Abstract
A surgical controlling system comprising: at least one location estimating means to real-time locate the 3D spatial position of at least one surgical tool; at least one movement detection means in communication with a movement database and with the location estimating means; and a controller, which controls the position of at least one surgical tool, in communication with a movement database, a control database and the movement detection means. The movement database stores the 3D spatial position of each surgical tool at the present time and at at least one previous time; a tool has moved if its present position is different from its previous position. The control database stores rules to identify a movement of a tool as either an ALLOWED movement or a RESTRICTED movement.
