Abstract:
Disclosed is an endoscope with an enlargeable tail end, comprising an insertion part (7) and an endoscope main body (1), wherein the insertion part (7) comprises a housing (4), a working tract (2), a camera (6) and an electric wire band (5), wherein the working tract (2), the camera (6) and the electric wire band (5) are all located in the housing (4); one end of the electric wire band (5) is connected to the camera (6), and the other end thereof passes through the housing (4) and is connected to the endoscope main body (1); the camera (6) is arranged at a tail end in the housing (4); the tail end of the housing (4) is provided with a notch (10); the working tract (2) or the camera (6) can extend out from or retract back into the notch (10); and when the working tract (2) or the camera (6) extends out of the notch (10), the working tract (2) and the camera (6) are in a parallel state. The endoscope with the enlargeable tail end can realize the enlarging and retracting of the tail end of the endoscope; the tail end of the endoscope is enlarged after passing through a narrow human body tract so that the working tract (2) or the camera (6) extends out and the working tract (2) or the camera (6) are in a parallel position so the inner diameter of the working tract (2) is significantly increased and more instruments can pass through same to take out larger foreign matter and obtain more ideal 3D images.
