摘要： An end effector for an electrosurgical instrument is disclosed which comprises a first jaw comprising a first energy delivery surface, a first distal end, and a first proximal end; and a second jaw comprising a second energy delivery surface, a second distal end, and a second proximal end, wherein the first energy delivery surface comprises a first curved portion that is outwardly curved, and the second energy delivery surface comprises a second curved portion that is inwardly curved. The first jaw or the second jaw is configured for pivotal movement between an open position and a closed position. In the open position, the first and second distal ends are separated apart. In the closed position, the first and second distal ends are in proximity. The end effector also comprises an electrically conductive member which protrudes from either the first or second jaw.

摘要： Various systems and methods for determining the state of an end effector of an ultrasonic surgical instrument are disclosed. A control circuit can be configured to measure a complex impedance of an ultrasonic electromechanical system including an ultrasonic blade and compare the measured complex impedance to reference complex impedance patterns that each correspond to a state of the end effector. Accordingly, the control circuit can further be configured to determine the state of the end effector according to which of the plurality of reference complex impedance patterns the measured complex impedance corresponds.

摘要： An end-effector configured to grasp tissue is disclosed herein. The end-effector includes an ultrasonic blade configured to transfer ultrasonic energy to the tissue and a clamp arm. The clamp arm includes a clamp arm pad including an electrically conductive material and an electrically non-conductive material. The clamp arm pad is configured as an electrode of a radiofrequency energy circuit, wherein the electrode is configured to transfer radiofrequency energy through the tissue to a return electrode of the radiofrequency energy circuit, and wherein the electrically non-conductive material is configured to reduce the possibility of an electrical short between the electrically conductive material and the ultrasonic blade as the clamp arm pad degrades throughout the usable life of the end effector.

The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and to electrically couple to a pole of an electrical generator. The clamp arm incudes a clamp jaw, a cantilever electrode, and a clamp arm. The cantilever electrode is biased in a direction toward the clamp jaw and the clamp arm includes a retainer to oppose a biasing force and maintain the cantilever electrode in a substantially flat configuration relative to the ultrasonic blade. A skirt may be disposed around the clamp jaw. The clamp arm pad may include multiple support elements arranged in multiple rows to support the cantilever electrode.

摘要： Various aspects of a generator, ultrasonic device, and method for estimating a state of an end effector of an ultrasonic device are disclsoed. The ultrasonic device includes an electromechanical ultrasonic system defined by a predetermined resonant frequency, including an ultrasonic transducer coupled to an ultrasonic blade. A control circuit measures a complex impedance of an ultrasonic transducer, wherein the complex impedance is defined as Z g ( t ) = V g t I g t . The control circuit receivs a complex impedance measurement data point and compares the complex impedance measurement data point to a data point in a reference complex impedance characteristic pattern. The control circuit then classifies the complex impedance measurement data point based on a result of the comparison analysis and assigns a state or condition of the end effector based on the result of the comparison analysis.

摘要： 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.
