Medical borescopes and related methods. In some embodiments, a medical borescope may comprise a handle and a tube extending from the handle. The tube may be partially, or wholly, defined by an at least substantially non-conductive material, such as a suitable plastic, ceramic, or other non-metallic material. The borescope may further comprise a tip assembly positioned at a distal end of the tube, which may comprise an image sensor configured to take images through the distal end of the tube.
