Feasibility of a Minimally Invasive Image-Guided Surgery System for Hepatic Procedures
This study was designed in two phases: Phase I is designed to confirm that the surgeon is able to perform accurate liver surface registration including standard liver features used as landmarks during a scheduled laparoscopic liver ablation procedure and acquires a level of comfort with the procedure.
The surface of the liver will be manually swabbed with the study tracked laparoscopic probe with landmarks noted during data collection. After registration of the liver is obtained, the registration points obtained during this procedure will be evaluated by the surgeon by moving the tracked laparoscopic probe over the liver surface and evaluating the location of the tracked laparoscopic probe displayed on the guidance system three dimensional (3D) image. The surgeon will accept or reject the registration accuracy.
The hypothesis is that the surgeon will be able to successfully acquire liver surface registrations with a small learning curve for technique and will be able to proceed to Phase II of the study.
Phase II contains the registration process included above but adds the additional process of tracking the ablation probe used to perform tumor ablation by attaching the Pathfinder Multi-Tool adaptor and collecting data showing the location of the ablation probe as tracked and displayed on the Pathfinder three dimensional (3D) image.
The surgeon will use ultrasound (US) guidance to locate tumor location during the laparoscopic procedure. The images collected during this process will be recorded by Pathfinder.

Descripción detallada
The Pathfinder System used during this study is used for data collection purposes only and is not used during the surgical procedure as an image guided system.
Preoperative computed tomography (CT) scans, obtained as standard of care, will be used to generate the image guided liver system 3D liver surface images used during the study.
During the laparoscopic procedure, the Pathfinder device will be inserted through the standard laparoscopic ports (5mm or 10mm) being used for the staging procedure.
A total study population will include 30 subjects: 10 in Phase I and 20 in Phase II that complete the laparoscopic procedure scheduled.

Medida de resultado |
Medida Descripción |
Periodo de tiempo |
---|---|---|
Phase I: The number of accurate liver surface registrations obtained in the laparoscopic environment providing the surgeon with a comfort level of adding the registration procedure to the scheduled laparoscopic surgical ablation procedure.
Periodo de tiempo: 30 Days
|
Subjects are followed for the study 30days (+/- 14 days) and are considered to have completed the study following this 30 day follow-up visit. The performance of accurate physical-to-image registrations obtained during laparoscopic procedures will be evaluated and accepted by the surgeon during the procedure. |
30 Days
|
Phase II: The number of surgical oblation procedures that present data showing equivalent location of the ablation probe when compared to the US and Pathfinder Guidance System 3D image data.
Periodo de tiempo: 30 Days
|
The correlation of location of the ablation probe will be evaluated comparing data obtained from the interoperative US images and the data collected with the Pathfinder image guided system.
