner.

[0016] 2. The utility model fixes the scale assembly on the outside of the needle column through the scale assembly and the protective cover, thereby improving the overall structural strength of the needle column. The protective cover can shield and protect the joint between the vibration end and the mounting slot, preventing the infiltration of splashed liquid, which is conducive to ensuring reliability of use.
