Abstract
A system and method for removing a tissue specimen or organ from the body of patient is disclosed. The system includes a bag and an excising instrument. The tissue specimen or organ is located in the bag, which is located in the patient's body. The instrument comprises a guide and a cutter. The guide is configured for introduction into the bag. The cutter is rotatable within the guide and includes a central passageway and an annular cutting blade. The cutting blade is brought into engagement with a peripherally located portion of the tissue specimen and rotated to produce a tangentially cut peripheral portion while a pulling force is applied to the tissue specimen through the central passageway. The pulling force rotates the tissue specimen within the bag to effect the production of the tangentially cut peripheral portion and to move the tangentially cut peripheral portion out of the patient's body. Gas pressure may be applied to inflate the bag to facilitate placement of the excising instrument.
