HS waiting lists reached a staggering 7.75 million last October, with forecasts suggesting
this figure could rise to eight million patients by the summer. To alleviate some of the challenges faced by the NHS, the Government has introduced the Innovative Devices Access Pathway (IDAP) pilot. Backed by £10 million of Government funding, the IDAP will provide medical device designers and manufacturers with specialist guidance in order to accelerate their product through regulatory processes. Ultimately, the initiative aims to support rapid development of new technologies for eventual widespread adoption in the NHS. So, what can we anticipate for the future?
Robotic surgery has been found to offer huge benefits
continuously working on scans will also get more accurate over time, potentially enabling earlier detection of disease. Surgical robotics might also see a similar breakthrough. Robotic surgery has been found to offer huge benefits, including improved safety and a recovery time shortened by up to 20%. Despite this, there’s still little available data on the presence of medical robotics in the UK. One study published back in 2020 counted just 61 robots across 48 NHS trusts, out of 149 that participated in the study.
In the future, we’re likely to see growing implementation of AI. AI could, for example, play a vital role in streamlining medical imaging, providing a second medical opinion without the time requirement of an additional person. Plus, an AI
For manufacturers who are looking to develop the next generation of medical devices, there’s a lot at stake – few other sectors require a level of life-or-death precision. As a result, design engineers must ensure that all hardware meets desired requirements of safety, accuracy and longevity. Every single component must be scrutinised to ensure it is fit for purpose. Any medical device that features some level of automation or
motorisation will require a drive system to provide the necessary movement, whether it’s a multi-leaf collimator focusing a radiotherapy beam or an infusion pump delivering precision doses over time. Looking into the drive system itself reveals a variety of different
components. This typically includes one or more DC motors, which are vital in providing the necessary movement. Developments in DC motor technology offer new levels of performance, with high torques and control available from ever-decreasing sizes. Brushless DC motors are a popular choice, offering a high torque
to weight ratio and operating efficiency. Their lack of brushes means reduced wear and an extended service lifetime, ideal for the continuous operation required for many medical applications. It also means a reduction in vibration and noise, offering greater patient comfort. Depending on the exact requirements of the application, it’s possible
to customise the performance of the drive system further with the addition of other components. Applications requiring high positioning accuracy, for example, might benefit from the inclusion of an encoder. Encoders can provide precise feedback on the motor’s positioning, allowing for adjustments to be made accordingly. Other potential inclusions are the use of precision gearheads, as well as motion and speed controllers. As the UK turns
to technology to transform its healthcare services, designers and manufacturers must play their part. Engineering medical devices for the future is no mean feat, but taking advantage of the latest in electronics brings developers – and patients – one step closer to a healthier future.
