Abstract

The present disclosure is directed to end effectors. An end effector includes an outer shaft extending along a longitudinal axis and an inner shaft partially located within the outer shaft. The end effector may include an ultrasonic blade. The inner shaft may include biased and unbiased portions. The inner shaft and outer shaft may be translatable relative to one another. At one translatable position, the biased portion of the inner shaft may be located within the outer shaft and the unbiased portion may be substantially straight along the longitudinal axis. At another translatable position, the biased portion of the inner shaft may be located outside of and distally positioned from the outer shaft such that the biased portion of the inner shaft is bent away from the longitudinal axis.
