Abstract
Several methods to reduce surgical site infections include inserting a surgical access device into an incision, retracting tissue, and introducing fluid into the surgical access device such that the fluid exits the surgical access device and irrigates a surgical site. Other methods do not include introducing fluid into a surgical access device but include suctioning a fluid into the surgical access device and removing the fluid from the body.
Claims48
A method for irrigating a surgical site in patient's body, said method comprising:
- providing a surgical access device, wherein the surgical access device comprises a first retention member, a second retention member, and a pliable membrane coupled to the first and second retention members, wherein the pliable membrane comprises an inner layer and an outer layer joined together at a plurality of locations, wherein the plurality of joined locations form a quilted pattern, and wherein the outer layer comprises a plurality of perforations;
- advancing the first retention member into the body through an incision;
- disposing the second retention member outside the body;
- irrigating the surgical site with fluid delivered from the plurality of perforations.

- advancing the first retention member into the body through an incision;
- disposing the second retention member outside the body;
- irrigating the surgical site with fluid delivered from the plurality of perforations.

- maintaining patency between the inner and the outer layers by providing a porous or non-porous material disposed therebetween, wherein the porous or non-porous material maintains patency when a compressive force is applied to the inner and the outer layers;
- advancing the first retention member into the body through an incision;
- disposing the second retention member outside the body;
- irrigating the surgical site with fluid delivered from the plurality of perforations.

- maintaining patency between the inner and the outer layers by providing a compressible or an incompressible material disposed therebetween, wherein the compressible or incompressible material maintains patency when a compressive force is applied to the inner and the outer layers;
- advancing the first retention member into the body through an incision;
- disposing the second retention member outside the body;
