Case Study: Facilitating Multi-Output Power Supplies for Surgical Robotics

Pioneering the Advancement of Medical Robotics

Astrodyne TDI equips a prominent medical technology company with its advanced handheld robotics platform, transforming surgical procedures in today's compact operating rooms. This groundbreaking solution effortlessly combines 3-D intraoperative imaging with sophisticated robotic precision tools to improve surgical accuracy and patient outcomes. By employing cutting-edge camera technology, the platform greatly reduces cutting time in knee arthroplasty procedures, resulting in better patient-reported outcomes and faster recovery times. The advantages of robotic-assisted surgery are indisputable, providing patients with a quicker return to an active lifestyle and reduced hospital stays.

Multi-Output Power Supply for Handheld Medical Robotics System

The medical technology company required a customized power assembly that included a broad input AC range from 90VAC to 264VAC, functioning at 48Hz to 62Hz, with Class I Earth Ground specifications. They needed output voltages consisting of a primary power supply (Power Supply #1) delivering 48VDC at 550-600W, and a secondary power supply (Power Supply #2) providing 12VDC at 300-400W, along with 5Vsb. Additionally, they emphasized the need for GPIO support for AC OK, DC OK, and Remote On/Off features, as well as adherence to safety standards such as IEC60601-1, 2MOPP, BF, and IEC60601-1-2 Class B.

Astrodyne TDI Power Distribution Solution for Medical Robotics

Astrodyne TDI developed a custom multi-output assembly that includes two of their advanced standard power supplies and a specially designed PCBA for efficient communication and monitoring through PMBus in a cart-based medical environment. Power Supply #1 utilized the Astrodyne TDI ASM550-480-BNH-S00 model, while Power Supply #2 incorporated the reliable Astrodyne TDI ASM400S-12 standard. The expertly crafted PCBA by Astrodyne TDI enabled the monitoring and management of AC OK, DC OK, and Remote On/Off for both PSU1 and PSU2, with connections made via a Molex-type connector. This PCBA also functioned as the output interconnect for PSU1 and PSU2, allowing connections through terminal blocks for optimal performance.
