Detector for surgical source of bleeding, has Doppler sonographic head locating intra-operative source of bleeding, and ultrasonic generator transmitting low- and high-frequency signals, respectively, for venous and arterial bleeding

摘要

The detector has a sterile protected Doppler sonographic head adapted to locate intra-operative source of bleeding by the maximum of bleeding-conditioned reflection. An ultrasonic generator transmits a low frequency signal for venous bleeding and a high frequency signal for arterial bleeding. The head is formed in such a manner that the head is adapted to press the lesion of the vascular system based on the operation condition.
