Description
Technical field
The present invention relates to a kind of medical embedded instruments, more specifically, are related to a kind of implantation instrument of anti-gastroesophageal reflux.
The implantation instrument of the present invention is surrounded to by laparoscopic surgery on the outside of patient's lower esophageal sphincter, is reached the lower oesophagus of enhancing and is included about
Flesh making capacity plays the role of resisting gastric content reflux.
Background technology
Gastroesophageal reflux disease (GERD) refers to that the excessive content reflux of Stomach duodenum enters oesophagus and causes heartburn Deng diseases
Shape, and the histologic lesion other than the oesophaguses such as esophagitis and pharynx, larynx, air flue can be caused.Gastroesophageal reflux disease western countries very
Common, about 7%~15% has gastroesophageal reflux symptom, morbidity to increase with the age and increase in crowd, is sent out for peak within 40~60 years old
The sick age, men and women's morbidity indifference, but have reflux esophagitis person, male is more than women (2: 1 to 3: 1).With Chinese citizen
The increasingly raising of living standard, the continuous westernization of life style, the raising of the incidence of gastroesophageal reflux disease year by year, patient's
Quantity will increase year by year.Meanwhile with the improvement of people's living standards, the requirement to quality of life is also continuously improved, for
The demand of the long-term gastroesophageal reflux disease for influencing quality of life of radical cure also constantly will expand and improve.Chinese Medical Association's disease for digest
Credit can count display, and China's gastroesophageal reflux illness rate is 5.77%.The universal higher of big city illness rate, Xi'an 16.98%,
Beijing 10.19%, Shanghai 7.7%, Zhejiang 7.28%.There is not also good instrument to treat gastroesophageal reflux disease at present, although
There are three kinds of Unisem fundoplication, Unisem fundoplication combination esophageal hiatus hernia repair, RF therapy treatment stomach oesophagus
The operation of reflux disease, but it is postoperative be often accompanied by complication, to it is postoperative life make a big impact, former capital does not recommend such hand
Art is treated.At abroad, by research and development for many years, existing similar products overcome disadvantage mentioned above, for example, patent name is " treatment
7,695,427 B2 of United States Patent (USP) US of esophageal sphincter instrument " disclose a kind of instrument for treating gastroesophageal reflux disease, a string
Magnetic pelletron, by laparoscope Minimally Invasive Surgery, head and the tail both ends connect into a closed ring, are looped around patient's esophagus
On the outside of lower sphincter.But its shortcoming is that：First, the ring of formation is not round enough, can not be with good patch on the outside of inferior esophageal sphincter
It closes, when patient swallows food, mega-esophagus can cause patient uncomfortable, patient can be caused to eat what is more with instrument production friction
The symptoms such as inflammation on the outside of the lower sphincter of pipe；Secondly, the connection of head and the tail both ends is inconvenient, is unfavorable for doctor's operation, increases operating time；
