ABSTRACT:
The present invention provides an apparatus for retrieval, dissection and removal of small organs and tissue from a patient's body. The instrument includes a collapsible basket defining a basket cavity. An anvil is attached to the distal end of the basket to form an impacting surface. A cutting cannula defining a cutting cavity is positioned to be reciprocatingly movable to pass through the basket cavity and impact the anvil. The cutting cannula is manually and reciprocatingly driven to pass into and through the basket cavity, cutting any tissue contained in the basket cavity. The cut tissue is then suctioned from the body for analysis.
