Abstract:
Laparoscopic technique is now widely used in gastrointestinal surgery, but the limitation of its “tubular vision” pose disadvantages. Benefits from the realization of dynamic navigation which can match the preoperative dimensional reconstruction model and the surgical scene in real time, the computer-aided surgery(CAS) can supplement the insufficiency of laparoscopic view. Focusing on pancreas, the key organ in the laparoscopic gastrectomy for cancer cancer,the initial experience of dynamic navigation in such surgery using a virtual surgical model is shared. The method is as follows: First, the virtual model of pancreas and peripheral blood vessels was reconstructed with the Mimics17.0 based on the abdominal computed tomography data of the patients with gastric cancer; and the location information of the virtual marker was captured with the tracking software. Second, the three dimensional (3D) construction image displayed in SLT file, was read in ZEditTM3.21 and was printed by Spectrum ZTM510 printer. Then, the 3D model was fixed in a laparoscopic simulation training device to achieve the simulation operation. The location information of the laparoscopic training device , lens and laparoscopic instrument was recorded with tracking software. Besides, the coordinate information of simulation operation was also achieved. Third, we conducted a match between the virtual and simulation operation. Our study show that scenes splitting is conducive to the tracking and matching of the surgical navigation in laparoscopic surgery for gastric cancer.
