Preserving the brain function is essential while maximizing resection in brain tumor surgery. Image-guided surgery represents a substantial improvement in the completeness of brain tumor. In the brain tumor adjacent to the normal tissue, however, it is challenging to achieve the complete resection while preserving the normal function. The reason is that the current devices for tumor resection are difficult to remove the remnant tumor with minute volume control. For example, a suction tube is a main surgery device for the brain tumor. However, the precise volume control is difficult because the suction pressure is controlled by the operator's finger motion. In this paper, we propose a novel suction tube which has a cautery knife, sensors, magnetic valves, and a vacuum regulator. The tube can control removal volume and can stop the suction when the operator performed a danger operation.
