More Information
Summary:A robotic surgical tool includes a handle and an instrument driver releasably coupled to the handle, an elongate shaft extendable through the handle and the instrument driver, and a decoupler interposing the handle and the instrument driver. The decoupler includes an insertion assembly actuatable to move the shaft, an insertion transmission gear driven by the insertion assembly, and a dwell slip clutch including an input clutch gear and an output clutch gear, the dwell slip clutch being movable between collapsed and expanded states. A lockout ring extends about the decoupler housing, and a latch ring extends about the decoupler housing and is axially offset from the lockout ring. Fully retracting the shaft moves the dwell slip clutch to the compressed state to drive the output clutch gear against the lockout ring, thereby enabling latch ring to move to an unlocked position that separates the handle from the instrument driver.
