Description

technical field [0001] The invention belongs to medical instruments, in particular to a device for flushing and drying the laparoscope in laparoscopic surgery. Background technique [0002] As an important part of minimally invasive surgery, laparoscopic surgery has become one of the development directions of surgery in the 21st century due to its advantages of less trauma, less postoperative pain, less cross-infection between doctors and patients, and remarkable curative effect. During laparoscopic surgery, due to the temperature difference between the inside and outside of the abdominal cavity or the temperature difference on both sides of the objective lens when cutting tissue, fog will be formed on the objective lens of the laparoscope; in addition, blood stains will be splashed on the objective lens when tissue is cut or blood vessels are accidentally damaged superior. Therefore, fog and blood stains often appear on the objective lens during laparoscopic surgery, affec...
