Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of single riveting, self-adaptation type oval hole plugging device.
Background technology
Oval foramen occurs in the development of fetus phase, and blood must flow to the left side by this breach on the right of heart.It is most of
In the case of general the 1st year self-closed after life of oval foramen, if child's oval foramen more than 3 years old does not close title acleistocardia still
(Patent foramen oval,PFO).There is 20%~25% oval foramen not completely closed in adult.Acleistocardia is
Most commonly seen congenital cardiac anomaly in adult at present, in normal population can detect 1 people in about 4 people suffers from this disease.I
The patients with congenital heart diseases of state 1,500,000, annual congenital heart disease illness rate is 6.78%, and annual new born children with CHD is up to 100,000-15 ten thousand
Example, wherein simple acleistocardia accounts for the 10% of congenital heart disease.
The problem of acleistocardia is a kind of very common, and PFO holes are also possible that causes potential severe complication.
For a long time it is believed that acleistocardia does not cause the shunting in two rooms typically, influence is had no on the haemodynamics of heart,
It is thus regarded that " unimportant ".In recent years many studies have shown that, deposited between acleistocardia and unknown cause patients with cerebral apoplexy
In close contact, because by the oval foramen of patent, following embolus can feel concerned about system into a left side and cause corresponding clinic
Symptom：1st, the thrombus of deep veins of lower limb or pelvic veins；2nd, bends or the air embolus caused by decompression sickness；3rd, operation or wound
The fat embolus formed afterwards.And for occurred the acleistocardia patient of Cardioversion its it is recurrent it is dangerous still very
It is high.In addition, it has been found that acleistocardia is relevant with the morbidity of decompression sickness, antimigraine etc., closure oval foramen may be beneficial to above-mentioned
Patient.
Current main product is that the holy tradition still up to medical supplies company, Beijing Starway Medical Technology Inc.'s production is double
The double riveting PFO plugging devices of disk and innovative product -- the one-sided metallic coating PFO plugging devices of Shenzhen lifetech Scientific Inc., are facing
The problem of all having more or less in bed use.
1. waist diameter design is fixed (4-6mm), but oval foramen " hole " diameter of patient varies with each individual, with fixation
The PFO plugging devices of size can not be blocked completely.
2. plugging device is designed as double plate or class double plate structure, disk distance between the surface is fixed, have during clinical practice laminating it is not tight,
Come off equivalent risk, and plugging effect is not good, and immediate postoperative residual shunt is more serious.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of single riveting, self-adaptation type oval hole plugging device.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of single riveting oval hole plugging device, main body is
Metallic support Dropbox with default self-expanding function, the metallic support Dropbox includes a plurality of interlaced and along described
The braided wires of body winding, the end face of the main body is provided with left card, and other end is provided with right card, the left card and described
Right card is parallel, is provided between the left card and the right card in waist, the waist and is enclosed with the first filler, described
Provided with a metal die to collect the metal twine of the metallic support Dropbox on the outside of the center of right card, the elastic device is welded
It is connected in the metallic support Dropbox of the waist, and connects the left card and the right card, the left card and institute respectively
The cross section for stating right card is equipped with the second filler.
The present invention can make card laminating close using the design of double plate button type, difficult for drop-off；Single head is designed without riveting, easily
Climb attached in endothelial cell, the endothelialization time is reduced, while thrombosis can be reduced；Realize the adaptive of waist structure, root
According to oval foramen " hole " diameter of patient, waist is expanded to automatically to be blocked completely with its diameter formed objects, composition, simultaneously
Automatic to adapt to card spacing, further solution laminating is not tight, come off equivalent risk, and immediate postoperative ultrasonic examination residual shunting is dropped significantly
Low, plugging effect is dramatically increased.
Further, the braided wires are Nitinol.
Using the beneficial effect of further technology：Nitinol is a kind of marmem, and marmem is energy
The plastic deformation of itself is automatically restored to the special alloy of original-shape under a certain specified temp.Its expansion and contraction is 20%
More than, fatigue life is extremely long, and damping characteristic is higher than common spring 10 times, and its corrosion resistance is medical stainless better than best at present
Steel, therefore can meet the application demand of all kinds of engineerings and medical science, is a kind of very outstanding functional material.
Further, first filler is polyester fiber non-woven fabric and polyurethane nucleome, the polyester fiber non-woven fabric
The polyurethane nucleome is wrapped up, second filler is polyester fiber film.
Using the beneficial effect of further technical scheme：Different functions are realized using the filler of two kinds of different materials,
Very well, with higher intensity and elastic recovery capability, and polyurethane nucleome has the wrinkle resistance and conformality of the polyester fiber
There is good radiopacit, be easy to lay and position during operation.
Further, the volume of the polyurethane nucleome is not less than 1/3rd of the waist.
Using the beneficial effect of further technical scheme：The compact structure of the polyurethane nucleome, is being used as developing mark
While play a part of support plugging device.
Further, the elastic device includes many interlaced the first springs and second wound along the body central
Spring, the two ends of first spring are respectively welded in the left card and the right card, first spring it is flexible
Direction is vertical with the plane where the left card and the right card, and the second spring winding is arranged on first bullet
On spring, the telescopic direction of the second spring is vertical with first spring.
Using the beneficial effect of further technical scheme：First spring is determined between the left card of the plugging device and right card
Away from, prevent plugging device from coming off, second spring determine waist thickness, completely closure patient oval foramen " hole ".
Further, first spring is extended state, and the second spring is compressive state.
Using the beneficial effect of further technical scheme：The meeting self-constriction of first spring, is limited between left card and right card
Away from, prevent plugging device from coming off, second spring can self-expanding, completely closure patient oval foramen " hole ".
