ADAPTER ASSEMBLY FOR SURGICAL DEVICE

摘要

An adapter assembly for connecting an end effector to a surgical instrument includes first, second, and third drive assemblies configured for converting rotational motion into linear motion. Each of the second and third drive assemblies includes a pair of rotatable drive shafts for longitudinally advancing and retracting respective second and third drive members.
