Miniature medical actuator systems used in minimally invasive surgery need to be as compact as possible. Micro drives are an effective solution because they offer high performance from small packages, are easy to control, and help increase the fingertip sensitivity of the surgeon.
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.
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.
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.
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.
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-?
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).
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.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
UK researchers have come up with a method for machining aerospace-grade, carbon fiber-reinforced composites, along with high-strength aerospace alloys, using an ultrasonically assisted machining device. It also works on high-strength aerospace alloys.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
