Viking Systems, Inc. Research Collaborators Demonstrate That 3-D Vision Significantly Improves Precision, Accuracy and Time in MIS Surgical Procedures

Poster Given At the AUA Annual Meeting 2007 in Anaheim, CA, Highlights the Advantages of the Viking 3Di Vision System in Laparoscopic Suturing

SAN DIEGO, May 22, 2007 (Healthcare Sales & Marketing Network) -- Viking Systems, Inc. (OTC BB:VKSY.OB ), a designer, manufacturer and marketer of high-performance laparoscopic vision systems for use in minimally invasive surgical (MIS) procedures, announces that a poster by Dr. Jihad H. Kaouk, M.D., et al. of Cleveland Clinic in Cleveland, Ohio, entitled ``Suturing Using Articulated Needle Drivers and 3-D Vision,'' has been presented at the Annual Urology Association (AUA) meeting in Anaheim, California. The poster demonstrates the advantages of using 3-D vision in laparoscopic suturing procedures in a pelvic trainer.

The researchers found that precision and accuracy were improved across all subject groups using novel articulated needle drivers (AND) and 3-D vision compared to straight conventional needle drivers (CND), which have a limited range of freedom. It was also demonstrated that 3-D vision especially reduced the time to accomplish the tasks in the intermediate group, and the combination of AND and 3-D vision showed benefits in both intermediate and novice groups.

``Intracorporeal laparoscopic free-hand suturing using straight conventional needle drivers (CND) and two-dimensional (2-D) vision, may be technically challenging,'' said Dr. Kaouk. ``Combination of articulated needle drivers (AND) and 3-D vision seems to enhance surgeons precision and accuracy.''

To complete the study, fifteen urologists were divided into 3 groups according to their laparoscopic experience, and were asked to perform two specific laparoscopic suturing tasks following 20 minutes of AND practice that measured performance with and without 3-D vision. Total time for each line of suturing, time for knot tying, time to accomplish urethro-vesical anastomosis, precision and accuracy were compared.
