摘要

Ultrasound knife, also known as ultrasonic cutting hemostatic knife, is a new type of surgical equipment that began to be applied in clinical surgery in the late 1980s. Ultrasound scalpels are currently widely used in China. However, most of the ultrasound scalpels used in hospital clinical practice are imported from abroad, and there are fewer ultrasound scalpels developed and produced domestically. The reason is that the research and development technology of ultrasound scalpels abroad is closed, and the verification and evaluation of the lifespan of ultrasound scalpels is difficult. This article will conduct research on the application of accelerated life testing for a certain type of ultrasonic knife system in China, propose a comprehensive verification method for the reliable life of the ultrasonic knife system, select appropriate acceleration stress and application method, calculate the acceleration factor through the corresponding acceleration model, design an accelerated life testing plan for a certain type of ultrasonic knife system, and finally verify the reliable life through conducting experiments.
