HOW DO TELESURGERY WORK?
TELESURGERY

In recent years, due to the health emergency, scientific innovations in health have become part of everyday life, and are increasingly present in all medical areas. Despite its widespread use, the use of technologies continues to be the subject of study and constant research.

Among these innovations, without a doubt, the one that continues to constantly evolve is telemedicine. The use of ICTs (or communication technologies) for consultations and treatments, including apps, smart watches and more, was one of the safest ways to care for patients during the pandemic.

Although the use of this type of technology for routine operations such as consultations, control and more is widespread, work is still being done on its implementation for surgery, and this is what is known as telesurgery.

WHAT IS TELESURGERY AND WHAT IS IT FOR?

Telesurgery uses a mechanism of robotic arms and instruments that can be manipulated from a distance, either in adjoining rooms or even from another hospital, city or country. These types of procedures are used when the surgeon does not have access to the patient or to perform less invasive operations.

Although it can be confused with robotic surgery, it differs in the fact that telesurgery is the surgeon who manipulates all the tools. For its part, in robotic surgery the entire operation is performed automatically.

WHAT IS TELESURGERY AND WHAT IS IT FOR?

Even so, for telesurgery the “intelligent operating room” is necessary, which is equipped with a series of robots and interfaces that must be connected and integrated into the operating room in an ergonomic way, taking into account the type of procedure and how many people. that they are going to do it.

One of the advantages that this modality allows is that the instruments used are programmed and this allows greater precision in operations. Any variation in the programming is even detected electronically and notifies the team of the same. This can be compared to the fact of using a GPS to orient yourself, and which ultimately translates into more safety for the patient.

ARTIFICIAL INTELLIGENCE

The first transatlantic surgery took place in 2001 and was carried out by Frenchman Jacques Marescaux, who, while in New York, removed the gallbladder from a patient in Strasbourg. Since then, scientific advances have allowed this type of feat to become more and more common xxx porno.

Marescaux, president of the IRCAD surgery institute and the European Institute of Telesurgery, explained in an interview with Infobae that the use of Artificial Intelligence in surgery aims to reduce complications thanks to the use of surgical and patient data. This allows for more detailed monitoring and avoids risks.

The surgeon also hopes that there will be more support for doctors in the future. For example, he mentions that “machine learning” or automatic learning, health professionals could have early warning not to go ahead with a risky operation.

A ROBOTIC PILL IS THE LATEST BREAKTHROUGH IN HEALTHCARE

Posted on by Martha

A ROBOTIC PILL IS THE LATEST BREAKTHROUGH IN HEALTHCARE

When we think of robotics, we often imagine a dystopian future like in “I Am Legend” or “Ex Machina.” However, this science can contribute a lot to other disciplines such as medicine. One example is the so-called “robotic pill,” one of the latest advances in health.

One of the processes that is often painful and complicated for patients is the issue of injections, especially because fear of needles is so common. Among the alternatives are pills, but these are not the most suitable for all treatments.

That’s where the “robotic pill,” developed by the Massachusetts Institute of Technology (MIT), comes in. MIT’s Traverso lab has been devising different approaches to help patients absorb drugs in the most appropriate way, and this seems to be one of the most feasible.

HOW DOES THE ROBOTIC PILL WORK?

This pill, called RoboCap, is coated with gelatin and, unlike other drugs, it creates a tunnel in the mucosa without using needles. That is, when ingested, this outer layer dissolves and releases a pH, which allows the pill to function in a similar way to a drill.

This happens because the pill has a small motor that, as soon as the pH is released, begins to rotate and thus moves through the tract, creating a kind of tunnel to move the mucosa aside and transport the drug.

As Shriya Srinivasan, a research affiliate at MIT’s Koch Institute for Integrative Cancer Research and lead author of the study published in the journal Science Robotics, explains, using mechanical methods to deliver drugs may allow better absorption.

 

IN WHAT CASES CAN THIS TABLET BE USED?

Traverso’s scientists, who are behind the project, developed the RoboCap using insulin, as well as vancomycin, which is a widely used antibiotic. The reason for using these two drugs is similar. For example, orally administered vancomycin does not reach the skin or infections in orthopedic implants youporn.

IN WHAT CASES CAN THIS TABLET BE USED?

On the other hand, insulin, which is normally received in the form of injections, cannot be taken orally since the intestine and stomach attack it directly as a protective mechanism. Since injections can be very inconvenient for patients, scientists have sought a way to cross the stomach barrier and improve its absorption.

 

ARE THERE ANY ADVERSE EFFECTS?

When we talk about a robotic pill, it is normal to question the possible adverse effects or what happens to the leftovers. According to MIT, after administering the drug, the remains are disposed of by the digestive tract without any problem.

Likewise, in animal tests, no symptoms of irritation or inflammation have been found. Likewise, it has been shown that the perforated area is completely restored within hours of administration.

In addition to allowing better absorption of certain drugs, the procedure also allows 20 to 40 times more drugs to be administered than a similar pill without the tunnel mechanism.

HOW DOES COMPUTER ENGINEERING IMPROVE PUBLIC HEALTH?

In recent years, especially after the impact of the COVID-19 pandemic, public health systems have been at the centre of both political and civil discourse. Of course, one of the major concerns is how to improve them to ensure that patients receive the best possible treatment.

Thus, one of the most interesting conversations is taking place in the area of computer engineering applied to medicine. Also called health informatics, this is the combination of telecommunications, informatics and medicine in order to improve both services and treatments.

This can be achieved through different software as well as different technologies that can support the entire healthcare process. Not only in data storage, but also in diagnostics, patient care and other aspects. In this respect, several steps have already been taken towards its application, especially in Spain.

 

MEDICINE AND INFORMATICS: A WINNING COMBINATION

Multidisciplinarity in any area is often very beneficial. In this case, according to the article “Informatics: impact on the healthcare system” by Víctor Pelegrín Hernando, there are different areas in healthcare that can benefit from the use of informatics.

Among them is the development of telemedicine, which was especially important during the COVID-19 pandemic to avoid transferring patients at a risky time. Another application is in the economic-administrative area, to support the management of resources xnxx, both material and human.

MEDICINE AND INFORMATICS: A WINNING COMBINATION

On the other hand, one of the most revolutionary uses is in medical and healthcare management. In this case, according to the aforementioned article, software can be used for patient administration, allowing health centre staff to carry out admission and other procedures quickly, easily and efficiently.

 

SPAIN SETTING THE STANDARD

In Spain, the public health system has some advantages. For example, the Individual Health Card allows all citizens to use it throughout the national territory, as well as in Europe, and helps with patient identification.

The country also has the Interoperable Digital Health Record of the National Health System or HCDSNS. This project, which has been under development for a decade, allows both patients and health professionals to access the clinical history.

So far, 94% of the Spanish population is part of it. However, this system only allows connections between some Autonomous Communities. On the other hand, according to Jesualdo Tomás Fernández, who is a researcher in Computer Engineering at the UMU, the systems of private and public hospitals are not connected.

SPAIN SETTING THE STANDARD

As we can see, the use of IT in the area of health can have many advantages, such as speed and efficiency. However, for these systems to really work, several factors must be taken into account. Among them, there must be investment on the part of the authorities, staff training and, above all, the citizen must be taken into account.

HOW DOES BIOMEDICINE HELP OUR DAILY LIFE?
BIOMEDICINE

When we talk about biomedicine and bioengineering, it is hard to believe that they are sciences so closely tied to our daily lives. After all, it’s not like we go to the store on a Saturday to buy a robotic prosthetic right leg. However, even if it seems like fiction or a fantasy story, this is getting closer to our reality than we think.

However, before talking about biomedicine or bioengineering in our daily lives, let’s try to understand a little better what it is about. In itself, its name is quite illustrative. It is a discipline that connects engineering with health, to create equipment, machinery and solutions that help us diagnose, treat, cure and prevent diseases.

You see it? It looks a little closer than you imagined, and now we’ll explain why it’s so important tukif.

 

WHY IS BIOMEDICAL ENGINEERING IMPORTANT?

To understand why biomedicine is so important in everyday life, just think about how traditional medicine worked 500 or 1,000 years ago. The flu was a disease that could end your life, a broken arm was more than enough reason for an amputation. And like these cases, examples abound with almost all the emergencies that today we consider, although painful, harmless.

The fact that today we can go to the nearest health center and take an X-ray is an achievement of biomedicine, for example. The same is true of many drugs currently available on the market. Its creation was a joint achievement between chemistry and this discipline.

Biomedicine and medical engineering are therefore a way to improve the general quality of life of human beings. Thanks to their work, doctors are able to provide more timely care and save lives.

Those who dedicate themselves to this professional career are currently highly valued in the professional market due to the positive impact that their work brings to their surroundings. Especially in developed countries, where the proportion of the elderly population is much higher.

 

ARTIFICIAL ORGANS AND LIMBS SAVING LIVES

We already talked about how biomedicine helps the general population. However, one of his greatest contributions is the development of highly sophisticated engineering pieces, which seek to replicate the perfect machine: the human body.

Previously, and going back to amputation a bit, losing an arm meant replacing it with a stick and losing all mobility, if not gangrene killed you first.

Today it is different. Biomedicine has managed to create prostheses that have a design that gives the patient partial or almost total autonomy and mobility, depending on their sophistication. In addition, many of them are designed to replace the lost limb, even aesthetically.

If we get a little more futuristic, it is worth highlighting the great innovations in ophthalmology, with the new ocular prostheses that stimulate the retina and allow an approximation, although rough and rudimentary, to objects and shadows.

What is the most amazing thing about biomedicine for you? Leave your opinion in the comments.

What Types of Different Cybersecurity Exist?

Posted on by Martha

What Types of Different Cybersecurity Exist?

Cybersecurity is the practice of securing computers, electronic systems, servers, networks, mobile devices, infrastructure, and data against malicious threats or attacks. In this age of information technology, people, businesses, and governments use various devices and technology to run their lives or undertakings online. Consequently, there is a demand for people and organizations to keep sensitive information secure. This is where cybersecurity comes in. This article will discuss some types of cyber security that exist today.

 

Application Security

Application security seeks to protect application/program code and data against potential cyber threats. It covers all measures that ensure a secure software development cycle for developers. Its ultimate goal is to enhance security practices by finding, fixing and preventing security issues with applications. As good practice, developers should apply application security through all development phases, including design xxx, development, and software deployment. Cybercriminals often target and exploit vulnerabilities in applications to steal essential data.

 

Network Security

Network security safeguards your network data and infrastructure from breaches, unauthorized access, misuse, modification, destruction and other threats. It entails developing a secure infrastructure for devices, programs, and users to perform their functions within a safe computing environment. Securing a network demands a combination of hardware devices like routers and software such as firewalls, antivirus, and antimalware programs. Government organizations and businesses hire information security analysts to plan and implement security strategies and continuously monitor the effectiveness of the plans.

 

Information/Data Security

Information/Data Security

Information security secures sensitive information from unauthorized activities, including access, inspection, recording, modification, and any cyber threat. Information security encompasses the tools and processes used for protecting data, for example, by setting policies that inhibit unauthorized people from accessing critical data. The aim is to ensure the security and privacy of critical data (like financial data, customer account details, or intellectual property) both in storage and transit.

 

Cloud Security

Cloud security encompasses all the technologies, controls, services, and policies that protect cloud-based systems, infrastructure, applications, and data from cyber threats. Today, most people and organizations prefer to store their data online on Microsoft OneDrive, Google Drive, Apple iCloud, etc. Cloud security is often a shared responsibility between the cloud service provider and clients, who could be individuals and businesses.

 

Internet of Things (IoT) Security

This cybersecurity deals with securing internet devices and the networks that connect them from threats and breaches. The measures protect the devices by identifying and monitoring threats while aiding fix vulnerabilities from an array of devices that can pose risks to the system. The majority of IoT devices lack built-in security, making them vulnerable. Furthermore, they do not have a way of installing security software. Another challenge is that some network security systems often cannot detect these devices or identify which devices are communicating through the network. IoT security integrates solutions that deliver visibility, segmentation, and protection throughout the entire network.

 

Critical Infrastructure Security

Critical infrastructure security aims to protect networks and assets whose uninterrupted operation is necessary to ascertain the safety of a nation, its public health, economy, and general society. It entails all the measures that protect infrastructure like communication networks, energy, financial services servers, IT and data centers, food and agriculture, etc. Such infrastructure is essential, and attacks on them could have widespread consequences. Critical infrastructure cybersecurity is vital to avert the shut down of crucial systems and cyber-terrorists.

 

User Education

User education is essential to avert threats associated with system users. Any person can accidentally introduce a virus to a secure system by not adhering to cybersecurity practices. User education is a security measure that aims to train and educate cyber users about the significance of their actions and inactions. Teaching staff not to open suspicious email attachments and not to plug in unknown USB drives alongside other essential lessons is crucial for the security of any computer system.

5G Technology: Advantages and Disadvantages

Posted on by Martha

As communication technologies continue to advance, the world has experienced the emergence of several generations of data technology. From 2G, 3G, 4G, 4G LTE, and now 5G is in its early stages of rollout. While the 5G is not yet the mainstream network, it is the future of communication. Here are some pros and cons that you can expect with 5G networks.

 

Advantages of 5G Technology

The advantages of 5G technology include;

 

High Speeds

5G will deliver speeds a hundred times faster than 4G LTE. With speeds of more than 10Gbps, downloads will occur in seconds, not minutes. This will mean exciting possibilities for users like faster downloads and streaming of high-resolution videos.

 

Enhanced Mobile broadband

5G provides faster data speeds and greater capacity to connect the world. The technology will support fixed wireless home internet access, improve connectivity for those on the move and outdoor broadcast applications (no need for broadcast vans), and the internet of things (IoT).

Increased Capacity

5G delivers high speed for a massive number of users and connected devices all connected simultaneously. The technology allows users to switch between Wi-Fi and wireless strategies for enhanced performance xxx. This will facilitate seamless connectivity despite spikes in network usage.

 

Increased Bandwidth

5G technology will allow for the transmission of large amounts of data than is possible with 4G LTE technology. This translates to less network congestion, which means users will seamlessly download files, watch videos, and view internet pages at faster speeds.

 

  • Low Latency

Latency measures the duration for a signal to travel from the source to the destination and back. 5G networks have lower latency compared to 4G networks. Minimal lags will make it possible to control remote devices in almost real-time and provide a seamless experience for virtual gaming, virtual reality, and augmented reality application and business.

 

Disadvantages of 5G Technology

The possible downsides to 5G technology include;

 

Cybersecurity

5G cybersecurity requires some significant enhancements to shun the risks of hacking. Some security concerns emanate from within the network, while others involve the gadgets linking to the network. The two may expose consumers, enterprises, organizations, and governments to cybersecurity risks.

 

Limited coverage and availability

The example of General Stress Optics

Posted on by admin

High-precision 3D contouring of gears for aerospace industry General Stress Optics has developed the necessary technology to perform high precision contouring. A study was carried out in which the profile of a spur gear was measured using our technology; the results were compared to results obtained via CMM. Below we see the 3-D reconstruction of one gear tooth obtained by us. The results below show that the agreement in between the two procedures is within 1-micron.

Complex geometries or high tolerance requirements push mechanical measuring devices to their limits, with the aid of optical techniques one can obtain fast and highly accurate results. One example is the spiral bevel gear which has a very complex geometry and is difficult to measure using CMM. For that reason most of the time the qualification of a gear is determined via a 9×5 matrix test in which the points are taken along the described matrix. These points are then matched to the master that is also measured and the values are compared. If one wishes to obtain a more detailed analysis it would require increasing the matrix size and thus increase measurement time.

With our technology one can obtain a full field view of the surface and therefore is not limited to a small matrix of points. In this case in order to demonstrate the power of the technique we simplified our measurement to the same matrix and below one can see how well they agree to the points measured via CMM.

Holographic Moiré to new heights. We were able to measure displacements in the nano-meter range.The Bi-Metal Laminate composite that was measured for this experiment had a thickness of 0.008″(~200 microns). The set up that was used can be seen in the images below. An optical bench was attached to an Instron machine, a special fixture was designed to illuminate the surface while the piece experienced the compression. The field of view was 480 x 360 microns and we had resolution in the micron range. With the power of the HMSA we were able to obtain strain values and create graphs that contain the loading and unloading properties of the Bi-Metal Laminate Composite along with a 3-D representation of the strain field at specific loads.

By using the Holo-Moiré Strain Analyzer, dynamic analysis of stresses and strains of the turbine blades was possible. The resonant frequencies of the turbine (up to 55,000 Hz) were determined. The stresses and strains to the critical areas of the blades were also measured. The images provided show several stages of resonant modes.
