Abstract
A surgical instrument having a tactile and audible firing indicator is disclosed. The instrument has preferred features which include a tactile and audible indicator disposed in the handle housing for indicating to a user when the instrument has been properly and completely actuated.
Claims20
A surgical instrument, which comprises:
- a housing having a proximal end portion and a distal end portion;
- an elongated shaft extending from the housing distal end portion, the shaft having a proximal end portion and a distal end portion;
- a tool mechanism operatively positioned at the elongated shaft distal end portion and operable between a first position and a second position;
- an actuation mechanism disposed at least partially within the housing and operatively associated with the tool mechanism, the actuation mechanism being operable between a first position and a second position which defines substantially the full range of movement of the actuation mechanism, to provide corresponding movement of the tool mechanism between the first and second positions, respectively, thereof;
- and
- an indicator mechanism including a frangible member disposed in the housing and operatively associated with the actuation mechanism, the frangible member providing an audible and tactile indication upon substantially complete movement of the actuation mechanism from the first position to the second position.

A surgical instrument for applying at least one circular array of fasteners, comprising:
- a housing having a proximal end portion and a distal end portion;
- an elongated shaft extending from the housing distal end portion, the shaft having a proximal end portion and a distal end portion;
- a fastener carrying cartridge operatively positioned at the elongated shaft distal end portion;
- an anvil member operatively disposed adjacent the fastener carrying cartridge;
- an actuation mechanism disposed at least partially within the housing and operatively associated with the fastener carrying cartridge to deploy surgical fasteners therefrom;
- an indicator mechanism including a frangible member disposed in the housing, spaced from the fastener carrying cartridge and operatively associated with the actuation mechanism, the frangible member positioned to provide an audible and tactile indication upon substantially complete deployment of the surgical fasteners from the fastener carrying cartridge.

A circular anastomosis surgical stapling instrument for applying at least one circular array of staples, comprising:
- a housing having a proximal end portion and a distal end portion;
- an elongated shaft extending from the housing distal end portion, the shaft having a proximal end portion and a distal end portion;
- a staple cartridge operatively positioned at the elongated shaft distal end portion;
- an anvil member operatively disposed adjacent the staple cartridge;
- an actuation mechanism disposed at least partially within the housing and operatively associated with the staple cartridge to eject surgical staples therefrom;
- an indicator mechanism including a frangible member disposed in the housing and operatively associated with the actuation mechanism, the frangible member providing audible and tactile indications upon substantially complete ejection of the surgical staples.
