Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a visual mouth mirror. Background Art

[0002] A mouth mirror is a commonly used medical device used by dentists to assist in oral observation, illumination, traction, and protection. Its main uses include: (1) reflecting images of areas that cannot be directly seen, such as the distal and lingual surfaces of teeth and the occlusal surfaces of maxillary teeth; (2) it can be used to reverse or focus light on the examination area to increase local illumination; and (3) it can be used to traction or protect soft tissues such as the lips, cheeks, and tongue to facilitate oral examination or treatment.

[0003] Existing mouth mirrors are mainly composed of a lens and a handle. Since the lens and the handle are usually locked and cannot be adjusted, in actual use, medical staff can only change the overall angle of the mouth mirror to adjust the observation point, which makes the body stay in an abnormal forward-bending posture for a long time. This is an important reason why dentists are prone to neck and waist injuries. Secondly, the lens of the reflector of the existing mouth mirror is small, which often leads to poor field of vision clarity and unclear visual structure due to insufficient light in the mouth, obstruction of soft and hard tissues, treatment fog and other factors. Dentists need to concentrate, and their eyes are in a relatively high-intensity working state for a long time, which causes eye fatigue, thus affecting the diagnosis and treatment effect and quality. In addition, the mapping unit is small and the field of view is small. When encountering difficult dental diseases that require help or consultation from other doctors or senior doctors, they cannot share the dental disease tissue structure in the same field of view at the same time, and it is even more inconvenient for teachers and multiple interns or junior doctors to conduct real-time teaching activities in the same field of view.

DETAILED DESCRIPTION

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0026] The present invention provides a visual mouth mirror. Figure 1 and Figure 2 As shown, the device comprises an operating rod 1, a mapping unit 2 disposed at the front end of the operating rod 1, and a visual unit 3 disposed at the end of the operating rod 1. The mapping unit 2 includes a camera module 21 and a mouth lens 22. A capture gap is provided between the camera module 21 and the mouth lens 22 to enable the camera module 21 to capture the image mapped on the mouth lens 22. The visual unit 3 includes a freely rotatable display screen 31. The display screen 31 is electrically connected to the camera module 21 so that the camera module 21 transmits the captured image to the display screen 31 for display.

[0027] With the arrangement of this structure, during operation, it is only necessary to insert the oral lens 22 into the patient's oral cavity and adjust the position and angle of the oral lens 22. The camera module 21 can directly capture the image projected by the oral lens 22 at any position and angle. The display screen 31 is then used to display the image captured by the camera module 21 outside the patient's oral cavity, thereby obtaining the real-time situation inside the patient's oral cavity in all directions without blind spots, so that medical staff can directly observe the situation at any position inside the patient's oral cavity. Among them, the visual oral mirror of the embodiment of the present invention can directly observe the situation inside the patient's oral cavity through the oral lens 22, and can also observe the situation inside the patient's oral cavity through the display screen 31. There is no need for medical staff to be in an abnormal forward-bending posture for a long time, which effectively solves the problem of dentists being prone to neck and waist injuries. In particular, during oral education, the combination of the camera module 21 and the oral lens 22 allows teachers and students to simultaneously observe using a single visual oral mirror. Specifically, students can observe the interior of the patient's mouth through the image projected on the oral lens 22, while teachers can observe the interior of the patient's mouth through the image reflected on the display screen 31. This improves teaching efficiency and effectively addresses the issues of existing oral mirrors, such as small lenses, narrow fields of view, poor clarity, the inability of multiple people to simultaneously share dental structures, and the limited angle of movement. This enhances the various auxiliary diagnostic functions of existing oral mirrors and adds the ability to share the same field of view in real time. Preferably, the width or diameter of the operating rod 1 is less than 1 cm to facilitate observation by extending it out of the patient's mouth.

[0028] Furthermore, the camera module 21 is embedded in the front face of the operating rod, and a transparent isolation sleeve 4 is sleeved on the front end of the operating rod 1. A curved tongue depressor 41 is connected to the outer wall of the front end of the isolation sleeve 4. The mouthpiece 22 is located on the front side of the operating rod, facing the collection area of ​​the camera module 21, and the mouthpiece 22 is connected to the isolation sleeve 4 via the tongue depressor 41.

[0029] Through the setting of this structure, since the mouth mirror is usually inserted into the patient's oral cavity for use, in order to avoid cross infection, traditional mouth mirrors are all disposable products. The embodiment of the utility model is to connect the isolation tube sleeve 4 to the front end of the operating rod 1, thereby isolating the part of the rod body of the operating rod 1 that extends into the patient's oral cavity from the patient's oral environment to avoid contamination of the operating rod. The camera module 21 is embedded on the operating rod, and the mouth lens 22 is located on the isolation tube sleeve 4. Since the isolation tube sleeve 4 generally adopts a sterile medical plastic tube sleeve, the cost of it and the mouth lens 22 is extremely low. Therefore, when the visual mouth mirror of the embodiment of the utility model is used again, it is only necessary to process the used isolation tube sleeve 4 and mouth lens 22, and put a new sterile isolation tube sleeve 4 and sterile mouth lens 22 on the operating rod 1 for repeated use. This not only effectively avoids cross infection during repeated use, ensures medical safety, but also reduces costs, ensures that it can be mass-produced and applied, and has a large market prospect. In addition, the curved tongue depressor 41 can be used to pull or press soft tissues such as the lips, cheeks, and tongue, so as to facilitate the oral lens 22 to observe the patient's oral cavity, and can closely fit the contours inside the patient's oral cavity to reduce discomfort, improve the accuracy of observation, and make it easier to operate, so as to accurately control the observation direction of the oral lens 22, so that it can better focus on the specific area that needs to be examined or treated, thereby allowing the doctor to conduct examinations more flexibly.

[0030] Furthermore, the operating lever 1 includes a camera integration lever 11 and a display integration lever 12, which are separately arranged. The end of the camera integration lever 11 and the front end of the display integration lever 12 are detachably connected. An electrical connector 111 is provided on the end surface of the camera integration lever 11. The camera module 21 is embedded in the front surface of the camera integration lever 11, and the camera module 21 and the electrical connector 111 are electrically connected.

[0031] An electrical connection socket 121 corresponding to the electrical connection plug 111 is provided on the front end surface of the display integration rod 12 . The display screen 31 is provided at the end of the display integration rod 12 , and the display screen 31 is electrically connected to the electrical connection socket 121 .

[0032] By setting up this structure, the camera module 21 and the display screen 31 are divided into two independent modules by utilizing the split camera integration rod 11 and the display integration rod 12. On the one hand, when one of the modules in the camera module 21 and the display screen 31 fails, only the failed module can be replaced without replacing the entire visual port mirror, thereby reducing replacement costs and increasing the service life and usage rate of the product. On the other hand, when the visual port mirror is not in use, the camera module 21 and the display screen 31 can be quickly disassembled without occupying a large space, thereby saving space when storing. During installation, it is only necessary to connect the electrical connector 111 on the end surface of the camera integration rod 11 with the electrical connector jack 121 on the front surface of the display integration rod 12 to quickly install and electrically connect the camera module 21 and the display screen 31, thereby facilitating subsequent data transmission and hardware control.

[0033] Furthermore, the front end of the display integration rod 12 is provided with a socket 13, and an electrical connector jack 121 is located at the bottom of the socket 13. The rear end of the camera integration rod 11 is provided with a corresponding plug-in protrusion, and an electrical connector 111 is located on the end face of the plug-in protrusion. This arrangement facilitates the quick removal and installation of the display integration rod 12 and the camera integration rod 11 by means of plug-in connection.

[0034] Furthermore, the visual port mirror also includes a main control chip and a power module arranged at the end of the operating rod. The display screen 31 is electrically connected to the camera module 21 through the main control chip, and the power module is electrically connected to the main control chip so that the power module supplies power to the main control chip. Through the arrangement of this structure, the main control chip is preferably an STM32 microcontroller, which has multiple GPIO (general purpose input and output) pins that can be used to control switches and receive signals. It generally includes a microcontroller or a logic circuit for processing signals from each switch and controlling the corresponding unit. The signal output port of the main control chip can be connected to the display screen 31 and the camera module 21 through switching elements such as relays, transistors or MOSFETs for easy integrated control. At the same time, the power module is utilized to power the entire control system to ensure the normal use of the visual port mirror. The power module is preferably a lithium battery or a button battery.

[0035] Further, combined with Figure 3 and Figure 4As shown, an annular groove 14 is provided on the front end surface of the operating rod 1 along the circumference of the outer side of the camera module 21, and a heating wire 5 is provided in the annular groove 14. The heating wire 5 is electrically connected to the main control chip, and the display screen 31 is provided with an electric heating switch 51 electrically connected to the main control chip, so that the heating wire 5 heats and demists the camera module 21. Through the setting of this structure, due to the temperature difference or moisture that usually exists in the patient's mouth, the lens of the camera module 21 will be fogged, affecting the shooting quality. Therefore, in the process of using the visual mouth mirror of the embodiment of the utility model to observe the patient's mouth, the heating wire 5 can be used to perform low-temperature heating on the camera environment of the camera module 21. While ensuring that the temperature is appropriate, the fog on the lens of the camera module 21 can be effectively eliminated to keep the picture clear.

[0036] Furthermore, an illumination unit 6 is provided on the front end of the operating lever, circumferentially outside the camera module 21. The illumination unit 6 is electrically connected to the main control chip, and an illumination switch 61 is provided on the display screen 31, electrically connected to the main control chip, so that the illumination unit 6 can provide auxiliary illumination for the image acquisition area of ​​the camera module 21. This structural arrangement allows the illumination unit 6 to provide necessary light in dark or low-light environments, thereby improving the image acquisition environment of the camera module 21 and enabling the operator to more clearly see the operating area, thereby reducing erroneous operations caused by unclear vision.

[0037] Furthermore, the visual unit 3 includes a rotational assembly 7, which comprises a handle 71, a hinged seat 72, and a ball head 73. The bottom of the handle 71 is connected to the end of the operating rod, and a receiving slot is defined at the top of the handle 71. The hinged seat 72 is located within the receiving slot and is pivotally connected to the inner wall of the slot, allowing the hinged seat 72 to rotate in the forward and backward direction of the operating rod. The ball head 73 is hingedly connected to the hinged seat 72, and the display screen 31 is connected to the ball head 73, allowing the display screen 31 to rotate freely in the horizontal direction. Through the setting of this structure, the hinge seat 72 and the inner wall of the accommodating groove are rotated to enable the hinge seat 72 to be flipped along the front and back directions of the operating rod, and the ball hinge structure is used to enable the display screen 31 to rotate 360° freely in the horizontal direction. Therefore, the display screen 31 can be adjusted to any angle for observation according to the operator's needs, so that one operator can observe the internal conditions of the patient's mouth through the image projected on the oral lens 22, while the other operator can observe the internal conditions of the patient's mouth through the image fed back on the display screen 31 at the same time.

[0038] Further, look back Figure 2The handle 71 has an integrated chamber inside, with the main control chip located within. A battery slot 711, isolated from the integrated chamber, is provided on the outer wall of the handle 71. The power module is located within the battery slot 711, which is fitted with a battery cover 712 that snaps onto the slot. This structural arrangement, utilizing the isolation between the integrated chamber and the battery slot 711, allows the main control chip and the power module to be installed separately, preventing interference between the circuits and facilitating replacement of the power module.

[0039] Furthermore, the display screen 31 includes a housing 311 and a display module 312 mounted on the housing 311. The housing 311 is also provided with a display switch 313 and a camera switch 314. With this configuration, the input ports of switches such as the display switch 313 and the camera switch 314 can be connected to the signal input ports of the main control chip via components such as resistors and capacitors for signal matching and protection.

[0040] The visual mouth mirror of the embodiment of the present invention utilizes the acquisition gap between the camera module 21 and the mouth lens 22. During operation, it is only necessary to insert the mouth lens 22 into the patient's oral cavity and adjust the position and angle of the mouth lens 22 so that the camera module 21 can directly acquire the image projected by the mouth lens 22 at any position and angle, and use the display screen 31 to display the image acquired by the camera module 21 outside the patient's oral cavity, thereby obtaining the real-time situation inside the patient's oral cavity in all directions without blind spots, so that medical staff can directly observe the situation at any position inside the patient's oral cavity, which facilitates the dentist's diagnosis and treatment of the patient. At the same time, the lighting unit 6 is used for lighting and fill-in light to ensure the normal operation of the camera module 21, and the heating wire 5 is used to slightly increase the temperature around the camera module 21 to avoid the situation where the camera module 21 is not clearly illuminated due to aerosol, effectively solving the problem of difficult observation with the existing mouth mirror.
