Abstract
A lifting device for laparoscopic procedures is provided with joints to enable an instrument carried by the device to be rotated to selectively adjust its pitch, roll and yaw. The adjustment provides a mechanism whereby the instrument may be connected to the arm in a variety of rotational orientations and accommodate different conditions to provide operating space within the body of a patient. Various mechanisms are provided to selectively lock the joints.
