The present invention provides a system to evaluate of Tissue Manipulation Events (TMEs) performed on a subject, by a practitioner and providing a corresponding ranking-score thereof. The system includes a contour image capturing and recording devices adapted to capture and record, in real time, the contours of a surgical tool and a tissue and tissue manipulating events of a subject, which are connected to a data receiver for receiving the vector image data. At least a database including bench-mark surgical parameters, tissue and tool parameters are connected to the system. A processor coupled to the data receiver and the databases and configured to convert the vector image data (raw image) into pixelated frames, evaluate tissue manipulation events and generate a performance score for the task performed on the subject. The present invention also provides a method for evaluation of manual skills in tissue manipulating events performed.
