Abstract
A method and apparatus to achieve hemostasis along a staple line by utilizing a pledget material positioned adjacent at least one surface of tissue. A line of staples extends through the tissue and the pledget material. The pledget material substantially uniformly distributes pressure along the staple line and thereby causes substantial hemostasis along the tissue cut. The pledget material may also absorb blood that may escape from a partially open blood vessel.
Claims15
Apparatus for anastomosing the adjacent walls of two organ sections, comprising:
- means for clamping the adjacent walls of the organ sections together with a pledget material that is absorbent and entirely absorbable, said pledge material being positioned between said clamping means and the adjacent surface of at least one of the organ section walls;
- stapling means for forming at least one pair of spaced apart parallel lines of surgical staples extending through the walls of the organ sections and the pledget material so as to substantially uniformly distribute pressure along the lines of the staples;
- and
- blade means for cutting the walls of the organ sections and the pledget material between the lines of surgical staples while said staples are extended through said walls of the organ and said pledget material so as to the close open blood vessels and cause substantial hemostasis along the cut in the walls of the organ sections.
A method of achieving hemostasis along a tissue cut having open blood vessels during the resection of tissue sections, comprising:
- positioning a pledget material that is absorbent and entirely absorbable adjacent at least one surface of the tissue;
- and
- forming at least one line of surgical staples extending through the tissue and the pledget material so as to substantially uniformly distribute pressure along the staple line closing the open blood vessels and thereby causing substantial hemostasis along the tissue cut.
A method of anastomosing the adjacent walls of two organ sections, comprising the steps of:
- clamping the adjacent walls of the organ sections together with a pledget material that is entirely absorbent and absorbable positioned adjacent the surface of at least one of the organ section walls;
- forming at least one pair of spaced apart parallel lines of surgical staples extending through the walls of the organ sections and the pledget material so as to substantially uniformly distribute pressure along the lines of staples;
- and
- directing a sharp blade between the parallel lines of surgical staples to cut the walls of the organ sections and the pledget material while said staples are extended through said walls of the organ and said pledget material so as to close the open blood vessels and cause substantial hemostasis along the cut in the walls of the organ sections.
