A tissue retrieval arrangement for enclosably retrieving body tissue from a mammalian body cavity. The retrieval arrangement comprises an elongated thin walled sheath-like retrieval bag having a proximal end and a distal end. A plurality of receiving tips are arranged on the distal end of the sheath to permit receipt of a grasper jaw in each of the receiving tips and thus permit safe retrieval of a body tissue between the receiving tips when moved by the grasper jaws. The bag is everted over the severed tissue once the receiving tips have grasped the tissue, and the now enclosed tissue and bag may be safely removed from the patient.
Forceps having two-half shells are disclosed. Each half-shell includes a front rim and a base wall and is mounted on a support element in a manner such that the half-shells can adopt a first opened-out configuration and a second closed configuration. The forceps include at least one container element having a cavity for receiving a plurality of biopsy samples. The container element is preferably associated with one of the half-shells.
The invention includes a forceps and collection assembly for acquiring and storing a plurality of tissue samples in a single pass, and accompanying mechanisms for use with the forceps and collection assembly. The accompanying mechanisms include an endoscope working channel cap assembly configured to minimize compression of a pouch of the forceps and collection assembly as it traverses a seal of the cap assembly, and a flush adapter configured to be coupled to the pouch so as to assist in removing tissue samples in the pouch by flowing fluid through the pouch.
