DEVICE AND METHOD FOR ASISSTING LAPAROSCOPIC SURGERY - RULE BASED APPROACH

摘要

A surgical controlling system comprising: a location estimating means to real-time locate the 3D spatial position of surgical tools, a movement detection means and movement database in communication with the location estimating means and with a control database and controller to control the position of surgical tools. The movement database stores 3D spatial positions of the surgical tools at the present time and at at least one previous time; movement has occurred if a present position is different from a previous position. In the control database are rules identifying tool movement as allowed or restricted, selected from: most used tool rule, right or left tool rule, field of view rule, no fly zone rule, route rule, environmental rule, operator input rule, proximity rule, collision prevention rule, history-based rule, tool-dependent allowed and restricted movement rule, preferred volume zone, preferred tool, movement detection rule, tagged tool rule, and change of speed rule.

1. A surgical controlling system, comprising:
a. at least one surgical tool adapted to be inserted into a surgical environment of a human body for assisting a surgical procedure; b. at least one location estimating means adapted to real-time locate the 3D spatial position of said at least one surgical tool at any given time t; c. at least one movement detection means communicable with a movement's database and with said location estimating means; said movement's database is adapted to store said 3D spatial position of said at least one surgical tool at time tf and at time t0, where tf>t0; said movement detection means is adapted to detect movement of said at least one surgical tool if the 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; and, d. a controller having a processing means communicable with a controller's database, said controller adapted to control the spatial position of said at least one surgical tool; said controller's database is in communication with said movement detection means; wherein said controller's database is adapted to store a predetermined set of rules according to which ALLOWED and RESTRICTED movements of said at least one surgical tool are determined, 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; wherein said predetermined set of rules comprises at least one rule selected from a group consisting of: most used tool rule, right tool rule, left tool rule, field of view rule, no fly zone rule, a route rule, environmental rule, operator input rule, proximity rule; collision prevention rule, history-based rule, tool-dependent allowed and RESTRICTED movements rule, preferred volume zone rule, preferred tool rule, movement detection 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 adapted 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 said location of said at least one surgical tool is substantially different from said n 3D spatial positions of said predefined route.
