As shown in fig. 1 to 5, the foreign body forceps for the department of gastroenterology comprises a handle holder 1, wherein the handle holder 1 comprises a handle part 11 and a sliding part 12 integrally formed with the handle part 11. The side wall of the handle portion 11 has a curved surface corresponding to a human hand, and the human hand is held by the handle portion 11 to grip the grip holder 1.

The grip assembly 3 is slidably connected to the handle base 1, and specifically, the grip assembly 3 includes a driving rod 34 slidably connected to the handle base 1, and the driving rod 34 is slidably connected to the sliding portion 12.

The left and right ends of the driving rod 34 all penetrate through the handle base 1, the left end portion of the driving rod 34 is connected with a clamping head, and the clamping head comprises an upper clamping plate 31 and a lower clamping plate 32 matched with the upper clamping plate 31. The clamp head further comprises a connecting column 33, the right end of the connecting column 33 is fixedly connected with a driving rod 34, and the left end of the connecting column 33 is obliquely and upwards fixedly connected with an elastic metal sheet 331. The elastic metal sheet 331 is made of a metal material with excellent elastic performance, and the elastic metal sheet 331 can be reset after being bent.

The elastic metal sheet 331 is fixedly connected with the upper nipper 31, and the upper nipper 31 is obliquely arranged upwards; the left end of the connecting column 33 is obliquely downwards fixedly connected with a connecting end plate 332, and the connecting end plate 332 is fixedly connected with the lower nipper plate 32; the lower nipper 32 is in a horizontal state.

Meanwhile, the upper end of the left side wall of the handle seat 1 is fixedly connected with an extrusion table 2 corresponding to the upper nipper 31, when the head of the clamp moves rightwards, the bottom of the extrusion table 2 can extrude the upper nipper 31, and the upper nipper 31 is clamped to the lower nipper 32 through the extrusion of the extrusion table 2. In order to increase the squeezing effect, according to the existing mode, the left end of the squeezing table 2 is provided with a downwards-arranged squeezing bulge 21, the bottom of the squeezing bulge 21 is provided with a squeezing bulge, and the squeezing force of the upper nipper 31 towards the lower nipper 32 is increased through the squeezing action of the squeezing bulge and the upper nipper 31.

Specifically, the driving rod 34 carries the gripper head to move to the right under the driving of the driving rod 34, and during the rightward movement of the driving rod 34, the upper nipper 31 inclined upward is pressed by the pressing table 2, and the upper nipper 31 moves downward to be nipped on the lower nipper 32.

In the actual working process, in order to increase the stability of the upper nipper 31 clamping the lower nipper 32, a plurality of nipper teeth a are respectively arranged at the bottom of the upper nipper 31 and the top of the lower nipper 32.

In order to pull the driving lever 34, a pulling member 35 is fixedly connected to a right end of the driving lever 34, and the driving lever 34 is pulled to slide by the pulling member 35. The specific structure of the pulling member 35 is as follows:

the pulling member 35 includes an end plate 351 fixedly coupled to the right end portion of the driving rod 34, and upper and lower ends of the end plate 351 are slidably coupled to the sliding portion 12 through guides 354. Guide 354 includes a guide rod 3541 fixedly attached to the left side of end plate 351; the left end of guide rod 3541 extends into sliding part 12 (sliding part 12 is provided with a rod cavity adapted to guide rod 3541), and guide rod 3541 is slidably connected to sliding part 12. A spring 3542 is sleeved on the guide rod 3541, and the left end part of the spring 3542 is fixedly connected to the right side wall of the sliding part 12; the right end of the spring 3542 is fixedly attached to the left side wall of the end plate 351. A pulling rod 352 is fixedly connected to the right side wall of the end plate 351, and a tapered handle 353 is fixedly connected to the pulling rod 352.

When a user needs to hold a foreign object during a surgical operation, the user drives the end plate 351 to the right, and at this time, the end plate 351 drives the guide rod 3541 to slide to the right, and the spring 3542 is extended. In the process, the driving rod 34 moves towards the right, the driving rod 34 carries the clamp head to move towards the right, in the process that the driving rod 34 moves towards the right, the upper clamp plate 31 inclined upwards is pressed by the pressing table 2, the upper clamp plate 31 moves downwards to clamp the lower clamp plate 32, and then the foreign matter to be clamped is clamped. When the pulling force is released, the driving rod 34 moves to the left by the elastic restoring force of the spring 3542, and at this time, the upper nipper 31 is pressed by the pressing table 2, and since the upper nipper 31 is connected by the elastic metal piece 331, the upper nipper 31 is tilted upward and restored by the elastic restoring force of the elastic metal piece 331, and at this time, the upper nipper 31 releases the foreign matter.

By adopting the device components, an operator can clamp foreign matters only by pulling and loosening the conical handle 353. The pliers with the structure avoid the problem that the operation is inconvenient for the process in a narrow digestive tract because the pliers need to be opened in the process of opening or closing the pliers in the traditional pliers. The operator holds the handle base 1 by hand, extends the clamp head into the alimentary canal, and pulls the taper handle 353 to complete the process.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
