This invention relates to a surgical device and methods for accessing and retrieving a tissue mass from a body cavity through a minimally invasive laparoscopic procedure. The device consists of a handle comprising an inner rod, which is rotatably engaged within a tubular member, and a loop adapted to hold a surgical bag. The loop comprises first and second bowed leaf elements, wherein the first bowed leaf element is attached to the inner rod and the second bowed leaf element is attached to the tubular member. The device further has a rotatable articulation, such as a hinge, joining the first and second bowed leaf elements, wherein rotation of the inner rod causes the first bowed leaf element to rotate about the articulation, such that the surgical bag may be opened and closed by rotation of the inner rod.
