Abstract:
1. A drill attachment comprising: a drill member comprising: (a) a rotatable drive shaft for communication with a drive input, the rotatable drive shaft including a distal flexible portion; (b) a drill tip associated with the distal flexible portion of the rotatable drive shaft so as to rotate with the rotatable drive shaft; (c) a sheath for enveloping at least a portion of the distal flexible portion of the rotatable drive shaft, the sheath including a plurality of segments; and (d) an outer conduit through which the sheath extends and is movable therethrough, wherein at least part of said sheath is sized for insertion into a hole drilled by said drill tip, and wherein successive segments of the sheath are configured to assume a predefined deflected position relative to adjacent segments when projecting beyond the outer conduit, but are limited to a straightened configuration within the outer conduit, such that, when a portion of the sheath is advanced relative to the outer conduit so as to extend beyond the outer conduit, the drill tip advances together with said portion of the sheath so as to drill the hole along a curved pathway.
