Title:
SYSTEM FOR MONITORING SURGICAL SITE AND METHOD FOR MONITORING SURGICAL SITE
Document Type and Number:
WIPO Patent Application WO/2018/061423
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable, even in an endoscopic operation, an operation upon a specific operation site while monitoring the overall surgical site, such as an organ. An artificial magnetic field is generated such that a surgical site of a patient is positioned within a generated three-dimensional artificial magnetic field space. A plurality of magnetic sensors are respectively mounted in a plurality of predetermined locations of the surgical site of the patient. Data of a 3-D image of the surgical site and position information of the mounting locations of the magnetic sensors with respect to the surgical site are stored in a storage unit as position information of the mounting locations with respect to the 3-D image of the surgical site. On the basis of the stored 3-D image data and the position information of the mounting locations of the magnetic sensors with respect to the 3-D image of the surgical site, and output information from the plurality of magnetic sensors, a control unit displays the 3-D image of the surgical site of the patient upon a display screen of a monitor unit so as to correspond to the state of the presence of the surgical site within the artificial magnetic field space.
