Description
Technical field
The present invention relates to a kind of medical embedded apparatus, more specifically, relate to the implantation instrument of a kind of anti-gastroesophageal reflux.
The implantation instrument of the present invention passes through laparoscopic surgery, is around to outside patient's lower esophageal sphincter, reaches to strengthen lower esophagus and include about
Flesh making capacity, plays the effect resisting gastric content reflux.
Background technology
Gastroesophageal reflux disease (GERD) refers to that the too much content reflux of Stomach duodenum enters esophagus and causes the heartburn disease that Dengs
Shape, and may result in the histologic lesion beyond the esophagus such as esophagitis and pharynx, larynx, air flue.Gastroesophageal reflux disease is in western countries very
Common, in crowd, about 7%～15% has a gastroesophageal reflux symptom, falls ill and increases with the age and increase, and 40～send out for peak for 60 years old
At the sick age, men and women falls ill zero difference, but has reflux esophagitis person, and male is more than women (2: 1 to 3: 1).Along with Chinese citizen
The raising day by day of living standard, the continuous westernization of life style, the raising the most year by year of the sickness rate of gastroesophageal reflux disease, patient's
Quantity will increase year by year.Meanwhile, along with the raising of living standards of the people, the requirement to quality of life also improves constantly, for
The demand of the gastroesophageal reflux disease that radical cure affects quality of life for a long time also will constantly expand and improve.Chinese Medical Association's disease for digest
Credit can add up display, and China's gastroesophageal reflux prevalence is 5.77%.Big city prevalence is the highest, Xi'an 16.98%,
Beijing 10.19%, Shanghai 7.7%, Zhejiang 7.28%.Also there is not good apparatus to treat gastroesophageal reflux disease at present, although
Unisem fundoplication, Unisem fundoplication is had to combine esophageal hiatus hernia repair, radio-frequency (RF) therapy three kinds treatment stomach esophagus
The operation of reflux disease, but postoperative it is often accompanied by complication, postoperative life is made a big impact, former capital does not recommend this type of hands
Art is treated.Abroad, through research and development for many years, existing similar products overcome disadvantage mentioned above, and such as, patent name is " treatment
Esophageal sphincter apparatus " United States Patent (USP) US 7,695,427 B2 disclose a kind of apparatus treating gastroesophageal reflux disease, a string
Magnetic pelletron, by peritoneoscope Minimally Invasive Surgery, two ends connect into a ring closed from beginning to end, are looped around patient's esophagus
Outside lower sphincter.But its shortcoming is: first, the ring of formation is round, it is impossible to well paste with outside inferior esophageal sphincter
Closing, when patient swallows food, esophagectasis can produce friction with apparatus, causes patient uncomfortable, patient can be caused what is more to eat
The symptom such as inflammation outside the lower sphincter of pipe；Secondly, two ends connect inconvenience from beginning to end, are unfavorable for that doctor operates, add operating time；
3rd, the pelletron of this magnetic implants after a period of time, and the gap between magnetic bead and adjacent magnetic bead can be by tissue bag
Wrap up in and fill, once find that patient is not in good time, take out relatively difficult.
