DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Please see the attached Figure 1-2 This embodiment provides a nasal foreign body removal device, comprising a handle 1 connected to one end of a connecting rod 2, the other end of which is connected to a support strip 23. Preferably, the handle 1 and connecting rod 2 are detachably connected, allowing interchangeable attachment of different types of removal tips. The detachable connection may be threaded or magnetic. The support strip 23 includes a straight section 231 and an inclined section 232 connected to each other. The tip of the inclined section 232 is proximal to the axis of the connecting rod 2, while the tip of the inclined section 232 is distal to the axis of the connecting rod 2.

[0023] In this embodiment, the connecting rod 2 is provided with a side hole 21 and a through hole 22; wherein the side hole 21 is provided on the side wall of the connecting rod 2, and the axis of the through hole 22 coincides with the axis of the connecting rod 2;

[0024] It should be noted that a deformable ring 4 is provided at the end of the support strip 23. A stretching ring 5 is inserted into the interior of the deformable ring 4. The stretching ring 5 is connected to one end of the traction wire 3. After passing through the stretching ring 5, the traction wire 3 passes through the through hole 22 and the side hole 21 in sequence. After passing through the side hole 21, the other end of the traction wire 3 is connected to the traction ring 6. In an optional embodiment, the traction wire 3 is a steel wire.

[0025] Specifically, the deformable ring 4 includes a first elastic arc segment 42, a non-deformable arc segment 41 and a second elastic arc segment 43 connected in sequence; the non-deformable arc segment 41 is fixedly mounted on the end of the inclined plate segment 232; the first elastic arc segment 42 and the second elastic arc segment 43 are symmetrically arranged on both sides of the non-deformable arc segment 41. A circular hole is provided in the middle of the non-deformable arc segment 41, and the traction wire 3 passes through the non-deformable arc segment 41 through the circular hole. When in use, the traction wire 3 can pull part of the stretch ring 5 out of the circular hole. It is worth mentioning that the first elastic arc segment 42 and the second elastic arc segment 43 are made of rubber, and a thin metal wire for reinforcing rigidity is passed through the rubber material, so that the first elastic arc segment 42 and the second elastic arc segment 43 can be deformed and have a certain strength.

[0026] During use, before the nostril is inserted, the stretching ring 5 is not pulled and the deformable ring 4 is not deformed. If the patient's nostril is too small, the stretching ring 5 can be pulled to deform the deformable ring 4 so as to insert the nostril. After inserting the nostril, the deformable ring 4 directly passes over the foreign object or bypasses the foreign object from one side. After aiming at the foreign object, the stretching ring 5 is pulled to deform and close the deformable ring 4 until the foreign object can be taken out. The foreign object is taken out after it overlaps the deformed deformable ring 4.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
