Zusammenfassung:A surgical instrument (10) includes an end effector assembly (100) and a deployment mechanism (80) for deploying a proximal hub associated with an energizable member (200) between proximal and distal positions. The deployment mechanism (80) includes a rotatable shaft (88), a cord (96) including a proximal end engaged to the rotatable shaft (88) and a distal end engaged to the proximal hub, a biasing member (94) positioned to bias the proximal hub towards the distal position, and a gear assembly (84) operably coupled to the rotatable shaft (88). The gear assembly (84) is configured to move the proximal hub from the distal position to the proximal position against the bias of the biasing member (94) by rotating the rotatable shaft (88) relative to the cord (96) to at least partially wind-up the cord (96) about the rotatable shaft (88).
