Compared with prior art, the invention has the advantages that：
（1）Effectively blocking small intestinal of the invention is digested and assimilated to food, closely, is snugly contacted with gastric mucosa, and can be kept
The contractile function of pylorus.
The duodenal stent of the present invention is inserted in harmonization of the stomach duodenum, with reference to Fig. 7, is originated in the pylorus 4 of stomach 100, is covered
The part duodenum section that is connected with pylorus 4 of lid or whole duodenum section 101, be with wine cup shape network and sleeve pipe,
Particularly implement to intercept with sleeve pipe, the digest chyme of gastric when duodenum, only part or completely not with ten
Two duodenum 12 inwalls are contacted, and so as to reducing or even excluding duodenal digestion and Absorption completely, effectively blocking small intestinal is to food
Thing is digested and assimilated, and the absorption of sugared part is reduced from source.
Duodenal stent is in close contact with the gastric mucosa at stomach pylorus so that diabetes involving middle-JIAO compound（Food）It is substantially all and passes through
Support is discharged to duodenum or jejunum.During duodenal stent setting treatment, certain elastic force is produced, duodenal branchess are made
The near-end cup bottom disk of frame closely, is snugly gently pressed on the mucosa of stomach.To realize above-mentioned functions, metal rack is designed to
Goblet shape, cup bottom disk are the near-ends of support（It is so-called proximally and distally, for being relative operator：One device is near operation
One end of person is near-end, is distal end away from the other end of operator）Be placed in gastric, in order that its with gastric mucosa closely, it is docile

Integral formula.
（2）The effect of the duodenal stent preparation method of the present invention and effect are as follows：
According to the winding method coiling of circular metal webmaster of the present invention, two groups of helixes can be formed, one of which be it is left-handed, it is another
For dextrorotation, two groups of helix mutually activities intersect group, constitute many little networks.Exactly, adjacent two left-turn spirals
Line and adjacent two right-hand helixs intersect, and constitute little network unit, and whole circular metal webmaster is completely by this
A little little network units are constituted.The one group of network unit for along the circumferential direction arranging, its summit respectively positioned at three that
On this adjacent circumference, the end that each section of Stent assembling die is also all located at the intersection of this two groups of left-right rotary helixes
On the constituted circumference of point, Fig. 6 is seen.Different helical pitch λ of each section of employing of metal net support, has the disk of proximal segment high
Counter-bending elasticity, stage casing have relatively low radial support power, and distal ports have higher radial support power, thus, distal ports cup
The lead of helix of body is minimum, and the helical pitch of interlude cup shank is maximum, and the helical pitch at proximal segment cup bottom is placed in the middle.
According to the circular metal webmaster of winding method coiling of the present invention, helix does not repeat.
According to the circular metal webmaster of winding method coiling of the present invention, the mutually activity of its two groups of helixes intersects.
When a left-handed or right-hand helix, when intersecting with another group of dextrorotation or left-handed parallel helix, along this
Root is left-handed or right-hand helix on adjacent cross point, this left-handed or right-hand helix is in another group of dextrorotation or left-handed parallel
It is alternate that helix is upper and the next, that is to say, that as this root is left-handed or right-hand helix is in a cross point
When face is by another group of dextrorotation or left-handed parallel helix, then when by next cross point, in another group of dextrorotation or left-handed
Below parallel helix, with reference to Fig. 5.In these cross points, two Ni-Ti shape-memory alloy wires of different trends are only mutual
Intersect, when support deforms, this two silks can produce relative displacement, thus, these cross points are all slip-knot points.Compile
When casting off into, two terminations of this root Ni-Ti shape-memory alloy wires will overlap, and position is typically answered in the position that termination overlaps
In the middle part of support.
After the setting treatment of support, support has the function of memory finished product support shape and size, i.e., when support is in about
When pencil state or compressive state, it has self-expanding ability.
（3）The present invention is had the advantage that for the mould for preparing circular metal webmaster：
Using the combined knitting mould of the segmentation shown in Fig. 6, when the head number of helix is identical, each section die as needed can be with
Different helical pitches are chosen, thus, each section of support for knitting out has different size of network, also just has different mechanics
Performance：Each section of support has different radial support power and different axial bending strengths.
（4）The support inserting device tool of the present invention conveniently, reliably can be realized back after duodenal stent is inserted and finished
Remove.
Raidal drainage hole 88 is machined with the main chamber 84 of core pipe, Fig. 8 is seen, to recall during support inserting device tool, from handle
Liquid injection hole injects distilled water, flows into the gap between rack sleeve and support inserting device tool, when distilled water is injected, while withdraw propping up
Mount into apparatus, side left rotation and right rotation support inserting device tool, in case the sleeve pipe of support is wrapped on support inserting device tool, affect support
Insert apparatus to exit from rack sleeve.
（5）The binding method of duodenal stent of the present invention
Support mode of movement bundlees method for releasing using support, whole duodenal stent is equably enclosed within support first and is inserted
On apparatus, then proximally and distally the bundling duodenal stent with lashing wire, make duodenal stent be fixed on conveying dress
Put.After support inserting device tool is inserted in place together with support, pull support inserting device tool afterbody is lashing wire, you can break rope
Knot, discharges support.Pull lashing wire is broken the principle of knot and sees Figure 15.
When support is installed, by support casing in the core pipe for inserting apparatus, the distal end of rack sleeve is close to the near-end of soft head.
The two ends of duodenal stent during binding, are only bundled, i.e., only bundlees support proximally and distally, at the rack sleeve of remainder
In nonbinding state.The effect of rack far end binding is the position for fixing duodenal stent sleeve pipe on apparatus is inserted, and is prevented
Sleeve pipe occurs to slide on apparatus core pipe is inserted, thus, the number of turns of lashing wire is as few as possible, usual 1 ~ 5 circle；And mount proximal end bundle
The effect tied up, is not only fixed support and the relative position for inserting apparatus, and wire netting pipe holder is snugly bundled,
It is easy to insert apparatus insertion digestive tract.Now, bundle the number of turns more, bundle the table that coil is evenly distributed in wire netting pipe holder
On face.Duodenal stent is bundled in the distal end for inserting apparatus, the lashing wire first support lashing wire 87, Jing of rack far end
By the first support binding line passage 851 in core pipe, from the first support binding linear window of core pipe distal end（82）Pass, by Figure 13
Binding method, the distal end of rack sleeve binding 1 ~ 5 is enclosed, knot breaks order for from the close-by examples to those far off；The binding of mount proximal end
Line second support lashing wire 86, via the second support binding line passage 852 of core pipe, by second support lashing wire in core pipe
Window（83）Pass, the near-end of support is bundled with same binding method, it is ensured that metal base portion is docile to be bundled in
Insert on apparatus, and the order of breaking of knot is then to draw near.The tail end of first and second lashing wire is by the handle tail for inserting apparatus
Pipe is passed, and during release support, first pull second support lashing wire discharges the near-end of support；When mount proximal end metal rack
Part position it is appropriate after, then pull first support lashing wire discharges the distal end of support.This binding method is referred to as two-wire by us
Two ends bundle method, and Figure 13 is seen in position of the duodenal stent on apparatus is inserted.
In order to shorten coated length of the support on support inserting device tool, longer sleeve pipe can be using axial intussusception or axle
Method to folding, is shown in Figure 15 and Figure 16.When sleeve pipe is using axial intussusception or the mode of movement for axially folding, and support
Proximally and distally bundle respectively, equally only binding 1～5 is enclosed for distal end, but the binding number of turns of near-end should be by after axial intussusception or folding
Support tied line to bundle completely, it is ensured that whole duodenal stent is snugly coated on a conveyor, Bu Huiying
Ring the insertion human body alimentary canal of the conveyer device with duodenal stent.It is bundled in after sleeve pipe axial direction intussusception or axially folding again defeated
The mode of movement on device is sent, two-wire axial direction intussusception binding conveying method is referred to as and two-wire is axially folded binding conveying method.This
The binding order and release order of two kinds of binding carrying method supports is identical with two-wire two ends binding method.
The two ends binding of duodenal stent can also be realized with a lashing wire.Now, the core pipe of inserter is using double
Lumen, is shown in Figure 10, and lashing wire 87 is released by the first binding linear window 82 distal end of binding duodenal stent, lashing wire again by
Second binding linear window is extracted out, bundlees the near-end of duodenal stent, and near-end binding finishes rear lashing wire and penetrates the second binding again
Linear window, the secondary chamber 851 of Jing core pipes 8 is passed by the tail pipe 94 of handle.
