摘要：
FIELD: medicine.SUBSTANCE: version of the device for foreign objects manipulation with in hollow bodies, comprising a catheter, a guide and an object trap with a mesh surface, which is connected to the catheter and/or conductor, and the conductor is hollow or solid, the object trap is provided with a mesh surface, at least in one part of the trap. The object trap preferably includes additional loops stacked with intersection and/or interlacing with each other to form a mesh surface, at least in one part of the trap. Object trap, catheter and guide are made from metal material such as nitinol, stainless steel, radiopaque alloy non-metallic material, such as polyamide, caprone, nylon composite material such as metal and nonmetal materials. The catheter may be designed with double walls, which are movable relative to each other. The conductor may comprise two wires, with a trap located between distal ends, and the wires are movable relative to each other. Also a version of the device for foreign objects manipulation in hollow bodies is proposed, comprising a catheter, a guide and an object trap with a mesh surface, at that, the object trap, the catheter and the guide are made from one original piece, for example a catheter, a wire, a tape, and the guide is hollow or solid, while the object trap is provided with a mesh surface, and the possibility of its placement, at least in one part of the trap.EFFECT: device allows effective manipulation of foreign objects in the hollow organs of a living organism due to improved extraction properties of the foreign object trap and its extended functionality.17 cl, 11 dwgИзобретение относится медицинским инструментам для эндоскопической хирургии и может быть использовано для извлечения инородных тел из полых и трубчатых органов, например мочевых, желчных камней, тромбов, полипов, и для других манипуляций с инородными объектами. Предложенное устройство позволяет эффективно проводить манипуляции с инородными объектами в полых органах
