Abstract: The present invention discloses a temperature control method and a system for a blade shaft of an ultrasonic scalpel based on a temperature distribution function model. The system includes the blade shaft of the ultrasonic scalpel and a transducer that are coupled to each other, and is connected to a generator through a cable. When the blade shaft of the ultrasonic scalpel works, actual temperature of the blade shaft is distributed along a one-dimensional space of the blade shaft. The temperature distribution on the blade shaft is determined by a set of the real-time working feedback parameter, the physical structure feature parameter, and the surrounding environmental parameter of the blade shaft. Each temperature distribution corresponds to a solution of the temperature distribution function, and the function can be approximated by a machine leaning algorithm.

Abstract: An ultrasonic phacoemulsification handpiece with a sensor and a surge control system and a method. The central aspiration lumen of the ultrasonic phacoemulsification handpiece consists of two components of plug-in loose fit: a fixed lumen and an extension lumen; a small pressure sensor is mounted on the extension lumen, but still able to keep the easy-to-use size and maintain the ultrasonic performance of the handpiece. The extension lumen minimizes the effect of ultrasonic vibration on the sensor while maintaining sufficient stiffness for installing and removing the phacoemulsification tip. The design of the handpiece transducer reduces the effect of this sensor installation on the ultrasonic performance. For ultrasonic phacoemulsification cataract removal surgery, the short distance from the pressure sensor to the surgical site provides a technical solution for reliably controlling the risk of the post occlusion surge.
