Abstract
A surgical stapling instrument including a latch for securing first and second jaw members together, a cutting member which can be advanced and/or retracted relative to first and second jaw members, and, in addition, a lock which can prevent, or at least inhibit, the cutting member from being moved, or at least advanced, relative to the first and second jaw members before the latch has been closed. In at least one embodiment, the latch can be configured to engage the lock as the latch is moved from a fully open position to a fully closed position and operably disengage the lock from the cutting member.
Claims43
A surgical stapler, comprising:
- a first handle portion including a staple cartridge channel configured to receive a staple cartridge;
- a second handle portion including an anvil;
- a first drive slot;
- a second drive slot, wherein at least one of said first and second drive slots defines a predetermined path;
- a drive member;
- an actuator operably engaged with said drive member, wherein said actuator is selectively movable into said first drive slot and said second drive slot, and wherein said actuator is configured to move said drive member along said predetermined path;
- an actuator lock selectively engageable with said actuator;
- and
- a latch rotatably coupled to one of said first handle portion and said second handle portion, wherein said latch is movable between an open position and a closed position, wherein said latch is configured to engage the other of said first handle portion and said second handle portion and move said anvil into position relative to said staple cartridge channel, and wherein said latch is configured to engage said actuator lock when said latch is moved into said closed position to disengage said actuator lock from said actuator.
