Abstract

A link is positioned to pivot at the distal end of a surgical instrument shaft. The link includes a pulley portion. A first control cable that pivots the link in one direction extends out of the surgical instrument shaft and crosses the width of the instrument in a first crossing direction. The first control cable is then routed around the pulley portion of the link in a first circumferential direction. Similarly, a second control cable that pivots the link in the opposite direction extends out of the surgical instrument shaft and crosses the width of the instrument in a second crossing direction. The second control cable is then routed around the pulley portion of the link in a second circumferential direction that is opposite the first circumferential direction.
