[0001] This utility model relates to the field of laryngoscope technology, specifically to an angle-adjustable support laryngoscope. Background Technology

[0002] A support laryngoscope is a type of microlaryngoscopy. Its structure involves connecting a direct laryngoscope to a support frame that can be adjusted in height and distance, or placing the support frame on a chest support tray, so that the laryngoscope is more securely fixed, allowing the surgeon to operate surgical instruments with both hands simultaneously.

[0003] A search revealed that the patent, CN216652249U, entitled "A Utility Model of a Visual Support Laryngoscope," includes a support frame, a video laryngoscope, and a laryngoscope tube. Research and analysis revealed that although it can be matched with video laryngoscopes of different shapes and can directly use existing video laryngoscopes, and is ingeniously designed, simple in structure, easy to use, and inexpensive, making it very worthy of promotion and application in practical work, it still has the following shortcomings to some extent.

[0004] For example, the laryngoscope tube cannot be adjusted up and down or forward and backward. The direction of the laryngoscope tube used to support the laryngoscope is fixed. During use, the inner end of the laryngoscope tube cannot be adjusted up and down or forward and backward. This makes it inconvenient for personnel to support the patient's larynx by controlling the bending angle of the laryngoscope tube, affecting the personnel's observation. At the same time, it is inconvenient to extract blood seepage and smoke generated during the suction procedure. In order to solve the above technical problems, we have designed an angle-adjustable laryngoscope. Utility Model Content

[0022] Please see Figures 1-6 An adjustable laryngoscope includes a laryngoscope tube 1. Silicone strips 2 are glued to the top and rear of the laryngoscope tube 1. An elastic steel strip 5 is fixedly connected to the inner cavity of the silicone strips 2. Mounting plates 8 are fixedly connected to the top and rear of the inner cavity of the laryngoscope tube 1. A miniature camera 7 and a mounting hole 20 are bolted to the left side of the mounting plate 8. The mounting hole 20 allows for the placement of an optical fiber for laser surgery during operation. Adjustment mechanisms 3 are fixedly connected to the top and right sides of the inner cavity of the laryngoscope tube 1. A suction tube 19 is fixedly connected to the bottom of the inner cavity of the laryngoscope tube 1. The right side of the suction tube 19 extends to the bottom of the laryngoscope tube 1. An adjustment frame 4 is fixedly connected to the right side of the top of the laryngoscope tube 1. A support frame 6 is fixedly connected to the top of the adjustment frame 4. The miniature camera 7 allows for independent filming, enabling personnel to easily film the larynx as the laryngoscope tube 1 bends up and down.

[0023] Please see Figure 2 The laryngoscope tube 1 includes a tube body 12. A connecting sleeve 11 is fixedly connected to the left side of the tube body 12. A support sleeve 10 is fixedly connected to the left side of the connecting sleeve 11. Limiting tubes 9 are fixedly connected to the top and rear side of the inner cavity of the support sleeve 10. By setting the connecting sleeve 11, it has the function of flexible connection, which can make two adjacent support sleeves 10 flexiblely connected, so that they can be bent up and down.

[0024] Please see Figure 2 The connecting sleeve 11 is made of medical silicone material, and there are several limiting tubes 9. By setting the limiting tubes 9, the limiting function is provided to prevent the traction ropes 13 on both sides from shifting during movement.

[0025] Please see Figure 4 The adjustment mechanism 3 includes two fixed vertical plates 14, which are respectively fixedly connected to the top and rear of the laryngoscope tube 1. An adjustment screw 16 is threaded through the middle of the right side of the fixed vertical plate 14. A connecting horizontal plate 17 is connected to the right side of the surface of the adjustment screw 16 via a bearing. Limiting slide rods 15 are fixedly connected to the front and rear sides of the left side of the connecting horizontal plate 17. The left side of the limiting slide rod 15 extends through to the left side of the fixed vertical plate 14 and is fixedly connected to a traction rope 13. The left side of the traction rope 13 is fixedly connected to the mounting vertical plate 8. By setting the limiting slide rod 15, it has a guiding function, which allows the connecting horizontal plate 17 to move left and right when the adjustment screw 16 is rotated, so as to facilitate the pulling of the traction rope 13.

[0026] Please see Figure 4 The surface of the limiting slide bar 15 is slidably connected to the fixed vertical plate 14. The left and right sides of the adjusting screw 16 are respectively fixedly connected to the limiting baffle and the rotating plate 18. By setting the baffle, it has the function of preventing detachment and can prevent the adjusting screw 16 from detaching from the fixed vertical plate 14 during rotation.

[0027] Please see Figure 3 and Figure 6 There are five silicone strips 2 and five elastic steel strips 5, which are distributed at the top and back of the laryngoscope tube 1. The left side of the suction tube 19 is fixedly connected to the suction funnel 21. By setting the silicone strips 2, a protective function is provided to prevent the elastic steel strips 5 from causing damage to the patient's larynx. By setting the suction funnel 21, it is convenient to collect the liquid.

[0028] During use, the operator securely attaches the silicone strip 2 to the top and rear of the tube 12. The elastic steel strip 5 inside the silicone strip 2, under its own elastic force, rolls up from the left and rear sides, causing the leftmost side of the laryngoscope tube 1 to bend upwards and backwards. At this time, the traction ropes 13 at the top and rear pull on the mounting vertical plates 8 at the top and rear of the laryngoscope tube 1, respectively, keeping the laryngoscope tube 1 in a balanced state. After inserting the laryngoscope tube 1 into the patient's larynx, the operator rotates the top adjusting screw 16 counterclockwise. Because the surface of the adjusting screw 16 is threadedly connected to the fixing vertical plate 14, the adjusting screw 16 moves to the left, causing the connecting horizontal plate 17 on the surface of the adjusting screw 16 to move to the left as well. The traction ropes 13 on both sides also move to the left, so that the left side of the laryngoscope tube 1 bends upward under the action of the elastic steel strip 5. When it bends to the appropriate angle, stop rotating the adjusting screw 16. Conversely, if the adjusting screw 16 is rotated clockwise, the traction rope 13 will be pulled to the right and the left side of the laryngoscope tube 1 will bend downward. Similarly, according to the above operation, rotating the adjusting screw 16 on the rear side can bend the left side of the laryngoscope tube 1 forward or backward. In this way, the laryngoscope tube 1 can be adjusted up and down and forward and backward, which makes it easier to support the patient's larynx and make it easier for medical staff to see. At the same time, the right side of the suction tube 19 is connected to the suction device, so that the blood, exudate and smoke generated during the operation can be suctioned out.

[0029] In summary, this adjustable-angle laryngoscope, through the coordinated use of the laryngoscope tube 1, silicone strip 2, adjustment mechanism 3, elastic steel strip 5, miniature camera 7, mounting plate 8, and suction tube 19, solves the problems of the tube being unable to be adjusted up and down or forward and backward, which makes it difficult for personnel to view the patient's larynx, resulting in poor practicality and the inability to extract blood, exudate, smoke, and gas.
