The history of endoscopic surgery.
In the 50s of the 20th century, endoscopic surgery began to be widely used in the fields of digestive system, respiratory system and urinary system. At that time, the endoscopic surgical equipment was mainly fiber-optic endoscopes and rigid endoscopes with large diameters.
In the 70s of the 20th century, with the development of electronic technology, a new type of endoscopic surgical equipment appeared - electronic endoscope. This device uses electronic photosensitivity technology instead of optical fiber to transmit images, which greatly improves the clarity and resolution of the image.
In the 80s of the 20th century, flexible endoscopes that can be bent appeared, which can be bent and rotated in the human body, which is convenient for doctors to observe and operate. At the same time, a new type of endoscopic surgical equipment has emerged - endoscopic surgical robot. This device can be operated surgically through joysticks and handles, reducing the flutter of the doctor's hand and improving the precision and safety of the operation.
At the beginning of the 21st century, with the continuous development of minimally invasive surgical techniques, endoscopic surgical equipment is also constantly updated and improved. A new type of endoscopic surgical device has emerged - the single-port laparoscopic surgical system. This device requires only a small hole to complete the surgery, reducing the surgical incision, shortening the recovery time, and improving the cosmetic results of the surgery. In recent years, with the development of artificial intelligence technology, endoscopic surgical equipment has also begun to become intelligent. Intelligent endoscopic surgical equipment can identify diseased tissues and organs through computer vision and machine learning and other technologies, and assist doctors in making accurate diagnoses and solutions. In conclusion, the development of modern surgical instruments has promoted revolutionary changes in the field of surgery, and endoscopic surgery is one of the important branches in modern surgery. The development process of endoscopic surgery related equipment has gone through different stages such as fiber optic endoscope, electronic endoscope, flexible endoscope, endoscopic surgical robot, single-port laparoscopic surgical system and intelligent endoscopic surgical equipment, which continuously promotes the progress and innovation of endoscopic surgery technology. The development of these devices has greatly improved the accuracy, safety and operability of endoscopic surgery, and brought more high-quality and safe medical services to patients.
4K endoscopic camera system.
Resolution and contrast enhancements. Traditional HD camera systems have a resolution of 1080p (1920 1080 pixels), while 4K camera systems have a resolution of 2160p (3840 2160 pixels), so 4K systems provide greater image detail and clarity. Studies have shown that when performing a gallbladder removal surgery using a 4K camera system, doctors are able to identify gallbladder anatomy and lesions more accurately, helping to avoid false cuts and damage to surrounding tissues.
Improvement in surgical outcomes. Zhang et al. compared the outcomes of laparoscopic colorectal surgery using 4K and traditional high-definition (HD)** systems, which covered all patients who underwent laparoscopic colorectal surgery in April 2016 to June 2021, and the results showed that intraoperative blood loss was significantly reduced in the 4K group, although there was no difference in the amount of blood transfusion required between the two groups; However, postoperative complications were similarly proportional between the two groups, but the incidence of ascites effusion, reoperation, and postoperative urinary tract problems was significantly higher in the HD group, suggesting that the 4K imaging system provided better surgical outcomes in reducing intraoperative blood loss and postoperative complications.
Postoperative recovery and readmission rates. In gallbladder resection surgery, patients using 4K camera system have significantly reduced postoperative pain and shortened recovery time, Zhuang Haiwen et al. (2021) The short-term clinical effect of using 4K ultra-high-definition laparoscopic system and traditional 2D high-definition laparoscopic system in rectal cancer surgery, the study showed that compared with the 2D group, the operation time in the 4K group was shorter and the amount of blood was less, and the results of this study showed that the 4K endoscopic camera system has obvious advantages in endoscopic surgery, Its high resolution and contrast enhance image quality, allowing physicians to perform surgical procedures and lesion identification more accurately, improving surgical outcomes and post-operative recovery of patients.
