Abstract
A surgical stapling device includes an end effector and a handle assembly operably coupled to the end effector. The end effector includes an anvil assembly and a cartridge assembly. The surgical stapling device also includes a specimen bag adhered to both the anvil assembly and the elongated support channel of the cartridge assembly. The specimen bag includes a drawstring within a drawstring housing. Once the surgical stapling device is inserted into a patient's body and the anvil assembly and the cartridge assembly are open, a tissue specimen is placed into the specimen bag. The anvil assembly and the cartridge assembly are then closed on the tissue specimen and the surgical stapling device is fired. The specimen bag then separates from the surgical stapling device and both the surgical stapling device and the specimen bag are removed from the patient.
