背景技术Background technique
随着医学技术的发展,运用腹腔镜技术的微创外科手术在国内也日益得到推广使用。在腹腔镜手术中多采用2-4孔操作法,其中一个开在人体的肚脐眼或者腹部的其他部位上,避免在病人腹腔部位留下长条状的伤疤,恢复后,仅在腹腔部位留有1-3个0.5-1厘米的线状疤痕,可以说是创面小,痛楚小的手术,因此也有人称之为“钥匙孔”手术。腹腔镜手术的开展,减轻了病人开刀的痛楚,同时使病人的恢复期缩短,并且相对降低了患者的支出费用,是近年来发展迅速的一个手术项目。With the development of medical technology, minimally invasive surgery using laparoscopic technology has been increasingly popularized and used in China. In laparoscopic surgery, 2-4 holes are often used, one of which is opened on the navel of the human body or other parts of the abdomen, so as to avoid leaving long strips of scars on the patient's abdominal cavity. There are 1-3 linear scars of 0.5-1 cm, which can be said to be a minimally invasive and painful operation, so some people call it "keyhole" surgery. The development of laparoscopic surgery reduces the pain of surgery for patients, shortens the recovery period of patients, and relatively reduces the expenditure of patients.
