Description

Technical Field

[0001] The utility model relates to the technical field of gutta-percha tip cutting, in particular to a quick-cutting device for gutta-percha tips. Background Art

[0002] Gutta-percha tip is a solid root canal filling material used in dental endodontic treatment. It is generally made of rubber and has good plasticity. It can become soft when heated to 40 degrees Celsius and harden after cooling. It has tight filling and good tissue affinity. It can be easily removed from the root canal. It is non-conductive and non-electrical. It needs to be cut off during the application process. In this process, a gutta-percha tip cutting device is needed.

[0003] When the existing gutta-percha point cutting device is used, it generally performs the cutting task from top to bottom. However, since the gutta-percha point is relatively hard at room temperature, it takes a lot of time and effort to cut it, and it is easy to cause the end surface to be uneven. Utility Model Content

[0004] The utility model aims to provide a quick-cutting device for gutta-percha points, which solves the above-mentioned background problems by replacing a cutting method from top to bottom with a cutting method inclined downward.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] See also Figure 1-Figure 5 As shown, the utility model is a quick-cutting device for gutta-percha tips, comprising a mounting chamber 1, a bearing plate 3 is mounted at the bottom of both ends of the mounting chamber 1, and the cross-sectional shape of the bearing plate 3 is a trapezoid, the bottom of the mounting chamber 1 is in an open state, and at the same time, the inclined surface of the bearing plate 3 facilitates the falling of possible debris;

[0029] like Figure 1 and Figure 4 As shown, a collecting bin 2 is installed at one end of the installation bin 1, a first through hole 4 is opened at one end of the installation bin 1 close to the collecting bin 2, and a second through hole 5 is reserved at the other end of the installation bin 1, the central axis of the first through hole 4 coincides with the central axis of the second through hole 5, and the first through hole 4 is a flared type, so that the cut and broken part close to the collecting bin 2 can fall into the collecting bin 2 at an angle;

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a fixed bin 6 is installed on one side of the top of the installation bin 1, a movable rod 7 is arranged inside the fixed bin 6, and the movable rod 7 passes through the fixed bin 6 and extends to the inside of the installation bin 1, a first spring 8 is connected between the movable rod 7 and the fixed bin 6, and a cutting blade body 9 is installed at the bottom of the movable rod 7, the movable rod 7 is inclined, and the movable rod 7 forms a sliding structure with the installation bin 1 and the fixed bin 6 respectively, the top of the pressing rod 10 is provided with an anti-slip pattern, and the pressing rod 10 and the installation bin 1 form a sliding structure, the bottom of the pressing rod 10 is provided with a mounting groove 12, and the inner portion of the mounting groove 12 A roller assembly 13 is installed on the side, and the elastic force of the first spring 8 is greater than the elastic force of the second spring 11, so that when the worker presses the cutting blade body 9 by pressing the pressing rod 10, the cutting blade body 9 can move obliquely downward and complete the cutting task. At the same time, the roller assembly 13 can replace the pressing rod 10 to directly contact the cutting blade body 9, so that when the cutting blade body 9 moves horizontally relative to the pressing rod 10, the roller assembly 13 can rotate accordingly to reduce wear. In the application process, multiple groups of roller assemblies 13 can be set to ensure the contact surface with the cutting blade body 9;

[0031] Example 2

[0032] like Figure 4 As shown, the follower mechanism includes a connecting rod 14, which is installed at one end of the bottom of the pressing rod 10 close to the collecting bin 2. A closed protective plate 15 is installed at the bottom of the connecting rod 14. When the pressing rod 10 is pressed to implement cutting, the closed protective plate 15 can move downward to basically close the collecting bin 2, thereby avoiding splashing of the cut part.

[0033] The working principle of the utility model is as follows: insert the gutta-percha tip through the second through hole 5, and extend through the first through hole 4 to the inside of the collecting bin 2, and press the pressing rod 10 at the same time, so that the pressing rod 10 squeezes the cutting blade body 9 downward, and the movable rod 7 slides with the fixed bin 6 and the mounting bin 1 respectively, and the elasticity of the first spring 8 makes the cutting blade body 9 move obliquely downward along the sliding track of the movable rod 7, so that the gutta-percha tip can be cut from top to bottom while further applying a certain lateral cutting force, which is more labor-saving and convenient, and can avoid the situation that the end surface is not flat due to excessive squeezing.

[0034] When the above-mentioned cutting process is about to be completed, the pressing rod 10 drives the closing protective plate 15 on the connecting rod 14 to move down to basically close the collecting bin 2, so as to avoid splashing of the cut part. After the cutting is completed, the pressing rod 10 is released. Under the elastic action of the second spring 11 and the first spring 8, the pressing rod 10 and the cutting blade body 9 return to their initial state, and the gutta-percha tip is taken out of the installation bin 1. At the same time, the closing protective plate 15 releases the closure of the collecting bin 2, and the cut part can be poured out of the collecting bin 2.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
