Endoscope laser system with laser interlocking device

Systems, devices, and methods for determining advancement of a surgical laser fiber in an endoscope and providing interlock feedback for the surgical laser are disclosed. An exemplary method includes directing light from a distal end of an endoscope to a target; optically detecting an amount of light reflected from the target; transmitting the optically detected amount of light through a laser fiber extending through a working channel of the endoscope; determining a position of the distal end of the laser fiber relative to the distal end of the endoscope based on the optically detected amount of light; and generating a control signal for the surgical laser system to adjust the laser emission through the laser fiber. 公开了用于确定内窥镜中的手术激光光纤的前进并为手术激光提供互锁反馈的系统、装置和方法。示例性方法包括：将光从内窥镜的远端引导至目标；光学地检测从目标反射的光的量；通过延伸穿过内窥镜的工作通道的激光光纤来传输光学地检测到的光的量；基于光学地检测到的光的量来确定激光光纤的远端相对于内窥镜的远端的位置；以及生成针对手术激光系统的控制信号以调整通过激光光纤的激光发射。
