Abstract: Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.

Abstract: An instrument including a first arm, a second arm, and a blade. The first arm includes a lumen in communication with a source of irrigation fluid and one or more outlets in communication with the lumen for delivering the irrigation fluid to a surgical site. The instrument is switchable between a first configuration and a second configuration. In the first configuration, the instrument is configured to deliver a first therapy current through a distal end of the first arm, a distal end of the second arm, or both. In the second configuration, a distal end of the blade extends beyond the distal end of the first arm and beyond the distal end of the second arm.

Abstract: A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot.

Abstract: An instrument including working arms and a moveable member. The working arms include a first arm, a second arm, a first electrode located on the first arm, and a second electrode located on the second arm. The moveable member includes a passive circuit element, a first terminal, and a second terminal. The moveable member is moveable to a first position and a second position.
