DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 5 As shown:

[0038] Embodiment 1: The present invention provides a digestive tract foreign body extractor, comprising an outer sleeve assembly 11, wherein a control rod assembly 12 is disposed inside the outer sleeve assembly 11, wherein one end of the control rod assembly 12 is rotatably connected to a movable clamping block assembly 13, and one side of the movable clamping block assembly 13 is further connected to a traction rope 14;

[0039] The outer sleeve assembly 11 includes an outer sleeve body 111, an inner movable groove 112 is formed inside the outer sleeve body 111, and a receiving groove 113 is formed on one side of the outer sleeve body 111;

[0040] The control rod assembly 12 includes a control rod body 121 which is limitedly slidably embedded in the inner movable groove 112, one end of the control rod body 121 is fixedly connected to a connecting bracket 122, the end of the connecting bracket 122 is fixedly connected to a fixing clamp 123, and the outer side of the connecting bracket 122 is fixedly connected to a shaft rod 124;

[0041] The movable clamping block assembly 13 comprises a movable clamping block body 131, one end of the movable clamping block body 131 is fixedly connected to a second connecting bracket 132, and the middle of the second connecting bracket 132 is also fixedly connected to a connecting rod 133;

[0042] A torsion spring 134 is also sleeved on the outer side of the shaft 124;

[0043] The second connecting bracket 132 is rotatably embedded in the shaft 124, one end of the torsion spring 134 is embedded in the first connecting bracket 122, and the other end of the torsion spring 134 is embedded in the second connecting bracket 132, and the torsion spring 134 drives the movable clamping block body 131 to engage with the fixed clamp 123;

[0044] One end of the traction rope 14 passes through the outer sleeve body 111 and is connected to the connecting rod 133;

[0045] When in use, pushing the control rod body 121 can move the connecting bracket 122 and the fixing clamp 123, and the movement of the connecting bracket 122 will cause the movable clamping block assembly 13 to extend therewith;

[0046] When the fixed clamp 123 and the movable clamping block assembly 13 are close to the foreign object, the traction rope 14 is pulled to make the connecting rod 133 drive the second connecting bracket 132 to move around the shaft 124, so that the movable clamping block body 131 is rotated and opened, and the foreign object can be located between the fixed clamp 123 and the movable clamping block body 131 after pushing the extractor;

[0047] When the second connecting bracket 132 rotates, the torsion spring 134 will also be twisted. When the foreign object is located between the fixed clamp 123 and the movable clamping block body 131, the traction rope 14 is loosened, and the torsion spring 134 is reset to make the movable clamping block body 131 rotate and fix the foreign object on the fixed clamp 123.

[0048] Due to the presence of foreign matter, the movable clamping block body 131 cannot be completely embedded in the fixing clamp 123. After the foreign matter is initially fixed, pulling the operating rod body 121 can move the fixing clamp 123 and the movable clamping block body 131 and store them in the storage groove 113. At the same time, the movable clamping block body 131 can be further fixed by pressing against the edge of the storage groove 113.

[0049] Specifically, a reset groove 114 is further provided inside the outer sleeve body 111;

[0050] The outer side of the control rod body 121 is also fixedly connected to a limit ring 125, and a spring 126 is provided on one side of the limit ring 125;

[0051] The limiting ring 125 and the spring 126 are both located in the reset groove 114 , and the spring 126 drives the limiting ring 125 to move in a direction away from the receiving groove 113 .

[0052] Specifically, one end of the control rod body 121 away from the connecting bracket 122 is also fixedly connected with a push ring 127 .

[0053] As can be seen from the above, the push ring 127 can facilitate the movement of the control rod body 121. When the control rod body 121 moves, the limit ring 125 slides and the spring 126 is compressed in the reset groove 114, thereby providing a driving force for resetting the control rod body 121.

[0054] like Figure 3 and Figure 4 As shown:

[0055] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a sliding groove 115 is further provided on the outer side of the outer sleeve body 111;

[0056] A guide block 128 is also fixedly connected to the outer side of the control rod body 121;

[0057] The guide block 128 is limitedly slidably engaged in the sliding groove 115 .

[0058] Specifically, a positioning groove 116 is further provided on the outer sleeve body 111 at a position connected to the sliding groove 115;

[0059] The guide block 128 matches the positioning groove 116 .

[0060] Specifically, a handle 117 is fixedly connected to the outer side of the outer sleeve body 111 .

[0061] As can be seen from the above, when the control rod body 121 is pushed, the guide block 128 will move in the sliding groove 115, thereby making it easier for the staff to understand the position of the fixing clip 123;

[0062] At the same time, when the guide block 128 moves to the limit position, the guide block 128 can be transferred from the sliding groove 115 to the positioning groove 116 by rotating the control rod body 121, thereby achieving a fixing effect.

[0063] like Figure 5 and Figure 6 As shown:

[0064] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that a storage slot 129 is further provided on one side of the fixing clip 123 .

[0065] Specifically, one side of the movable clamping block body 131 is also fixedly connected with a limiting tooth 135;

[0066] The limiting teeth 135 block the storage slot 129 .

[0067] As can be seen from the above, the storage slot 129 can facilitate the storage of foreign objects, and the foreign objects can be clamped and fixed by the edge of the fixing clip 123; when the movable clamping block body 131 is close to the fixing clip 123, the storage slot 129 can be blocked by the limiting teeth 135, thereby preventing the foreign objects from falling.
