Currently, domestic open surgery for children’s hernias usually involves an incision of 2-3 cm, leaving a dominant scar in the inguinal area after surgery. With the extensive development and improvement of minimally invasive laparoscopic surgery, minimally invasive surgery for children’s hernia has been developed from 3 holes to 2 holes, although the wound is smaller than the open surgery, but in the navel next to the postoperative period will still leave 1-2 0.5cm poke card hole scars, in order to be more traumatized, postoperative scars do not show, in recent years, began to the development of the single-hole technology, but due to the operation of one-handed operation, the operation of a certain degree of difficulty has not been able to promote, a number of hospitals All are just picking individual simple inguinal hernia to do, the completion rate is below 5%. In order to overcome this bottleneck, Dr. Liu Sujun developed a miniature needle forceps (diameter of only about 0.15 cm), dedicated to children’s single-hole laparoscopic technique, from the lower abdomen directly into the needle forceps, without the need to poke the card, and therefore does not leave a scar after surgery. After the invention of needle clamp has been done 500 cases, the completion rate of 100%, this new single-hole laparoscopic technology wide indications, can be used for all children’s hernia, breaking the wandering for several years has not been able to widely promote the single-hole laparoscopic technology, which is currently the most cutting-edge single-hole laparoscopic minimally invasive technology in the international arena. Its advantages are remarkable: wide indications, shorter operation time (a few minutes), less trauma, less pain, faster recovery, no scar, no anti-inflammatory drugs, ability to eat and get out of bed as soon as you wake up from anesthesia, discharge on the same day, and many other advantages. Needle clamp for single-hole laparoscopic surgery, the first in China, has not yet seen similar reports. She said, children’s inguinal hernia is a common disease, the incidence rate of 1% -4%, premature and low-birthweight babies can be as high as 30%, children’s hernia is a congenital disease, ranked first in all congenital defects. The herniated contents can be the intestines, the greater omentum, or in girls, the fallopian tubes or ovaries. If treatment is delayed, it may affect the child’s genital development and physical and mental health, and can be life-threatening in cases of incarceration and strangulation. Although hernia treatment has a history of hundreds of years, so far, surgery is still the only effective treatment for hernia in children over 1 year old. Currently, there are two surgical methods, one is open surgery and the other is minimally invasive laparoscopic surgery. Because laparoscopic surgery has many advantages over open surgery, it is now widely practiced at home and abroad. However, single-port minimally invasive laparoscopic surgery is the only conventional surgery for children’s hernia in Chaoyang Hospital. This hernia treatment technology has strengthened the hospital’s leading position in hernia treatment in China. In 2007, Chen Jie, the current Director of Hernia and Abdominal Wall Surgery of Chaoyang Hospital West, created the first first-level department of hernia and abdominal wall surgery in China, which has developed into the largest and most powerful professional team in China, with a group of doctors performing the most hernia surgeries and the most authoritative technology in China.
