Abstract: Various embodiments are directed to surgical instruments comprising an end effector, a shaft and a jaw assembly. The end effector may comprise an ultrasonic blade extending distally substantially parallel to a longitudinal axis. The shaft may extend proximally from the end effector along the longitudinal axis. The jaw assembly may comprise first and second jaw members. The jaw assembly may be pivotable about a first axis substantially perpendicular to the longitudinal axis from a first position where the first and second jaw members are substantially parallel to the ultrasonic blade to a second position. Additionally, the first and second jaw members may be pivotable about a second axis substantially perpendicular to the first axis.

Abstract: The present invention generally provides methods and devices for controlling movement of an end effector, and in particular for causing mimicked motion between an input tool and an end effector during a surgical procedure. In an exemplary embodiment, a surgical system is provided having a master assembly with an input tool and a slave assembly with an end effector. The master assembly and the slave assembly can be coupled together by a mechanical assembly that is configured to mechanically transfer mimicked, rather than mirrored, motion from the input tool to the end effector. A floating frame is also provided and can be utilized with the surgical system. The floating frame can have a counterbalance that allows the surgical system to “float” above a patient and provide a weightless feel to movement of the surgical system. In addition, the floating frame can provide a number of additional degrees of freedom for ease of movement of the surgical system around the patient and/or the operating room.

Abstract: Surgical instruments including a shaft, a jaw assembly and an ultrasonic assembly are disclosed. The shaft may extend along a shaft axis. The jaw assembly may be coupled to a distal end of the shaft and may include a first jaw member and a second jaw member. The jaw assembly may be configured to pivot about a first axis between a first location and a second location. The first and second jaw members may be positioned substantially parallel to the shaft axis at the first location and the first and second jaw members may be positioned at an angle from the shaft axis at the second location. The ultrasonic assembly may comprise an ultrasonic blade, a waveguide, and a transducer. The ultrasonic assembly may be positioned substantially parallel to and offset from the shaft axis and may be axially translatable to at least partially retract the ultrasonic blade within the shaft.
