Abstract
A suction puncture device includes a puncture needle having an outer tube that has an opening edge of a first front end formed in the shape of a blade, and a stopper member that has a second front end disposed within the outer tube at a position separated from the first front end of the outer tube by a predetermined distance. A sample containing portion is formed between the second front end of the stopper member and the first front end of the outer tube. A ventilation passage is formed around the stopper member within the outer tube, a suction unit is connected to a first base end side of the outer tube, and the suction unit is communicated with and connected to the sample containing portion via the ventilation passage.
