ABSTRACT：Excesive hemorhage and irigation fluidabsorption during endoscopic surgery maycause severe complications， whiletraditional monitoring methodsare inaccurateand invasive.To addresssuch problems，our research team jointly developed with industry partnersan endoscopicsurgery monitoring system employing multisensor fusion technique.This system achieves dynamic bloodlossquantificationthroughphotoelectric measurementof hemoglobinconcentration ineffluentfluidand preciselycalculates irigationabsorptionusingstrain-gaugesensors withurine-compensationalgorithmsbasedonvolume-balance principles，integrated with real-time threshold alerts. Validation confirms measurement errors ⩽±4% for hemorrhage and ⩽±2% irrigation fluid for absorption.Clinical applications in transurethral resectionof the prostate（TURP），percutaneous nephrolithotomy（PCNL），and hysteroscopic surgeries demonstrate highacuracyand stability.Thesystem efectively enhances surgicalsafetyby preventing TURPsyndrome，urinarytract infections，and majorhemorrhage，showing significantclinical translational value.
