Improved needle structure for root canal charger {Cap needle for dental}

The present invention relates to an improved structure of the needle for the root canal charger, and more particularly, a guide made of brass and made of a mounting cap and silver (G) in a gun-shaped root canal charger and integrally mounted to the cap part. The present invention relates to an improved root canal charger needle structure capable of eliminating the trouble of coupling the guide portion to the cap portion and making the guide portion made of silver to impart thermal conductivity and bendability.

In general, as a method for treating rotten teeth in a dental clinic, a rotten portion of a tooth is removed using a puncturing tool and a root canal, which is a treated portion, is filled with a filling material under a state of being sealed.

As mentioned above, the filling of the root canal is usually done with a cutter-percha cone, and at room temperature extracted from the trees of the genus Saguiaceae of the Sapotaceae and Payena genus, which are native to the Malay archipelago. Becomes rubber. This is commonly called White Gutta Percha. Zinc oxide, barium sulfate, wax, pigment, etc. are added to the plate and rolled or mixed in a mixer, etc., and then cut into plates to form conical shapes for each size. Cutter-percha cone is the most commonly used material for the root canal filling material, and it is known to be the most suitable for living body, so it has little toxicity to root root.

The commercially available cutter-percha cones consist of a standardized cone and an accessory cone, which are made in the same form as a dental file. In the treatment of nerves, as a puncture tool, the infected nerve tissue is removed through rotation and cutting, and a conical hollow space is left in the root canal. In order to fill the empty space no more infectious agents, a cuter-percha cone of the same size as that of the drilling tool is selected and filled, and usually one cuter-percha cone is required. This occurs when puncturing the root canal with a puncture instrument, due to the skill of the operator rather than the inaccuracy of the instrument.

The root canal filling, which is not the same as the drilling tool, is filled with the standard cuter-percha cone at the end, and the remaining empty space is filled with the auxiliary cone using a spreader to complete the root canal filling. The method of filling the root canal with the cutter-percha cone described above is not only painful and painful for the patient, but also can not fill the adjacent canal, which is not the main root canal. It often happens.

As described above, various devices for filling the root canal filling in the root canal have been developed, and these devices include a pressure pen and an injection gun. Referring to FIG. 4, the conventional injection gun and the root canal charger 10 have a general gun shape in which a trigger 12 is mounted, and a plunger 14 for pressurizing a filling is disposed at one side and a charging at the other end. The case 16 is mounted, the cap 20 is screwed to the layered case 16 so that the softened filling can be discharged, and the needle 30 having a predetermined length is detachably coupled to the cap 20.

However, the needle 30 described above has a problem that work is cumbersome and often lost because it is used in combination with the cap 20, and there is a problem that the thermal conductivity of the needle 30 is remarkably inferior. (30) This apparent problem was found.

The present invention is devised to solve the conventional problems as described above, the purpose of the present invention is made of brass and the gun (GUN) root canal charger is made of a mounting cap and silver (Ag) as well as integral to the cap portion By providing a guide portion to be mounted, it is possible to eliminate the hassle of coupling the guide portion to the cap portion, and to provide a structure for the needle for the root canal charger that can give the thermal conductivity and bendability by making the guide portion with silver.
