【Laparoscopy】3D Laparoscopic Surgery
With the continuous development of three-dimensional imaging technology, its application in minimally invasive surgery has become increasingly widespread. Compared with traditional 2D laparoscopy, 3D laparoscopy can provide a three-dimensional sense of the surgical field of view and a sense of spatial depth for surgical operations, and make up for the lack of two-dimensional images in spatial positioning and identifying anatomical structures.
1.1 Visual field exposure technology under 3D laparoscopy As the current 3D laparoscopy works according to the 3D imaging principle, the position of most dual cameras is fixed. Therefore, in actual work, it is not possible to change the angle of view by rotating the angle of the lens section of a 2D laparoscope. In this case, when the target surgical field is blocked by other tissues, the anatomical structure behind it is difficult to reveal. The bendable high-definition 3D lens can make up for this deficiency. Studies have confirmed that the use of a flexible 3D lens in laparoscopic radical gastric cancer surgery is more conducive to lymph node dissection in the abdominal trunk area. The reason is that the flexible 3D lens can provide a larger field of view to fully reveal the lymphatic fat behind the upper edge of the pancreas organization.
Due to the imaging characteristics of the 3D laparoscopic system itself, most 3D laparoscopic lenses on the market currently have a concept of "comfort zone" or "stereoscopic window", that is, the distance between the observation object and the lens should be within an appropriate range, otherwise it will The 3D effect of the image is partially lost or causes visual discomfort. Therefore, when revealing the surgical field of vision, the hand mirror should pay attention to this objective problem, avoid the lens too close to the observation object, and reduce the loss of 3D effect.
1.2 3D laparoscopic surgical operation technology In recent years, high-quality RCT studies have confirmed that the application of 3D laparoscopy for basic surgical operation techniques has better training effects than 2D laparoscopy, which is mainly reflected in the shortened operation time, reduced operation errors, and precise operation Sexual improvement, etc. Other advantages are mainly reflected in the shortened movement trajectory of the equipment, the reduction of the number of repeated operations, and the faster movement of the equipment.
Therefore, 3D laparoscopic surgery is not limited to surgeons with rich experience in 2D laparoscopic surgery, but can be widely used in the training and practice of beginner surgeons, and it is expected to achieve multiplier results in shortening the learning curve.
