Laser ablation surgery system with safety control of temperature and pressure at surgical site and method of use

A laser ablation surgery system with safety control of surgical site temperature, the system comprising:

• (a) a laser source configured to produce a laser beam at a wavelength absorbable by an ablation target through a laser fiber connected thereto;
• (b) an endoscope having one or more lumens with at least one lumen configured to feed an irrigation fluid therethrough and having at least one temperature sensor disposed at a distal end of the endoscope, the temperature sensor being configured to monitor a temperature of the irrigation fluid at a surgical site of a laser ablation surgery in real time;
• and
• (c) a system control operably connected to the at least one temperature sensor, the system control comprising a patient injury risk calculator configured to perform a real time thermal injury assessment utilizing the temperature of the irrigation fluid at the surgical site detected by the at least one temperature sensor during the laser ablation surgery;
• and
• wherein the patient injury risk calculator is configured to further perform a preoperative thermal injury risk assessment and generate a preoperative thermal safety guideline for a selected laser ablation procedure.

A method of laser ablation surgery comprising:

• (a) performing a laser ablation surgery on an ablation target using a laser ablation surgery system, said system comprising:
• (i) a laser source configured to produce a laser beam at a wavelength absorbable by the ablation target through a laser fiber connected thereto;
• (ii) an endoscope having one or more lumens with at least one lumen configured to feed an irrigation fluid therethrough and having at least one temperature sensor disposed at a distal end of the endoscope, the temperature sensor being configured to monitor a temperature of the irrigation fluid at a surgical site of a laser ablation surgery in real time;
• and
• (iii) a system control operably connected to the at least one temperature sensor, the system control comprising an intraoperative surgical patient injury risk calculator that generates a patient injury risk score based on a patient injury calculation risk model that combines a plurality of weighted risk factors to generate the patient injury risk score, where each weighted risk factor includes a particular patient injury risk factor that has a value within a predetermined scale to indicate a level of patient injury risk associated with the particular patient injury risk factor and further includes a weight value which is applied to the particular patient injury risk factor according to an importance of the particular weighted risk factor to an overall calculation of the patient injury risk score, and wherein the intraoperative surgical patient injury risk calculator is configured to calculate a real time patient thermal injury risk score based on the patient injury calculation risk model which combines the plurality of the weighted risk factors to generate the real time patient thermal injury risk score, and wherein one of the weighted risk factors being associated with the temperature of the irrigation fluid at the surgical site detected by the at least one temperature sensor during the laser ablation surgery;
• and
• (b) monitoring the temperature of the irrigation fluid at the surgical site during the laser ablation surgery by the at least one temperature sensor, wherein the intraoperative surgical patient injury risk calculator calculates the real time patient thermal injury risk score based on the temperature of the irrigation fluid at the surgical site detected by the at least one temperature sensor during the laser ablation surgery.
