ABSTRACT
Objective To evaluate the application of a new laparoscopic hepatic forceps for laparoscopic liver resection in pigs.Methods A laparoscopic hepatic forceps was designed by using the CAD software,and was manufactured in coordination with the Hangzhou Kangyou Medical Company for pilot tests.An assessment was made on outcomes of the forceps for blocking hepatic blood flow and controlling cut surface hemorrhage in laparoscopic hepatectomy in 12 pigs.Results The experimental group had a significantly lower intraoperative blood loss than control group(47.8 ?6.9 ml vs 86.3?3.9 ml;t=11.898,P=0.000) and a significantly shorter operation time than control(53.2?7.4 vs 97.5?5.8 min;t=11.541,P=0.000).No significant difference was observed in the weight of resected liver between experimental and control groups(34.7?4.2 g vs 35.3?4.2 g;t=0.245,P=0.812).Conclusions This new laparoscopic hepatic forceps can be used for the occlusion of liver blood flow,offering advantages of less blood loss and shorter operation time and facilitating laparoscopic performance in liver resection.
