Since malignant brain tumor infiltrate the tissue and the boundary between normal and tumor tissue is unclear, it is difficult to remove completely by surgical operation. On the other hand, as there is a possibility of recurrence or malignancy, the improvement of tumor resection rate is strongly required. The purpose of the study is to construct a system that can gather many pathological specimens by resecting tumor continuously and decide extraction range in real time based on the biopsy results.Porcine brain used as an alternative of tumor was resected and collected using the continuous resection forceps developed in the study. Since the specimens was swept away in the column with a large amount of cleaning water, dehydration mechanism is necessary for diagnosis. Using the developed dehydration mechanism, most specimens can be collected with 70.24% dehydration rate, but some remained in the mechanism 4 times out of 10 trials.
