A surgical assembly includes a surgical instrument and a holder. The surgical instrument includes an elongate body and an end effector. The elongate body has a proximal portion and a distal portion that defines a longitudinal axis therealong. The proximal portion is movable relative to the distal portion between a first condition and a second condition. In the first condition, the proximal portion is parallel to the longitudinal axis. In the second condition, the proximal portion is non-parallel to the longitudinal axis. The holder is configured to be coupled to the elongate body to selectively retain the proximal portion of the elongate body in the first condition.
