Abstract
The utility model provides a special catheter for portal vein interventional therapy, which can conveniently carry out the operation of portal vein interventional therapy. The special catheter for portal vein interventional therapy is provided with a first bent part with an 28 to 32 DEG angle at the position of 0.6 to 1.2 cm away from the catheter tip; the position of one side of the first bent part having 4 to 6 cm away from the catheter tip is provided with a second bent part with a 55 to 65 DEG angle, and the bent direction of the second bent part is opposite to that of the first bent part; the position of the second bent part having 4 to 6 cm away from the catheter tip is provided with a third bent part with a 110 to 130 DEG angle, and the bent direction of the third bent part is opposite to that of the second bent part; and the bending angles of the first bent part, the second bent part and the third bent part are flat and stay in a same plane. Because having the similar shape to the portal vein of a human body, the special catheter for portal vein interventional therapy is applied to the operation of portal vein interventional therapy, greatly facilitates the operation, improves the success ratio, and reduces the operation time.
Description
Technical field
This utility model belongs to medical apparatus and instruments, is specifically related to a kind of dedicated conduits that is used for the portal vein interventional therapy.
Background technology
Interventional therapeutic technique is increasingly extensive in clinical practice, development rapidly, especially in recent years in portal vein, carry out interventional therapy, as thrombolytic art, regional perfusion's chemotherapy art etc. in branch of portal vein Embolization, the portal vein, in treatment of diseases such as primary hepatocarcinoma, portal hypertension, play a greater and greater role.But, the special-purpose intervention therapeutic apparatus of portal vein is not arranged as yet so far because that this technology is carried out the time is shorter relatively.Dedicated conduits particularly, the portal vein interventional therapy conduit of clinical practice now mostly is tremulous pulse conduits such as Naja.
The human body portal system has particular structure, and portal vein is merged by the superior mesenteric vein and the splenic vein, is divided into left and right branch again in hepatic portal portion.Can divide four types according to the portal vein form: (1) normal type: the portal vein trunk is a left side and right in hepatic portal punishment, and a right traveling to the right is divided into right anterior branch and right back.Account for whole crowds' 85%.(2) I form variation: the portal vein trunk is trident at the hepatic portal place, directly is divided into a left side, right anterior branch and right back.(3) II form variation: the portal vein trunk sends right back earlier, continues to be divided into a left side to upper right line and props up and right anterior branch.(4) III form variation: the portal vein trunk sends right back earlier, omits crooked diagonal then to the left, develops into a left side and props up, and right front propping from a left side propped up.This 3 form variation is a portal vein inborn variation common type.(5) other variations.Comprise that a portal vein left side horizontal segment lacks as and right of portal vein lacks as.The portal vein bifurcation angle is subjected to patient's form, influence such as physiological status, age and variation is bigger, and majority is the angle of nearly acute angle, and special portal vein bifurcation angle at hepatitis, liver cirrhosis patient mostly is acute angle, and the portal vein bifurcated of variation also mostly is acute angle.Therefore this has increased difficulty for clinical carrying out by the portal vein interventional procedure of liver puncture, and ductus arteriosuss such as Naja can't arrive the target vessel of branch of portal vein sometimes owing to factors such as design angle, shapes, or because tension force is bigger, causes operative failure.Therefore the clinical conduit that presses for a kind of special use of portal vein intervention is conveniently to carry out interventional treatment operation in the portal vein.
The utility model content
In view of this, in order to address the above problem, this utility model provides a kind of portal vein interventional therapy dedicated conduits, can carry out interventional treatment operation in the portal vein easily.
The purpose of this utility model is achieved in that portal vein interventional therapy dedicated conduits, and it is 28-32 ° first bending section that angle is arranged apart from catheter tip 0.6～1.2cm place; It is 55-65 ° second bending section that first bending section has angle away from catheter tip one side 4-6cm place, and the bending direction of second bending section is opposite with first bending section; It is 110-130 ° the 3rd bending section that second bending section has angle away from catheter tip one side 4-6cm place, and the bending direction of the 3rd bending section is opposite with second bending section; The bent angle of described first bending section, second bending section and the 3rd bending section is level and smooth and in same plane.
Further, described first bending section is apart from catheter tip 1cm;
Further, the angle of described first bending section is 30 °;
Further, described second crooked position in first bending section away from catheter tip one side 5cm place;
Further, the angle of described second bending section is 60 °;
Further, described the 3rd crooked position in second bending section away from catheter tip one side 5cm;
Further, the angle of described the 3rd bending section is 120 °;
Further, described portal vein interventional therapy dedicated conduits total length is 80-100cm.
Portal vein interventional therapy dedicated conduits of the present utility model is because therefore its form and the pylic plesiomorphism of human body are applicable to and carry out interventional treatment operation in the portal vein that greatly handled easily, raising success rate reduce operating time.
Other advantages of the present utility model, target, to set forth in the following description to a certain extent with feature, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be by following description, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing this utility model is described in further detail, wherein:
Accompanying drawing shows the structural representation of this utility model most preferred embodiment.
The specific embodiment
