- a staple jaw shaped as a rod having a first working end and a second end;
a handle of said staple jaw located at said second end opposite to said working end of the staple jaw;
a hinge joint located at said working end of said staple jaw;
a supporting jaw shaped as a rod having a first end and a second end, and associated with said staple jaw through said first end by means of said hinge joint;
said hinge joint enabling said supporting jaw to rotate through 180 degrees with respect to said staple jaw so that when said suturing instrument is in the drawn-apart position, said supporting jaw is in fact an extension to said staple jaw, and when said suturing instrument is in the drawn-together position, said supporting jaw is set parallel to said staple jaw;
a mechanism for turning said supporting jaw relative to said staple jaw;
a lever of said turning mechanism, having a pivot pin located on said handle;
a link of said turning mechanism, having a first end and a second end, said link being held, through said first end, to the arm of said lever and through said second end, to said supporting jaw;
slots adapted to accommodate staples and located at said working end of said staple jaw;
depressions for bending the legs of said staples, located on said supporting jaw, the number of said depressions being equal to the number of said slots, each of said depressions being arranged opposite to said respective slot when said instrument is in said drawn-together position;
