Best Linear Actuators Used In Medical Equipment

An actuator is a useful piece of technology that has already brought innovation to a lot of areas of human lives, and, with further improvement, is going to do even more. One of the most important areas for such a modernization is medicine. The recent technological advancements have made it a good idea to include linear actuators in medical devices, both in the applied field of this science and in medical research. However, the development of the technology has led to large quantities of different types of actuators being available out there. Which one would suit your venture the best? Let’s find out.

How Do Linear Actuators Work?

In order to determine which linear actuator would suit your needs the best, you need to know how different types work. The linear actuator is a motor that provokes a motion of something along a straight line. Most of them convert the circular motions of a motor into the linear motion we need.
Linear actuators that work on electricity are based on the same principle, too. With the help of a screw, it transforms a circular motion of the electric rotor into the motion of the rod. Recent technologies have made it possible to make this motion much more accurate and less power-consuming, which has led to the decrease of the actuator’s size. Since then, there has been a surge of new ways of using linear actuators in medical equipment. Let’s have a look at the most popular uses out there.

How Are Linear Actuators Used In Medical Equipment?

1. Patient rooms

Probably the first piece of medical equipment the actuators have been used for is a patient’s bed with an adjustable back angle. Nowadays, linear actuators can be used to help handicapped patients reach for something or adjust their position. They can also be used for more important medical “furniture”, like operating tables. This is perhaps the simplest way of using this technology, although it still requires a lot of skill and knowledge to implement.

2. Prosthetic limbs

Simulating a natural movement of our limbs would be impossible without linear actuators. However, scientists and engineers have only recently come close to it, with the help of the smallest and most accurate actuators. Such devices require a high level of precision in their work, which makes it very difficult to find a suitable actuator for them.

3. Medical robots

Although it seems like something out of a science-fiction tale, medical robots have been used for different purposes for decades. The first surgical robot helper was used in 1985, and since then the technology has continued to improve. Now there are talks of minimizing the presence of a surgeon in the room with the patient. Of course, there is a long way to go before we reach such a future, but linear actuators can be considered a major factor in making it at least possible.
Creating and operating a medical robot is also not a trivial task. In order to choose a linear actuator for a small functioning part of it, you would need years of specific education.

4. Medical research

There are a lot of different ways a linear actuator can be applied in medical research. Mostly, though, it is used during the chemical and biochemical research, either to stabilize the position of compounds or for a good shake to make the reaction possible. If there are a lot of samples and reagents, an actuator-based system can be used to provide an easy and quick access to them. There also are some invasive procedures that could use some help from the actuator implementation.

How To Select The Most Suitable Linear Actuator For Your Project?

First things first, the best linear actuators for the medical industry are the electric ones. They are easy to control, have an almost infinite life expectancy, and are much more accurate than any other type of actuators.
It is difficult to say which actuator model is the best because most of them are suitable for specific tasks. The way for you to choose which one of them is the best for your purpose is to measure the parameters of your system and match them with the parameters of the actuators available.
It sounds pretty easy to do, but in reality is much harder. It is rather difficult to calculate the force you’d need for such a complex system, and the stroke of the actuator doesn’t really reflect its resolution, which might be quite different on the maximum and minimum strokes. However, you can always ask someone for help.

Why Choose ProgressiveAutomations?

ProgressiveAutomations is one of the companies that you can contact not only to buy almost any type of the device you need, but also to ask any questions you might have about each and every one of them. The company is not only the distributor, but also the developer and maker of the actuators, so there are plenty of people who know what they are doing.
Furthermore, you can apply to get a custom product designed exclusively for your system and your needs. Not only can you develop your own actuator almost from scratch, but you can alter the engine that almost suits you and modify it in any way you need. They also offer a lot of additional products that make the implementation of the technology much easier and more fun.

Conclusion

All in all, it’s impossible to determine which linear actuator for medical equipment is the best. However, you can still find out which drive suits your project the best. Although this task is quite difficult, you can easily find experts that will help you to determine the parameters of your system and make a thought-out decision.
