Abstract

An apparatus includes an interface assembly and a shaft assembly. The interface assembly is configured for use with a robotic system and includes a first drive assembly and a mounting plate. The mounting plate includes an opening. The first drive assembly is positioned within the opening such that the first drive assembly is laterally translatable within the opening from a first position to a second position. The shaft assembly is removably coupled with the interface assembly. The shaft assembly includes an end effector and a first coupling feature. The first drive assembly of the interface assembly actuates the end effector of the shaft assembly. The first coupling feature is longitudinally aligned with the first drive assembly. The first drive assembly engages the first coupling feature of the shaft assembly when the first drive assembly is laterally translated from the first position to the second position.
