摘要： A light beam guided liquid delivery device, including: a liquid delivery device; a light beam generator; and a bracket coupling the light beam generator to the liquid delivery device such that a beam of light is selectively delivered approximate to a tip of the liquid delivery device. The bracket couples the light beam generator to the liquid delivery device at a first attachment point. The bracket includes one or more hinges at the first attachment point for varying the orientation of the light beam generator. Optionally, the bracket also couples the light beam generator to the liquid delivery device at a second contact point. The bracket includes a support member at the second contact point for varying the orientation of the light beam generator. Optionally, the support member is translatable with respect to the one or more hinges along a length of the bracket.
