Surgical tool with manual control of end effector jaws
A surgical tool of a robotic surgical device is provided that is configured to be removably and replaceably attached to an electromechanical arm of a surgical robotic system that is capable of supplying electrical power to the surgical tool when the tool is attached to the arm. The tool has an elongate shaft with an end effector having opposed jaws movable between open and closed positions. The tool also has a member configured to move distally and proximally within at least a portion of the end effector to open and close the jaws. An actuator disposed on the shaft is configured to be manually moved from a first position to a second position to cause the member to move proximally to thereby open the jaws when the surgical tool is in a mode in which it is not deriving electrical power from the surgical robotic system.

an end effector, comprising:
a first jaw;
a second jaw rotatable relative to said first jaw between an open position and a closed position; and
a staple cartridge comprising staples removably stored therein;
a closure driver comprising a first cam configured to engage said first jaw and a second cam configured to engage said second jaw, wherein said closure driver is driveable by the rotary motion of said motor-driven rotary driver to close said second jaw; and
a manually-driven actuator that does not require the rotary motion of said motor-driven rotary driver to open and close said second jaw such that said manually-driven actuator is coupled to said closure driver and actuatable to selectively decouple said closure driver and said motor-driven rotary driver, wherein said manually-driven actuator is operable to open said second jaw without having to de-couple said housing from the robotic surgical system, and wherein said manually-driven actuator comprises a manually-engageable grip surface configured to facilitate manual movement of and coupled to said manually-driven actuator between a first position corresponding to the closed position of said second jaw and a second position corresponding to the open position of said second jaw, wherein said manually-engageable grip surface is movable in a first direction to move said manually-driven actuator toward said first position thereby moving said closure driver to move said second jaw toward said closed position, and wherein said manually-engageable grip surface is movable in a second direction opposite the first direction to move said manually-driven actuator toward said second position thereby moving said closure driver to move said second jaw toward said open position.
