ABSTRACT:
A vacuum suction forceps includes a plurality of vacuum sucking portions, a plurality of arms, an arm opening/closing mechanism, and a main body. The sucking portions draw a suction target by vacuum suction. The arms support the vacuum sucking portions at distal ends thereof and have evacuating hollow portions. The arm opening/closing mechanism openably supports the arms to cause the vacuum sucking portions to be close to and separate from each other on the same plane. The main body is connected to the arm opening/closing mechanism and an evacuation tube. The main body turns on/off an evacuating operation of the vacuum sucking portions.
