The internal ring opening is usually referred to as the internal ring opening of the inguinal canal, and the internal buckle is located near the lateral aspect of the inferior artery of the abdominal wall, which is the location of inguinal hernia. At the lower edge of the abdomen, the inguinal canal exists, which is traveled by the male spermatic cord, the male ilioinguinal nerve, and other structures. The canal is enclosed by structures such as the tendinous membrane of the external abdominal oblique muscle, the inguinal ligament, and the transversus abdominis fascia, and lacks tissue sealing at its ends, forming a deep ring and a superficial ring. The deep ring is also known as the internal orifice of the inguinal canal. The internal orifice is essentially an oval hole formed by the transversus abdominis fascia, which is located lateral to the inferior artery of the abdominal wall, and can be positioned on the surface approximately one transverse finger above the midpoint of the line connecting the anterior superior iliac spine and pubic symphysis, a position that can vary depending on body size and other factors. Because the internal and external orifices lack muscular structures, they normally rely on intra-abdominal pressure for compressive closure to prevent inguinal hernia. When conditions such as non-occlusion of the sheath protrusion and muscle dysplasia in the inguinal region occur, an inguinal hernia may result. Prompt hospitalization is recommended for suspected inguinal hernia.
