Description

Technical Field

[0001] This utility model relates to the field of dental medical devices, and in particular to a gutta-percha point cutter. Background Technology

[0002] In root canal treatment, gutta-percha points are tapered materials used for permanent filling of root canals. They are mainly made of gutta-percha and zinc oxide, have good plasticity, soften when heated to 40 degrees Celsius, and harden when cooled. They provide a tight filling, have good tissue compatibility, can be easily removed from the root canal, and are non-thermal and non-electrical.

[0003] When filling root canals with trial points after root canal preparation, it is often found that the apical foramen is too wide or damaged. Matching gutta-percha points may extend beyond the apical foramen, while larger gutta-percha points with the same taper often become stuck in the middle of the root canal. If the difference in apical foramen size is not significant, the points can be surgically cut and filled with a scalpel. However, if the root canal foramen is severely damaged or particularly wide, the cuts may be inaccurate. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components.

[0023] See Figure 1 and Figure 3 This application provides a gutta-percha point cutting device, including a main body 20, a rotating structure 40, and a cutting structure 60. The main body 20 has a hollow cavity 202 and a first opening 204, the first opening 204 being disposed at the bottom of the hollow cavity 202 for receiving gutta-percha points 80. The cutting structure 60, disposed below the hollow cavity 202, is used to cut off the tip of the gutta-percha point and has multiple second openings 602 of different sizes, the edges of the second openings being thin blade-shaped. The rotating structure 40 is connected to the main body 20 and the cutting structure 60, for rotatably fixing the cutting structure 60 to the main body 20.

[0024] Compared to existing gutta-percha point cutting devices that rely on blades for active cutting and have slightly lower precision, this application achieves active cutting of gutta-percha points by rotating the main body, eliminating the need for the operator to move the gutta-percha points, reducing the likelihood of errors in the cutting width, and ensuring precise cutting.

[0025] See Figure 1The hollow cavity 202 can be frustum-shaped, wider at the top and narrower at the bottom, or cylindrical. There can be at least one hollow cavity 202. Preferably, when there are multiple hollow cavities 202, these hollow cavities 202 have different specifications, with each hollow cavity 202 having one specification. Each hollow cavity 202 can have one first opening 204. When there are multiple hollow cavities 202, there are multiple first openings 204, and the multiple first openings 204 have multiple different sizes, with each first opening having one size.

[0026] Continue reading Figure 1 The rotating structure 40 may be axial and disposed at the center of the main body 20.

[0027] See Figure 2 The cutting structure 60 can be in the form of a thin sheet, such as an ultrathin metal sheet or a blade. The sheet can be circular, and the second openings 602 can be arranged circumferentially. Each second opening 602 can have a size ranging from 250µm, 300µm, 350µm, 400µm up to 550µm, 600µm, 700µm, 800µm in diameter, corresponding to gutta-percha points #25, #30, #35, #40 up to #55, #60, #70, #80, respectively. When one of the second openings 602 is collinear with the first opening 204, a gutta-percha point 80 (see...) is formed. Figure 3 The hollow cavity 202 can preferably have two parts: one with a smaller first size and one with a larger second size. The hollow cavity with the first size has a smaller first opening, and the hollow cavity with the second size has a larger first opening. In use, the smaller first opening can be aligned with a second opening of 250µm, 300µm, 350µm, or 400µm, and the larger first opening can be aligned with a second opening of 550µm, 600µm, 700µm, or 800µm.

[0028] See Figure 3 A collection chamber can be connected below the cutting structure 60, which is used to collect the tip portion of the cut gutta-percha point 80. Preferably, the collection chamber can be made of a transparent material to facilitate observation of whether the first opening 204 and the second opening 602 are aligned.

[0029] When the collection chamber is made of non-transparent material, please refer to the following: Figure 2To facilitate determining whether the first opening 204 and the second opening 602 are aligned, the bottom surface of the main body 20 and the top surface of the cutting structure 60 can both be circular, with the diameter of the bottom surface of the main body 20 being larger than the diameter of the top surface of the cutting structure 60. A first straight line 201 can be provided on the bottom surface of the main body 20, with its extension passing through the center of the first opening 204. Multiple second straight lines 601 can be provided on the top surface of the cutting structure 60, with their extensions passing through the center of the second opening 602. When it is determined that a certain size of second opening 602 is needed for cutting gutta-percha points, the main body 20 is rotated until the first straight line 201 and the second straight line 601 of the second opening 602 are aligned, indicating that the first opening 204 and the second opening 602 are aligned.

[0030] In use, the gutta-percha point cutting device of this application is first inverted so that the cutting structure 60 is on top. Then, the main body 20 is rotated so that the first opening 204 is aligned with the second opening 602 of the required size. Finally, the gutta-percha point 80 to be cut is placed into the hollow cavity 202. After the tip of the gutta-percha point 80 passes through the channel formed by the first opening 204 and the second opening 602, the device body is rotated again so that the second opening 602 cuts the gutta-percha point 80. This application achieves active cutting of the gutta-percha point 80 by rotating the main body 20, eliminating the need for the operator to move the gutta-percha point. This reduces the likelihood of errors in the cutting width and ensures precise cutting. Because the second opening 602 of the required size is aligned with the first opening 204, the gutta-percha point 80 is cut when the cut surface meets the required width, providing a suitable gutta-percha point for root canal filling.
