ROBOTICALLY-CONTROLLED CABLE-BASED SURGICAL END EFFECTORS
First Claim
Patent Images
1. A surgical tool for use with a robotic system that has 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 provide at least one rotary output motion to at least one rotatable body portion supported on the tool drive assembly, said surgical tool comprising:
- a surgical end effector comprising at least one movable component portion that is selectively movable between first and second positions relative to at least one other component portion thereof;
a cable drive assembly configured to apply at least one control motion to said at least one movable component portion of said surgical end effector; and
a tool mounting portion operably interfacing with said cable drive assembly and the at least one rotary body portion of the tool drive assembly of the robotic system such that application of at least one of the rotary output motions to the rotatable body portion causes said cable drive assembly to apply at least one of said control motions to said at least one movable component portion.

10. A surgical tool for use with a robotic system that has 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 provide at least one rotary output motion to at least one rotatable body portion supported on the tool drive assembly, said surgical tool comprising:
-
a surgical end effector comprising; a non-movable portion; a first movable component portion that is selectively movable between first and second positions relative to said non-movable portion; a second movable component portion that is selectively movable between third and fourth positions relative to said non-movable portion and wherein said surgical tool further comprises; an elongated shaft assembly operably coupled to said non-movable portion, said elongated shaft assembly at least partially operably supporting a cable drive assembly comprising; a first cable operably interfacing with said first movable component portion; and a second cable operably interfacing with said second movable component portion and wherein said surgical tool further comprises; a tool mounting portion operably coupled to said elongated shaft assembly, said tool mounting portion being configured to operably interface with the tool drive assembly when coupled thereto, said tool mounting portion comprising; a driven element rotatably supported on said tool mounting portion and configured for driving engagement with a corresponding one of said at least one rotatable body portions of the tool drive assembly to receive corresponding rotary output motions therefrom; and a cable drive transmission assembly operably interfacing with said driven element and being selectively shiftable in response to control signals from the control unit of the robotic system between a first actuation position wherein an application of one of said rotary output motions to the corresponding rotatable body portion causes said first cable to move said first movable component portion between said first and second positions and a second actuation position wherein said application of said one of said rotary output motions to the corresponding rotatable body portion causes said second cable to move said second movable component portion between said third and fourth positions. - View Dependent Claims (11, 12, 13, 14, 15)

16. A surgical tool for use with a robotic system that has 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 provide at least one rotary output motion to at least one rotatable body portion supported on the tool drive assembly, said surgical tool comprising:
-
a surgical end effector comprising; an elongated channel configured to support a surgical staple cartridge; an anvil movably supported relative to the elongated channel and being selectively movable between open and closed positions relative to said elongated channel; and a tissue cutting member selectively axially movable between unfired and fired positions and wherein said surgical tool further comprises; an elongated shaft assembly operably coupled to said elongated channel; a preclamping collar axially movable on said elongated shaft assembly for selective operable engagement with said anvil; a closure cable operably interfacing with said preclamping collar; and a firing cable operably interfacing with said tissue cutting member; a tool mounting portion operably coupled to said elongated shaft assembly, said tool mounting portion being configured to operably interface with the tool drive assembly when coupled thereto, said tool mounting portion comprising; a driven element rotatably supported on said tool mounting portion and configured for driving engagement with a corresponding one of said at least one rotatable body portions of the tool drive assembly to receive corresponding rotary output motions therefrom; and a cable drive transmission assembly operably interfacing with said driven element and being selectively shiftable in response to control signals from the control unit of the robotic system between a closure position wherein an application of one of said rotary output motions to the corresponding rotatable body portion in a first rotary direction causes said closure cable to move said preclamping collar into closing engagement with said anvil and a firing position wherein said application of said one of said rotary output motions in said first rotary direction to the corresponding rotatable body portion causes said firing cable to move said tissue cutting member from a starting position to an ending position within said elongated channel. - View Dependent Claims (17, 18, 19, 20)
