SEALED SURGICAL ACCESS DEVICE

摘要

A surgical access device (50) facilitates passage of a surgeon's hand through an incision in a body wall and into a body cavity. The device includes a first retention member (55) disposed exteriorly of the body wall, a second retention member (52) disposed interiorly of the body wall, and an elastomeric sleeve (75). This sleeve has a central section (53) stretchable radially to form an instrument seal around the surgeon's hand, and stretchable axially to form a zero seal in the absence of the surgeon's hand. Stretching of the sleeve (86) is facilitated by varying the size of the first retention member (55).
