DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0018] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a double-headed circular ring-type nasal foreign body removal device provided by the utility model;

[0019] Figure 2 This is a schematic diagram of the connection between the first round rod and the second round rod of the utility model; Figure 3 For this utility model Figure 2 The enlarged schematic diagram at A in the middle; Figure 4 A double-headed circular ring-type nasal foreign body removal instrument, comprising a grip rod 1, the surface of which is a rough structure, which increases the resistance during operation and prevents the instrument from being unstable when the operator exerts force. Two removal rings 2 are arranged on the outside of the grip rod 1. The two removal rings are hollow elliptical rings. When the instrument is extended to the back of the foreign body, it is easy to fix the foreign body in the ring. The two removal rings 2 are of different sizes. According to the different ages of the patients and the different sizes of the nasal cavities, the appropriate end can be selected for operation. A protrusion 3 is connected to the outer wall of one side of the removal ring 2. The grip rod 1 and the protrusion 3 are connected by an arc rod 4. A replacement mechanism for the removal ring 2 is arranged inside the protrusion 3.

[0020] Reference Figure 1 and Figure 4The replacement mechanism includes a T-shaped block 301, which is arranged inside the groove 302 opened by the protrusion 3, and the arc rod 4 extends to the outer wall of one side of the groove 302 and is connected to one end of the T-shaped block 301. The outer surface of the T-shaped block 301 is connected with two vertical rods 303 which are symmetrically distributed up and down, and a movable groove 304 is opened inside the vertical rod 303. The bottom wall of the movable groove 304 is connected to a first spring 305, and the top of the first spring 305 is connected to a first extrusion plate 306. The top of the first extrusion plate 306 is connected to a connecting rod 307, and the connecting rod 307 extends out of the top of the vertical rod 303 and is connected to a pressing plate 308. The T-shaped block 301 has a limiting hole 309 opened on the top wall of the groove 302, and the inner wall of the limiting hole 309 is connected to the outer wall of the pressing plate 308.

[0021] Through the above technical solution, when the deformed removal ring 2 needs to be replaced, the pressing plate 308 in the limiting hole 309 is pressed, so that the pressing plate 308 drives the connecting rod 307 to move downward to the inside of the groove 302, and then pulls the removal ring 2 to move, so that the protrusion 3 is separated from the arc rod 4, and then the deformed removal ring 2 can be replaced, and the installation time is short, avoiding affecting the use efficiency of the removal ring 2.

[0022] Reference Figure 2 The gripping rod 1 includes a first round rod 101 and a second round rod 102. A telescopic groove 103 is provided inside the first round rod 101. A telescopic rod 104 is provided inside the telescopic groove 103. One end of the telescopic rod 104 extends out of the first round rod 101 and is connected to an outer wall of one side of the second round rod 102. The second round rod 102 can be pulled to move away from the first round rod 101 through the telescopic rod 104 in the telescopic groove 103, so that the use length of the gripping rod 1 can be adjusted so that the length can be adjusted according to the depth of the foreign body in the nasal cavity.

[0023] Reference Figure 2 and Figure 3 A hole slot 105 is provided inside the telescopic rod 104, a second spring 106 is provided inside the hole slot 105, a second extrusion plate 107 is connected to one end of the second spring 106 inside the hole slot 105, a fixing rod 108 is connected to the outer wall of the second extrusion plate 107 away from the second spring 106, a baffle 109 is provided inside the hole slot 105 and on the outer surface of the fixing rod 108, the outer wall of the baffle 109 is connected to the inner wall of the hole slot 105, and the fixing rod 108 extends out of the outer wall of the hole slot 105 and is connected to the inner wall of the fixing hole 110 provided inside the first round rod 101.

[0024] Through the above technical solution, after the telescopic rod 104 is adjusted in the telescopic slot 103, the fixing rod 108 in the hole slot 105 is moved to the inside of the fixing hole 110 opened in the first round rod 101 by the elastic action of the second spring 106. The telescopic rod 104 can be fixed by the cooperation between the fixing rod 108 and the fixing hole 110 to prevent the telescopic rod 104 from being reset, thereby making the adjusted first round rod 101 and the second round rod 102 more firm and reliable when used.
