Abstract:
An atrial septostomy device, comprising a first tube body (1), a second tube body (2) and an auxiliary assembly (5), wherein a distal end of the second tube body (2) is connected to a cutter (4); the cutter (4) is provided with a cavity (41) in communication with a tube cavity of the second tube body (2); and the first tube body (1) is slidably arranged in the second tube body (2) and the cutting knife (4) in a penetrating manner. The auxiliary assembly (5) comprises a push-pull rod (51) and a cutting auxiliary member (52), wherein the push-pull rod (51) is slidably arranged in the first tube body (1) in a penetrating manner; a proximal end of the cutting auxiliary member (52) is connected to a distal end of the first tube body (1); a distal end of the cutting auxiliary member (52) is connected to a distal end of the push-pull rod (51); and the push-pull rod (51) can slide relative to the first tube body (1), such that the cutting auxiliary member (52) is switched between an unfolded state and a stretched state. When the cutting auxiliary member (52) is in the stretched state, the cutting auxiliary member can be accommodated inside the cavity (41).
