Abstract
Laparoscopic surgery is a difficult procedure compared with open abdominal surgery. Therefore, training is necessary for surgeon to enhance the surgical skill for laparoscopic surgery. In this paper, we propose a novel training system to train an operation of ligation in laparoscopic surgery. The developed training system presents operator's operating force of the forceps, sudden operation of the forceps and straining of the shoulder to the operator. The operator's operating force of the forceps is measured by strain gauges and is displayed to the monitor together with the target force which was pre-measured from skilled-surgeon, so that the operator can learn appropriate operating force of the forceps. In addition, operator's forceps operation and surface electromyogram of the back muscle are measred, and when the operator's sudden operation of the forceps and straining of the shoulder are detected, the operator is warned acoustically. Fundamental tests were carried out to verify working state of the developed training system.
