Microtome sectional biopsy support to orient tissue samples

摘要

A histological device for supporting tissue samples, for orienting and retaining tissue samples during processing, imbibition and sectioning with a microtome, comprising a tissue case, including the tissue case a perforated bottom wall and at least one side wall perforated, to define a tissue sample reception space, the case being formed by a material that can be successfully sectioned with a microtome and that is resistant to degradation by solvents and chemicals that are used to fix, process and dye tissue , including the tissue case a first and second elongated channels (130a) to receive at least one sample (100) of tissue, the first and second channels (130a) being separated from each other by a separation structure, the structure of which is connected separation with the bottom wall and extending upwards from it, and including an anchoring element that incl a surface oriented towards the bottom wall is used to anchor the separation structure in an imbibition material, during a microtome sectioning process, and the tissue sample deflection structure is configured to extend into the first and second channels (103a ), to retain the tissue sample or samples against the lower wall during processing and imbibition, the tissue sample deflection structure being able to be further sectioned with the microtome, characterized in that the device additionally comprises nails (140, 142 ) on opposite sides of the first and second channels (130a), to hold the tissue sample or samples in a desired orientation.
