Laparoscopic surgical simulator and port placement study.

We have developed a virtual laparoscopic surgical simulator and gathered data during student trial runs. The students performed simulated surgical dissections from 3 pairs of port positions with angles between the cutting and grasping instruments set to 60, 90, and 120 degrees. Preliminary data indicates improved performance at the 90 degree angle. Study updates can be found at http:¿www.hitl.washington.edu/research/lss
