In this embodiment, the sealing body 13 is a medical patch structure (may be circular), and is fixed on the inner wall of the heart by a sewing manner. Meanwhile, the drainage catheter 12 is of a flexible pipe structure; at this time, the sealing body 13 and the drainage catheter 12 can be made of terylene, gore-Tex and other materials, and the sealing body and the drainage catheter can be manufactured integrally; the drainage catheter 12 and the other end may be sutured to the stent graft 112.
In this embodiment, the connecting bracket body 111 is provided with a positioning member 113, and the positioning member 113 is used for fixing the pulmonary vein connecting bracket 11 in an ectopic drainage pulmonary vein, so as to effectively prevent the pulmonary vein connecting bracket 11 from being separated. The positioning member 113 may have various structures as appropriate, for example, the positioning member 113 includes a plurality of buckles circumferentially arranged along the left end portion of the connection bracket body 111, the buckles being outwardly displayed with the tail portions thereof facing the left or right side of the connection bracket body 111.
The ring buckle may be a portion extending outwards at a specific portion of the connection bracket body 111, for example, may be semicircular or triangular; the ring buckle has certain elasticity and can be clamped on the inner wall of the pulmonary vein, so that the pulmonary vein connecting bracket 11 is prevented from moving reversely.
Fifth embodiment:
the complexity part type pulmonary vein ectopic drainage correction system for cardiac surgery provided by the embodiment is improved on the basis of any one of the structures shown in the first to fourth embodiments, so that the same structure and principle between the two are not repeated here.
In this embodiment, as shown in fig. 9, the correction system further includes a clamping forceps 3, where the clamping forceps 3 is used in cooperation with the pulmonary vein connection bracket 11, and is mainly used for placing the pulmonary vein connection bracket 11 into a pulmonary vein.
