In recent decades, the main direction of surgical development is laparoscopic minimally invasive surgery: no need to open a knife, the doctor just open a few “holes” in the patient, put the laparoscope inside, and then through the image transmitted to the monitor, The surgeon operates the device to complete the operation. However, perhaps from the second half of this year, a 3D laparoscopic technique will be landed at a Chinese hospital. For Chinese doctors who are already skilled in 2D surgery for surgery, the 3D high-resolution laparoscopic system will be fully restored. Experience the stereoscopic surgery era with the naked eye.

"In the next 1 to 2 years, Chinese endoscopic surgery is about to enter the 3D era. This technology integrates optical and imaging medical technology and can completely present the stereoscopic perspective of the surgical field, allowing it to possess clinical surgery, observation and teaching. A special advantage.” Professor Yao Shuzhong, director of gynecology at the First Affiliated Hospital of Sun Yat-sen University of Medical Sciences, said that the application of 3D technology can provide doctors with more detailed and detailed anatomy, which can save operation time, improve surgical results, and bring convenience to remote consultations. In particular, the use of laparoscopic surgery in the discipline, or will be the first to use this technology in the discipline, has become an innovation in clinical surgery in China.

Stereoscopic field increases efficiency
It is reported that the traditional surgical open surgery is performed by the chief surgeon under the naked eye with various tools. Because the naked eye is open to the naked eye, the surgeon can naturally recognize the position, shape, and size of various organs and tissues of the patient. The spatial sensation is good and the anatomy can be easily identified; however, the open surgical incision is large, the bleeding is heavy, and the patient is injured. Larger, long hospital stay, slow recovery. The endoscopic minimally invasive surgery that emerged in the 1980s and 1990s has effectively improved the shortcomings of open surgery. It requires only a few millimeters of holes in the patient's body surface to extend the surgical instrument into the patient's body. Create surgery.

In endoscopic minimally invasive surgery, the surgeon uses a monitor to observe the patient's condition, but unfortunately, the flat monitor cannot provide a sense of three-dimensionality and space, so doctors need a lot of practice to master this technique. 3D laparoscopic technique is developed on the basis of ordinary laparoscopy. Through the 3D high-definition laparoscopic system, the laparoscopic transmission consists of two cameras that synthesize stereoscopic effects. The physician must wear 3D glasses for surgical operations.

At present, 3D laparoscopic techniques have been widely recognized internationally. Chang Qing, Hong Kong sales and marketing manager of international endoscopic manufacturer Carl Stouts Endoscope (Shanghai) Co., Ltd. disclosed that from June 2012, Carl Stouts 3D endoscopic camera system has been clinically tested in Hong Kong, mainly in obstetrics and gynecology, urology and general surgery. It is reported that the main application departments of the company in the domestic market will be basically the same with Hong Kong.

"Before 3D, everyone should know that surgical surgery has undergone traditional open surgery and the current common 2D (HD) minimally invasive HD surgery. 3D combines the advantages of both: on the one hand, can present the three-dimensional, traditional surgery. The sense of layering; on the other hand can reduce the physical trauma to the patient and make the surgery more accurate and safer.” Chang Qing special example, the doctor in the surgical process needs suture, we must accurately determine the depth of the suture position, this time 3D rendering The three-dimensional image is very helpful to the doctor's suture effect, this suture is more common in gynecology, urology.

"Surgical operation under 3D vision not only retains the features of traditional laparoscopic surgery with fine, minimally invasive surgery, but also has the advantages of high-definition stereoscopic vision, greatly improving the accuracy of the operation." Some hospital experts said that most of the current domestic The top three hospitals have been equipped with 2D HD minimally invasive surgery. If there is no need for excessive equipment replacement to achieve 3D advantages, I believe that in the future, many doctors will prefer 3D technology for surgical operations.

Better for doctors' technical training

Carl Stouts has developed a 3D endoscope system that can combine the advantages of open surgery and endoscopic minimally invasive surgery in response to market demands. This new surgical device combines a new-generation three-dimensional and minimally invasive endoscopic camera system. The method of use is exactly the same as that of the 2D endoscopic camera system, and 2D and 3D switching can be performed with one click. The difference is that the endoscope and camera of the 3D endoscopic camera system use an integrated design.

“The system we have developed has two independent sets of camera chips that can simulate the two eyes of a person through the principles of bionics.” Yang Lan, Project Marketing Manager of Carl Stouts Endoscope (Shanghai) Co., Ltd. introduced the reporter. In daily life, the sights seen by each of our left and right eyes are different. The left eye and the right eye respectively look at an object from different angles. The brain combines these two scenes to form a three-dimensional image. The picture allows us not only to see the color, shape and size, but also to determine the distance between the object and the context. The 3D endoscopic camera system uses two sets of camera chips to collect two angle images at the same time. After processing by a high-performance camera host, a realistic 3D image is presented on a dedicated 3D monitor to completely reproduce the patient's body. The real situation enables the surgeon to easily determine the level relationships between adjacent organs and tissues in the body and effectively increase the speed of tissue separation and resection, thereby improving the efficiency of surgery.

In addition, from the perspective of the advantages of 3D endoscopic technology, its camera system can also greatly shorten the surgeon's learning curve. Its use is similar to the existing endoscopic camera system, and does not require changes in the surgeon's surgical habits and operating procedures.

Chang Qing said that in Hong Kong, two hospitals that train surgeons, 3D will be of great help to some young doctors. Young doctors need to be able to master 2D minimally invasive surgery and require prolonged training before they can become skilled and use 3D surgery. The operative field is more three-dimensional and can help them master the technique of laparoscopic surgery in the shortest possible time.

"Using 3D technology, doctors perform operations on patients is as clear as Sun Wukong's being in the patient's stomach." A doctor who practices 3D laparoscopic techniques on the spot does not lose his humor.
