    Abstract: An end-effector is disclosed including an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator and a clamp arm including a clamp jaw and a cantilever electrode fixed to the clamp jaw. The cantilever electrode is configured to electrically couple to an opposite pole of the electrical generator. The clamp arm may include an I-beam shaped clamp arm pad and the cantilever electrode is disposed between the I-beam. The clamp jaw, the cantilever electrode, and the clamp arm pad may define recesses along a length coinciding with the ultrasonic blade. The clamp arm pad may be fixed to the clamp jaw and disposed between the clamp jaw and the cantilever electrode and may extend beyond the surface of the cantilever electrode. The clamp arm may include a stationary gap setting pad and movable floating gap setting pads.

    Abstract: An apparatus includes a shaft assembly and an end effector. The shaft assembly includes a first coupling member and a second coupling member. The first coupling member and the second coupling member are configured to flex toward each other from a first position to a second position. The first coupling member and the second coupling member define a pivot axis in the first position. The end effector includes an ultrasonic blade and a clamp arm. The clamp arm is configured to couple or decouple with the shaft assembly when the first coupling member and the second coupling member are in the second position. The clamp arm is configured to pivot toward and away the ultrasonic blade about the pivot axis when the first coupling member and the second coupling member are in the first position.

    IPC: A61B17/32

    Abstract: An ultrasonic surgical instrument is disclosed including an end effector, a shaft assembly extending proximally from the end effector, and a housing extending proximally from the shaft assembly. The end effector includes a clamp arm assembly pivotable between an open position and a closed position. The clamp arm assembly includes a clamp arm including a slot, a tissue pad secured to the clamp arm, and a tab. The tissue pad includes a flange positioned in the slot. The tissue pad extends proximally to a proximal end. The tab is positioned to engage the proximal end to stop proximal displacement of the tissue pad relative to the clamp arm. Relative movement between an outer tube and an inner tube is configured to pivot the clamp arm assembly. Actuation of a trigger is configured to effect relative movement between the inner tube and the outer tube.

    Abstract: A surgical apparatus comprises a body, a shaft assembly, and an end effector. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with an ultrasonic transducer via an acoustic waveguide that extends through the shaft assembly. The clamp arm is configured to pivot about a first pivot point toward and away from the ultrasonic blade along a first angular path from a first position to a second position to thereby provide a tissue sealing mode of operation. The clamp arm is further configured to pivot about a second pivot point toward and away from the ultrasonic blade along second angular path from the second position to a third position to thereby provide a tissue cutting and sealing mode of operation. The second pivot point is proximal to the first pivot point.

    Abstract: A radio frequency (RF) instrument may include a method of classifying a tissue in live time. The method may include activating the instrument for a first period of time T1 when the RF instrument contacts the tissue, plotting at least three electrical parameters associated with the tissue to classify the tissue into distinct groups, and applying a classification algorithm to classify the tissue into a distinct group in live time. The parameters may include an initial impedance of the tissue, a minimum impedance of the tissue, and an amount of time that the impedance slope is ˜0. The instrument may collect the parameters during a predetermined amount of time, such as within the first 0.75 seconds of the activation of the device. The classification algorithm may include a support vector machine algorithm that may use a linear, polynomial, or radial basis set.

    Abstract: An ultrasonic device may include an electromechanical ultrasonic system that includes an ultrasonic transducer coupled to an ultrasonic blade. A method of delivering energy to the ultrasonic device may include sensing a vessel type in contact with the blade, determining that the vessel type is either a vein or an artery, and delivering power to the transducer based on the vessel type. Power may be applied to the transducer at a power level P that differs from a nominal power level Pn for a period T that differs from a nominal period Tn based on the vessel. The power level P may be lower than Pn for a period T that is longer than Tn when the vessel is a vein. Alternatively, the power level P my be greater than Pn for a period T that is shorter than Tn when the vessel is an artery.
