Device and method for assisting laparoscopic surgery rule based approach

摘要

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.

1. A surgical controlling system, comprising:
a. at least one surgical tool configured to be insertable into a surgical environment of a human body for assisting a surgical procedure; b. at least one location estimating means configured 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 configured to store said 3D spatial position of said at least one surgical tool at time tf and at time to; where tf>to; said movement detection means is configured 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 configured 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 a predetermined set of rules is storable in said controller's database, according to which ALLOWED and RESTRICTED movements of said at least one surgical tool are determinable; for each detected movement by said movement detection means, determination of said at least one detected movement as either an ALLOWED movement or as a RESTRICTED movement being according to said predetermined set of rulesfurther wherein there is associated a weighting function with each rule in said predetermined set of rules, said determination of said movement as either an allowed movement or a restricted movement being according to at least one said rule, selection of said at least one rule being by means of said weighting function.
