Clip applier comprising a motor controller

A surgical device for clipping tissue, comprising

• a housing comprising a motor;
• a shaft extending from said housing;
• a jaw actuator operably responsive to said motor, wherein said jaw actuator is configured to translate between a proximal position and a distal position;
• a clip magazine comprising a plurality of clips;
• a reciprocating feeder drive operably responsive to said motor;
• an end effector extending from said shaft, comprising:
• a first jaw;
• and
• a second jaw, wherein said first jaw and said second jaw are movable relative to each other between an open configuration and a closed configuration when said jaw actuator is moved between said proximal position and said distal position;
• and
• a motor controller configured to:
• advance a said clip from said clip magazine into said end effector by way of said reciprocating feeder drive while actuating said jaw actuator to move said first jaw and said second jaw toward said open configuration in response to a first user input in a firing operating mode;
• and
• actuate said jaw actuator to move said first jaw and said second jaw toward said closed configuration without advancing a said clip into said end effector in response to a second user input in a manipulation operating mode.

• a clip magazine comprising a plurality of clips;
• an end effector movable between an open position and a closed position;
• a jaw actuator operably responsive to a first rotatable input, wherein said jaw actuator is configured to move said end effector between said open position and said closed position;
• a reciprocating feeder drive operably responsive to a second rotatable input;
• and
• a controller configured to:
• advance a said clip from said clip magazine into said end effector by way of said reciprocating feeder drive when said end effector is in said open position;
• and
• actuate said jaw actuator to move said end effector toward said closed position without advancing a said clip into said end effector.

A surgical device for clipping tissue, the surgical device comprising:

• an end effector, comprising:
• a first jaw;
• and
• a second jaw, wherein said first jaw and said second jaw are configurable relative to each other in an open configuration and a closed configuration;
• a jaw actuator operably responsive to a motorized system, wherein said jaw actuator is configured to transition said first jaw and said second jaw between said open configuration and said closed configuration;
• a reciprocating feeder drive operably responsive to the motorized system;
• and
• a motor controller, configured to:
• control said reciprocating feeder drive independent of said jaw actuator;
• advance a clip from a clip magazine into said end effector by way of said reciprocating feeder drive without actuating said jaw actuator;
• and
• actuate said jaw actuator without advancing a said clip into said end effector.

A surgical device usable for clipping tissue, the surgical device comprising:

• an end effector, comprising:
• a first jaw;
• and
• a second jaw, wherein said first jaw and said second jaw are transitionable between an open configuration and a closed configuration;
• a jaw actuator operably responsive to a motorized system, wherein said jaw actuator is configured to move between a proximal position and a distal position, and wherein said first jaw and said second jaw are configured to transition between said open configuration and said closed configuration based on movement of said jaw actuator;
• a reciprocating feeder drive operably responsive to the motorized system;
• and
• a motor controller, configured to:
• advance a clip from a clip magazine into said end effector by way of said reciprocating feeder drive while actuating said jaw actuator to move said first jaw and said second jaw toward said open configuration, based on a first user input in a firing operating mode;
• and
• actuate said jaw actuator to move said first jaw and said second jaw toward said closed configuration without advancing a clip from the clip magazine into said end effector, based on a second user input in a manipulation operating mode.
