Abstract
The present invention provides a kind of thrombus removing conduit and the thrombus remove device with it, belong to thrombus disposal facility technical field, wherein, it includes: catheter body that thrombus, which removes conduit, at least one thrombus recovery port and at least one reflection liquid mouth are offered on side wall, and there is the catoptric arrangement towards blood vessel on the reflection liquid mouth；Injection pipe is set in the inside of the catheter body, has at least one liquid ejection outlet, catoptric arrangement of the liquid ejection outlet towards the reflection liquid mouth；After liquid for removing thrombus is sprayed from the liquid ejection outlet towards the reflection liquid structure, reflected towards the thrombus of blood vessel；Thrombus of the invention removes conduit, and the liquid for removing thrombus is contacted with endovascular thrombus again after reflection, so that injection liquid is not directly impacted blood vessel, reduces the damage to vascular wall, vascular wall will not be made to generate interlayer.
Description
Technical field
The present invention relates to thrombus disposal facility technical fields, and in particular to a kind of thrombus removing conduit and the blood with it
Bolt remove device.
Background technique
Artery help conveys the blood rich in oxygen and various nutriments to each position of body.When artery of lower extremity blocks
Afterwards, enough blood or oxygen can not be just obtained, peripheral arterial disease (PAD) is at this moment called.Peripheral arterial disease be due to
Lipid Plaque is formed on vascular wall, patch is mainly made of cholesterol, calcium and fibr tissue.Patch becomes arterial lumen
Narrow or even entirely shut, Oligemia, lower limb just lack enough oxygen and maintain eubolism.
Currently, still facing very big challenge in the Thrombectomy of PAD, often wanted in patient's emergency intervention treatment
Thrombus removing is used, medical worker will hold accurately rescue time, slewing when carrying out thrombus clear operation to patient
Lesion locations save operating time, and thrombus is removed rapidly and efficiently is external.When removing the thrombus of lesion vessels, simultaneously also
Protect the blood vessel of lesion.
In current thrombus treatment scheme, using two kinds of mainstream therapeutic schemes, one kind is stent in the treatment, in angiogenesis
The position of pathological change of thrombus is implanted into bracket, and advantage is that treatment time is fast, and clinical effectiveness is obvious, and disadvantage is that stenter to implant is that foreign matter is planted
Enter, need to take antithrombotic reagent for a long time after the implantation, bracket is once being implanted into can not take out, if condensing thrombus at bracket again only
Do bridging scheme.Second method is that the lesion occurred in thrombus is embedded to thrombolysis catheter, utilizes the drug on thrombolysis catheter
Spray orifice continues to discharge thrombolytic drug to lesion, and disadvantage is that thrombolytic effect is slow, and the period is long.
It the shortcomings that based on above-mentioned conventional thrombus sweep-out method, mechanical removal thrombus method or later thrombus will be become will remove
Mainstream development direction.Since blood vessel is that in layer, each layer is all to fit closely together, mechanical means uses medical fluid
Thrombus is impacted, it is desirable that reduce damage target blood to the greatest extent while smashing thrombus, avoid that vascular lamina is washed open to be formed
Interlayer causes complication.
However, in the method that existing machinery thrombus is removed, when being impacted using injection liquid to thrombus, injection liquid
After ejiction opening injection, it is directly impinging blood vessel, be easy that blood vessel is caused to damage or is stimulated, complication is caused.
Summary of the invention
Therefore, the technical problem to be solved in the present invention is that thrombus sweep-out method in the prior art is overcome, using jet stream
Liquid directly sprays blood vessel, is easy to cause blood vessel the defect of damage, so that injection liquid can be improved to blood by providing one kind
The thrombus of the impact injury of inside pipe wall removes conduit.

Towards the catoptric arrangement of the reflection liquid mouth；
After liquid for removing thrombus is sprayed from the liquid ejection outlet towards the reflection liquid structure, towards blood vessel
The thrombus of inner wall reflects.
As a preferred embodiment, the thrombus recovery port setting exists, for removing the liquid of thrombus, by reflection and blood
Bolt after touch, then by thrombus reflection falls back to the corresponding position in catheter body.
As a preferred embodiment, the liquid ejection outlet and the thrombus recovery port, are respectively positioned on the thrombus reflex port
Front end.
As a preferred embodiment, the liquid ejection outlet has multiple.
As a preferred embodiment, the end of the injection pipe is equipped with ring pipe, and multiple liquid ejection outlets are equably
It is arranged on the ring pipe.
As a preferred embodiment, the reflection liquid mouth have it is multiple, each reflection liquid mouth at least with one
The liquid ejection outlet is opposite.
As a preferred embodiment, the thrombus recovery port has multiple, and the lateral wall around the catheter body is uniformly set
It sets.
As a preferred embodiment, the catoptric arrangement includes:
Reflecting surface forms incident angle with the liquid ejection outlet, by preset incident angle by liquid from the liquid
The thrombus of body jet port towards blood vessel is reflected；
One side on the outside of the close catheter body of the reflecting surface is arranged in poly- liquid level, has towards thrombus direction and extends
Inclined-plane.
Thrombus remove device provided by the invention removes conduit including thrombus described in any one of above scheme.
As a preferred embodiment, the rear end that the thrombus removes conduit is connected with the peristaltic pump for aspirate thrombi.
Technical solution of the present invention has the advantages that
