Bone reduction forceps provide both continuous and discrete adjustment of force. A worm gear rotatably attached to one arm of the forceps engages a rack attached to another arm of the forceps to provide both the continuous and discrete force adjustment. Buttress threads on the worm and/or the rack allow for rapid closure by squeezing the handles of the forceps. Rotating the worm gear allows for fine adjustment of closing force. A five-bar linkage provides increased mechanical advantage and an extra degree of freedom, compared to conventional forceps. Interchangeable tips provide flexibility, allowing a user to customize the forceps to a task or the user's preferences.
