Abstract
The utility model relates to the technical field of medical instruments, and discloses a heart defect occluding device. The occluding device comprises a supporting skeleton and an occluding film; the supporting skeleton is a cylinder with an inner cavity, the longitudinal section of the supporting skeleton is I-shaped, the head and the tail of the supporting skeleton are respectively disc-shaped, and the waist of the supporting skeleton is provided with an annular protrusion; and the occluding film is arranged in the supporting skeleton. The supporting skeleton is made of a nickel-titanium alloy material; and the occluding film is made of a polyester fiber material. The waist of the I-shaped supporting skeleton is provided with the annular protrusion, so that the shape of the occluding device can be automatically adjusted according to the heart defect form to adapt to heart defects with different lengths in different shapes, and the occluding device is difficult to drop.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of heart defect stopper.
Background technology
Heart septal defect is a kind of common congenital heart disease, and the mechanism of pathological changes is that normally closed is failed at the interval between left and right ventricles or the atrium.Under normal circumstances, the blood pressure of the left heart is higher than the right heart, if the centre produces the burden increase that damaged meeting causes heart, pulmonary circulatory blood volume increases, and finally can cause pulmonary hypertension, arrhythmia and heart failure.
Chamber/atrial septal defect plugging device is meant the medical apparatus and instruments through conveyer device shutoff chamber/atrial septal defect.Conventional chamber/room lacks and is the double plate type, but darker and when irregular when chamber/atrial septal defect hole, and conventional chamber/room is scarce just to be difficult to reach instructions for use.There is following shortcoming in existing chamber/atrial septal defect plugging device: 1, because heart defect is irregular, the conventional two umbrella shapes of stopper are because it adopts the waist form fixedly to be prone to produce blood residual flow in various degree; If 2 damaged holes are darker, the waist of conventional stopper is because its length is fixed thereby cause clamping length to come off inadequately and easily, thereby is prone to cause thrombosis, when serious even need open chest surgery that this stopper is taken out.
The utility model content
The technical problem that (one) will solve
The technical problem that this utility model will solve is how a kind of difficult drop-off is provided, can adjusts clamping length automatically, is applicable to the heart defect stopper of different length and shape.
(2) technical scheme
For solving the problems of the technologies described above; This utility model provides a kind of heart defect stopper, comprises support frame and shutoff film, and said support frame is the column with internal cavity; The longitudinal section of said support frame is I-shaped; Its head and afterbody are respectively plate-like, and its waist is provided with annular projection, and said shutoff film is arranged on the inside of said support frame.
Wherein, said support frame is formed by many one metal wire braidings, and its head is fixed through first metallic sheath, and its afterbody is fixed through second metallic sheath, and the bottom of said second metallic sheath has screwed hole.
Wherein, said support frame is processed by shape memory alloy material.
Wherein, said support frame is processed by nickel-titanium alloy material.
Wherein, said shutoff film is processed by Polyester Fibers.
Wherein, said first metallic sheath and second metallic sheath are processed by stainless steel material respectively.
Wherein, said shutoff film adopts sewing thread to be sewn on the said support frame.
Wherein, said annular projection is one or more.
(3) beneficial effect
A kind of heart defect stopper that this utility model provides; Waist at I-shaped support frame is provided with annular projection; Make this stopper to adjust himself form automatically according to the heart defect form, being applicable to the heart defect of different length and shape, and difficult drop-off.
Description of drawings
Fig. 1 is the schematic cross-section of a kind of heart defect stopper of this utility model;
Fig. 2 is the schematic cross-section of the another kind of heart defect stopper of this utility model.
Among the figure: 1, support frame; 1-1, annular projection; 2, shutoff film; 3-1, first metallic sheath; 3-2, second metallic sheath.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of this utility model is described in further detail.Following examples are used to explain this utility model, but are not used for limiting the scope of this utility model.
Like Fig. 1 and Fig. 2; A kind of heart defect stopper of this utility model comprises support frame 1 and shutoff film 2, and support frame 1 is for having the column of internal cavity; The longitudinal section of this support frame 1 is I-shaped; Its head and afterbody are respectively plate-like, and its waist is provided with annular projection 1-1, and shutoff film 2 is arranged on the inside of support frame 1.Annular projection 1-1 can be one or more, and the longitudinal section of this annular projection 1-1 is to be made up of two square or trianglees or arc.It among Fig. 1 a schematic cross-section that the longitudinal section is the stopper of quadrate annular projection 1-1; Fig. 2 is the schematic cross-section that to have three longitudinal sections be the stopper of leg-of-mutton annular projection 1-1.
Wherein, support frame 1 can be worked out by many one metal wires, and this tinsel is a shape memory alloy material; Be preferably nickel-titanium alloy material; This support frame 1 head is fixed through the first metallic sheath 3-1, and its afterbody is fixed through the second metallic sheath 3-2, and the bottom of this second metallic sheath 3-2 has screwed hole; To make things convenient for the apparatus clamping, the first metallic sheath 3-1 and the second metallic sheath 3-2 process by stainless steel material.Shutoff film 2 adopts Polyester Fibers to process; Adopt sewing thread to be sewn on the support frame 1, can make fixing respectively at head, waist and the afterbody of support frame 1.
What technique scheme provided can be fixed in heart chamber/room according to damaged form adjustment self form with a kind of heart defect stopper.This stopper reasonable in design, the card at two of support frame 1 is smooth, and elasticity is suitable; Draw in that to emit recovery of shape property behind the conveyer device good, the length of this stopper and form can be adjusted automatically, and stent support power is good; Safe and reliable risk is little, and plugging effect is obvious.
The above only is the preferred implementation of this utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from this utility model know-why, can also make some improvement and replacement, these improvement and replacement also should be regarded as the protection domain of this utility model.
