Endoscopic instrument for ophthalmic surgery

Abstract

A surgical instrument comprises an elongate probe, in which the probe comprises an endoscope and a treatment channel. In some embodiments, the endoscope comprises a lens, in which the treatment channel extends through the distal end of the lens, which can facilitate alignment of the probe with a target tissue. In some embodiments, the treatment channel and the endoscope may comprise a co-axial configuration, which can decrease parallax when a user views the distal end of the working channel and target tissue beyond the distal end. Alternatively, the probe may comprise lenses arranged to provide stereoscopic vision of the end of the probe. The treatment channel may comprise an optical fiber to deliver light energy or a working channel. The treatment channel may comprise a housing such as a tube extending from the endoscope, in which the endoscope is configured to image the end of the treatment channel.
