ABSTRACT:
A method and apparatus for preparing a tissue block for sectioning in a microtome includes positioning the tissue block on a platform. A vacuum-retracted membrane of plastic film material is used to draw an underside of the tissue block or specimen into planar contact with the platform. The user adjusts any peripheral edges of the tissue block that are not properly oriented so the underside is in a planar position. The tissue block is frozen on the platform once it is properly oriented. The membrane is subsequently peeled away from the platform and O.C.T. compound is applied to the tissue blocks. The O.C.T. compound after hardening and the tissue block are transferred to a second platform carried by a mounting device such that the tissue underside is exposed. The tissue specimen is ready for sectioning as part of the Mohs fresh tissue surgical technique.
