Abstract
The utility model discloses a kind of detachable bending interposing catheter, belong to technical field of medical instruments, it comprises the first conduit, the second conduit and bending conduit, first conduit is connected by bending conduit with the second conduit, wherein the first conduit is provided with branched pipe, described branched pipe side communicates with the first conduit, the tapered shape of opposite side.The crooked radian of described bending conduit is adjustable, is convenient to the enforcement of intervene operation.Compared with prior art, technique of the present utility model is simple, and production efficiency is high, and can improve the efficiency of selection of interposing catheter better, replaceable guide casing, reduces medical treatment cost greatly.
Description
Technical field
This utility model relates to a kind of interposing catheter, particularly relates to a kind of detachable bending interposing catheter.
Background technology
Interventional therapy operation is by means of interposing catheter by vessel lumen, focus is realized to the emerging medical skill of one of low wound Diagnosis and Treat.Compare with traditional medical skill, interventional therapy has the following advantages: easy and simple to handle; Due to the low-wound of interventional therapy, can avoid bringing huge misery to patient; Because its invasive, the position that routine operation can not arrive can also be arrived; Also relatively low compared with routine operation treatment medical expense, thus widely patient and doctor accepted.Present interventional therapeutic technique has been widely used in cardiovascular and cerebrovascular vessel radiography and narrow blood vessel plasty clinically.
Interposing catheter is one of main apparatus of endovascular temporary embolization, and it provides the transmission channel of other medical apparatus and instruments and medicine for interventional therapy.The structure of conduit can be divided into two parts, a part gos deep into longer one section of blood vessel to can be described as conduit and turn round control section, and operated the part controlling its intravasation by patient, another part is catheter proximal end, difformity is formed, to reach therapeutic purposes according to difference operation or demand.A few class can be divided into: the guiding catheter of Judkins class conduit, Amplatz class conduit, Backup class conduit and three dimensional catheter and some other specific type, doctor selects dissimilar conduit when interventional treatment operation according to the state of an illness of patient according to the form of calcification score conduit.The conduit of identical type is similar, and difference is catheter proximal end, because the artery size of patient is different or coronary opening position is variant.So same type catheter proximal end partial shape is similar, just size slightly difference so model is different, in order to satisfied different corrective surgery demand.
Percutaneous Coronary Intervention needs doctor to select appropriate catheter according to the radiography situation of patient's tremulous pulse and arteria coronaria, everyone tremulous pulse and arteria coronaria variant, carrying out smoothly of correct guarantee subsequent procedures selected by conduit.Existing interposing catheter, control section turned round by its conduit and catheter proximal end is integral structure, and doctor only can select conduit according to radiography situation and experience.If operation process finds that the conduit inserted is improper, so just need the conduit changing other models of the same type, change a whole set of conduit (turning round control section and catheter proximal end containing conduit), not only delay operating time, medical expense also increases, and operation risk also increases.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of detachable bending interposing catheter, repeatedly changes catheter type for solving, and solves the problem that repeatable operation seal wire is extracted out from conduit and the function reducing medical treatment cost.
The technical scheme that this utility model solves the problems of the technologies described above is as follows: a kind of detachable bending interposing catheter, and it comprises the first conduit, the second conduit and bending conduit, and the first conduit is connected by bending conduit with the second conduit; Described first conduit is provided with branched pipe, and described branched pipe side communicates with the first conduit, the tapered shape of its opposite side port.
Further, described first conduit is identical with the internal diameter of bending conduit with the second conduit.
Further, the crooked radian of described bending conduit is adjustable.
Further, described branched pipe is provided with closed sealing.
The beneficial effects of the utility model are: technique is simple, and production efficiency is high, and can improve the efficiency of selection of interposing catheter better, replaceable guide casing, reduces medical treatment cost greatly.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
In accompanying drawing, the list of parts representated by each label is as follows:
100, the first conduit, the 200, second conduit, 300, bending conduit, 400, branched pipe.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining this utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of detachable bending interposing catheter, it comprises the first conduit, the second conduit and bending conduit, and the first conduit is connected by bending conduit with the second conduit; Described first conduit is provided with branched pipe, and described branched pipe side communicates with the first conduit, the tapered shape of its opposite side port.
Further, described first conduit is identical with the internal diameter of bending conduit with the second conduit.
Further, the crooked radian of described bending conduit is adjustable.
Further, described branched pipe is provided with closed sealing.
Compared with prior art, the utility model has the advantage of, technique is simple, and production efficiency is high, and can improve the efficiency of selection of interposing catheter better, replaceable guide casing, reduces medical treatment cost greatly.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
