US 7776274 B2Abstract
Detents 144 are also formed on side walls 124 a-d for retaining a lid 150 in place. Lid 150 is coupled to cassette body 122 by a hinge 152. Lid 150 is formed to be stiffer than bottom wall 126 of cassette body 122 so that lid 150 may be used to press the tissue sample against the bottom wall 126 and to press the bottom wall 126 against the rigid bottom 74 of base mold 14 (FIG. 5). Lid 150 is formed by a plurality of ribs 154 generally separated by perforations 156 and each extending in a lengthwise elongated fashion toward a central area 150 a of lid 150. Lid 150 further includes side edges 158 a, 158 b extending lengthwise thereon and having a shallow “V” shape with a central apex 160 a, 160 b. Angle α (FIG. 10) is preferably about 4�. As with the first embodiment, the shape of side edges 158 a, 158 b complements similar shape of side walls 124 a, 124 b of cassette body 122. In this regard, these side walls 124 a, 124 b, either one of which may be the initial wall cut in the microtome, include respective apecies 162 a, 162 b. Respective ends 164 a, 164 b of lid 150 also complement the similar shape of cassette body side walls 124 c, 124 d to achieve a close fit of lid 150 within cassette body 122. The use of cassette 120 in the process of embedding one or more tissue samples, including the staging process within frame 12 and the embedding or molding process within base mold 14 is the same as described above with regard to FIGS. 1-8.
