DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] Embodiment: A nasal foreign body remover comprises a handle portion 1 having a cavity 2 therein. Figure 1 As shown, the outside of the handle portion 1 has a roller groove 3 connected to the cavity 2; a transmission component 4 is installed in the cavity 2, and the driving end of the transmission component 4 is arranged in the roller groove 3; the front end of the handle portion 1 is symmetrically provided with an extension tube 5, and a rope body 6 is passed through the extension tube 5, one end of the rope body 6 is in the cavity 2 and wrapped around the driven end of the transmission component 4, and a circular hook 7 is formed between the other end of the rope body 6 and the end of the extension tube 5. The size of the circular hook can be adjusted to catch foreign objects of different sizes; the rear end of the handle portion 1 has a bendable hook portion 8.

[0020] The transmission assembly 4 includes a rotatable roller 9 arranged in the cavity 2 via a support frame, as shown in the attached Figure 2 As shown, a roller 9 is embedded in the roller groove 3, and transmission is achieved by turning the roller during use. The cavity 2 contains a wheel support frame 10, on which a rope collection shaft 11 is mounted. The rope 6 is wound around one end of the rope collection shaft 11. The rope collection shaft 11 is mounted with a transmission gear 12 that meshes with the roller 9. The roller and the transmission gear have helical teeth on their surfaces, and the two are arranged in an interlaced manner. The roller drives the transmission gear to rotate, thereby rotating the rope collection shaft. One end of the rope collection shaft 11 has a baffle 13 to prevent the rope 6 from slipping. The rope is wound around the rope collection shaft. Rotating the rope collection shaft in different directions can adjust the amount of rope wrapped around the rope collection shaft, thereby adjusting the size of the circular hook. The baffle prevents the rope from slipping. The front end of the handle portion 1, near the extension tube 5, has an illuminating lamp 14. When the circular hook is used to remove foreign objects, it can illuminate the interior of the nasal cavity, making it easier to see the location of the foreign object.

[0021] The hook portion 8 includes a hose body 15 disposed at the rear end of the handle portion 1. The hose body has a certain flexibility and can be bent. The end of the hose body 15 has a foreign body hook 16. A pull wire assembly 17 is installed in the hose body 15. Figure 3As shown, the pull-wire assembly 17 includes an adjustment knob 171 threadedly mounted on the outside of the rear end of the handle 1. The flexible tube 15 has a wire channel 172, and a wire 173 is passed through the wire channel 172. One end of the wire 173 is wrapped around the tail end of the adjustment knob 171, and the other end of the wire 173 is connected to the tail end ring of the foreign body hook 16. The end of the flexible tube is originally bent at a certain arc, and the wire channel is inside the curved arc. The adjustment knob is rotated, pulling the wire, tightening the wire, and driving the flexible tube to bend. The curvature of the flexible tube changes, allowing the foreign body hook to be located at different positions, smoothly removing foreign objects. The tail end of the adjustment knob 171 has an annular groove 174, and the wire 173 is wrapped around the annular groove 174. The wire can be within the annular groove to prevent it from slipping when the wire is retracted or released. The utility model has two different foreign body removal structures: a round hook and a curved hook. When used in combination, it can improve the efficiency of removing foreign objects in the nasal cavity.

[0022] The working principle of the utility model is as follows: the toggle end of the transmission component rotates back and forth, which can drive the output end of the transmission component to rotate in different directions. The output end of the transmission component is connected to the rope body to realize the retraction and release of the rope body. The rope body is in the extended thin tube. When the line is reeled in, the size of the circular hook gradually becomes smaller, and when the line is released, the size of the circular hook gradually increases. The size of the circular hook can be flexibly adjusted to facilitate the flexible trapping of foreign objects and their removal.
