?:definition
  • Equipment designed for the endoscopic ligation of rectal hemorrhoids using ultrasound as a guide for the location of arteries. These devices consist of an electronic unit connected to a dedicated anoscope that includes a Doppler ultrasonic transducer and an integral needle for artery ligation (typically using an absorbable suture), a fiberoptic illumination system, and a display. Ultrasound-guided rectal hemorrhoid ligation units are intended to facilitate the location of arteries that supply blood to hemorrhoids and to provide a more accurate and repeatable means of hemorrhoid ligation.
