Abstract
The endoscope is widely used for various diagnoses and treatments in Minimally Invasive Surgery (MIS), such as hysteroscopy, laparoscopy and colonoscopy. However, the limited field of image of the endoscope is often the most problematic issue faced by surgeons and medical students, especially for those inexperienced physicians, which leads to difficulty during surgical operations. To reduce the difficulties of MIS with respect to endoscope function, the proposed technique provides the angle and distance from the surgical instrument to the lesion. The in-time guiding information provides global positioning information by tracking the lesion position during surgery. The whole system has been successfully validated in animal in vivo experiments. As the view of the scope is limited by the endoscope, and when the surgical instrument moves, the lesion and instrument relating location information is lost. As the global position information is lost, the surgical risk increases. Hence, the proposed technique of this current research provides the angle and distance from the surgical instrument to the lesion. This can help the doctor obtain the needed global positioning information. The risk situation occurs when the surgical three-dimensional positioning information is lost. Hence, the image guiding requirement is urgently needed for increased precision in surgical operations, such as in heart and brain surgeries. The proposed in-time image guiding technique applies to the HSV object-tracking method. This technique provides the distance and angle information in order to help doctors perform successful surgical operations. The guiding information prevents the surgical errors from occurring due to the limited image of field of the endoscope. The proposed technique can also be adopted to decrease the training cost of new doctors. During a survey of the previously published researches, to our knowledge, there are no similar works in image guiding for MIS.
