A surgical retrieval apparatus includes a housing having an elongated sleeve extending therefrom that, together, cooperate to define a lumen extending therethrough. A shaft having an end effector assembly disposed at a distal end thereof is selectively translatable between a first position, wherein the end effector assembly is disposed within the sleeve, and a second position, wherein the end effector assembly extends distally from the sleeve. A specimen retrieval bag is releasably coupled to the end effector assembly and is deployable to an extended position upon movement of the end effector assembly from the first to the second position.

1. A surgical retrieval apparatus, comprising: a housing defining a longitudinal axis and including an elongated sleeve extending distally therefrom, the housing and the elongated sleeve cooperating to define a lumen extending longitudinally therethrough;a shaft having an end effector assembly disposed at a distal end thereof, the shaft selectively translatable between a first position, wherein the end effector assembly is disposed within the elongated sleeve, and a second position, wherein the end effector assembly extends distally from the elongated sleeve;a specimen retrieval bag releasably coupled to the end effector assembly, the specimen retrieval bag deployable from an undeployed position to an extended position upon movement of the end effector assembly from the first position to the second position;a stop member disposed about the end effector assembly between the specimen retrieval bag and the shaft, the stop member configured to inhibit the specimen retrieval bag from returning within the lumen upon translation of the shaft from the second position back to the first position, the stop member defining a cinch cord aperture extending therethrough; anda cinch cord defining a first end, and second end, and a loop portion between the first and second ends, the loop portion positioned distally of the stop member and disposed about an open end of the specimen retrieval bag, the first and second ends extending proximally through the cinch cord aperture of the stop member, the first end knotted proximally adjacent the stop member to inhibit distal translation of the first end through the cinch cord aperture, the second end extending proximally through the shaft. 2. The surgical retrieval apparatus according to claim 1, further comprising a plunger disposed at a proximal end of the shaft and a pull-member releasably coupled to the plunger, the pull-member having the second end of the cinch cord coupled thereto, the pull-member configured, upon release from the plunger, for selective proximal translation relative to the plunger to cinch closed the specimen retrieval bag. 3. The surgical retrieval apparatus according to claim 1, further comprising a channel extending within the specimen retrieval bag and extending along at least a portion of the length of the specimen retrieval bag wherein the channel is configured to evacuate air from the specimen retrieval bag. 4. The surgical apparatus of claim 3, wherein the channel includes an open cell foam material positioned therein. 5. The surgical retrieval apparatus according to claim 1, further comprising a safety tab configured to engage both the housing and the shaft when the shaft is disposed in the first position to inhibit relative movement between the housing and the shaft. 6. The surgical retrieval apparatus according to claim 1, wherein the housing includes a pistol grip. 7. The surgical retrieval apparatus according to claim 1, wherein the specimen retrieval bag includes a strap coupled thereto that is secured to the stop member and the stop member includes a distally extending support to receive an end of the strap. 8. The surgical retrieval apparatus according to claim 1, further comprising a plunger positioned proximally of the shaft, wherein the plunger is configured to mate with the housing when the shaft is disposed in the second position. 9. The surgical retrieval apparatus according to claim 8, wherein the housing includes at least one detent and the plunger includes at least one flange, the at least one detent of the housing positioned adjacent to the at least one flange of the plunger when the shaft is disposed in the second position, the at least one detent and the at least one flange cooperable with one another to facilitate translation of the shaft from the second position back to the first position. 10. The surgical retrieval apparatus of claim 1, wherein the end effector assembly includes a pair of arms configured to receive the specimen retrieval bag thereon, the arms separable from the bag after closing the bag and withdrawal of the shaft, and the arms extend through an opening in the stop member. 11. The surgical retrieval apparatus according to claim 1, further comprising a plunger positioned proximally of the shaft and a pull-member releasably coupled to the plunger, wherein the plunger includes at least one resilient lock tab configured to releasably engage the pull-member thereon and a blade engaged thereto, the blade configured to facilitate cutting of the cinch cord to disengage the specimen retrieval bag from the shaft. 12. The surgical retrieval apparatus according to claim 1, wherein a diameter of the shaft is larger than a diameter of the opening to prevent proximal movement of the stop member over the shaft, and such that the stop member is positioned within the sleeve in an angled position and pivots when advanced from the shaft to prevent retraction into the shaft. 13. The surgical retrieval apparatus according to claim 1, wherein the shaft includes a shoulder defined on an outer periphery thereof, the shoulder configured to inhibit translation of the shaft proximally of the first position. 14. The surgical retrieval apparatus according to claim 1, wherein translation of the shaft from the second position back to the first position at least partially cinches closed the specimen retrieval bag. 15. The surgical retrieval apparatus according to claim 1, further comprising at least one O-ring disposed about the shaft, the at least one O-ring configured to frictionally retain the shaft in position relative to the housing and the elongated sleeve.
