Although miniaturisation brings clear benefits for patients and clinicians, it also introduces mechanical constraints that can influence how reliably these devices perform with time.  

Here, Chris Johnson, Managing Director of bearing specialist, SMB Bearings, explores how mechanical decisions that once seemed secondary can begin to dictate overall product success. 

In emergency care settings, smaller equipment can be transported directly to the patient, reducing delays when time is critical.

The NHS’s continued investment in robotic surgery reflects this trend, with NHS England projecting that robotic systems could support up to 500,000 procedures per year by 2035, highlighting a growing demand for compact and flexible technologies.
