SURGICAL DEVICE WITH INTEGRALLY MOUNTED IMAGE SENSOR

摘要

A surgical device for use with a video display and for retracting, viewing , and accessing tissue is described. The surgical device comprises an elongate d 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 a n instrument. The surgical device further comprises an image sensor attached t o 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 withi n 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.
