A removable adapter (13) and tissue mount (14) is attached to the end of said piston rod (12). The handgrip (10) is further fashioned with a slot or cutout (16) into which is slidably disposed an L-shape metal rod (15), the upturned leg (17) of which supports a mirror finish metal block (18). Upon activation of the pneumatic cylinder (11) the tissue mount (14) is slammed against the mirror finish metal block (18) which has been precooled by immersion into a cryogen such as liquid nitrogen or helium.</p> |
