Abstract
An antislip occluder for interatrial and ventricular septal defects comprises an elastic net and sealing membranes. Nickel-titanium alloy wires are woven, are molded and then are subjected to heat treatment to form the elastic net, the elastic net comprises a middle cylindrical concave waist, a hollow left disc and a hollow right disc, the left disc and the right disc are respectively connected with the left end and the right end of the concave waist, a sealing head capable of fixedly tucking heads of the alloy wires is welded in the outer center of the left side of the left disc, a connector capable of fixedly tucking the heads of the alloy wires is welded in the outer center of the right side of the right disc, a threaded hole is arranged in the middle of the connector, the two polyester sealing membranes are respectively adhered on the inner wall of the inner right side of the left disc and the inner wall of the inner left side of the right disc, and two annular bosses are coaxially arranged on an annular plane of the right side of the left disc. The antislip occluder has the advantages that the occluder can be effectively stopped from slipping on a septal wall after surgery on the basis that internal elastic stress on the occluder is not increased, and secondary blood leakage at the septal wall due to slipping of the occluder after the surgery can be prevented.
Description
Technical field
The present invention relates to a kind of medical stopper, the particularly anti-skidding stopper of a kind of atrial ventricle's septal defect, it is mainly used in repairing in the intervene operation the damaged of congenital atrium, ventricular septum.
Background technology
Congenital heart disease atrial septal defect and ventricular septal defect all are common congenital heart diseases, are particularly big killers of children's health of harm humans health, this disease in China's year morbidity amount more than 100,000 people.The characteristics of its pathological changes of heart atrial septal defect are that the spacer film between the left atrium is failed normally closed, and blood flows between left atrium and right atrium; The characteristics of its pathological changes of ventricular septal defect are that normally closed is failed at the interval between the left and right ventricles, and blood is flowed between left ventricle and right ventricle.Because the pressure of left atrium is higher than right atrium, so the part blood of left atrium flows to right atrium through atrial septal defect punishment.Because the leakage of blood, the burden that causes the right side to feel concerned about system increases, and causes right ventricular hypertrophy, pulmonary hypertension, arrhythmia and heart failure.When causing blood leakage, the heart septal defect more just need repair the septal defect place.Two kinds of diseases of therapist all adopted operating method in the past, and this method wound is big, patient is painful, the post-operative recovery phase is long.In recent years, along with the development of heart intervene operation, Wicresoft interventional therapy atrium, interventricular septal defect have become main developing direction.
At present existing multiple heart is used to treat congenital cardiac septal defect every damaged stopper, the main part of stopper is a metallic elastic net that has the default profile of memory and can be shrunk to strip mostly, be provided with the diaphragm seal that one deck intercepts blood flow in the elastic network(s), after stopper is opened, return and to recover its default profile, becoming a centre is cylindrical eel-like figure, and respectively there is the I-shaped structure of a disk at the eel-like figure two ends.Utilizing the advantage of stopper treatment heart septal defect is that otch is little, only in femoral artery, the puncture of femoral vein place, under the supervision of X-ray and color ultrasound, stopper is implanted the defect of ventricle or atrial septum through conduit, determine slowly to open stopper after the defect, the eel-like figure of stopper is placed on original damaged place, damaged spaced walls is clamped by left and right two disks of stopper, make damaged closure, reach the purpose of clinical cure.But owing to select side seal to block up the inappropriate problem of device model before the problem of stopper self structure and the art, operation the situation that the stopper slide displacement produces blood leakage again occurs by regular meeting.Analyze its reason and be roughly two aspects, the one, the elasticity of stopper self is stepped up the power deficiency, fails self to be clamped in firmly on the damaged spaced walls, when heart is constantly shrinking and during extensional motion, stopper is extruded the generation slide displacement; The 2nd, the problem of stopper structure, the card of two disks of the responsible damaged spaced walls of clamping is too level and smooth, is easy to generate slide displacement.But, we know if the clamping force of two disks is too big on the stopper, must influence the blood circulation of spaced walls part, make this place's tissue downright bad because of ischemia, overcome the only way that it easily produces slip so only improve to be only in the structure of stopper.
Summary of the invention
The objective of the invention is to remedy defective and the deficiency of prior art, provide a kind of atrial ventricle septal defect anti-skidding stopper, it can be clamped on the spaced walls of heart defect firmly with less clamping force, is difficult for producing leaking, and has good bio-compatibility.
For achieving the above object, the technical solution used in the present invention is as follows: the anti-skidding stopper of a kind of atrial ventricle septal defect, comprise elastic network(s), diaphragm seal, end socket, joint, wherein elastic network(s) is to form by mould compression moulding and heat treatment with the nitinol alloy wire braiding, the alloy silk that constitutes elastic network(s) is interlaced, hollow shape left side disk and right disk that cylindric recessed waist that elastic network(s) comprises its middle part and two ends, the recessed waist left and right sides are being connected respectively, the diameter of a left side disk and right disk is greater than 5～20 millimeters of the diameters of recessed waist, its profile of whole elastic network(s) is I shape, the silk head that constitutes several alloy silks of elastic network(s) collects in the center of left disk left surface and right disk right flank respectively, disk left hand external center, a left side is welded with a silk head with the alloy silk and draws fixing end socket in, right disk right hand external center is welded with a silk head with the alloy silk and draws fixing joint in, the joint middle part has one for the screw of the seal wire that spins, above-mentioned end socket and joint are made by Nitinol, respectively be bonded with one deck polyester diaphragm seal on the left disk inner right side inwall He on the right disk inside left inwall, the coaxial twice annular boss that is provided with on the planar annular of the right side of left disk, the spacing of twice annular boss is 4～7 millimeters, and the cross section of annular boss is circular arc, triangle, trapezoidal.
The written or printed documents stopper has good shape memory function, and when axial tractive end socket and joint, the stopper deformable is strip, can restore to the original state immediately after external force is removed.
The present invention compared with prior art beneficial effect is: plugging effect is good, on the basis that does not increase stopper inner elastomeric stress, the twice annular boss can effectively stop the stopper postoperative to slide in spaced walls, can avoid postoperative to produce spaced walls place blood leakage again because stopper slides.
