Outline of Final Research Achievements

We tried to structure the gauze detection system before closing a surgical incision, which can detect remnant gauze outside the body in a short time even if it remains inside the body during surgery. We found remnant gauze while creating several types of gauze detection devices and gauze for detection and detecting a metallic fiber included in the gauze for detection. By the past improvement of the gauze detection system before closing a surgical incision, gauze for detection can be now detected about 30cm away from it even though the detection distance was about 10cm when we initially started this study. We cannot specify the position of the remnant gauze by image still now however we created a prototype of gauze detection device, which appeals to visual and auditory senses at the same time.
