Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-3 The present invention provides a technical solution: a gutta-percha tip trimmer and cutter, comprising a base 110, a row of first circular holes 111 and a row of second circular holes 112 symmetrically arranged at the top of the base 110, a strip groove with open ends on one side of the base 110, the strip groove communicating with the bottom end of the first circular holes 111, a plurality of first circular grooves 113 of different depths corresponding one-to-one with the first circular holes 111 at the bottom end of the strip groove, a cutting component 120 installed at the bottom end of the inner wall of the strip groove, a groove communicating with the second circular holes 112 on the other side of the base 110, a support block 130 installed in the groove, a second circular groove 131 corresponding one-to-one with the second circular holes 112 at the top of the support block 130, and first cutting blades of different tapers installed in the second circular groove 131.

[0027] In some specific implementations, a marking plate 114 is symmetrically fixedly mounted on the top of the base 110. The marking plate 114 records the corresponding cutting length and dimensions. This provides a clear dimensional reference for the placement of the gutta-percha points. In actual operation, the operator can quickly and accurately insert the gutta-percha point into the corresponding first round hole 111 or second round hole 112 according to the markings on the marking plate 114, without the need for repeated measurement and comparison. This greatly improves the efficiency of cutting gutta-percha points, reduces operation time, and also reduces cutting errors caused by operator unfamiliarity.

[0028] In some specific implementations, a third circular groove is symmetrically arranged on one side of the base 110. A first spring 115 is fixedly installed on the inner wall of the third circular groove. A support bar 116 is fixedly installed at one end of the first spring 115. The first circular groove 113 is located at the contact point between the support bar 116 and the base 110. The top end of the support bar 116 and the bottom end of the groove are on the same plane. The support bar 116 and the base 110 form a cuboid. This arrangement facilitates cleaning of the inside of the first circular groove 113. Insert rods 117 are fixedly installed at the four corners of one side of the support bar 116. A matching insertion hole is provided on one side of the base 110. The insertion rod 117 is slidably connected to the inner wall of the insertion hole, and the insertion rods 117 are symmetrically arranged on both sides of the first spring 115. This improves the stability when the support bar 116 is pulled.

[0029] Please see Figure 4 The cutting assembly 120 includes a slide plate 121, an insert plate 122, and a second cutting blade 123. The slide plate 121 is slidably mounted on the bottom of the inner wall of the strip groove. The insert plate 122 is T-shaped, and a slot matching the slide plate 121 is provided on one side of the slide plate 121. The second cutting blade 123 is fixedly mounted on one end of the insert plate 122, and a push plate 124 is fixedly mounted on one end of the slide plate 121. The top of the second cutting blade 123 is on the same plane as the top of the slide plate 121, and the sum of the depth of the top of the second cutting blade 123 and the depth of the first circular groove 113 is the precise cutting length. The operator only needs to push the push plate 124 to easily move the slide plate 121, thereby enabling the second cutting blade 123 to cut the gutta-percha tip. Meanwhile, the sum of the tip of the second cutting blade 123 and the depth of the first circular groove 113 is designed to achieve a precise cutting length. Combined with different depth settings of the first circular groove 113, it can meet the precise cutting requirements for different lengths of gutta-percha points, ensuring that the length of the gutta-percha points after cutting meets the requirements of root canal treatment, improving cutting accuracy, and enhancing the compatibility between gutta-percha points and root canals.

[0030] In some specific implementations, a baffle 125 is rotatably mounted on one side of the slide plate 121, and the baffle 125 is fixedly connected to the insert plate 122 by a first bolt 126. When the second cutting blade 123 wears out or needs to be replaced with a different type of cutting blade to meet special cutting requirements, the operator only needs to unscrew the first bolt 126, rotate the baffle 125, and remove the insert plate 122 from the slot of the slide plate 121 to replace the second cutting blade 123. This structural design improves the flexibility and maintainability of the device, allows for timely adjustment of the cutting components according to actual usage, extends the service life of the device, and reduces operating costs.

[0031] In some specific implementations, a guide block 127 is fixedly installed at the bottom of the slide plate 121. A guide groove matching the guide block 127 is provided at the bottom of the inner wall of the strip groove. The guide block 127 is slidably connected to the inner wall of the guide groove. A guide rod is fixedly installed between the two sides of the inner wall of the guide groove, and the guide block 127 is slidably mounted on the guide rod. During the cutting process, the slide plate 121 can move smoothly along the guide groove and guide rod, avoiding wobbling or deviation, ensuring that the second cutting blade 123 always cuts the rubber tip along the predetermined trajectory, thereby improving cutting accuracy and making the cut surface smoother. At the same time, this stable guiding structure also enhances the overall stability of the device, reducing the adverse effects on the cutting effect caused by unstable slide plate movement.

[0032] Please see Figure 5 and Figure 6The support block 130 is fixedly connected to the groove by the second bolt 132. The inner wall of the groove is provided with an elastic groove, and a second spring 133 is symmetrically fixedly installed on the inner wall of the elastic groove. An elastic plate 134 is fixedly installed at one end of the second spring 133, and the elastic plate 134 is in close contact with the support block 130. When the support block 130 is installed in the groove, the support block 130 and the elastic plate 134 are in close contact, and the second spring 133 is deformed by compression. This allows for easy replacement of different support blocks or the first cutting blade to meet the cutting requirements of different gutta-percha taper angles, improving the functionality of the device. The second spring 133 and the elastic plate 134 act as a buffer during the installation of the support block 130, reducing impact during installation and protecting device components. During cutting, they enhance the stability of the support block 130, allowing it to better support the gutta-percha tip, preventing cutting errors caused by device shaking, ensuring cutting accuracy, and improving cutting quality.

[0033] Working principle: When cutting length, the rubber tip enters the connected strip groove through the first circular hole 111. Since the bottom of the strip groove is provided with multiple first circular grooves 113 of different depths, each corresponding to the first circular hole 111, the rubber tip can be placed in the first circular groove 113 of the corresponding depth as needed. This pushes the push plate 124 to move the slide plate 121. The movement of the slide plate 121 drives the second cutting blade 123 to cut through the insert plate 122. After cutting, the support bar 116 can be pulled to let the cutting residue fall out for easy cleaning. When dimensional cutting is required, one end of the rubber tip is inserted into the second circular hole 112, so that the bottom of the rubber tip contacts the second circular groove 131 at the top of the support block 130. The second circular groove 131 is equipped with first cutting blades of different tapers for cutting. Finally, when the cutting blade needs to be replaced, only the first bolt 126 and the second bolt 132 need to be removed for replacement.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
