problem with designing serious game

Dear Madam/Sir,

I am Nahid Sharifzadeh, master student of Medical Informatics at Mashhad University of Medical Sciences, Iran. I am working on designing and developing a game for residents (physicians) as my master thesis. The purpose of this game is for learning surgery to residents rather than for fun.The following link resembles my game:

I would be thankful if you let me know what training I should receive to fulfill my thesis. If there is any helpful website? if so, please let me know the link.

Best Regards,
Nahid Sharifzadeh

Thank you for your answers.

I tried to find a package from unity website for picking an object, but I didn’t find. I want a package in which tools are selectable, and include a hand that can pick tools up and use them.
I downloaded various training, but non was helpful. @Gobaz

I am professional in 3dmax and Photoshop, as well as some graphical softwares. However, it is the first time I work by unity. I also fairly know programming (writing codes), but I have not been doing programming for unity media.
At the moment, I intend to learn designing 2D games. My problem is that I don’t know exactly how I should make to move an object by moving mouse and trigger the object by mouse clicking, in other words I want a hand tool to pick an object up by the mouse. @tanoshimi

In fact, YouTube is a pull of many different videos, so that I confuse to select them to watch and use. @Owen Reynolds
