Hard tissue flattening device and hard tissue slice manufacturing method

The invention relates to a hard tissue flattening device and a hard tissue slice manufacturing method, and the hard tissue flattening device comprises a seat body assembly which comprises a bottom plate, and the bottom plate is provided with an accommodating area for accommodating a sample; the flattening assembly is connected with the base body assembly and comprises a pressing plate which is located above the bottom plate and can move up and down relative to the bottom plate and a first driving part used for driving the pressing plate to move up and down, and at least the surface, opposite to the containing area of the bottom plate, of the pressing plate is provided with a deformable elastic buffering layer. According to the hard tissue flattening device provided by the invention, the pressing plate provided with the elastic buffer layer ensures enough supporting force and provides enough buffer at the same time, so that the probability of fragmentation of a glass slide for bearing a sample is reduced; and
