Usefulness of a novel, slim long syringe-like device for applying surgical mesh through a 5-mm trocar.

We developed a device for introducing surgical mesh through a 5-mm trocar during transabdominal preperitoneal hernia repair. This device is like a slim long syringe; it has a polypropylene outer sheath (outer diameter, 5.8 mm; inner diameter, 5.

A novel procedure for introducing large sheet-type surgical material with a self-expanding origami structure using a slim trocar (chevron pleats procedure).

Background: Large sheet-type surgical materials (e.g., absorbable hemostat, adhesion barrier membranes, and flat surgical mesh) are difficult to introduce into a corporeal cavity using a 5-mm trocar; however, laparoscopic surgeries that use mainly 5-mm trocars are increasing.
