Device and procedure for minimally invasive closure of atrial septal defect without cardiopulmonary bypass

摘要

A surgical device for closure Atrial Septal Defect (ASD) with minimally invasive approach includes a head portion which is movable and includes a distal jaw that is distal relative to a person holding the surgical device, a guide rod which drives the distal jaw, and a plurality of first suture-guide channels attached to the distal jaw, and a body portion which is stationary and includes a cylindrical base, a proximal jaw attached to the cylindrical base, and a plurality of second suture-guide channels attached to the proximal jaw, in which the guide rod drives the distal jaw to pass a pericardium patch through a patient's ASD while the proximal end remains extracorporeal, and the first suture-guide channels and the second suture-guide channels guide a suture thread to suture the pericardium patch onto an ASD rim.
