Abstract
Surgical instrument systems comprising lockouts are disclosed. The systems comprise a firing member, a staple cartridge assembly, and a lockout member. The lockout member, movable between an unlocked position and a locked position, is configured to prevent the firing member from being advanced through the staple cartridge assembly when the lockout member is in its locked position.
Claims18
A surgical end effector system, comprising:
- a firing member;
- a staple cartridge assembly configured to be installed into said end effector system, said staple cartridge assembly comprising:
- a cartridge body;
- a plurality of staples removably stored within said cartridge body;
- a sled comprising a magnet, wherein said firing member is configured to move said sled between an unfired position and a partially-fired position during a staple firing stroke;
- an installed, ready-to-fire configuration wherein said sled is in said unfired position;
- and
- a false configuration;
- and
- a lockout member, comprising:
- a locked position, wherein said lockout member is configured to prevent said firing member from firing said staples from said staple cartridge assembly when said lockout member is in said locked position;
- and
- an unlocked position, wherein said lockout member is configured to permit said firing member to fire said staples from said staple cartridge assembly when said lockout member is in said unlocked position;
- wherein said magnet is configured to levitate said lockout member into said unlocked position when said staple cartridge assembly is in said installed, ready-to-fire configuration, and wherein said lockout member is biased into said locked position when said staple cartridge assembly is in said false configuration.

An end effector, comprising:
- a firing member movable between a proximal position and a distal position;
- a staple cartridge assembly removably positionable in said end effector, wherein said staple cartridge assembly comprises:
- a cartridge body;
- a plurality of staples removably positioned within said cartridge body;
- and
- a sled comprising a magnet, wherein said firing member is configured to move said sled from a starting position toward said distal position during a staple firing stroke;
- and
- a lockout system, configurable between:
- a locked configuration, wherein said lockout system is configured to prevent said firing member from moving toward said distal position;
- and
- an unlocked configuration, wherein said lockout system is configured to permit said firing member to move toward said distal position;
- wherein said magnet is configured to move said lockout system toward said unlocked configuration when said sled is in said starting position, and wherein said lockout system is moved into said locked configuration once said firing member has moved to said proximal position after moving said sled toward said distal position.

An end effector, comprising:
- a firing member;
- a staple cartridge assembly removably positionable in said end effector, wherein said staple cartridge assembly comprises:
- a cartridge body;
- a plurality of staples removably positioned within said cartridge body;
- and
- a sled comprising a magnet, wherein said firing member is configured to move said sled from a proximal position toward a distal position during a staple firing stroke;
- and
- a blocking member movable between:
- a blocked position, wherein said blocking member is configured to block said firing member from moving toward said distal position;
- and
- an unblocked position, wherein said blocking member is configured to permit said firing member to move toward said distal position;
- wherein said magnet is configured to move said blocking member toward said unblocked position when said sled is in said proximal position, and wherein said blocking member is configured move toward said blocked position as said firing member moves said sled toward said distal position.
