Abstract
The utility model discloses a controllable blood vessel embolism device, composed of a screws steel wire (1), a push conduit tube (2), an embolism object bracket (3). The embolism object bracket (3) is composed of a nylon wire (4) connected with the top of the push conduit tube (2). The utility model can be used in the embolism of the patent arterial conduit tube and the cerebral arteries, the kidney arteries, the embolism of the lung arteries and the vein fistula. The utility model can control directly the embolism part at the outside through the nylon wire. The utility model has the advantages of convenient operation, high safety and high reliability.
Description
This utility model relates to a kind of controllable type vascular occluding device, belongs to medical apparatus and instruments.
Through closed catheter patent ductus arteriosus, abroad attempt since the sixties.Its method is the total tremulous pulse of ductus arteriosus, lung that femoral artery puncture pushes to the long steel wire of special use through the moving thigh of thigh ventral aorta, thoracic aorta, descending aorta, patent successively; Again through the offside femoral vein, with special snare push to the total tremulous pulse of lung entangle the total tremulous pulse of lung steel wire after femoral vein pull out.Then Ivoeon(polyvinyl formal foam plastics) stopper is forced into from femoral artery along steel wire, and the reuse conduit pushes to the ductus arteriosus place of patent, with the ductus arteriosus of thromboembolism patent.This method is compared with opening thorax artery closed catheter art, has reduced patient's misery, is considered to be better than operating selection.However, still there are many shortcomings in this method, and as inserting steel wire and conduit through arterypuncture, arterial injury is bigger, and needs burst artery and vein two a places puncture; Used snare operation easier is big; The embolus uncompressed is difficult for by femoral artery, and misoperation can cause femoral artery to tear, so that causes danger; Not tight as the embolus thromboembolism, in case come off, or thromboembolism is improper, and thromboembolism is promptly failed.
The purpose of this utility model is at the problems referred to above, designs a kind of easy to operate, safe in utilization, reliable controllable type vascular occluding device of therapeutic effect.
Main points of the present utility model are to have increased by an embolus support on the basis of former cardiac catheter, by nylon wire support is involved in the top that pushes conduit, and the Ivoeon stopper is fixed on it, accurately enter the thromboembolism position by pushing conduit and nylon wire control stopper.
Fig. 1 controllable type vascular occluding device sketch map.
Fig. 2 controllable type vascular occluding device user mode sketch map.
With reference to Figure of description, now structure of the present utility model and use operating process are described below:
The utility model controllable blood vessel embolism device (referring to accompanying drawing 1) is made up of spiral wire (1), propelling movement conduit (2) and embolus support (3). The embolus support is the stainless steel pipe box, and two ends are turnup slightly upwards, and the one end has an aperture, and a nylon wire (4) is walked around aperture, passes from push conduit, and the embolus support is involved in pushing the conduit top. Use operating process of the present utility model is earlier thin nylon wire to be passed by the aperture on the embolus support, again according to the diameter of vascular embolization, Ivoeon is cut into different sizes, be fixed on the embolus support with thin silk thread, then nylon wire is passed from push conduit, the embolus support is involved in pushing the conduit top. For making embolus smoothly by blood vessel, reduce the endangium damage, with compression mould the Ivoeon compression is the garden column. Press the percutaneous puncture tremie method through femoral venous puncture (referring to accompanying drawing 2), spiral wire is pushed to femoral vein successively, common iliac vein, inferior caval vein, the atrium dextrum, right ventricle, the total artery of lung, the arterial duct of patent, descending aorta, abdominal aorta, again ready Ivoeon stopper is delivered in the patent arterial duct with the propelling movement conduit along spiral wire, the arterial duct of embolism patent, the all operations were process is carried out under perspective, as the Ivoeon plug position not to or expand after size uncomfortable, the nylon wire of available push tail end of conduit is controlled it and is put in place or pull out and again change stopper. When auscultation, two-dimensional ultrasound inspection confirm the embolism success, hold one of nylon wire by pushing tail end of conduit, nylon wire is pulled out external, withdraw from successively again spiral wire and push conduit.
This utility model is compared with existing vascular occluding device, has remarkable advantage.This utility model has designed the embolus support, at external direct control position that embolus arrives, has reduced the danger that embolus comes off by nylon wire on it; Embolus compression back is used, can avoid arterial intima; This utility model inserts from the femoral vein one-time puncture, has reduced patient's misery, and ill children operation year order is relaxed, and the time gets timely medical treatment the child in advance; Got rid of snare, easy to use, simple to operate, shortened operating time.This utility model not only can be used for the thromboembolism of patent ductus arteriosus, also can be used for cerebral arteries, renal artery, Hepatic artery (through arterypuncture), and lung is moving---and the thromboembolism of quiet fistula etc. can be got timely medical treatment more patient under the very little situation of misery.
Now elaborate by 1 pair of specific embodiment of the present utility model of accompanying drawing.
Spiral wire among the embodiment (1) is long to be 250cm, and pushing conduit (2) is the 8F polyfluortetraethylene pipe, and long is 125cm.Embolus support (3) is the rustless steel pipe box, the about 0.9mm of internal diameter, and length can be selected according to the length at different thromboembolisms position.Nylon wire length is about 2 times that push catheter length.
Claims (2)
1, a kind of controllable type vascular occluding device comprises spiral wire (1) and pushes conduit (2) that it is characterized in that described vascular occluding device is provided with an embolus support (3), this support is a rustless steel pipe box, and the one end has an aperture.
2, vascular occluding device according to claim 1 is characterized in that embolus support (3) is to be involved in the top that pushes conduit (2) by nylon wire (4).
