Surgical retractor with video cameras

摘要

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.

主权项

1. 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, the surgical retractor having a first end, a second end, a retractor frame configured to support surfaces that hold open the incision from of sides of the incision, and a longitudinal axis extending between the first and second ends, wherein the pathway extends along the longitudinal axis into the surgical site and the first end is more proximal than the second end; a proximal support frame comprising a camera platform and a curved support, the camera platform configured to move along the curved support the proximal support frame disposed above said retractor frame closer to said first end of said retractor than said second end of said retractor; and a plurality of video cameras inwardly facing toward the pathway, the video cameras comprising a distal video camera at a distal location with respect to said first end of said surgical retractor within said pathway provided by said surgical retractor, and a proximal video camera attached to the camera platform of said proximal support frame, wherein said proximal video camera is configured to be moved from one location on said proximal support frame to another location on said proximal support frame while still coupled to the proximal support frame.
