and the protruberance 935 a ratchet mechanism not shown can be provided to prevent rotation of a tray opposite to a predetermined direction preferably a stop 936 is also provided on the tray 904 to prevent the tray from being rotated through more than one cycle without first retrieving the samples received in the cups i e to prevent contamination of an earlier retrieved sample by a later retrieved sample the tray is also preferably provided with indicia 938 to indicate to the practitioner which cup is currently positioned to receive a sample after an individual sample has been received into a first cup according to a similar method as described above with respect to the first embodiment the aspiration and irrigation are interrupted and the tray 904 is rotated such that the next cup is positioned between the first aspiration connector 918 and the proximal aspiration conduit 924 the process is repeated after each sample is received into a cup once the practitioner has obtained all of the desired samples or once each cup of the tray contains a sample the threaded connector 906 is uncoupled and the tray is removed and the samples may be removed from the cups of the tray index numbers adjacent the cups indicate the order in which the samples were retrieved turning to fig1 and 20 a third embodiment of a multiple sample biopsy forceps instrument 210 is shown the instrument includes a proximal actuation handle 212 a flexible multi lumen.
