Technical Field

[0001] This utility model relates to the field of arytenoid laryngeal forceps, specifically a arytenoid laryngeal forceps for the posterior cartilage of the vocal cords. Background Technology

[0002] Laryngeal forceps are common emergency medical equipment used to maintain an open airway, prevent the tongue from falling back, and allow air to enter the lungs. They typically consist of two handles and two forceps heads. Generally, laryngeal forceps are made of non-irritating plastic or rubber to avoid injury to the patient.

[0003] The forceps head and handle are fixed structures. When the shape of the foreign object in a person's ear, nose and throat is more complicated, the conventional forceps head may not be able to grasp the foreign object well, and other sizes of foreign body forceps need to be used, which increases the cost. Secondly, placing multiple instruments in the instrument tray will cause the tray to be messy after use.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, before using the laryngeal forceps, the forceps head is positioned at the posterior cartilage of the vocal cords. When in use, the power unit 4 operates, pressing down the movable handle 41 to rotate the rotating component 42 on the rotating rod 43, providing power for the forceps head to grip. Simultaneously, the elastic component 44 provides a rebound force when the movable handle 41 is released, facilitating subsequent reuse. When the connecting component 5 operates, the rotating component 42, through the spherical groove 51, drives the spherical block 52, causing the pull tube 53 to move to the right. The pull tube 53 then drives the top block 54 to slide within the guide rail 55, facilitating connection between the power unit 4 and the opening / closing component 7. When the opening / closing component 7 operates, the top block 54, through the positioning component 8, drives the connecting component 9 downwards. The positioning plate 77 drives the connecting rod 76 to move. The connecting rod 76, through the positioning rod 75, causes the fixing plate 74 to rotate. The fixing plate 74 drives the movable pliers head 72 to rotate on the fixing rod 73, thereby cooperating with the fixed pliers head 71 to clamp foreign objects. When the pliers head needs to be replaced, the positioning component 8 works, pressing down the connecting tube 6. Through the connecting piece 9, the cross block 81 is driven to insert into the cross groove 82. At the same time, the spring 84 pushes the positioning block 85 to cooperate with the positioning groove 86, fixing the position of the pliers head. At the same time, the cross block 81 and the cross groove 82 cooperate to prevent the pliers head from rotating during use, making it convenient to replace the pliers head and preventing the confusion caused by multiple throat pliers after use.
