单孔腹腔镜腹股沟疝修补术以“无瘢痕”美容优势成为疝外科临床热点，而单孔腹腔镜的“轴向视野”引发的“筷子效应”、视野压缩等操作难题，成为该技术推广的瓶颈。建议采取经脐“兔唇”样切口结合脐筋膜平面的单孔穿刺布局方案。术中可采取“双手器械以前后关系替代左右距离”策略，联合腹腔镜镜头角度和位置调整，以解决“筷子效应”带来的操作困难；采用笛卡尔坐标系明确镜头与器械的分离成角关系（即“单极操作画面”）；单手缝合腹膜的核心技巧是精准把控缝针，务必使其始终挂在腹膜上不脱离视野，从而保证夹持与松开的连贯动作高效完成缝合。

Single incision laparoscopic transabdominal preperitoneal (TAPP) repair for inguinal hernia has become a focus in minimally invasive hernia surgery due to its scar-free cosmetic advantage. However, the inherent axial vision in single incision laparoscopy leads to operative difficulties such as the “chopstick effect” and visual compression, which constitute the bottleneck for the popularization of this technique. It is recommended to adopt a single-incision trocar placement via the transumbilical “hare-lip” incision combined with the umbilical fascia plane. By adopting the strategy of “replacing lateral distance with the anteroposterior movement of bilateral instruments” during the operation, combined with adjustments of the angle and position of the laparoscopic lens, the operational difficulties caused by the “chopstick effect” are resolved. The Cartesian coordinate system can be adopted to clarify the separated angular relationship between the lens and the instruments (i.e., the “unipolar operating view”). The core technique of one-handed peritoneal suturing is precise control of the needle, ensuring that it always remains engaged in the peritoneum without leaving the field of view, thereby allowing the coordinated actions of grasping and releasing to be performed smoothly for efficient suture closure.
