Robot, particularly for mini-invasive surgery through a single parietal incision or natural orifice
A robot configured for mini-invasive surgery through a single parietal incision and/or natural orifice includes at least one articulated support, a stiffening component, and at least one maneuvering element. The articulated support includes a plurality of rigid bodies that are mutually associated. The stiffening component is associated with the articulated support and adapted for the transition of the articulated support from an inactive configuration, in which the rigid bodies can move with respect to each other, to an active configuration, in which the rigid bodies are mutually aligned so as to form a guide, and vice versa. The least one maneuvering element can be associated slidingly with the guide of the articulated body in its active configuration and can engage selectively a plurality of operating instruments accommodated in at least one container body that can be associated with the articulated support in its active configuration.
1. A robot for mini-invasive surgery through a single parietal incision or natural orifice comprising:
at least one articulated support, which comprises a plurality of rigid bodies pivotally engaged to each other;
an imager integrated within said articulated support;
at least one tensioning element incorporated in said articulated support and configured to transition of said articulated support from an inactive configuration, in which said rigid bodies are movable relative each other, to an active configuration, in which said rigid bodies are fixed relative each other forming a guide, and vice versa;
at least one container body fixed to a distal end of said articulated support and configured to store a plurality of operating instruments simultaneously;
at least one robotic arm slidingly engaged with said guide of said articulated support in said active configuration and configured to selectively engage the plurality of operating instruments stored in said at least one container body when the articulated support is in the active configuration, while the robotic arm and the container body are disposed in a body cavity, wherein said rigid bodies have a hollow conical end and a convex conical end, wherein the hollow conical end and the convex conical end of adjacent rigid bodies are configured to engage each other by tensioning said at least one tensioning element to transition said articulated support into the active configuration;
wherein said articulated support comprises at least one guiding carriage having engagement mechanisms configured to engage with engagement mechanisms of the robotic arm enabling the robotic arm to translate and rotate with respect to said articulated support, and translation means configured to translate said at least one guiding carriage in said guide.
2. The robot according to claim 1 , comprising insertion means adapted to guide said articulated support in said inactive configuration and said at least one robotic arm within a surgical area through an access opening.
3. The robot according to claim 1 , wherein said container body is connected with at least one end of said articulated support.
4. The robot according to claim 1 , wherein said robotic arm includes 7 degrees of freedom.
5. The robot according to claim 1 , wherein said tensioning element comprises tensioning cables that pass through said articulated support and are actuated by a motor, said active configuration being obtained by shape mating of a female end with a male end of two consecutive rigid bodies.
6. The robot according to claim 1 , wherein said translation means comprise at least one translation cable that is connected at one end to said at least one guiding carriage and wound, at the opposite end, on a pulley keyed to a driving shaft of a motor.
7. The robot according to claim 1 , wherein said container body includes a plurality of safety devices adapted to ensure that said operating instruments are always associated alternatively with said container body or with said robotic arm.
