[0021] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0022] like Figure 1-5 As shown, a throat foreign body remover comprises a hand-held part 1, an outer sleeve 2 is provided at the distal end of the hand-held part 1, a telescopic rod 3 is provided inside the outer sleeve 2, two naturally opened elastic clamps 31 are provided at the front end of the telescopic rod 3, the elastic clamps 31 are made of elastic metal, and can be spring steel, a control hole 11 is provided inside the hand-held part 1, an adjusting slider 4 is movably installed in the control hole 11, the adjusting slider 4 is connected to the telescopic rod 3, the adjusting slider 4 comprises an adjusting column 41, pulling bosses 42 are provided on both sides of the adjusting column 41, side slide grooves 13 are opened on both sides of the hand-held part 1, the pulling bosses 42 are movably installed through the side slide grooves 13, and a spring 43 is provided between the adjusting column 41 and the palm contact ring 14.

[0023] When the device is designed in this way, when in use, the device is not subjected to external force, and the elastic force of the spring 43 pushes the telescopic rod 3 to move forward in the outer sleeve 2. At this time, the elastic clamp block 31 partially protrudes from the distal end surface of the telescopic rod 3, and the two elastic clamp blocks 31 are in a naturally open state. The medical staff adjusts the position of the device. When the foreign matter to be removed is located between the two elastic clamp blocks 31, the finger pulls the adjustment slider 4 to move proximally by pulling the boss 42. At this time, the telescopic rod 3 is also forced to move proximally relative to the outer sleeve 2, and the elastic clamp block 31 gradually moves into the outer sleeve 2. At this time, the elastic clamp block 31 is closed by force to complete the clamping of the foreign matter. During operation, the device can be controlled to move forward to avoid the foreign matter being located at a position too front of the elastic clamp block 31, which causes the elastic clamp block 31 to close backward and fail to clamp. The overall result of the present disclosure is tubular, which can be operated more separately and avoid interference.

[0024] A spring mounting groove 44 is provided on the proximal end surface of the adjusting column 41, and one end of the spring 43 close to the adjusting column 41 is movably installed in the spring mounting groove 44. The purpose of such design is to ensure the stability of the installation of the spring 43. At the same time, a reinforcing section 12 is provided at the proximal end of the hand-held portion 1, and the diameter of the reinforcing section 12 is larger than that of the distal end of the hand-held portion 1. The side slide groove 13 is provided at the position of the reinforcing section 12, so that the reduction in the structural strength of the hand-held portion 1 caused by the opening of the side slide groove 13 can be avoided. A palm resistance ring 14 is provided at the proximal end of the control hole 11, and the palm resistance ring 14 is in the shape of a round cake, which is convenient for the resistance of the palm during operation.

[0025] The distal end of the outer sleeve 2 is provided with a rounded corner 25 , so as to ensure smooth movement of the elastic clamping block 31 .

[0026] In some disclosures, the adjusting column 41 and the telescopic rod 3 are integrally arranged, and the outer sleeve 2 and the hand-held part 1 are integrally arranged, so that production is convenient.

Through such a design, the insertion part entering the human body can be replaced to avoid cross infection. At the same time, the threaded connection method is convenient and fast.

[0028] In some disclosures, a positioning column 15 is provided on one side of the palm contact ring 14 close to the reinforcement section 12, and a positioning guide hole cooperating with the positioning column 15 is provided on the end face of the adjustment column 41 close to the palm contact ring 14, and the positioning column 15 is movably installed in the positioning guide hole, thereby increasing the stability of the movement of the adjustment column 41 and the stability of the installation of the spring 43.

[0029] In some embodiments, other settings are the same as above, with the difference being that the front end of the outer sleeve 2 is bent, and the outer sleeve 2 is composed of an outer straight segment 21, an outer curved segment 24, and a second outer straight segment 23 from the proximal end to the distal end. The outer sleeve 2 can be made of a stainless steel tube, and the telescopic rod 3 is composed of an inner straight segment 33, an inner curved segment 35, and a second inner straight segment 34 from the proximal end to the distal end. The elastic clamp block 31 is arranged on the end face of the second inner straight segment 34, and the material of the bending part of the telescopic rod 3 can be soft stainless steel wire. Furthermore, the elastic clamp block 31 can be welded or crimped to the distal end of the second inner straight segment 34.
