A specimen removal apparatus includes a pouch assembly fabricated from a flexible membrane, a pouch support, a drawstring having a knot and forming a noose disposed circumferentially around a mouth of the pouch assembly, an endoscopic tubular portion, and a drive rod. The pouch assembly includes a plurality of circumferentially disposed guide members advantageously circumferentially spaced apart to define gaps therebetween. The guide members are disposed in a circumferential pathway proximal to the mouth of the pouch assembly. When the drawstring is pulled, the knot is stopped at an end of a guide member and the noose is closed, thereby closing the mouth of the pouch assembly. The pouch assembly is detachable from the apparatus.

What is claimed is: 1. A surgical apparatus for removing tissue from an interior portion of a body during a surgical procedure, comprising: an elongate tubular member having an open distal end and a bore defined therein; a pouch assembly movable between a proximal location at least partially within the tubular member and a distal location at least partially exterior to the tubular member, the pouch assembly including a support and a pouch removably attached to the support; the pouch having a first end movable between an open configuration and a closed configuration, and a closed second end; the pouch including a circumferential sleeve having a plurality of guide members, each guide member of the plurality of guide members having a passage and being configured to move toward adjacent guide members providing a variable space between guide members; a drive member disposed in the bore of the tubular member and attached to the support for moving the pouch assembly from an undeployed position to a deployed position; and a drawstring disposed in the circumferential sleeve, extending through at least one passage of the guide members, and forming a loop having a diameter corresponding with the diameter of the first end of the pouch. 2. The apparatus of claim 1, wherein the pouch has at least a first sac with a first diameter and a second sac with a second diameter different than the first. 3. The apparatus of claim 2, wherein the first sac has an open distal end in communication with an open proximal end of the second sac. 4. The apparatus of claim 3, further comprising a reinforced region overlapping a distal end of the first sac and a proximal end of the second sac. 5. The apparatus of claim 3, wherein the first diameter is greater than the second diameter. 6. The apparatus of claim 5, wherein the second sac has a closed distal end. 7. The apparatus of claim 5, further comprising a third sac having an open proximal end in communication with an open distal end of the second sac. 8. The apparatus of claim 7, wherein the third sac has a closed distal end. 9. The apparatus of claim 1, wherein the support comprises a spring biased toward a deployed position. 10. The apparatus of claim 1, wherein the support comprises a pair of flexible strips, each of the flexible strips having a first end attached to the drive member. 11. The apparatus of claim 10, wherein each of the flexible strips has a second end engaged by a joiner. 12. The apparatus of claim 1, further comprising a locking tab having a locking position in engagement with the drive member and a releasing position disengaged from the drive member. 13. The apparatus of claim 12, further comprising a handle at a distal end of the tubular member, the handle slidably supporting the locking tab. 14. The apparatus of claim 1, further comprising an actuator attached to the drawstring for moving the first end of the pouch. 15. The apparatus of claim 1, wherein the pouch comprises a sheet of substantially transparent material. 16. The apparatus of claim 1, wherein the circumferential sleeve comprises a lower circumferential sleeve for receiving the drawstring. 17. The apparatus of claim 16, wherein the pouch has an upper circumferential sleeve for receiving the support. 18. The apparatus of claim 17, wherein the pouch has a weakened portion disposed between the upper and lower circumferential sleeves. 19. The apparatus of claim 16, wherein the guide members are spaced from one another within the lower circumferential sleeve. 20. A surgical apparatus for removing tissue from an interior portion of a body during a surgical procedure, comprising: an elongate tubular member having an open distal end and a bore defined therein; a pouch assembly movable between a proximal location at least partially within the tubular member and a distal location at least partially exterior to the tubular member, the pouch assembly including a support and a pouch removably attached to the support; the pouch having a first end movable between an open configuration and a closed configuration, and a closed second end; the pouch including a circumferential sleeve having a plurality of guide members, each guide member of the plurality of guide members having a passage; a drive member disposed in the bore of the tubular member and attached to the support for moving the pouch assembly from an undeployed position to a deployed position; and a drawstring disposed through each of the passages of the guide members in the circumferential sleeve and forming a loop, the guide members configured to reduce frictional force between the drawstring and circumferential sleeve.
