Biological material decomposition apparatus and corresponding manufacturing method, and cell suspension and tissue micrograft preparation method

摘要

The biological material decomposition apparatus (10) has a: a hollow outer body (11) that defines an inner chamber (12), and b: a plurality of micropores (13a) having sharp edges, An upper loading chamber (12a) which is accommodated in the inner chamber (12) in a transverse direction and is suitable for loading a biological material (MB) to be decomposed, and a biological material (MB ′) after being decomposed are collected. In cooperation with a fixed cracking grid (13) that defines a lower collection chamber (12b) suitable for carrying out and c: a fixed cracking grid (13) fixed in rotation, the upper loading chamber ( By supplying the biological material (MB) contained in 12a) and bringing it into contact with the micropores (13a) including the sharp edges of the decomposition lattice (13), the biological material (MB ′ Bladed rotor (rotating in the inner chamber (12), suitable for causing decomposition) Includes 4 and), the. The micropores (13a) of the resolving grid have a size or diameter of 70-80 μm. These micro-holes are die punches that use a conical or polygonal punch (P) to extract and tear a stainless steel metal sheet (N), for example with a jagged sharp edge containing six tips It can be obtained by a molding process of the type, or similarly using a laser light source within the scope of the molding process of the die punch type.
