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, and a lockout tube.
