Description
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%).Within 2025, will reach 2-3 hundred million people.The operative treatment domestic, 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.
In to the retrieval of prior art, find:
[1] .KeithS.Gersin, MD, JenniferE.Keller, MD, Dimitrios Stefanidis, Deng people 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 morbid obesity endoscopic assistance completely for one).
[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 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 some shortcomings part.As: in above two kinds of prior aries: be 1, all that to treat morbid obesity be object.2, the polymer sleeve pipe adopting is all again the tube of the same length, does not meet the needs of individuation state of an illness treatment.
In the second prior art, only improve between cover outer tube layer and intestinal wall and adhered to, do not paid close attention to contingent adhesion between internal surface of sleeve pipe and inwall 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 is bypassed, there will be thing followed intestinal Hormone change.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, excite negative feedback mechanism, i.e. so-called " ileum lock " effect, cause neural and endocrine mechanism activation, 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 concentrating 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 object of controlling blood glucose.
Obesity companion type 2 diabetes mellitus is accepted loss of weight operative treatment has become common recognition.But, for Normal-weight or the 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 applies 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 preserve the integrity of intestinal, reduce the complication of nutrition aspect, but anastomotic stoma is more, postoperative complication incidence rate is higher.
About opportunity of operation, research finds, patient's sick time is longer, and the age is larger, and the probability of recovery from illness is less, and therefore surgical intervention is early 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 of sleeve pipe that can treat diabetes at medical field a kind of technology that can not only solve prior art middle sleeve outer wall and intestinal wall adhesion and can solve again problem that mutual adhesion between inwall and inwall causes distortion to cause blocking and can also simulate well human body intestinal canal function after implanting is also provided simultaneously.
In order to achieve the above object, the technical solution used in the present invention is:
Under scope, insert the duodenal sleeve that is used for the treatment of diabetes, comprise that two nitinol rings arranged side by side and sleeve pipe continuity expand that have on the anchor portion of portion's composition and the tube wall of the sleeve pipe that two ends communicate can filling liquid or the pipeline of gas, two nitinol rings are arranged in anchor portion triangular tooth structure, and the oral area that nitinol ring makes sleeve pipe continue the portion 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 portion of expanding is provided with dentation.
The edge that sleeve pipe continues the dentation of the end of the portion of expanding is provided with the rope band of being made up of polymer filament.
On two corresponding sidewalls of helical form sleeve pipe, respectively there is a radiopaque strip.
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, when unnecessary, can under scope, take out in time again, do not need operation.
