Description

Insert the duodenal sleeve that is used for the treatment of diabetes under scope
Technical field
The present invention relates to a kind of medical apparatus and instruments.
Technical background
At present, the annual neopathy rate of diabetes has reached 6.7% in China, the height in big city (Shanghai 10%).To reach 2-3 hundred million people in 2025.The operative treatment domestic, that the major measure of international treatment diabetes has Drug therapy and carried out in recent years, operation method comprises abdominal and laparoscopic surgery etc." gastric bypass operation " art formula in operation has become the goldstandard for the treatment of, the therapeutic effect Drug therapy that can match in excellence or beauty.Because operation can cause irreversible damage to have again some contingent complication to occur to human body, so that the restriction to some extent of carrying out.
Find in the retrieval to prior art:
[1] .KeithS.Gersin, MD, JenniferE.Keller, MD, Dimitrios Stefanidis, at IEEE Surgical Innovation, 14 (4): 275-278,2007 write articles " Duodenal-Je junal Bypass Sleeve:A Totally Endoscopic Device for the Treatment of Morbid Obesity " (duodenum _ jejunum detour sleeve pipe: treat the morbid obesity endoscopic assistance fully for one) Deng the people.
[2]. the Liu Jingquan of Shanghai Communications University, the people such as Mei Jiabing in " a kind of duodenal sleeve and preparation method thereof " patent of applying for 2012.5.10 day, the patent No.: 201210145497.Thereby above two kinds of technology are all to adopt the polymer sleeve pipe to insert duodenum to allow the food that enters gastric not contact duodenal wall directly to arrive jejunum and reach the MO effect for the treatment of.
Although second method is that sleeve outer wall is improved,, above two kinds of technology still have the some shortcomings part.As: in above two kinds of prior aries: be 1, all that to treat morbid obesity be purpose.2, the polymer sleeve pipe that adopts is all again the tube of the same length, does not meet the needs of individuation state of an illness treatment.
Only improved cover outer tube layer and intestinal wall adhesion in the second prior art, do not paid close attention between internal surface of sleeve pipe and inwall contingent adhesion and reverse so that cause ileac severe complication.Do not design and illustrate for the vital part-anchor portion of sleeve pipe.
After proximal small bowel was bypassed, thing followed intestinal Hormone change can appear.This theoretical foundation is a non-obese diabetes rat experiment, and its result shows, bypass proximal small bowel and do not change diet and body weight can directly be improved diabetes, and the fluctuation of intestinal hormonal readiness can obviously be detected.
Unabsorbed food arrives ileum in advance, excited negative feedback mechanism, i.e. so-called " ileum lock " effect, caused neural and the endocrine mechanism activation, the intestinal hormone discharges, thereby has increased the sensitivity of tissue to insulin, has amplified insulin function, thereby both improved blood glucose, again can loss of weight.
Make the chyme that concentrates be sent to distal small bowel, thereby cause food absorption to reduce and gastric emptying, and can promote to lose weight the secretion of ileum GLP-1 (glucagon-like peptide _ 1) and PYY (gut hormone peptide), thereby reach the purpose of controlling blood glucose.
Obesity companion type 2 diabetes mellitus is accepted the loss of weight operative treatment has become common recognition.But, for Normal-weight or overweight patient with type 2 diabetes mellitus, can carry out operative treatment, therapeutic effect is how, still has dispute.
In the selection of non-obesity diabetics modus operandi, at present also without desirable art formula.Someone uses the not high or slightly higher diabetics of sleeve shape stomach excision+jejunum transposition operative treatment BMI (Body Mass Index), result shows, there is patient's blood glucose of 86.9% to obtain control, and preserved the integrity of intestinal, reduced the complication of nutrition aspect, but anastomotic stoma is more, and the postoperative complication incidence rate is higher.
About opportunity of operation, the research discovery, patient's sick time is longer, and the age is larger, and the probability of recovery from illness is less, so surgical intervention early is quite important to curing diabetes.
Summary of the invention
In view of this, the present invention proposes a kind of duodenal sleeve of not only having worshipped operative treatment diabetes principle and mechanism but also being different from prior art middle sleeve structure.The invention provides a kind ofly can also provide simultaneously at the sleeve pipe that medical field is treated diabetes a kind of and can not only solve prior art middle sleeve outer wall and intestinal wall adhesion and can solve again the problem that mutual adhesion between inwall and inwall causes distortion to cause blocking can also simulate well the technology of human body intestinal canal function after implanting.
The technical solution used in the present invention is in order to achieve the above object:
Insert the duodenal sleeve that is used for the treatment of diabetes under scope, comprise that have on the tube wall of the sleeve pipe that anchor portion that two nitinol rings arranged side by side and the sleeve pipe continuity section of expanding form and two ends communicate can filling liquid or the pipeline of gas, two nitinol rings are arranged on anchor portion triangular tooth structure, and the oral area that the nitinol ring makes sleeve pipe continue the section of expanding struts.
Described pipeline is linear type or helical form.
Described linear type or helical form are at least one end ring shapes in two ends.
The far-end sealing of pipeline, the other end is provided with check valve, and check valve is circumscribed with ascending pipe,
The end that sleeve pipe continues the section of expanding is provided with dentation.
Sleeve pipe continuity is expanded the edge of dentation of end of section and is provided with the rope band of being made by polymer filament.
On two corresponding sidewalls of helical form sleeve pipe, a radiopaque strip is arranged respectively.
The diameter of titanium-nickel wire ring is 5-6cm, titanium-nickel wire diameter 0.008-012cm, two ring spacing 0.5cm.
The serpentine pipe diameter 0.2-0.3cm of spiral pipe, tube pitch is from 1.5-3cm.
Beneficial effect of the present invention: material of the present invention is that Nitinol and biocompatible polymer are that material can well directly use related equipment just can implant to treat type 2 diabetes mellitus under scope.If, can in time take out under scope again when unnecessary, do not need operation.
