A surgical device includes a ratchet having pawls biased to a locked position in which the pawls prevent movement of a ratchet body along a rack. A pinion and a cam disc of the ratchet cooperate to selectively release the pawls from the rack and impart ratcheted movement of the ratchet body along the rack. Rotation of a handle rotates the pinion and the cam disc. Due to such rotation, the cam disc periodically releases the pawls from the rack, and the pinion imparts movement of the ratchet body along the rack during the periodic release of the pawls.

Surgical retractor and bidirectional ratchet

A surgical instrument includes a rack, a first arm coupled to the rack, a second arm coupled to the rack, a first tower coupled to the first arm, and a second tower coupled to the second arm. The first tower comprises an upper end, a lower end, and a track between the upper end and the lower end. A channel of the first arm is configured to receive the track of the first tower and selectively position the first arm along the track of the first tower. The lower end of the first tower is configured to snap onto a pedicle screw and to disengage from the pedicle screw in response to a removal tool being inserted into the first tower.
