Our group previously demonstrated that a transperitoneal abdominal wall block can be performed with simultaneous extracorporeal ultrasound confirmation of injectate spread. Here, we report a purpose\u2010designed laparoscopic injection needle to standardize this internal approach in RPS. The single\u2010use device has an 800\u2009mm flexible shaft, a 25\u2010gauge needle, and an adjustable tip protrusion (2\u20137\u2009mm), enabling insertion through 3 or 5\u2009mm ports while maintaining pneumoperitoneum. The target layer is identified from the peritoneal side; correct plane entry is confirmed by visual \u201ctenting\u201d and controlled hydrodissection; and local anesthetic is delivered while observing real\u2010time tissue distension. The technique was integrated into reduced\u2010port transabdominal preperitoneal (TAPP) inguinal hernia repair without workflow interruption.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This device provides a practical method to perform abdominal wall nerve block under direct visualization in RPS, with depth control tailored to abdominal wall thickness.
