Abstract

In one aspect, a surgical retractor having sliders configured to have tissue engaging members connected thereto and slider drives including operating members. The operating members are rotatable to cause the slider drives to shift the sliders relative to one another. The surgical retractor includes a coupler having a coupling configuration wherein the coupler connects the slider drives and rotation of one of the operating members causes movement of the sliders. The coupler also has a decoupling configuration wherein the coupler disconnects the slider drives and rotation of the one operating member causes movement of fewer sliders than the sliders that are moved with the coupler in the coupling configuration. The retractor has an actuator connected to the coupler and movable between a dependent slider movement position and an independent slider movement position to shift the coupler between the coupling configuration and the decoupling configuration.
