Abstract: An imaging system is provided for use with minimally invasive surgery. The imaging system comprises a platform which is anchored to a wall of a patient cavity. The platform comprises a plurality of transceivers which transmit energy toward the surgical site and receive reflected energy. The transceivers transmit rasterized image information to a computer which then displays the image information in real time, enabling a surgeon to view the surgical site on a display device. The transceivers can transmit and receive different types of energy, and the computer can then combine image information from the various different energy types to provide overlaid images of the surgical site. In addition, the computer controls the relative positions of the transceivers so that the images provided to the surgeon will not be affected by movement of the platform or by movement of structures (i.e., organs) at the surgical site.

Abstract: An insertion tool is provided for use in minimally invasive procedures for inserting surgical instruments, and in particular, camera assemblies, into patient cavities. Also provided is an anchor to position a camera in place in the cavity against an inner surface of the patient tissue.
