Abstract: The device (1) takes up the basic structure and operation of the McKibben type artificial muscles and similar, in which is provided a hollow cylindrical chamber (2), of resilient material, which is inflated in the active phase (K). The chamber (2) interacts with a braided sleeve (3), consisting of threads (31, 32), almost inextensible, arranged in crossed helical paths having a characteristic angle of inclination β with respect to the longitudinal axis (X) of the device (1). The sleeve (3) is connected at the ends with two rigid head members (4A, 4B) provided to be mechanically connected to external bodies. The invention provides adjusting means (5), associated to said rigid head members (4A, 4B) adapted to vary their distance (D) at rest, so as to require a proportional and consistent change in the angle of inclination β: if the latter is exactly 54.7°, the device (1), in the active phase (K) stiffens without dimensional changes, if the angle β is greater an axial extension is obtained, if the angle β is smaller an axial contraction is obtained.

Abstract: A mechanical end-effector for minimally invasive surgery (MIS) equipped with a mechanochromic indicator for providing the surgeon with visual indication of the force applied upon a tissue is disclosed. The indicator includes a polymeric matrix functionalized with mechanochromic molecules, wherein a prepolymer/curing agent weight ratio used for preparing the matrix is in the range 1:1-15:1 and the percentage by weight of the mechanochromic molecules in the matrix is in the range 0.1-5%.

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.

Abstract: Composite material comprising a matrix of elastic and electrically insulating material, and a filler of electrically conducting material embedded within the matrix. The filler forms a conductive path defining an active electrode adapted to be associated with a reference electrode for forming an electrical signal output. A deformable gap is formed between an outer surface of the conductive path and an inner surface of the matrix, in such a way that the application of a mechanical load to the composite material causes the surface of the conductive path and the surface of the matrix to be brought closer together, and the removal of the mechanical load causes the surface of the conductive path and the surface of the matrix to be moved away from one another as a result of the elastic force of the material of the matrix.

Abstract: A system includes an excavation assembly, which in turn includes a supporting body having a perimetric edge defining a closed path. A distribution apparatus protrudes transversally relative to the perimetric edge and is movable in a guided manner on the supporting body. The distribution apparatus transversally distributes a quantity of hardenable or solidifiable material towards the outside of the perimetric edge, so as to be able to lay a plurality of axially superimposed annular layers(s) of the hardenable or solidifiable material defining a tubular structure (T) around the excavation assembly. A motor device moves the distribution apparatus on the supporting body.
