This invention relates to a method for generating a virtual anatomic environment for use in minimally invasive surgery simulation, comprising the steps of: incorporating a main virtual anatomic environment (); selecting a local anatomic environment () from a predefined library () comprising a set of two or more simulated local anatomic environments (); including the selected local anatomic environment () in said main anatomic environment () to form a total virtual anatomic environment (). The invention also relates to a device for generating a virtual anatomic environment for use in minimally invasive surgery simulation, as well as a computer-based minimal-invasive surgery simulation system comprising such a device.

Device and method for generating a virtual anatomic environment

A method and a system are for simulating a surgical procedure on a bodily object, such as an organ, in a virtual environment. The virtual environment includes a three-dimensional mathematically described model of the bodily object which reflects geometrical and mechanical properties, and a virtual instrument that is controlled by a physical feeding device, which makes it possible to affect the model. The method includes the steps of representing a two-dimensional projection of the model by way of a video sequence containing a recorded view of a real bodily object, wherein engagement with the virtual instrument only involves interacting with the model. In addition, a method is for simulating an operation containing several surgical procedures.
