Technical field
This utility model relates to a kind of vascular treatment equipment, specially vascular interventional treatment simulator.
Background technology
Endovascular temporary embolization is application selectivity or subselective angiographic technique, first after clear and definite pathological changes presentation, character, scope and degree, according to indication, carries out the treatments such as thromboembolism, Endovascular angioplasty and dabbling drug through inserting endovascular conduit.The disease of internal blood vessel the most multiple, scattered short section narrow and inaccessible.Long section is narrow or inaccessible, Small vessel, the narrow or Occlusion of exedens narrow or existing calcification are unsuitable for treatment, the contrast agent balloon inflation diluted with compression pump or hand push.The sacculus of inflation acts on narrow blood vessel, is allowed to expand.After expansion terminates, angiography to be checked, understand vasodilation situation, again measure the blood pressure difference of former stenosis area upper and lower to determine the effect of dilation therapy simultaneously.In order to reduce complication and prevention of restenosis, from preoperative daystart application medicament for resisting platelet aggregation, such as aspirin etc..Anticoagulant heparin to be used in art, the medicine such as postoperative 1～6 months Aspirins, persantins.Due to internal fibrinolysis activity, after thrombus obstruction blood vessel, many beginning at several hours is dissolved.The advantage of clot is to draw materials conveniently, and no antigen is not required to sterilization, and The book of Changes conduit injects, and is used for control hemorrhage compared with small artery, and inaccessible vascular time is from several thoughtful some months.Gelfoam can be sterilized, no antigen, can make different size of granule or little bar on demand, be easy to get, inexpensive, is widely used in thromboembolism, thin vessels, as hemorrhage in occlusion of bone tumors, vascular conditions and control etc..It is therefore proposed that the vascular interventional treatment simulator that service life is long.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, it is provided that vascular interventional treatment simulator.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model provides vascular interventional treatment simulator, and including support, each described internal stent is provided with several connecting holes arranged in a uniform, and is provided with several equally distributed elastic steelframes described in each two between support；Described support two ends are provided with the support member of arcuate structure, and described rack side wall is provided with the drug reservoir of semicircular structure.
As a kind of optimal technical scheme of the present utility model, described rack outer surface is coated with protecting film, and described protecting film is internally provided with the vesicle being connected to described support one end.
As a kind of optimal technical scheme of the present utility model, the middle part of described vesicle and described protecting film is provided with flow-guiding mouth, and described flow-guiding mouth one end is connected to mozzle.
As a kind of optimal technical scheme of the present utility model, described mozzle one end is provided with pressure-reducing ring, and described mozzle is internally provided with the slide bar that one end is connected with described flow-guiding mouth, and described slide bar surface is provided with control.
As a kind of optimal technical scheme of the present utility model, described control surface configuration has several inner frames being connected with described mozzle tube wall, and described inner frame surface configuration has several equally distributed metering holes.
This utility model is reached to provide the benefit that:
This utility model is a kind of simulation for vascular treatment, adapts to median size or big blood vessel, is not affected by limiting；After the hemodynamic changes such as the blood pressure determining displacement, degree and Branch blood feed situation and narrow upper and lower at blood vessel, foley's tube will not be exchanged into by angiography catheter；The protecting film that this equipment surface is arranged can be good at protecting its contacting with blood vessel; protect blood vessel; also blood vessel intervening equipment is protected; sacculus is placed in stenosis area; when blood flow flows through the mozzle of its inside; can make to support slowly to strut, it is ensured that blood flow unimpeded and stable, service life is long; inside drug reservoir; can place the medicine needing to treat internal blood vessel, medicine can dissolve in internal blood vessel, enters inside blood; reach therapeutic effect; the therapeutic effect of this equipment is good, and compact conformation is unlikely to deform.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains this utility model, be not used to limit this utility model.
Embodiment: as shown in Figure 1-2, this utility model provides vascular interventional treatment simulator, including support 3, each described support 3 is internally provided with several connecting holes 2 arranged in a uniform, and is provided with several equally distributed elastic steelframes 1 described in each two between support 3；Described support 3 two ends are provided with the support member 9 of arcuate structure, and described support 3 sidewall is provided with the drug reservoir 7 of semicircular structure.
Described support 3 outer surface is coated with protecting film 6, and described protecting film 6 is internally provided with the vesicle 8 being connected to described support 3 one end；The middle part of described vesicle 8 and described protecting film 6 is provided with flow-guiding mouth 5, and described flow-guiding mouth 5 one end is connected to mozzle 10；Described mozzle 10 one end is provided with pressure-reducing ring 4, and described mozzle 10 is internally provided with the slide bar 11 that one end is connected with described flow-guiding mouth 5, and described slide bar 11 surface is provided with control 12；Described control 12 surface configuration has several inner frames 14 being connected with described mozzle 10 tube wall, and described inner frame 14 surface configuration has several equally distributed metering holes 13.
In use, vessel support device is to use special alloy to this utility model, makes the cylindrical shape of different structure, is supported in angiostenosis lesion, is allowed to keep blood flow unobstructed.Hot memorial alloy eyelid retractor and making from swollen eyelid retractor；It is woven into cylindrical shape with stainless steel alloy silk, after putting into blood vessel, is supported in Endovascular due to metal elastic force.Bracing frame is coghill net eye-shaped, first on sacculus, puts into balloon inflation after blood vessel, makes eyelid retractor open and be supported in Endovascular.After bracing frame is placed in blood vessel, body is resistant to, and foreign reacts.In bracing frame, performance covers due to Fibrinogen, can form new intima soon, connect with the normal blood vessels inner membrance at eyelid retractor two ends, thus ensure the unobstructed of blood vessel.The application that match such as the main same balloon angioplasty of eyelid retractor, laser angioplasty and rotary-cut method.Place bracing frame, vessel open rate can be improved, reduce restenosis.The internal medicine placed of drug reservoir can selective arterial perfusion chemotherapy Drug therapy, the drug level of tumor by local can be increased, extend tumor cell with the time of contact of high concentration medicine, alleviate the whole body toxicity of medicine, the effect of chemotherapy can be improved.
