Abstract
A grasper device for mini-invasive surgery procedures is provided, having two jaws, each of which having two elastically-deformable elements fixed one another and developing according to a main longitudinal direction, in particular a front element which contacts the tissue to be grasped and a back support element receiving a grasping force from a proximal command and having a higher modulus of elasticity than the front element. During the application of a grasping force Fz, the two elements deform along a transverse direction that is orthogonal to the main longitudinal direction and to the grasping force Fz.
