Abstract:
1. An interventional procedure simulation system, having a control unit and an interface unit, said control unit being a conventional computer communicating with said interface unit to simulate handling of a number of real nested instruments simultaneously interfaced by said interface unit and, said instruments being arranged to move and rotate independently of each other and said movements and rotations being propagated to the other instruments, said control unit including an instruction set comprising: a first instruction set for handling and processing an input from a user, based on said input, generating a second instruction set for controlling said interface, a first data set comprising characteristics for said instruments, a second data set comprising data on a body part to be simulated, a third instruction set for generating control signals relating to an interaction between said simulated instruments as well as between said simulated instruments and a surrounding geometry relating to a part of said simulated body part, said third instruction set being adapted to calculate an effect of said interaction on a shape of one or more of said simulated instruments, a fourth instruction set for controlling movements of a number of serially arranged and interconnected carriages corresponding to movements of said instruments in said interface unit, each carriage comprising: a fifth instruction set for calculating an effect of a first instrument inserted into a second instrument in a nested manner, each instrument having properties of at least one of a natural shape, stiffness, length, diameter and radioopacity, said instruction set being configured to calculate movements of said first instrument propagated to the second instrument and a sixth instruction set for modeling testing previously unknown tools by prototyping new tool features and simulating desired tool properties, wherein physical properties of the previously unknown tools are adapted to be changed in real-time.
