阑尾切除术,一般采用斜切口,现介绍一种简单、损伤腹壁神经血管较少的入路。一、半月线的局部解剖1.半月线的表面投影和定位。腹肌发达的人,每侧腹直肌的外侧缘在腹壁体表都有一个纵向弓形的浅沟,称腹直肌旁沟(外侧沟)。其下为半月线,此线从耻骨结节开始上行,经过脐与髂前上棘的中点,止于第九肋软骨,腹内斜肌腱膜沿此线分成腹直肌的前后鞘。2.半月线的构成与局部解剖。腹直肌鞘 Appendectomy, the general use of oblique incision, is now introduced a simple, less invasive abdominal veins less access. First, the half-moon line of the local anatomy 1. Half moon line surface projection and positioning. Abdominal development of people, each side of the lateral rectus abdominis lateral abdomen in the body surface has a longitudinal arched ditch, called the rectus abdominis (lateral ditch). The next half-moon line, this line from the pubic nodules up, through the umbilical and anterior superior iliac spine midpoint, ending in the ninth costal cartilage, abdominal oblique aponeurosis along the line along the line into the rectus abdominis sheath. 2. Half Moon line composition and local anatomy. Rectus sheath
