ConMed Linvatec, a leading global supplier of arthroscopic devices, multi-specialty endoscopic medical video systems, and powered surgical instruments, has developed the industry’s first UL-approved autoclavable battery. The Hall? Lithium Battery system, which powers surgical tools for reconstructive orthopedic procedures, features a battery housing made of AvaSpire? polyaryletherketone (PAEK) resin from Solvay Specialty Polymers.The recently introduced L3000LG version of the Hall? Lithium Battery System represents the latest in battery technology for powered medical instruments. Its Lithium-powered performance provides nearly twice the power of standard batteries1 for uninterrupted use during demanding procedures. The novel battery system also provides significantly longer battery life and product life than standard batteries1, resulting in greater cost savings. It is 25% lighter than standard batteries1 and designed with environmentally acceptable materials for recyclability.
The battery has the ability to be immediately autoclaved with other instruments in a single tray, unlike standard batteries1. AvaSpire? PAEK is used to injection mold the black rectangular enclosures which measure 3.5-in (8.9 cm) high, 3.25-in (8.25 cm) long, and 2.5-in (6.35 cm) wide. AvaSpire? PAEK is capable of withstanding an autoclave temperature of 134°C (275°F) and is chemically compatible with aggressive hospital disinfectants and cleansers. The high-performance 30% glass-filled grade of AvaSpire? PAEK provides high strength, ductility, and impact resistance, along with a UL 94 V0 flammability rating at 0.8 mm.
“While AvaSpire? PAEK provides high performance in this innovative new battery system, it is the product’s unique combination of properties that sets it apart from competitive materials,” said Mike DeCesare, R&D engineer for ConMed Linvatec.
The three-piece battery pack consists of a lever and two enclosures made of AvaSpire? PAEK which are welded together. ConMed Linvatec expects to use AvaSpire? PAEK in similar lithium battery designs including the L3000SM model which is scheduled to be launched next year.
AvaSpire? is a versatile family of polyaryletherketone (PAEK) resins that are tailored to provide new and unique combinations of performance and value. The AV-600 Series delivers a range of distinctive performance attributes with some grades offering more attractive economics when compared to PEEK. The AV-700 Series offers comparable performance to PEEK at up to a 30% lower cost.
