Description

Technical Field

[0001] This invention relates to the field of dental periodontal treatment instruments, and more specifically, to a double-layer cleaning and scaling component adapted to the gingiva. Background Technology

[0002] Patients with periodontitis and gingivitis have both hard tartar from the tooth roots and bacterial biofilm on the surface of the gums attached to their periodontal pockets. Traditional clinical scaling methods mainly rely on two types of instruments: ultrasonic scalers and manual scalers. Conventional scalers are only equipped with a single hard blade structure, which makes direct hard contact with the gums and tooth structure during operation. Most scaling instruments on the market with soft outer layers have a smooth flat design, which can only perform simple wiping operations and do not have a structure to specifically remove biofilm. Clinical cleaning solutions are mostly applied by local irrigation with syringes. The instruments themselves do not have the function of storing and releasing liquid simultaneously. The supply of liquid solution and the scaling action are separated. It requires the medical staff to use both hands to complete the irrigation and scaling steps, making the overall operation process cumbersome.

[0003] However, the periodontal pocket has a narrow internal space and the soft gingival tissue is easily damaged. Existing periodontal scaling instruments are mostly single hard blades, which usually cannot simultaneously perform root root hard tissue scaling and non-invasive cleaning of gingival soft tissue. This leads to problems such as gingival stinging and bleeding and incomplete removal of thin biofilm during the scaling process. It is impossible to carry out a full-area synchronous integrated cleaning operation of the periodontal pocket, which affects the efficiency of periodontal treatment and patient comfort. Therefore, we have made improvements to this and proposed a double-layer cleaning and scaling component adapted to the gingiva. Summary of the Invention

[0004] In view of the above-mentioned problems in the existing technology, the purpose of the present invention is to provide a double-layer cleaning and scaling component adapted to the gums.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: a double... The cleaning and scaling component includes a support component for handheld gripping, a plurality of cushioning components for elastic buffering on one side of the support component, an outer layer component for conforming to the inner wall of the periodontal pocket and peeling off the bacterial biofilm on the surface of the gingiva on one end of the side of the cushioning component away from the support component, a cleaning component for storing antibacterial care solution and for contact-type squeeze-driven controllable spraying to wet and loosen plaque biofilm on the other end of the side of the outer layer component away from the cushioning component, and an inner layer component for scraping deep into the periodontal pocket to remove tartar on the root surface and deep subgingival plaque.

[0006] Preferably, the support assembly includes a support handle, and a support block is fixedly connected to the side of the support handle near the buffer assembly.

[0007] Preferably, the outer layer component includes a flexible outer layer body, which is fixedly connected to one end of the buffer component away from the support component, and a plurality of protrusions are fixedly connected to the outer side of the flexible outer layer body.

[0008] Preferably, a groove 1 is provided between adjacent protrusions, and a plurality of groove 1 are provided on the outer side of the flexible outer layer body, and a plurality of groove 2 are provided inside the flexible outer layer body.

[0009] Preferably, the cleaning component includes a plurality of storage boxes, which are respectively fixedly connected inside the plurality of grooves, and storage caps are snapped onto both ends of the plurality of storage boxes.

[0010] Preferably, each of the storage boxes has a liquid outlet channel fixedly connected to its upper end, and each of the liquid outlet channels penetrates the interior of the storage box and the flexible outer body to its outer side. Each of the liquid outlet channels has a liquid outlet nozzle fixedly connected to its upper end, and each of the storage boxes has a piston plate slidably connected to its interior.

[0011] Preferably, the lower ends of the piston plates are all fixedly connected to a connecting shaft, and the connecting shafts extend through the interior of the storage box to its lower part, and the lower ends of the connecting shafts are all fixedly connected to a flexible pressing block.

[0012] Preferably, the inner layer assembly includes an inner layer body, which is fixedly connected to one side of the flexible outer layer body, and a plurality of cleaning blades are fixedly connected to the side of the inner layer body away from the flexible outer layer body.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention innovatively sets up a buffer component that works in synergy with an outer component featuring a textured surface. The buffer component forms an elastic isolation buffer layer that can absorb the rigid impact force during the cleaning process, preventing the inner hard cleaning blade from directly contacting the gums and teeth. This solves the problem of traditional scaling instruments causing tooth sensitivity, gum congestion, inflammation, and damage due to hard contact. The outer component has an integrally formed protrusion and groove friction structure on the flexible outer body surface. It relies on micro-shearing action to peel off the thin layer of bacterial biofilm on the surface of the gums layer by layer. This overcomes the industry shortcoming of commercially available cleaning tools that can only wipe and cannot thoroughly remove hidden biofilms in soft tissues, achieving non-invasive deep cleaning of the gum soft tissue.

[0014] 2. This invention integrates a cleaning component with a built-in liquid storage function and an inner scraping structure. The cleaning component has a built-in refillable sealed storage box and a linked piston spraying structure. It automatically releases antibacterial liquid based on the periodontal pocket adhesion pressure. The liquid pre-dissolves and softens plaque, reducing peeling resistance. No external water supply line is required, and the disassembly and replacement of the care solution is convenient. The inner component is equipped with a hard cleaning blade to simultaneously scrape away tartar and deep subgingival plaque deep in the tooth root. The entire set of components can simultaneously complete the biological cleaning of the gingival soft tissue and the hard tissue scraping of the tooth root, making up for the functional deficiencies of traditional scaling instruments that can only clean tartar and ignore the biofilm on the gingival surface, and greatly improving the efficiency of deep integrated cleaning of the periodontal pocket.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0018] Please refer to Figure 1- Figure 6As shown, the present invention provides a technical solution: a double-layer cleaning and scaling component adapted to the gums, including a support component 1 for hand-held gripping, a plurality of buffer components 2 for elastic cushioning on one side of the support component 1, an outer layer component 3 for conforming to the inner wall of the periodontal pocket and peeling off the bacterial biofilm on the surface of the gums on one end of the side of the buffer component 2 away from the support component 1, a cleaning component 4 for storing antibacterial care solution and for contact-type squeeze-driven controllable spraying to wet and loosen plaque biofilm on the other end of the side of the buffer component 2, and an inner layer component 5 for scraping deep into the periodontal pocket to remove tartar on the root surface and deep subgingival plaque on the side of the outer layer component 3 away from the buffer component 2. In the preferred embodiment of this technical solution, please refer to Figure 2 As shown, the support assembly 1 includes a support handle 101, and a support block 102 is fixedly connected to the side of the support handle 101 near the buffer assembly 2.

[0019] Furthermore, the support component 1 includes a support handle 101 and a support block 102. Medical personnel hold the support handle 101 and insert the working end of the component into the patient's periodontal pocket. The support block 102 serves as a load-bearing base, uniformly fixing the buffer component 2, outer layer component 3, inner layer component 5, and cleaning component 4, achieving integrated assembly of all functional structures. The buffer component 2, outer layer component 3, cleaning component 4, and inner layer component 5 are all equipped with multiple modular units, allowing the number of assembly units to be adjusted as needed according to the scope of periodontal treatment and the size of the periodontal pocket.

[0020] In the preferred embodiment of this technical solution, please refer to Figures 3-4 As shown, the outer component 3 includes a flexible outer body 301, which is fixedly connected to one end of the buffer component 2 away from the support component 1. Several protrusions 302 are fixedly connected to the outer side of the flexible outer body 301.

[0021] Furthermore, the buffer component 2 is integrally molded from high-elasticity medical-grade silicone. The entire component is arranged in a ring-shaped column array and uniformly assembled between the support block 102 and the front-end cleaning structure to form a flexible buffer isolation layer. The overall structure has good deformation and rebound capabilities. When the front end of the component extends into the periodontal pocket and comes into contact with the teeth and gums, the buffer component 2 can quickly compress and deform, fully absorbing the rigid impact force generated by the collision of hard components. This isolates the inner component 5, the hard cleaning blade 502, and the metal substrate from direct hard contact with the tooth and gum soft tissue, significantly reducing the mechanical stimulation caused by hard scraping and avoiding obvious soreness, stinging, and discomfort for the patient. At the same time, the buffer component 2 can disperse local concentrated pressure, preventing excessive local pressure from continuously compressing the gums. This effectively reduces congestion, swelling, inflammation, and even bleeding caused by external pressure and friction on the gums, providing a protective buffer for the periodontal soft tissue throughout the process.

[0022] In the preferred embodiment of this technical solution, please refer to Figures 3-4 As shown, a groove 303 is provided between adjacent protrusions 302, and several grooves 303 are provided on the outside of the flexible outer body 301. Several grooves 304 are provided inside the flexible outer body 301.

[0023] Furthermore, the flexible outer layer 301 is integrally molded from a medical-grade soft elastic material, with hemispherical protrusions 302 and concave grooves 303 evenly and alternately arranged on its outer surface, forming a continuous undulating structure. The device combines a non-smooth friction interface; when it extends into the periodontal pocket and adheres to the gingival surface for cleaning, the raised bumps 302 can form dense micro-shearing contacts, precisely wedging into the adhesion gaps between the bacterial biofilm and the gingival epithelium, while the grooves 303 can accommodate the detached biofilm debris. At the same time, in conjunction with the bumps 302, they form an intermittent friction and squeezing effect. The synergistic effect of the two can continuously destroy the extracellular polysaccharide binding matrix inside the biofilm, disintegrate the overall adhesion structure of the biofilm, and break down and peel off the stubborn thin biofilm attached to the surface of the gingival soft tissue layer by layer and piece by piece. This effectively solves the problem that smooth soft surfaces can only be simply wiped and cannot completely remove hidden thin biofilms.

[0024] In the preferred embodiment of this technical solution, please refer to Figure 5 As shown, the cleaning component 4 includes several storage boxes 401, which are fixedly connected to the inside of several grooves 304, and storage covers 402 are snapped onto both ends of the storage boxes 401.

[0025] Furthermore, both ends of the storage box 401 are equipped with detachable storage caps 402. An elastic sealing ring is set around the inside of the storage cap 402, and the cap body and the end of the storage box 401 are connected by an interference fit. Before the operation, medical staff can directly pull open the storage caps 402 on both sides and add antibacterial cleaning solution into the inner cavity of the storage box 401 through the openings at both ends. The double opening design at both ends can speed up the replenishment speed and reduce residual air bubbles. After filling, the storage caps 402 are pressed and fastened again. The gaps are sealed by the inner sealing ring to form a sealed liquid storage cavity, which effectively prevents the cleaning solution from leaking or being lost prematurely during the operation. Medical staff can change the cleaning solution with different functions such as dissolving biofilm, antibacterial and anti-inflammatory, and soothing gums as needed according to the severity of periodontal inflammation and cleaning needs. No additional tools are required for disassembly, replenishment and replacement of solution. The operation is simple and convenient and suitable for continuous clinical treatment.

[0026] In the preferred embodiment of this technical solution, please refer to Figure 5 As shown, each of the storage boxes 401 has a liquid outlet channel 403 fixedly connected to its upper end, and each of the liquid outlet channels 403 penetrates the interior of the storage box 401 and the flexible outer body 301 to its outer side. Each of the liquid outlet channels 403 has a liquid outlet nozzle 404 fixedly connected to its upper end, and each of the storage boxes 401 has a piston plate 405 slidably connected to its interior.

[0027] Furthermore, the liquid outlet nozzle 404 has a built-in one-way control valve. When there is no liquid pressure, the valve remains closed to prevent leakage of cleaning fluid from the storage box 401. Only when the piston plate 405 pushes the liquid upward to generate pressure, the valve automatically opens, and the cleaning fluid is sprayed out from the liquid outlet nozzle 404 along the liquid outlet channel 403. The cleaning fluid inside the storage box 401 can dissolve and soften the bacterial biofilm, reduce the resistance of the protrusion 302 in peeling off the biofilm, and make the biofilm easier to detach completely.

[0028] In the preferred embodiment of this technical solution, please refer to Figure 5 As shown, the lower ends of several piston plates 405 are fixedly connected to connecting shafts 406, and the connecting shafts 406 extend through the interior of the storage box 401 to its lower part. The lower ends of several connecting shafts 406 are fixedly connected to flexible pressing blocks 407.

[0029] Furthermore, the flexible pressing block 407 fits against the bottom of the periodontal pocket. During the cleaning operation, the soft tissue inside the periodontal pocket squeezes the flexible pressing block 407. The pressing block pushes the piston plate 405 upward through the connecting shaft 406. The piston plate 405 squeezes the cleaning fluid inside the storage box 401. Automatic liquid spraying is achieved by relying on the pressure of the periodontal pocket. No external water supply equipment is required. The liquid is released synchronously with the movement of the instrument into the periodontal pocket. A sealing ring is provided on the contact surface between the connecting shaft 406 and the storage box 401 to prevent leakage.

[0030] In the preferred embodiment of this technical solution, please refer to Figure 6 As shown, the inner layer component 5 includes an inner layer body 501, which is fixedly connected to one side of the flexible outer layer body 301. A plurality of cleaning blades 502 are fixedly connected to the side of the inner layer body 501 away from the flexible outer layer body 301.

[0031] Furthermore, the inner body 501 of the inner component 5 is equipped with a hard cleaning blade 502. The cleaning blade 502 fits against the surface of the hard tissue of the tooth root and can scrape away hard deposits such as calcified tartar and stubborn deep dental plaque on the root surface. The flexible outer body 301 of the outer component 3 isolates the cleaning blade 502 from the soft tissue of the gum throughout the process, allowing the cleaning blade 502 to contact the hard tissue of the tooth, avoiding the blade from scratching the gum, and realizing the simultaneous cleaning of the soft tissue of the gum and the hard tissue of the tooth root in separate areas.

[0032] Working principle: Medical staff hold the support handle 101 of the support component 1 and insert the front end of the device into the narrow periodontal pocket. The support block 102 supports the entire front working structure; the buffer component 2 is located on the support block 102. Between the front cleaning structure and the front cleaning structure, it absorbs the rigid impact force generated by the contact between teeth and gums, avoiding toothache and gum inflammation caused by hard contact. The flexible outer body 301 of the outer component 3 is provided with protrusions 302 and grooves 303 to form a concave-convex friction surface, which fits against the surface of the gums and cuts into the bacterial biofilm, directly destroying the adhesion structure between the biofilm and the gingival epithelium, and pre-dispersing the thin biofilm.

[0033] The flexible pressing block 407 at the bottom of the periodontal pocket inner wall squeezing cleaning component 4, driven by the connecting shaft 406, pushes the piston plate 405 upward to squeeze the cleaning fluid in the storage box 401. The liquid pressure opens the liquid nozzle 404 with a built-in one-way valve, and the medicine is sprayed out to dissolve and soften the residual biofilm. The storage box 401 has removable storage caps 402 at both ends, which can be added and replaced with cleaning and care fluid at any time. When working simultaneously, the cleaning blade 502 on the inner body 501 of the inner component 5 fits against the root surface to remove deep plaque and hard tartar from the root. The flexible outer body 301 isolates the blade to protect the gums, completing two cleaning processes in one go: soft tissue biofilm removal and root hard tissue scraping.
