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.

Claims (16)

1. A surgical stapling device, comprising:

an end effector including an anvil assembly and a cartridge assembly pivotally coupled to one another, the anvil assembly and the cartridge assembly being relatively movable such that the end effector is movable between an open position and a clamped position; and

a specimen bag including a body and a mouth defining an open end, the mouth attached to the anvil assembly and the cartridge assembly such that movement of the end effector to the open position moves the mouth of the specimen bag to an open position.

2. The surgical stapling device according to claim 1 , wherein the mouth of the specimen bag includes a drawstring housing having a drawstring therein.

3. A method, comprising:

advancing a surgical stapling device including an anvil assembly and a cartridge assembly into a body cavity adjacent tissue to be removed from a patient's body;

placing the tissue to be removed from the patient's body into a specimen bag having a mouth attached to the anvil assembly and the cartridge assembly;

closing the anvil assembly and the cartridge assembly on the tissue; and

firing the surgical stapling device to separate a tissue specimen from the tissue.

4. The method of claim 3 , further comprising grasping the tissue specimen to pull the tissue specimen deeper into the specimen bag.

5. The method of claim 4 , wherein grasping the tissue specimen to pull the tissue specimen deeper into the specimen bag occurs after firing the surgical stapling device.

6. The method of claim 3 , further comprising closing the mouth of the specimen bag after firing the surgical stapling device.

7. The method of claim 6 , wherein closing the mouth of the specimen bag occurs by proximally pulling a drawstring encompassing the mouth of the specimen bag.

8. The method of claim 7 , wherein proximally pulling the drawstring encompassing the mouth of the specimen bag further includes detaching the mouth of the specimen bag from the anvil assembly and the cartridge assembly.

9. The method of claim 8 , wherein proximally pulling the drawstring encompassing the mouth of the specimen bag further includes detaching the specimen hag from an adapter assembly of the surgical stapling device.

10. The method of claim 8 , wherein proximally pulling the drawstring encompassing the mouth of the specimen bag includes removing the specimen bag from the patient's body.
