An electrosurgical system includes an RF current generator, a handle body, and an end effector in mechanical communication with the handle body. The end effector has a first jaw including a first electrode having a first electrode surface in electrical communication with a first terminal of the generator. The end effector also includes a second jaw including a second electrode having an essentially planar second electrode surface in electrical communication with a second terminal of the generator The first jaw includes at least one feature configured to apply an amount of a compressive force to a tissue compressed between the at least one feature and the second electrode surface that differs from an amount of a compressive force applied to the tissue compressed between the first electrode surface and the second electrode surface when the first jaw is placed in a proximate position to the second jaw.

In general, surgical devices including visual indicators thereon are provided. A user of the device therefore may quickly visually ascertain various operational details of the surgical device and/or various pieces of information about the device and/or tissue of a patient being operated on.

Surgical devices with visual indicators

Bipolar electrosurgical jaws

Surgical access devices are provided having jaw assemblies that maintain a uniform spacing between the jaws and are electrically isolated from each other in a closed configuration. The devices provided for generally include one or more electrically insulative stops associated with a tissue engaging surface of one of the jaws, with the stops being configured to engage the tissue engaging surface of the opposed jaw. The stops set a uniform spacing between the jaws in the closed configuration, and provide electrical isolation. The stops can be disposed in intermediate, proximal, and/or distal portions of the jaw(s), and can be disposed at multiple locations of the jaw(s). The stops can come in many different forms and can be associated with jaws using a variety of techniques. Further, other embodiments, as well as methods for clamping tissue by providing a uniform gap between jaws during each closure stroke, are also provided.
