Description

Technical Field

[0001] This utility model belongs to the field of oral medicine technology, specifically relating to a novel cyst plug. Background Technology

[0002] Jawbone cysts are a common disease in oral and maxillofacial surgery. Postoperative fenestration and drainage are crucial steps in the treatment of large jawbone cysts. In this process, the cyst plug is the core device for maintaining the ostomy opening and ensuring continuous drainage of the cyst cavity.

[0003] Currently, the main clinical applications of cyst plugs are denture-type plugs and 3D-printed cyst plugs designed and manufactured digitally. Denture-type plugs are typically made of acrylic resin, and their design usually includes a resin protrusion that extends into the cyst cavity and a base that covers the dentition and gums. Some improved designs also include a drainage tube installed within the resin protrusion. 3D-printed cyst plugs, on the other hand, utilize digital technologies (such as oral scanning and CAD design) to generate a cyst cavity model, and then print it using materials such as light-cured resin.

[0004] The manufacturing process is complex and carries risks of trauma: Impressions of denture-type cyst plugs need to be taken after the initial healing of the postoperative wound. There is a risk of impression material spilling into the cyst cavity during impression taking, and for patients experiencing postoperative pain or limited mouth opening, the procedure is difficult, potentially delaying treatment or causing secondary trauma. During trial fitting, adjustments are often required due to incomplete soft tissue stabilization, increasing the number of patient visits. Furthermore, denture-type cyst plugs are bulky, with a base and clasps, causing a strong foreign body sensation and significantly interfering with the patient's speech and chewing functions. The edges of the base and resin protrusions can easily compress tissues, causing pain or ulcers. The materials used in 3D-printed cyst plugs may yellow, become brittle, age, or break after long-term use in the oral environment, making it difficult to guarantee comfort and reliability, severely impacting treatment effectiveness and patient experience. Utility Model Content

[0005] To solve the above problems, the present invention adopts the following technical solution: A novel cyst plug, comprising: A drainage tube, the surface of which is provided with multiple drainage holes for insertion into the cyst cavity for drainage; A closed drainage film is placed at one end of the drainage tube and tightly adhered to the oral mucosa on the surface of the cyst to prevent drainage material from leaking into the oral cavity. A retainer, wherein the retainer is disposed on the tooth surface inside the oral cavity; A metal wire, one end of which passes through the sealed drainage patch and is connected to the drainage tube, and the other end extends to the outside of the oral cavity and is connected to the retainer, which is used to fix the metal wire in place.

[0006] Furthermore, the surface of the end of the drainage tube away from the closed drainage patch is also provided with a biomimetic spiral structure for anchoring within the cystic tissue.

[0007] Furthermore, the biomimetic spiral structure is a continuous spiral protrusion or thread structure, used to enhance the mechanical anchoring force of the drainage tube within the cyst cavity.

[0008] Furthermore, the drainage holes are not uniformly distributed along the axial direction of the drainage tube, and the distribution density is higher at the end of the drainage tube away from the sealed drainage film than at the end of the drainage tube near the sealed drainage film, and is distributed within the groove of the biomimetic spiral structure.

[0009] Furthermore, the closed drainage patch includes a medical adhesive dressing layer, a flexible drainage channel, and a sealed collection sac; The dressing layer is made of medical pressure-sensitive adhesive material, which can adhere tightly to the oral mucosa on the surface of the cyst, avoiding gaps at the dressing site that could lead to leakage of drainage. One end of the flexible drainage channel passes through the center of the dressing layer and communicates with the drainage tube, while the other end is connected to the sealed collection sac; wherein the sealed collection sac is detachably disposed on the side of the dressing layer away from the cyst.

[0010] Furthermore, the drainage tube is made of a flexible and biocompatible medical polymer material.

[0011] Furthermore, the retainer is an orthodontic bracket, and the groove of the bracket is used to fix the metal wire.

[0012] Furthermore, the retainer can also be a denture base or a bone screw.

[0013] Beneficial effects: This invention features a unique biomimetic spiral anchoring structure that not only provides stability, but also, through the combination of its spiral grooves and non-uniformly distributed drainage holes, forms a highly efficient three-dimensional drainage network, ensuring smooth drainage of cyst fluid (especially deep cyst fluid) without any drainage dead zones. Simultaneously, this design facilitates the injection of irrigation fluid deep into the cyst cavity through the drainage tube, achieving thorough flushing of the entire cyst cavity, completely removing pus and necrotic tissue, and greatly reducing the risk of secondary infection. The biomimetic spiral structure, through mechanical anchoring, fits into the cyst wall tissue, providing excellent initial stability and effectively preventing early dislodgement. The external retainer provides strong and stable final retention force through the teeth, avoiding the loosening, pressure pain, and difficulty in insertion and removal caused by traditional cyst plugs that rely on soft tissue undercuts or clasps for retention. This invention is compact, causes no foreign body sensation, has minimal impact on the patient's speech and chewing function, and offers far superior comfort compared to traditional large denture-style cyst plugs.

[0014] This invention utilizes the characteristics of orthodontic brackets and flexible metal wires. During the long healing process, which can last for several years, doctors do not need to re-fabricate the cyst plug. They only need to adjust the length and bending angle of the wire extending outside the mouth during follow-up visits to ensure the drainage end maintains the optimal relative position with the changing cyst shape, ensuring continuous and effective drainage. This dynamic adaptation capability is completely lacking in traditional fixed cyst plugs, truly achieving "one device for the entire treatment process."

[0015] This invention features a sealed drainage film that directly drains the drainage fluid to the outside of the mouth for collection, completely avoiding the problems of drainage fluid contaminating the oral environment, causing nausea and discomfort to patients, or secondary infection.

[0016] This invention eliminates the need for traditional impression taking during the postoperative sensitive period, avoiding related risks. Data can be acquired using digital intraoral scanning, making the design and manufacturing process more precise and efficient. The orthodontic brackets and stainless steel wires used are all commonly used and inexpensive consumables in dental clinics, resulting in extremely low costs and significantly reducing the economic burden on patients, making this high-quality treatment solution more accessible and worthy of widespread adoption.
