一种腹腔镜下腹股沟疝气的3D解剖修补补片A laparoscopic 3D anatomical patch for inguinal hernia repair

技术领域technical field

本发明涉及疝气补片技术领域，具体为一种腹腔镜下腹股沟疝气的3D解剖修补补片。The invention relates to the technical field of hernia patch, in particular to a laparoscopic 3D anatomical patch for inguinal hernia repair.

背景技术Background technique

腹股沟区域的耻骨肌孔属于解剖学上的薄弱部位，且这个区域仅有腹横筋膜承受腹部内压，又存在精索或圆韧带及股血管经过，故此区域在人体中最易发生疝气。The pubic foramen in the groin area is an anatomically weak part, and only the transversalis fascia bears the intra-abdominal pressure in this area, and the spermatic cord, round ligament, and femoral blood vessels pass through, so this area is the most prone to hernia in the human body.

对于腹股沟区域疝气的治疗，目前提倡无张力微创手术修复，具有更低复发率和更快的术后恢复的优点。但现今市面上传统的疝气补片，都需要对其形状尺寸进行裁剪后使用，需要额外的固定并难以通过套管针进行手术；裁剪产生的毛边对于腹膜、内脏可能产生伤害，产生并发症，甚至疝气复发。For the treatment of hernias in the inguinal region, tension-free minimally invasive surgical repair is currently advocated, which has the advantages of lower recurrence rate and faster postoperative recovery. However, the traditional hernia mesh on the market today needs to be used after cutting its shape and size, which requires additional fixation and is difficult to operate with a trocar; the burrs produced by cutting may cause damage to the peritoneum and internal organs, resulting in complications. Even hernia recurrence.
