Claim:
1. A laparoscopic surgical device, the device comprising: a first member having a first gear at a first side of the first member; a second member having a second gear at a first side of the second member, the second gear corresponding to the first gear, and the second member being connected to the first member to enable tilting of the first member or the second member via movement of the first gear and the second gear engaged with each other; a connection member configured to connect the first member and the second member to each other; first wire mounting pieces respectively at the first member and the second member; second wire mounting pieces respectively at the first member and the second member; a first wire wound on the first wire mounting pieces so as to be pulled upon receiving a first amplified drive force from a drive unit; and a second wire wound on the second wire mounting pieces so as to be pulled upon receiving a second amplified drive force from the drive unit, the drive unit being configured to selectively transmit one of the first and second amplified driving forces to a respective one of the first member and the second member to cause tilting of the first member and the second member, wherein if the first wire is pulled by the drive unit, the first member and the second member are configured to tilt respectively based on the first and second amplified driving forces applied to the first member and the second member, and the first and second amplified driving forces correspond to N times a number of turns of the first wire and the second wire respectively wound on the first and second wire mounting pieces.
