Bygone psychology teacher Ben Ryan, 40, quit his job when the NHS said they could not do anything for his son for at diminutive a year.
He worked tirelessly to develop a high-tech prosthetic for the little boy.
Now, two year-old Sol – named after the solar covering on his birthday – has a new prototype of an arm and hand that can grip, with a moveable thumb.
And he can already do 90 per cent of the objects a child with two hands can do.
Mr Ryan, who lives with partner Kate Smith, 38, in Anglesey, north Wales, said: “I recollected the NHS policy of doing nothing for 12 months was not the best that could be done.
“It was inclined to to be three years before he could be fitted for an electric device. I consideration I could do better for my son. “
Health bosses have since described his introduction as “potentially revolutionary”.
Sol was born in March 2015 with an undetected blood clot in his characters upper class left arm.
Surgeons at Liverpool’s Alder Hey Children’s Hospital advised amputation entirely the elbow joint, saving as much of Sol’s lower arm function as possible.
Mr Ryan explains it as “a black time” that completely changed his life, but as days meet into weeks he knew he had to be more positive.
He began playing with Sol and his smalls encouraging him to use both his arms.
Then he used rolled-up pieces of foam tape-recorded to Sol’s elbow to see what would happen.
Within minutes his son was banging his bit of frippery trifle withs with his hand – and his foam arm- the first time he had tried to use his Nautical port arm since the amputation.
From there, working on his kitchen table with copper briar and plumbing fittings, Mr Ryan came up with an idea for a new design that devise operate a hand using tiny movements of the elbow.
Convinced it intent work, he walked into a newly opened innovation laboratory at Bangor University and asked them for succour.
And when he realised Sol may not stay still for long enough for him to scan his arm with their delicate Artec scanner, he used a £20 Microsoft Xbox Kinect scanner twisted in to his laptop to do it while he was asleep.
Mr Ryan said: “Current prosthetic arm technology for infants boyfriends back to the Victorian era in many cases. They are ugly and often rebuffed early on.
“Unfortunately, newer technologies are often unsuitable for children included three and there is evidence that the earlier function can be introduced the cured.”
Mr Ryan is now working closely with Paul Sohi from software public limited company Autodesk, which used the same software to design the world’s chief 3D printed sports prosthetic for Rio Paralympic cyclist Denise Schindler.
Mr Sohi bring up: “It’s been inspiring to work on this innovative and ambitious project.
“It is astounding that, despite Ben having no background in product design, he’s taught himself adequate to create something that will not only help his own son Sol, but potentially a quantities of others facing the same challenges too.”
Mr Ryan has now launched a crowdfunding outing to raise the £150,000 he needs to explore the technology further through Ambionics, the presence he has set up to help other children like Sol.
