摘要：
According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly, and a follower. The drive assembly includes a first helical groove. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The follower is configured to engage the first helical groove of the drive assembly. When the follower is engaged with the first helical groove, rotation of the drive assembly in the first direction causes distal translation of the follower with respect to the drive assembly.
