Abstract
Description
Technical Field
[0001] This invention relates to the field of movable laryngoscope technology, and more particularly to a movable laryngoscope with supplemental lighting function. Background Technology
[0002] In the fields of anesthesia, emergency care, and intensive care, catheters are typically inserted through the mouth and mechanical ventilation is used to ensure normal breathing. Catheterization is particularly essential in anesthesia. Currently, hospitals commonly use guided anesthesia intubation before surgery, which is primarily performed using a video laryngoscope. During the procedure, the surgeon can clearly see the catheter tip with the help of the video laryngoscope. Once the glottis is exposed, the catheter is simply advanced along the guide groove to complete the intubation.
[0003] Because of individual differences in laryngeal structure, various variations exist during intubation. Current movable laryngoscopes cannot adjust the direction of the insertion tube during intubation. In cases with a high glottis or a small pharyngeal cavity, glottic exposure is extremely difficult, making tube insertion challenging. Even after glottic exposure, the inability to adjust the tube's direction prevents alignment of the tube tip with the glottis, forcing the surgeon to manually intubate, thus impacting success rate and surgical efficiency. Adjusting the tube's direction can cause discomfort due to its movement, and the movement of the movable laryngoscope's lens during examination can irritate the patient's larynx, leading to coughing or discomfort, especially in highly sensitive areas of the larynx. Summary of the Invention
[0004] The purpose of this invention is to address the problems existing in the prior art by proposing a movable laryngoscope with supplemental lighting function that can adjust the direction of the catheter.
[0005] The technical solution of the present invention: A movable laryngoscope with supplemental lighting function, comprising a handle, a display screen rotatably mounted on the handle, and a laryngoscope fixedly mounted on the bottom of the handle, and further comprising:
[0006] A guide tube is fixedly installed on a laryngoscope. One end of the guide tube is provided with an input port for inserting a catheter, and the other end of the guide tube is provided with a steering mechanism that adjusts the end of the catheter to point towards the glottis.
[0007] An adjustment mechanism is located on one side of the laryngoscope and above the steering mechanism. A supplementary light and a camera are fixedly mounted on the adjustment mechanism, which adjusts the illumination direction of the supplementary light and the camera.
[0008] Optionally, a battery is fixedly installed inside the handle, and a switch button is fixedly installed on the surface of the handle.
[0009] Optionally, the laryngoscope is fixedly equipped with an epiglottic supplement light and an epiglottic camera at its front end.
[0010] Optionally, the steering mechanism includes a guide block fixedly installed at one end of the guide tube, a miniature electric telescopic rod fixedly installed around the guide block, and a drive plate fixedly installed on the telescopic shaft of the miniature electric telescopic rod. The guide block has a through hole communicating with the guide tube, and the drive plate is located in the through hole.
[0011] Optionally, the laryngoscope is provided with a mounting groove, and the adjustment mechanism includes an electric telescopic rod and a support column fixed in the mounting groove. A first adjustment plate is rotatably mounted on the support column, and a connecting rod is rotatably mounted on the telescopic shaft of the electric telescopic rod. The other end of the connecting rod is rotatably connected to the first adjustment plate. A second adjustment plate is rotatably mounted on the first adjustment plate, and a motor is fixedly mounted on one side of the first adjustment plate. The output shaft of the motor is fixedly connected to the second adjustment plate.
[0012] Optionally, the supplementary light and camera are fixedly mounted on the second adjustment plate, and an anti-fog baffle is fixedly installed in the mounting slot.
[0013] Optionally, a defogging mechanism is also included. The defogging mechanism is installed on the laryngoscope and located on one side of the anti-fog baffle. The defogging mechanism removes water mist that appears on the anti-fog baffle. The defogging mechanism includes a mounting frame that is slidably installed on the laryngoscope, a miniature electric telescopic rod that is fixedly installed on the laryngoscope, and multiple scrapers that are detachably installed on the mounting frame. The telescopic shaft of the miniature electric telescopic rod is fixedly connected to the mounting frame. The scrapers are provided with connecting holes. The scrapers are absorbent cotton and absorb mucus. The mounting frame is provided with a pin mechanism that inserts into the connecting holes.
[0014] Optionally, the pin mechanism includes multiple sliding holes on the mounting frame, a pin slidably installed in the sliding holes, a drive block fixedly installed on the pin, and a spring provided in the sliding holes, one end of the spring being fixedly connected to the drive block, and the other end of the spring being fixedly connected to the inner wall of the sliding holes.
[0015] Optionally, a drive mechanism for driving the catheter to move at a constant speed is installed inside the guide tube. The drive mechanism includes two drive wheels rotatably installed inside the guide tube, a connecting rod fixedly installed on the laryngoscope, a mounting base fixedly installed on the connecting rod, an electric push rod fixedly installed on the mounting base, a motor base fixedly installed on the telescopic shaft of the electric push rod, a drive motor fixedly installed on the motor base, a first friction plate fixedly installed on the output shaft of the drive motor, a drive rod fixedly installed on the drive wheels and passing through one side of the laryngoscope and extending to the outside of the laryngoscope, a pulley fixedly installed on the drive rod, a second friction plate fixedly installed on one of the pulleys and located on one side of the first friction plate, and a transmission belt provided on the two pulleys. A pressure sensor is fixedly installed on the first friction plate, and a pressure block is fixedly installed on the second friction plate. Multiple transmission wheels are installed inside the guide tube.
[0016] Optionally, the laryngoscope is equipped with a spacing adjustment mechanism that drives one of the drive wheels to move. The spacing adjustment mechanism includes a pull plate rotatably mounted on the outer drive wheel, a miniature electric push rod fixedly mounted on the guide tube and fixedly connected to the pull plate, a support plate fixedly mounted on the guide tube, two mounting blocks fixedly mounted on the support plate, a support telescopic rod fixedly mounted on the mounting blocks, an adjustment seat fixedly mounted on the support telescopic rod, an adjustment spring fixedly mounted on the mounting blocks and fixedly connected to the adjustment seat, and tension wheels rotatably mounted on the two adjustment seats. The tension wheels abut against the transmission belt.
[0017] Compared with the prior art, the present invention has the following beneficial technical effects: by adjusting the camera's shooting image through the adjustment mechanism, it can be adjusted to the optimal position for shooting the glottis without shaking the handle, so that the position of the laryngoscope in the larynx does not change. This can avoid the laryngoscope's movement from stimulating the patient's larynx, causing coughing or discomfort, and can reduce the difficulty of inserting the catheter. This allows novice doctors to compensate for the discomfort caused by their lack of experience when treating patients, and reduces the pain of patients during treatment.
[0018] Furthermore, the direction of the catheter tip is adjusted by the guide tube and the steering mechanism to align the catheter with the glottis. Once aligned, the catheter can be directly inserted into the glottis. When adjusting the catheter, it rotates inside the guide tube, preventing the moving catheter from directly contacting the larynx and thus preventing irritation to the patient's larynx. Adjusting the direction of the catheter tip avoids the problem of difficulty in inserting the catheter into the glottis in patients with excessively high glottis or small pharyngeal cavities, thus preventing catheter insertion difficulties and improving the success rate of intubation and surgical efficiency.
[0019] Furthermore, during intubation, a drive motor rotates two drive wheels. The friction between the drive wheels and the catheter allows the catheter to move smoothly. When the catheter encounters resistance, the first and second friction plates slip, preventing the catheter from moving further and allowing it to move at a constant speed. This avoids damage to the trachea and surrounding tissues, prevents mechanical damage to the vocal cords due to excessively fast intubation speed, and avoids increased discomfort and anxiety for the patient due to excessively slow intubation speed.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] Example 1
[0034] See Figure 1-2 As shown, the present invention proposes a movable laryngoscope with supplemental lighting function, including a handle 1, a display screen 4 rotatably mounted on the handle 1, and a laryngoscope 2 fixedly mounted on the bottom of the handle 1. A battery is fixedly installed inside the handle 1, and a switch button 101 is fixedly installed on the surface of the handle 1. An epiglottic supplemental light 3 and an epiglottic camera 301 are fixedly installed at the front end of the laryngoscope 2. Holding the handle 1, the laryngoscope 2 is inserted along the midline of the oral cavity. The epiglottic supplemental light 3 illuminates the front end of the laryngoscope 2. The epiglottic camera 301 captures the image inside the oral cavity and transmits it to the display screen 4 in real time. By observing the image on the display screen 4, the laryngoscope 2 is slowly pushed forward. When the epiglottis is seen on the display screen 4, the laryngoscope 2 is gently lifted, so that the front end of the laryngoscope 2 is pulled upward to lift the epiglottis. At this time, the glottis is exposed, and the best glottic field of view can be obtained.
[0035] like Figure 1-6As shown, the movable laryngoscope also includes an adjustment mechanism located on one side of the laryngoscope 2 and above the steering mechanism. A supplementary light 705 and a camera 706 are fixedly mounted on the adjustment mechanism. The adjustment mechanism adjusts the illumination direction of the supplementary light 705 and the camera 706. The laryngoscope 2 has a mounting groove. The adjustment mechanism includes an electric telescopic rod 702 and a support column 701 fixedly mounted in the mounting groove. A first adjustment plate 703 is rotatably mounted on the support column 701. A connecting rod 708 is rotatably mounted on the telescopic shaft of the electric telescopic rod 702. The other end of the connecting rod 708... One end is rotatably connected to the first adjusting plate 703. A second adjusting plate 704 is rotatably mounted on the first adjusting plate 703. A motor 707 is fixedly mounted on one side of the first adjusting plate 703. The output shaft of the motor 707 is fixedly connected to the second adjusting plate 704. A supplementary light 705 and a camera 706 are fixedly mounted on the second adjusting plate 704. An anti-fog baffle 7 is fixedly installed in the mounting slot. When the front end of the laryngoscope 2 is pulled upward to expose the epiglottis, the camera 706 captures the position of the glottis and transmits the image to the display screen 4. The position of the glottis is observed on the display screen 4. The position is determined because everyone's laryngeal structure is different. When the glottis is too high or too low, the camera cannot provide a clear glottis position. At this time, the electric telescopic rod 702 is activated to drive the connecting rod to rise or fall, which in turn drives the first adjusting plate 703 to rotate around the support column 701, which in turn drives the second adjusting plate 704 to rotate in the left and right directions, which in turn drives the camera 706 and the supplementary light 705 to rotate, thereby adjusting the shooting position. By starting the motor 707, the second adjusting plate 704 is driven to rotate, which in turn drives the camera 706 and the supplementary light 705 to rotate, thereby changing the shooting image of the camera 706 in the vertical direction, and thus adjusting to the best position for shooting the glottis. This process does not require shaking the handle 1, so the position of the laryngoscope 2 in the larynx will not change, thus avoiding the stimulation of the patient's larynx by the movement of the laryngoscope 2, which may cause coughing or discomfort. It can reduce the difficulty of inserting the catheter, and make up for the discomfort caused by the lack of experience when novice doctors treat patients, reducing the pain of patients during treatment.
[0036] Furthermore, such as Figure 1-3As shown, the movable laryngoscope also includes a guide tube 5, which is fixedly mounted on the laryngoscope 2. One end of the guide tube 5 has an input port 501 for inserting a catheter, and the other end of the guide tube 5 has a steering mechanism. The steering mechanism adjusts the end of the catheter to point towards the glottis. The steering mechanism includes a guide block 502 fixedly mounted on one end of the guide tube 5, miniature electric telescopic rods 6 fixedly mounted around the guide block 502, and a drive plate 601 fixedly mounted on the telescopic shaft of the miniature electric telescopic rods 6. The guide block 502 has a through hole communicating with the guide tube 5, and the drive plate 601 is located in the through hole. After gently lifting the laryngoscope 2, the catheter is inserted into the guide tube 5 through the input port 501. The catheter will enter the front of the glottis along the inside of the guide tube 5. By observing the image on the display screen 4 and controlling the four miniature electric telescopic rods 6, the laryngoscope can be controlled. The drive plate 601 is moved to move the catheter, thereby adjusting the direction of the catheter head to align the catheter with the glottis. When the catheter is manually rotated, it rotates inside the guide tube 5, preventing the moving catheter from directly contacting the larynx. The guide tube 5, which is in direct contact with the larynx, is fixed, thus preventing irritation of the patient's larynx and causing coughing or discomfort. The direction of the catheter head is adjusted by the drive plates 601 on all four sides. After adjustment, the catheter can be directly inserted into the glottis, avoiding the problem of difficulty in inserting the catheter into the glottis in patients with excessively high glottis or small pharyngeal cavities. This prevents the catheter from being difficult to insert, avoids the need for manual intubation by doctors, which affects the success rate of intubation and surgical efficiency, and avoids repeated rotation of the trachea in the larynx, which could damage the larynx.
[0037] Further, such as Figure 3 and Figure 5 as well as Figure 6As shown, the laryngoscope also includes a defogging mechanism, which is installed on the laryngoscope 2 and located on one side of the anti-fog baffle 7. The defogging mechanism removes water mist that appears on the anti-fog baffle 7. The defogging mechanism includes a mounting frame 8 slidably installed on the laryngoscope 2, a miniature electric telescopic rod 802 fixedly installed on the laryngoscope 2, and multiple scrapers 801 detachably installed on the mounting frame 8. The telescopic shaft of the miniature electric telescopic rod 802 is fixedly connected to the mounting frame 8. The scrapers 801 are provided with connection holes, and the mounting frame 8 is provided with... The connecting hole insertion mechanism includes multiple sliding holes 804 on the mounting frame 8, a pin 805 slidably installed in the sliding hole 804, a drive block 803 fixedly installed on the pin 805, and a spring 806 installed in the sliding hole 804. One end of the spring 806 is fixedly connected to the drive block 803, and the other end of the spring 806 is fixedly connected to the inner wall of the sliding hole 804. The scraper 801 is absorbent cotton, which absorbs mucus. After the laryngoscope 2 enters the oral cavity, the anti-fog baffle 7... Water vapor can easily form on the camera, and oral secretions and mucus can also affect the anti-fog baffle 7. Water vapor will condense on the camera surface, affecting the camera's imaging effect and causing blurry images. Water vapor will also obstruct the doctor's view, affecting the doctor's judgment and operation of the oral cavity. Oral secretions and mucus will adhere to the surface of the anti-fog baffle 7, resulting in a decrease in image quality and affecting the accuracy of diagnosis. The miniature electric telescopic rod 802 drives the mounting frame 8 to move back and forth, thereby driving the scraper 801 on the anti-fog baffle. The scraper 801 is moved on the mounting frame 8 to wipe away the water mist. The scraper 801 is made of absorbent cotton and can absorb the viscous liquid. When replacing the scraper 801, the drive block 803 is pulled to move the pin 805 and pull the pin 805 out of the connection hole on the scraper 801. Then, the unused scraper 801 is placed on the mounting frame 8 and the connection hole on the scraper 801 is aligned with the pin 805. The drive block 803 is released and the scraper 801 is fixed by the action of the spring 806.
[0038] Working Principle: Holding handle 1, insert laryngoscope 2 along the midline of the oral cavity. Epiglottic supplemental light 3 illuminates the front end of laryngoscope 2. The epiglottic camera 301 captures the image inside the oral cavity. By observing the image on display screen 4, slowly advance laryngoscope 2. Once the epiglottis is visible on display screen 4, gently lift laryngoscope 2, causing the front end of laryngoscope 2 to pull the epiglottis upward, exposing the glottis. After the glottis is exposed, camera 706 captures the position of the glottis and transmits the image to display screen 4. By observing display screen 4, the position of the glottis is determined. Because the laryngeal structure varies from person to person, if the glottis is too high or too low, activate electric telescopic rod 702 to raise or lower the connecting rod, thereby causing the first adjusting plate 703 to rotate around the support column 701. This, in turn, causes camera 706 and supplemental light 705 to rotate, thus adjusting the position in the left and right directions of the image capture. Activating motor 707 drives the second adjusting plate... The plate 704 rotates, thereby changing the vertical shooting image of the camera 706 and adjusting it to the optimal position for shooting the glottis. This process does not require shaking the handle 1, so the position of the laryngoscope 2 in the larynx does not change, thus avoiding stimulation of the patient's larynx by moving the laryngoscope 2. Then, the catheter is inserted into the guide tube 5 through the inlet port 501. The catheter will enter the front of the glottis along the inside of the guide tube 5. By controlling the four micro electric telescopic rods 6 to push the drive plate 601 to move, the direction of the catheter head is adjusted so that the catheter is aligned with the glottis. Then the catheter can be directly inserted into the glottis, thus preventing coughing or discomfort caused by adjusting the position of the catheter and laryngoscope in the glottis. This reduces the difficulty of inserting the catheter and avoids the difficulty of inserting the catheter into the glottis in patients with a high glottis or a small pharyngeal cavity. It also prevents the catheter from being difficult to insert and avoids the doctor having to insert the catheter manually, which affects the success rate of intubation and the efficiency of the operation.
[0039] Furthermore, the miniature electric telescopic rod 802 drives the scraper 801 to move on the anti-fog baffle 7, thereby wiping away the water mist. The scraper 801 is absorbent cotton, which can absorb mucus, preventing water mist from appearing on the anti-fog baffle 7 and preventing oral secretions from affecting the anti-fog baffle 7, thus affecting the imaging effect of the camera, preventing image blurring, and avoiding affecting the doctor's judgment and operation of the oral cavity.
[0040] Example 2
[0041] like Figure 8-11As shown, based on Embodiment 1, a drive mechanism for driving the duct to move at a constant speed is installed inside the guide tube 5. The drive mechanism includes two drive wheels 9 rotatably installed inside the guide tube 5, a connecting rod 901 fixedly installed on the laryngoscope 2, a mounting base 902 fixedly installed on the connecting rod 901, an electric push rod 903 fixedly installed on the mounting base 902, a motor base 904 fixedly installed on the telescopic shaft of the electric push rod 903, a drive motor 905 fixedly installed on the motor base 904, and an output shaft fixedly installed on the drive motor 905. The guide tube 5 includes a first friction plate 906, a drive rod 909 fixedly mounted on the drive wheel 9, passing through one side of the laryngoscope 2 and extending to the outside of the laryngoscope 2, a pulley 908 fixedly mounted on the drive rod 909, a second friction plate 907 fixedly mounted on one of the pulleys 908 and located on one side of the first friction plate 906, and a transmission belt 910 disposed on the two pulleys 908. A pressure sensor 912 is fixedly mounted on the first friction plate 906, and a pressure block 911 is fixedly mounted on the second friction plate 907. Multiple transmission wheels 11 are installed inside the guide tube 5. The transmission wheels 11 reduce the friction force on the catheter inside the guide tube 5.
[0042] When performing endotracheal intubation using a movable laryngoscope, controlling the intubation speed is crucial. Intubation that is too rapid may cause mechanical damage to the vocal cords. The patient may experience a strong stress response due to the sudden stimulation, leading to increased heart rate and blood pressure. Intubation that is too slow will cause the patient more discomfort and anxiety. Furthermore, unpredictable resistance may be encountered during intubation; forcing insertion can damage the glottis, trachea, and surrounding tissues. Healthcare professionals cannot always maintain perfect control over the force applied during intubation.
[0043] During intubation, the catheter is placed inside the guide tube 5 and positioned between the two drive wheels. Then, the electric push rod 903 is activated, causing the first friction plate 906 to adhere to the second friction plate 907. Based on data detected by the pressure sensor 912, the pressure applied by the first friction plate 906 to the second friction plate 907 can be adjusted. By adjusting the pressure, the maximum torque that the first friction plate 906 and the second friction plate 907 can transmit can be changed. The drive motor 905 is activated, causing the first friction plate 906 to rotate, which in turn causes the second friction plate 907 to rotate. This causes the pulley 908, which is fixedly connected to the second friction plate 907, to rotate. Through the transmission belt 910, both pulleys 908 rotate simultaneously, and through the drive rod 909, drive the drive wheel 9 to rotate. The friction between the drive wheel 9 and the catheter allows the catheter to move smoothly. When the catheter encounters resistance during movement, slippage occurs between the first friction plate 906 and the second friction plate 907, preventing the catheter from continuing to move and avoiding damage to the trachea and surrounding tissues.
[0044] The laryngoscope 2 is equipped with a spacing adjustment mechanism that drives one of the drive wheels to move. The spacing adjustment mechanism includes a pull plate 10 rotatably mounted on the outer drive wheel 9, a miniature electric push rod 1001 fixedly mounted on the guide tube 5 and fixedly connected to the pull plate 10, a support plate 1002 fixedly mounted on the guide tube 5, two mounting blocks 1003 fixedly mounted on the support plate 1002, a support telescopic rod 1004 fixedly mounted on the mounting block 1003, an adjustment seat 1006 fixedly mounted on the support telescopic rod 1004, an adjustment spring 1005 fixedly mounted on the mounting block 1003 and fixedly connected to the adjustment seat 1006, and a tension wheel 1007 rotatably mounted on the two adjustment seats 1006. The tension wheel 1007 abuts against the transmission belt 910.
[0045] When the conduit is placed inside the guide tube 5, the micro electric push rod 1001 is activated, which moves the pull plate 10 and then the drive wheel 9, thereby increasing the distance between the two drive wheels 9. This makes it easier to place the conduit between the two drive wheels 9. When the distance between the two drive wheels 9 changes, the two pulleys 908 will change. At this time, the tension wheel 1007, under the action of the adjusting spring 1005, will push the transmission belt 910 to keep the transmission belt 910 taut, ensuring that the two drive wheels 9 can rotate synchronously.
[0046] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
