Surgical instrument with indicator
First Claim
1. A method of performing a surgical task, the method comprising:
- providing a surgical instrument comprising;
a handle assembly;
an elongated body portion extending distally from the handle assembly;
first and second jaw members disposed adjacent a distal portion of the elongated body portion, the first jaw member supporting an anvil assembly and the second jaw member supporting a shell assembly, the shell assembly including a circular array of staples; and
an indicator disposed in mechanical cooperation with the handle assembly;
moving the first jaw member toward the second jaw member to move the indicator from a first position toward a second position; and
firing the surgical instrument, while maintaining the first jaw member fixed in relation to the second jaw member, to eject the circular array of staples from the shell assembly and to move the indicator from the second position toward a third position.

Abstract
A surgical stapling instrument including a handle assembly, an elongated body portion extending distally from the handle assembly, a head portion and an indicator. A firing trigger is movable between first and second positions. The head portion includes an anvil assembly and a shell assembly. The anvil assembly is movable in relation to the shell assembly between spaced and approximated positions. The indicator is disposed in mechanical cooperation with the handle assembly and is movable between a first position and a second position in response to movement of the anvil assembly towards its approximated position. The indicator is movable between the second position and a third position in response to firing of the instrument.

7. A method of surgical joining tissue, the method comprising:
-
providing a surgical instrument comprising; a handle assembly including a movable handle; an elongated body portion extending distally from the handle assembly; first and second jaw members disposed adjacent a distal portion of the elongated body portion, the first jaw member being movable with respect to the second jaw member between spaced and approximated position, the first jaw member supporting an anvil assembly and the second jaw member supporting a shell assembly, the shell assembly including a circular array of staples; and an indicator disposed in mechanical cooperation with the handle assembly; actuating the movable handle to a first predetermined position to move the first jaw member in relation to the second jaw member from the spaced position to the approximated position to move the indicator from a first position to a second position; and actuating the movable handle from the first predetermined position to a second predetermined position to eject the circular array of staples from the shell assembly and to move the indicator from the second position to a third position. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method of surgical joining tissue, the method comprising:
-
providing a surgical instrument comprising; a handle assembly including a movable handle and a pawl and wherein the movable handle is configured to contact the pawl when the movable handle is moved to the second predetermined position; an elongated body portion extending distally from the handle assembly; first and second jaw members disposed adjacent a distal portion of the elongated body portion, the first jaw member being movable with respect to the second jaw member between spaced and approximated position; an indicator disposed in mechanical cooperation with the handle assembly; and actuating the movable handle to a first predetermined position such that the indicator moves from a first position to a second position; and actuating the movable handle from the first predetermined position to a second predetermined position such that the indicator moves from the second position to a third position, the surgical instrument further comprising a slide member operatively associated with the indicator, the pawl including an engagement surface engageable with the slide member to effect further proximal movement of the slide member to move the indicator to the third position.

19. A method of surgical joining tissue, the method comprising:
-
providing a surgical instrument comprising; a handle assembly including a movable handle and a pawl and wherein the movable handle is configured to contact the pawl when the movable handle is moved to the second predetermined position; an elongated body portion extending distally from the handle assembly; first and second jaw members disposed adjacent a distal portion of the elongated body portion, the first jaw member being movable with respect to the second jaw member between spaced and approximated position; an indicator disposed in mechanical cooperation with the handle assembly; and actuating the movable handle to a first predetermined position such that the indicator moves from a first position to a second position; and actuating the movable handle from the first predetermined position to a second predetermined position such that the indicator moves from the second position to a third position, the surgical instrument further comprising a slide member operatively associated with the indicator, the pawl having an engagement surface engageable with the slide member to retract the slide member.

20. A method of surgical joining tissue, the method comprising:
-
providing a surgical instrument comprising; a handle assembly including a movable handle; an elongated body portion extending distally from the handle assembly; first and second jaw members disposed adjacent a distal portion of the elongated body portion, the first jaw member being movable with respect to the second jaw member between spaced and approximated position; an indicator disposed in mechanical cooperation with the handle assembly; and actuating the movable handle to a first predetermined position such that the indicator moves from a first position to a second position; and actuating the movable handle from the first predetermined position to a second predetermined position such that the indicator moves from the second position to a third position, the surgical instrument further comprising a slide member operatively associated with the indicator and an approximation mechanism for moving the first jaw member between spaced and approximated positions, the approximation mechanism including a screw stop engageable with the slide member to move the slide member proximally upon retraction of the screw stop to move the indicator to the second position, wherein the handle assembly includes a pawl and the movable handle is configured to contact the pawl when the movable handle has moved to its second predetermined position, the pawl having an engagement surface engageable with the slide member to move the slide member farther proximally to move the indicator to the third position.
