Development of a Handheld Scanner for Completion of Surgery in a Hospital Theater
Authors: Oduah UI, Folarin ST
This research developed a novel handheld surgery completion scanner, an electronic device constructed to be used in a Hospital Theater for detecting forgotten surgical instruments in humans and animals during and after a surgery. This device uses the beat frequency oscillator technology in carrying out the scanning activity, and has a speaker for delivering its output. It beeps immediately a metal surgical instrument is detected. This innovative device functions with the principles of a metal detector, which uses the pulse electromagnetic induction to detect metals. The electromagnetic field is generated with the aid of a coil wrapped on a cylindrical ferrite rod and does not pose any health hazards to the patient. The radiation is generally safe to the body organs. This device is focused on eliminating the rising life risks associated with several reported cases of patients being stitched with surgical instruments forgotten inside their body. The inclusion of this device as part of completion exercise for every surgery will eliminate the possibility of forgetting any instrument in the body. The designed and constructed handheld surgery scanner is portable, cheap, easy to operate, and safe for both the patient and health workers. It is a welcome development in all hospitals worldwide.
