ABSTRACT:
An apparatus for removing a foreign matter from the human body cavity includes a sheath to be inserted into the body cavity, a foreign matter trapping section and a device for selecting the flexing length of the flexing portion of the sheath. The sheath is made of a flexible material, and the foreign matter trapping section comprises a ring member disposed at the front end of the sheath and trapping wires extending through the lateral side wall of the sheath with their corresponding ends connected to the ring member in circumferentially spaced relation and their other ends individually movable longitudinally of the sheath. By individually operating the trapping wires a foreign matter within the body cavity can be positively caught by or held within a cage defined by the trapping wires. The flexing length selection device can properly adjust the flexing length of the flexing portion of the sheath to be inserted into the body cavity.
