TriboSys™ Biocompatible Medical Device Lubricants

Searching for a Biocompatible Medical Device Lubricant?

Medical device lubricants for minimally invasive medical robots have an increasing demand in the healthcare system. Medical device manufacturers often overlook the importance of selecting the most optimal high-performance biocompatible lubricant for their application. The increased implementation of these robotic devices will challenge the device’s longevity and long-term wear prevention will become paramount. With this demand comes a critical need for the robots to be very durable, reliable and extremely accurate to execute the task being directed. Robotic developments in the medical field have led to better diagnostic practices, shorter hospital wait times, tailored surgical procedures, reduced infection rates, less invasive and safer surgery. TriboSys™ medical device lubricants have a proven track record to deliver the highest quality performance and protection to critical pivot points and robotic components over traditional hydrocarbon lubricants. TriboSys™ lubricants utilize proprietary PFPE (Perfluoropolyether) base oils that exhibit exceptional thin-film lubrication, thermal stability, and migration resistance. The nonflammable, chemically inert, biocompatible (ISO 10993 certified), non-hazardous and non-nutrient properties of the TriboSys™ lubricants eliminate any risk of flashpoints or catastrophic failure during operation. Miller-Stephenson’s TriboSys™ medical device lubricants not only offer increased safety and reliability, they also provide superior mechanical longevity. Selecting and utilizing a TriboSys™ biocompatible fluorinated lubricant over conventional hydrocarbon or silicone lubricants will elongate the robots service life, greatly reducing scheduled service intervals and unexpected mechanical wear-based failures.

What is the advantage of TriboSys™ Biocompatibility?

With the constant need to reduce patient’s blood loss, skin scarring, hospital stay time and exposure to hospital acquired infections, there is a growing need for surgical robots to perform and articulate more frequently and in smaller, tighter and increasing challenging areas of the human body. Surgical robots currently using hydrocarbon-based lubricants are facing higher stress loads, temperatures and usages which can result in faster component wear and eventual component failure. Miller-Stephenson’s TriboSys™ lubrication line utilizes PFPE base oils that are referred to as “liquid Teflon™”. These low-friction polymers yield extended component life through substantial reductions in wear and friction-related failures and are compatible with all elastomers, plastics, metal and metal alloys. With useful operating temperatures that span from -75°C to 350°C, selecting and utilizing TriboSys™ fluorinated lubricants over conventional hydrocarbon lubricants will elongate the robots service life, greatly reduce scheduled service intervals and reduce the risk of premature mechanical failures. On a molecular level, the PFPE oil polymer is composed entirely of oxygen, carbon and fluorine which heavily shields the molecule from oxidation due to high temperature, high pressure and mechanical forces, therefore making PFPE oil a much stronger, durable polymer chain vs. an equivalent hydrocarbon or silicone polymer. Our TriboSys™ greases utilize PFPE base oil and are fortified and thickened with PTFE (Polytetrafluoroethylene) to form a white creamy grease that is biocompatible, nonflammable, oxygen safe, odorless, non-staining and chemically inert. TriboSys™ PFPE lubricants are unaffected by all forms of sterilization techniques and will not transfer or degrade under these conditions.

What are the negatives of Hydrocarbon Lubrication?

Hydrocarbon lubricants are the most widely used medical lubricants and while their price and relative performance are suitable for many applications, there are critical disadvantages that should be mentioned.

Hydrocarbon lubricants tend to transfer, fail and break down under extreme temperature, pressure and chemical exposure, causing downtime and the need for frequent relubrication. These lubricants break down to form carbonaceous, gummy residues leading to accelerated wear, poor lubrication, and premature component failure. Moreover, this class of lubricants are susceptible to bacterial and fungal degradation and can even facilitate growth of these organisms.  For medical device manufacturers looking to ensure optimal component life, minimize long-term wear, and produce the highest quality device possible, TriboSys™ PFPE-based lubricants is your optimal path forward.

Why choose TriboSys™ PFPE Biocompatible Lubricants?
