Abstract: Objective Comparative analysis of the application effects of straight bipolar coagulation forceps,Focus ultrasonic equipment and high frequency electrosurgical equipment in thyroid cancer surgery. Methods Select 165 patients accept standard radical resection of thyroid cancer from May 2020 to April 2021.Divide randomly into bipolar electrocoagulation group,ultrasonic equipment group and electrosurgical equipment group,with 55 cases in each group.The general patient’s information of the three groups are operation time,intraoperative blood loss,postoperative drainage time,total drainage,preoperative and postoperative parathyroid hormone value,serum calcium ion value,postoperative complication rate and individual costs.This study conducts a comparative analysis of these indicators. Results The three groups of operations were successfully completed;the bipolar electrocoagulation group and the ultrasonic equipment group have significant differences in the postoperative parathyroid hormone value,serum calcium ion value,and postoperative complication rate,and they were statistically significant(P< 0.05),the rest of the indicators were not statistically significant(P>0.05).Among them,the single cost of the bipolar electrocoagulation group is higher than that of the ultrasonic equipment group.The first two groups are compared with the electrosurgical equipment group and find that the operation time,intraoperative blood loss,and postoperative Drainage time,total drainage volume,postoperative parathyroid hormone value,serum calcium ion value,and complication rate are all lower than those in the electrosurgical group,the difference was statistically significant(P<0.05),and the individual cost is higher than that in the electrosurgical group. Conclusion All three groups of energy devices can successfully complete the operation and achieve the treatment goals.In the operation time,intraoperative blood loss,postoperative drainage time,total drainage,postoperative parathyroid hormone value,serum calcium ion value and complications In terms of efficiency,straight bipolar coagulation forceps and Focus ultrasonic scalpel have advantages in higher frequency electrosurgical units.In terms of economy,straight bipolar coagulation forceps are slightly higher than high frequency electrosurgicals,but they have obvious advantages over Focus ultrasonic scalpels.Straight bipolar coagulation forceps has an absolute advantage in fine anatomy.
