Description

Technical Field

[0001] This utility model relates to the field of oral treatment auxiliary tools, and in particular to an oral retractor. Background Technology

[0002] During oral diagnosis and treatment, maintaining the patient's mouth in a moderately open state and effectively retracting the soft tissues such as the lips, cheeks, and tongue is crucial for doctors to obtain a clear and stable field of vision and to perform surgery or procedures safely and accurately.

[0003] In current technology, most oral retractors are of a fixed size, which cannot perfectly fit the oral conditions of all patients. Retractors that are too small cannot provide sufficient operating space; while retractors that are too large may overstretch oral soft tissues, such as the cheeks, lips, and corners of the mouth, causing discomfort and pain to the patient. During treatment, it is sometimes necessary to fine-tune the width of the oral cavity opening, but fixed-size retractors cannot achieve this dynamic adjustment. Doctors need to frequently change instruments or use other auxiliary means, which disrupts the smoothness of the treatment process. Utility Model Content

[0004] The purpose of this invention is to provide an oral retractor that can adaptively adjust the width of the patient's oral cavity opening, improve the patient's comfort, and ensure the smoothness of the treatment process.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An oral retractor is provided, comprising:

[0007] The retractor body includes a gripping part and a supporting part. The supporting part is connected to the end of the gripping part. The supporting part is arc-shaped and symmetrical along the central axis of the gripping part. The inner contour of the supporting part is modeled after the contour of human periodontal teeth.

[0008] An adjusting member is provided with an adjusting groove at the end of the gripping part near the supporting part. A threaded hole is provided on the first side wall of the adjusting groove, and a through hole is provided on the second side wall of the adjusting groove. The threaded hole and the through hole are opposite to each other and coaxially arranged. The adjusting member passes through the through hole and is screwed into the threaded hole.

[0009] Twisting the adjusting member can adjust the opening width of the support.

[0010] As an alternative to an oral retractor, the support is inclined in a direction away from the tongue, relative to the horizontal plane.

[0011] As an alternative to the oral retractor, when the oral retractor is used on the mandible, the support part is provided with a lip baffle, and the lip baffle has a gap that allows the frenulum of the lip to pass through.

[0012] As an alternative to the oral retractor, the oral retractor also includes a tongue baffle, the two ends of which are connected to the two ends of the support part in a corresponding manner. The tongue baffle is arc-shaped, and the arc-shaped opening faces the side away from the gripping part.

[0013] As an alternative to an oral retractor, the width of the tongue baffle gradually increases along the direction close to the gripping part.

[0014] As an optional solution for oral retractors, the tongue baffle is made of silicone.

[0015] As an alternative to the oral retractor, the connection between the tongue baffle and the support is achieved by secondary injection molding, assembly snap-fit, or adhesive bonding.

[0016] As an optional solution for oral retractors, the gripping part is provided with an anti-slip structure.

[0017] The beneficial effects of this utility model are:

[0018] This invention provides an oral retractor. An adjustment groove is formed at the end of the gripping part near the support part. A threaded hole is formed on the first side wall of the adjustment groove, and a through hole is formed on the second side wall. The threaded hole and the through hole are opposite to each other and coaxially arranged. An adjustment component passes through the through hole and is screwed into the threaded hole. Twisting the adjustment component adjusts the opening width of the support part, allowing for flexible adjustment according to the patient's oral condition and ensuring patient comfort. Simultaneously, during treatment, the doctor can also dynamically adjust the opening width as needed, ensuring a smooth treatment process. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown, this embodiment provides an oral retractor, including a retractor body 1 and an adjusting component 2. The retractor body 1 includes a gripping part 11 and a supporting part 12. The supporting part 12 is connected to the end of the gripping part 11. The supporting part 12 is arc-shaped and symmetrical along the central axis of the gripping part 11. The inner contour of the supporting part 12 is designed to conform to the contour of the human periodontal tissue, so as to naturally fit the periodontal morphology, reduce the patient's swelling and pain and foreign body irritation, and avoid local pressure damage. An adjusting groove 111 is provided at the end of the gripping part 11 near the supporting part 12. The first side wall of the adjusting groove 111 has a threaded hole and the second side wall has a through hole. The threaded hole and the through hole are opposite to each other and coaxially arranged. The adjusting component 2 passes through the through hole and is screwed into the threaded hole. By screwing the adjusting component 2, the opening width of the supporting part 12 can be adjusted flexibly according to the patient's oral condition to ensure the patient's comfort. At the same time, during the treatment process, the doctor can also dynamically adjust the opening width as needed to ensure the smoothness of the treatment process.

[0035] Understandably, the aforementioned oral retractor can be used to retract the soft tissues on the buccal side of the maxillary periodontium as well as the soft tissues on the buccal side of the mandibular periodontium. Specifically, during edentulous jaw scanning, it can expose the palatal vault, alveolar ridge crest, labial and buccal clefts of the alveolar ridge, both sides of the palatal vault, and the attachment site of the labial and buccal frenulum, providing sufficient operating space for the scanning head and facilitating scanning or impression taking. For edentulous scanning and diagnosis, it can also effectively increase the doctor's field of vision, facilitating diagnostic operations, shortening treatment time, and improving the patient's experience.

[0036] Specifically, the gripping part 11 and the supporting part 12 of the retractor body 1 are integrally formed, and the retractor body 1 is made of a relatively hard medical plastic material, which has good structural strength and rigidity, and at the same time, can effectively improve durability and reliability. The aforementioned medical plastic material is a conventional material that is currently available, and will not be described in detail here.

[0037] Optionally, the support portion 12 is inclined in a direction away from the tongue relative to the horizontal plane. That is, the support portion 12 of the oral retractor for the mandible is inclined downward, and the support portion 12 of the oral retractor for the maxilla is inclined upward. Figure 2 The oral retractor shown is for the maxilla. The upwardly tilted support 12 more effectively pushes the upper lip upward, fully exposing the maxillary anterior teeth, alveolar ridge crest, and vestibule. It also helps direct pressure towards the alveolar bone lateral walls and the deeper vestibule crest, areas that are generally more resilient to pressure, thus reducing direct pressure on the more vulnerable marginal soft tissues. Similarly, for the mandible, the downwardly tilted support 12 fully exposes the lower periodontal tissues.

[0038] Furthermore, the upper surface of the support part 12 is provided with a mark to facilitate the correct use of the oral retractor and prevent it from being held upside down. Specifically, in this embodiment, the mark is the word "TOP"; in other embodiments, the mark may be other words or patterns, or the mark may be placed in other positions, as long as it can serve the purpose of identification, and no specific limitation is made here.

[0039] Optionally, the grip portion 11 is provided with an anti-slip structure. Specifically, the anti-slip structure is an anti-slip pad, such as a rubber pad; or, the anti-slip structure is an anti-slip protrusion, which can be dot-shaped protrusions or textured protrusions of any shape; or, the anti-slip structure is an anti-slip groove, which can be of any shape, as long as it can improve the stability of the doctor's grip. The specific form is similar to existing technology, and this embodiment does not impose specific limitations, as long as it can enhance stability.

[0040] For example, in this embodiment, the grip portion 11 is provided with anti-slip grooves to avoid slippage caused by the doctor wearing gloves or getting saliva on the gloves.

[0041] Optionally, the adjusting component 2 is provided with a screw-on part. Specifically, the screw-on part can be a protruding structure, such as a knob or a wing. When the adjusting component 2 needs to be screwed on, the doctor can simply hold the screw-on part with his hand to operate it. The operation is simple and convenient, and no auxiliary tools are needed. The operation can be completed by hand. Alternatively, the screw-on part can also be a grooved structure, such as an internal hexagonal, Phillips head, or flathead screw, and can be screwed on using a screwdriver that is compatible with it.

[0042] In this specific embodiment, the screwing part is an internal hexagonal groove located at the end of the adjusting member 2. When the adjusting member 2 needs to be screwed, a suitable screwdriver is required. Compared with the protruding structure, the internal hexagonal groove allows the end of the adjusting member 2 to be concealed within the through hole, avoiding interference with the soft tissue in the patient's oral cavity.

[0043] Example 2

[0044] like Figures 3 to 5 As shown, this embodiment provides an oral retractor, which is a further improvement on the oral retractor for the mandible in Embodiment 1. The difference between it and Embodiment 1 is as follows:

[0045] A lip baffle 13 is provided on the support part 12 to stop the lower lip. The lip baffle 13 has a gap to allow the frenulum to pass through, so as to prevent the lip baffle 13 from interfering with the frenulum and improving the patient's comfort. Specifically, in this embodiment, the lip baffle 13 includes two spaced-apart segmented baffles 131, and the two segmented baffles 131 surround the aforementioned gap.

[0046] Optionally, such as Figure 3 and Figure 4As shown, the oral retractor also includes a tongue baffle 3, with its two ends connected to the two ends of the support 12. The tongue baffle 3 is arc-shaped, and its arc-shaped opening faces away from the gripping part 11 to conform to the natural curvature of the tongue and reduce patient discomfort.

[0047] Furthermore, combined Figure 5 Along the direction close to the gripping part 11, the width of the tongue baffle 3 gradually increases. That is, the two ends of the tongue baffle 3 are narrow and the middle is wide. The wider middle part can better cover the middle of the tongue, ensuring the guiding and restraining effect on the tongue, while the narrower ends can reduce the stimulation of the proximal surfaces of the teeth and the gum line, reduce mucosal damage and foreign body sensation, and reduce the amount of material used, taking into account both structural stability and lightweight.

[0048] Optionally, the tongue guard 3 is made of silicone. As a chemically stable inert material, silicone is almost non-irritating to sensitive tissues such as oral mucosa and tongue, and is not likely to cause allergic reactions or inflammation. It is suitable for contact with the oral environment, especially for children, the elderly or people with fragile oral mucosa. In addition, silicone is soft and elastic, and can deform slightly according to the physiological structure inside the mouth, fits closely but will not cause pressure, thereby reducing the patient's foreign body sensation and discomfort.

[0049] Optionally, the connection between the tongue baffle 3 and the support part 12 is achieved through secondary injection molding. Secondary injection molding enables a seamless fit between the tongue baffle 3 and the support part 12, eliminating potential gaps during assembly and improving the overall aesthetics. Furthermore, the thermal expansion coefficients of the tongue baffle 3 and the support part 12 can be designed to be complementary, resulting in high connection stability.

[0050] Alternatively, the connection between the tongue baffle 3 and the support part 12 can be achieved by assembly snap-fit. The tongue baffle 3 and the support part 12 are respectively provided with corresponding slots and snap-fit ​​parts. No auxiliary tools are required. The fixed connection can be completed by simply aligning and pressing manually, which is beneficial to improving assembly and production efficiency.

[0051] Alternatively, the connection between the tongue baffle 3 and the support part 12 can be made by adhesive bonding. The adhesive bonding forms a continuous bonding layer on the contact surface through adhesive, which can evenly distribute the external force to the entire connection area, reducing the risk of cracking and deformation. At the same time, no complicated equipment is required, and the glue can be applied manually. In addition, the price of adhesive is relatively low, which can significantly reduce production costs.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
