摘要： A laser tissue ablation system can include an optical fiber, with a distal end being extendible from an endoscope body of an endoscope. The optical fiber can deliver therapeutic laser light from the distal end of the optical fiber toward a target site, and receive return light into the distal end of the optical fiber. The laser tissue ablation system can include a sensor that can spectrally measure the return light. The laser tissue ablation system can include processor circuitry that can form a first determination, from the spectral measurement of the return light, whether flashing event light is present in the return light. The flashing event light can be generated when a flashing event occurs at the distal end of the optical fiber. The processor circuitry can generate, in response to the first determination, a flashing event data signal that indicates whether the flashing event has occurred.

摘要： Various examples disclosed relate to temperature monitoring of medical probes. The present disclosure includes a medical device including a medical probe and one or more luminescent marks. The medical probe can include a distal portion configured for at least partial insertion into a patient. The one or more luminescent marks can be located on the distal portion of the probe and have a luminescent characteristic correlative to temperature, when illuminated. The luminescent characteristic can provide an indication of the temperature at an internal site of the patient.

摘要： Systems, devices, and methods for delivering laser energy to a target in an endoscopic procedure are disclosed. An exemplary method comprises providing a first laser pulse train and a different second laser pulse train emitting from a distal end of an endoscope and incident on a target. The first laser pulse train has a first laser energy level, and the second laser pulse train has a second laser energy level higher than the first laser energy level. In an example, the first laser pulse train is used to form cracks on a surface of a calculi structure, and the second laser pulse train causes fragmentation of the calculi structure after the cracks are formed.

摘要： Systems, devices, and methods for determining advancement of a surgical laser fiber in an endoscope and providing interlocking 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 the 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, based on the optically detected amount of light, a position of a distal end of the laser fiber relative to the distal end of the endoscope, and generating a control signal to the surgical laser system to adjust laser emission through the laser fiber.

摘要： Systems, devices, and methods for identifying a target in a body using a spectroscopic feedback from the target are disclosed. An exemplary surgical feedback control system comprises a feedback analyzer configured to receive a reflected signal from a target in response to electromagnetic radiation directed at a target, and a controller in operative communication with the feedback analyzer. The controller can generate a control signal to a surgical system to perform a predetermined operation based upon the received reflected signal, including determining a composition of the target, or programming a laser setting to direct laser energy to the target.

摘要： Systems, devices, and methods for identifying a target during an endoscopic procedure are disclosed. An endoscopic target identification system includes an endoscope having an endoscopic illumination source, an optical fiber insertable through a working channel of the endoscope and coupled to a non-endoscopic illumination source different from the endoscopic illumination source, and a controller. The controller can send a control signal to the non-endoscopic illumination source to emit a diagnostic beam through the optical fiber when the at least one endoscopic illumination source changes from a first mode to a second mode. The second mode has a lower amount of illumination than the first mode. The controller can determine a composition of a target based on the diagnostic beam incident on the target and light from the diagnostic beam being reflected from the target.
