Auxiliary device for removing biliary calculi through negative pressure suction

ActiveCN106344112AEach visibleAchieve desirableSurgeryMedical devicesDevice formBiliary tract
The invention relates to an auxiliary device for removing biliary calculi through negative pressure suction. The auxiliary device for removing the calculi comprises a calculi wrapping device, a fixed seat and a stabilizing device. The alculus wrapping device is located at the near-end of the fixed seat, and the stabilizing device is reflexed on the peripheral surface of the far-end of the fixed seat. The calculi wrapping device is formed by latex and is in a skirt hemline shape. The fixed seat is made into a cylindrical transparent cap by utilizing soft or hard transparent silica gel or a rubber conduit. The stabilizing device forms an annular columnar sleeve by utilizing latex. The auxiliary device has the advantages that compared with a conventional choledochoscope calculi removing net basket, the auxiliary device genuinely achieves effects of being visible and being capable of being taken; by applying the device for removing the calculi through negative pressure suction, the biliary tract inner wall is not damaged easily, and the device is more minimally invasive; against some calculi which is difficult to take or is incarcerated, by the matching of the use of the conventional net basket, the calculi is taken more easily, and more time is saved; a disposable negative pressure suction rubber tube is combined with a conventional choledochoscope, and the auxiliary device is simple, economic, practical and easy to popularize and can be widely applied to the calculi surgery against, e.g., biliary calculi and urinary calculi.
