Outline of Final Research Achievements

We developed a navigation technique with high temporal and spatial resolution using endoscopic image processing as intraoperative micro navigation technology for establishing intraoperative dynamics navigation device.
We developed basic motion-compensated suturing robot system that accurately moves the needle for surgical suture while compensating for the movement of the beating and swinging organs as an implementation and evaluation of navigation technology, and achieved an automatic detection of suture needle position with high precision, 2mm or less positioning error of needle insertion, and 60% reduction of force load during suturing.
