摘要： 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

摘要： A differential dissecting instrument for differentially dissecting complex tissue is disclosed. The differential dissecting instrument comprises a handle and an elongate member having a first end and a second end, wherein the first end is connected to the handle. The differential dissecting instrument comprises a differential dissecting member configured to be rotatably attached to the second end and further comprises at least one tissue engaging surface. The differential dissecting instrument comprises a mechanism configured to mechanically rotate the differential dissecting member around an axis of rotation, thereby causing the at least one tissue engaging surface to move in at least one direction against the complex tissue. The at least one tissue engaging surface is configured to selectively engage the complex tissue such that the at least one tissue engaging surface disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.

摘要： Embodiments disclosed include methods and devices for blunt dissection, which differentially disrupt a patient's soft tissues while not disrupting that patient's firm tissues. In one embodiment, a differential dissecting instrument for differentially dissecting complex tissue disclosed. The differential dissecting instrument comprises a handle, a central longitudinal axis, and an elongate member having a proximal end and a distal end. The differential dissecting instrument also comprises a differential dissecting member configured to be rotatably attached to the distal end, the differential dissecting member comprising at least one tissue engaging surface, a first torque-point, the first torque-point disposed to a first side of the axis of rotation of the differential dissecting member, and a mechanism, configured to mechanically rotate the differential dissecting member around the axis of rotation thereby causing the at least one tissue engaging surface to move in at least one direction against the complex tissue. The mechanism comprises at least one force-transmitting member possessing a distal end and a proximal end, the distal end being attached to the first torque-point member. The proximal end of the at least one force-transmitting member is attached to a motive source configured to oscillate the differential dissecting member. Further, the at least one tissue engaging surface is configured to selectively engage the complex tissue such that when the differential dissecting member is pressed by the surgeon into the patient's complex tissue, the at least one tissue engaging surface moves across the complex tissue and the at least one tissue engaging surface disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.
