Title: Longyang Yao and Temperature-Controlled Ultrasonic Scalpel Technology.

Introduction

Longyang Yao is an inventor based in Suzhou, China, and works at Innolcon Medical Technology (Suzhou) Co., Ltd. His patent work focuses on medical technology, including methods for estimating and controlling the temperature of an ultrasonic scalpel blade shaft.

Latest Patents

Yao is associated with 1 patent: “Ultrasonic Scalpel Rod Temperature Control Method and System Based on Temperature Distribution Function Model.” The invention estimates the blade shaft’s real-time temperature distribution using operating feedback, physical characteristics, and environmental parameters. A machine-learning model approximates the temperature distribution function using inputs such as resonance frequency, voltage, current, impedance, power, blade-shaft shape, and environmental conditions. The system then uses the estimated temperature to control power, aiming to provide accurate and effective temperature regulation.

Career Highlights

Yao’s patent reflects an application of machine learning to temperature management in ultrasonic surgical instruments. By estimating temperature along the blade shaft rather than relying on a single measurement, the disclosed approach connects device operating data with power control.

Collaborations

The patent lists Zhenzhong Liu and Fuyuan Wang as Yao’s coworkers. The invention describes a system in which the ultrasonic scalpel blade shaft and transducer are coupled and connected to a generator by cable.

Conclusion

Longyang Yao’s patent work at Innolcon Medical Technology highlights an approach to ultrasonic scalpel safety and performance through model-based temperature estimation and power control.
