wherein the cutting of the physical tissue model with the laparoscopic surgical tools is augmented in real-time and displayed in the computing and display unit via overlaying digital textures on the physical tissue model and via acquiring, processing and displaying the video data and the signal data; and
wherein the open circuit of the internal wiring prompts the user to rectify the bleed by using the laparoscopic surgical tools to tie off the cut wiring, reestablishing an electrical connection with the electronic circuitry and thus turning off the bleeding trigger.
2. The apparatus of claim 1 , wherein the angle on the camera's principal axis is arranged to be perpendicular to the plane of the internal base plate.
3. The apparatus of claim 2 , wherein the angle on the camera's principal axis is substantially at 30 degrees to the plane of the side wall.
4. The apparatus of claim 1 , wherein the internal base plate is at an incline, which imaginary continuation plane is substantially at 30 degrees to the plane of the side wall.
5. The apparatus of claim 1 , wherein the internal base plate comprises a pigmented silicone background, which background is then used in the augmented video to project multiple backgrounds onto the surface during different procedures that occur in several regions of the body.
6. The apparatus of claim 1 , wherein the physical tissue model is replaceable and reconnectable to the circuitry, and wherein the physical tissue model is arranged to represent various human or animal tissue shapes, sizes and consistency, and the computing and display unit is programmable to represent an augmented video compatible with said tissue.
7. The apparatus of claim 1 , wherein the camera is arranged to track and extract data of the displacement of the physical tissue model, which data is then used to generate visual representations of said tissue in the augmented video.
8. The apparatus of claim 1 , wherein the camera is arranged to track and extract data of three dimensional movements of the laparoscopic surgical tools inserted in the surgical tools entry openings, which data is then used to generate visual representations of the laparoscopic surgical tools in the augmented video.
9. The apparatus of claim 1 , wherein two or more cameras are arranged to acquire stereoscopic depth related information from their field of view.
10. The apparatus of claim 1 , wherein the camera is in a camera housing, which housing further comprises lighting arranged to illuminate the inside of the physical simulator unit, wherein the lighting is arranged to enhance or discard for the camera elements of the physical tissue model, the background or of the laparoscopic tools.
11. The apparatus of claim 1 , wherein the physical simulator unit is in the shape of a box and comprises a top panel, a bottom panel, two parallel fixed side panels, two further side panels which are removable and parallel to each other; and wherein the side wall is the top panel.
12. A method for laparoscopic surgical training,
comprising the steps of:
holding a physical tissue model in a camera's field of view and in a position accessible to laparoscopic surgical tools;
