Description

Dental pulp cannula explorer for dental root canal treatment {CANAL NAVIGATING DEVICE FOR DENTAL ENDODONTIC TREATMENT}

The present invention relates to a dental pulp canal searcher for searching for the entrance of a dental pulp canal during dental root canal treatment, and more particularly, to expand and detect the entrance of a dental pulp canal blocked due to calcification during dental root canal treatment using a probe or an endo file. The present invention relates to a dental pulp canal explorer for dental nerve treatment that expands the entrance of the pulp canal and then removes the nerve to treat the dental nerve.

Root canal treatment is a procedure that maintains the function of teeth by physically removing nerves, blood vessels, and other cellular tissues in the neural tube infected with bacteria inside the tooth, washing the empty space with a detergent, and then filling the space with a filling material. In other words, it is a treatment for preventing the loss of teeth due to damage to the gums due to an adverse effect on the outer gum bone of the root of the tooth due to infection of the neural tube.

1 is a view showing a conventional dental nerve treatment method.

Referring to Figure 1, the conventional dental nerve treatment process is as follows. When the tooth nerve becomes inflamed (see (a)), the pulp cavity 1c is opened by removing a part of the enamel 1e and dentin 1d using the handpiece 2 (see (b)). Subsequently, after removing the nerves in the pulp canal (nerve canal) 1f using the endo file 3, the pulp canal 1f and the pulp cavity 1c, and the enamel 1e and dentin 1d are treated with drugs and/or Fill with resin (4) (see (c) and (d)). Subsequently, the top of the enamel 1e is covered with the porous material 5 to complete the nerve treatment (see (e)).

However, in dental root canal treatment according to the prior art, after opening the pulp cavity 1c, the entrance (see 'A') of the pulp canal 1f connected to the pulp cavity 1c can be explored using a probe or endo file 3. In this case, the entrance of the pulp canal 1f can be easily found, but if the entrance of the pulp canal 1f is calcified and the entrance is narrowed, or if the entrance is completely blocked, the conventional probe or endofilament is narrowed or completely blocked. It is not easy to navigate the entrance of the blocked pulp canal 1f. As a result, there is a problem in that dental nerve treatment is complicated and treatment time is also increased.

Accordingly, the present invention has been proposed to solve the above-mentioned general problems.

An object of the present invention is to provide a dental pulp canal searcher for dental root canal treatment that can stably search for the dental pulp canal entrance even if the dental pulp canal entrance is clogged with calcification during dental root canal treatment.

In addition, another object of the present invention is for dental root canal treatment that can perform dental root canal treatment by effectively removing the nerve inside the pulp canal by expanding the entrance of the pulp canal using a probe or an endo file at the same time as searching for the entrance of the pulp canal. It is to provide a dimension canal explorer.

The present invention for achieving the above object is a main body including a holder and a fixing table extending from one end of the holder; A lighting lamp installed on the fixture to emit light to illuminate the surroundings; a photographing unit enlarging and photographing the surroundings using a magnifying glass installed on the fixing table; a control unit which controls operations of the lighting lamp and the photographing unit, and provides an enlarged image photographed by the photographing unit to a monitor through a wired or wireless network; And it provides a dental pulp canal explorer for dental nerve treatment including a probe or endo file detachably mounted on the main body.

In addition, the holder and the fixing rod may be integrally formed to have a fixed length in the longitudinal direction, or the fixing rod may be coupled to the holder by screwing or interference fitting, and the length may vary depending on the degree of coupling. there is.

In addition, one or a plurality of lighting lamps may be installed at the end of the fixing stand, and the magnifying glass may be installed at the center of the end of the fixing stand.

In addition, the probe or endo file may be detachably coupled to the inside of the mounting hole formed in the holder by screwing or interference fit.

In addition, a thread may be formed in the mounting hole to mount the probe or the endo file, or an inner diameter may be gradually narrowed in the depth direction.

As described above, according to the dental pulp canal searcher for dental root canal treatment according to the present invention, the surrounding area is brightened through a lighting lamp and an image obtained by enlarging the area around the entrance of the dental pulp canal using a photographing unit equipped with a magnifying glass is displayed on a monitor. By searching the entrance of the pulp canal while monitoring it through the dental pulp canal, even if the entrance of the pulp canal is blocked by calcification during dental root canal treatment, it is possible to stably search for the entrance of the pulp canal. The nerve of the tooth can be treated by effectively removing the nerve.
