A new insufflation device for laparoscopic surgery has been developed which permits the persufflation of the abdominal cavity with humidified CO2 at 37 degrees C, with flow rates of 4 l/min/mm of mercury (3 l/min/cm of water) insufflation pressure, i.e. 60 l/min for an insufflation pressure of 15 mm of mercury (20 cm of water). The device consists essentially of an operative laparoscope with a large side opening of 7 mm internal diameter, and a pressure valve limiting the insufflation pressure. The device is safe, since the intraabdominal pressure can never exceed the insufflation pressure. The device has been extensively tested in greater than 500 CO2-laser-endoscopic procedures and has proven to be safe and useful. Smoke can be constantly removed and the pneumoperitoneum is unaffected even by the removal or leakage of large volumes of CO2 from the pneumoperitoneum.
一种用于腹腔镜手术的新型充气装置已被研发出来，它能够以37摄氏度的温度向腹腔持续注入加湿的二氧化碳，注入压力为4升/分钟/毫米汞柱（3升/分钟/厘米水柱），即当注入压力为15毫米汞柱（20厘米水柱）时，注入流量为60升/分钟。该装置主要由一台内径为7毫米的大侧孔手术腹腔镜和一个限制注入压力的压力阀组成。该装置是安全的，因为腹腔内压力绝不会超过注入压力。该装置已在超过500例二氧化碳激光内镜手术中进行了广泛测试，并且已被证明是安全且有用的。烟雾能够持续被清除，即使大量二氧化碳从气腹移除或泄漏，气腹也不会受到影响。
