Abstract

The invention discloses a cutting control method and device applied to an ultrasonic knife and a storage medium. Detecting the current active power of the ultrasonic knife; and under the condition that the current active power is greater than a preset power critical value and the duration of the current active power greater than the power critical value reaches a first preset time, gradually reducing the rated working current of the ultrasonic knife in a stepped manner according to a preset time interval. According to the method, whether the ultrasonic knife enters the cutting tail section or not is accurately recognized by detecting the active power of the ultrasonic knife, so that when the ultrasonic knife enters the cutting tail section, that is, when the cut tissue is slightly changed, the working current of the ultrasonic knife can be adjusted in time, the energy output of the ultrasonic knife is reduced, and thermal damage to the tissue can be effectively prevented.

Description

technical field [0001] The present application relates to the technical field of ultrasonic knife, in particular to a cutting control method, device and storage medium applied to ultrasonic knife. Background technique [0002] Ultrasonic cutting hemostatic knife, referred to as ultrasonic knife, is a new medical device that has been used in surgical operations abroad since the late 1980s. It is generally used in thoracoabdominal surgery, because it can complete cutting and hemostasis at the same time, it is deeply loved by doctors and has become an important tool in surgery. [0003] The ultrasonic scalpel generates heat through high-frequency vibration during the working process, and the heat energy generated by this friction can coagulate and stop bleeding while cutting tissue. However, due to the limitation of the control algorithm and hardware, the existing front ultrasonic knife is generally controlled by AD sampling and averaging method, so the energy output cannot be...
