Abstract

A single-use or reusable cap or an objective head to a scope can be used for integrating a laser fiber within the objective head but outside a working channel of the scope. The endoscope maintains an attached or embedded permanent laser fiber to ablate particulates that are suctioned into the endoscope assembly via a suction conduit.

Abstract

In an optical detection device, such as an endoscope, a detector having a controllable detector integration time can generate a detector signal from light that is reflected or emitted by a sample and collected by a user-replaceable optical fiber. A spectrum analyzer can measure a. spectrum of the detector signal. A controller can receive fiber parameter data that corresponds to at least one value of at least one physical parameter, such as core diameter, of the user-replaceable optical fiber. In response to receiving the fiber parameter data, the controller can establish or adjust the controllable detector integration time to have a value that corresponds to the at least one value of the at least one physical parameter of the user-replaceable optical fiber. For example, the controller can decrease the controllable detector integration time value with increasing diameter of the core of the user-replaceable optical fiber.

Abstract

Laser lithotripsy systems and methods with a controlled retropulsion setting to facilitate manipulation, migration, and ablation of a calculi structure are disclosed. An endoscopic lithotripsy system comprises a laser system to provide laser pulses to a calculi structure in an anatomical environment, and a controller circuit to localize the calculi structure. If it is determined that the calculi structure is not at a target location, the laser system emits first laser pulses according to a first laser output setting, which produces a high retropulsion effect to mobilize and reposition the calculi structure to the target location. For calculi structure located at or migrating to the target location, the laser system emits second laser pulses according to a second laser output setting, which produces a lower retropulsion effect than the first laser pulses, but a higher efficiency to ablate or fragment the calculi structure.
