PUNCTURE OPERATION SUPPORT SYSTEM

PROBLEM TO BE SOLVED: To provide a puncture operation support system allowing the appropriate penetration depth of a puncture needle to be recognized by voice signals from the right and left of earphones put in both ears, offering excellent responsiveness of the voice signals for the penetration depth of the puncture needle in spite of a simple structure, and permitting puncture operation while looking at an ultrasonic diagnostic image on a monitor mounted in front of the eyes.SOLUTION: The puncture operation support system includes a sensor for measuring the penetration depth of the puncture needle, and a sine wave oscillation means for converting the signals measured based on the sensor into sine waves to oscillate. Voices obtained by allowing the output sine waves to pass through the high-pass filter side of a combination of a high-pass filter and a low-pass filter of substantially the same cutoff frequency are output to one earphone of the right and left earphones, and the voices that have passed through the low-pass filter side are output to the other earphone to sense the optimum penetration depth by the voice signals.
