Abstract
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 cam assembly for longitudinally advancing and retracting respective second and third drive members.
Claims21
An adapter assembly for operably connecting an end effector to a surgical instrument, the adapter assembly comprising:
- a drive coupling assembly;
- a first drive assembly operably connected to the drive coupling assembly, the first drive assembly including a drive screw;
- a second drive assembly operably connected to the drive coupling assembly, the second drive assembly including a first cam assembly and a second drive member, the first cam assembly including a first eccentric cam member in operable engagement with the second drive member;
- and
- a third drive assembly operably connected to the drive coupling assembly, the third drive assembly including a second cam assembly and a third drive member, wherein at least one of the first or second drive assemblies operates independently from the third drive assembly and the drive screw, the second drive member, and the third drive member are coaxial.
