Abstract
A modular surgical instrument is provided that includes a tower having a first end, a second end and a ratchet segment between the first end and the second end. The instrument includes a ratchet reduction mechanism. The ratchet reduction mechanism includes a ratchet lever, a linear ratchet rack integrated into a ratchet segment of the tower at a location between the first end and the second end, and a ratchet collar coupled to the ratchet lever. The ratchet collar is configured to slide along the ratchet segment by application of an applied force. The instrument includes a reducer that may be affixed to the ratchet reduction mechanism. The reducer is configured to move in unison with the slide of the ratchet collar.
