1. A biological tissue sectioning device, comprising:
a laser emitter adapted for sectioning biological tissue in a region;
a controller, in communication with the laser emitter, adapted for activating and deactivating the laser emitter;
an optical module adapted for determining a surface of a tissue of the region in an operating mode; and
a central processing unit, in communication with the controller and with the optical module, adapted for:
defining at least one reference surface;
generating a numerical model of the region comprising, at least:
a shape of the surface of the tissue of the region,
a shape of the at least one reference surface, under which sectioning is prohibited,
a direction of a laser beam in which the laser emitter is oriented; and
activating the laser emitter if, in the numerical model, at least one position corresponding to at least one point of a straight line, representing the laser beam, and spaced from an intersection of the same straight line with the surface of the tissue by a distance equal to a sectioning depth, is located outside a prohibited region, said prohibited region being any of parts of the tissue of the region in which sectioning is prohibited.
