Detachable surgical tool configured as a finite state machine

A surgical tool, comprising:

• a first body, a second body, and a third body;
• a detachable structural interface establishable between said first body and said second body;
• a joint residing between said first body and said third body, said joint having at least two degrees of freedom;
• a first lock establishable between said first body and said second body, upon its establishment said first lock maintains establishment of said detachable structural interface;
• and
• a second lock establishable between said first body and said third body;
• wherein, in a first state of the surgical tool, said detachable structural interface lacks establishment, said first lock lacks establishment, and said second lock is established and said second lock disenables the at least two degrees of freedom of said joint;
• and
• wherein, in a second state of the surgical tool, said detachable structural interface is established, said first lock is established, the action of establishing said detachable structural interface prompts disestablish-ability of said second lock and said second lock, upon its disestablishment, enables the at least two degrees of freedom of said joint.

A surgical tool, comprising:

• a first body, a second body, a third body, and a fourth body;
• a first detachable structural interface establishable between said first body and said second body;
• a first assembly constituted by said first body and said second body upon establishment of said first detachable structural interface;
• a second detachable structural interface establishable between said third body and said fourth body;
• and
• a second assembly constituted by said third body and said fourth body upon establishment of said second detachable structural interface;
• wherein said first detachable structural interface and said second detachable structural interface provide independent mechanical energy transmission paths;
• and
• wherein said first body or said second body of said first assembly is directly coupled to said third body or said fourth body of said second assembly via a joint, said joint having at least one degree of freedom.
