A device for mechanical fragmentation of tissues facilitates preparation of the composition of isolated cells from a tissue sample, the preparation including mechanical fragmentation of the tissue, the device including a motorized support and a container, the motorized support including a motor having a rotor secured to a coupling member, the container internally including a rotary shaft with radial arms sweeping the inside of the container as the shaft rotates, the motorized support and the container including a complementary securing unit that allow the container to be immobilized on the motorized support, the coupling member and the rotary shaft being configured in such a way as to allow axial rotation of the rotary shaft when the rotor of the motor is turning. The radial arms are of two types: rigid vane-type arms, and flexible filamentary-type arms, notably made of nylon or of metal. A corresponding method is also disclosed.
A device for the mechanical fragmentation of tissues intended for the preparation of a composition of isolated cells, in particular adipocytes and/or cells contained in the adipose tissue, from a tissue sample, obtained in particular during a liposuction, said preparation including at least one step of mechanically fragmenting the tissues in the device, said device comprising a motorized support (3) and a container (1), the motorized support (3) comprising a motor having a rotor integral with a coupling member, the container (1) internally including an axially rotatable rotary shaft (9) and including radial arms (10, 12) capable of sweeping the inside of the container (1) as the rotary shaft (9) rotates, the motorized support (3) and the container (1) including complementary detachable fastening means (11) for immobilizing the container (1) on the motorized support (3), the coupling member and the rotary shaft (9) being configured in such a way as to allow axial rotation of the rotary shaft (9) as the motor rotor rotates,
