1. A method for assisting an operator to perform a surgical procedure, comprising steps of:

  • a. providing a surgical controlling system, comprising;

    (i) at least one surgical tool;

    (ii) at least one location estimating means;

    (iii) at least one movement detection means; and

    , (iv) a controller having a processing means communicable with a controller'"'"'s database;

    b. inserting said at least one surgical tool into a surgical environment of a human body;

    c. real-time estimating the location of said at least one surgical tool within said surgical environment at any given time t; and

    ,d. detecting if there is movement of said at least one surgical tool if a 3D spatial position of said at least one surgical tool at time tf is different than said 3D spatial position of said at least one surgical tool at time to;

    e. controlling the spatial position of said at least one surgical tool within said surgical environment by means of said controller;

    wherein said step of controlling is performed by storing a predetermined set of rules in a controller'"'"'s database;

    said predetermined set of rules comprises ALLOWED and RESTRICTED movements of said at least one surgical tool, such that each detected movement by said movement detection means of said at least one surgical tool is determined as either an ALLOWED movement or as a RESTRICTED movement according to said predetermined set of rules;

    further comprising a step of selecting said predetermined set of rules from a group consisting of;

    most used tool, right tool rule, left tool rule, field of view rule, no fly zone rule, a route rule, an environmental rule, an operator input rule, a proximity rule;

    a collision prevention rule, preferred volume zone rule, preferred tool rule, movement detection rule, a history-based rule, a tool-dependent ALLOWED and RESTRICTED movements rule, tagged tool rule, change of speed rule and any combination thereof;

    wherein said route rule comprises a communicable database storing predefined route in which said at least one surgical tool is configured to move within said surgical environment;

    said predefined route comprises n 3D spatial positions of said at least one surgical tool;

    n is an integer greater than or equal to 2;

    said ALLOWED movements are movements in which said at least one surgical tool is located substantially in at least one of said n 3D spatial positions of said predefined route, and said RESTRICTED movements are movements in which the location of said at least one surgical tool is substantially different from said n 3D spatial positions of said predefined route.
