Laparoscopic navigation pointer for three-dimensional image–guided surgery

Abstract

In the reported cases, the LNP was a useful tool for image guidance in laparoscopic surgery, both for planning the surgical approach in detail and for guidance. The authors believe that adominal 3D image guidance using an LNP has a large potential for improving laparoscopic surgery, especially when vessels and anatomic relations may be difficult to identify using only a laparoscope. Accordingly, they believe this new technology could increase safety and make it easier for the surgeon to perform successful laparoscopic surgery.

Navigated ultrasound in laparoscopic surgery

“…In laparoscopy, we have experienced that when the lesion is located in the retroperitoneum, only minor shifts in anatomy are detected (Mårvik et al, 2004), which may be compensated by using 3D ultrasound to acquire updated maps of the anatomy. Nevertheless, tissue motion and deformations during surgery require continuous correction and update of images for constant and reliable navigation accuracy.…”

“…Various display and visualizations methods of both instruments and the medical images can be used. Preoperative images are useful for planning as well as for guidance during the initial phase of the procedure as long as the target area is in the retroperitoneum (Mårvik et al, 2004). When preoperative images are registrated to the patient, the surgeon is able to use navigation to plan the surgical pathway from the tip of the instrument to the target site inside the patient.…”

Optical techniques for 3D surface reconstruction in computer-assisted laparoscopic surgery

“…(Marescaux et al, 2004;Mutter et al, 2010;Nozaki et al, 2012;Pratt et al, 2012)) proposed manual alignment of pre-operatively and intra-operatively acquired images. The majority of (semi-) automatic approaches for registering the endoscopic image data with 3D anatomical data acquired pre-or intra-operatively are either marker-based (Baumhauer et al, 2008;Falk et al, 2005;Ieiri et al, 2011;Marvik et al, 2004;Megali et al, 2008;Mourgues et al, 2003;Simpfendorfer et al, 2011;Suzuki et al, 2008) or use external tracking devices that are initially calibrated with respect to the imaging modality (Ukimura and Gill, 2008;Konishi et al, 2007;Shekhar et al, 2010;Feuerstein et al, 2008;Konishi et al, 2007;Feuerstein et al, 2007;Leven et al, 2005;Blackall et al, 2000)). In an alternative approach, reconstructed surface data may be used to perform the registration with pre-operative models (Audette et al, 2000).…”

An augmented reality system for liver thermal ablation: Design and evaluation on clinical cases

“…In the context of laparoscopy guidance, Marvik [37] proposed an interface that showed the tool position with respect to the 3D reconstructed model. In addition, they display the 3 CT-slices where the tip of the laparoscope lies.…”
