[0002] Foreign body forceps are an expensive tool that is usually used in conjunction with an endoscope to clamp and remove foreign bodies from the human digestive tract. The forceps head is usually made of stainless steel and has a variety of head designs suitable for grabbing various foreign bodies.
[0003] In the prior art, foreign bodies stuck in the human digestive tract are generally located laterally on the inner side of the digestive tract. After the existing foreign body forceps are inserted into the digestive tract and clamp the foreign body, a pulling force is applied to the foreign body so that the foreign body can be removed from the digestive tract. However, during the removal process, both sides of the foreign body are still in contact with the inner wall of the digestive tract. During the movement, the foreign body is easily affected by the pulling force, resulting in secondary scratches on the digestive tract, causing the digestive tract to be broken and bleeding.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a foreign body forceps for gastroenterology, comprising a hollow bar 1, a clamping mechanism 2 is provided on the hollow bar 1, an expansion protection mechanism 3 is provided on the hollow bar 1 and the clamping mechanism 2, the clamping mechanism 2 comprises a hollow plate 21, the hollow plate 21 is fixedly connected to the left end of the hollow bar 1, the expansion protection mechanism 3 comprises a hollow block 31, the hollow block 31 is fixedly installed at the center of the top of the hollow plate 21, the front and back sides of the hollow block 31 are fixedly connected to a hollow cylinder 32, a sealing slider 321 is slidably connected to the inner wall of the hollow cylinder 32, the sealing slider 321 is fixedly connected to an extension square rod 322 on one side away from the hollow block 31, and the extension square rod 322 extends to the outside of the hollow cylinder 32 at one end away from the sealing slider 321 and is fixedly connected to an arc-shaped expansion The expansion plate 33 and the right side of the hollow block 31 are fixedly connected with an trachea 34, and the end of the trachea 34 away from the hollow block 31 is fixedly connected with an elastic airbag 35. The elastic airbag 35 is an existing structure. The elastic airbag 35 is manually squeezed, and the elastic airbag 35 can produce compressed elastic deformation. The gas in the inner cavity of the elastic airbag 35 can be transported to the inner cavity of the hollow block 31 through the trachea 34, and the gas then enters the interior of the hollow cylinder 32. The air pressure pushes the sealing slider 321 to slide in the inner cavity of the hollow cylinder 32, so that the arc expansion plate 33 is expanded. The contact surface between the arc expansion plate 33 and the inner wall of the digestive tract is arc-shaped. In the process of extracting the arc expansion plate 33, the digestive tract can be further opened, which can maximize the guarantee that there will be no impact on the digestive tract and increase safety.
[0024] As an implementation method in this embodiment, Figure 1-Figure 5As shown, a hoop is fixedly sleeved on the outer wall of the air pipe 34, and the hoop is fixedly installed on the top of the hollow bar 1. A fixed block 22 is fixedly installed on the bottom of the inner wall of the hollow plate 21. A rotating kit 23 is rotatably connected to the outer wall of the fixed block 22. A clamp head 24 is fixedly installed on the left side of the rotating kit 23. A groove 25 is provided on the outer surface of the clamp head 24. A half-tooth ring 26 is fixedly installed on the outer wall of the fixed block 22. A telescopic bar 28 is slidably connected to the inner wall of the hollow plate 21. The left end of the telescopic bar 28 extends into the inner cavity of the hollow plate 21 and is fixedly connected to a rack 27. The outer surface of the rack 27 is meshed with the outer surface of the half-tooth ring 26. The right end of the telescopic bar 28 extends to the right side of the hollow bar 1. The clamping mechanism 2 also includes an alloy part 29, which is fixedly installed in the hollow On the outer wall of the bar 1, a threaded rod 291 is threadedly connected to the inner wall of the alloy part 29. The left end of the threaded rod 291 is rotatably connected to the right end of the telescopic bar 28. A handle 292 is welded on the outer wall of the alloy part 29. Manually rotating the threaded rod 291 can make the threaded rod 291 move to the left as a whole, thereby pushing the telescopic bar 28 to move to the left, and synchronously driving the rack 27 to move to the left. Due to the meshing design between the semi-toothed ring 26 and the rack 27, the rotating kit 23 can be rotated on the outer wall of the fixed block 22, so that the clamp head 24 is opened, and then the end of the clamp head 24 is moved to the vicinity of the foreign object, and then the threaded rod 291 is rotated in the opposite direction to reset the clamp head 24, thereby realizing the function of clamping the foreign object. The design of the groove 25 improves the stability of the clamping.
[0025] Working principle: Move the clamp head 24 to the vicinity of the foreign object, and then manually rotate the threaded rod 291 to make the threaded rod 291 move to the left, and the rack 27 is driven to move to the left by the transmission of the telescopic rod 28, so that the rotating kit 23 rotates on the outer wall of the fixed block 22, prompting the clamp head 24 to open, and then move the end of the clamp head 24 to the foreign object, and then rotate the threaded rod 291 in the opposite direction to reset the clamp head 24 and realize the function of clamping the foreign object. Before pulling out the clamp head 24, the gas in the inner cavity of the elastic airbag 35 is transported to the inner cavity of the hollow block 31 through the trachea 34, and the gas then enters the interior of the hollow cylinder 32. The air pressure pushes the sealing slider 321 to slide in the inner cavity of the hollow cylinder 32, so that the arc expansion plate 33 is unfolded, and the clamp head 24 can be safely pulled out.
[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
