  • Patent number: 9579163
    Abstract: Robotic platform for mini-invasive surgery comprising robotic arms (4a, 4b) suitable to be placed in the body of a patient, introduced through a single access port, which are an extension of external robotic manipulators (19). The continuity between external (1) and internal (4a, 4b) robotic arms is guaranteed by means of a trans-abdominal magnetic connection (6) between the internal robotic arm integral with the external one. The trans-abdominal magnetic coupling not only guarantees a stable anchoring, but most of all it transfers degrees of freedom to the internal robotic arms, inducing the motion of internal magnets by means of the automatized motion of external magnets. It is also possible to reposition the internal robotic arms without requiring having to additionally perform incisions on the abdomen. Using the external robotic arms allows translating the internal ones on the entire abdomen thus providing a working space not bound to the point of insertion and theoretically unlimited.

Also provided is a pneumatic actuator of a mobile jaw of the anchors sliding axially on a multichannel support, wherein at least one suction hole is formed for generating a vacuum suitable for drawing surrounding tissue of the body cavity into the anchors. A relatively evenly perforated diaphragm is placed, coaxially with the support, at the suction hole and in a spaced relationship from the surface of the support, the width of the perforations being generally smaller than that of the suction hole.
