[0055] In this embodiment, when the second mounting rod 25 is retracted into the fixed tube 6 along with the injection tube 7, the snare 27 will also enter the fixed tube 6, causing the loop of the snare 27 to shrink. After the snare 27 cuts off the polyp tissue, the snare 27 can be extended or retracted according to the size of the polyp. After the snare 27 has encircled the polyp, the snare 27 can be shrunk to remove the polyp from the intestine.

[0056] The overall working principle of the present invention is as follows:

[0057] The device of the present invention is placed in the lumen of the endoscope, and when the endoscope is manipulated to reach the opening of a small organ, the device of the present invention is manipulated:

[0058] The device can be held and operated by setting a fixed component 1 and a movable handle 2. One hand holds the connecting ring 13, and the other hand drives the movable handle 2 to slide along the through groove 15, so that the cutter head at the lower end of the injection tube 7 can be moved by the main steel wire 19. At this time, the fixed tube 6 is telescoped along the sleeve 4, and the direction of the replacement cutter head can be fine-tuned by the set four-way fine-adjustment hook component 3. Specifically, the set main steel wire 19 is connected to the injection tube 7, and the corresponding auxiliary steel wire 18 can be driven to move by pulling the adjustment hook 17, thereby driving the corresponding hanging component 9 to move, so that the injection can be adjusted. The injection tube 7 can be fine-tuned, and then the replacement blade head can be fine-tuned. There can be fine-tuning in eight directions, which can be achieved by pulling a certain hook alone or pulling two adjacent hooks. The injection pressurizer 5 and the injection tube 7 can be used for pressurized injection. Specifically, the injection pressurizer 5 can pump liquid into the injection tube 7, and the liquid is then discharged through the injection hole through the flexible tube. The fill light 20 can be used for lighting. The replacement blade head can be used for hemostasis, electric shock or cutting operations. Specifically, the connecting frame 21 can be connected to the fixed tube 6, and the upper end of the telescopic rod 28 is connected to the injection tube 7 by a clamping arrangement. The hemostatic forceps 22 can be used to stop bleeding. Specifically, one hand holds the connecting ring 13, and the other hand drives the movable handle 2 to slide along the through groove 15, so that the telescopic rod 28 at the lower end of the injection tube 7 can be driven to move through the main steel wire 19. The telescopic rod 28 drives the connecting seat to rise, which can drive the angle between the connecting plates 29 to decrease, so that the hemostatic forceps 22 can be driven to close, and hemostasis can be performed by clamping. The first mounting rod 23 can be connected to the injection tube 7, and the electric shock operation can be performed through the electric shock head 24. One hand holds the connecting ring 13, and the other hand drives the movable handle 2 to slide along the through groove 15. The handle 2 slides along the through groove 15, so that the first mounting rod 23 at the lower end of the injection tube 7 can be driven to move through the main steel wire 19, so as to control the extension and retraction of the electric shock head 24. When the electric shock operation is not performed, the electric shock head 24 is in a retracted state. When the second mounting rod 25 shrinks into the fixed tube 6 along with the injection tube 7, the snare 27 provided will enter the fixed tube 6, so that the loop of the snare 27 shrinks. After the snare 27 cuts off the polyp tissue, the snare 27 can be expanded and contracted according to the size of the polyp. After the snare 27 covers the polyp, the snare 27 can be shrunk to remove the polyp from the intestine.
