Micro Drives Increase Surgical Precision

Medical surgical robots will change the face of surgery in the future.
Miniature medical actuator systems used in minimally invasive surgery need to be as compact as possible.
These miniature medical actuator systems will definitely be of help in applications where there is a need for precise positioning.

The advantages of medical minaturization are obvious. What I still don't get is how telemedicine. which in terms of its technological heritage is certainly related, is widely applicable. It can work in certain situations but what happens when something goes wrong? An unexpected emergency (bleeding out), power outage, or some physical movement which takes the patient out of the operational window (like falling off the operating table; I guess that's why they strap you down).

Well, that does make telemedicine sound scary. AFAIK, hospitals have long been one of the biggest users of massive, high end UPS systems, at least since the early 80s when I worked in the UPS industry. OTOH, when the Northridge quake struck L.A., Santa Monica Hospital lost electricity and a lot of people got hurt.

I don’t understand why batteries are needed-?

I understand the surgical aspect of these small motors but I'm missing the point as to why they are advancing developments of such surgical tools with batteries.  Maybe not for the surgical tools, but for post surgical implants-?  Guessing batteries would be needed for a prosthetic, perhaps where tiny motors move finger joints?  But I'm not clearly envisioning the application.  It's different from say, a pace-maker with a 5 year battery sending a micro-pulse to a heart muscle – no moving parts in that App.  -- So, why batteries-?

Motor sizes

It's easy to read through this article and skim right past one amazing bit of information: "Motor sizes of 1.9 mm in diameter..." That's a motor diameter of about 1/12th of an inch! I'd be curious to see how a motor of that size is manufacturerd.

Telemedicine must be seen from a different angle I guess rather different scenarios. In a country like India or some part of Africa where there are many villages without even a primary health centre, leave alone speciality hospitals. But if one can set up a telemedicine centre, it will make the necessary medical services available to the needy. Well that does not take away the risks involved in telemedicine procedures but it is better than that of the scenario where there is no medical service at all.

Motion Miniaturization

There are a variety of motion suppliers that are providing miniaturization solutions at different levels which are being implemented in medical applications.  This is one of the exciting areas for motion development.  Some piezo technology solutions are integrating micro-mechatronic modules (combining controls, drives, sensors) that are ideal for use in medical devices, robotic surgical tools and precision analytical instrumentation. It also can be used to create non-magnetic motion systems for safe operation in MRI environments.

Latest Analysis
Lithium-ion battery prices will drop rapidly over the next 10 years, setting the stage for plug-in vehicles to reach 5%-10% of total automotive sales by the mid- to late-2020s, according to a new study.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
The big picture to this hands-on technology curriculum is to illustrate to students that the future of IoT and IoE (Internet of Everything) development can be created in today’s classroom.
A recent Design News-exclusive study proves that engineering professionals are at the very forefront of this push into the future and making direct financial, performance, and value impact on their organizations by being personally involved or final decision-makers on automation solution and component choices.
