摘要：
The device can include a first member connected to a second member via junctions. The members can be statically or pivotally connected at the junctions via arms extending from cross-beams of the members. The junctions can be configured to provide a biasing force. Methods of using the device may include collapsing the device and inserting it through an incision, allowing the biasing force to cause continuous traction and counter-traction adjacent to a leading dissection edge so that retraction of the skin from the tissue can be facilitated during a surgical procedure.
