Abstract
The utility model relates to a substitute of an oesophagus for clinical medicine, especially an artificial oesophagus. The artificial oesophagus is formed into a tubular structure. A tubular body is made of a metal net and high molecular compounds which are attached on the metal net. The diameters of an upper tube opening and a lower tube opening are increased, wherein, the high molecular compounds pellosils, true silks, and terylene pieces which are attached at the outer side of the metal net. The transplant of the artificial oesophagus causes operation wounds to be reduced by 70%, operation time to be shortened by 50%, operation methods to be simple. The operation can be carried out in a chest cavity, and abdominal incision can not be needed. The healing is fast after the operation, and complication is reduced.
Description
This utility model artificial esophagus relates to a kind of esophagus substitute products that use on the clinical medicine.
The diseased region of excision esophagus must have other organ pipes to be substituted in the esophageal carcinoma operation, to keep gastral seriality, guarantees that food can enter gastro-intestinal digestion by esophagus and absorb.Usually the internal organs that substitute esophagus are stomach or small intestinal, colon etc.Stomach, the former intraperitoneal that is positioned at of intestinal, substituting its operation of esophagus when these organs are shifted in the thoracic cavity is more complicated.Because the time of free stomach or intestinal surpasses the excision required time of esophagus pathological changes, stomach or intestinal be connected with esophagus often needs several anastomotic stoma.Therefore, not only operating time is long, and formality is loaded down with trivial details, and postoperative also brought many complication, except fistula of operative incision, anastomotic stricture, also has that reflux esophagitis, gastric retention, pyloric obstruction, gastrointestinal reverse, gastrointestinal blood is for bad, gastric-intestinal perforation, diarrhoea etc.In fact, stomach or intestinal enter the thoracic cavity and also cause symptoms such as the patient is uncomfortable in chest, out of breath, run counter to physiological function, hinder gastrointestinal emptying and digest and assimilate; The countries in the world medical experts are for after excising pathological changes esophagus section over 90 years in operation on esophagus, do not use Intraabdominal stomach, intestinal and the well-designed body of using, people's tissue as: fascia lata, muscle lobe, pericardium, pleura, trachea, blood vessel wait and replace esophagus.But experimental result is very undesirable, also has many physicians to adopt artificial material in nearly 50 years, as: nylon, polyethylene, silica gel, politef, terylene, carbon element, real silk wait and constitute tubulose product replacement esophagus, but all fail in experiment.Yet various countries physician effort did not in this respect stop.Think that through research for many years present countries in the world scholar exists a problem in artificial esophagus research: i.e. attempt makes the esophagus and the direct end to-end anastomosis of artificial esophagus of body.In fact, in present surgical operation, exist a certain proportion of identical fistula in esophagus and the gastrointestinal end to-end anastomosis and rhynchostome narrow, wherein the fistula incidence rate is 5-15%, narrow incidence rate is 10-30%, since the end to-end anastomosis between the body tissue organ own also exists certain rhynchostome fistula and narrow complication, make the artificial esophagus of body esophagus and non-body carry out effectively coincideing also to be difficulty very, but the quantity of finding the rhynchostome fistula in using the operation on esophagus case of anastomat obviously reduces, illustrate anastomotic stoma as if with mechanical anastomosis its to force bonded effect be good than general manual suture.In surgical operation, also realize to turn in one deck everting suture ratio and coincide by force.In the practice that artificial cardia is transplanted, more realize the firm healing that effectively being sewed with of Esophageal Stent and body esophagus is extremely strong, for these reasons, the utility model proposes a kind of new technical scheme.
The objective of the invention is to: provide a kind of and artificial esophagus body esophagus strong bonded.
The purpose of this utility model can be achieved through the following technical solutions: a kind of artificial esophagus, be tubular structure, it is characterized in that: by making tubular body with macromolecular compound on wire netting and the wire netting, increase, can present bell mouth shape at upper and lower mouth of pipe place diameter.Wherein, described macromolecular compound is to have pellosil, outer attached real silk and polyester flake on wire netting.Utility model does not adopt body tissue, draws materials conveniently, and wire netting can adopt the metal material that comprises memorial alloy, and intensity height, flexible is used the real silk tissue with good biocompatibility simultaneously, is beneficial to and being connected of body esophagus.The appended pellosil of wire netting can adopt films or spraying coating process is made, and the horn mouth of its artificial esophagus stretches in the body esophagus, helps and the body strong bonded.Intermediate phase should have individual bulging body, prevents that artificial esophagus from coming off, gliding.Utilize this utility model and the socket of body esophagus to sew up, both sewed up also and used " U " shape firmly to sew up, body esophagus and artificial esophagus are closely linked with pocket.Artificial esophagus is different with general traditional method with the connection of body esophagus, generally be to be interrupted invering suture with the opposite end, easily fistula, difficult healing, and meet sb. at the airport body esophagus and sew up of the outer cover of this utility model artificial esophagus, Digestive system, food in the esophageal lumen are not contacted with suture, avoided the generation and the junction disunion of fistula.The length of artificial esophagus can be selected according to excision esophagus length, artificial esophagus substitute not only make behind stomach, the intestinal operation simplify, easily and fast, wound is little, and combine more firm with the esophagus junction, postoperative does not have stomach, intestinal juice and is detained, and can prevent to backflow, do not have complication such as pyloric obstruction, no gastrointestinal reverse, depletion of blood confession problem, no gastric-intestinal perforation if install " artificial cardia " additional.
On the technique scheme basis, be to guarantee the strong bonded of artificial esophagus and body esophagus, artificial esophagus is than the bore in human body esophagus or the gastral cavity greatly more than at least 2 millimeters.
Upper and lower pipe end in artificial esophagus embeds esophagus or gastral cavity is funnel-form at intracavity, and with the chamber outward manually the straight length of esophagus be dumbbell shaped.The upper and lower nozzle diameter of artificial esophagus is than the big 2-4 millimeter of human body esophagus internal diameter.
Superiority of the present utility model is: the transplanting of artificial esophagus, can exempt the free of stomach, intestinal and be displaced to and substitute esophagus in the thoracic cavity, operation wound is greatly reduced, reduce 70% approximately, operating time has shortened 50%, and operation method is more simple, can only in the thoracic cavity, carry out, and needn't make abdominal incision, the postoperative healing is fast, and has reduced complication.
Describe in detail below by accompanying drawing and example.
Accompanying drawing: this utility model structural representation.
Embodiment: as figure, a kind of artificial esophagus of this utility model is tubular structure, it is characterized in that: constitutes tubular body 1 by wire netting, on wire netting, has pellosil 12, and outer attached real silk and polyester flake 13,14,15 places present bell mouth shape at the upper and lower mouth of pipe.The tubular body 1 of artificial esophagus is bigger several millimeters than the bore in human body esophagus or the gastral cavity, at least 2 millimeters, the upper and lower mouth of pipe 14,15 diameters are than the big 2-4 millimeter of human body esophagus internal diameter, the upper and lower pipe end that artificial esophagus embeds in esophagus or the gastral cavity is funnel-form at intracavity, and with the chamber outward manually the straight length of esophagus be dumbbell shaped.Use this utility model to make that operation is easy, wound is little, operating time is short, recovery is fast, complication is few, and medical expense can greatly reduce.
