为提高肝切除的安全性 ,减少术中及术后出血及胆漏等并发症的发生。我们根据肝实质与管道系统质地的显著差异 ,利用钝性切割分离和强力吸引原理自制吸引刀 ,先行大动物活体实验 ,再应用于临床肝切除术。现将结果报告如下 :1　刀具的制作及操作方法1 1　刀具的制作取长 30 0ｍ In order to improve the safety of hepatectomy and reduce complications such as intraoperative and postoperative bleeding and bile leakage. According to the significant difference between the liver parenchyma and the plumbing system texture, we made use of the blunt cutting separation and the principle of strong attraction to make self-made suction knives. The first large-scale animal experiments were performed and then applied to clinical liver resection. The results are reported as follows: 1 tool production and operation methods 1 1 take the tool to take a long 30 0m
