摘要：
Rotation knob assemblies for handle assemblies of surgical instruments rotatably support a laparoscopic end effector relative to a housing of the handle assemblies. The rotation knob assemblies may include friction reducing screws, bearing members, snap rings, and/or bearing assemblies to facilitate rotation of an outer knob relative to an inner collar.
