Abstract
A retraction device adapted to retract tissue is provided, comprising at least one pair of opposed retraction members, with each retraction member being capable of operably engaging the tissue to be retracted. A drive mechanism is operably engaged with at least one of each pair of retraction members for separating one of each pair of retraction members from the other to retract the tissue. A measuring device is operably engaged with at least one of the drive mechanism and one of each pair of retraction members, for determining and/or controlling a magnitude and/or rate of a force and/or strain imparted to the tissue by the drive mechanism via the retraction members as the tissue is being retracted. Associated devices and methods are also provided.
