摘要：
Devices, methods, and systems provide a surgical access device comprising an internal retractor device integrated with or coupled to a body wall or wound retractor. The wound retractor retracts an opening in a body wall into a body cavity, while the internal retractor permits a user to control the positions of internal structures within the body cavity, thereby permitting a user to define a surgical field. Embodiments of the internal retractor are adjustable.
