Abstract
Abstract Approximating apparatus for surgical jaw structure is provided which effects substantially parallel approximation of first and second surgical jaw structure to permit substantially parallel working interaction therebetween. The approximating apparatus includes camming structure for engaging at least one movable jaw of the surgical jaw structure to bias that jaw toward or away from a second jaw structure in a substantially parallel manner.
