Abstract
The utility model discloses a kind of adopt radio frequency can Ink vessel transfusing cutting melt sacculus dilating catheter, comprise cutting and melt sacculus dilating catheter body, cutting is melted sacculus dilating catheter body and is comprised sacculus and foley's tube, wherein, one end of foley's tube connection sacculus prelum is built-in with a tinsel be connected with RF ablation device; Further, one end that tinsel connects RF ablation device is relatively drawn from the expansion end of foley's tube; Meanwhile, exit wiry is connected with the expansion head of foley's tube.The beneficial effects of the utility model: be provided with a tinsel be connected with RF ablation device by melting in sacculus dilating catheter in cutting, reach the cutting of lesion vessels wall and melt dual function, when making operation, blood vessel elastic fibrous tissue necroses the retraction function that follows the string, reach the object for the treatment of coronary stenosis, after coronary stenosis is treated, Ink vessel transfusing does not stay foreign body, avoids the risk of the complication after stenter to implant.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically, relate to a kind of adopt radio frequency can Ink vessel transfusing cutting melt sacculus dilating catheter.
Background technology
In recent years, the rise of interventional therapeutic technique is that the treatment of cardiovascular disease have found better approach.Cardiac intervention treatment refers to carries out cardiopathic Diagnosis and Treat by percutaneous catheter techniques.
Current state intervenien therapy coronary heart disease and peripheral blood vessel typically use sacculus dilating catheter and arteria coronaria/peripheral blood vessel mounting system.The such as patent No. is the balloon system patent of CN201370879Y, its coronary saccule dilating catheter (nylon 12) development point material is platinum, this dilating catheter far-end also scribbles hydrophilic coating, and fore-end is coaxial configuration, is disposable product.This device scope of application is the expansion in the coronary stricture portion of the cases such as coronary heart disease, and effect is that percutaneous coronary expansion makes the lumen of vessels at angiostenosis position expand.
But, current this sacculus exist sacculus withdraw from after due to blood vessel tissue elasticity retraction cause the problem that blood vessel is again narrow, ways of addressing this issue is normally put into after coronary artery bracket is washed open at this expansion again and is forever retained in Ink vessel transfusing.This treatment is if there is early stage and the situation such as advanced thrombus and restenosis, then after stenting, client need carries out the operation of balloon dilatation and stenting implantation again.But again re-starting balloon dilatation and stenting implant surgery phase treatment difficulty will strengthen, and restenosis incidence rate is higher.Because Ink vessel transfusing has metallic foreign body, thus increase stenter to implant Post operation support and fracture and the complication risk such as thrombosis.。
For the problem described in above-mentioned correlation technique, at present effective solution is not yet proposed.
Utility model content
For problem above-mentioned in correlation technique, the utility model proposes a kind of adopt radio frequency can Ink vessel transfusing cutting melt sacculus dilating catheter, effectively can solve that patient is postoperative causes the problem that blood vessel is again narrow due to blood vessel tissue elasticity retraction, thus effectively improve success rate of operation and surgical effect.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of adopt radio frequency can Ink vessel transfusing cutting melt sacculus dilating catheter, comprise cutting and melt sacculus dilating catheter body, the foley's tube that sacculus dilating catheter body comprises sacculus and is connected with described sacculus is melted in described cutting, wherein, one end that described foley's tube connects sacculus prelum is built-in with a tinsel be connected with RF ablation device, and one end that described tinsel connects described RF ablation device is relatively drawn from the expansion end of described foley's tube, simultaneously, described exit wiry is connected with the expansion head of described foley's tube.
The beneficial effects of the utility model: be provided with a tinsel be connected with RF ablation device by melting in sacculus dilating catheter in cutting, reach the cutting of lesion vessels wall and melt dual function, when making operation, blood vessel elastic fibrous tissue necroses the retraction function that follows the string, reach the object for the treatment of coronary stenosis, after coronary stenosis is treated, Ink vessel transfusing does not stay foreign body, avoids the risk of the complication after stenter to implant.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is that the structural representation of sacculus dilating catheter is melted in the Ink vessel transfusing cutting according to this utility model embodiment.
In figure:
1, dilating catheter body; 2, sacculus; 3, foley's tube; 4, sacculus prelum; 5, RF ablation device; 6, tinsel.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.Obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of this utility model protection.
As shown in Figure 1, a kind of according to embodiment of the present utility model adopt radio frequency can Ink vessel transfusing cutting melt sacculus dilating catheter, comprise cutting and melt sacculus dilating catheter body 1, the foley's tube 3 that sacculus dilating catheter body 1 comprises sacculus 2 and is connected with described sacculus 2 is melted in described cutting, wherein, one end that described foley's tube 3 connects sacculus prelum 4 is built-in with a tinsel 6 be connected with RF ablation device 5, and, one end that described tinsel 6 connects described RF ablation device 5 is relatively drawn from the expansion end of described foley's tube 3, simultaneously, the exit of described tinsel 6 is connected with the expansion head of described foley's tube 3.
Conveniently understand technique scheme of the present utility model, below by way of in concrete occupation mode, technique scheme of the present utility model is described in detail.
When specifically using, this device is transported to the lesion sacculus prelum pressurization of blood vessel, RF ablation device makes blood vessel wall partial elastic fibrous tissue necrose and the retraction function that follows the string after starting the several seconds simultaneously, thus reach the object for the treatment of coronary stenosis, the maximum feature of this device is that after coronary stenosis treatment, Ink vessel transfusing does not stay foreign body, thus effectively prevent the complication risk after stenter to implant.
In sum, by means of technique scheme of the present utility model, a tinsel be connected with RF ablation device is provided with by melting in sacculus dilating catheter in cutting, reach the cutting of lesion vessels wall and melt dual function, when making operation, blood vessel elastic fibrous tissue necroses the retraction function that follows the string, reach the object for the treatment of coronary stenosis, after coronary stenosis is treated, Ink vessel transfusing does not stay foreign body, avoids the risk of the complication after stenter to implant.
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.
