发明名称 Dual doppler artery ligation and hemorrhoid treatment system
摘要 A dual Doppler artery ligation and hemorrhoid treatment system has a probe. The probe has a disposable cylinder with a cone-shaped cap at the distal end and a support adjacent to the proximal end. A series of white light emitting diodes is mounted within the support. The support has a backing plate proximally and an opening to the cylinder and cone distally. The cylinder has an opening adjacent to its distal end and a pair of ultrasonic transducers secured on the cylinder laterally spaced on the center line proximal side of the opening. An echo analyzer is operatively coupled to the probe and is adapted to emit signals and to detect and analyze received signals as a function of the blood flow there adjacent to produce an output which varies as a function of the arterial blood flow of a hemorrhoid extending through the aperture.
