DEVICE, SYSTEM AND METHOD FOR PROVIDING LASER STEERING AND FOCUSING FOR INCISION, EXCISION, AND ABLATION OF TISSUE IN MINIMALLY-INVASIVE SURGERY

摘要

PROBLEM TO BE SOLVED: To provide a device and a system for use in laser steering and focusing for incision, excision and ablation of a tissue in a minimally-invasive surgery.SOLUTION: A structure which is configured to be inserted into a body 902 of an endoscope laser scalpel device 901, includes optical elements 907 and 908 capable of constituting refracted light and/or diffracted light. One of the optical elements is configured to receive the at least one light at one first angle, and generate at least one refracted or diffracted light at a second angle which is different from the first angle relative to an optical axis. An actuating arrangement 906 configured to control the at least one optical element is situated partially within the structure.SELECTED DRAWING: Figure 9B
