A surgical retrieval apparatus includes a tube assembly, a cartridge assembly, and a plunger assembly. The cartridge assembly is releasably engagable with the tube assembly and includes an end effector assembly disposed therein. The end effector assembly includes a specimen retrieval bag releasably coupled thereto at a distal end thereof and a first engagement member disposed at a proximal end thereof. The plunger assembly is configured for insertion through the tube assembly and into the cartridge assembly. The plunger assembly includes a second engagement member configured for releasably engaging the first engagement member. When the first and second engagement members are engaged with one another, the plunger assembly is movable between a more proximal position, wherein the end effector assembly and specimen retrieval bag are retracted within the cartridge assembly, and a more distal position, wherein the end effector assembly and specimen retrieval bag are deployed from the cartridge assembly.

1. A surgical apparatus, comprising: a tube having a first lumen extending longitudinally therethrough;a cartridge assembly including a housing defining a second lumen extending longitudinally therethrough and an end effector assembly operably disposed within the second lumen, the housing of the cartridge assembly configured to releasably engage the tube such that the first and second lumens communicate with one another;a plunger configured for insertion through the first and second lumens from a more proximal position, corresponding to a retracted position of the end effector assembly wherein the end effector assembly is retracted within the second lumen, to a more distal position, corresponding to a deployed position of the end effector assembly wherein the plunger urges the end effector assembly distally such that at least a portion of the end effector assembly is deployed distally from the second lumen; anda lock tab releasably engageable with the cartridge assembly distal to the end effector assembly, the lock tab including a finger configured to extend at least partially into the second lumen when the lock tab is engaged with the cartridge assembly such that the finger inhibits deployment of the end effector assembly. 2. The surgical apparatus according to claim 1, wherein the tube and the housing of the cartridge assembly are configured for releasable snap-fit engagement with one another. 3. The surgical apparatus according to claim 1, wherein the plunger is further movable through the first and second lumens to an eject position to disengage the tube and the housing of the cartridge assembly from one another. 4. The surgical apparatus according to claim 1, wherein the plunger is configured to releasably engage the end effector assembly such that movement of the plunger between the more proximal and more distal positions similarly moves the end effector assembly. 5. The surgical apparatus according to claim 4, wherein the plunger and the end effector assembly are configured for releasable snap-fit engagement with one another. 6. The surgical apparatus according to claim 1, wherein the end effector assembly includes a specimen retrieval bag configured to deploy distally from the second lumen upon movement of the end effector assembly to the deployed position. 7. The surgical apparatus according to claim 1, wherein the lock tab is configured for releasable engagement about at portion of an exterior surface of the housing of the cartridge assembly, and wherein the finger of the lock tab is configured to extend from the exterior surface of the housing through a slot defined within the housing into the second lumen. 8. A surgical apparatus, comprising: a tube;a cartridge assembly extending distally from the tube, the cartridge assembly including a housing, the housing and the tube cooperating to define a lumen extending longitudinally therethrough, the housing including an end effector assembly operably disposed therein;a plunger configured for insertion through the lumen from a more proximal position, corresponding to a retracted position of the end effector assembly wherein the end effector assembly is retracted within the lumen, to a more distal position, corresponding to a deployed position of the end effector assembly wherein at least a portion of the end effector assembly is deployed distally from the lumen; anda lock tab releasably engageable about a portion of the exterior of the housing of the cartridge assembly distal to the end effector assembly, the lock tab including a finger configured to extend through a slot defined within the housing at least partially into the lumen when the lock tab is engaged about the portion of the exterior of the housing such that the finger inhibits deployment of the end effector assembly. 9. The surgical apparatus according to claim 8, wherein the tube and the housing of the cartridge assembly are separate components configured for releasable engagement with one another. 10. The surgical apparatus according to claim 9, wherein the plunger is further movable through the lumen to an eject position to disengage the tube and the housing of the cartridge assembly from one another. 11. The surgical apparatus according to claim 8, wherein the plunger is configured to engage the end effector assembly such that movement of the plunger between the more proximal and more distal positions similarly moves the end effector assembly. 12. The surgical apparatus according to claim 8, wherein the end effector assembly includes a specimen retrieval bag configured to deploy distally from the lumen upon movement of the end effector assembly to the deployed position. 13. A surgical apparatus, comprising: a tube having a first lumen extending longitudinally therethrough;a cartridge assembly including a housing defining a second lumen extending longitudinally therethrough and an end effector assembly movably disposed within the second lumen, the housing of the cartridge assembly configured to releasably engage the tube such that the first and second lumens communicate with one another;a plunger configured for insertion through the first lumen and into the second lumen to engage the end effector assembly within the second lumen; anda lock tab releasably engaged with the cartridge assembly distal to the end effector assembly, the lock tab configured to inhibit distal movement of the end effector assembly relative to the housing when engaged with the cartridge assembly to facilitate engagement of the plunger with the end effector assembly upon insertion of the plunger through the first lumen and into the second lumen,wherein, with the plunger engaged with the end effector assembly and the lock tab removed, the plunger is movable through the first and second lumens between a more proximal position, corresponding to a retracted position of the end effector assembly wherein the end effector assembly is retracted within the second lumen, and a more distal position, corresponding to a deployed position of the end effector assembly wherein the at least a portion of the end effector assembly is deployed distally from the second lumen. 14. The surgical apparatus according to claim 13, wherein the tube and the housing of the cartridge assembly are configured for releasable snap-fit engagement with one another. 15. The surgical apparatus according to claim 13, wherein the plunger is further movable through the first and second lumens to an eject position to disengage the tube and the housing of the cartridge assembly from one another. 16. The surgical apparatus according to claim 13, wherein the plunger and the end effector assembly are configured for releasable snap-fit engagement with one another. 17. The surgical apparatus according to claim 13, wherein the end effector assembly includes a specimen retrieval bag configured to deploy distally from the second lumen upon movement of the end effector assembly to the deployed position. 18. The surgical apparatus according to claim 13, wherein the lock tab is configured for releasable engagement about at portion of an exterior surface of the housing of the cartridge assembly, and wherein the finger of the lock tab is configured to extend from the exterior surface of the housing through a slot defined within the housing and into the second lumen to engage the end effector assembly therein.
