Abstract
Though medical technology has made a great progress recently, there are still many diseases difficult or impossible to cure. One of the problems is late detection of the diseases. We propose palpable endoscopes with the pressure sensor to develop the early-detection of diseases. Cancer tissue is known to be harder than normal tissue. In this study, In order to develop the palpation technology, we made a biological model of organs made of jelly. At first, we investigated whether jelly had young's modulus compatible with organs. The jelly with 15 % of concentration and 20 C of storage temperature was found to be appropriate. Next, we made the biological model of a cancer embedded in a normal tissue by using the jelly and then measured the young's modulus. We believe the proposed model is readily applicable to develop the next generation palpation technology.
