ABSTRACT:
A tip cleaning accessory for enhancement in the utility of rigid endoscopic instruments is hereinafter disclosed. This accessory includes a complimentary tubular member adapted for use with a rigid endoscope. The endoscope contemplated for use with such an accessory includes a handset or handle, a rigid tubular shaft, having a plurality of functional channels adapted for acceptance of at least two fiber optic bundles, the first bundle for illuminating the operative field and a second bundle for visualization of the operative field, either directly through an eye piece (located within the instrument handset) or upon a video screen by coupling a video camera to the imaging bundle. The tip cleaning accessory of this invention comprises an adaptive and complimentary tubular member for use in conjunction with the endoscope to provide and direct a source of cleansing fluid to the tip of the endoscope so as to enable removal of debris from the optical windows associated with both the light and imaging bundles of the instrument. This accessory can be supplied along with new endoscopic instruments and is also compatible with endoscopic instruments of existing design.
