A surgical retrieval apparatus includes a handle including an elongated sleeve extending therefrom that, together cooperate to define a lumen therethrough. A shaft having an end effector assembly disposed at a distal end thereof and a plunger disposed at a proximal end thereof is selectively translatable between a first position and a second position, wherein the end effector assembly extends from the sleeve. An articulation mechanism is configured to articulate the end effector assembly relative to the shaft. A specimen retrieval bag is coupled to the end effector assembly and is deployable to an extended position upon movement of the end effector assembly to the second position.

1. A surgical retrieval apparatus, comprising: a handle defining a longitudinal axis and including an elongated sleeve extending distally therefrom, the handle and the elongated sleeve cooperating to define a lumen extending longitudinally therethrough, the handle defining an articulation track on an inner surface thereof, wherein the articulation track defines a helical configuration;a shaft having an end effector assembly disposed at a distal end thereof and a plunger disposed at a proximal end thereof, the shaft selectively translatable between a first position, and a second position, wherein the end effector assembly extends distally from the elongated sleeve;an articulation mechanism configured to articulate the end effector assembly relative to the shaft between an aligned position, wherein the end effector assembly is longitudinally aligned relative to the longitudinal axis, and an articulated position, wherein the end effector assembly is disposed at an oblique angle relative to the longitudinal axis, the articulation mechanism including an articulation post configured to move along the articulation track upon rotation of the handle about the longitudinal axis and relative to the shaft to articulate the end effector assembly between the aligned and articulated positions; anda specimen retrieval bag 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. 2. The surgical retrieval apparatus according to claim 1, wherein articulation of the end effector assembly is inhibited when the shaft is disposed in the first position. 3. The specimen retrieval apparatus according to claim 1, wherein the specimen retrieval bag includes a cinch cord disposed about an open end thereof, the cinch cord removably coupled to the plunger at an end thereof, the cinch cord configured, upon release from the plunger, for selective proximal translation to cinch closed the specimen retrieval bag. 4. The surgical retrieval apparatus according to claim 3, further comprising a pull-member releasably coupled to the plunger, the pull-member configured to engage an end of the cinch cord thereon such that, upon release from the plunger, the pull-member is proximally translatable to cinch closed the specimen retrieval bag. 5. The surgical retrieval apparatus according to claim 4, wherein the plunger includes at least one resilient lock tab configured to releasably engage the pull-member thereon. 6. The specimen retrieval apparatus according to claim 1, wherein the articulation mechanism includes an articulation bar coupled to the end effector assembly at a distal end thereof and has the articulation post disposed at a proximal end thereof, the articulation bar disposed within the shaft and translatable relative to the shaft to upon rotation of the handle relative to the shaft to articulate the end effector assembly relative to the shaft. 7. The surgical retrieval apparatus according to claim 1, further comprising a safety tab configured to engage both the handle and the shaft when the shaft is disposed in the first position to inhibit relative movement between the handle and the shaft. 8. The surgical retrieval apparatus according to claim 1, wherein the handle includes at least one finger hole defined therethrough to facilitate manipulation of the handle. 9. The surgical retrieval apparatus according to claim 1, wherein the plunger includes at least one flange extending outwardly therefrom that is configured to facilitate translation of the shaft between the first and second positions. 10. The surgical retrieval apparatus according to claim 1, wherein translation of the shaft from the second position back to the first position separates the specimen retrieval bag from the end effector assembly. 11. 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. 12. The surgical retrieval apparatus according to claim 1, wherein, in the first position of the shaft, the articulation post is spaced-apart from the articulation track and wherein, in the second position of the shaft, the articulation post is operably coupled with the articulation track.
