The shape of the needle stand is cylindrical and the needle body is conic. The conic needle body is provided with a spiral groove. An overflow hole communicated with the needle core is arranged at intervals at the bottom of the groove and from the needle point to the intermediate section of the needle body. The needle point is conic and is closed. Because of adopting the structure, the conic thread tooth stump tube flushing needle is matched with the shape of the inner wall of a tooth stump tube. An overflow hole is positioned at the bottom of a thread groove and is difficult to squeeze and block. The rotational flow increases the water flow force to gain a better cleaning effect. The cleaned foul solution can not overflow from a stump point hole to cause ache and secondary inflammation.

Description

A kind of root canal flushing needle

Technical field

This utility model relates to a kind of medical root canal flusher, and can prevent that especially flushing liquor from overflowing apical foramen of tooth, and can strengthen developing result, and the not susceptible to plugging root canal flushing needle of spillway hole.

Background technology

The dentist adopts a kind of root canal flushing needle often carrying out odontotherapy, mostly flushing needle commonly used now is by general injection needle self-control, with its tip blunt, the somebody does several side openings on the needle body of injection needle, this self-control flushing needle has inconvenience in use, and easily forms many iatrogenic injuries.As dark excessively in the needle tip insertion root canal, the slough in the root canal, antibacterial and pathologic product thereof can be flushed to outside the apical foramen of tooth, cause that patient has an intense pain and the secondary inflammation of apex of root of tooth tissue; Side opening is pushed by the root canal inwall, and it is not smooth to cause flushing liquor to flow out; It is non-directional to wash excessive current, influences developing result.

Summary of the invention

The purpose of this utility model is exactly the above problem that exists at existing self-control flushing needle, provides a kind of and can prevent that flushing liquor from overflowing apical foramen of tooth, and form eddy flow reinforcement developing result, the not susceptible to plugging root canal flushing needle of spillway hole.

The purpose of this utility model is to realize like this, this root canal flushing needle comprises the needle stand and the needle body that connects thereon, described needle stand profile is a cylindrical shape, the described needle body is coniform, on the cone shape needle body, be provided with spiral groove, be provided with a spillway hole at channel bottom middle part from the needle point to the needle body every a segment distance and communicate the tapered sealing of needle point with nook closing member.

Owing to adopt said structure, tapered thread root canal flushing needle and root canal inner wall shape adapt, and spillway hole is positioned at the screw thread bottom of trench and is difficult for crowded blocking up, and eddy flow increases current strength, make developing result better, the soiling solution of flushing can not overflow apical foramen of tooth and cause pain and secondary inflammation outward.
