British start-up Touch Surgery, which uses VR headsets to train doctors, has secured $70m (£54m) in funding to grow its product line, according to a report in The Daily Telegraph.

The British newspaper said the company, who had previously raised $19.5 million from U.S. venture capital fund 8VC, secured the money in October. It did not say where from. Touch Surgery did not respond to requests for comment from Halldale. Touch Surgery's main backers are in Silicon Valley.

Surgeons Dr Jean Nehme and Dr Andre Chow set up the company in 2013. Its technology allows doctors to use headsets to study and review simulated operations. This means an experienced surgeon can help colleagues remotely and achieve best practice more widely.

Its app, which has been downloaded 2.5 million, offers virtual tutorials of more than 160 procedures. It also provides a chance to test your expertise.

In addition, the start-up provides video and data analysis systems for hospitals, working with the NHS.

The Daily Telegraph said Touch were offering its services to U.K. and U.S. hospitals.
