SURGICAL DEVICE FOR CLOSURE OF ATRIAL SEPTAL DEFECT WITH MINIMALLY INVASIVE APPROACH

摘要

A method of providing a surgical device for closure of Atrial Septal Defect (ASD) with minimally invasive approach includes a head portion that includes a distal jaw being 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. A lever drives the distal jaw away from the proximal jaw such that the distal jaw and the proximal jaw are spaced on different sides of an ASD hole. After a suture thread sutures a pericardium patch, the lever pulls the distal jaw backward toward the proximal jaw such that the first suture-guide channels couple with the second suture-guide channels.

1. A surgical device for closure Atrial Septal Defect (ASD) with minimally invasive approach, said device comprising:
a head portion which is movable and comprises:
a distal jaw being distal relative to a person holding the surgical device;a guide rod which drives the distal jaw; anda plurality of first suture-guide channels attached to said distal jaw; and a body portion which is stationary and comprises:
a cylindrical base;a proximal jaw attached to said cylindrical base; anda plurality of second suture-guide channels attached to said proximal jaw, wherein the guide rod drives the distal jaw to pass a pericardium patch through a patient's ASD while the proximal jaw remains extracorporeal, and wherein the first suture-guide channels and the second suture-guide channels guide a suture thread to suture the pericardium patch onto an ASD rim, wherein said each of the first suture-guide channels is spaced apart from an adjacent one of the first suture-guide channels such that the arm of said each of the first suture-guide channels is oriented at a predetermined angle with respect to an arm of said adjacent one of the first suture-guide channels, wherein each of the second suture-guide channels comprises an arm which connects a center portion of each of the second suture-guide channels to the proximal jaw, wherein said each of the second suture-guide channels is spaced apart from an adjacent one of the second suture-guide channels such that the arm of said each of the second suture-guide channels is oriented at the predetermined angle with respect to an arm of said adjacent one of the second suture-guide channels, and wherein the first suture-guide channels is oriented at the predetermined angle to the second suture-guide channels such that the first suture-guide channels couple with the second suture-guide channels.
