The beneficial effect that the technical scheme that this utility model embodiment provides is brought is: this utility model embodiment provides a kind of anus Fistulous tract angiographic catheter, this anus Fistulous tract angiographic catheter one end is elasticity cecum, after inflation, volume expands and outage on it expands a little, not only be convenient to contrast agent discharge, also by enlarged volume, contrast agent disperseed more.Meanwhile, metal hose adds anus Fistulous tract angiographic catheter hardness and can bend according to the structure in fistula road.In addition, during use anus Fistulous tract angiographic catheter two-layer conduit between can inflate a little, not only increase its hardness, and its hardness can be changed according to the blowing pressure, also make outer conductor have certain elasticity, avoid damaging the tissue around fistula road, the gas after being used to complete between the two-layer conduit of sucking-off, reduce its volume, be convenient to it to extract out from fistula road.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anus Fistulous tract angiographic catheter that this utility model embodiment provides.
In figure: 1 catheter body, 2 syringe interfaces, 3 inner conductors, 4 outer conductors, 5 elasticity cecums, 6 outages, 7 gas injection interfaces, 8 metal hoses.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model is described in further detail.
See Fig. 1, this utility model embodiment provides a kind of anus Fistulous tract angiographic catheter, comprises catheter body 1, and catheter body 1 one end (head end) is provided with syringe interface 2; Particularly, the long 10-30cm of catheter body 1, the diameter of catheter body 1 is 1-3mm.Wherein, catheter body 1 forms by inner conductor 3 is nested with outer conductor 4, and have gap between inner conductor 3 and outer conductor 4 and form sealing mechanism, two conduits form interlayer and can inflate inward, and after inflation, inner conductor 3 and outer conductor 4 are out of shape very little.Catheter body 1 other end (tail end) is elasticity cecum 5, elasticity cecum 5 is evenly equipped with multiple outage 6.Wherein, elasticity cecum 5 is communicated with the interlayer formed between inner conductor 3 and outer conductor 4, expand a little after inflation and outage 6 on it expands (outage 6 need design according to the shape of elasticity cecum 5), elasticity cecum 5 is compared with inner conductor 3 and the stressed easier deformation of outer conductor 4.Wherein, outage 6 is communicated with inner conductor 3 (being communicated with elasticity cecum 5 inwall), but it is not communicated with outer conductor 4, and outage 6 is uniformly distributed on the end and sidewall of elasticity cecum 5.Catheter body 1 one end (head end) is also provided with gas injection interface 7, gas injection interface 7 is located on outer conductor 4 sidewall and it is communicated with outer conductor 4, but be not communicated with inner conductor 3, namely gas injection interface 7 is communicated with the interlayer formed between inner conductor 3 and outer conductor 4, elasticity cecum 5 can be made to expand a little by gas injection interface 7 gas injection.In addition, gas injection interface 7 also can arrange the structures such as the clip of stopper or the clamping gas injection interface 7 preventing from leaking gas.
