A stapler is disclosed that includes a mechanism for sensing whether the stapler is loaded with a fired cartridge housing and for preventing the stapler from being closed or fired when loaded with the fired cartridge. The mechanism also prevents the stapler from firing or clamping on tissue when the stapler is not loaded with a staple cartridge.
A surgical stapler comprising: an anvil frame having proximal and distal ends, and a pair of lateral side portions each being elongate in a longitudinal direction and spaced to define a channel therebetween, said anvil frame having a handle portion generally adjacent said proximal end and having fir
A surgical stapler comprising: an anvil frame having proximal and distal ends, and a pair of lateral side portions each being elongate in a longitudinal direction and spaced to define a channel therebetween, said anvil frame having a handle portion generally adjacent said proximal end and having first and second ends, and a jaw portion having anvil surfaces generally adjacent said distal end and positioned in a plane generally perpendicular to said longitudinal direction, and an elongate manually movable lever part having first and second ends, said lever part having pivot means at said second end adapted for affording relative pivotal movement of said lever part and said anvil frame between a release position with said first end of said lever part being spaced from said first end of said handle portion and an actuation position with said lever part and said handle portion in closely spaced relationship; biasing means for biasing said lever part toward said release position; a cartridge assembly having proximal and distal ends and being mounted in said channel between said lateral side portions for longitudinal movement relative to said anvil frame, said cartridge assembly including, a cartridge transporting member having first and second side portions each being elongate in said longitudinal direction and being spaced to define a ram channel therebetween, said first and second side portions having surfaces defining a cartridge groove generally adjacent said distal end of said cartridge assembly, said cartridge groove surfaces being adapted to releasably receive a cartridge housing containing a plurality of staples disposed in at least one row positioned in opposition to said anvil surfaces, and pusher means for pressing said staples within said cartridge housing against said anvil surfaces to engage and close the staples in tissue between the cartridge housing and the anvil surfaces, said pusher means mounted for movement relative to the cartridge housing between a pre-fired and a fired position; means mounting said cartridge assembly for longitudinal movement relative to said anvil frame between a closed position with said cartridge housing and said anvil surfaces in closely spaced relationship, and an open position with said cartridge housing and said anvil surfaces spaced farther from each other than in said closed position; an elongate ram mounted in said ram channel between said first and second side portions for longitudinal movement relative to said cartridge transporting member and said anvil frame, said ram engaging said pusher means to move said pusher means from said prefired position to said fired position when said cartridge housing and said anvil surfaces are in closely spaced relationship; actuation means for initially moving said cartridge assembly from said open position to said closed position in response to movement of said lever part from said release position to said actuation position and for subsequently moving said ram distally relative to said cartridge transporting member by again moving said lever part from said release position to said actuation position; means for biasing said cartridge assembly from said closed position to said open position; and means for preventing said cartridge assembly from moving from said open position to said closed position when the stapler is loaded with a cartridge housing having the pusher means disposed in a fired position, said preventing means including a safety aperture defining an opening in the surface of the anvil frame and a locking pin mounted in the safety aperture for movement between a first position to afford free movement of the cartridge assembly between said open position and said closed position, and a second blocking position to prevent such movement.
