3D-Vision-Laparoscopy

At our centre we have recently introduced this path breaking innovation that challenges the robotic surgery to date. We are the first urology team in India to perform lap surgeries using 3 D laparosocpy. 3 D laparoscopy is less costly compared to the robot as well as it gives the same results of a robotic surgery. Conventional two-dimensional laparoscopy has been limited by the lack of depth perception and spatial orientation. This disadvantage may affect surgical performance, operative time or morbidity. Depth perception, spatial resolution and accuracy may be improved by three-dimensional vision. Especially complex tasks like intracorporeal suturing and precise dissection, require a high degree of skill and depth perception. Two-dimensional imaging uses monocular references like motion parallax , relative position and size of anatomic structures, shading of light and dark, and tissue grading .Experience in laparoscopy though improves the processing of monocular cues. It can be assumed that these adaptions account for the increased mental fatigue and strain associated with two-dimensional imaging .Three-dimensional vision offers the advantage of improved depth perception and accuracy and separate input from 2 unique images allows for neural summation on a cortical level . The Einstein system, however, is a true three-dimensional imaging system with 2 separate optical channels and a light source. The 3D images present directly on the 32” full HD 3D LC Monitor. The image separation for each eye is provided by passive polarized glasses. The right and left eye receive unique images from the camera. Two imagers with true full HD resolution each are used. The 3-dimensional imaging system of the da Vinci robot, which is similar to the Einstein system, resulted in shorter performance times through increased peak velocity and acceleration and decreased rates of deceleration. Surgeons are able to perform more precise adjustments by using 3-dimensional vision when compared with 2-dimensional vision.3 D vision demonstrates a much better spacial resolution and depth perception. This benefit might well be noticed when complex and detailed skills such as intracorporeal suturing or difficult dissection are needed.
