Navigation in Liver Surgery
Project Description
Laparoscopic surgery presents a minimally invasive alternative for liver surgery and has a number of clinical advantages. However, it is complicated by reduced depth perception and the loss of tactile feedback, which can be compensated with a navigation system.
In sub - project PNT–4 (Laparoscopy-Assistant), an assistance system for navigated laparoscopic liver surgery has been developed. By integrating ultrasound, laparoscopic images and instruments the system compensates for the loss of tactile feedback and reduced depth perception.
Moreover, it helps the surgeon to fuse the preoperative planning data with intra-operative ultrasound and video images and to navigate the surgical instruments and laparoscopic ultrasound probe using an electromagnetic tracking system. The system fulfills all requirements presented at the beginning or during the project and was validated with respect to quality and risk aspects. It was approved for a clinical investigation according to annex VIII of the Medical Devices Act.
