Abstract: Various aspects of a generator, ultrasonic device, and method for estimating and controlling a state of an end effector of an ultrasonic device are disclosed. 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 receives 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. The control circuit estimates the state of the end effector of the ultrasonic device and controls the state of the end effector of the ultrasonic device based on the estimated state.

Abstract: A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The body comprises a pivotal trigger. The shaft couples the end effector and the body together. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with the ultrasonic transducer. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue. Pivotal movement of the trigger causes movement of the clamp arm. The trigger includes a compliant feature configured to limit the amount of force delivered to tissue by the clamp arm. The flexible feature may comprise a flexible band, living hinge, a series of living hinges, or a flexible tab.

Abstract: Disclosed is a surgical instrument with an end-effector adapted and configured to deliver a plurality of energy modalities to tissue at a distal end thereof. The energy modalities may be applied simultaneously, independently, or sequentially. A generator is electrically coupled to the surgical instrument and is configured to supply a plurality of energy modalities to the end-effector. In one aspect, the generator is configured to supply electrosurgical energy (e.g., monopolar or bipolar radio frequency (RF) energy) and ultrasonic energy to the end-effector to allow the end-effector to interact with the tissue. The energy modalities may be supplied to the end-effector by a single generator or multiple generators.

Abstract: The present disclosure is directed to end effectors. An end effector includes an outer shaft extending along a longitudinal axis and an inner shaft partially located within the outer shaft. The end effector may include an ultrasonic blade. The inner shaft may include biased and unbiased portions. The inner shaft and outer shaft may be translatable relative to one another. At one translatable position, the biased portion of the inner shaft may be located within the outer shaft and the unbiased portion may be substantially straight along the longitudinal axis. At another translatable position, the biased portion of the inner shaft may be located outside of and distally positioned from the outer shaft such that the biased portion of the inner shaft is bent away from the longitudinal axis.

Abstract: An apparatus comprises a body, a shaft assembly, an end effector, and a shield member. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is movable toward the ultrasonic blade to compress tissue against the ultrasonic blade. The shield member is selectively movable from a first position to a second position in response to movement of the clamp arm toward the ultrasonic blade. The shield member is configured cover at least a first portion of the ultrasonic blade in the first position. The shield member is configured to uncover the first portion of the ultrasonic blade in the second position.

Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.

Abstract: An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation and clamping of tissue during surgical procedures. An elongated portion of the instrument can be configured for endoscopic applications and has an outside diameter of less than 6 mm. The construction includes a clamping mechanism, including a clamp arm pivotally mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces, exceeding 4 pounds when the trigger is fully closed. The clamping mechanism includes a force-limiting mechanism that effectively smooths out abusive tissue forces.

Abstract: An apparatus includes a shaft assembly, an ultrasonic blade, and a clamp assembly. The shaft assembly includes an acoustic waveguide operable to transmit ultrasonic vibrations to the blade. The clamp assembly includes a clamp arm pivotable toward and away from the blade about a pivot axis, to clamp tissue between the clamp arm and the blade. A rotation feature may provide rotation of the blade relative to the clamp arm about the longitudinal axis of the waveguide. Alternatively, the rotation feature may provide rotation of the clamp arm relative to the blade about the longitudinal axis. The rotation feature may be driven based on pivotal positioning of the clamp arm relative to the blade about the pivot axis. The rotation feature may selectively lock and unlock the angular position of either the blade or the clamp arm about the longitudinal axis at any of a number of predetermined angular positions.

Abstract: A generator, ultrasonic device, and method for controlling a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency. The control circuit controls the temperature of the ultrasonic blade based on the inferred temperature
