  • Publication number: 20210085158
    Abstract: An endoscope includes an insertion portion including a first conduit for delivering a fluid, and a second conduit for suctioning a fluid. A distal end opening of the second conduit may have an opening area larger than an opening area of a distal end opening of the first conduit, and in the second conduit, an inside diameter on a distal end side may be smaller than an inside diameter on a proximal end side. In a calculus collecting method, fluid can be delivered into the subject from the first conduit, and fluid can be suctioned into the second conduit. Intermittently, fluid delivery from the first conduit may be stopped so that fluid can be delivered through the second conduit.
