It’s always best to use components designed for specific industries or applications. This line of motors was designed for surgical powered hand tools—arthroscopic shavers, ENT microdebriders and large bone drills. Plus, they withstand up to 1,000 cycles of autoclaving.
Arthroscopic shaver brushless dc mini motors drive powered surgical hand tools used in minimally invasive joint surgery; surgical procedures that are responsible for repairing joints such as hip, knee, and shoulder joints. No-load speed of the arthroscopic shaver motors ranges from 4,000 to 7,000 rpm, while maximum continuous torque is 117 to 119 mNm.
Large, bone-drill brushless dc mini motors consist of a cannulated gearbox and motor to allow for in-line pin and k-wire driving and provide high torque at operating speed. These battery-powered systems meet extreme torque demands without stall during joint replacement surgeries such as those of the knee, hip, and shoulder. The large bone-drill motor offers a no-load speed of 950 rpm with maximum continuous torque of 818 mNm.
Ear, nose, and throat (ENT) brushless dc mini motors have the high speed and high torque required by powered surgical hand tools used in minimally invasive surgical procedures of the ear, nose and throat as well as arthroscopic surgeries of small joints. With no-load speeds of 11,800 rpm and a maximum continuous torque of 39 mNm, these motors perform precise cutting of tissue and clean burring of bone. For high-speed drilling in spine, cranial, maxiofacial, and otologic (ear) surgery, a spine drill will provide 90,500 rpm of no-load speed and 9.2 mNm maximum continuous torque.
