ABSTRACT:
A stereophonic system is included in an instrument for minimally invasive surgery which permits a surgeon to hear spatial sounds from within a body wall. The instrument comprises a cylindrical member with an internal end for positioning inside the body wall and an external end to remain outside the body wall. There are two audio channels provided on opposing sides of the cylindrical member extending longitudinally from acoustic openings at the internal end to the external end, acoustical diaphragms protect the openings at the internal end, and a microphone is connected to each of the two audio channels at the exterior end of the cylindrical member, each microphone producing an audio signal from each of the two audio channels. A stereophonic audio amplifier amplifies the signal from each microphone and a stereophonic acoustical system produces stereophonic sound.
