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, 5.6 mm; length, 2500 mm) and inner rod, and is made in a similar manner to a drinking straw. Therefore, the manufacturing costs are low. To use the device, folded mesh is placed inside it with a grasper before surgery. The device is then inserted through the trocar, and the mesh is pushed out by the inner rod and applied. The folded mesh extrudes smoothly pubis side to lateral side along the inguinal curve. It reinforces the area without any contamination and expands in a manner that makes it easy for the surgeon to place and fix the mesh. Our device allows mesh to be applied smoothly, comfortably, and economically, and it may reduce the risk of infection.
