Claim Text:
1. A ureteral calculus suction instrument comprising: a shaft, through which a suction channel runs, said suction channel being connectable to a suction device; a collecting container with a distal opening and a proximal opening arranged distally from the shaft, of which the proximal opening is connected to a distal end of the suction channel and the distal opening is in fluid communication with the proximal opening through the collecting container such that suction from the suction device is provided at the distal end opening to suction one or more ureteral calculi into the collecting container via the distal opening; and a closing member comprising a thread having a first end and a looped portion at a second end, the looped portion being looped around the collecting container at a position proximal to the distal opening, wherein a diameter of the looped portion decreases to close the distal opening of the collecting container when the first end is pulled proximally by a user.
