Abstract
The present invention is an orthopedic trigger apparatus including a rack assembly, a trigger housing assembly and a trigger assembly. The rack assembly includes a linear rack rotatably connected to a first handle of an orthopedic instrument. The trigger housing assembly includes a trigger housing connected to a second handle of the orthopedic instrument, with a rack engagement cylinder and a spring enclosed within the trigger housing. The rack engagement cylinder includes a toothed rack. The spring contacts a second surface of the toothed rack stop, biasing a first pawled surface into meshing with the rack and preventing the rack from sliding through the trigger housing in more than one direction. Actuating the trigger assembly causes an actuator protrusion on the trigger to press against the rack engagement cylinder, moving the first pawled surface of the toothed rack stop away from the rack and allowing the rack to slide freely.
