DEVICE FOR MECHANICALLY CHARACTERIZING AN ELEMENT OF INTEREST SUCH AS AN OOCYTE
First Claim
1. A device for mechanically characterizing an element of interest (E), advantageously a microscopic element of interest, possibly biological in nature, or even a cell,wherein the mechanical characterization device (1) comprises:
- support means (2), for receiving a container (C) suitable for containing a liquid medium,holding means (3), for holding said element of interest (E) in said liquid medium,an indenting member (4) having a longitudinal axis (4′
) and intended to remain in suspension in said liquid medium with said longitudinal axis (4′
) oriented horizontally, wherein said indenting member (4) includes at least one permanent magnet (45) and one proximal end (42) intended to indent said element of interest (E),magnetic means (5), for generating a magnetic field in which said indenting member (4) is intended to move and which participates in the suspension of said indenting member (4) with an unstable horizontal direction (x),control means (6), intended to pilot said magnetic means (5) so as to generate a variation of said magnetic field that is adapted to operate said indenting member (4) in translation along said unstable horizontal direction (x), andmeans (7) for determining the mechanical characteristics of said element of interest (E), taking into account the characteristics of said magnetic field and the value (D) of translational displacement of said indenting member (4) along said unstable horizontal direction (x) when said proximal end (42) of said indenting member (4) generates a compression force to said element of interest (E).

Abstract
Disclosed is a device for mechanically characterizing an element of interest, for example an oocyte. The mechanical characterization device includes: a support receiving a container suitable for containing a liquid medium; a holder for holding the element of interest; an indenting member; a magnet for generating a magnetic field in which the indenting member is intended to move and which participates in suspending the indenting member with an unstable horizontal direction oriented coaxially to the longitudinal axis; a controller to control the magnet to maneuver the indenting member in translation along the unstable horizontal direction; and a component for determining the mechanical characteristics of the element of interest.
