Engineering controls for surgical smoke in laser medical handpieces

The hazard of surgical smoke is often overlooked when considering the safety medical laser procedures but can present a high level occupational risk. Administrative for operating external extraction devices and reliance on personal protective equipment are not sufficient reducing This paper aims to quantify laser-generated demonstrate how effective engineering control solutions reduce A new design solution presented with controls optical radiation integrated into handpiece. fiber delivered diode used simulate vaporization porcine skin tissue. Conventional conditions compared solution. Fine particulate mass concentrations (PM2.5) from simulated procedures, under different conditions, measured using particle size measurements. Peak 55.86 ± 2.79 ?g/m3 were without extraction; showing that five times greater than World Health Organization guideline 10 ?g/m3. typical setup only achieved 16% reduction in peak concentration values, 47.07 2.35 ?g/m3; demonstrating conventional, external, methods ineffective. was able capture all materials, background levels, 2.19 0.68 ?g/m3, safely below current recommended guidelines. results evidence it more use practicable do so.
