Abstract
The invention relates to a human orificial pipe substitute with baffle edge. Wherein, it is formed by support tube, connector, flexible film and baffle edge; the flexible film is adhered on the support tube; the baffle edge is connected to the end of support tube; the connector is fixed on the support tube. The inventive support tube can effectively avoid around organism to contract to be neck; the connector can effectively reduce the creep of normal orificial pipe to avoid affecting the anastomotic stoma, to obtain firm connection; and the baffle edge can effectively disperse the stress at the anastomotic stoma, to avoid narrow anastomotic stoma. The invention can be made into artificial gullet or trachea.
Description
Technical field
The present invention relates to the succedaneum of a kind of artificial human body intracavity duct, particularly esophagus or trachea, i.e. artificial esophagus or artificial trachea.
Background technology
In the prior art, in the time need excising esophagus because of tumor, usually adopt to promote stomach or intestinal tube and rebuild gastral way with the esophagus proximal anastomosis and solve, this method damage and is non-physiology passage of food greatly, has much to be difficult to the complication that overcomes; And the trachea pathological changes presses for ideal tracheal reconstruction succedaneum need excise the above trachea of 3cm the time clinically.
The inventor is at Chinese patent ZL01107515.5 (patent name: disclose a kind of succedaneum that the human body lumen is rebuild that is used for artificial intracavity duct), the succedaneum when esophagus or tracheal reconstruction particularly, its primary structure is: be made up of tubular body and connector that the memorial alloy intelligent element is made, connector is fixed on the two ends or the end of tubular body, and pellosil partially or completely covers the tubular body of being made by the memorial alloy intelligent element.Product according to this patented technology conceptual design manufacturing, in zoopery and clinical trial, obtained effect preferably, efficiently solve fistula of operative incision, take off technical barriers such as pipe, but, because artificial intracavity duct directly is connected with the tissue of the human body lumen broken ends of fractured bone, because the existence of the bearing stress of mouth of pipe memorial alloy intelligent element, the wriggling of the human body lumen broken ends of fractured bone may cause near the hamartoplasia the connector, as granulation hyperplasia, especially appear among the patient of cicatrix body constitution, thereby the anastomotic stoma that makes artificial intracavity duct and human body becomes narrow, clinical practice is found, the situation of this anastomotic stricture has certain incidence rate, still can't effectively be solved at present.Therefore, above-mentioned patented product still needs further to improve and is perfect, to reduce the incidence rate of the artificial intracavity duct anastomotic stricture in the part patient.
Summary of the invention
The object of the present invention is to provide a kind of artificial human body intracavity duct with buffer edge, the succedaneum of human body esophageal reconstruction or tracheal reconstruction particularly, it can solve human body esophagus or trachea excision back esophagus or tracheal reconstruction problem, the problem that can efficiently solve fistula of operative incision, take off pipe, particularly anastomotic stricture effectively.
The object of the present invention is achieved like this:
The artificial human body intracavity duct of band buffer edge of the present invention is made up of stay pipe, connector, flexible material film and buffer edge; Described flexible material film is attached on the stay pipe; Buffer edge is connected the end of stay pipe; Connector is fixed on the stay pipe, apart from the end 1mm～30mm of stay pipe.
Described buffer edge is the film that flexible material film is extended beyond the end of described stay pipe, and the thickness of buffer edge is more than or equal to the thickness of flexible material film, and the length of buffer edge is between 1mm～30mm.
In addition, described buffer edge can also be the film that flexible material film is extended beyond the end of described stay pipe, and this film forms crimping to the upset of the outside, described stay pipe end, constitutes crimping type buffer edge.
Described stay pipe is the cancellated body of being made by the elastomeric material that can recover or recover substantially the preceding shape of distortion after being out of shape and being out of shape again.
Further, described stay pipe is the network structure body that medical metal material silk or fibrage become; Or the network structure body of the helical spring of medical metal material spun gold coiled composition; Or the crooked resilient medical metal material thin-walled network structure body of energy through forming after the digital control processing; Or through the crooked resilient medical metal material thin-walled network structure body of energy behind the laser engraving.
Particularly, described medical metal material is selected from: Metal Substrate medical materials such as medical titanium alloy (as: Ti-Ni marmem, beta-titanium alloy), medical stainless steel, medical zircaloy.
Described stay pipe can have different geometries, as: cylinder tube shape, the single bell-mouthed cylinder tube shape of band, the two single bell-mouthed cylinder tube shapes of band etc.
Described connector is the circulus with the medical flexible material manufacture.
Further, described connector is with medical flexible material silk or fiber, by the circulus of braiding or knitting manufacturing.
Described flexible material film is can be at the thin film of the medium-term and long-term medical flexible material manufacture of implanting of human body.
Further, described medical flexible material is can be at the medium-term and long-term medical flexible material of implanting of human body, materials such as terylene (dacron fibre), polyethylene, polyurethane, politef, silica gel, polypropylene, Merlon, polyether-ether-ketone, polysulfones, ionomer, styrene-butadiene polymer, polyamide, poly-polypeptide, polymethyl methacrylate, polyethers polyamide block copolymer.
Described connector passes through the operation suture thread sutured on stay pipe.
Anti-recirculation device is installed in the described stay pipe, and anti-recirculation device is installed in the far-end of stay pipe usually.The artificial human body intracavity duct of the anti-recirculation device of the present invention's band adopts when carrying out esophageal reconstruction usually after the esophagus excision.
Further, described anti-recirculation device is petal-shaped structure, has usually: specific designs such as 2 lobe formula structures, 3 lobe formula structures, 4 lobe formula structures, 5 lobe formula structures, 6 lobe formula structures.
In addition, described anti-recirculation device can also be an oversleeve type check valve-type structure.
Because the present invention has adopted the body of main body for the stay pipe formation of band film, at place, end connector has been installed near body, be used for sewing up with human body lumen (as esophagus, the trachea etc.) broken ends of fractured bone that keeps, the wriggling of human body lumen (as esophagus, the trachea etc.) broken ends of fractured bone that slows down reservation is to the influence of anastomotic stoma, and the end edge of the body that forms at the stay pipe of band film manufactured and designed buffer edge, further reduced the stress concentration that stay pipe forms at the anastomotic stoma place.Adopt this pipe structure, can prevent effectively that cambium shrinks form narrow on every side; Connector can effectively slow down the influence of normal human's lumen (as esophagus, trachea etc.) broken ends of fractured bone wriggling of reservation to anastomotic stoma, sets up in succession firmly, prevents fistula of operative incision and takes off pipe; The stress concentration that buffer edge can effectively disperse stay pipe to form at the anastomotic stoma place reduces or avoids the appearance of human body lumen (as esophagus, trachea etc.) anastomotic stricture situation.
