    Abstract: An ultrasonic surgical instrument includes a transducer assembly having a distal engagement member and configured to supply ultrasonic energy. A waveguide defines a longitudinal axis and has a proximal engagement member configured to threadingly engage the distal engagement member. The waveguide is configured to transmit the ultrasonic energy therealong to a distal end thereof for treating tissue. A torque member is coupled to the transducer assembly and is disposed about the longitudinal axis. The torque member is selectively rotatable about the longitudinal axis and relative to the waveguide to threadingly engage the transducer assembly and the waveguide to one another. The torque member includes a plurality of fingers pivotably coupled thereto and movable between a closed position and an open position. In the open position, each finger extends substantially perpendicularly from the longitudinal axis to define a moment arm that facilitates the engagement of the transducer assembly and the waveguide.

    Abstract: A surgical device is disclosed, and includes a pair of finger-mountable annular members, each having an electrode disposed thereon. An optical member is disposed on at least one of the pair of finger-mountable annular members and has a first set of light transmitting properties corresponding to a first set of physical parameters of at least one of the finger-mountable annular members. At least one finger-mountable annular member is configured to transition to a second set of physical parameters being different from the first set of physical parameters. The optical member is configured to transition from a first set of light transmitting properties to a second set of light transmitting properties, the second set of light transmitting properties corresponding to the second set of physical parameters, the second set of light transmitting properties being different from the first set of light transmitting properties.

    Abstract: A surgical instrument includes an end effector including first and second jaw members movable relative to one another between a first, spaced-apart position and a second position proximate tissue. In the second position, the jaw members cooperate to grasp tissue therebetween. A first optical fiber is disposed within the first jaw member and is configured to provide a first signal, and a second optical fiber is disposed within the first jaw member and is configured to provide a second signal. A controller is coupled to the first and second fibers and is configured to determine the temperature and the strain of the first jaw member as a function of the first and second signals, respectively.

    Abstract: An electrosurgical system includes jaw members having a cutting element extending therebetween and a generator configured to: provide minimal power to the cutting element to maintain a pre-dissection temperature thereof; sense a change in resistance of the cutting element and ramp up power to a dissection temperature; regulate the temperature of the cutting element by regulating power; and terminate power to the cutting element to allow the cutting element to cool to the pre-dissection temperature before providing power back to the cutting element.
