Nikolai Begg: A tool to fix one of the most dangerous moments in surgery



Surgeons are required every day to puncture human skin before procedures — with the risk of damaging what’s on the other side. In a fascinating talk, find out how mechanical engineer Nikolai Begg is using physics to update an important medical device, called the trocar, and improve one of the most dangerous moments in many common surgeries.

  • Embalming involves the use of trocars too. In either through the armpit,or groin.

  • READ THIS ONE: I'm sorry I couldn't help it.  I'm a general surgeon, and the information presented here is almost obsolete in the US.  Bladed trochars with springs were a great idea, but they were out over 10 years ago.  I have never used or seen someone use a sharp trochar before, as there are safer methods.  The 2 most common: 1) an optical trochar that allows the camera to be placed through and watch each layer be separated until safely inside the abdomen.  2) a small open incision into which a blunt trochar is placed under direct vision.  There are risks to every surgery performed, and injuries still occur, but they are certainly less than 0.1%.  I love TED talks, but it goes without saying, don't believe everything on the internet is true or up to date.

  • Trocars are awesome. What he might not understand is that specially made trocars actually are much more controlled than what he saw.

  • There could be a problem with skin though. If pressing down and there's no space in between the skin and lets say the bone or organ underneath it will not know the difference. Think of it like this, if it pierces the skin with something right beneath it, there will still be opposite force keeping it locked. It's still a better system and you'd have to be careless to put enough force into the skin to have this accident.
