Adaptive Optical Laser Beam Steering Through Endoscope for Laser Surgery in Kidney
This invention introduces an apparatus for precisely steering a laser beam through an endoscope, specifically designed for laser surgery within the kidney. Its most significant advantage lies in its ability to apply adaptive optics to deliver a highly focused laser beam to a selected target location, enhancing surgical precision and efficacy.
Description
The core of this technology is an apparatus featuring a spatial light modulator (SLM) that receives an input optical beam. An SLM controller adjusts the SLM to apply a phase modulation to the input beam, producing an "adapted optical beam." This adapted beam is then directed into a fiber bundle, emerging from its distal end as a focused beam aimed at a target. The system also includes a detector that receives portions of the laser beam reflected back from the target. Crucially, the phase modulation applied by the SLM is iteratively determined based on the amplitude of the received reflected light, ensuring precise focusing and direction of the laser beam. This adaptive process allows for accurate targeting, even in complex environments like within a kidney. The apparatus may also include a channel adjacent to the fiber bundle for fluid delivery to the target, and a laser system to produce the input optical beam.Applications
