Motor driven surgical fastener device with switching system configured to prevent firing initiation until activated

A surgical instrument, comprising:

• a handle assembly;
• an end effector operably coupled to said handle assembly and comprising a distal end, wherein said end effector is movable between an open configuration and a closed configuration when a closing motion is applied thereto;
• a motor operably supported by said handle assembly;
• a firing member operably interfacing with said motor such that rotation of said motor in one direction causes said firing member to from a proximal starting position to a distal position in said end effector and rotation of said motor in an opposite direction causes said firing member to move from said distal position to said proximal starting position;
• a source of electrical power for powering said motor;
• a first switch operably communicating with said source of electrical power and said motor such that activation of said first switch causes an application of electrical power to said motor;
• and
• a second switch configured to prevent an application of electrical power from said source of electrical power to said motor unless said second switch has been activated.

A surgical instrument comprising:

• a handle assembly;
• a motor operably supported by said handle assembly;
• a source of electrical power operably supported by said handle assembly;
• an end effector coupled to said handle assembly, said end effector comprising:
• a surgical fastener cartridge operably supporting surgical fasteners therein;
• an anvil supported relative to said surgical fastener cartridge such that one of said surgical fastener cartridge and said anvil is selectively movable relative to the other of said surgical fastener cartridge and said anvil upon actuation of a closure system operably supported by said handle assembly;
• a firing member operably interfacing with said motor such that rotation of said motor in one direction causes said firing member to from a proximal starting position to a distal position in said end effector and rotation of said motor in an opposite direction causes said firing member to move from said distal position to said proximal starting position;
• a firing trigger movably supported on said handle assembly and communicating with said source of electrical power and said motor, such that upon actuation thereof in a first actuation direction permits an application of said electrical power to said motor to cause said motor to rotate in said first direction;
• and
• a second switch operably supported by said handle assembly and interfacing with said firing trigger to prevent actuation of said firing trigger unless said second trigger has been activated.
