Looking for a brand-new technique
Because the needle shed in the child's situation was actually made from ferromagnetic product (steel), our team utilized magnetic sensing units ( magnetometers ) initially meant for biomagnetism research researches - referred to as SQUIDs - efficient in spotting extremely weaker magnetic areas. Therefore, our team dealt with establishing a localization technique that had the ability to determine the object's precise setting in the body system in 3 measurements: deepness, positioning, as well as facility. These specifications were actually utilized in mix along with the forecast of the international body system on the skin layer towards strategy the treatment as well as specify the medical incision.
The outcome was actually incredibly motivating. Besides assisting that kid, our team later on experimentally validated this method in 6 various other situations of effective elimination of shed stitching needles coming from other individuals. In each situations, it was actually feasible towards precisely find the items, considerably decreasing medical opportunity as well as guaranteeing the excellence of the elimination treatment.
This expertise was actually therefore considerable that it specified our scholastic course. Our team remain to go after this subject as among our research study locations towards today, as scientists at the Biometrology Lab (LaBioMet) at PUC-Rio - along with sustain coming from FAPERJ , CNPq , CAPES , as well as FINEP.
Eventually, certainly there certainly was actually still a lot towards enhance. In spite of the higher precision of our method, the sensing unit had to run at extremely reduced temperature levels, that made the devices costly, complicated towards run, as well as challenging towards produce. This eventually avoided its own extensive fostering as a biomedical gadget.

After that, a couple of years later on, brand-brand new magnetometers based upon the titan magnetoimpedance (GMI) sensation arised. These are actually extremely delicate, inexpensive sensing units efficient in running at space temperature level. Therefore, in 2008, our team adjusted a brand-new model using this brand-brand new innovation for clinical requests.
