肝血管瘤是一种有纤维包膜、呈膨胀性生长的肝脏良性肿瘤。作者介绍应用自己设计的负压吸引式切肝锯刀沿肝血管瘤包膜切割分离，切碎的肝组织和创面渗血可随时被负压吸引管道吸走，使术野显露清楚。分离出进出血管瘤的大的管道结构后钳夹、切断、结扎肝创面血管断端。这种手术方法操作简便，出血少，可多保留正常肝组织，减少手术并发症。 Hepatic hemangioma is a hepatic benign tumor with a fibrous capsule and expansive growth. The authors introduced the use of their own design of negative pressure suction type liver cutting saw along the hepatic vascular tumor capsule separation, chopped liver tissue and wound bleeding can be suctioned at any time by vacuum suction pipe, so that the surgical field revealed clearly. After separating the large-scale tube structure into and out of the hemangiomas, the hepatic wound vessel ends are clamped, severed, and ligated. This surgical method is simple, less bleeding, can retain more normal liver tissue and reduce surgical complications.
