Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of three chamber many side openings dual balloon catheters.
Background technology
Blood vessel embolism is the common disease in cardiovascular disease, and as cerebrovascular cerebral infarction etc., its disability rate, fatality rate are high.At present, the Therapeutic Method for this type of disease mainly contains medicine thrombolytic, machinery is got bolt etc.
From the effect of current clinical treatment, the effect that medicine thrombolytic and machinery are got bolt is not very desirable.
The subject matter of medicine thrombolytic is embodied in needs whole body administration, this complication that easily causes bleeding.And in thrombolytic process, the easy less blood vessel of clog downstream diameter after embolus volume-diminished.
The subject matter that machinery is got bolt is embodied in catching device and catches and in the process of embolus, easily destroy embolus, thereby produces less embolus.After catching device is caught embolus, also easily make embolus produce broken in extraction process, tiny embolus can continue to stop up tiny blood vessel.The close contact of catching device and blood vessel wall also likely can vascular endothelial cell injury, produces other complication.
Through retrieval, CN102698354A discloses a kind of application for a patent for invention of the dual balloon catheter for thrombolytic, and it comprises connecting device, stress anemostat, push rod, sacculus, catheter tip section, inner tube and seal wire.Described push rod is hollow structure; Described inner tube is in the inner chamber of described push rod and the inner chamber of described sacculus, and the far-end of described inner tube and catheter tip section fix; Described connecting device has first interface and the second interface.Described sacculus is two balloon structure, and comprise the first sacculus, the second sacculus and make described the first sacculus and connecting duct section that described the second sacculus communicates with each other, and described sacculus has micropore, thereby when introducing medicinal liquid by described the second interface, described the first sacculus and described the second sacculus can expand, to form closed treating space between described the first sacculus and described the second sacculus, and medicinal liquid can enter described closed treating space by described micropore.After treatment finishes, the waste liquid forming in described closed treating space can be by described micropore by slowly sucking-off, and then is discharged from by described the second interface.Thus, the probability contacting with human normal tissue for the medicinal liquid of thrombolytic significantly reduces, its deficiency is: unreasonable structure, after thrombolytic, thrombolytic resolves into little embolus through medicinal liquid, while being sucked out by micropore, the little embolus that part is greater than micropore also remains in blood vessel, can not be eliminated, also easily by blood, flow in the blood vessel of minor diameter, cause secondary to stop up.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to operate, to get bolt convenient, improve efficiency of thrombolysis, save thrombolytic drug, reduce side effect, reduce medical expense, avoid causing three chamber many side openings dual balloon catheters of secondary thromboembolism.
This utility model solves the technical scheme that its technical problem adopts:
A kind of three chamber many side openings dual balloon catheters, comprise conduit, distal balloon catheter, proximal balloon and sacculus joint, it is characterized in that being provided with obstruction seal wire and seal wire joint, described sacculus joint comprises drug infusion joint, distal balloon catheter joint and proximal balloon joint, distal end of catheter is provided with distal balloon catheter and proximal balloon successively to near-end, in distal end of catheter, be fixed with obstruction seal wire, near-end is provided with distal balloon catheter joint and proximal balloon joint, in conduit, be provided with distal balloon catheter connecting pipe and proximal balloon connecting pipe, catheter wall between described distal balloon catheter and proximal balloon is provided with medicinal liquid and portals, distal balloon catheter connecting pipe one end is connected with distal balloon catheter, the other end is connected with distal balloon catheter joint, proximal balloon connecting pipe one end is connected with proximal balloon, the other end is connected with proximal balloon joint, block seal wire through drug infusion joint implantation catheter intracavity, when distal end of catheter outlet can be blocked, keeping between drug infusion joint and two sacculus run micropore to have living space communicates, being beneficial to thrombolytic drug conduit micropore through between two sacculus flows out, this utility model is when clinical practice, conduit is passed to thrombosis, by distal balloon catheter joint, the full contrast agent of distal balloon catheter and proximal balloon joint are filled to contrast agent to proximal balloon, make distal balloon catheter and proximal balloon fix and can have an X-rayed lower development location with the blood vessel at thrombosis two ends respectively, again by perfusion in drug infusion joint conductive pipe, the medicinal liquid of medicinal liquid on catheter wall portals to flow out and contacts with endovascular thrombosis and thrombus, increase the thrombolytic drug holdup time, improve local drug concentration, after thrombolytic, near-end balloon pressure is discharged completely, under the full state of distal balloon catheter, withdraw conduit, remaining outmoded thrombosis is pulled out external.
This utility model is owing to adopting said structure, have rational in infrastructure, easy to operate, to get bolt convenient, improve efficiency of thrombolysis, save thrombolytic drug, reduce side effect, reduce medical expense, avoid causing the advantages such as secondary thromboembolism.
