The utility model discloses a double suction tube type
enteroscope, which comprises an operating rod, a probe
assembly, a suction tube and a small
air pump, the end part of the operating rod is provided with an
insertion tube, the probe
assembly comprises a camera, the outside of the camera is provided with a first mounting block, and the front surface of the first mounting block is provided with a suction tube opening; and a communicating piece is arranged between the suction
pipe and the small suction pump. By means of the design of the
intubation tube, the probe
assembly, the suction tube and the small suction pump, the
biopsy device extends into the
small intestine through the
biopsy tube and the
biopsy opening to conduct polyp excision, at the moment, the
biopsy device can be pulled to the front face of the first installation block, the position of the polyp is observed through the camera, and the operation is convenient. The small
air pump corresponding to the position of the suction
pipe opening is started, air in the suction
pipe is extracted through the small
air pump, negative pressure is generated in the suction pipe, and therefore the polyp is firmly adsorbed to the front face of the suction pipe opening and cannot fall off at will.
