Abstract
The utility model discloses a double guide wire catheter comprising a catheter body, wherein the catheter body consists of a thick section used for being penetrated by two guide wires and a thin section used for being penetrated by only one guide wire; the front end of the thin section is provided with a port; the transition position of the thick section and the thin section is provided with a side opening; the front end of the thin section is shaped like a spherical cap; and the position, close to the side opening, of the thick section, is provided with a mark line. The double guide wire catheter can lead in two guide wires by one time, reduces the inserting times of the catheter into a blood vessel, has short time consumption, high efficiency and small radiation amount on doctors and patients, and is conductive to the health of the doctors and the patients.
Description
Technical field
This utility model relates to a kind of conduit that can penetrate two seal wires.
Background technology
In the inferior genicular artery narrow treatment process of vascular surgery, in the time of need carrying out the balloon expandable treatment for many lesion vesselses, the method that adopts is that each lesion vessels is placed conduit respectively usually, introduces the seal wire location, separately balloon expandable.The shortcoming of this kind way is: need carry out balloon expandable to every lesion vessels, therefore need penetrate conduit to every lesion vessels, elapsed time is long, efficient is low, and it is big that doctor and patient accept quantity of X-rays X, influenced doctor and patient's body health; And conduit inserts blood vessel often, has increased the probability of injured blood vessel, especially the time through inferior genicular artery three crotches, and injured blood vessel wall especially easily, even artery dissection appears.
The utility model content
The technical problems to be solved in the utility model provides a kind of pair of wire catheter, can penetrate two seal wires by this conduit, two seal wires penetrate two lesion vesselses respectively and position, and expand respectively along the sacculus that seal wire enters, thereby finish dilation therapy, elapsed time is short, efficient is high.
For addressing the above problem, a kind of pair of wire catheter that is provided comprises catheter body, and its construction features is: catheter body by thick section that penetrates for two seal wires and only the thin segment that penetrates of seal wire of confession form, the front end of thin segment is provided with port, and the transition position of thick section and thin segment is provided with the side mouth.
After adopting said structure, earlier a guiding seal wire is penetrated in the conduit, with conduit penetrate lesion vessels at this moment this guiding seal wire enter a root disease and become blood vessel, another root seal wire can be penetrated from the side mouth from thick section and pass, make another root seal wire enter another lesion vessels, withdraw from conduit then, respectively two sacculus are introduced, respectively two lesion vesselses are carried out dilation therapy along seal wire.This shows that this utility model can once import two seal wires, reduced the number of times of conduit insertion blood vessel, elapsed time is short, efficient is high, and it is little that doctor and patient accept quantity of X-rays X, helps doctor and patient's body health.
As improvement of the present utility model, the leading section of thin segment is the spherical crown shape, the blood vessel wall of easy damaged lesion vessels not when its front end enters lesion vessels.
As further improvement of the utility model, thick section goes up by the proximal hole place and is provided with mark line, when this utility model being inserted inferior genicular artery three crotches, can make thick section transition position accurately arrive this position with thin segment, help two seal wires and enter two lesion vesselses respectively.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sketch map under this utility model user mode.
The specific embodiment
Two wire catheter as shown in the drawing, comprise catheter body 1, catheter body 1 is the nylon axle body that has the rustless steel braiding structure of standard, catheter body 1 is made up of thick section that penetrates for two seal wires and the thin segment that only penetrates for a seal wire, and thick section upward leans on proximal hole 3 places to be provided with mark line 4, and the leading section of thin segment is the spherical crown shape, be provided with port 2 at the coronal leading section of ball, thick section and thin segment rounding off, transition position is provided with side mouth 3 apart from the about 10cm of thin segment leading section at this transition position.
As shown in Figure 2, when the lesion vessels balloon expandable treatment of doing inferior genicular artery three crotches, in conduit, penetrate earlier guiding seal wire specification, this utility model is penetrated inferior genicular artery, when mark line is positioned at inferior genicular artery three crotches, another seal wire is penetrated, and such two seal wires enter two lesion vesselses respectively.
Claims (3)
1. two wire catheter, comprise catheter body (1), it is characterized in that: catheter body (1) is made up of thick section that penetrates for two seal wires and the thin segment that only penetrates for a seal wire, and the front end of thin segment is provided with port (2), and the transition position of thick section and thin segment is provided with side mouth (3).
2. pair wire catheter according to claim 1 is characterized in that: the leading section of thin segment is the spherical crown shape.
