[0022] The medical staff can select a clamping head 1 of a suitable shape according to the shape and volume of the foreign body, and then insert the clamping head 1 into the connecting part 2; the length of the clamping end of the clamping head 1 extending from the connecting part 2 can be adjusted according to the location of the foreign body; when it is necessary to clamp a foreign body in the throat, the length of the clamping head 1 extending from the connecting part 2 can be longer; when it is necessary to clamp a foreign body in the ear canal or nasal canal, the length of the clamping head 1 extending from the connecting part 2 can be slightly shorter; then the medical staff will put the connecting part 2 with the clamping head 1 installed on the fixing part 3; the connecting part 2 is in When inserted into the fixing part 3, the angle of the clamping head 1 will be automatically adjusted with the insertion depth of the connecting plate 2; the deeper the connecting part 2 is inserted into the fixing part 3, the smaller the angle of the clamping head 1; medical staff can adjust the length of the connecting part 2 inserted into the fixing part 3 according to the location, shape, and volume of the foreign matter, thereby adjusting the angle of the clamping head 1. The clamping head 1 can be inserted into the ear canal, nasal canal, or throat more smoothly, and at the same time, the occurrence of the clamping head 1 easily touching the patient's skin due to the excessive angle of the clamping head 1 can be greatly reduced.
[0023] Specifically, Figure 2-Figure 4As shown, the clamping head 1 includes a slide 4, on the inner side of which two symmetrically arranged clamping rods 5 are rotatably installed, and the clamping end of the clamping rod 5 extends to the outside of the slide 4; the slide 4 is elastically and slidably installed with two symmetrically arranged pressure rods 6 in the vertical direction, and the two pressure rods 6 are movably connected to the two clamping rods 5 respectively, and when the two pressure rods 6 move relative to each other, they can drive the two pressure rods 6 to perform clamping work; the connecting part 2 includes a connecting tube 7, the slide 4 is slidably connected to the connecting tube 7 in the horizontal direction, and the connecting tube 7 is slidably connected to two symmetrically arranged pressure plates 8 in the vertical direction; the two pressure plates 8 are respectively located on the sides of the two pressure rods 6 and are used to drive the pressure rods 6 to move; the pressure plates 8 are fixedly connected to the first traction rope 9, and the first traction rope 9 passes through the side wall of the connecting tube 7 away from the pressure plate 8 and is fixedly connected to the first slide plate 10, and the first slide plate 10 is slidably connected to the connecting tube 7 in the axial direction; the first slide plate 10 is fixedly connected to the second traction rope 9. The guide rope 11, the second traction rope 11 is away from the first slide plate 10, one end passes through the connecting tube 7 and extends to the outside of the connecting tube 7, and is fixedly connected to the first slider 12, and the first slider 12 is slidably connected to the connecting tube 7; a clamping column 13 is fixedly connected to the outer wall of the connecting tube 7, and the fixing part 3 includes a fixing tube 14, and a plurality of first clamping grooves 15 are provided on the fixing tube 14, and an extrusion spring 16 is installed in the fixing tube 14; the connecting tube 7 can be sleeved with the fixing tube 14, and the connecting tube 7 can make the clamping column 13 engage with the first clamping groove 15 under the action of rotation and the extrusion spring 16; a second slide plate 17 is elastically and slidably installed in the fixing tube 14, and a slot 18 is provided on the second slide plate 17, and a connecting column 19 is fixedly connected to the first slide plate 10, and a plurality of equidistantly distributed plug rods 20 are fixedly installed on the connecting column 19, and the plug rods 20 are clearance-matched with the slots 18, and a driving mechanism for driving the second slide plate 17 to move is provided on the side of the fixing tube 14.
[0024] When the clamping head 1 is connected to the connecting part 2, the medical staff only needs to insert the slide 4 into the notch provided in the connecting tube 7, and then fix the slide 4; when the connecting part 2 is connected to the fixing part 3, the medical staff aligns the clamping column 13 with the first clamping groove 15 provided on the fixing tube 14, and then inserts the connecting tube 7 into the fixing tube 14; when the clamping column 13 moves to the side of the first clamping groove 15, the medical staff can rotate the connecting tube 7, and the clamping column 13 will be clamped into the first clamping groove 15 under the elastic force of the extrusion spring 16; it should be noted that, if Figure 3 As shown, the plurality of first card slots 15 on the fixed cylinder 14 are arranged in a left-right distribution, which can reduce the distance between two adjacent first card slots 15, so that the angle adjustment of the clamping head 1 can be more precise; the medical staff can determine which first card slot 15 the clamping column 13 is to be clamped with according to the location, size and shape of the foreign matter; the longer the length of the clamping column 13 extending into the fixed cylinder 14, the smaller the angle of the clamping head 1; the specific working principle is as follows, in Figure 2When the clamping column 13 is in the state, the clamping column 13 is located on the side of the first first clamping groove 15 from the left. At this time, when the medical staff rotates the connecting tube 7 to make the clamping column 13 engage with the first clamping groove 15, the angle between the two clamping rods 15 is the largest; when the angle between the two clamping rods 15 needs to be reduced, the medical staff only needs to continue to push the connecting tube 7 into the fixed tube 14. At this time, the left end of the fixed tube 14 will drive the first sliding block 12 to move left relative to the connecting tube 7, and the first sliding block 12 will drive one end of the second traction rope 11 to move synchronously, and the other end of the second traction rope 11 will drive the first sliding block 10 to move right in the connecting tube 7, and the first sliding block 10 will drive the two pressing plates 8 to move relative to each other through the first traction rope 9. When the two pressing plates 8 move synchronously, they will drive the two pressing rods 6 to move toward the side close to the clamping rod 5, and the pressing rod 6 will drive the clamping rod 5 to rotate, and the angle between the two clamping rods 5 will be reduced; Figure 2 and Figure 4 As shown, when the connecting tube 7 and the fixed tube 14 are assembled, the connecting column 19 will also be inserted into the through hole provided on the second slide plate 17; when the clamping column 13 is located on the side of the first clamping groove 15, the insertion rod 20 just passes through the slot 18 and is located on the right side of the slot 18, and then when the connecting tube 7 rotates, it will drive the connecting column 19 and the insertion rod 20 to rotate synchronously, and the insertion rod 20 will rotate to a position staggered with the slot 18; when the medical staff subsequently manipulates the driving mechanism to control the second slide plate 17 to move to the right, the second slide plate 17 can drive the connecting column 19 and the first slide plate 10 to move synchronously through the insertion rod 20, and the first slide plate 10 can drive the pressing plate 8 to move toward the side close to the pressing rod 6 through the first traction rope 9, and the pressing rod 6 will drive the clamping rod 5 to rotate to perform the clamping work; through the arrangement of the clamping column 13 and the first clamping groove 15, the present invention has low difficulty and high speed in docking the connecting tube 7 and the fixed tube 14.
[0025] Specifically, Figure 1 and Figure 2 As shown, the driving mechanism includes a handle 21 , in which a pressure block 22 is slidably installed, and the pressure block 22 is connected to the second slide plate 17 via a third traction rope 23 .
[0026] After the medical staff inserts the clamp rod 5 into the ear canal, nasal canal or throat to approach the foreign body, they can press the pressing block 22, and the pressing block 22 can drive the second slide plate 17 to move forward through the third traction rope 23. Figure 2 The right side is moved as shown, so that the clamp rod 5 clamps the foreign body. When the medical staff presses the pressure block 22 again, the force is applied to the right side (i.e., to the outside of the ear canal, nasal canal or throat), which can greatly reduce the possibility of the clamp rod 5 poking the patient's skin.
[0027] Specifically, Figure 1 and Figure 5As shown, a second slider 24 is fixedly connected to the side wall of the slide seat 4; the second slider 24 is slidably connected to a clamping block 25 in the vertical direction; a plurality of second clamping grooves 26 equidistantly distributed are provided on the connecting tube 7; the clamping block 25 can be clamped with the second clamping groove 26; the second slider 24 is elastically slidably connected in the horizontal direction with a wedge-shaped push rod 27 for driving the clamping block 25 to fall off from the second clamping groove 26.
[0028] When adjusting the length of the working end of the clamping rod 5, the medical staff can press the wedge-shaped push rod 27 toward the inside of the second slider 24, and the wedge-shaped push rod 27 will drive the block 25 to move upward, and the block 25 will disengage from the second slot 26 on the connecting tube 7. Then the medical staff can push the second slider 24 and the slide 4 to slide in the connecting tube 7, adjust the position of the slide 4, and thus adjust the length of the clamping rod 5 extending out of the connecting tube 7; after the slide 4 moves to the appropriate position, the medical staff can release the wedge-shaped push rod 27, and the wedge-shaped push rod 27 will move back to the initial position under the elastic force of the spring, and then the block 25 will be inserted into the second slot 26 under the action of gravity; then the slide 4 and the connecting tube 7 can remain relatively fixed.
