Surgical devices and methods are provided that utilize an end effector biased to a closed position when an actuator of the device is biased in an uncompressed configuration. End effectors according to the present disclosure can include first and second jaws that can be moved from the biased closed position to an open position by compressing the actuator from the uncompressed configuration and towards a compressed configuration. Various force assemblies and related components are provided that allow the device to achieve two end effector actuation profiles: (1) moving from a closed position and to an open position； and (2) moving from a closed position, to an open position, and back to the closed position. Various structures and methods for operating such devices during a surgical procedure are also provided.
