Description

Technical Field

[0001] This utility model relates to oral medical devices, specifically to a personalized cyst plugging device. Background Technology

[0002] Jawbone cysts are cystic lesions that occur within the jawbone, usually related to tooth or jawbone development and inflammation. The incidence is relatively high, especially among adolescents and young adults. While the age range of onset is wide, it is most common in young adults, with a slightly higher incidence in men than women. Jawbone cysts can occur anywhere in the jawbone, but different types have specific predilection areas. Early symptoms of jawbone cysts are not obvious; as the cyst enlarges, it may cause jawbone bulging, facial deformities, tooth loosening or displacement, and other symptoms. Treatment for jawbone cysts mainly includes surgical curettage, cyst decompression and reconstruction, partial jawbone resection, aspiration and drainage, and drug therapy. The specific choice depends on the size, location, type of the cyst, and the individual patient's condition.

[0003] Cyst plugs are mainly used in fenestration decompression surgery for jaw cysts, and are applicable in the following situations:

[0004] 1. Large cyst size: When the cyst diameter exceeds 3.5cm and involves important anatomical structures.

[0005] 2. High surgical risk: The cyst is located in a critical area of ​​the jawbone, such as near the mandibular canal or maxillary sinus. Direct removal may lead to serious complications.

[0006] 3. Patients who cannot tolerate surgery: For children or patients with poor physical condition, fenestration decompression combined with cyst plugging is a more conservative treatment option.

[0007] 4. Cyst recurrence or after multiple surgeries: For recurrent cysts, especially keratotic cysts, fenestration decompression combined with cyst plugging can reduce the risk of recurrence.

[0008] Traditional cyst plugging devices have some limitations and drawbacks in the treatment of jaw cysts. The main issues are as follows:

[0009] 1. Material and processing technology issues

[0010] High material hardness: Traditional cyst plugs are mostly made of hard materials such as polymethyl methacrylate, which are relatively hard and can easily cause pressure and pain on the mucosa.

[0011] Complex processing: The manufacturing process is similar to that of removable partial dentures, requiring the dentures to be sent to a processing plant for completion. The processing cycle is relatively long, which may lead to changes in the mucosa of the surgical area and affect the fit of the cyst plug.

[0012] Difficult to clean: Some materials (such as silicone rubber) have many pores on their surface, making them difficult to polish and clean, and they are prone to bacterial plaque buildup.

[0013] 2. Poor wearing comfort

[0014] Strong foreign body sensation: Traditional cyst plugs are relatively large, and the foreign body sensation is obvious when wearing them, affecting the patient's comfort.

[0015] Interference with chewing: Due to the hardness and large size of the material, it may interfere with chewing movements and even induce or aggravate temporomandibular joint disorders.

[0016] 3. Poor retention effect

[0017] Reliance on natural teeth: Traditional cyst fixation appliances usually require the use of remaining natural teeth for retention, which is not ideal for patients with missing teeth or in the mixed dentition stage.

[0018] Easy to shift or fall off: The simplified cyst plug is fixed by the clamping force of the labial and buccal muscles, which cannot achieve the desired effect.

[0019] 4. Risk of mucosal damage

[0020] Compression of mucous membranes: Hard materials can easily cause localized pressure on the mucous membranes during use, leading to mucous membrane pain.

[0021] Gum recession: Long-term use may cause red and swollen gums, eventually leading to gum recession.

[0022] 5. Difficult to clean and maintain

[0023] Food impaction: Traditional cyst plugs tend to accumulate food residue, increasing the difficulty of cleaning.

[0024] Inconvenient flushing: Some designs lack drainage holes, making flushing the cyst cavity complicated.

[0025] 6. Unable to adjust

[0026] Fixed shape: Once some traditional cyst plugs (such as silicone rubber direct molding) are fixed in shape, they cannot be adjusted according to changes in the cyst cavity.

[0027] 7. Low patient compliance

[0028] Discomfort during wear: Due to the strong foreign body sensation and discomfort during wear, patients have low compliance, which may affect the treatment effect.

[0029] 8. Risk of complications

[0030] Infection risk: Traditional cyst plugging devices can easily lead to cyst cavity infection if not cleaned properly.

[0031] Risk of recurrence: If the cyst plugging device cannot effectively maintain the patency of the cyst cavity, it may lead to cyst recurrence.

[0032] 9. Requires multiple medical visits

[0033] The endoscopic device cannot be inserted on the day of surgery. An impression needs to be taken after surgery to await processing. The patient must schedule another appointment at the hospital after the endoscopic device is manufactured so that it can be inserted. During this process, the size of the surgical incision may change.

[0034] With the development of technology, personalized cyst plugging devices are gradually being used, which can better adapt to the individual needs of patients and reduce the occurrence of the above-mentioned problems. Utility Model Content

[0035] To address the aforementioned problems in existing technologies, this utility model proposes a personalized cyst plugging device. The aim is to provide a cyst plugging device that features a short manufacturing cycle, comfortable wear, good retention, convenient cleaning and maintenance, high patient compliance, and low risk of complications, thereby improving treatment outcomes and reducing the number of hospital visits. The specific solution is as follows:

[0036] A personalized cyst plugging device, comprising an irrigation tube, a retention foot, and an end cap, wherein the irrigation tube is integrally formed with at least one of the retention feet; wherein...

[0037] One end of the flushing tube extends into the cyst cavity through a cyst opening, while the other end is located in the labial space and is movably connected to a sealing end cap.

[0038] One end of the retention foot is fixedly connected to the outer diameter of the flushing tube, and the other end of the retention foot is provided with a flat adhesive base plate. One side end face of the adhesive base plate is provided with a retention base mesh structure for bonding and fixing to the outer surface of the upper teeth.

[0039] Furthermore, the outer diameter of the rinsing tube is connected to two retaining feet arranged in an inverted "V" shape. The other ends of the two retaining feet are respectively bonded and fixed to two spaced upper teeth, with one or two upper teeth spaced apart between the two upper teeth.

[0040] Furthermore, the sealing end cap is made of PEEK material, polymer resin material, or rubber.

[0041] Furthermore, the outer surface of the sealing end cap is integrally formed with a flexible connecting part, and the end of the flexible connecting part is snapped into the outer diameter of the flushing pipe.

[0042] Furthermore, the inner end face of the sealing end cap is provided with an annular groove that snaps into the other end of the flushing pipe.

[0043] Furthermore, the inner end face of the sealing end cap is provided with a cylindrical plug, which is interference-fitted with the inner wall of the flushing pipe.

[0044] Furthermore, the retaining foot is slender and rod-shaped, the width of the bonding base plate is greater than the width of the retaining foot, and the width of the bonding base plate is not less than 2 / 3 of the width of the upper tooth.

[0045] Furthermore, the retaining bottom mesh structure is a honeycomb or mesh structure.

[0046] Furthermore, the bonding end face of the bonding base plate is a curved surface that fits against the outer surface of the upper tooth.

[0047] Furthermore, the flushing pipe, the retaining foot, the adhesive base plate, and the retaining bottom mesh structure are digitally designed and 3D printed as a single unit.

[0048] This utility model designs a personalized cyst plugging device, aiming to solve many problems existing in traditional cyst plugging devices. Its advantages are:

[0049] 1) The irrigation tube and retention base are 3D printed in one piece, achieving precise manufacturing and high integration of the irrigation tube and retention base. This design not only improves the overall strength and stability of the cyst plugging device, but also ensures its precise fit in the oral environment, effectively reducing the risk of patient discomfort and complications caused by fit problems.

[0050] 2) The retention base features a widened adhesive base plate with a retention mesh structure. This design enhances the bonding area and strength between the appliance and the upper teeth, maintaining good retention even during oral activities such as chewing, reducing the risk of displacement or dislodgement. The retention mesh structure further improves the stability and uniformity of the bonding, ensuring the appliance fits tightly against the outer surface of the upper teeth. Furthermore, the widened adhesive base plate design facilitates the dentist's operation, improving the precision and efficiency of the procedure.

[0051] 3) The irrigation tube has a movable end cap at its outer end. This end cap design allows the irrigation tube to remain sealed when irrigation is not needed, effectively preventing food residue and bacteria from entering the cyst cavity and reducing the risk of infection. At the same time, the movable design of the end cap also makes it easy for patients to open it for cyst cavity irrigation when needed, making the operation simple and convenient.

[0061] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0062] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0063] Example 1

[0064] Reference Figure 1-6 As shown, this utility model provides a personalized cyst plugging device, which consists of an irrigation tube 10, a retaining foot 20, and an end cap 30.

[0065] The device is installed inside the oral cavity. One end of the irrigation tube 10 extends into the cyst cavity through a surgical window for the cyst, while the other end is located in the labial space and is movably connected to a sealing end cap 30. One end of the retention foot 20 is integrally fixed to the outer diameter of the irrigation tube 10, and the other end of the retention foot 20 is provided with a flat adhesive base plate 21. One end face of the adhesive base plate 21 is provided with a retention base mesh structure 22 for bonding and fixing to the outer surface of the upper teeth.

[0066] Among them, the irrigation tube 10, the retention foot 20, the bonding base plate 21, and the retention base mesh structure 22 are digitally designed and 3D printed in one piece. The digital personalized design ensures that the cyst plugging device is highly matched with the patient's oral cavity structure, while effectively ensuring the strength of the plugging device.

[0067] In use, the irrigation tube 10 is first inserted into the cyst cavity through a surgical window incision. Then, a light-cured adhesive (e.g., photosensitive resin) is applied to the bonding surface. Next, the retention mesh structure 22 on the inner side of the bonding base plate 21 is attached to the surface of the light-cured adhesive. The position of the irrigation tube 10 is adjusted, and then light curing is performed to bond the bonding base plate 21 to the outer surface of the upper tooth. This invention provides stable retention force for the cyst fixation device through the tooth. The design of the retention foot 20 allows the cyst fixation device to fit tightly against the tooth surface. Simultaneously, the flat bonding base plate 21 increases the contact area with the tooth, further improving the retention effect. Furthermore, the bonding base plate 21 is fixed with a light-cured adhesive, which not only provides strong retention but also cures quickly, is easy to operate, and significantly shortens the patient's treatment time.

[0068] In this embodiment, the flushing pipe 10 is connected to two retaining feet 20 arranged in an inverted "V" shape, such as... Figure 6 As shown, the other ends of the two retention feet 20 are respectively bonded and fixed to two spaced upper teeth, leaving one tooth between them. The two retention feet 20 form a triangular support, enhancing the stability and retention of the cyst plug. Simultaneously, a certain distance is maintained between the ends of the two retention feet 20, allowing them to be bonded and fixed to the tooth surfaces of the two spaced upper teeth. This prevents the bases of the two retention feet 20 from being too close together, which would affect the retention effect and makes the triangular support more stable.

[0069] In this embodiment, the sealing end cap 30 is made of PEEK (polyetheretherketone), polymer resin, or rubber. These materials all possess the following advantages: 1) They have good biocompatibility and corrosion resistance, effectively reducing irritation and damage to the patient's oral mucosa. 2) They are easy to process and mold, meeting the needs of personalized customization, improving retention and wearing comfort.

[0070] In this embodiment, a flexible connecting part 31 is integrally formed on the outer surface of the sealing end cap 30. The end of the flexible connecting part 31 is provided with a snap-fit ​​protrusion 32. The outer diameter of the other end of the flushing pipe 10 is provided with a snap-fit ​​structure located on the lip side. The snap-fit ​​structure is provided with a snap-fit ​​groove. The snap-fit ​​protrusion 32 of the flexible connecting part 31 is embedded in the snap-fit ​​groove to realize the movable connection between the sealing end cap 30 and the flushing pipe 10. On the one hand, the sealing end cap 30 can be fastened to the end face of the flushing pipe 10. On the other hand, it can also prevent the sealing end cap 30 from falling off the flushing pipe 10.

[0071] In another embodiment, the flushing pipe 10 and the sealing end cap 30 can also be rotatably connected by a rotating shaft provided on the flushing pipe 10.

[0072] In this embodiment, the inner end face of the sealing end cap 30 is provided with an annular groove 33 that is snapped into the other end of the flushing pipe 10. The end face of the flushing pipe 10 is snapped into the annular groove 33 so that the sealing end cap 30 is sealed and snapped onto the end face of the flushing pipe 10.

[0073] In this embodiment, the retention foot 20 is a slender rod shape, and the width of the bonding base plate 21 is greater than the width of the retention foot 20, and the width of the bonding base plate 21 is not less than 2 / 3 of the width of the currently connected upper tooth. This reduces the amount of material used and minimizes the foreign body sensation. At the same time, the bonding base plate 21 is wide enough to ensure sufficient bonding area between the bonding base plate 21 and the tooth surface, ensuring that the bonding base plate 21 can be firmly bonded to the outer surface of the upper tooth, further improving the retention effect of the cyst fixation device.

[0074] In this embodiment, the bonding end face of the bonding base plate 21 is a curved surface that fits against the outer surface of the upper tooth to improve the strength and stability of the bond. The curved surface design can better adapt to the natural shape of the outer surface of the tooth, reducing the problem of loose bonding caused by shape mismatch, thereby enhancing the retention effect of the cyst tampon. To ensure the retention effect of the bonding base plate 21, the retention base mesh structure on the inner end face of the bonding base plate 21 is a honeycomb or mesh structure. This structure can increase the bonding area, improve the bonding strength, and ensure that the cyst tampon is not easily detached during use. In addition, the design of the retention base mesh structure also facilitates the penetration of resin adhesive material, forming a more solid bonding effect.

[0075] Example 2

[0076] As a second embodiment of this utility model, the difference between this embodiment and the first embodiment lies only in the different ways the sealing end cap 30 and the flushing pipe 10 are connected. Figure 8 As shown, in this embodiment, the inner end face of the sealing end cap 30 is provided with a columnar plug 34, which is interference-fitted with the wall of the flushing pipe 10. By inserting the columnar plug 34 into the flushing pipe 10, the sealing end cap 30 is sealed and fastened to the end face of the flushing pipe 10.
