Abstract
A surgical tool includes a surgical blade configured to be moved to form an incision. The surgical tool also includes a wire configured to cause movement of the surgical blade. The surgical tool further includes an actuator configured to shorten a length of the wire to cause the movement of the surgical blade. The surgical tool could be configured to move the surgical blade in a first direction and then in a second direction in response to a single shortening of the wire. Also, the wire could represent a first wire, the surgical tool could include a second wire, and the surgical tool could be configured to move the surgical blade in a first direction in response to shortening the first wire and to move the surgical blade in a second direction in response to shortening the second wire.
