摘要：
According to an aspect of the present disclosure, an end effector for use withasurgical device is provided. The end effector includes a drive assembly, adriver, a needleassembly, and a follower. The drive assembly includes a first helical groove.Rotation of thedrive assembly in a first direction causes distal translation of the driverwith respect to thedrive assembly. The needle assembly is disposed in mechanical cooperation withthe driver.Distal translation of the driver causes a corresponding distal translation ofthe needleassembly. The follower is configured to engage the first helical groove of thedriveassembly. When the follower is engaged with the first helical groove, rotationof the driveassembly in the first direction causes distal translation of the follower withrespect to thedrive assembly.
