A surgical retrieval apparatus (10) includes a tube assembly (100), a cartridge assembly (300), and a plunger assembly (200). The cartridge assembly is releasably engagable with the tube assembly and includes an end effector assembly (320) disposed therein. The end effector assembly includes a specimen retrieval bag (330) 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. |
