Abstract
The utility model discloses a novel spiral bit type artery balloon dilatation catheter, belongs to the technical field of medical equipment, and aims to solve the problems that predilation and post-dilation balloons of the conventional balloon dilatation catheter difficultly penetrate through the vascular cavity of an occlusion part and tortuous lesion. According to the novel spiral bit type artery balloon dilatation catheter, the top of a balloon is connected with a spiral bit with an axial hollow tube hole; and the axial hollow tube hole of the spiral bit is connected with a balloon internal catheter. The novel spiral bit type artery balloon dilatation catheter is simple in structure and is suitable for percutaneous transluminal angioplasty treatment and artery occlusion checking of percutaneous coronary intervention.
Description
Technical field
This utility model belongs to the sacculus dilating catheter of a kind of puncture shaping surgery treatment obstruction of artery in the technical field of medical instruments.
Background technology
Along with the continuous development of medical apparatus and instruments and the raising day by day of people's medical level, to treating the obstruction of artery interventional therapy and checking that the specification requirement of used sacculus dilating catheter is also increasingly high.In known technology, existing sacculus dilating catheter mainly is to be connected to form by sacculus, female luer, conduit and connecting leg, but limit by its structure; Especially cardiac stent predilation and back dilating sacculus can only be through improving material compliance and reduce balloon diameter as far as possible and improve its trafficability characteristic, but its trafficability characteristic still receives the restriction of the following factor, like inaccessible pathological changes; Be positioned at true intracavity though can confirm seal wire, because the occlusion tube chamber is too narrow and small, occlusion site is comparatively hard in addition; So can't pass through pathological changes, thereby cause the intervene operation failure, for another example tortuous, the stenotic lesion place of lesions extreme; Sacculus just can't pass through, especially for the back dilating sacculus, because it has used non-conforming materials; Its compliance is poor, and slight tortuously also pass through than difficulty brings inconvenience to use.
Summary of the invention
In order to overcome the deficiency of prior art, solve its predilation of existing sacculus dilating catheter and the back dilating sacculus passes through the problem that occlusion lumen of vessels, tortuous lesions are difficult to pass through.The purpose of this utility model provides a kind of simple and practical, can in interventional therapy operation, pass through occlusion lumen of vessels, tortuous lesions, stenotic lesion place smoothly, new-type sacculus dilating catheter easy to use.
This utility model addresses the above problem the technical scheme that is adopted:
A kind of novel auger hair style aortic sac dilating catheter, it is provided with: sacculus, conduit, female luer, portion is connected with the augers of axial hollow pore in the top of sacculus, and the axial hollow pore of augers is to connecting the sacculus inner catheter.
Above-mentioned novel auger hair style aortic sac dilating catheter, said augers is the column type augers, or the pyramid type augers.
When this utility model uses; In the interventional therapy operation; During through occlusion lumen of vessels, tortuous lesions, stenotic lesion place, rotatable foley's tube, the augers of sacculus head end can be close to blood vessel wall and " creep into " forward; Thereby auxiliary sacculus passes through diseased region smoothly, thereby realizes the predilation and the back expansion of diseased region.
Because technique scheme has been adopted in this utility model design, solved its predilation of existing sacculus dilating catheter and back dilating sacculus effectively and passed through the problem that occlusion lumen of vessels, tortuous lesions are difficult to pass through.Show through the test result on trial; It compared with prior art; Have simple and practical; Can in interventional therapy operation, pass through occlusion lumen of vessels, tortuous lesions, stenotic lesion place smoothly, advantage such as easy to use is applicable to the puncture shaping surgery treatment and the inspection obstruction of artery of interventional therapeutic technique.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is described in further detail:
Fig. 1 is the structure diagram of this utility model embodiment.
Fig. 2 is the structure for amplifying sketch of another embodiment pyramid type augers of this utility model.
Each label is in the accompanying drawing: 1 column type augers; 1-1 pyramid type augers; 2 sacculus; 3 conduits; 4 female luer.
The specific embodiment
Like accompanying drawing 1 illustrated embodiment, this utility model is provided with: sacculus 2, conduit 3, female luer 4, and one is connected with the column type augers 1 of axial hollow pore in the top of sacculus 2, and the axial hollow pore of column type augers 1 is to connecting the inner catheter of sacculus 2.
Referring to accompanying drawing 2 embodiment, the augers of this utility model or be pyramid type augers 1-1.
