HANDHELD LAPAROSCOPIC ULTRASOUND DOPPLER STETHOSCOPE

摘要

A handheld battery operated laparoscopic ultrasound doppler stethoscope (1) having a body member (2) containing electronics for generating and transmitting ultrasound signals at a predetermined frequency and for processing doppler shifted return signals, a doppler probe (3) which comprises an elongated rigid tubular member (5) having at one end thereof an ultrasound transducer (6) for transmitting and receiving ultrasound signals, the elongated rigid tubular member having an outside diameter small enough to permit the elongated rigid tubular member (6) to fit within the bore of a laparoscopic tube and a length which exceeds the length of the laparoscopic tube by a predetermined distance, the stethoscope including a male and a female jack (9, 8) for removably attaching the doppler probe and the transducer therein to the electronics in the body member.
