Claims5
A surgical tool comprising:
- a main unit including a case and a hollow shaft provided on the case,
- a holder assembly for holding a living tissue within a body cavity, the holder assembly including a gripper,
- a tubular shaft that is inserted through the shaft so that when the holder assembly comes in contact with the shaft, the gripper being opened and closed depending on forward and backward movement of the tubular shaft,
- a wire configured to, separately from the tubular shaft, be inserted through the shaft to connect the main unit to the holder assembly,
- a driver that is provided on the case to cause forward and backward movement of the wire thereby varying a position of the holder assembly relative to a distal end of the shaft,
- a tension detector that detects a tension of the wire, and
- a controller configured to, when the holder assembly is separated from the distal end of the shaft, control the driver based on the tension detected by the tension detector.
