This YT727 980nm + 1470nm dual-wavelength diode laser therapeutic machine is mainly for minimally invasive proctology treatment, which can precisely treat hemorrhoids, fistula, fissure, pilonidal sinus and other anorectal diseases. It is equipped with an LCD screen, emergency stop switch, optical fiber connector and various treatment probes (radial fiber, conical fiber, anoscope). It supports three working modes: CW, Pulse and Single, with adjustable energy, time, pulse delay and other parameters.The 980nm wavelength has strong absorption for hemoglobin, while the 1470nm wavelength has high absorption for tissue water. Paired with radial fiber, it achieves intraluminal photothermal occlusion with minimal trauma, high precision, and effective protection of mucosa and sphincter, reducing postoperative adverse reactions. The device supports wide voltage (100-240V), compact and portable, suitable for clinical minimally invasive anorectal treatment.
