In 2014, Shanghai Yuanda Cardiothoracic Hospital successfully performed the first 3D thoracoscopic heart valve replacement surgery in China, and recently introduced the German STORZ 3D thoracoscope equipment, adding “3D” wings to minimally invasive surgical procedures for cardiothoracic diseases. What is the role of 3D thoracoscopy? The 3D thoracoscopy system is similar to the robotic surgical imaging system, restoring the surgeon’s natural three-dimensional vision and depth perception, reducing anatomical difficulties and the possibility of post-operative complications for patients, improving surgical anatomy, cutting, grasping, anastomosis, suturing, hemostasis & degree and overall surgical efficiency, and also has a “sense of touch” that robotic surgery does not have. “. In addition, unlike ordinary civilian 3D technology, medical 3D, which can make the subject’s reproduction close to 100%, and is less likely to make people feel dizzy. In addition, 3D technology can also reduce the operating time by one-third, thus reducing the pain of patients. Even as the cardiothoracic diseases such as delicate and complex surgery, doctors with the help of 3D glasses, only minimally invasive can be carried out, while the patient’s organs and lesions are presented on the monitor three-dimensional picture, a clear perspective, the doctor’s line of sight between the patient’s organs, feel like opening the chest cavity “direct vision” under the same surgery, so that The operation & degree and efficiency are improved comprehensively, and the patient’s postoperative recovery period is also greatly shortened. The treatment of cardiothoracic diseases has entered the era of 3D minimally invasive The traditional open-chest surgery for cardiothoracic diseases is characterized by large incision, trauma, bleeding, pain and slow recovery, while minimally invasive surgery has gradually become the development trend of surgical treatment with its small incision, trauma, micro bleeding, pain and fast recovery. The original thoracoscope used is two-dimensional and has no three-dimensional sense. Internationally, lumpectomy minimally invasive cardiothoracic surgery has entered the 3D era, and at present, not many domestic can apply 3D thoracoscopy to both cardiac surgery and thoracic surgery. As a newly developed lumpectomy technology, 3D thoracoscopic surgery has better visual effect and higher surgical safety, and some shortcomings in traditional lumpectomy are gradually being improved. Just like 3D movies, with the 3D thoracoscopy system, the two-dimensional image becomes three-dimensional, the magnification of the operating field is greater, and the surgeon is able to see the three-dimensional structure of the heart more finely and clearly, and the positioning is more accurate, which helps a lot in the operation, and the surgical result is naturally better! What diseases are they used for? 3D thoracoscopy is widely used, and it can be used in the surgical treatment of congenital heart disease, heart valve disease, atrial fibrillation, coronary heart disease, lung tumor and other cardiothoracic diseases. Of course, patient safety, efficacy and better final prognosis are still the better and higher evaluation criteria in the selection of surgical procedures. With the development and progress of science and technology, the concept of “minimally invasive” has penetrated into all fields of surgical procedures.
