<P>PROBLEM TO BE SOLVED: To provide a surgical instrument. <P>SOLUTION: The surgical instrument includes a housing, an end effector, an elongated shaft, and a drive assembly. The end effector is operable from the housing to surgically manipulate tissue and has first and second opposable jaw members which are movable from an open configuration for receiving tissue to a closed configuration for manipulating tissue. The elongated shaft extends between the housing and the end effector to define a longitudinal axis. The elongated shaft further defines an aligned configuration and an articulated configuration with respect to the longitudinal axis. The drive assembly includes a first spring and a drive wire, which is configured to induce motion in the jaw members between the open configuration and the closed configuration. The drive assembly is further configured to maintain a closure pressure in the range of about 3-16 kg/cm<SP POS="POST">2</SP>between the aligned configuration and the articulated configuration. <P>COPYRIGHT: (C)2012,JPO&INPIT |
