  • Surgical device with integrally mounted image sensor
    Patent number: 6139489
    Abstract: A surgical device for use with a video display and for retracting, viewing, and accessing tissue is described. The surgical device comprises an elongated platform and a concave head connected to a distal end of the platform. The concave head defines a cavity that provides a working space for an end-effector of an instrument. The surgical device further comprises an image sensor attached to the inside of the concave head so that tissue within the working space may be imaged by the image sensor to provide an electrical signal for a video display. The surgical device further comprises an illumination means for illuminating tissue within and adjacent to the cavity of the concave head. A power source is provided for powering the image sensor and the illumination means. A handle is attached to the proximal end of the platform.
