3D surgery makes surgeons more comfortable The advent of 3D surgery represents an ongoing innovation in medicine, as the first generation of stereoscopic laparoscopy required the surgeon to wear a head-mounted monitor, whereas now only a pair of lightweight polarized glasses is required. 3D surgery restores the advantages of natural vision, minimizing the risk of accidental damage to blood vessels, allowing surgeons to separate blood vessels, intestinal walls and even manipulate internal sutures with greater ease. It also facilitates cleaner lymphatic drainage and reduces the time required for each step, thereby shortening surgery time. For beginners in laparoscopic surgery, the application of 3D technology can provide better assistance in the transition from clinical anatomy to hands-on practice. 3D movies give the surgeon a unique immersive effect, and the most striking feature of 3D HD laparoscopy is that the surgeon knows the depth and the patient has fewer postoperative complications. This is because the surgeon needs to constantly correct for differences between the plane and reality during the operation of a conventional laparoscope. Even then, it is difficult to operate on organs that are deeply located and rich in surrounding vessels and nerves, and 3D HD laparoscopy compensates for these shortcomings. 3D laparoscopy is suitable for most general surgeries According to Prof. Chen Zhong, 3D laparoscopy can carry out all the diseases that can be treated by ordinary laparoscopic surgery, and the surgical results are better than those of conventional laparoscopy when the surgeon is skilled in 3D laparoscopy. Compared with conventional laparoscopy and open surgery, the advantage of 3D high-definition laparoscopic surgery is that it restores the three-dimensional surgical field of view in real vision and has a magnifying effect, which is equivalent to the doctor entering the patient’s body and can find the parts with lesions among various organs, and then perform precise resection and reconstruction. Therefore, the use of 3D laparoscopy can minimize the damage to blood vessels and nerves, reduce bleeding and surgical complications compared with conventional laparoscopy, and shorten the operation time. Especially for patients preparing for radical rectal cancer surgery, 3D high-definition laparoscopy can assist surgeons in achieving total rectal mesenteric resection and more accurate protection of the penile erectile nerve and urinary control nerve, further reducing the incidence of postoperative sexual dysfunction and urinary incontinence. For patients preparing for radical hepatocellular carcinoma surgery, 3D HD laparoscopy can help surgeons precisely remove the lesion and protect functional liver tissue.
