摘要：
A flexible drill bit comprising:a proximal shaft portion for connecting to a source of turning；a distal cutting tip portion for boring into a material； andan intermediate shaft portion extending between the proximal shaft portion and the distal cutting tip portion, the intermediate shaft portion being characterized by (i) sufficient longitudinal flexibility so as to permit the flexible drill bit to be passed along a curve, and (ii) sufficient torsional strength to permit the flexible drill bit to bore into the material.
