DC motor selection is argued to be one of the most important steps in providing motion control of a medical machine - whether for prosthetics, medical tools, robotics, or medical training aids. In order to properly use the many types of motors available on the market, users must have a complete understanding of the application parameters, including power, speed, torque, physical size, efficiency, and lifetime expectations. This article points out the basic differences between DC brushed and brushless motors, what they can do, where they fit best, and how to make a selection for each application.
Many engineers encounter the challenge of implementing fast, accurate, and powerful linear actuation within a small, allocated volume. This article presents the advantages and disadvantages of rotary DC motor driven actuators and linear DC motor actuators, and considerations for choosing one or the other.
Motors in artificial limbs can serve a range of functions. This article focuses on overcoming the challenges of axis coordination in a multi-axis system through the use of balancing modularization and integration.
As the medical device industry grows, more emphasis is being placed on the use of bioabsorbable implants. Traditional sterilization methods that are used on bioabsorbable materials pose significant problems, so other methods are valued that will impose much less risk of damage. This white paper reports on how the innovative usage of vaporized peracetic acid (VPA) offers a safe, reliable, and versatile method for sterilizing bioabsorbable implants.
There are a wide variety of materials to choose from when it comes to micro medical components. In this article, MTD Micro Molding answers some of the most commonly asked questions about bioabsorbables.
If you are planning a plastic injection molding project, and want to ensure excellence and product delivery - review these five considerations to make certain the result is exactly what you need.
The two types of sensing include local measurement points and distributed sensing. This paper presents the technical basics behind sensing over fiber technologies, its main applications, and the cabling solutions involved.
As an OEM, it is your responsibility to ensure the parts supplied to you are compliant with ISO regulations. That is no easy task. Ideally, your supplier’s quality systems are strong enough to identify risks, prevent defects, and to catch defects quickly if they do occur. This requires a robust quality management system. When it comes to evaluating the quality systems of your medical device supplier, where do you begin?
As technologies in one area advance, they will combine with other technologies to enable entirely new capabilities. The medical device industry will need to take a broader view of R&D to remain innovative.
