Ultrasonic surgical instruments with distally positioned jaw assemblies
First Claim
1. A surgical instrument comprising:
- an ultrasonic blade positioned at a distal end of an ultrasonic waveguide, the ultrasonic waveguide extending distally substantially parallel to a longitudinal axis;
a shaft extending proximally from the ultrasonic blade along the longitudinal axis; and
a jaw assembly, wherein the jaw assembly comprises;
a wrist member pivotable about a wrist pivot axis substantially perpendicular to the longitudinal axis from a first position where the wrist member is substantially parallel to the ultrasonic blade to a second position where the wrist member is pivoted away from the ultrasonic blade, wherein the wrist pivot axis is offset from the ultrasonic blade in an offset direction, wherein the offset direction is perpendicular to the longitudinal axis;
a first jaw member extending distally from and pivotably coupled to the wrist member, wherein the first jaw member is pivotable about a jaw pivot axis substantially perpendicular to the wrist pivot axis; and
a second jaw member extending distally from and pivotably coupled to the wrist member, wherein the second jaw member is pivotable about the jaw pivot axis, and wherein the first and second jaw members are further pivotable about the jaw pivot axis relative to one another from an open position where the first and second jaw members are pivoted away from one another to a closed position where the first and second jaw members are pivoted towards one another.

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.
