    Abstract: Various embodiments are directed to an electrosurgical systems and methods for providing an electrosurgical signal to a patient. An electrosurgical signal defining a plurality of pulses may be provided to first and second electrodes. A first reading may be received indicating an impedance between the first and second electrodes taken at a first point of a first pulse of the electrosurgical signal. A second reading may indicate the impedance a first point of a second pulse of the electrosurgical signal, where the first point of the first pulse and the first point of the second pulse are at equivalent positions within the first and second pulses. Based on a comparison of the first reading and the second reading, a short circuit may be determined and a signal indicating the short circuit may be generated.

    Abstract: A surgical instrument is provided that can comprise and end effector including two jaws and a cutting member configured to move between the jaws. In at least one embodiment, one or both of the jaws may be flexible, such that a jaw is configured to flex when gripping tissue. Further, at least one of the jaws may include a thin cross-sectional area such that the jaw flexes when gripping tissue. Additionally, in at least one embodiment, one or more compression elements may extend from the cutting member and may be configured to cause the jaws to close when the cutting member is advanced. The compression elements may comprise a roller and/or a low-friction material. Moreover, in at least one embodiment, one or both of the jaws may be precurved, away from the cutting member's longitudinal axis. Accordingly, in various embodiments, the overall force required to advance the cutting member and/or close the jaws may be reduced.
