Abstract
Surgical tools that are capable of both manipulating a needle and cutting surgical thread during a suturing operation can sometimes be problematic due to inadvertent severing of the surgical thread. Surgical tools capable of exposing a bladed cutting surface only when severing of surgical thread is desired can substantially alleviate this issue. Such surgical tools may comprise an end effector comprising an end effector axle, a first jaw and a second jaw rotatably mounted to the end effector axle, and a first cutting body having a first blade and second cutting body having a second blade. The first cutting body is configured to move in tandem with the first jaw and the second cutting body is configured to move in tandem with the second jaw, such that the first and second blades are occluded when the first and second jaws are closed or partially opened.
