Exploring the secret of minimally invasive surgery: how do large tumors get out of small holes?

How is minimally invasive surgery done? Professor Shi Yongpeng, a well-known expert in endoscopic minimally invasive surgery at the Ambassador Institute of Minimally Invasive Surgery, explained that minimally invasive surgery is the same as traditional surgery. After all the preoperative examination, diagnosis, surgical planning, etc. After completion, all surgical methods after anesthesia are completely different from traditional open surgery. Mainly reflected in the following aspects: First, laparotomy means that the doctor's hands do not enter the uterine cavity and abdominal cavity, and do not touch human organs such as uterus. So, how to use a scalpel for surgery? The answer is to drill 3-5 small holes with a few millimeters in the abdomen and insert rod-shaped surgical instruments to form a channel, so that brand-new surgical instruments such as endoscope, grasping forceps, electrocoagulation knife, rotary cutter, suture, suture needle and irrigator can enter and exit through these set channels to complete a series of actions such as grasping, lifting, washing, lifting, peeling, cutting, taking and sewing to complete the operation. Second, new equipment and new operation methods. The way of minimally invasive surgery through the abdomen determines the difference of surgical instruments. The surgical instruments used in minimally invasive surgery are a brand-new and perfect system, which is mainly reflected in the following aspects: the surgical instruments are all rod-shaped, including grasping forceps, cutting knives, irrigators, electrocoagulation knives and so on. They are all miniaturized and placed at the tip of the operating lever, which is completely intelligent control. Doctors can accurately control grasping forceps, cutting knives, irrigators, electrocoagulation knives, etc. By manipulating the handle in their hands or the control switch placed under their feet. Thirdly, it can be seen that since the operation is carried out through the abdomen, how does the doctor look at the operation site? The following are the key technologies: endoscope and monitor. Endoscope is actually an ultra-miniature high-definition camera, which uses a cold light source to take pictures. The lens is only the size of mung bean, and the shot picture is directly displayed on the monitor in front of the doctor through the data cable. Therefore, the whole minimally invasive surgery is completed by the doctor looking at the clear display screen. Of course, these two devices are very smart, and the picture can be enlarged several times at will to see more clearly. The above three key technologies have solved the problems of laparotomy, vision and operation, and completely covered the technical elements of gynecological surgery. With the innovation of technology, the advantages of minimally invasive surgery are very obvious, which can double the picture, which means that surgery can be done faster and more finely; No laparotomy means less injury, no infection, avoiding adhesion and leaving no scars, which means reducing pain, greatly shortening hospitalization time and saving expenses. How to take out a big tumor from a small hole of several millimeters? How to take out a large tumor with a diameter of several centimeters or dozens of centimeters through a small hole with a size of several millimeters? The method is to crush it and take it out. When the doctor completely peels off the tumor, he will grasp the tumor with the grasping forceps and then start the rotary cutting with the rotary cutter. The selected myoma will be taken out of the body from the pipeline of the rotary cutter like water in the pipeline.
