Increase the difficulty of surgery: The main disadvantage of single-hole laparoscopic surgery is the increased difficulty of surgery. In single-hole laparoscopic surgery,Single Port Laparoscopic because all the operating instruments enter through a single channel, the operating space is narrow, the instruments cross each other,Single Port Laparoscopic and it is easy to fight, which is called the "chopstick effect". In particular,Single Port Laparoscopic the suturing operation under the microscope can only be performed with one hand most of the time.

High demands on the surgeon: because the operating instruments are often on the same parallel line with the lens,Single Port Laparoscopic the triangle area of the conventional laparoscopic surgery disappears,Single Port Laparoscopic requiring the operator to re-feel the position of the instruments and the depth of anatomy,Single Port Laparoscopic and the operating accuracy is reduced. Intraoperative instruments are also easy to block the lens. Sometimes in order to take into account the operation of the instrument,Single Port Laparoscopic the lens must make appropriate concessions, making it difficult to obtain the best surgical field of vision.

Therefore, single-hole laparoscopy requires higher skills and proficiency of the operator,Single Port Laparoscopic making it more difficult and longer to operate,Single Port Laparoscopic which also limits the wide application of single-hole laparoscopy to some extent.
