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 pair of rotatable drive shafts for longitudinally advancing and retracting respective second and third drive members.
Claims20
An adapter assembly for operably connecting an end effector to a surgical instrument, the adapter assembly comprising:
- a proximal portion configured for operable engagement with a surgical instrument;
- a distal portion configured for operable engagement with an end effector;
- an intermediate portion extending between the proximal portion and the distal portion;
- a drive coupling assembly disposed within the proximal portion;
- a first drive assembly operably connected to the drive coupling assembly, the first drive assembly including a rotatable drive shaft and defining a longitudinal axis;
- a second drive assembly operably connected to the drive coupling assembly, the second drive assembly including a first pair of rotatable drive shafts, each shaft of the first pair of rotatable drive shafts extending between the proximal and distal portions, wherein a first shaft of the first pair of rotatable drive shafts rotates in a first direction and a second shaft of the first pair of rotatable drive shafts rotates in a second direction;
- and
- a third drive assembly operably connected to the drive coupling assembly, the third drive assembly including a second pair of rotatable drive shafts, each shaft of the second pair of rotatable drive shafts extending between the proximal and distal portions, wherein a first shaft of the second pair of rotatable drive shafts rotates in a first direction and a second shaft of the second pair of rotatable drive shafts rotates in a second direction.
