摘要:
A soft material retractor includes at least two soft actuators, each actuator having at least one pressurizable interior space, wherein the actuator has a first flexible resting state and a second stiffer pressurized state; and a flexible sheet spanning the actuators such that the actuators can be spaced apart from each other by a distance selected to displace a volume of material of a body cavity. The retractor can be uses for holding open wounds or incisions, with trochars, or to displace anatomical features such as organs within a body cavity.
