Surgical stapling device with visual indicator
First Claim
1. A surgical stapling device comprising:
- a handle assembly including a body having a top surface and a firing trigger;
a body portion extending distally from the handle assembly;
a head portion including an anvil assembly and a shell assembly, the anvil assembly being movable in relation to the shell assembly between spaced and approximated positions; and
an indicator positioned on the handle assembly and having a bulbous shape, the indicator being movable from a first position to a second position in response to movement of the anvil assembly and the shell assembly to the approximated position to provide a visual indication to a surgeon that the head portion is in the approximated position, the bulbous indicator extending outwardly from a top surface of the body such that the bulbous indicator is viewable from above and opposite sides of the device.

Abstract
A surgical stapling device is disclosed for performing circular anastomoses. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. The head portion includes an anvil assembly including a tiltable anvil which will tilt automatically after the device has been fired and unapproximated. The tiltable anvil provides a reduced anvil profile to reduce trauma during removal of the device after the anastomoses procedure has been performed. The stapling device includes a bulbous indicator which preferably extends above a top surface of the handle assembly of the device. The indicator includes indicia to identify to a surgeon that the device has been approximated and is in a fire-ready position. Preferably, the indicator includes a cover which is formed of a magnification material to prominently display the indicia. The anvil assembly of the stapling device preferably includes a retainer clip positioned on the anvil head. The retainer clip preferably includes at least one resilient arm which is positioned to engage a cutting ring during unapproximation of the stapling device.

8. A surgical stapling device comprising:
-
a handle assembly including a firing trigger; a body portion extending distally from the handle assembly; a head portion including an anvil assembly and a shell assembly, the anvil assembly being movable in relation to the shell assembly between spaced and approximated positions; an indicator positioned on the handle assembly and having a bulbous shape, the indicator being movable from a first position to a second position in response to movement of the anvil assembly and the shell assembly to the approximated position to provide a visual indication to a surgeon that the head portion is in the approximated position; an approximation mechanism positioned within the handle assembly and extending at least partially through the body portion, the approximation mechanism having a distal end adapted to engage the anvil assembly, the approximation mechanism being movable within the device to move the anvil assembly between the spaced position and the approximated position in relation to the shell assembly; wherein the approximation mechanism is operably associated with the indicator such that movement of the approximation mechanism effects movement of the indicator; and a slide member operably associated with the indicator and movable within the handle assembly, the slide member being movable from an advanced position to a retracted position to move the indicator from the first position to the second position; wherein the slide member is urged to its advanced position by a biasing member.

9. A surgical stapling device comprising:
-
a handle assembly including a firing trigger; a body portion extending distally from the handle assembly; a head portion including an anvil assembly and a shell assembly, the anvil assembly being movable in relation to the shell assembly between spaced and approximated positions; an indicator positioned on the handle assembly and having a bulbous shape, the indicator being movable from a first position to a second position in response to movement of the anvil assembly and the shell assembly to the approximated position to provide a visual indication to a surgeon that the head portion is in the approximated position; an approximation mechanism positioned within the handle assembly and extending at least partially through the body portion, the approximation mechanism having a distal end adapted to engage the anvil assembly, the approximation mechanism being movable within the device to move the anvil assembly between the spaced position and the approximated position in relation to the shell assembly; wherein the approximation mechanism is operably associated with the indicator such that movement of the approximation mechanism effects movement of the indicator; a slide member operably associated with the indicator and movable within the handle assembly, the slide member being movable from an advanced position to a retracted position to move the indicator from the first position to the second position; and wherein the approximation mechanism includes a screw member which is linearly movable within the handle assembly, the screw member having an abutment member supported thereon, the abutment member being movable with the screw member into engagement with the slide member to move the slide member from its advanced position to its retracted position to move the indicator from its first position to its second position. - View Dependent Claims (10, 11, 12)
