Sophisticated application of magnetic force enhances laparoscopic surgery
A tissue-moving instrument controlled by magnets could improve minimally
invasive surgery, say the Vanderbilt University engineers who are developing
it.
The device consists of two units, a thin rod-shaped part that can be inserted through a small incision typically made for laparoscopic surgeries and an external controller. Both contain two sets of magnets, one that pairs them together through the abdominal wall, and another that allows the surgeon to operate the internal unit’s machinery.
What are the advantages over the current technique of inserting a surgical tool attached to a stick through an incision?
Well, since the internal unit isn’t connected to the outside by a rigid stick, it can be moved into a number of more useful positions. And since the internal unit houses machinery actuated by magnets instead of miniaturize electric motors, it can deliver up to 100 times greater mechanical power than current technology.
