    摘要： 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 an approximation mechanism including a rotatable knob, a screw having a helical channel and an anvil retainer. The helical channel includes a dwell portion for providing a tactile indication to a surgeon that the anvil retainer has been advanced to a position wherein the anvil assembly can be removed from the anvil retainer. A removable trocar for attachment to the anvil assembly is also disclosed which includes a rib positioned proximally of a mounting projection. The rib is positioned to align the mounting projection with associated engagement structure of the anvil assembly.

    摘要： 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.

    摘要： This application is directed to a surgical stapling device 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 handle portion includes a rotatable approximation knob for approximating the anvil and shell assemblies and a firing trigger for actuating a firing mechanism for ejecting staples positioned within the shell assembly. The firing trigger forms one link of a two bar linkage provided to actuate the firing mechanism. The anvil assembly includes a tiltable anvil which will tilt automatically after firing of the device and unapproximating the anvil and shell assemblies.

The head portion also includes a retractable trocar assembly which is slidably positioned within an anvil retainer and is automatically advanced and retracted upon attachment and detachment of the anvil assembly onto the anvil retainer. A lockout tube is provided and is positioned about an anvil retainer for releasably engaging an anvil assembly. The lockout tube prevents inadvertent detachment of the anvil assembly from the anvil retainer. The surgical stapling device also includes a firing lockout assembly which prevents actuation of the firing trigger until an anvil has been attached to the device and the anvil has been approximated. In one preferred embodiment, the firing lockout assembly includes a trigger lock and a safety bracket which prevents movement of the trigger lock from a locked to an unlocked position until an anvil has been attached to the device and approximated and returns the trigger lock to a locked position after the device has been fired. A tactile indication mechanism is also provided for notifying a surgeon that the device has been fired and for notifying a surgeon that the anvil head has been unapproximated a distance sufficient to permit the anvil head to tilt.

    摘要： There is disclosed a surgical instrument and loading unit for performing an anastomosis of first and second blood vessels. The surgical instrument includes a handle assembly and a body portion extending distally from the handle assembly. The detachable loading unit includes an anvil releasably engagable with a distal end of the body portion and having a plurality of fasteners disposed in channels about the circumference of a distal end of the anvil. A pusher is slidably mounted over the anvil such that distal movement of the pusher in response to actuation of the handle assembly cams the fasteners between the anvil and a distal end of the pusher to simultaneously crimp the fasteners about tissue. A method of performing an anastomosis is also disclosed and includes positioning a first vessel in the loading unit and partially inserting the first vessel through an opening in a second vessel. The surgical instrument is subsequently attached to the loading unit and the handle assembly is actuated to crimp fasteners about the first and second vessels to form an anastomosis.
