Abstract
Description
Technical Field
[0001] This invention relates to the field of oral education technology, specifically to a tool for quantitative and uniform application of artificial calculus on a periodontal disease model used in oral education. Background Technology
[0002] Artificial calculus application in periodontal disease models is a crucial step in periodontology experimental teaching. Its core purpose is to provide learners with a near-clinical operational experience by simulating the characteristics of real calculus. Currently, the artificial calculus application process for periodontal disease models in oral medicine teaching still faces the following technical bottlenecks: First, application precision is difficult to control: Traditional manual application methods rely on the operator's spatial perception, making it difficult to accurately control the thickness and density distribution of the calculus material. Common clinical problems include excessive buildup at the cervical region, which can easily lead to distortion of the model's anatomical structure, missing application in proximal areas, affecting the simulation of periodontal pockets, and interfering with subsequent scaling and root planing teaching assessments. Second, teaching efficiency is low: The complete application process for a single tooth model takes 15-20 minutes. If multiple sets of comparison models need to be prepared or repeated training is required, the overall teaching cycle will be significantly extended. Summary of the Invention
[0003] The purpose of this invention is to provide a tool for quantitative and uniform application of artificial calculus in a periodontal disease model for oral teaching, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a quantitative and uniform coating tool for artificial calculus in a periodontal disease model for oral teaching, comprising a storage tube, one end of which is an open structure for filling with calculus material, and a guide tube detachably connected to the other end of which a coating head is connected to the end of the guide tube; The coating head is a hollow slender column structure. The upper end of the coating head is a closed structure, and the lower end gradually tapers to form a fine tip. The end of the fine tip has a discharge port. The fine tip is used to be embedded in the subgingival position of the periodontal model. The coating head has a narrow discharge port with a strip structure on its radial outer wall, and the narrow discharge port is located close to the fine end; A pusher is used to push the pebbles in the storage tube to the guide tube.
[0005] In a further embodiment, the other end of the storage tube is provided with a connector, and the end of the guide tube away from the paint head is connected to a docking seat, and the docking seat is axially provided with a threaded hole that is threadedly connected to the connector.
[0006] In a further embodiment, the height of the discharge orifice is 5-7 mm, and the opening width is 1-2 mm.
[0007] In a further embodiment, the feed tube is connected to the paint head near one end of the paint head's closed structure; The coating head is inclined relative to the guide tube, and the angle between the coating head and the guide tube is 120-150°.
[0008] In a further embodiment, an insertion hole is provided at the edge of the closed structure of the coating head. The insertion hole is located on the same side as the narrow outlet. A baffle plate is slidably inserted into the insertion hole. The bottom end of the baffle plate extends into the coating head and is used to block the narrow outlet, thereby adjusting the discharge range of the narrow outlet.
[0009] In a further embodiment, the discharge narrow opening has a longitudinal section, and the longitudinal section is 2mm away from the radial outer wall of the coating head.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] This embodiment provides a tool for quantitative and uniform application of artificial calculus in a periodontal disease model for oral teaching. It includes a storage tube 1, one end of which is open for filling with calculus material, and a pusher for pushing the calculus material from the storage tube 1 to a guide tube 31. Specifically, as... Figure 1 and Figure 2 As shown, the pusher includes a push rod 2 and a rubber plug 25 fixed to the end of the push rod 2. The outer radial wall of the rubber plug 25 slides against the inner radial side wall of the storage tube 1. The other end of the push rod 2 extends out of the opening structure of the storage tube 1 and is fixed with a connecting plate 21.
[0018] Meanwhile, connecting rods 22 are fixed at both ends of the bottom wall of the connecting plate 21, located on both sides of the storage tube 1. A guide ring 23 is fixed between the ends of the two connecting rods 22 and slides against the outer wall of the storage tube 1. A second handle 24 is fixed to the radial side wall of the guide ring 23. A first handle 11 is fixed to the radial outer wall of the end of the storage tube 1 away from the opening structure. A finger ring 12 is fixed to the bottom wall of the first handle 11.
[0019] The other end of the storage pipe 1 is detachably connected to a guide pipe 31, specifically, as follows: Figure 3 As shown, the other end of the storage pipe 1 is provided with a connector 13, and the end of the guide pipe 31 away from the paint head 4 is connected to a docking seat 3. The docking seat 3 has a threaded hole that is threadedly connected to the connector 13 in the axial direction.
[0020] The end of the feed tube 31 is connected to a paint head 4, such as Figure 4As shown, the connection between the feed tube 31 and the paint head 4 is located near one end of the closed structure of the paint head 4. The paint head 4 is inclined relative to the feed tube 31, and the included angle between the paint head 4 and the feed tube 31 is 120-150°.
[0021] Meanwhile, the coating head 4 is a hollow slender column structure. The upper end of the coating head 4 is a closed structure, and the bottom end gradually tapers to form a fine head. The end of the fine head has a discharge port, and the fine head is used to embed into the subgingival position of the periodontal model.
[0022] The coating head 4 has a narrow, strip-shaped discharge port on its radial outer wall, positioned close to the narrow end; for example... Figure 1 and Figure 4 As shown, the hollow, slender cylindrical coating head 4 can be pushed horizontally along the tooth surface during coating, ensuring that the material from the narrow outlet is evenly coated on the periodontal surface. Furthermore, the hollow, slender cylindrical coating head 4 can also be vertically inserted into the gaps between adjacent teeth for coating operations, ensuring thorough coating of tartar. The height of the narrow outlet is 5-7 mm, the opening width is 1-2 mm, and the opening has a longitudinal section. The lateral distance between the longitudinal section and the radial outer wall of the coating head 4 is 2 mm. This design aims to move the radial outer wall of the coating head 4 against the periodontal model surface, with the 2 mm distance between the narrow outlet opening and the tooth surface, thus ensuring uniform coating thickness.
[0023] like Figure 2 , Figure 5 and Figure 6 As shown, a hole 42 is provided at the edge of the closed structure of the paint head 4. The hole 42 is located on the same side as the discharge narrow opening. A baffle plate 41 is slidably inserted into the hole 42. The bottom end of the baffle plate 41 extends into the paint head 4 and is used to block the discharge narrow opening, thereby adjusting the discharge range of the discharge narrow opening.
[0024] Tool assembly: First, connect the docking seat 3 at one end of the guide tube 31 to the connector 13 at the other end of the storage tube 1 with threads to ensure a tight connection and prevent leakage of the padding material.
[0025] Then connect the coating head 4 to the end of the guide tube 31 away from the docking seat 3, so that the connection position is close to the end of the closed structure of the coating head 4. At this time, the included angle between the coating head 4 and the guide tube 31 is 120-150°, with the optimal angle preferably being 120°, which is convenient for the operator to hold and adapt to the coating needs of periodontal models at different angles.
[0026] If it is necessary to adjust the discharge range of the narrow discharge opening, insert the baffle plate 41 into the insertion hole 42 on the edge of the closed structure of the coating head 4, and slide the baffle plate 41 as needed so that its bottom end extends into the coating head 4, blocking part of the narrow discharge opening. Adjusting the discharge range further enhances the flexibility of operation, allowing the operator to flexibly control the coating area and shape of the dental calculus material according to actual teaching needs, meeting diverse teaching scenarios.
[0027] Artificial stone filling: Open the opening at one end of storage tube 1 and slowly fill the prepared artificial stone into storage tube 1, taking care to avoid air mixing into the artificial stone to prevent affecting the coating effect. After filling, ensure that the surface of the artificial stone in storage tube 1 is flat and free of air bubbles.
[0028] Coating operation: The operator holds the finger ring 12 on the handle 11 fixed to the radial outer wall of the end of the storage tube 1 away from the opening structure and the handle 24 fixed to the radial side wall of the guide ring 23 with both hands to keep the tool stable.
[0029] Insert the thin tip of the coating tip 4 into the subgingival position of the periodontal model, aligning the narrow outlet of the coating tip 4 with the area to be coated. Slowly push the connecting plate 21, which causes the push rod 2 and rubber stopper 25 to slide within the storage tube 1, pushing the calculus material from the storage tube 1 to the guide tube 31, and then evenly coating it onto the surface of the periodontal model through the outlet and narrow outlet of the coating tip 4. During the pushing process, carefully control the pushing speed to ensure uniform calculus material distribution. It is important to emphasize that the thin tip at the bottom of the coating tip 4 can be inserted into the subgingival position of the periodontal model for coating, while the narrow outlet is used for supragingival coating. This allows for precise control of the dispensing position, ensuring even distribution of calculus material on the surface of the periodontal model. This effectively avoids the problems of traditional coating methods, providing learners with a more realistic clinical experience and improving teaching quality.
[0030] Depending on the different parts of the periodontal model and the coating requirements, the angle and position of the tool are adjusted in a timely manner to ensure that the coating head 4 can accurately cover the target area and achieve uniform coating. For example, when coating the adjacent surface area, the operator holds handle 11 and handle 24 and adjusts the coating orientation of the coating head 4 so that the coating head 4 can better conform to the shape of the adjacent surface and ensure uniform coating.
[0031] Once the calculus material in the storage tube 1 is used up or the coating operation is completed, remove the tool from the periodontal model. Disassemble the feed tube 31 and the coating head 4, and clean and disinfect the tool for next use. During cleaning, rinse the storage tube 1, feed tube 31, and coating head 4 with clean water to remove any residual calculus material, and then disinfect them with disinfectant to ensure the tool is clean and hygienic.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
