Safe and minially invasive palpaiton device for detection of lung tumor during thoracoscopic Surgery

摘要：

　　Though palpation is useful method to detect pulmonary nodules with open thoracotomy,it is very difficult in case of thoracoscopic surgery.We have developed a palpation device to this end.A pressure sensitive conductive rubber is used to measure hardness of tissue.The diameter of sensor units is small enough to pass thorough a trocar.The pressure-output property of the sensor unit was evaluated at laboratory.We could detect the tumor model in lung from in vivo experiments.Safety mechanism that limits the pressure applied by the palpation device was proposed.We are plan to apply the palpation device to endoscopic based navigation system.
