Abstract
Methods and devices are disclosed to reduce tissue trauma when a physician retracts a patient's tissues for surgery. A device includes a tissue engager adapted to engage a patient's tissue, a control system adapted to control the tissue engager to deform the patient's tissue, and a sensor adapted to produce a first signal based on the deformation. The control system is further adapted to receive the first signal, perform a plurality of measurements based on the first signal over time; and compare a substantially instantaneous measurement of the first signal to a variance in the plurality of measurements over an interval of time preceding the instantaneous measurement, and detect a state of the patient's tissue based on the comparison.
