Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a training model for tooth extraction wound curettage that is conducive to intuitively simulating and demonstrating periodontal damage, helps trainees to promptly identify and correct curettage operations, and improves the training effect of curettage operations. Background Technology

[0002] Tooth extraction wound curettage refers to the process of cleaning the alveolar socket with specialized instruments after tooth extraction under local anesthesia. This process removes inflammatory tissue, tooth fragments, bone fragments, granulation tissue, tartar, and other debris to promote wound healing. Removing these tissues reduces local inflammation, helps prevent bacterial infection from remaining tissue, and prevents uncontrolled bleeding or the spread of infection. Tooth extraction wound curettage is crucial for post-extraction recovery and can effectively prevent complications.

[0003] However, there is a lack of teaching models for tooth extraction wound curettage on the market. In teaching, ordinary periodontal models are generally used to remove teeth and then replaced with models for tooth extraction wound curettage, which does not adequately demonstrate the situations encountered during tooth extraction wound curettage, resulting in poor teaching and training effectiveness. A Chinese utility model patent, entitled "A Teaching Model for Periodontal Index Examination," with patent number ZL202223228391.1 and publication date of 2023-06-09, includes a model base with several grooves in which alveolar bone is held. Several teeth are fixedly installed on the alveolar bone, and the gap between the alveolar bone and the neck of the teeth is filled with gingiva. The gingival margin has a 1mm-3mm swollen structure simulating gingivitis, or the gingiva may have different shades depending on the severity of the gingivitis, forming a teaching structure for gingivitis. Several artificial tartar deposits are placed around the gingiva, forming a teaching structure for tartar. A 4mm-9mm pocket-like structure is provided at the junction of the gingiva and the neck of the teeth, forming a teaching structure for periodontal pockets. This teaching model can be used to guide students in visual and probing examinations of the community periodontal index. However, although this patent can simulate periodontium, it cannot effectively demonstrate the condition of the extraction socket after tooth extraction, making it unsuitable for teaching and training in tooth extraction wound curettage.

[0004] How to solve the above problems has become an urgent technical issue. Utility Model Content

[0005] The purpose of this invention is to provide a training model for tooth extraction wound scraping that facilitates intuitive simulation of periodontal damage, helps trainees to promptly identify and correct scraping operations, and improves the training effect of scraping operations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a training model for tooth extraction wound curettage, including a hinged base that can rotate at a certain angle. A pair of model bases symmetrically and detachably mounted on the front end of the hinged base are simulated alveolar bone. A tooth extraction socket is provided on the model base at the position corresponding to a human tooth. A dental model simulating a dental alveolar bone is covered on the outside of the model base. An installation groove is provided on the outer side of the model base corresponding to the human maxillary first molar, which can correspond to and communicate with the bottom of the tooth extraction socket. A maxillary sinus floor mucosa model is detachably mounted in the installation groove. A granulation tissue model is adhered to the bottom of the tooth extraction socket.

[0008] Furthermore, it also includes an adhesive needle capable of attaching the granulation tissue model, with a gripping ball at the rear end of the adhesive needle and a rounded end at the front end of the adhesive needle. An arc-shaped groove is provided around the adhesive needle near the rounded end, and the granulation tissue model is placed at the bottom of the extraction socket corresponding to the first molar, first premolar, and central incisor of the human body.

[0009] Furthermore, the granulation tissue model is a follicle-shaped structure that is thicker at the bottom and thinner at the top, and the granulation tissue model is made of a soft material.

[0010] Furthermore, the maxillary sinus floor mucosa model includes a splint, and a groove is provided on the upper front surface of the splint to communicate with the bottom of the extraction socket. A simulation piece capable of simulating the maxillary sinus floor mucosa is detachably installed in the groove.

[0011] Furthermore, the simulation sheet is made of a tough material.

[0012] Furthermore, the dental model is provided with through holes corresponding to the positions of each extraction socket, and the dental model is made of rubber material.

[0013] Furthermore, the hinge seat includes a pair of symmetrically arranged bases, with one end of the two bases hinged together. A connecting post is provided on the front of each of the two bases, and a limiting block that can cooperate with each other to limit the rotation angle of the bases is provided in the middle of the back of each of the two bases. Pressing blocks are provided at the upper and lower ends of the back of the two bases away from the hinge end.

[0014] Furthermore, a connecting hole is provided on the back of the model base, which can be detachably connected to the connecting column. Both the model base and the hinge seat are made of resin material.

[0015] Due to the adoption of the above structure, the beneficial effects of this utility model are as follows:

[0016] This invention relates to a training model for tooth extraction wound curettage. The model base is symmetrically and detachably mounted on a hinged seat, allowing it to open and close, thus mimicking the opening and closing of the human mouth during training and improving training effectiveness. The jawbone model simulates the jawbone structure, facilitating a more intuitive demonstration of periodontal damage. The granulation tissue model is bonded to the bottom of the extraction socket to simulate the internal condition of the socket after tooth extraction, simplifying fabrication and maintenance and aiding in practice of tooth extraction wound curettage. The maxillary sinus floor mucosa model is detachably mounted in a mounting slot and is connected to the bottom of the extraction socket. When practicing scraping the extraction wound, trainees may scrape against the maxillary sinus floor mucosa model. Since care must be taken to minimize or avoid damaging the maxillary sinus floor mucosa during scraping, the damage to the sinus mucosa model reflects the accuracy of the trainee's scraping technique, serving as a reminder and helping trainees to promptly identify and correct their scraping movements, thus improving the training effect and helping trainees better master the scraping method. Therefore, this utility model, a training model for scraping the extraction wound, provides a visual simulation of periodontal damage, allowing trainees to promptly identify and correct their scraping movements, thereby improving the training effect.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please refer to Figure 1-13This utility model provides a training model for tooth extraction wound scraping, comprising a hinged base 1 capable of rotating at a certain angle; a pair of model bases 2 symmetrically and detachably mounted on the front end of the hinged base 1, simulating alveolar bone; extraction sockets 21 corresponding to human teeth on the model bases 2; a dental model 3 simulating the dental alveolar bone covering the model bases 2; an installation groove 22 corresponding to the bottom of the extraction socket 21 on the outer side of the model base 2; a maxillary sinus floor mucosa model 4 detachably mounted in the installation groove 22; and a granulation tissue model 23 bonded to the bottom of the extraction socket 21. The model bases 2 are symmetrically and detachably mounted on the hinged base 1, allowing them to open and close, thus facilitating the simulation of the opening and closing of the human mouth during training and improving the training effect. The dental model 3 simulates the dental alveolar structure, providing a more intuitive simulation. To demonstrate periodontal damage, a granulation tissue model 23 is bonded to the bottom of the extraction socket 21 to simulate the internal condition of the socket 21 after tooth extraction. This facilitates fabrication and maintenance and allows trainees to practice scraping the extraction wound. A mounting slot 22 is correspondingly located at the bottom of the extraction socket 21, which belongs to the position of the 26th first molar. The maxillary sinus floor mucosa model 4 is detachably installed within the mounting slot 22 and is connected to the bottom of the extraction socket 21. Therefore, trainees can scrape the maxillary sinus floor mucosa model 4 when practicing scraping the extraction wound. Since care must be taken to minimize or avoid scratching the maxillary sinus floor mucosa when scraping the maxillary extraction socket, the damage to the sinus mucosa model 4 reflects the accuracy of the trainee's scraping operation training, serving as a reminder and helping trainees to promptly identify and correct their scraping operations, improving the scraping training effect and helping trainees better master the scraping method.

[0034] This invention also includes an adhesive needle 5 capable of attaching the granulation tissue model 23. A gripping ball 51 is provided at the rear end of the adhesive needle 5, and the front end of the adhesive needle 5 is rounded. An arc-shaped groove 52 is provided around the adhesive needle 5 near the rounded end. The granulation tissue model 23 is placed at the bottom of the extraction socket 21 corresponding to the first molar, first premolar, and central incisor. The granulation tissue model 23 has a follicle-shaped structure that is thicker at the bottom and thinner at the top. The granulation tissue model 23 is made of a soft material. The granulation tissue model 23 is made of silicone material, which can be melted using a hot air gun. Melting material is prepared in advance when making the granulation tissue model 23. The silicone material is then used. The ball 51 is held and dipped into the molten silicone material through the groove 52 at the front end of the adhesive needle 5. The adhesive needle 5 is then held and the front end of the adhesive needle 5 is pressed against the bottom of the extraction socket 21. After the silicone material is successfully adhered to the inner wall of the extraction socket 21, it is pulled and stretched to form a granulation model 23 with a thicker bottom and thinner top. The production is convenient and quick. After the scraping operation of the granulation model 23 is completed, the spot-adhesion can be repeated. In addition, the granulation model 23 is set at the bottom of the extraction socket 21 corresponding to the first molar, first premolar, and central incisor, which can save costs.

[0035] In this invention, the maxillary sinus floor mucosa model 4 includes a splint 41. A groove 42 is provided on the upper front surface of the splint 41 to connect to the bottom of the extraction socket 21. A simulation sheet 43 that can simulate the maxillary sinus floor mucosa is detachably installed in the groove 42. The simulation sheet 43 is made of a tough material. A through hole 31 is provided on the dental model 3 corresponding to the position of each extraction socket 21. The dental model 3 is made of rubber. The simulation sheet 43 can be made of an ultra-thin silicone training skin structure, which has similar toughness and strength to the maxillary sinus mucosa. The simulation sheet 43 can be detachably installed through the groove 42 on the splint 41, making it easy to replace. The dental model 3 made of rubber is conducive to simulating various periodontal damage conditions according to the training content. The through hole 31 on the dental model 3 exposes the extraction socket 21, allowing a direct view of the internal condition of the extraction socket 21.

[0036] In this invention, the hinge base 1 includes a pair of symmetrically arranged bases 11, with one end of the two bases 11 hinged together. A connecting post 111 is provided on the front of each of the two bases 11, and a limiting block 112 is provided in the middle of the back of each of the two bases 11 to mutually restrict the rotation angle of the bases 11. Pressing blocks 113 are provided at the upper and lower ends of the back of the two bases 11 away from the hinge end. A connecting hole 20 is provided on the back of the model base 2, which can be detachably connected to the connecting post 111. Both the model base 2 and the hinge base 1 are made of resin material. The bases 11 and model base 2 are detachably mounted together via the connecting post 111 and the connecting hole 20, facilitating the combination of the bases 11 and model base 2. Alternatively, one model base 2 can be detached for training operations. The pressing block 113 facilitates pressing the two bases 11 with the hand to complete the opening and closing movement. The limiting block 112 restricts the opening angle of the two bases 11, mimicking the opening and closing degree of a real human mouth, which is beneficial for simulation operation training.

[0037] In practical use, the model base 2 can be detached from the base 11 individually, or two model bases 2 can be symmetrically mounted on the base 11 for simulation training. Before training, the simulation piece 43 is inserted into the clamping groove 42, and then the side of the clamping plate 41 with the simulation piece 43 exposed is inserted into the mounting groove 22. Then, the silicone material is heated and melted. Holding the end of the adhesive needle 5 with the gripping ball 51, the groove 52 at the front end of the adhesive needle 5 is dipped into the melted silicone material. Then, the end of the adhesive needle 5 with the groove 52 is inserted into the bottom of the extraction socket 21 corresponding to the first molar, first premolar, and central incisor, so that the adhesive material is adhered. After the silicone material at the tip of the pin 5 is attached to the inner wall of the bottom of the extraction socket 21, the silicone material is slowly stretched and cooled to form a granulation model 23. This is convenient to operate and facilitates quick and accurate completion of preparation work. During the scraping operation training of the extraction wound, the granulation model 23 at the bottom of the extraction socket 21 is scraped away. Finally, the splint 41 is removed, and the damage of the simulation piece 43 on the splint 41 can be observed to determine whether the scraping operation is correct. This helps trainees to identify problems and correct the scraping operation in time. The damaged simulation piece 43 can be quickly replaced and reinstalled in the splint 42 for retraining, which can improve the training effect of scraping the extraction wound.
