Abstract
The present invention relates to a gastrointestinal support and a manufacture process thereof. The support is a reticular tube and is made into the form of a revolving body rotated around a central shaft, wherein the maximum diameter of the head end of the support is from 30% to 140% of the diameter of a middle main body reticular tube, and the head end is in a circular arc shape; the inner diameter of end edge of the tail end of the support is identical to the diameter of the tail end or slightly greater than the diameter of the middle main body reticular tube, and the end edge is in a ball shape or mushroom shape; the diameter of the middle main body reticular tube is from 18 to 28mm; an included angle alpha which is greater than 90 degrees and less than 120 degrees is formed between a shoulder and the middle main body reticular tube, wherein the transverse upward length of shoulder is 5mm, and cambered metal wires are arranged at the end edges of the head and the end of the support. The gastrointestinal support has the advantages of reasonable structure, convenient manufacture and use, convenient industrial production, low cost and favorable effect.
Description
Technical field
What the present invention relates to is that a kind of gastrointestinal stenosis that causes because of tumor or other reason that is used for the treatment of blocks or the gastrointestinal tract support of seepage and other processing technology.
Background technology
Existing like product structure is generally basin shape double horn net type (as Fig. 4), basin shape double horn " Z " shape (as Fig. 5), single speaker net type (as Fig. 4) of basin shape and the straight webmaster cutting of no loudspeaker type (as Fig. 6).
Its defective: the afterbody horn mouth ora terminalis of basin shape abduction or straight afterbody ora terminalis (Fig. 5) crimping esophageal wall, gastrointestinal wall form sharp property otch, are subject to enterokinesia, swallow wriggling or heartbeat influence and intestinal wall, esophageal wall are stimulated cause neointimal hyperplasia and pain.Tail end abduction basin shape (Fig. 5) then can produce intussusception to the far-end gastrointestinal tract and cause and have an intense pain when support pass is glided by wriggling.Mild wedge shape shoulder (Fig. 4, Fig. 5) and straight nothing shoulder webmaster (Fig. 6) are difficult for being played by the narrow section incarceration effect of support fixation support, so easily produce sliding transfer.Rack edge tinsel opisthotonos acute angle (Fig. 4) or " Z " wedge angle (Fig. 5) and cut end prickle (Fig. 6) easily puncture tube wall and cause the hemorrhage even tube chamber perforation of pain, and the head ora terminalis of basin shape abduction (Fig. 4, Fig. 5) or loose prickle shape (Fig. 6) is difficult for lifting adjusts or reclaim support.Their processing technology is to make mould in advance with the product structure shape, just finishes braiding on this mould, the big cost height of its difficulty, and braiding speed is slow, and quality can not guarantee again.
Summary of the invention
The objective of the invention is to the defective at above-mentioned existence, it is good to propose a kind of structure suitability, and processing technology is convenient, cost is low, braiding speed is fast, the gastrointestinal tract support of quality assurance and other processing technology.
Technical solution of the present invention:
The Weaving type gastrointestinal tract support, it is characterized in that it is a webmaster, be around axis rotate rotational-like, the maximum gauge of its cephalic par is the 130%-140% of intermediate host webmaster diameter, its tail end ora terminalis internal diameter is slightly larger than the diameter of intermediate host webmaster, cephalic par and tail end are two bulb shapes of interior receipts, the diameter 18-28mm of intermediate host webmaster, an angle α is arranged between shoulder and intermediate host webmaster, 120 °＞α＞90 °, shoulder length 5mm transversely, the ora terminalis tinsel of head, tail end is curved, its angle is less than 180 degree, greater than 90 degree.
The processing technology of Weaving type gastrointestinal tract support, its step: (one) divides three sections with the straight-bar mould, cephalic par, intermediate host webmaster, tail end, the helical pitch V1 of their correspondences, V, V2 have nothing in common with each other, the diameter D of mould is identical, N spiral the end of a thread number arranged, N braiding promptly is installed on head, tail end hangs the silk nail; (2) the braided support blank on the straight-bar mould with titanium-nickel wire or stainless steel silk, blank is straight circular cylinder type, has woven the back and has deviate from from this mould; (3) make shaper according to gastrointestinal tract support, the support blank is enclosed within and heat-treats typing on the shaper, and the titanium-nickel wire temperature control is at the 450-520 degree, and the stainless steel silk temperature control is about 380 degree, and the temperature control time is about 40 minutes; (4) put into quenching-in water, take off from shaper then;
Advantage of the present invention:
Rim of a cup ball tail shape support (Fig. 3) is applicable to narrow esophagus.The head support that rim of a cup shape is expanded, be attached at pathological changes near-end normal esophageal wall, play the effect of stable and shutoff fistula mouth (special membrane support).The ora terminalis of receiving in its head is fitted with nearly section esophagus, can reduce the stimulation to esophageal wall, and makes and lift that to adjust or reclaim support safer, convenient.The shoulder (becoming the angle) that the intersegmental diameter sudden change of the head section of expanding and main body webmaster forms less than 120 ° but incarceration in narrow section near-end fornices, play center rest, stop the effect of downslide.The afterbody that spherical (or mushroom-shaped) expands plays the supporting role (be used for pars cardiaca and stop upwards sliding transfer) of center rest, its interior receipts circular arc is connected with far-end normal esophageal wall appropriateness can comply with esophageal peristalsis, avoids damaging esophageal wall and intussusception esophagus (be used for pars cardiaca and then avoid damaging coat of the stomach).Turn back head, the end edge of braiding of arc can reduce damage to normal esophageal wall and be difficult for puncturing tube wall and cause that pain, hemorrhage and tube chamber bore a hole.Two bulb-type supports (Fig. 1) are applicable to the following enteric cavity of the duodenum section of falling, its head that expands, afterbody can support intestinal wall, play the effect of center rest, interior receipts circular arc is complied with tortuous enteric cavity and is connected the stimulation that can reduce intestinal wall, avoids bleeding due to trauma and intussusception or folding to close intestinal tube.Oral, the spherical tail type of basin support (Fig. 2) is applicable to that stomachus pyloricus or gastrointestinal anastomosis are narrow, its abduction shallow pot shape horn mouth and the roomy gastral cavity of narrow section near-end adapt, and the shoulder that support caliber sudden change forms (diameter less than be 120 °) can support and be embedded in the narrow section near-end and play center rest, stop the effect of gliding.
