摘要：
A surgical access device is adapted for performing laparoscopic surgical procedures with at least one instrument passing through the surgical access device and through an incision in the abdominal wall of a patient with the abdominal cavity pressurized with an insufflation gas. The surgical access device comprises an access seal. The material of the access seal is adapted to form a seal to generally maintain insufflation pressure within the abdominal cavity. At least one opening is formed through the material of the access seal between a proximal portion and a distal portion of the access seal. The at least one opening when operatively disposed is in communication with the incision and forms a working channel between a location external to the abdominal wall and a location internal to the abdominal wall. The material of the access seal conforms to a surface of an instrument inserted through the working channel.
