The invention relates to a technique of cultivating thin pieces of bio-tissue for a long period of time while maintaining the freshness thereof. There is provided a device for manufacturing thin slice pieces of bio-tissue, which includes a loading table, on which there is provided an upper lid that has slits formed therein for permitting the passage of blade members therethrough and there is also provided between the loading table and the upper lid a core having slits formed therein for permitting the passage of the blade members therethrough. The thin slice pieces of bio-tissue may be obtained by having a living-body specimen loaded on the loading table of a specimen transfer part and moving the living-body specimen toward the blade members and then cutting it off. Those thin slice pieces of bio-tissue may alternatively be obtained by having a living body specimen loaded on the loading table of a fixed specimen-retaining part and moving the blade members in an up-and-down direction. Furthermore, in order to take out the thin slice pieces of bio-tissue from the slicer, it is possible to use a film frame having pasted thereon a film that is to be inserted into the slits.
A device for manufacturing thin slice specimens of bio-tissue, comprising a plurality of blade members each of that is shaped like a circular disk and has a ceramic-made blade on its circumference that has the same diameter, a blade member-supporting shaft that retains the circular disk shaped blade members at prescribed intervals and in parallel with one another so that they are coaxially rotatable, a specimen transfer part that is retained so that the blade members can be inserted thereinto and is movable, and a box-shaped upper lid that is disposed on a loading table of the specimen transfer part, wherein the top plate, as well as the side plates in the movement direction, of the box-shaped upper lid has formed therein slits that permit the passage of the blade members.
