Detailed description of the invention
In order to be better understood from the technical solution of the utility model, it is described in detail, below in conjunction with accompanying drawing, the detailed description of the invention that this utility model provides.
This utility model provides a kind of novel guiding system for ultrasound-guided percutaneous research of transcatheter closure of ventricular septal defect, including conduit and matched seal wire, as shown in Figure 1, described conduit is hollow conduit, the conduit difference according to internal diameter, it is divided into 5F, two kinds of models of 6F, a passage passed through for matched seal wire along its length it is provided with in it, described conduit includes the first straightway AB section being sequentially connected with, arc line shaped section BCD section and the second straightway DE section, the extended line of described second straightway DE section and the angle of the first straightway AB section are 45 degree��135 degree,
Described seal wire diameter is 0.028-0.040 inch, formed by piece wirerope braiding of the intensive winding of finer wire, its embedded described wirerope is made up of the main part being sequentially connected with and soft head two parts, the part of the seal wire that the main part of wirerope is corresponding with the head i.e. respectively main part of seal wire and soft head, the main part diameter of described wirerope is 0.025 inch, enough support forces are provided for seal wire entirety, the soft head diameter of described wirerope is 0.01 inch, to keep the flexibility of this part seal wire, can ensure that described seal wire soft head will not change the specific form of catheter head when inserting described conduit.
First straightway AB segment length 150cm of described conduit, described arc line shaped section BCD section is 1/4��3/4 circular arc, it is preferred that be 1/2 circular arc; The diameter of this circular arc is 0.5��3cm, it is most preferred that diameter be 1cm.
Described second straightway DE segment length 0.5��1cm, the extended line of described second straightway DE section and the angle of the first straightway AB section are 90 degree.
In this specific embodiment, it is preferable that the diameter of described seal wire is 0.035 inch, total length is 260cm; The length of the main part of described seal wire is 254cm; The length of the soft head of described seal wire is 6cm; Be provided with density bullet position in the centre of described seal wire, the described density bullet distance of positions is 155cm from the soft head of seal wire distance foremost.
When described seal wire inserts and arrives density bullet position in conduit, the soft head of described seal wire exposes conduit 2��3cm foremost, and to attempt by ventricular septal defect, catheter head will not change shape because the hardness of the soft head of seal wire supports simultaneously.
The above-mentioned using method for the novel guiding system of ultrasonic guidance Heart septal defects percutaneous percutaneous transcatheter closure that this utility model provides is as follows:
When described guiding system is applicable to patients with ventricular septal defect operation, specifically include following steps:
(1) femoral artery puncture, is placed into the Arterial sheath matched with conduit and seal wire that diameter is 6F, and on the left of body surface measurement point of puncture to breastbone, the 2nd intercostal distance, is labeled as operating distance.
(2) take described guiding system, described seal wire is inserted in conduit, and conduit and seal wire are sent into internal through Arterial sheath together, enter internal after, A/C, continue push seal wire, after arriving operating distance, fixing seal wire, push conduit and also arrive operating distance; Owing to the main part hardness of seal wire is relatively big, so being gradually inserted along with seal wire, makes catheter head stretch gradually, namely make whole conduit linearly type, facilitate conduit to pass through relatively narrow and small femoral artery, iliac artery, it is to avoid conduit scratch tremulous pulse; After tube insertion depth arrives operating distance, the head of conduit and seal wire is positioned at thicker aortic arch all simultaneously, and owing to the soft head of seal wire is soft, now the head of conduit recovers arc line shaped originally; Now it is rotated further by conduit, adopts the ultrasonic head end that can find conduit solid shape; For common strip conduit, ultrasonic just to switch to the conduit of long strip type when carrying out tangent plane detection and could find the position of conduit, and described conduit considerably increases the accuracy of supersonic sounding.
(3) under ultrasound detection, duct direction is adjusted so that it is opening, towards aortic arch lesser curvature side, pushes seal wire, can enter ascending aorta by aortic arch; Now push conduit along seal wire and enter ascending aorta, exit seal wire, make catheter head recover arc line shaped; Ultrasonic display aorta long axis view, adjusts duct direction, passes through aortic valve; Owing to catheter head highest point is arc-shaped, so than the common strip conduit aortic valve more easily by continuous opening and closing.
Catheter position is adjusted under the aorta long axis view of ultrasonic display, anxious of five chambeies, short axis view are observed repeatedly, make catheter opening towards interventricular septum direction, insert seal wire and arrive described density bullet position, now the soft head of seal wire exposes conduit 2��3cm foremost, to attempt by ventricular septal defect, catheter head will not change shape because the hardness of seal wire supports simultaneously;Adjust tube insertion depth and direction under ultrasound guidance, and repeatedly push seal wire to pass through ventricular septal defect; Once ultrasonic discovery seal wire is by ventricular septal defect, can continuing to push forward by seal wire, owing to seal wire head is soft, after encountering Evaluation of Right Ventricular Wall, seal wire can bend in arcuation, it is to avoid damage right ventricle; It is then log out conduit, retains seal wire, select stopper and corresponding induction system according to ventricular septal defect size, send into induction system along seal wire, send into the backed off after random seal wire of induction system, namely adopt usual manner to carry out plugging operations through induction system afterwards.
Obviously, above-described embodiment is only for clearly demonstrating example, and is not the restriction to embodiment. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here without also cannot all of embodiment be given exhaustive. And the apparent change thus extended out or variation are still among protection domain of the present utility model.
