Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a mouth mirror, one of the most common and essential medical devices in oral clinical applications. Background Technology

[0002] A mouth mirror is a medical device used for oral examination and treatment, typically consisting of a base with a lens and a handle. The main function of a mouth mirror is to allow doctors to clearly observe the inside of the oral cavity, including the teeth, gums, tongue, cheeks, and throat.

[0003] In the field of microsurgical treatment of endodontics, the anti-fogging technology of oral mirrors has always been a pressing technical challenge. With the development of minimally invasive microsurgical techniques, medical staff need to use oral mirrors for precise observation and manipulation of dental tissues during microsurgical treatments of endodontics. However, in actual clinical practice, due to the small treatment area and limited operating space, liquids easily splash onto the oral mirror surface during microsurgical procedures such as removing decay under a microscope using a high-speed turbine handpiece, irrigating and disinfecting the pulp chamber during microsurgical root canal treatment, and microsurgical periapical surgery, forming a water mist layer. This water mist phenomenon significantly reduces the mirror's light transmittance, causing blurred vision and severely affecting the doctor's observation accuracy of the treatment area, thus impacting treatment effectiveness and efficiency.

[0004] In delicate procedures such as microscopic endodontic treatment, dentists often need to maintain a continuous two-handed operation: one hand holding the treatment instrument, and the other holding the mouth mirror. When the mirror fogs up, the current solution is to use an air gun to blow away the fog. This method requires the dentist to interrupt their current right-hand operation to operate the air gun, necessitating multiple uses throughout the treatment. This frequent hand-switching not only prolongs the patient's mouth-opening time, reducing patient compliance and disrupting the continuity of treatment, but also increases the dentist's workload and the patient's psychological burden, significantly reducing treatment effectiveness and efficiency.

[0051] While existing technologies offer some anti-fogging solutions for dental lenses, such as chemical anti-fogging coatings and heated defogging, these methods have significant limitations in the dental treatment environment. Firstly, chemical coatings may affect the optical performance of the lens, and they are easily corroded by rinsing agents, leading to wear and tear with long-term use. Secondly, physical anti-fogging methods like heated lenses are difficult to implement in the confined space of the oral cavity and can easily cause patient discomfort. Therefore, current defogging methods primarily rely on air gun blowing. However, the current handheld air gun defogging method requires frequent hand switching, which not only prolongs treatment time and interrupts treatment continuity but also increases the workload of the dentist and the psychological burden on the patient, exacerbating dental phobia and significantly reducing overall treatment effectiveness and efficiency, which does not align with the clinical concept of "comfortable treatment."

[0052] like Figures 1 to 6 As shown, this embodiment provides a mouth mirror that can be used in conjunction with a microscope to achieve microscopic treatment of dental pulp. The mouth mirror includes a base 11, a handle 12, a rotating ring 13, a lens 14, a nozzle 15, a first driver 16, a gear 17, and an air pump 18.

[0053] The mirror base 11 has a mounting groove 111. The mounting groove 111 is a circular groove, and the mirror base 11 is disc-shaped with rounded corners to reduce discomfort and injury caused by right angles contacting the human body. The mounting groove 111 is located on the upper surface of the mirror base 11. A handle 12 is connected to the side of the mirror base 11 and is used for dentists and other medical personnel to hold.

[0054] The rotating ring 13 has a plurality of protruding teeth 131 evenly spaced along its circumference. The protruding teeth 131 can be disposed on the outer circumferential surface of the rotating ring 13 or on the inner circumferential side surface of the rotating ring 13. The rotating ring 13 is rotatably mounted in the mounting groove 111 of the mirror base 11. In this embodiment, the protruding teeth 131 are disposed on the inner circumferential side surface of the rotating ring 13, so that the gear 17 can be disposed within the rotating ring 13, reducing the space occupied by the rotating ring 13 and the gear 17 in the mounting groove 111, and reducing the volume of the mirror base 11.

[0055] The lens 14 is disposed on the lens base 11 and located within the area enclosed by the rotating ring 13. The lens 14 is disposed in the mounting groove 111 of the lens base 11 via the support base 19. A sealing ring can be provided on the edge of the lens 14, and the sealing ring abuts against the inner circumferential side of the rotating ring 13.

[0056] The nozzle 15 has an air outlet and is mounted on the rotating ring 13. The lens 14 is located below the nozzle 15, and the air outlet sprays gas horizontally onto the mirror surface of the lens 14.

[0057] The first driver 16 is installed in the mounting slot 111 of the mirror base 11. The first driver 16 is disposed on the bottom wall of the mounting slot 111. The first driver 16 is a driving component such as a motor. For example, in this embodiment, the first driver 16 is a micro motor. The micro motor is an existing component. Using a micro motor as a driving component will not increase the volume of the mirror base 11 in the prior art, making it convenient for the mirror base 11 to be placed in the oral cavity.

[0058] Gear 17 is installed at the output end of the first driver 16. Gear 17 meshes with the protruding teeth 131 of the rotating ring 13. After the lens 14 is installed, it forms a sealed cavity with the lens mount 11 and the rotating ring 13. The first driver 16 and gear 17 are located inside the sealed cavity, and the lens 14 covers the first driver 16 and gear 17.

[0059] The air pump 18 is connected to the nozzle 15. The air pump 18 can be mounted on the handle 12 or installed separately, with the air pump 18 and nozzle 15 connected by a pipe when using the mouthpiece. In this embodiment, the air pump 18 is a miniature electric air pump 18, which is located at the end of the handle 12. The air pump 18 and the mouthpiece base 11 are located at opposite ends of the handle 12, which can balance the weight of the handle 12.

[0060] Multiple nozzles 15 are arranged at intervals along the circumference of the lens 14, and the air outlet of each nozzle 15 faces the mirror surface of the lens 14. The height of both the nozzles 15 and the lens 14 is lower than the upper surface of the lens base 11 to prevent the nozzles 15 and the lens 14 from protruding from the lens base 11 and to improve patient comfort.

[0061] In this embodiment, when using the oral mirror, the medical staff holds the handle 12 and places the mirror base 11 in the patient's mouth. They observe the teeth, gums, and other areas through the lens 14, and perform dental treatment using instruments such as root canal probes, vertical pressure devices, and pulp extraction needles. During dental treatment, the teeth need to be cleaned multiple times with rinsing solution. When the rinsing solution causes fogging on the mirror surface 14, the air pump 18 and the first actuator 16 are activated, allowing the nozzle 15 to blow air onto the mirror surface to remove the fog. The first actuator 16 drives the rotating ring 13, causing the nozzle 15 to rotate around the lens 14, thus defogging the entire mirror surface. This avoids affecting the doctor's observation accuracy of the treatment area due to decreased mirror transmittance and visual clarity. The multiple defogging processes do not require the medical staff to put down the medical instruments and switch to an air gun, improving the effectiveness and efficiency of endodontic treatment.

[0062] Furthermore, the mirror mount 11 includes an upper housing and a lower housing. The upper and lower housings are detachably connected, facilitating the installation of components such as the first driver 16 and the gear 17. A sealing ring is provided between the upper and lower housings for waterproofing.

[0063] Optionally, in some embodiments, the lens 14 is circular, and the air outlet of the nozzle 15 blows gas horizontally along the horizontal plane of the lens surface, with each air outlet of the nozzle 15 facing horizontally toward the center of the lens surface of the lens 14.

[0064] In other embodiments, the air outlet of nozzle 15 is slightly higher than the mirror surface of lens 14. The mouthpiece also includes a second actuator 20. Multiple spaced bases 21 are provided on the inner circumferential side of rotating ring 13, each base 21 corresponding to a single nozzle 15. The nozzle 15 is rotatably mounted on the base 21. The second actuator 20 is driven by the nozzle 15 to adjust the angle between the nozzle 15 and lens 14. The rotation axis of nozzle 15 is parallel to the mirror surface, allowing nozzle 15 to swing up and down, thus positioning the air outlet of nozzle 15 towards different positions on the mirror surface of lens 14. During defogging, the second actuator 20 can drive nozzle 15 to rotate, aligning the air outlet with the fogged area for more precise and efficient defogging.

[0065] Key reference Figure 5 and Figure 6In one embodiment, the rotating ring 13 is provided with a receiving groove 132 for accommodating the second driver 20. The second driver 20 includes a first mounting member 201, a second mounting member 202, a connector 203, a magnetic member 204 disposed on the connector 203, a first electromagnet 205 disposed on the first mounting member 201, a second electromagnet 206 disposed on the second mounting member 202, and a first elastic member 207 and a second elastic member 208. The first electromagnet 205 and the second electromagnet 206 can be powered by an external power source or by a battery 24 built into the mouthpiece. When the first electromagnet 205 and the second electromagnet 206 are energized, they generate opposite magnetic poles. The first electromagnet 205 and the second electromagnet 206 are not energized at the same time. The two magnetic poles of the magnetic member 204 correspond to the first electromagnet 205 and the second electromagnet 206 respectively. When the first electromagnet 205 or the second electromagnet 206 is energized, both the first electromagnet 205 and the second electromagnet 206 can be attracted to the magnetic member 204. The base 21 has an adjustment groove 211, and a rotating shaft 22 is rotatably installed in the adjustment groove 211. The rotating shaft 22 is horizontally set. One end of the nozzle 15 is located in the adjustment groove 211 and connected to the rotating shaft 22, and the other end of the nozzle 15 has an air blowing port located outside the adjustment groove 211.

[0066] The first mounting component 201 and the second mounting component 202 are spaced apart from top to bottom on the base 21. A first limiting component and a second limiting component are integrally formed on the base 21, also spaced apart from top to bottom. The first elastic component 207 and the second elastic component 208 can be elastic components such as columnar springs. Both the first elastic component 207 and the second elastic component 208 are located between the first mounting component 201 and the second mounting component 202. The connecting component 203 is connected to the rotating shaft 22 and located between the first elastic component 207 and the second elastic component 208. One end of the first elastic component 207 and one end of the second elastic component 208 are connected to the connecting component 203, and the other ends of the first elastic component 207 and the second elastic component 208 are connected to the base 21, such that the first elastic component 207 is clamped between the first mounting component 201 and the first limiting component, and the second elastic component 208 is clamped between the second mounting component 202 and the second limiting component. The first electromagnet 205, the second electromagnet 206, and the magnetic element 204 are arranged radially along the rotating shaft 22, with the magnetic element 204 located between the first electromagnet 205 and the second electromagnet 206. The nozzle 15 can be horizontally positioned using the elastic force of the first elastic element 207 and the second elastic element 208. When it is necessary to change the angle of the nozzle 15 so that the air outlet is precisely aligned with the fogging area of ​​the lens 14, energizing the first electromagnet 205 or the second electromagnet 206 allows the magnetic force between the first electromagnet 205 and the magnetic element 204, or the magnetic force between the second electromagnet 206 and the magnetic element 204, to overcome the elastic force of the first elastic element 207 and the second elastic element 208, thereby causing the nozzle 15 to swing up and down, thus adjusting the orientation of the air outlet.

[0067] Furthermore, an elastic waterproof cloth 23 is provided at the opening of the adjustment groove 211 of the base 21. The elastic waterproof cloth 23 connects the nozzle 15 and the base 21 to cover the gap between the nozzle 15 and the base 21. The elastic waterproof cloth 23 does not interfere with the rotation of the nozzle 15 and also plays a sealing role to prevent the rinsing fluid from entering the adjustment groove 211 of the base 21.

[0068] In one embodiment, the mouth mirror further includes a battery 24, a control module 25 electrically connected to the battery 24, and a button assembly 26. The battery 24 and control module 25 are both housed in the mounting slot 111 of the mirror holder 11, and the button assembly 26 is located on the outer side of the handle 12. For ease of operation by medical personnel, the button assembly 26 is electrically connected to the first actuator 16, the second actuator 20, and the air pump 18 via the control module 25. The button assembly 26 can control the opening and closing of components such as the first actuator 16, the second actuator 20, and the air pump 18, and can also adjust the air volume of the air pump 18, the rotation direction of the rotating ring 13 driven by the first actuator 16, and the rotation direction of the nozzle 15 driven by the second actuator 20.

[0069] Furthermore, the mouth mirror can also be powered directly by connecting an external power outlet via a cable. After each use, the mouth mirror can be disinfected using methods such as ultraviolet light, high temperature, or spraying with alcohol disinfectant.

[0070] Optionally, the button assembly 26 includes a first switch button, a second switch button, a third switch button, a first rotary button, a second rotary button, a first air volume adjustment button, a second air volume adjustment button, a first angle adjustment button, and a second angle adjustment button. The first switch button, the first rotary button, and the second rotary button are all electrically connected to the first driver 16 via the control module 25. The first switch button controls the opening and closing of the first driver 16, and the first and second rotary buttons control the forward and reverse rotation of the first driver 16, respectively. The second switch button, the first angle adjustment button, and the second angle adjustment button are all electrically connected to the second driver 20 via the control module 25. The second switch button controls the opening and closing of the second driver 20, and the first and second angle adjustment buttons control the energization of the first electromagnet 205 and the second electromagnet 206, respectively. The third switch button, the first air volume adjustment button, and the second air volume adjustment button are all electrically connected to the air pump 18 through the control module 25. The third switch button is used to control the air pump 18 to turn on and off, and the first air volume adjustment button and the second air volume adjustment button are used to control the increase and decrease of the output air volume of the air pump 18, respectively.

[0071] Furthermore, the mirror base 11 is equipped with a charging interface, which is electrically connected to the battery 24 to charge the battery 24. A waterproof plug is installed on the charging interface to ensure waterproofing.

[0072] In one embodiment, the mouth mirror further includes an air supply tube 27. The handle 12 is provided with a tube channel communicating with the mounting groove 111. One end of the handle 12 is connected to the mirror base 11, and the air pump 18 is located at the other end of the handle 12. One end of the air supply tube 27 is connected to the air pump 18, and the other end of the air supply tube 27 passes through the tube channel and the mounting groove 111 in sequence and is connected to the nozzle 15, thereby realizing the connection between the air pump 18 and the nozzle 15.

[0073] Furthermore, the mouthpiece also includes a multi-port connector 28 and multiple branch pipes 29. Each branch pipe 29 corresponds to one nozzle 15, allowing gas to be distributed to different nozzles 15 via the multi-port connector 28. The air pump 18 is connected to the multi-port connector 28 via an air supply pipe 27, and the multi-port connector 28 is connected to the nozzles 15 via the branch pipes 29. The branch pipes 29 pass through the base 21 and connect to the nozzles 15; the branch pipes 29 are flexible and do not affect the rotation of the nozzles 15.

[0074] Optionally, the outer surface of the handle 12 is provided with anti-slip texture 121. The anti-slip texture 121 can be a protrusion and / or a groove provided on the outer surface of the handle 12 to achieve anti-slip.
