【摘要】The utility model belongs to the field of medical devices, a cholangioscope gets balloon dilation catheter for stone is related to. This dilating vessel comprises pipe portion, sacculus portion, cone point portion, hydrophilic coating, development mark, wire guide pipe, notes liquid pipe, side opening, the sufficient chamber of sacculus, manometer, control valve, notes liquid mouth, seal wire entry. This balloon dilation catheter diameter is thin, can conveniently get into the choledochus, cooperates to get stone under the calculus extraction basket mirror, the most advanced summit of sacculus closely coincide with the seal wire and has hydrophilic coating, easily avoids biliary tract wall fish tail through narrow portion, the sacculus inner chamber is equipped with the side opening when make annotating liquid sacculus can even expansion, and the stone operation is got to the capable choledochus of cooperation cholangioscope, and this balloon dilation catheter simple structure, operation are feasible, can create good conditions for calculus extraction basket on next step gets stone through the expansion position to it is painful effectively to alleviate operation burden and patient.
