35N Semi Shaft Extended Linear Voice Coil Motor For Precision Medical Devices

The SUPT model VCAB0035-0105-00A is a medical-grade semi-shaft-extended linear voice coil motor developed for precision medical devices. It features a peak thrust of 35N, a continuous thrust of 15.6N, a total stroke of 10.5mm, and a stator diameter of 50mm. a moving coil weight of 91 g. It features a built-in medical-grade precision linear bearing and a wear-resistant drive shaft, with an M3 internal threaded shaft end design that allows direct connection to medical device actuators. It perfectly meets the high-precision, high-reliability drive requirements for applications such as minimally invasive surgical instruments, in vitro diagnostic instruments, medical imaging equipment, and implantable medical devices.

 The motion shaft of this linear voice coil motor is made of high-quality, lightweight, high-stiffness, and wear-resistant materials. It features a lightweight armature coil, short response time, high frequency, and high positioning and repeatability accuracy. It enables precise manipulation of minimally invasive surgical instruments, precise positioning of diagnostic instruments, and rapid focusing of imaging equipment. It operates smoothly without stuttering, mechanical hysteresis, or backlash, ensuring the accuracy and safety of medical procedures.

 Additionally, the linear voice coil motor features a design with low electromagnetic radiation and resistance to electromagnetic interference. It does not interfere with the normal operation of precision electronic medical equipment such as electrocardiographs, monitors, and imaging systems. It is adapted to the complex electromagnetic interference scenarios found in medical environments and can withstand alcohol wiping, ethylene oxide sterilization, and high-temperature, high-pressure disinfection. It exhibits no performance degradation over long-term use, ensuring a long service life.

The voice coil motor can be directly integrated into the confined spaces of medical devices, and its M3 internal thread at the shaft end allows for quick connection to actuators such as surgical instruments, diagnostic probes, and focusing lenses without the need for additional machining, significantly simplifying the design and assembly processes of medical devices. Compared to traditional actuators, the VCAB0035-0105-00A eliminates intermediate transmission components such as gears and lead screws, resulting in a more compact structure, higher reliability, and better biocompatibility. It provides a safe, precise, and highly reliable direct-drive solution for the precision medical device sector.
