摘要

Devices and methods for retracting tissue, such as bowels and organs, within the body of a patient are generally disclosed. In particular, the present disclosure describes surgical retractors having a series of intersecting strands defining openings there between, wherein the openings are enlargeable by slidable passage of the strands relative to one another. The present disclosure also teaches surgical retractors having a frame that defines a central opening and a supporting structure extending across the central opening and defining a plurality of openings, wherein the frame extends through the openings.
