Stone sense with fiber erosion protection and camera saturation prevention, and/or absence-detection safety interlock
A system and method for detecting relative location of a surgical laser fiber tip relative to a surgical laser target during a surgical laser procedure utilizes a spectrophotometer to detect radiation indicative of the relative location. For example, the detected radiation may indicate contact between the fiber tip and a stone being subjected to laser lithotripsy, so as to prompt the surgeon to withdraw the fiber tip from the stone and / or take other action to limit contact-induced erosion of the fiber tip, and to avoid saturation of the endoscope camera resulting from the flash that occurs following contact. In addition, the absence of any detected radiation by the spectrophotometer may be used to indicate that the stone is no longer present, or that the fiber tip is no longer aimed at the stone, prompting the operator to reposition the fiber and / or temporarily cease firing of the laser. The main surgical laser may be a pulsed Holmium laser, which is delivered to the target through the optical fiber together with a pulsed 532 nm aiming beam.
