The development of laparoscopy, like the development of all new technologies in medicine, has taken place over a long period of time. The use of a speculum to peer into the rectum was described as early as BC, when people longed to see the various organs and tissues in the dark body cavity with a view to making a definitive diagnosis of disease. The laparoscope is a type of endoscope used for direct visualization of organs within the abdominal cavity. The development of minimally invasive laparoscopic techniques has gone through nearly a century of history, from the use of candlelight illumination for abdominal observation to the current use of laparoscopy to perform various surgeries. With the development of modern electronic information technology and light-guided process technology, laparoscopic minimally invasive techniques are gradually becoming a new paradigm for many surgical treatments. Some even predict that after the first 20 years of the 21st century, the vast majority of gynecological procedures can be performed lumpectively. Minimally invasive laparoscopic techniques matured in the 1980’s and 1990’s. In 1987, Mouret, France, first reported the televised laparoscopic cholecystectomy, which opened a new chapter of modern minimally invasive surgery, and in February 1991, Xun Zuwu performed the first laparoscopic cholecystectomy in China. The outstanding representative of modern minimally invasive surgical technology – TV laparoscopic technology, known in the medical field as the end of the 20th century photoelectric field of modern high technology and modern surgical science organic combination of a new technological revolution in the field of surgery, is a new milestone in the history of modern surgical development. First, the history of the development of gynecological laparoscopy gynecological laparoscopic technology is the continuous development of progress, it has gone through three stages: 1, pelvic laparoscopy 1901 Russian gynecologist D.O. ott also in the frontal mirror illumination incision of the vaginal vault into the cystoscope to observe the abdominal cavity of a woman. This was the first case of pelvicoscopy. 2. diagnostic laparoscopy In 1910 Jacobaeus.H.C first applied a trocar puncture needle into the abdominal wall and introduced air into the abdominal cavity through the trocar and then put in a cystoscope for examination. in 1944 Raoul Palmerjiang in France formally applied laparoscopy to the field of gynecology, examined a large number of infertile patients and developed a routine for laparoscopy. In 1963, a monograph was published to systematically introduce some relatively simple operations under laparoscopy, such as: tubal aeration and lavage; simple separation of visceral adhesions; tubal electrocoagulation sterilization; endometriosis electrocoagulation and electrocautery, etc. 3, surgical laparoscopy into the 70s due to the invention of cold light source, glass fiber endoscope, Germany Semm’s artificial pneumoperitoneum monitoring device – automatic pneumoperitoneum machine was introduced, so laparoscopic surgery has been developed with great enthusiasm. In 1980, Dr. Nezhat in the United States started to use television laparoscopy to perform surgery. In the late 1980s, Professor Kurt Semm of Germany invented and created many new surgical instruments and techniques. Such as: microscopic suturing instruments, flushing pumps, various clamps, scissors, combination crushers, cutters and so on. In 1988, Reich H performed the first laparoscopic total hysterectomy, and since then, the scope of gynecological surgery has become larger and larger, and almost 90% of gynecological surgery can be done laparoscopically. Laparoscopic surgery in China started late, and the first case of laparoscopic surgery was started in 1979 under the leadership of Jordan Phillips, the president of American Laparoscopic Association, and has reached the world advanced level since then. Second, gynecological laparoscopic surgery equipment Equipment includes: light source, conduction system and endoscope, TV camera system, inflatable device, i.e. CO2 pneumoperitoneum machine, electrosurgical instruments, irrigator and operating parts. Third, the operation skills of gynecological laparoscopy: 1, the basic operation skills: (1) position: gynecological laparoscopy using head low hip high 15-30 degrees position. (2) puncture site selection: the most common choice for the location of the mirror into the umbilicus, it is estimated that the pelvic mass is large or the surgical scar reaches the edge of the umbilicus, the upper edge of the umbilicus should be selected, this is the confluence of the groups of muscle fascia of the abdominal wall, the thinnest. (3) Pneumoperitoneum formation: After determining the puncture site, insert a 6mm pointed scalpel 2mm and then pick the skin upward about 1cm, hold and lift the abdominal wall with two scarf clamps next to the umbilicus so that the abdominal wall is away from the omentum and intestinal canal. The abdominal cavity was slowly entered and gas was injected. (4) Place the microscope to observe and decide on the procedure. (5) select the operation hole puncture. 2, electrosurgery application skills: electrocoagulation is one of the most common methods of hemostasis in laparoscopic surgery. It includes: cautery, coagulation, vaporization. 3. Operating techniques of microscopic suturing and knotting: Microscopic suturing is the most complete method of hemostasis and is extremely difficult for beginners. The first suture tying may take 20-30 minutes, but once you have mastered the technique of microscopic suture tying, laparoscopic surgery can be at your disposal. 4. Suture tying technique: The principle of suture tying is that slip knots are usually provided by the manufacturer with ready-made suture coils.
