Surgical system providing a reversible connection between two implants or between an implant and a tool of the surgical system

A surgical system, comprising first and second elements which are either two surgical implants or a surgical implant and a surgical instrument,

• wherein the first element includes:
• a first bearing face, and
• a first helical surface which extends from the first bearing face,
• and wherein the second element includes:
• a second bearing face, which matches the first bearing face,
• a second helical surface, which extends from the second bearing face and which is congruent with the first helical surface so that the first and second helical surfaces form a first helical connection between the first and second elements, centered on an axis, and
• a mechanism for controlling reversible connection between the first and second elements, the mechanism being suitable for being actuated successively:
• along a first movement, which includes a translation along the axis without involving rotation about the axis and by which the mechanism causes the first and second helical surfaces to mesh with each other until the first and second bearing faces are axially juxtaposed against each other, and
• along a second movement, which includes a rotation about the axis and by which the mechanism locks the first helical connection while the first and second bearing faces are pressed axially against each other.
