[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Through the arrangement of the loop wire and the clamping rod, when cleaning the patient's nasal cavity, the size of the loop wire can be controlled by sliding the sliding block, and the spacing of the clamping rods can be indirectly controlled by controlling the size of the loop wire. At this time, the doctor extends the loop wire into the patient's nasal cavity. When the loop wire contacts the foreign matter in the nasal cavity, the doctor can slide the sliding block to adjust the spacing of the clamping rods until the clamping rods can tightly clamp the foreign matter. Then the doctor can take the clamping rod out of the patient's nasal cavity. The advantage of such a design is that this utility model can efficiently take out some objects with surfaces that are difficult to grasp, or irregular shapes and easily broken objects (such as paper, etc.), which greatly improves the adaptability of the product. Secondly, the utility model has a simple structure, is easy to operate, and is very easy to operate.

[0015] 2. The angle between the loop wire and the fixed wire is forty-five degrees. Through such a design, when the object is difficult to remove, first slide the sliding block to shrink the loop wire to the minimum state, then extend it into the patient's nasal cavity, let the clamping rod pass over the foreign body in the nasal cavity, and then slide the sliding block again to adjust the size of the loop wire until it is the appropriate size. At this time, the loop wire will be stuck on the foreign body in the nasal cavity, and the doctor can pull the foreign body out of the patient's nasal cavity by pulling. The advantage of this design is that the foreign body in the nasal cavity can be more conveniently dragged out by pulling, the implementation effect is higher, and the operation is simpler.

[0021] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4 As shown, an instrument for removing foreign bodies from the nasal cavity comprises: a grip 1, the surface of which is roughened to increase friction and prevent the grip 1 from falling due to sweaty hands or sore arms from long-term hand-holding during operation.

[0023] One end of the gripping rod 1 is fixedly connected to a fixed wire 3, and the top end of the fixed wire 3 is fixedly connected to a ring-shaped wire 4, and the angle between the ring-shaped wire 4 and the fixed wire 3 is forty-five degrees. Through such a design, when the object is difficult to remove, first slide the sliding block 2 to shrink the ring-shaped wire 4 to the minimum state, and then extend it into the patient's nasal cavity, so that the clamping rod 41 passes over the foreign body in the nasal cavity, and then slide the sliding block 2 again to adjust the size of the ring-shaped wire 4 until it is a suitable size. At this time, the ring-shaped wire 4 will be stuck on the foreign body in the nasal cavity, and the doctor can pull the foreign body out of the patient's nasal cavity by pulling. The advantage of such a design is that the foreign body in the nasal cavity can be more conveniently dragged out by pulling, the implementation effect is higher, and the operation is simpler.

[0024] The size of the loop wire 4 can be changed according to the size of the foreign body in the patient's nasal cavity. A sliding wire 31 is provided on one side of the fixed wire 3. The sliding wire 31 can control the change of the size of the loop wire 4 by sliding. The two ends of the loop wire 4 are respectively fixedly connected to the fixed wire 3 and the sliding wire 31. The inner wall of the loop wire 4 is fixedly connected with four clamping rods 41. The clamping rods 41 can grab some objects that are difficult to grab on the surface, or have irregular shapes and are easy to break (such as paper, etc.). The included angle of the extension lines of the four clamping rods 41 is ninety degrees. A sliding groove 11 is provided on the side wall of the grip rod 1, and a slot 12 is provided at one end of the grip rod 1. The fixed wire 3 and the slot 12 are at the same end of the grip rod 1. The sliding block 2 is slidably connected to the inside of the sliding groove 11, and the sliding wire 31 is slidably connected to the inside of the slot 12. The sliding wire 31 penetrates the slot 12 and extends into the sliding groove 11. One end of the sliding wire 31 extending into the sliding groove 11 is fixedly connected to the sliding block 2.

[0025] Working principle: When cleaning the patient's nasal cavity, the size of the loop wire 4 can be controlled by sliding the sliding block 2, and by controlling the size of the loop wire 4, the spacing of the clamping rod 41 can be indirectly controlled. At this time, the doctor extends the loop wire 4 into the patient's nasal cavity. When the loop wire 4 contacts the foreign matter in the nasal cavity, the doctor can slide the sliding block 2 to adjust the spacing of the clamping rod 41 until the clamping rod 41 can tightly clamp the foreign matter, and then the doctor takes the clamping rod 41 out of the patient's nasal cavity. When encountering foreign matter that is difficult to remove, first slide the sliding block 2 to shrink the loop wire 4 to the minimum state, and then extend it into the patient's nasal cavity to allow the clamping rod 41 to pass over the foreign matter in the nasal cavity, and then slide the sliding block 2 again to adjust the size of the loop wire 4 until it is of a suitable size. At this time, the loop wire 4 will be stuck on the foreign matter in the nasal cavity, and the doctor can pull the foreign matter out of the patient's nasal cavity by pulling, and the work is completed.
