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