A tension-free repair patch for laparoscopic extraperitoneal inguinal hernia repair

Abstract

The present invention discloses a tension-free repair patch for laparoscopic extraperitoneal inguinal hernia repair, comprising an umbrella-shaped patch and a conical patch. The invention achieves reliable fixation of the patch to the tissue, reducing patch displacement, thereby improving surgical efficiency and safety, and reducing surgical difficulty and the incidence of complications. At the same time, it significantly reduces the separation range of the preperitoneal space, reduces trauma, and reduces the risk of postoperative bleeding at the surgical site.
