Abstract
The utility model relates to a disposable abnormal path single disk in heart and blood vessel and a double-disk blocking device. A cylinder and the disk are telescopic net-shaped structure, a plurality of path annular protuberances are arranged on the outer surface of the cylinder, and the longitudinal surface of the cylinder forms a wave shape. The waist of the double-disk blocking device is also provided with an inward stacked part, when the double-disk blocking device is used for blocking holes, the contact point of a tube cavity and the double-disk blocking device forms a wave-shaped occlusion to enhance supporting force and the collapse preventing force. The close contact and fixing in the hole cavity enhances the blocking performance and the reverse quit preventing force. The utility model is suitable for blocking abnormal paths of patent ductus arteriosus, arteriovenous fistula, atrial septal defect, etc.
Description
This utility model relates to tube chamber shutoff device in a kind of medical human, especially a kind of single-deck and double plate stopper of being made by the high resiliency shape-memory alloy wire.
During abnormal passage diseases such as treatment patent ductus arteriosus, adopt operation usually, closely during the last ten years, also adopt interventional technique, carry out shutoff with stopper.Basic demand to stopper is: 1. reliable at the vestibule internal fixation, prevent from oppositely to withdraw from; 2. supporting ﹠ stablizing does not subside; 3. contact with periphery closely, do not leak blood.Usually adopt the single-deck stopper to carry out shutoff for the infundibulate vestibule, then adopt the shutoff of double plate stopper usually for the window-shaped vestibule.Existing single-deck stopper structure is as figure A2-a, and shown in the figure A2-b, its cylinder partly is flat.Existing double plate stopper structure is as figure B2-a, and shown in the figure B2-b, the waist between its cylinder and the double plate is flat, and is slick.When being used for the A2-c as figure, during the shutoff vestibule of figure shown in the B2-c, the plane cylinder is restricted its contact area with the chamber wall, thereby makes support force and prevent that the power of subsiding is all limited.Slick waist is difficult to adapt to the vestibule of different wall or the vestibule of inhomogeneous wall thickness, thereby the tight contact in vestibule is fixedly had certain influence.
The purpose of this utility model is: abnormal passage single-deck and double plate stopper in a kind of disposable use heart and the blood vessel are provided, enable to strengthen support force and the anti-ability of subsiding with tube chamber, the tight contact that is increased in the vestibule is fixed, and improves sealing characteristics and the anti-reverse power of withdrawing from.
The technical scheme that realizes this utility model purpose is: in a kind of disposable use heart and blood vessel in the abnormal passage single-deck stopper, its cylinder top has one and goes up dish, cylinder reaches to go up to coil and is telescopic network structure, some roads circular protrusion is arranged, the vertical surperficial undulate of cylinder on the cartridge outer surface of this single-deck stopper.
The technical scheme that realizes this utility model purpose can also be: in a kind of disposable use heart and blood vessel in the abnormal passage double plate stopper, its cylinder upper and lower respectively has one and goes up dish and a lower wall, and cylinder reaches and goes up dish, lower wall is telescopic network structure.Cartridge outer surface at this double plate stopper has some roads circular protrusion, the vertical surperficial undulate of cylinder.
Can inwardly concave at the waist between dish and the lower wall on this double plate stopper, form a circle and inwardly fold into part.
Owing to adopt technique scheme, on the damaged surface of single-deck and double plate stopper, make some roads circular protrusion, with prior art center pillar body portion is flat comparing, the contact area of this utility model and sufferer tube chamber increases, thereby support force and the anti-power of subsiding have been strengthened, and the undulate interlock, the contact that has increased in vestibule is fixed, and has improved sealing characteristics and the anti-reverse power of withdrawing from.Inwardly concave a circle overlapping portion again at the waist of double plate stopper, make it by suitably the opening up and down of upper and lower dish, adapting to variation and uneven wall thickness, thereby the tight contact that more is increased in the vestibule is fixed.

Figure A3-a and figure A3-b are depicted as an embodiment of this utility model single-deck stopper.Have on one on the top of the cylinder 1 of this single-deck stopper and to coil 2, cylinder 1 and go up all telescopic network structure of dish 2 for making by high resiliency Ni-Ti silk.Five road shape projections are arranged on the outer surface of cylinder 1, also can be one or three road projections, make vertical surface of cylinder 1 be the waveform shown in the figure A3-b according to different needs.With this utility model single-deck stopper shutoff infundibulate vestibule as figure A3-c shown in.
Figure B3-a and figure B3-b are depicted as an embodiment of this utility model double plate stopper, respectively have dish 2 and lower wall 3 on one in the upper and lower of the cylinder 1 of this double plate stopper, cylinder 1 and go up all telescopic network structure of dish 2, lower wall 3 for making by high resiliency Ni-Ti silk.
On the outer surface of the cylinder 1 of this double plate stopper annular projection is arranged, the quantity of projection is decided as required, the vertical surperficial undulate of cylinder 1.Waist 4 between the upper and lower dish of this double plate stopper inwardly concaves, and forms a circle and inwardly folds into part.With this utility model double plate stopper shutoff window-shaped vestibule as figure B3-c shown in.
The operating process of this utility model single-deck device stopper is as follows: see also figure A1-a, figure A1-b, figure A1-c links the lower end 6 of stopper on the seal wire 7, and with in the seal wire 7 insertion conduits 8, pulling down seal wire 7 can draw in stopper in the conduit 8, and intravascular is delivered to the sufferer place with conduit 8 heads, and reuse seal wire 7 is released stopper from conduit 8, stopper restores to the original state, make it to block just the sufferer hole, stop blood flow to pass through, thereby reach the purpose of treatment.The operating process of this utility model double plate stopper is identical with the single-deck stopper, specifically sees also figure B1-a, and figure B1-b is shown in the figure B1-c.
This utility model single-deck and double plate stopper all are applicable to the shutoff of abnormal passages such as patent ductus arteriosus, arteriovenous fistula and atrial septal defect.
