[0048] Example 1:
[0049] This embodiment provides a modular dental root canal treatment instrument, including an operating table 1. For example... Figure 1-2 As shown, the operating table 1 in this embodiment integrates a bur disinfection module 2, a root canal measurement module 3, a gutta-percha point trimming module 4, and a gutta-percha point disinfection module 5.
[0050] The needle sterilization module 2 of this embodiment includes a first body 21, which has a plurality of needle insertion holes 22 and a gutta-percha point placement hole 23. A gutta-percha point placement tube 24 for storing gutta-percha points is inserted into the gutta-percha point placement hole 23.
[0051] The root canal measurement module 3 of this embodiment includes a second body 31. The top surface of the second body 31 has a root canal instrument measuring hole 32 for measuring root canal instruments of different lengths. The second body 31 has a stepped length scale 33 at the bottom of the root canal instrument measuring hole 32. The second body 31 also has a measuring groove 34 for measuring the length of root canal instruments.
[0052] The gutta-percha tip trimming module 4 of this embodiment includes a third body 41, which is provided with gutta-percha tip insertion holes 42 adapted to different gutta-percha tip models, and a cutting component 43 for cutting the tip of the gutta-percha tip is provided inside the third body 41.
[0053] The gutta-percha point disinfection module 5 of this embodiment includes a fourth body 51, and the fourth body 51 is provided with a plurality of gutta-percha point soaking tanks 52 for soaking and disinfecting gutta-percha points.
[0054] In this embodiment, the third body 41 is located between the first body 21 and the second body 31, and the first body 21, the second body 31 and the third body 41 are all connected to the same long side of the fourth body 51.
[0055] The dental root canal treatment instrument in this embodiment is modularly designed, integrating functions such as bur disinfection, root canal measurement, gutta-percha storage, trimming, and disinfection onto a single workbench. This design conforms to the operating habits of medical staff, reduces the frequency of changing different instruments due to the numerous operating steps, and greatly improves work efficiency.
[0056] Example 2:
[0057] This embodiment provides a modular dental root canal treatment instrument, including a worktable 1. The worktable 1 in this embodiment integrates a bur disinfection module 2, a root canal measurement module 3, a gutta-percha point trimming module 4, and a gutta-percha point disinfection module 5.
[0058] The difference from Embodiment 1 is that the top surfaces of the first main body 21, the second main body 31, the third main body 41, and the fourth main body 51 in this embodiment are flush. The first main body 21 and the second main body 31 have the same height. The fourth main body 51 is flush with the bottom surfaces of the first main body 21 and the second main body 31 through the support plates 511 on both sides.

[0059] In this embodiment, the first main body 21, the second main body 31, the third main body 41, and the fourth main body 51 together form the entire frame of the operating table 1, and the whole is a cuboid structure. Since the bottoms of the first main body 21, the second main body 31, and the fourth main body 51 are flush, the entire operating table 1 can be placed stably on the table, greatly enhancing its stability during use. A gap is left between the bottom surface of the third main body 41 and the bottom surfaces of the first main body 21 and the second main body 31, allowing the gutta-percha tip debris trimmed by the gutta-percha tip trimming module 4 to fall naturally.
[0060] Example 3:
[0061] This embodiment provides a modular dental root canal treatment instrument, including a worktable 1. The worktable 1 in this embodiment integrates a bur disinfection module 2, a root canal measurement module 3, a gutta-percha point trimming module 4, and a gutta-percha point disinfection module 5.
[0062] The difference from Example 1 is that, as Figure 3As shown, the bur sterilization module 2 of this embodiment includes a first body 21, on which a plurality of bur insertion holes 22 and gutta-percha point placement holes 23 are provided. A gutta-percha point placement tube 24 for storing gutta-percha points is inserted into each of the gutta-percha point placement holes 23.

The diameters of the gutta-percha point placement holes 23 on both sides are different, allowing for the placement of root canal treatment files and nickel-titanium preparation files of different sizes.
[0063] like Figure 4 As shown, the root canal measurement module 3 of this embodiment includes a second body 31. The top surface of the second body 31 has several root canal instrument measuring holes 32 for measuring root canal instruments of different lengths. At the bottom of each root canal instrument measuring hole 32, the second body 31 has a stepped length scale 33, which includes multiple steps. Each root canal instrument measuring hole 32 corresponds to one of these steps. In this embodiment, each root canal instrument measuring hole 32 is accompanied by a first identifier 321 corresponding to its measurement height. The height difference between two adjacent root canal instrument measuring holes 32 is 0.5 mm. The first identifiers 321 are numbered sequentially from 11 to 28 next to the corresponding root canal instrument measuring holes 32. The second body 31 of this embodiment also has a measuring groove 34 for measuring root canal length. The measuring groove 34 is located in the center of the second body 31, and the root canal instrument measuring holes 32 are distributed on both sides of the measuring groove 34.
[0064] like Figure 5-6 As shown, the gutta-percha point trimming module 4 of this embodiment includes a third body 41. The third body 41 is provided with gutta-percha point insertion holes 42 adapted to different gutta-percha point models. The third body 41 contains a cutting element 43 for cutting the tip of the gutta-percha point. The third body 41 of this embodiment includes an upper plate 411 and a lower plate 412, which are fastened together by screws. A push block 44 is horizontally provided between the upper plate 411 and the lower plate 412. The push block 44 is connected to the inner wall of the upper plate 411 by a spring 45. The cutting element 43 is mounted on the push block 44. The cutting element 43 has a sheet-like structure and the sheet has cutting holes 431 that correspond one-to-one with the gutta-percha point insertion holes 42. The push block 44 includes an integrally connected push block body 441 and a push-pull handle 442. In its natural state, when the gutta-percha point to be trimmed is inserted into the gutta-percha point insertion hole 42, it can extend into the corresponding cutting hole 431. Then, by pushing and pulling the handle 442, the push block body 441 can be driven to move inward, thereby driving the cutting element 43 on the push block body 441 to cut and trim the tip of the gutta-percha. The middle part of the push block body 441 and the bottom of the lower plate 412 are both through-type, forming a through channel for the cut end of the gutta-percha point to fall. In this embodiment, a second mark 421 corresponding to the gutta-percha point model is provided next to the gutta-percha point insertion hole 42, which is designated as 20-120.
[0065] like Figure 7 As shown, the gutta-percha disinfection module 5 of this embodiment includes a fourth main body 51, on which several gutta-percha soaking tanks 52 for soaking and disinfecting gutta-percha points are provided. Each gutta-percha soaking tank 52 in this embodiment is provided with an inclined plate 53, the maximum depth of which is 1 cm. Each inclined plate 53 is provided with a gutta-percha receiving groove 54 for accommodating the gutta-percha point. The gutta-percha point to be disinfected is placed in the gutta-percha receiving groove 54, and then sodium hypochlorite disinfectant is injected into the gutta-percha soaking tank 52 for soaking and disinfection. In this embodiment, each gutta-percha soaking tank 52 is provided with a third identifier 521 corresponding to the root canal location. The eight gutta-percha soaking tanks 52 are arranged side by side and are sequentially labeled MB1, MB2, ML, DB, P, L, B, and D.
[0066] In this embodiment, the third main body 41 is located between the first main body 21 and the second main body 31, and the first main body 21, the second main body 31, and the third main body 41 are all connected to the same long side of the fourth main body 51. The first main body 21 has a length of 3.8cm and a width of 5cm; the second main body 31 has a length of 5cm and a width of 5cm; the third main body 41 has a length of 3.2cm and a width of 5cm; and the fourth main body 51 has a length of 12cm and a width of 3.5cm.
[0067] This embodiment combines the bur sterilization module 2 with the root canal measurement module 3. Common root canal files and nickel-titanium files required for root canal treatment are directly prepared on the bur sterilization rack. When measurement is needed, they can be placed directly on the root canal measuring table. The file length can be adjusted on the measuring table by moving the file and adjusting the "Stop" button. The bur sterilization rack has three cylindrical gutta-percha point holders 24 for storing gutta-percha points. An appropriate amount of gutta-percha points can be selected and prepared before operation. When measuring gutta-percha points, they can be directly picked up with tweezers and placed on the root canal measuring table. This eliminates the need for operators to prepare additional measuring rulers, reducing the steps of changing tools and the additional instrument sterilization process.
[0068] Furthermore, this embodiment combines the root canal measurement module 3 with the gutta-percha trimming module 4. The operator can directly place the gutta-percha point on the corresponding size prepared for the root canal and trim it to the appropriate size. The trimmed gutta-percha point is then placed directly into the corresponding length hole on the root canal measuring stage according to the working length of the root canal. Tweezers are used to pick up the required length from the hole, avoiding the need for additional use of a root canal measuring ruler and frequent instrument exchanges.
[0069] Furthermore, in this embodiment, the root canal measurement module 3 is combined with the gutta-percha disinfection module 5. The gutta-percha points that have been trimmed to the correct size and have a determined working length can be directly placed into the gutta-percha soaking tank 52 according to the root canal location (MB1, MB2, ML, P, L, B, D) and marked points. This avoids mixing different sizes of gutta-percha points of the same color in the oral instrument tray while they are being disinfected by soaking in sodium hypochlorite.
[0070] Furthermore, this embodiment integrates the bur disinfection module 2, root canal measurement module 3, gutta-percha point trimming module 4, and gutta-percha point disinfection module 5 into one unit, which can withstand high-temperature and high-pressure disinfection at 135℃, making the root canal treatment process simpler. During operation, there is no need to frequently alternate between handling instruments, improving the doctor's operational efficiency, reducing the gutta-percha point confusion rate, and improving treatment accuracy. This reduces the operation time required for root canal treatment and shortens the time the patient needs to keep their mouth open, thus achieving the goal of comfortable treatment.
[0071] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
