Description

Tooth root canal cleaning needle

Technical Field

The utility model relates to a tooth root canal treatment technical field specifically is tooth root canal cleaning needle.

Background

Nowadays, people pay more and more attention to the health of teeth, and dental treatment tools for teeth are provided, wherein a cleaning needle is one of important tools for cleaning the root of the teeth. Needles for tooth root cleaning now have the following drawbacks: the side surface can not reliably discharge water at the same time, the depth of the small side hole is not easy to guarantee, the depth is low, easy to bend and break, the whole structure is complex, the processing cost is high, and time is wasted, so that the stability of the product quality is reduced, the size of the tip part of the needle tube is large, the depth of the root canal therapy is reduced, and meanwhile, the front end of the needle head is in a non-pointed spherical shape, so that the operation is not easy, and the use is inconvenient; in view of these drawbacks, it is necessary to design a root canal cleaning needle for teeth.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tooth root canal washs syringe needle, the size of needle tubing point portion has increased root canal therapy's degree of depth, has simplified the technology, has improved product quality's stability, because the front end cap is the hemisphere, has strengthened the convenience of using.

The purpose of the utility model can be realized by the following technical scheme:

the tooth root canal cleaning needle comprises a needle seat, a needle tube, a plug and water outlets, wherein the rear end of the needle tube is inserted into a through hole in the center of one side of the needle seat, the joint of the needle tube and the through hole is bonded through glue, the front end of the needle tube is welded into the plug through pressing, the plug is hemispherical, and the needle tube is symmetrically provided with one water outlet at the position close to the two sides of the front end along the axis direction;

wherein, the water outlet is in the shape of a water drop.

As a further aspect of the present invention: the needle tube is a stainless steel material component.

The utility model has the advantages that: the water outlets are symmetrically arranged at the front end of the needle tube relative to the axis of the needle tube, the positions of the two water outlets are consistent, so that the water outlets achieve uniform pressure, the water outlets are of a water drop shape, the water outlet direction is ensured to be sprayed out in the front side direction, the water outlets are opened in the middle of the needle tube, the power concentration phenomenon of the needle tube is not generated, the possibility of breakage and bending deformation of the needle tube is avoided, after the water outlets at the front end of the needle tube are opened, the front ends at the two sides are closed together by external force, the outer diameter size is reduced, so that the needle tube can extend into the deep root canal of a tooth to be cleaned and treated, the structure can ensure that the two sides of the needle tube can uniformly spray water simultaneously, overcomes the defect of easy bending of the traditional product, reduces the size of the tip of the needle tube, increases the treatment depth, simplifies the, the convenience of use is enhanced.

Drawings

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic view of the front end of the needle cannula of the present invention;

in the figure: 1. a needle head seat; 2. a needle tube; 3. a plug; 4. and (7) a water outlet.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-2, the tooth root canal cleaning needle comprises a needle base 1, a needle tube 2, a plug 3 and water outlets 4, wherein the rear end of the needle tube 2 is inserted into a through hole at the central position of one side of the needle base 1, the joint of the needle tube 2 and the through hole is bonded through glue, the front end of the needle tube 2 is pressed and welded to form the plug 3, the plug 3 is hemispherical, and the needle tube 2 is symmetrically provided with the water outlets 4 at positions close to the two sides of the front end along the axial direction;

wherein, the water outlet 4 is in a drop shape;

wherein, the needle tube 2 is a stainless steel material component;

the manufacturing steps of the integral structure include that the front end of the needle tube 2 is cut through online cutting equipment or laser equipment to form a water outlet 4, then the front end of the needle tube 2 is pressed to be combined, the size is reduced, welding of a front end plug 3 is facilitated, welding processing is carried out on a laser welding machine after the front end of the needle tube 2 is pressed to enable the front end to form the hemispherical plug 3, and the welded needle tube 2 and the needle head seat 1 are bonded together.

The utility model discloses a theory of operation: the water outlets 4 are symmetrically arranged at the front end of the needle tube 2 relative to the axis of the needle tube 2, the positions of the two water outlets 4 are consistent, so that the water outlets 4 achieve uniform pressure, the water outlets 4 are of a water drop type, the water outlet direction is sprayed out in the front side direction, the water outlets 4 are opened in the middle of the needle tube 2, the needle tube 2 does not generate a power concentration phenomenon, the possibility of fracture and bending deformation of the needle tube 2 is avoided, after the water outlets 4 at the front end of the needle tube 2 are opened, the front ends at the two sides are closed together by external force, the outer diameter size is reduced, so that the needle tube 2 can extend into the deep part of the root canal of a tooth to be cleaned and treated, the structure can ensure that the two sides of the needle tube 2 spray water uniformly at the same time, overcome the defect of the traditional product that the needle tube is easy to bend, the size of the tip part, because the front end plug 3 is hemispherical, the use convenience is enhanced.
