Description

An examination device for throat examination in otolaryngology Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to an examination device for throat examination in otolaryngology. Background Technology

[0002] During otolaryngological examinations, doctors typically use a laryngoscope or fiberoptic laryngoscope to examine the patient's throat to determine if there are any conditions such as inflammation, masses, or vocal cord abnormalities. Currently, the most common technologies are the "traditional direct laryngoscope" or the "light-guided fiberoptic laryngoscope." These devices usually consist of the following components: a mirror or fiber optic cable with an arc-shaped blade that can be inserted into the mouth or pharynx; a light source or camera for illuminating or imaging the throat; and a handle or grip for easy operation by the doctor.

[0003] When necessary, it will also be equipped with wires or data transmission components that connect to the display terminal, making it convenient for doctors to observe on an external display screen. Technical issues

[0004] Based on the above analysis, the problems and shortcomings of the existing technology are as follows:

[0005] (1) The insertion process is prone to discomfort and misoperation: When inserting a traditional laryngoscope or a visual fiber laryngoscope, the operator needs to have a high level of hand-eye coordination. Otherwise, it is easy to cause nausea, vomiting or local trauma to the patient. At the same time, when the doctor operates in the narrow oral cavity and pharyngeal cavity, the field of vision is limited and the angle is difficult to control. If the operation is improper, it may damage the patient's pharyngeal mucosa.

[0006] (2) Limited field of view and difficulty in obtaining multi-angle images: Traditional laryngoscopes can only provide a single angle of view and cannot flexibly adjust the position of the camera or optical mirror during the examination, resulting in the inability to accurately and clearly observe some lesions located on the side or difficult to see directly.

[0007] (3) Limited lighting and imaging quality: Due to the dim lighting inside the patient's mouth and the complex structure of the larynx, the brightness and light distribution of traditional light sources are often not uniform enough, resulting in a decrease in imaging quality. Doctors need to frequently adjust the angle or the brightness of the light source to obtain a clearer image, which increases the difficulty of operation and examination time.

[0008] (4) Lack of auxiliary functions: Although some existing devices can transmit images to the display screen, they lack auxiliary functions for the special needs of the throat, such as surface spraying of anesthetic, local irrigation or suction, etc. This means that doctors need to use additional instruments to complete a series of examinations and auxiliary operations, which increases the burden on the equipment and reduces work efficiency.

[0009] In summary, there is an urgent need for a throat examination device that is compact, easy to operate, capable of multi-angle observation, and has certain auxiliary functions, in order to improve the safety and efficiency of clinical examinations in otolaryngology. Technical solutions

[0010] In view of the problems existing in the prior art, the present invention provides an examination device for throat examination in otolaryngology.

[0011] The present invention is implemented as follows: an examination device for otolaryngological throat examination includes:

[0012] Mainframe module, front-end inspection header module, external display and control module;

[0013] The main frame module, connected to the front inspection head module, external display and control module, is used to provide a handle, control panel and drive shaft assembly;

[0014] The front-end inspection header module is connected to the main rack module, external display and control module, and is used to inspect the header;

[0015] An external display and control module, connected to the main frame module and the front-end inspection head module, is used for data display and device control.

[0016] Furthermore, the mainframe module:

[0017] Handle module: Ergonomically designed with a non-slip textured surface, and internally accommodates a power supply battery or wired power interface;

[0018] Control panel: Located on the top or side of the grip, containing buttons or knobs for controlling camera rotation, light source brightness adjustment, and auxiliary component activation / deactivation;

[0019] Drive shaft assembly: Extending from inside the handle to the examination head, it transmits rotational signals, whether manually operated or electrically driven by the doctor, to the front-end camera module.

[0020] Furthermore, the front-end inspection header module:

[0021] Camera module: A miniature high-definition camera connected to a drive shaft via a universal joint or miniature servo mechanism, enabling tilt and lateral rotation within a certain range; the camera module is equipped with a removable anti-fog cover.

[0022] Flexible fiber optic illumination module: Several optical fibers are distributed around the camera module, and a focusing lens is set at the end of the optical fiber, which can provide uniform and high-brightness illumination in the narrow oral cavity environment;

[0023] Auxiliary operation pipeline: It can integrate functions such as spraying, rinsing or negative pressure suction. By connecting to an external storage tank or suction device, it can complete the local spraying of medicine or the removal of secretions during the inspection process.

[0024] Wired or wireless transmission module: transmits image data captured by the camera to an external display terminal, and can be selected in wired or wireless mode.

[0025] Furthermore, the external display and control module:

[0026] Display screen: Real-time images of the inside of the throat captured by the camera. Grids or measuring rulers can be overlaid on the screen to help doctors locate lesions.

[0027] Control software: Parameters such as light source brightness, camera rotation range, and spray / suction rate of auxiliary pipes can be set on handheld devices or external terminals;

[0028] Data storage and sharing module.

[0029] Furthermore, the data storage and sharing module can store images or video data during the examination process locally or upload them to the hospital's internal network for subsequent diagnosis or remote consultation.

[0030] Furthermore, the method for checking the header module at the front end is as follows:

[0031] The doctor holds the handle module and gently inserts the front examination head into the mouth; the camera module begins to collect images of the oral cavity and pharyngeal area in real time, and transmits the data to an external display device via wires or a wireless transmission module.

[0032] Because the camera module is connected to the drive shaft assembly, it can achieve a certain range of pitch and left and right rotation under the drive of the universal joint or micro servo mechanism; fine adjustments can be made using the knob on the handle or the button on the control panel to make the camera aim at the throat area to be observed.

[0033] Another object of the present invention is to provide an examination device and method for otolaryngological throat examination, comprising:

[0034] Step 1, Powering on and setting parameters:

[0035] The doctor turns on the device and sets the camera tilt angle range, light source brightness, and expected functions of the auxiliary operation tube through the control panel or external control software.

[0036] Step 2, insert for oral positioning:

[0037] Gently insert the examination head into the mouth while observing the real-time image on the display screen. Use the control buttons or knobs on the handle to fine-tune the camera angle and find the optimal field of view.

[0038] Step 3, Observe from multiple angles:

[0039] If it is necessary to observe certain suspicious lesions closely or view them from different angles, the drive shaft assembly can be used to drive the camera to move up, down, left, and right to obtain a more comprehensive image;

[0040] Step 4, auxiliary operations:

[0041] When local anesthesia or medication spray is required for the throat, the medication is sprayed into the throat through an auxiliary tube;

[0042] If a lot of mucus or secretions are found in the patient's throat, the irrigation mode can be switched to, and saline or disinfectant can be injected through the auxiliary tube to rinse the throat. The excess liquid can be drained by using the negative pressure suction function.

[0043] Step 5, Image Acquisition and Processing:

[0044] The camera transmits the captured images to an external display screen or terminal in real time; doctors can take photos or videos as needed, and enlarge, annotate, or measure the images.

[0045] Step 6, End the inspection and data storage:

[0046] After the examination is completed, the examination head will be slowly removed, and the device will be cleaned and disinfected. At the same time, the examination images or videos can be stored on a local memory card or uploaded to the hospital server for subsequent diagnosis or remote consultation. Beneficial effects

[0047] Based on the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solution to be protected by this invention are as follows:

[0048] First, this invention proposes an examination device for throat examination in otolaryngology. By integrating an adjustable-angle miniature camera module, a flexible fiber optic lighting system, and multifunctional auxiliary components into the device, it helps doctors flexibly adjust the observation angle during the examination and realize spraying, rinsing, or suctioning operations on the throat area.

[0049] 1. Simpler operation and improved comfort

[0050] Because this invention uses an adjustable-angle camera module and an ergonomic handle design, doctors only need to make slight adjustments to the control buttons or knobs on the handle to achieve precise positioning and angle changes of the camera. This effectively reduces the excessive demands on the doctor's hand-eye coordination and significantly reduces the vomiting reflex or discomfort caused by overstimulation in patients.

[0051] 2. Wide field of view and clear image.

[0052] By arranging multiple flexible optical fibers around the camera module, combined with a high-brightness LED or laser light source, stable and uniform illumination can be provided in the confined oral cavity environment, avoiding the problems of vignetting or overexposure that are common with traditional lighting methods. Furthermore, the camera's movable structure allows doctors to observe the target area from multiple angles, making it particularly suitable for areas such as the vocal cords and pyriform fossa that are difficult to fully examine using traditional methods.

[0053] 3. Integrate auxiliary functions to reduce equipment redundancy.

[0054] This invention incorporates multi-functional channels for spraying, rinsing, and negative pressure suction during the examination of the head. Doctors can directly perform procedures such as spraying anesthetic solutions and clearing secretions during the examination without the need for separate nebulizers or suction devices. This multi-functional integrated design not only reduces the number of medical devices but also saves space in the operating room or examination room, improving work efficiency.

[0055] 4. Data recording and sharing are more convenient.

[0056] Through the wired or wireless data transmission module of this invention, images or videos during the examination process can be directly displayed on an external display terminal and stored in real time or uploaded to the network. This not only facilitates doctors to make immediate judgments during the examination but also provides rich image data support for subsequent case discussions and remote consultations.

[0057] 5. Enhanced safety and durability

[0058] All materials used in this device meet medical standards, with smooth surfaces that are easy to sterilize. The anti-fog cover on the camera module and the insulation protection of the flexible optical fiber contribute to improving the device's durability and safety. Furthermore, the design takes into account minimizing patient discomfort and reducing cross-infection between medical staff and patients. All parts of the device are detachable and autoclaved, extending its service life and raising medical safety standards.

[0059] 6. Adaptable to various clinical scenarios

[0060] Because this invention employs a modular structure, the camera, light source, and auxiliary tubing system can be flexibly replaced or upgraded to meet different clinical needs. For example, in pediatrics, a smaller-diameter examination head assembly can be used, along with a low-brightness light source, to reduce stimulation to young children; while in examinations of adult or elderly patients, a higher-resolution camera module can be selected for more accurate assessment of lesion details.

[0061] In summary, this invention represents a significant technological advancement over existing technologies. It provides doctors with clearer and more comprehensive images of the larynx without increasing patient discomfort. Furthermore, its integrated auxiliary functions enhance examination efficiency and safety, meeting the urgent needs of modern otolaryngology for minimally invasive, visualized, and highly efficient examination methods. The application of this invention is expected to significantly reduce misdiagnosis and missed diagnosis rates in clinical diagnosis, while also lessening the burden on both doctors and patients, demonstrating broad promotional value and application prospects.

[0189] Data storage and sharing module: It can store images or video data during the examination locally or upload them to the hospital's internal network for subsequent diagnosis or remote consultation.

[0190] II. System Structure and Methodological Steps

[0191] (1) System architecture setup:

[0192] 1. The grip module is designed as a hollow cavity that can accommodate the motor drive and transmission shaft assembly, with reserved positions for control buttons on the surface;

[0193] 2. Install a universal joint or miniature servo mechanism on the front-end inspection head and connect it to the drive shaft assembly to enable multi-angle rotation of the camera;

[0194] 3. Distribute several flexible optical fibers evenly around the camera module, and install a focusing lens or a diffuser lens at the end of the optical fiber to ensure that the illumination area covers the entire pharyngeal cavity;

[0195] 4. Reserve one or more auxiliary operation pipes on the outside of the camera module and connect them to an external liquid storage tank or negative pressure suction device through flexible hoses;

[0196] 5. Integrate a data transmission channel (wired or wireless) into the handle or inspection head to transmit images to an external display device in real time.

[0197] (2) Method steps:

[0198] 1. Power-on and parameter settings: The doctor turns on the device and sets the camera tilt angle range, light source brightness, and expected functions of the auxiliary operation tube (spraying / rinsing / suction, etc.) through the control panel or external control software.

[0199] 2. Insertion into the oral cavity for positioning: Gently insert the examination head into the oral cavity while observing the real-time image on the display screen. Use the control buttons or knobs on the handle to fine-tune the camera angle and find the optimal field of view.

[0200] 3. Multi-angle observation: If it is necessary to observe certain suspicious lesions at close range or view them from different sides, the drive shaft assembly can be used to drive the camera to move up, down, left, and right to obtain a more comprehensive image;

[0201] 4. Auxiliary Operations:

[0202] When local anesthesia or medication spray is required for the throat, the medication is sprayed into the throat through an auxiliary tube;

[0203] If a lot of mucus or secretions are found in the patient's throat, the irrigation mode can be switched to, and saline or disinfectant can be injected through the auxiliary tube to rinse the throat. The excess liquid can be drained by using the negative pressure suction function.

[0204] 5. Image Acquisition and Processing: The camera transmits the acquired images to an external display screen or terminal in real time; doctors can take photos or videos as needed, and enlarge, annotate, or measure the images;

[0205] 6. End of Examination and Data Storage: After the examination is completed, the examination head is slowly removed, and the device is cleaned and disinfected. At the same time, the examination images or videos can be stored on a local memory card or uploaded to the hospital server for subsequent diagnosis or remote consultation.

[0206] When a doctor is preparing to perform a throat examination, the device can be powered via the battery or wired power interface within the main unit module. The control panel on the handle module allows for initial parameter settings for camera rotation, light source brightness, and auxiliary operation tube functions (such as spraying, rinsing, and suction).

[0207] Through the drive shaft assembly inside the main frame, the device can transmit the doctor's manual rotation or motor drive signal to the front examination head, preparing for subsequent camera angle adjustments.

[0208] Front-end check header insertion and positioning

[0209] The doctor holds the handle module and gently inserts the front examination head into the mouth. At this moment, the camera module begins to capture real-time images of the oral cavity and pharyngeal region, and transmits the data to an external display device via wires or a wireless transmission module.

[0210] Because the camera module is connected to the drive shaft assembly, it can achieve a certain range of pitch and lateral rotation under the drive of a universal joint or a micro servo mechanism. Doctors can make fine adjustments using the knobs on the handle or the buttons on the control panel to aim the camera at the desired area of ​​the throat.

[0211] Lighting and Image Acquisition

[0212] Several flexible optical fibers are evenly distributed around the camera module, and a focusing lens or a diffuser lens is installed at the end of the optical fiber, which can provide uniform and high-brightness illumination in the narrow oral cavity environment.

[0213] The control panel or external control software can adjust the brightness of the light source, allowing doctors to obtain appropriate illumination at different depths and angles, thereby reducing glare or shadow areas and improving image clarity.

[0214] The camera module is equipped with a detachable anti-fog cover, which can reduce lens fogging caused by the temperature and humidity of the patient's mouth during the examination and ensure image clarity.

[0215] During the examination, if the doctor needs to spray anesthetic or disinfectant on the local area of ​​the throat, it can be connected to an external storage tank through an auxiliary operating pipe, and the spraying can be precisely controlled by using the start / stop switch on the control panel.

[0216] When excessive secretions or mucus are found in the throat, the doctor can switch to the irrigation mode, inject saline solution into the target area through the same tube, and simultaneously activate the negative pressure suction function to drain the irrigation fluid and secretions, ensuring a clear view.

[0217] Because the auxiliary operation pipes are located adjacent to the camera module, the camera can monitor the local operation effect in real time during spraying, rinsing or suction, avoiding operational errors or secondary pollution.

[0218] Image data transmitted via wires or wireless transmitters allows doctors to view the inside of a patient's throat in real time on an external display screen. The display screen can overlay auxiliary information such as grids and rulers to help doctors more accurately locate lesions.

[0219] If it is necessary to observe a certain part from multiple angles, the doctor can readjust the angle or position of the camera module and obtain updated images on the display screen in real time.

[0220] In addition to adjusting the brightness of the light source and the rotation angle of the camera, the control software can also control the spraying / suction rate of the auxiliary pipeline and record or capture images or videos during the inspection process.

[0221] Images or videos generated during the examination can be stored in real time on a local storage card or uploaded to the hospital's internal system via the network for later viewing or medical record archiving.

[0222] For complex cases requiring expert consultation, the network connectivity provided by this device can be used to share real-time images or recorded files with a remote professional team for discussion and diagnosis.

[0223] After the examination, the doctor can slowly remove the examination head and perform routine cleaning and disinfection of the camera module and external accessories. Because the front-end examination head is detachable, the cleaning and maintenance process is much simpler.

[0224] The hoses connecting the auxiliary operating pipeline to the storage tank and negative pressure suction device can also be replaced or sterilized at high temperature to prevent cross-infection and extend the service life of the device.

[0225] In summary, this device utilizes the main frame module in conjunction with the front-end examination head to achieve visualized examination and assisted operation of the pharynx; relying on flexible fiber optic illumination and an adjustable-angle camera module, it enables doctors to obtain clear, multi-angle images even in confined environments; through the auxiliary operation channels, it further integrates spraying, rinsing, and suction functions, improving examination efficiency and safety; while the external display and control system provides a convenient operating interface, data storage, and remote consultation support, making the entire examination process more intelligent and user-friendly.
