1. A medical device for cutting a suture during a minimally invasive procedure, comprising:
an elongate shaft having a proximal end, a distal end, and a central longitudinal axis extending from the proximal end to the distal end;
a handle housing disposed at the proximal end of the elongate shaft; and
a cutting blade disposed proximate the distal end of the elongate shaft;
wherein a proximal portion of the handle housing includes an actuation mechanism including a lever arm having a first portion disposed outside of the handle housing and extending distally from the proximal portion of the handle housing; wherein the actuation mechanism includes a rack axially slidable parallel to the central longitudinal axis and at least one gear engaged with the rack; wherein the at least one gear includes a semi-circular profile;
wherein translation of the first portion of the lever arm relative to the handle housing axially translates the cutting blade within the elongate shaft.
