Abstract
A system for closing an opening in tissue may include an end effector that holds a staple, where the staple is plastically deformed to a splayed configuration for engaging tissue, then plastically deformed to a closed condition for closing the opening. The system may include one or more butterfly members configured to register the opening to the end effector.
Claims44
A system for closing an opening in tissue, comprising:
- an end effector having a longitudinal axis, said end effector including at least one paddle;
- and
- a staple having a plurality of tines, wherein said staple is held by said end effector and wherein at least part of at least one said paddle is movable relative to said staple.
A tool for closing an opening in tissue, comprising:
- a staple including a plurality of tines, said staple plastically-deformable to a splayed configuration and a closed configuration;
- and
- an end effector including a driver, wherein said driver is movable to exert a force in the distal direction on a proximal surface of said staple to splay said staple to said splayed configuration and close said staple to said closed configuration.
A method for closing an opening in tissue, comprising:
- providing a staple having a plurality of tines and a longitudinal centerline, wherein said staple is a substantially continuous solid;
- plastically deforming said staple to a splayed configuration;
- penetrating at least one said tine into tissue in proximity to the opening;
- and
- plastically deforming said staple to a closed configuration.
A tool for closing an opening in tissue, comprising:
- a housing;
- a staple held by said housing;
- and
- at least one butterfly member extending distally from said housing, each said butterfly member including a first element and a second element connected to one another at the distal ends thereof;
- wherein at least one said element transmits both compressive and tensile force;
- and wherein at least one said butterfly member is movable between a collapsed configuration and an expanded configuration.
A method for closing an opening in tissue, comprising:
- providing a staple having a plurality of tines;
- plastically deforming said staple to a splayed configuration, wherein said deforming results from application of force in the distal direction against a proximal surface of said staple;
- penetrating at least one said tine into tissue in proximity to the opening;
- and
- plastically deforming said staple from said splayed configuration to a closed configuration, wherein said deforming results from application of force in the distal direction against a proximal surface of said staple.
