[0001] The invention relates to the technical field of medical devices, and in particular to an auxiliary cannula structure for an inhalation anesthesia catheter. Background Art

[0002] After the patient is anesthetized, it is usually necessary to intubate the patient first. Intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. Intubation is a method of inserting a special endotracheal tube through the oral or nasal cavity and into the trachea or bronchus through the glottis, providing the best conditions for airway patency, ventilation and oxygen supply, and airway suction. It is an important measure to rescue patients with respiratory dysfunction.

[0003] Publication number CN116370772A discloses a tracheal tube fixer, including a fixing component, an upper tooth pad is fixedly installed on one side of the fixing component, and a trachea limiting component is movably provided on the bottom of the upper tooth pad, a lower tooth pad is movably connected to the bottom of the trachea limiting component, and a spreading component is fixedly installed on one side of the fixing component.

[0004] The above-mentioned prior art still has some problems: 1. It only fixes the trachea at the patient's lips, but the trachea becomes soft after the guide wire is pulled out, especially after the end away from the lips is connected to the oxygen tube, the entire trachea will be pulled by the gravity of the oxygen tube, causing the trachea to become bent and causing damage to the patient's throat; 2. The overall operation is not convenient enough, especially when the patient needs to pull out the trachea and it is difficult to disassemble, so an auxiliary intubation structure for an inhalation anesthesia catheter is proposed to solve the above problems.

[0021] In summary, the present invention sets a surrounding mechanism so that the clamping arc plate and the surrounding plate surround the outer wall of the trachea, and sets a synchronous fixing mechanism to cooperate with the movement of the surrounding mechanism, so that the clamping plate can clamp the trachea. When the trachea is connected to the oxygen tube, although the weight of the oxygen tube will cause the trachea to bend, the outer wall of the trachea has been clamped and wrapped by the clamping arc plate and the surrounding plate, ensuring that the trachea will remain in a vertical state, thereby not damaging the patient's throat, and it is easy to disassemble without the need for symmetrical operation on both sides.

[0045] In this embodiment, when the sixth gear 28 is meshed with the third arc-shaped rack 30, the fifth gear 29 is driven to rotate through the pulley assembly 27, so that the second rack 25 drives the base 24 to move along the third fixed plate 26, so that the clamping plate 22 can clamp the trachea.

[0046] The specific working principle and method of use of the present invention are explained in detail below: during use, when tracheal intubation is completed, the knob 2 is rotated, and the knob 2 drives the first threaded rod 7 to rotate through the first shaft rod 14, and the first fixed plate 8 drives the displacement slide 12 to move, so that the bottom of the clamping arc plate 5 can be close to the height of the patient's lips, and then the first motor 13 rotates, driving the first gear 9 to rotate so that the first gear 9 drives the first slide rod 3 to move through the first rack 6, thereby driving the clamping arc plate 5 to approach the outer wall of the trachea.

At this time, the diameter of the circle formed by the clamping arc plate 5 and the surrounding plate 31 is set to be larger than the trachea to prevent the trachea from colliding with it during movement, thereby causing the trachea to move. At this time, the clamping arc plate 5 and the two surrounding plates 31 form a slightly open circle to support the side wall of the trachea.

[0048] At the same time, when the sixth gear 28 is meshed with the third arc-shaped rack 30, the fifth gear 29 is driven to rotate through the pulley assembly 27, so that the second rack 25 drives the base 24 to move along the third fixed plate 26, so that the clamping plate 22 can clamp the trachea. At this time, the fixation of the trachea is completed. When the trachea is connected to the oxygen tube, although the weight of the oxygen tube will cause the trachea to bend, the outer wall of the trachea has been clamped and wrapped by the clamping arc plate 5 and the surrounding plate 31, ensuring that the trachea will remain vertical and will not damage the patient's throat.
