Surgical tool for positioning a surgical device, surgical device and kit

A kit for positioning a surgical device, the kit comprising:

• a surgical tool and at least one surgical device, the surgical tool comprising:
• a gripping portion;
• a rod protruding from said gripping portion along a main development direction of the surgical tool up to a free end of the rod;
• a coupling system adapted to be coupled to at least one surgical device which can be engaged with a patient and the coupling system being operatively active at said free end;
• and
• said coupling system comprising an axial retention assembly comprising, at said free end of said rod, two opposite semispherical portions, wherein respective flat surfaces of the semispherical portions face each other and are separated from each other by an axial notch made partially along said rod, and said coupling system comprising a central clutch which is selectively movable between a locking position, in which the central clutch approaches the free end of said rod and is interposed between the two semispherical portions, preventing reciprocal approach thereof so as to block said two semispherical portions within a seat of said at least one surgical device, and a disengagement position, in which the central clutch moves away from the free end of said rod and at which the two semispherical portions can approach to allow said tool to come out of the at least one surgical device;
• wherein said coupling system comprises a rotational engaging assembly comprising a sleeve containing said rod inside, said rotational engaging assembly protruding from said gripping portion along said main development direction of the surgical tool up to a free end thereof which has a polygonal internal profile which can be engaged with said at least one surgical device;
• and
• the at least one surgical device comprising a gripping head configured to be coupled to the coupling system of said surgical tool, wherein the gripping head has a semispherical cavity adapted to be engaged with the coupling system of the surgical tool.
