It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0022] like Figures 1 to 4 The foreign body clamping device for gastroenterology comprises a centrally controlled shell 1, a protective device 2 and a clamping assembly 3, wherein the side wall of the shell 1 is provided with a limiting hole 11, and the bottom of the shell 1 is also provided with a base 12, the base 12 is cup-shaped, sleeved on the outer side wall of the bottom of the shell 1, and the base 12 can rotate around the outer side of the bottom side wall of the shell 1. The rotating rod 5 passes through the top of the shell 1 and the center of the base 12, and a movable plate 4 is provided inside the shell 1, and two opposite limiting blocks 41 are provided on the movable plate 4, and the contact surface between the side of the movable plate 4 close to the inner wall of the shell 1 and the inner wall of the shell 1 is smooth, the rotating rod 5 passes through the center of the movable plate 4 and the movable plate is fixed on the rotating rod 5, and the end of the rotating rod 5 located on the top side of the shell 1 is also fixedly installed with a push handle 51, and a spring 7 sleeved on the surface of the rotating rod 5 is provided between the movable plate 4 and the bottom of the shell.

[0023] In this embodiment, a protective device 2 and a clamping assembly 3 are provided on one end of the rotating rod 5 located on one side of the bottom of the shell 1. The protective device 2 includes a protective cover 21, and the protective cover 21 is composed of two hemispherical structures, which are spherical structures formed by mutual cooperation. A bracket 23 is fixedly provided on the side of the protective cover 21 close to the rotating rod 5, and the end of the bracket 23 away from the protective cover 21 is movably connected to the side wall of the rotating rod 5 through a fixed shaft 231. Connecting blocks 22 are fixed at the center positions of the left and right sides of the outer wall 21 of the protective cover. The connecting block 22 is movably connected to the telescopic rod 14 through a fixed shaft 8, and the end of the telescopic rod 14 away from the connecting block 22 is movably connected to the edge of the base 12 through a fixed shaft 8.

[0024] In this embodiment, a movable push rod 6 is provided at the inner center of the rotating rod 5, a push handle 2 61 is provided at the first end of the push rod 6, a groove is provided inside the end of the rotating rod 5 located on one side of the base 12, a fixing plate 62 is provided at the second end of the push rod 6 located in the groove, a clamping assembly 3 is provided on the fixing plate 62, and the clamping device 3 includes two connecting rods 31, the two connecting rods 31 are respectively mounted on both sides of the fixing block 62, the connection between the two connecting rods 31 and the fixing block 62 is rotatably connected by a pin, the side wall of the rotating rod 31 on the opposite side away from the end of the fixing block 62 is bonded with medical rubber, the rubber pad has a large friction, and can prevent the clamped foreign body from slipping during the removal process, the side wall on the opposite side of the connecting rod 31 and the center of the fixing block 62 are connected with a spring 1 32, which is used to adjust the position of the two connecting rods 31. The size of the fixing block 62 is smaller than the size of the groove opening of the rotating rod 5, so that the fixing block 62 can smoothly enter and exit the groove.

[0025] In this embodiment, the shell 1 is made of medical PVC material.

[0026] In this embodiment, the protection device 2 and the clamping assembly 31 are made of stainless steel and have smooth edges and corners. The smooth edges and corners prevent the edges from damaging the patient's mucosa during the removal of foreign objects.

[0027] In this embodiment, when in use, firstly, the position where the foreign body is stuck is analyzed according to the medical image of the patient, the approximate length is estimated, and the push handle 1 51 is pushed to drive the rotating rod 5 to move forward, so that the protective cover 21 fixed on the rotating rod 5 is squeezed and opened, revealing the clamping component 3 covered therein, and the push handle 1 51 is rotated to drive the movable plate 4 to rotate, so that the limiting block 41 on the movable plate 4 is stuck in the limiting hole 11 of the shell 1, so that the protective cover 21 is always in the open state, and then the push handle 2 61 is pushed to drive the fixed block 62 to move forward, and the spring 1 32 makes When the connecting rod 31 is opened and moved to the appropriate position, the push handle 61 is pulled backward. Due to the size of the groove opening of the rotating rod 5, the connecting rod 31 clamps the foreign object. Because the side wall of the connecting rod 31 on the opposite side of the end away from the fixed block 62 is bonded with a medical rubber pad, the friction force is increased, so that the foreign object will not fall easily. At this time, the movable plate 4 is rotated to make the limit block 41 leave the limit hole, and the rotating rod 5 is pulled backward to close the protective cover 21, covering the clamping assembly 3 and the foreign object inside, and the foreign object is completely removed to avoid secondary injury caused by the foreign object falling.

[0028] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
