Abstract

Disclosed is a coaxial saccule thrombolysis conduit, aiming at putting forward a cerebrovascular disease treatment interventional material integrating the medicine thrombolysis, mechanical blood clot breaking down and saccule expansion with synchronous operations. The effective length of the utility model is 150 cm; the diameter of the farther end is 3F; the diameter of the closer end is 4F; the diameter of the utility model gradually becomes bigger from the farther end to the closer end with level and smooth transition; the conduit is composed of a conduit head, a conduit trunk and a conduit tail. The utility model is characterized in that the conduit is provided with three cavities and a saccule; the three cavities are coaxial. The thromoolysis medicine or other medicine is continuously pumped inside the three cavities from the tail end of the conduit, or the contrast agent is injected into the cavities during thrombolysis. Continuous pumping of the thrombolysis medicine during the operation is favorable for the synchronous operation of mechanical blood clot breaking down and resolving and the saccule expansion, and changes the shortcoming of previous repeated changing of conduits, guide wires and thrombolysis.

Description

A kind of coaxial sacculus thrombolysis catheter

Technical field:

A kind of coaxial sacculus thrombolysis catheter of this utility model relates to the therapeutic device for the treatment of cerebrovascular disease.

Background technology:

Ischemic cerebrovascular is commonly encountered diseases, frequently-occurring disease clinically, has sickness rate, disability rate, mortality rate three-hypers characteristics.Can use at present the method for cerebrovascular interventional therapy, allow revascularization at short notice, recover the blood supply of cerebral tissue, save greatly and be on the verge of downright bad neuron by the microtubular technology for the early stage patient of symptom.Yet the employed material great majority of cerebrovascular interventional therapy need import, and price is expensive, and many patients are unable to be born.Present alternative intervention material mainly is a microtubular, micro-wire, foley's tube, have special-purpose thrombolysis catheter both at home and abroad, the capsule of not dribbling is used for the real process of thrombolytic, must be replaced by foley's tube when running into narrow position and expand, when running into thrombosis and being difficult to dissolve, use the broken bolt of micro-wire machinery must pass through thrombolysis catheter, but thrombolytic drug is difficult to enter at this moment, because of the thrombolysis catheter tube chamber narrow and small, only can hold micro-wire, make that liquid is difficult to enter.And described foley's tube has catheter with double-cavity saccule at present, is used for support and implants forward and backward expansion narrow positions use, does not still have the special-purpose foley's tube of thrombolytic.In a word, use present intervention material both domestic and external, thrombolytic, mechanical broken bolt, balloon expandable can not be carried out synchronously, make the thrombolytic process not carry out continuously, spended time is long, and effect can not be affirmed, and the X-ray irradiation time is long, and is all unfavorable to patient and doctor.Run into patient's cerebral thrombosis and be associated with stricture of artery simultaneously in actual mechanical process, perhaps ectopic embolus antegrade blood flow thromboembolism is to trunk, or need be used in combination during difficult situation such as thrombosis of venous sinus, operating difficulties, and the treatment difficulty is big.

Summary of the invention:

The purpose of a kind of coaxial sacculus thrombolysis catheter of this utility model is to propose a kind of cerebrovascular treatment intervention material that medicine thrombolytic, mechanical broken bolt, balloon expandable can be carried out synchronously in one.150 centimetres of a kind of coaxial sacculus thrombolysis catheter effective lengths of this utility model, distal diameter 3F, proximal diameter 4F by thick as far as increasing closely gradually, seamlessly transits; Described conduit is by conductor housing, catheter stem, the conduit tail constitutes, it is characterized in that, described conduit contains three chambeies and a sacculus, described three chambeies are coaxial, wherein center cavity holds micro-wire, the subcenter chamber links to each other with sacculus, and the force (forcing) pump that links to each other by tail end fills sacculus to expand narrow blood vessel, and the periphery chamber is a filling cavity, 1.5 ~ 3 millimeters of described balloon diameter, 10 ~ 20 millimeters of length directly link to each other with the periphery chamber with the subcenter chamber, and described sacculus is positioned at the head of conduit, from 5 millimeters of the center cavity opening parts of end of conduit, sacculus connects the opening in subcenter chamber, and there is mark's labelling at the sacculus two ends, is convenient to observe under perspective the position that sacculus should be placed.The position that the periphery chamber connects sacculus is arranged in order the opening that the string side opening is the periphery chamber later on, and thrombolytic drug flows into lumen of vessels by tapping.The afterbody of described conduit is a trifid structure, respectively corresponding three chambers.Tail end by conduit in the thrombolytic operating process constantly pumps into thrombolytic drug or other medicines, or injection of contrast medium, the continual thrombolytic drug that pumps in the process of operation is convenient to the broken bolt thrombolytic of machinery balloon expandable is carried out synchronously, changes conduit, seal wire, thrombolytic before having changed repeatedly.

Description of drawings:

Fig. 1 is the structural representation of a kind of coaxial sacculus thrombolysis catheter of this utility model.

The specific embodiment:

As shown in Figure 1,150 centimetres of a kind of coaxial sacculus thrombolysis catheter effective lengths of this utility model, distal diameter 3F, proximal diameter 4F by thick as far as increasing closely gradually, seamlessly transits; Described conduit is made of conductor housing 1, catheter stem 2, conduit tail 3, it is characterized in that, described conduit contains three chambeies and a sacculus, described three chambeies are coaxial, its external diameter is no more than 1 millimeter, and wherein center cavity 4 holds also injectable contrast agent of micro-wire, under the micro-wire guiding, conduit is positioned over the optional position of lumen of vessels, and micro-wire has broken bolt effect concurrently simultaneously; Subcenter chamber 5 links to each other with sacculus 6, the force (forcing) pump that links to each other by tail end fills sacculus 6 to expand narrow blood vessel, periphery chamber 7 is a filling cavity, tail end by conduit in the thrombolytic operating process constantly pumps into thrombolytic drug or other medicines, or injection of contrast medium, the continual thrombolytic drug that pumps in the process of operation is convenient to the broken bolt thrombolytic of machinery balloon expandable is carried out synchronously.1.5 ~ 3 millimeters of described sacculus 6 diameters, 10 ~ 20 millimeters of length directly link to each other with periphery chamber 7 with subcenter chamber 5, described sacculus 6 is positioned at the head of conduit, from 5 millimeters of the center of end of conduit accent distances, there is mark's labelling 8 at sacculus 6 two ends, are convenient to observe under perspective the position that sacculus 6 should be placed.The position that periphery chamber 7 connects sacculus is arranged in order string side opening 9 later on, and this side opening 9 is communicated with periphery chamber 7, and thrombolytic drug flows into lumen of vessels by tapping.The afterbody 3 of described conduit is a trifid structure, respectively corresponding three chambers.
