Advice on med tech. ! The manuals.

Hello Doctors, I am a school student participating in vivo ignite tech nation wide competition. Actually, I really didn't had any option to go out and look for information so I searched online and landed up here.! Actually, I am already a student who dreams to be in med-world but that's a long way ahead. Before only I got to know about this competition and I am currently thinking of developing something related to med tech. As you know world is evolving so is technology. I thought of some dental devices or something to help on with surgery or reduce muscle strain for your exhausting working hours.I also thought of hand tremors for surgery efficiency. I wonder if you could help me with the ideas.If you can please do tell me what's the most tiring thing in your routine or something that strains you up so much.The more the consents the better, because only with variety I can come up with a better and best idea.I hope you can help me as I don't have much time to submit the manuals.Thanku.
