Abstract
A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. 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 composite image generated by the plurality of 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 transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.
Claims7
A medical apparatus comprising:
- a surgical retractor configured to hold open an incision and thereby provide a pathway for access of surgical tools to a surgical site;
- at least one video camera comprising imaging optics and an optical sensor, said at least one video camera disposed on said surgical retractor and configured to slide up and down said surgical retractor such that said at least one video camera can be positioned prior to insertion of a surgical tool in said pathway, said imaging optics comprising at least a positive lens and a negative lens, said positive lens in an optical path between said negative lens and said optical sensor, said negative lens more distal than said positive lens,
- wherein said imaging optics comprises wafer-scale optics.
