The Future of Needles
Needles that we use today have existed in this form for thousands of years. According to Jeffrey karp, Professor of chemical and bioengineering at the Hardev-MIT Division of Health Science and Technology, there is a new design that will upgrade and automate the medical tool.
Generally, when inserting needles, doctors and nurse rely on tactile feedback. This clinical skill takes years to master. Essentially, the new needle works like a simple clutch, in a car. This needle is S-shaped with a bendable piece of metal or plastic inside it. While the needle is strong enough to progress through tougher tissue like of muscle, the filament bends back inside the needle. When it hits the target, the filament is fully pressed against the outside of the needle and locks in place, like an engaged clutch. At that point, the niddle and its filament move togethr. But when the device finally reaches the spot ," be it lung , stomach or blood vessel," the clutch disengages. The pressure is off the filament and it releases into the filament and it releases into the target area, and its rounded tip prevents it from breaking through the other side.
Doctors accidentally puncture the subarachnoid space of the central nervous system several thousand times every year. That's why it is critical that the new needle's clutch knows when to stop, releasing on its own and entering the low-pressure target area.
