The present invention relates to an easy-to-control tool for minimally
invasive surgery and a method for using the same. In accordance with an aspect of the present invention, there is provided a tool for minimally
invasive surgery and a method for using the same comprising, a main shaft, a first control shaft and a second control shaft positioned in sequence from one end of the main shaft, a first actuating shaft and a second actuating shaft positioned in sequence from the other end of the main shaft, an adjustment
handle positioned around one end of the second control shaft, an end
effector positioned around one end of the second actuating shaft, a
pitch control part positioned around one position of the positions between the main shaft and the first control shaft, between the first control shaft and the second control shaft, and between the second control shaft and the adjustment
handle, for transferring a motion of the adjustment
handle in a
pitch direction to the end
effector, a first
yaw control part and a second
yaw control part positioned around the other positions of the positions between the main shaft and the first control shaft, between the first control shaft and the second control shaft, and between the second control shaft and the adjustment handle, respectively, for transferring a motion of the adjustment handle in a
yaw direction to the end
effector, a
pitch actuating part positioned around one position of the positions between the main shaft and the first actuating shaft, between the first actuating shaft and the second actuating shaft, and between the second actuating shaft and the end effector, a first yaw actuating part and a second yaw actuating part positioned around the other positions of the positions between the main shaft and the first actuating shaft, between the first actuating shaft and the second actuating shaft, and between the second actuating shaft and the end effector, respectively, and a pitch cable, a first yaw cable, and a second yaw cable for transferring motions from the
pitch control part, the first
yaw control part, and the second
yaw control part to the pitch actuating part, the first yaw actuating part, and the second yaw actuating part.
