Abstract
Surgical instruments and assemblies for sealing and cutting tissue monitor jaw angle and/or jaw clamping force to provide feedback to an operator of the surgical instrument indicative of whether the tissue is suitable clamped for sealing and/or cutting. A surgical instrument or assembly includes a jaw operable to clamp tissue, a sealing mechanism, a cutting mechanism, an actuation monitoring assembly, and a feedback assembly. The actuation monitoring assembly monitors jaw angle and/or clamping force. The feedback assembly outputs feedback to the operator, based on the jaw angle and/or clamping force, as to whether the current clamping angle and/or jaw angle is suitable for sealing and/or clamping tissue.
