Minimally invasive surgical techniques

At present, minimally invasive surgery accounts for more than half of all surgical procedures, with large general and specialized hospitals accounting for more than 70 percent. So, what is minimally invasive surgery? Compared with traditional surgery, it is much more expensive, where exactly is it? Nowadays, the popular minimally invasive surgical techniques mainly include: 1) lumpectomy, 2) endoscopic surgery, 3) interventional techniques. Laparoscopic surgery technology: It is a minimally invasive technology widely used in general surgery urology thoracic surgery pediatric surgery gynecology surgery with laparoscopy as the main body. Compared with the traditional concept of “the larger the incision, the clearer the exposure”, minimally invasive surgery is characterized by miniaturization of the incision, magnification of the exposure and precision of the operation. It is a transitional stage from invasive surgery to non-invasive surgery. It is mainly due to the rapid development of modern optical fiber electronic technology, precision instrumentation and remote transmission technology, and is widely used in clinical practice. The computerized robotic surgery now being carried out in the clinic is another milestone in the development of laparoscopic surgery. The combination of computerized remote control robot and new generation of broadband network has made remote surgery a reality. In other words, surgical specialists can be invited to perform precise and difficult surgeries for patients in another city several thousand kilometers away from the north. At the same time, with the development of image reconstruction technology and similar surgery operation technology, for a patient who is about to be operated, CT and MR examination will be conducted first, and then the image will be reconstructed to show the similar anatomy of the patient’s organs, so that the surgeon will be able to repeatedly simulate the operation on the computer simulator before the operation for him, so as to choose the best operation route and operation mode and minimize the risk of real operation. This allows the surgeon to select the best surgical approach and surgical procedure to minimize trauma and malpractice during the real surgery. However, it is foreseeable that with the development of physicochemical and biological technology it will eventually be replaced by non-invasive surgery, and it is likely that human beings will be able to combine endoscopic technology, which can reach all parts of the body through natural openings and orifices, with genetic technology, molecular bio-immunological technology, and physicochemical technology to perform various non-invasive surgeries without the need for general anesthesia; Micro camera and digital-to-analog converter; monitor; cold light source; video recorder and image storage system; CO2 pneumoperitoneum system; surgical instruments used under laparoscopy; disposable instruments and consumables needed for the surgery. The basic way of TV laparoscopic surgery: 1. The pneumoperitoneum is established by injecting C02 gas into the abdominal cavity, so that the abdominal cavity is expanded and the stomach and intestines are squeezed backward to form sufficient visual and operating space for the observation and operation of the slender laparoscopic view tube and surgical instruments in the abdominal cavity. 2, after the establishment of pneumoperitoneum, the first 10mm puncture hole (Toucar) channel was established at the umbilical rim, and the laparoscopic view tube was placed to explore the whole abdominal cavity, so as to understand the condition again under real direct vision and decide whether to operate and the mode of operation. After determining the surgical method, several perforated channels are established in appropriate parts of the abdominal bikini under laparoscopic surveillance, and the corresponding surgical instruments are placed and the operation can be started. 3, the main difference between surgery and traditional open surgery is: hemostasis: mainly rely on electrocoagulation (hook and shovel bar) ultrasonic knife ligation speed of thermal coagulation and titanium clips bioabsorbable clamping ring set ligature automatic cutting anastomosis appropriate combination of sutures. Incision and separation: mainly rely on ultrasonic knife combined with the use of electrocoagulation 〈hook and shovel scissors〉 Suturing: mainly rely on automatic cutting closures appropriately combined with needle and thread sutures. Removal of specimen: mainly by dilating the original puncture hole abdominal jaws otherwise small incision left colorectal surgery can be removed by dilating the anal canal, the specimen is too large can be combined with a tissue crusher in the specimen bag to crush the specimen and remove it. The reason for the high cost of TV laparoscopic surgery and the low reimbursement by medical insurance is that there are many disposable imported consumables used in the operation, and although domestic generic consumables are gradually being used in the clinic, the price is still high. Ultrasonic knife head 〈6000 yuan a 8000 yuan〉 automatic cutting closures 〈cutting closures 6000 yuan or so each nail bin 2000 yuan a 4000 yuan〉 hemostasis with bioabsorbable clip each 〈100 yuan a 200 yuan〉 dosage is larger. Disposable puncture Toucar (imported set of 4 about 8000 yuan). The amount of consumables that must be used for each operation determines the cost of the operation in addition to the cost of anesthesia, and the cost of consumables, especially imported consumables, is basically not reimbursed by medical insurance. The main minimally invasive surgeries suitable for TV laparoscopy are: diagnostic laparoscopic exploration of the abdominal cavity cholecystectomy (gold standard surgery) appendectomy repair of gastrointestinal perforation surgery of various large benign cysts in the abdominal cavity esophageal reflux Nissen surgery small bowel resection colorectal tumor surgery hernia reconstruction and repair splenectomy With the advancement of laparoscopic technology and the improvement of the operating skills of the surgeon, especially the newly developed With the advancement of laparoscopic technology and the improvement of surgeons’ skills, especially the application of newly developed surgical instruments and consumables in clinical practice, the following procedures have been gradually introduced: major gastrectomy, radical gastric cancer resection, biliary-intestinal anastomosis, pancreatic tail resection, partial hepatic wedge resection. The procedures that are still in the exploratory stage are: pancreaticoduodenectomy, standard hepatic lobectomy, hemangioma resection and various diversion procedures. Currently, with the promotion of 3D and 4K laparoscopy and the popularity of clinical applications, the surgical exposure is clearer and the anatomical levels are more easily separated. The clinical application of surgical robots has made the operation more accurate and the cooperation between the surgeon and the assistant more relaxed and pleasant, but the cost of robotic surgery is expensive, and the cost of surgery alone (excluding consumables) is about 50,000, which is not covered by medical insurance and is difficult for general patients and families to afford.
