Abstract: A device for surgical interventions comprises (i) an inner end (1) guidable/steerable to an operation field, (ii) an outer end (3) operated by user and (iii) a middle part (2) which connects both ends (1, 3) together. Force transmission units extend between the outer end (3) and the inner end (1). The force transmission units, the outer and the inner ends and the middle part (2) transfer movements of the outer end (3) to the inner end (1) in an identical measure, as if the inner end (1) was a straight continuation of the outer end (3).

Abstract: A surgical stapling instrument (1) comprises a staple fastening assembly (4) in the distal region of said instrument, the staple fastening assembly (4) including a cartridge device (8) which comprises at least one closed row (17, 18) of staples and defines a wavy distal end surface (14), and an anvil (9) which defines a wavy proximal staple forming surface (20) substantially matching the distal end surface (14) and which is adapted to cooperate with the cartridge device (8) for forming the ends of the staples exiting from the cartridge device (8), wherein the distal end surface (14) and the staple forming surface (20) have a globally wavy shape including two opposite peaks (21) and two opposite valleys (22) angularly spaced at about 90° from the adjacent peaks (21) and in that said two-peaks-two-valleys wavy shape is formed by a stepped configuration of said surfaces (14, 20).

Abstract: A surgical stapler includes a head in which a plurality of staples are stored. The head includes a facing surface. The stapler also includes an anvil having an anvil surface shaped and dimensioned for forming the staples upon actuation of the surgical stapler, the anvil including a facing surface opposed to the facing surface of the head for mating engagement therewith. The facing surface of the head is obliquely oriented relative to a longitudinal axis of the head creating an elliptical staple line when the head is brought into contact with anvil during actuation of the surgical stapler.

Abstract: A surgical stapling instrument comprises a frame having a body portion and a handle. A staple fastening assembly is provided in the distal region of the instrument and includes a cartridge device, which comprises at least one closed row (10, 12) of staples, and an anvil. The anvil is movable relative to the cartridge device and is adapted to cooperate with the cartridge device for forming the ends of the staples exiting from the cartridge device. A knife, which has a closed cutting edge, is contained within the cartridge device and is positioned such that there is at least one closed row (10, 12) of staples on the outside of the cutting edge. It can be moved towards the anvil. The line along which the closed row (10, 12) of staples is arranged has a stepped shape, leaving a plane perpendicular to the longitudinal axis of the staple fastening assembly, such that this line has a larger total length than the projection of this line onto this plane.
