Description

Tool for heating working tip and treating root canal

Technical Field

The invention belongs to the field of dentistry, and particularly relates to a heating working tip and a tool for root canal retreatment.

Background

Root canal therapy is the most effective treatment of choice for endodontic and periapical diseases. The principle of root canal treatment is to remove infectious agents from the root canal by mechanical and chemical means, and to prevent the occurrence of periapical lesions or to promote the healing of already occurring periapical lesions by filling the root canal and sealing the crown. The basic steps of root canal treatment are as follows: opening marrow, preparing root canal, sterilizing root canal and filling root canal. Among them, the use of gutta-percha for root canal filling plays an extremely important role in the entire root canal treatment process. The root canal has many small branches and branches, and in the case of such a complicated root canal system, failure of root canal treatment is inevitable, and the first choice after failure is to perform root canal retreatment.

The gutta-percha filled in the root canal needs to be taken out for the root canal retreatment, at present, no tool can completely take out the gutta-percha in the root canal, the gutta-percha is easy to remain in the taking-out process, or the gutta-percha is pushed out of the root canal hole, and complications of the root canal treatment are caused.

Disclosure of Invention

In order to solve the technical problem of difficulty in taking out gutta-percha in the prior art, the invention provides a heating tip and a tool for root canal retreatment, and solves the technical problem.

The technical scheme adopted by the invention for solving the technical problems is as follows:

one aspect of the present invention provides a heated tip for gutta-percha extraction, comprising: the wide end of the working tip is connected with a heating device; concave-convex structure, concave-convex structure configuration is in the narrow end of work point, concave-convex structure is along with the work point forms with the gutta-percha after entering into the gutta-percha and is connected and restriction the work point is deviate from in the gutta-percha.

The utility model discloses a heating work point, be used for taking out of gutta-percha in the root canal, when taking out, utilize heating device to heat the heating work point earlier in order to conveniently insert refrigerated gutta-percha, after the work point inserted the gutta-percha, the part that gutta-percha and concave-convex structure contacted can soften and fuse into concave-convex structure, stop heating, wait that the work point cools off, the gutta-percha resolidification, the gutta-percha that has fused into concave-convex structure at this moment can form fine and close and firm connection with concave-convex structure, take out the work point, the concave-convex structure of work point can apply an axial power for the gutta-percha and thereby take out the gutta-percha, thereby solved the technical problem that the gutta-percha takes out difficulty among the prior art, the part that the heating work point of this application inserted the gutta-percha occupies that the volume is less simultaneously, can avoid the gutta-percha to be released apical pore, and the in-process dentist of taking out of heating work point only need one hand operation just can, the other hand is used for assisting work, and the safety in the operation process is improved.

Furthermore, the concave-convex structure is formed by a plurality of thick sections and thin sections which are arranged in a staggered mode.

Furthermore, a limiting surface for limiting the working tip to be separated from the gutta-percha is formed at one end, facing the wide end of the working tip, of the thick section.

Further, the end of the thick section facing the narrow end of the working tip is formed with a guide surface for easy insertion.

Further, the relief structure is formed by a plurality of barbs disposed on an outer wall of the tip.

Further, the concave-convex structure is formed by a plurality of protrusions which are arranged on the outer wall of the operating tip and protrude out of the outer wall of the operating tip.

In another aspect of the invention, there is provided a tool for endodontic retreatment including the heated tip described above.

Based on the technical scheme, the invention can realize the following technical effects:

The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
