摘要： Various systems and methods for controlling an ultrasonic surgical instrument according to the location of tissue grasped within an end effector are disclosed. A control circuit can be configured to apply varying power levels, via a generator, to an ultrasonic transducer driving an ultrasonic electromechanical system to oscillate an ultrasonic blade. Further, the control circuit can measure impedances of the ultrasonic transducer corresponding to the varying power levels and determine a location of tissue positioned within the end effector according to a difference between the impedances of the ultrasonic transducer relative to a threshold.

摘要： An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.

摘要： Methods, devices, and systems related to electrosurgical tools are provided. The electrosurgical tools can include an electrode formed of non-linear resistance material for allowing energy to be transmitted to the electrode for heating the electrode or to tissue adjacent the electrode for heating the tissue. Such transmission of the energy can depend upon a characteristic of the electrical energy, such as voltage or frequency of the energy, which can affect the resistance properties of the electrode.

摘要： An ultrasonic surgical shears includes an ultrasonic surgical blade, a clamping arm operable to open and close toward the blade, and a tissue pad attached to the clamping arm. A method for sealing a blood vessel of a patient includes obtaining an ultrasonic surgical shears and positioning the blood vessel between the blade and the tissue pad. The clamping arm is operated to exert an average coaptation pressure between and including 120 psi and 210 psi. The blade is ultrasonically vibrated to transect and seal the blood vessel.

摘要： A surgical device. The surgical device may comprise a transducer configured to provide vibrations along a longitudinal axis and an end effector coupled to the transducer and extending from the transducer along the longitudinal axis. The surgical device also may comprise a lower jaw extending parallel to the end effector. The lower jaw may comprise a clamp face extending toward the longitudinal axis. Also, the lower jaw may be slidable relative to the end effector to bring the clamp face toward a distal end of the end effector.

摘要： An electrosurgical device is disclosed. The electrosurgical device includes a handle, a shaft extending distally from the handle, and an end effector coupled to a distal end of the shaft. The end effector comprises a first electrode and a second electrode. The second electrode includes a first position and a second position. The second electrode is configured to move from the first position to the second position when a force is applied to the end effector by a tissue section. The first electrode and the second electrode define a treatment area when the second electrode is in the second position.
