摘要:
Methods and devices are disclosed to reduce tissue trauma when a physician retracts a patients tissues for surgery. A device includes a tissue engager adapted to engage a patients tissue, a control system adapted to control the tissue engager to deform the patients 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 patients tissue based on the comparison
