Robotically powered surgical device with manually-actuatable reversing system
First Claim
1. A surgical tool for use with a robotic system that includes a tool drive assembly that includes a plurality of rotary output members that are selectively rotatable upon applications of inputs from an operator to a control unit of the robotic system, wherein said surgical tool comprises:
- a surgical end effector comprising;
a first jaw and a second jaw; and
a firing member axially movable between a starting position and an ending position within said first and second jaws and wherein said surgical tool further comprises;
an elongate shaft assembly operably coupled to said surgical end effector and comprising a firing shaft operably interfacing with said firing member to apply firing motions thereto;
a tool mounting portion operably coupled to said elongate shaft assembly and configured for removable operable attachment to the tool drive assembly of the robotic system, wherein said tool mounting portion comprises;
a firing drive system, comprising;
a first rotary drive assembly configured for operable rotary engagement with a corresponding one of the rotary output members when said tool mounting portion is operably attached to the tool drive assembly of the robotic system;
a second rotary drive assembly in operable engagement with said firing shaft and movable between a first engaged position, wherein said second rotary drive assembly is in operable engagement with said first rotary drive assembly such that rotation of the corresponding one of the rotary output members in a first actuation direction causes said second rotary drive assembly to apply rotary firing motions to said firing shaft in a first rotary direction, and a disengaged position, wherein said second rotary drive assembly is disengaged from said first rotary drive assembly while said first rotary drive assembly remains in operable rotary engagement with the corresponding one of the rotary output member; and
a manually-actuatable control system configured to, upon actuation, move said second rotary drive assembly out of operable engagement with said first rotary drive assembly and apply additional rotary firing motions to said firing shaft while said first rotary drive assembly remains in operable rotary engagement with the corresponding one of the rotary output members.

Abstract
A surgical tool for use with a robotic system that includes a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to robotically-generate output motions. A drive system is configured to interface with a corresponding portion of the tool drive assembly for receiving the robotically-generated output motions and applying the output motions to a drive shaft assembly which is configured to apply control motions to a surgical end effector operably coupled thereto. A manually-actuatable control system operably interfaces with the drive shaft assembly to facilitate the selective application of manually-generated control motions to the drive shaft assembly.

15. A surgical tool for use with a robotic system that includes a tool drive assembly that includes a rotary output member that is selectively rotatable upon application of inputs from an operator to a control unit of the robotic system, wherein said surgical tool comprises:
-
a surgical end effector comprising; a first jaw and a second jaw, wherein one of said first and second jaws is movable relative to the other of said first and second jaws between open and closed positions upon application of jaw control motions thereto; and a firing member axially movable between a starting position and an ending position within said first and second jaws and wherein said surgical tool further comprises; an elongate shaft assembly operably coupled to said surgical end effector and comprising a firing shaft operably interfacing with said firing member to apply firing motions thereto; a tool mounting portion operably coupled to the elongate shaft assembly and configured for removable operable attachment to the tool drive assembly of the robotic system, wherein said tool mounting portion comprises; a firing drive system in operable engagement with the rotary output member and being configurable between an actuatable configuration in which actuation of the rotary output member applies rotary control motions thereto which causes said firing drive system to apply rotary firing motions to said firing shaft with a first portion of the firing drive system and an unactuatable configuration in which a second portion of said firing drive system remains in operable engagement with the rotary output member and the first portion of said firing drive system is disengaged from said second portion; a manually-actuatable control system configured to, upon actuation, arrange said firing drive system into said unactuatable configuration and apply additional rotary firing motions to said firing shaft with said first portion of said firing drive system; and a closure system configured to generate said jaw control motions, wherein said closure system is configured to apply axial closure motions to a closure portion of said elongate shaft assembly to cause said closure portion to apply said jaw control motions to at least one of said first and second jaws, and wherein said closure system comprises; a closure solenoid in operable communication with the control unit of the robotic system to receive control signals therefrom; and an axially movable closure assembly in operable engagement with said closure solenoid and at least one of said first and second jaws.
