摘要: An end effector assembly for an optical surgical instrument includes a jaw member and a plurality of optical elements positioned within a cavity of the jaw member. The jaw member has a tissue contacting surface. The jaw member has a proximal portion that is configured to secure a fiber optic cable thereto such that a distal end of the fiber optical cable extends into the cavity. The plurality of optical elements are arranged in a staircase-like manner that rises towards the tissue contacting surface as the plurality of optical elements extends distally within the cavity. The plurality of optical elements is configured to direct a beam of light exiting the fiber optic cable towards the tissue contacting surface.

摘要: Methods and systems for surfactant enhanced laser-induced vapor bubbles for use in laser lithotripsy. Urinary tract stone disease is a common and costly disease that effects approximately 10% of the United States population. A preferred minimally invasive method for treatment of urinary tract stones is laser lithotripsy, which involves insertion of a flexible ureteroscope through the urinary tract to the stone's location, and then transmission of infrared (IR) laser energy through a flexible optical fiber, which is in turn placed through the single working channel of the ureteroscope. The IR laser energy is used for ablation of the urinary tract stone which is then removed. In order to have a more efficient ablation, the ureteroscope is fed with a surfactant composition which is flowed into the ureter and/or kidney of the subject. The laser causes larger bubbles to form in the surfactant composition, making a robust and longer lasting bubble.
