Abstract

A retractor includes a first arm, a second arm, and a translating member. The first arm comprises a proximal portion configured to retain a first retractor member and a distal portion configured to rotate relative to the proximal portion about a first axis. The second arm is configured to retain a second retractor member, such that rotation of the distal portion about the first axis causes the first retractor member to pivot toward or away from the second retractor member when the first retractor member and the second retractor member are coupled to the first arm and the second arm, respectively. The translating member is coupled between the proximal portion and the distal portion, and is configured to receive a drive force that causes the translating member to bias the distal portion to pivot relative to the proximal portion about the first axis.
