In recent years, due to the boom of laparoscopic surgery, laparoscopic surgery has developed greatly, and the vast majority of intra-abdominal organ surgeries can be performed by applying laparoscopic surgery. With the improvement of surgical techniques, the surgical instruments have evolved to be more miniaturized and are now developed to the stage of mini-laparoscopic technique. Relative to the traditional laparoscopic application of 10mm, 12mm instruments, or even hand-assisted laparoscopic technology, mini-laparoscopic instruments are more fine and small, generally use 5mm and the following instruments, the image is that the original need to play finger-thick orifices, and mini-laparoscopy as long as the ballpoint pen core thick orifices can be played, which brings the benefits of the operation is the incision is more small, purpura is less obvious, postoperative pain is more mild, but the requirements for the operation is more than the incisions. The benefits are smaller incisions, less visible purpura, and less postoperative pain, but it requires higher surgical proficiency and higher surgical skills on the part of the surgeon. The main indications for minilaparoscopic surgery are surgery without specimen or small specimen. The main indications for urology surgery are: 1) abdominal cavity exploration surgery, 2) high spermatic vein ligation, 3) ureteral stone or ureteral stenosis surgery, 4) renal cyst decortication, 5) adrenal gland surgery, etc. Minimally invasive urology group of Jining First People’s Hospital, on the basis of many years of minimally invasive surgery, carried out mini-laparoscopic surgical treatment of urological diseases, and it was observed that the operation time was roughly the same as that of traditional laparoscopic surgery, because the mini-laparoscopic incision suture was simpler or did not need to be sutured, and the time of surgical sweeping work was shorter. The surgical results were the same as those of conventional surgery. Postoperative patient pain was significantly reduced. As summarized by the postoperative follow-up, the minilaparoscopic benefit is significantly better than conventional laparoscopic surgery when the indications are selected appropriately. In another picture, a patient with diffuse dermatosis was operated with a perforation in a seam, which would have left no place for an incision if conventional surgery had been performed.
