Abstract
Abstract A reactor device for simultaneously retracting and viewing bodily tissues during a medical procedure. The retractor includes a blade member for retracting bodily tissues and an imaging device to form an image of the bodily tissues which are exposed by the operation of the blade member. The imaging device is coupled to a display device so that the image of the bodily tissues formed by the imaging device is displayed by the display device. Moreover, a method is provided for endoscopically performing a tissue retracting procedure using a retractor device. The method includes the steps of retracting bodily tissues using a retractor to form a cavity and imaging the cavity using an imaging device mounted on said retractor to form an image of the cavity and to provide the image of the cavity to a display device that is coupled to the imaging device.
