A surgical device includes one or more cameras integrated therein. The view of each of the one or more cameras can be integrated together and provided to a surgeon display and/or an assistant display. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the images generated by the one or more cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as at least partially transparent. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.
