腹腔鏡手術手技評価のための縫合結紮トレーニングパッドの三軸力覚センサ化

抄録

The purpose of this study is to develop a tactile-sensorized elastomer suture pad for laparoscopic surgery training. Although our previously-developed soft tactile sensor measuring iron particle core displacement with inductors is suitable for this aim, its structure should be improved so that the influence of the metallic surgery instruments such as suture needles and forcepses can be reduced. We proposed an improved structure and compared the sensor response ratio for suture needle approaching against force application of 1 N among several structure parameter conditions. As a result, we found that the sensor response ratio decreased to 10 ％ from 176 ％ by tuning the position and amount of the particle core, and the sensor thickness.
