Background

The ultrasonic cutting blood coagulation knife utilizes ultrasonic energy to cut and coagulate and stop bleeding of soft tissues, and is widely applied to surgical operations due to the advantages of fast cutting, good coagulation, small side tissue damage, clear visual field in the operation, simple and convenient operation and the like. Surgical smoke refers to smoke-like substances which are visible in surgical operation and are also called as collosol, scorching smoke and the like, and energy is transmitted to cell tissues by using electric surgical equipment such as a laser knife, an ultrasonic knife, a high-frequency electric knife, a high-speed drill, a saw blade and the like, and the generated heat raises the pressure in cells, so that adjacent cells are finally necrotized. The untimely smoke absorption of the operation can cause the mirror surface atomization of the laparoscope, the visual field definition is poor, the smooth operation is obstructed, and the carbon-oxygen hemoglobin content can be increased due to the absorption of the smoke by the tissues of a patient, thereby causing headache and vomiting in the operation. If the smoke is directly discharged into the air, the air pollution of the operating room is easily caused, and the health of the operating personnel is also damaged. Compared with an electrotome, the ultrasonic scalpel is relatively safe and generates less harmful smoke. Under the condition that the conditions permit, the ultrasonic scalpel should be selected as far as possible in the operation, and particularly has the characteristics of less coke smoke and high performance, but needs to be used according to the operation instructions of equipment. It has been reported that the ultrasonic blade is seriously damaged to the cutter head when the ultrasonic blade is continuously operated for 10s, and the generation of aerial fog is the most, so that the ultrasonic blade needs to be restarted when the ultrasonic blade is used for 7 s. The surgeon needs to cut accurately, shorten the use time, avoid the carbonization of cut tissues and clean the eschar of the ultrasonic scalpel in time so as to reduce the generation of surgical smoke.
