笔者团队开展单孔腹腔镜手术10余年，至今已累计完成各类单孔腹腔镜手术1 000余例，包括单孔腹腔镜胆囊切除、单孔腹腔镜脾部分切除、单孔腹腔镜半肝切除等，积累了丰富的单孔腹腔镜手术经验和操作技巧。团队自主研发了一种不占腹腔镜通道的T型记忆金属线用于经脐单孔腹腔镜胆囊切除术中的辅助牵拉暴露，该方法与传统单孔腹腔镜胆囊切除相比增加了一个1.8 mm的辅助牵拉孔，其术后美容效果与常规单孔腹腔镜胆囊切除术一致，但大大减少了手术时间和操作难度。本视频展示由笔者团队自主研发的T型记忆金属线辅助牵拉暴露的经脐单孔腹腔镜胆囊切除术的操作过程。

The author's team has carried out single-hole laparoscopic surgery for more than 10 years, and has completed a total of more than 1000 cases of various types of single-hole laparoscopic surgery, including single-hole laparoscopic cholecystectomy, single-hole laparoscopic partial splenectomy, single-hole laparoscopic semi-hepatectomy, etc., accumulating rich experience and operational skills in single-hole laparoscopic surgery. The team independently developed a T-shaped memory wire that does not occupy the laparoscopic channel for the auxiliary stretch exposure in transumbilical single-hole laparoscopic cholecystectomy. Compared with traditional single-hole laparoscopic cholecystectomy, this method added a 1.8 mm auxiliary stretch hole, and its postoperative cosmetic effect was consistent with that of conventional single-hole laparoscopic cholecystectomy, but greatly reduced the operation time and difficulty. This video shows the operation process of T-type memory wire assisted traction for exposed transumbilical single-hole laparoscopic cholecystectomy independently developed by the author's team.
