Laser surgery system with safety control of non-target tissue temperature and method of use

摘要

A laser ablation surgery system with a safety control of non-target tissue temperature and laser ablation surgery method are provided. The system includes a laser source configured to produce a laser beam at a wavelength absorbable by a target issue through an optical fiber connected thereto, a temperature sensor disposed at an irrigation fluid outlet of a flow sheath of a continuous flow endoscope, and a system control operably connected to the laser source and the temperature sensor. The temperature sensor is configured to monitor the temperature of an effluent exiting a body cavity adjacent to the target issue during a laser ablation surgery. The system control includes at least one predetermined effluent temperature threshold and a laser control mechanism. The system control is configured to activate the laser control mechanism when the temperature sensor senses the temperature of the effluent exceeding the predetermined effluent temperature threshold.
