Abstract

A surgical instrument includes a body, at least one user input feature, an elongate shaft, a needle applier, and a motor. The needle applier includes a needle and a drive assembly coupled to the needle. The drive assembly is configured to drive the needle along an orbital path about a rotation axis that is transverse to the longitudinal axis of the shaft, in response to an actuation of the user input feature. The motor is configured provide motion to the needle applier to thereby actuate the drive assembly.
