After entering the new century, there is no doubt that it has made rapid progress not only in science and technology, but also in medicine. Today, with the rapid development of science and technology, the development of surgery must be the trend of minimally invasive, accurate and rapid rehabilitation. Compared with the current standard surgery, minimally invasive surgery has lighter pain, better internal environment stability, more accurate surgical effect Shorter hospital stay and better psychological effects are widely accepted by more and more patients and their families. Laparoscopic surgery is a typical representative of minimally invasive surgery, especially 4K laparoscopic minimally invasive surgery.
In recent years, our company has developed 4K ultra-high definition laparoscopic system, and has successively completed a series of complex and difficult minimally invasive operations such as laparoscopic radical resection of rectal cancer, laparoscopic radical resection of colon cancer, laparoscopic gastrectomy, laparoscopic repair of esophageal hiatal hernia, laparoscopic cholecystectomy / choledocholithotomy, endoscopic radical resection of thyroid cancer in customer hospitals. The operation is smooth and the operation effect is satisfactory.
Based on the traditional high-definition laparoscopic system, 4K laparoscopic imaging technology provides a more high-definition and real surgical field of vision, makes up for the shortcomings of previous conventional laparoscopy in image description, enhances the description of the details of the surgical field, and presents a clearer and real surgical field of vision better than that seen by the naked eye on the large screen, which is a "new favorite" for the development and innovation of minimally invasive surgical laparoscopic vision platform.
Compared with the traditional HD display, 4K laparoscopic system has the following characteristics and advantages:
(1) 4K laparoscopic system monitors are larger, usually 55 inches (16:9) and above. As the screen size changes, the optimal viewing distance between the surgeon and the screen also changes.
(2) 4K laparoscopic system can provide clearer surgical vision and vivid pictures. Its significantly enhanced authenticity and sufficient magnification can bring better positioning and orientation for the operator, so as to improve the precision of the operation.
(3) 4K laparoscopic system can accurately grasp the membrane anatomy and has outstanding advantages.
(4) The delicate anatomical imaging under 4K HD imaging technology can help to improve the degree of anatomical identification of the operator and improve the accuracy of the operation, so as to complete the fine anatomy more smoothly. For example, the recognition of nerves, blood vessels, mesangium, lymph and adipose tissue in the visual field of laparoscopy is increased. On this basis, fine anatomical dissociation can reduce intraoperative bleeding, protect important nerve functions, and accurately clean the scope and boundary of lymph nodes.
(5) The amplification advantage of 4K laparoscope can effectively alleviate the degree of eye fatigue compared with traditional HD laparoscope.
