Compared with traditional open abdominal surgery, laparoscopic minimally invasive surgery is more minimally invasive and safer. It has high-quality features such as aesthetics, less postoperative pain, and minimizes the impact of surgery on patients. It has obvious advantages in reducing postoperative incision pain and abdominal wall paresthesia, and shortens the postoperative recovery period of patients.
目前在腹腔镜微创外科手术时，由于腔镜下微创手术的局限，特别是腔镜下微创外科手术的远端直肠，空间狭小，导致手术中操作难度加大，需要在下腹部增加微创切口使用其他辅助工具将患者腹腔部位的组织进行牵引、分开和托举，以使腔内切割吻合器较容易地夹持到组织最佳切割缝合位置，但这样操作比较繁琐、难度加大、增加患者痛苦、延长手术时间、增加手术成本，且手术视野存在一定局限性。At present, in laparoscopic minimally invasive surgery, due to the limitations of laparoscopic minimally invasive surgery, especially the distal rectum in laparoscopic minimally invasive surgery, the space is narrow, which makes the operation more difficult. Using other auxiliary tools to pull, separate and lift the tissue in the abdominal cavity of the patient in the wound incision, so that the endoluminal cutting and stapler can be easily clamped to the optimal position for cutting and suturing the tissue, but this operation is more cumbersome, more difficult, and It increases the patient's pain, prolongs the operation time, increases the operation cost, and has certain limitations in the operation field.
