Abstract
The utility model provides an intracranial support conveying conduit, which comprises a conveying section and a disassociated section. The conveying section is made of homogenous plastics, a framework made of stainless steel wires by weaving is arranged inside the conduit wall of the conveying section, hydrophilic films are coated on both the outer conduit wall and the inner conduit wall of the conveying section, a valve joint is arranged at one end of the conveying section while the other end is connected with the disassociated section, the outer wall of the conduit in the disassociated section is conical, the thick end of the conical conduit outer wall is connected with the conveying section while a mark is arranged on the outer wall of the thin end, the disassociated section is made of plastics, a platinum ring is wound inside the conduit wall of the disassociated section, and a hydrophilic film is coated on the inner wall of the disassociated section. The intracranial support conveying conduit in use can convey a support to a narrow position of a blood vessel to be released, and reduces the risk of difficulty in arranging in place due to excessively large resistance in the process of conveying the support caused by distortion of the blood vessel.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of intracranial stent delivery conduit.
Background technology
Entocranial artery (comprising internal carotid artery, vertebral artery) is narrow to be the basic cause of disease of cerebral infarction or transient ischemic attack, has sickness rate, disability rate, mortality rate three-hypers characteristics.In case morbidity will bring white elephant to family and society, and still there is not miracle cure at present both at home and abroad for the patient who does not in time go to a doctor.Have only those patients that can before narrow vascular occlusion, go to a doctor to enjoy effectively treatment--cerebrovascular interventional therapy.The support that is used for intracranial treatment stricture of artery at present has two kinds: promptly, and balloon expandable stent and self-expandable stent.The self-expandable stent softness easily by the tremulous pulse of distortion, arrive narrow positions, yet it costs an arm and a leg, postoperative restenosis rate height, is difficult to be accepted by medical personnel and patient, is not easy to popularize.Balloon expandable stent has that quality is hard, compliance is poor, is difficult to arrive shortcomings such as narrow positions by the tremulous pulse of distortion.Yet its adherent performance is good, and the postoperative restenosis rate is low, and especially low price enjoys numerous medical personnels and patient parent to look at.
The special-purpose balloon expandable stent of the intracranial that uses is bare bracket at present, directly under the micro-wire guiding support is pushed to the intracranial narrow positions during use.Because of support exposes, when its blood vessel through extremely twisting or fold, when perhaps running into harder speckle, " fish mouth phenomenon " to occur, promptly the far-end of support will open, and shovel is gone into inner membrance firmly, support can not arrive narrow positions, have to abandon operation, be that the doctor is in very how-do-you-do for this reason, allows the patient suffer economic loss simultaneously.Therefore, how allowing the sacculus expandable stent arrive narrow positions smoothly, is a difficult problem at present, does not still have the way of properly settling.
Summary of the invention
The purpose of this utility model provides a kind of intracranial stent delivery conduit, can the narrow positions that support is delivered to blood vessel be discharged by conduit, reduces because of buckling of vessel, and resistance is excessive in the support course of conveying, the risk that support is difficult to put in place.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the intracranial stent delivery conduit, it is characterized in that: described conduit comprises the transportation section, free section, the material of transportation section is the homogenizing plastics, the tube wall inside of transportation section is provided with the skeleton that is formed by the stainless steel silk braiding, all scribble hydrophilic film on the outer tube wall of transportation section and the inner tubal wall, one end of transportation section is provided with valve interface, the other end is connected with free section, and the conduit outer wall of free section is coniform, and its butt end is connected with the transportation section, the outer wall of thin end is provided with mark's labelling, the material of free section is plastics, and the tube wall inside of free section is wound with the platinum circle, scribbles hydrophilic film on the inwall of free section.
Beneficial effect:
Use intracranial stent delivery conduit described in the utility model, this conduit is soft, has certain elasticity simultaneously, all scribbles hydrophilic layer inside and outside the tube chamber, has the superslide performance.Its free section is coniform, when running into distortion, folding tremulous pulse or artery plaque, just can easily cross, because of it has the inner surface of superslide, when support by the time will very light, be unlikely to produce obstruction and feel, to such an extent as to difficulty of transportation.The tail end of transportation section has the interface with " Y " valve.Can be used as guiding catheter separately and use, also can in the 8F guiding catheter, use.The tube wall of transportation section conduit is made of the homogenizing plastics, is coated with on the outer wall with hydrophilic film, and tube wall inside is provided with the skeleton that is formed by the stainless steel silk braiding, can increase the intensity of conduit and turn round control, and make it to tolerate higher injection pressure; Inwall scribbles the hydrophilic film coating, can prevent thrombosis.The remote port place of free section conduit is provided with mark's labelling, is convenient to observe under perspective the position, exact position that distal end of catheter should be put.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
This utility model intracranial stent delivery conduit as shown in Figure 1, described conduit comprises transportation section 1, free section 2, conduit total length 100cm, external diameter 2mm, internal diameter 1.5mm, transportation section 1 long 90cm wherein, free section 2 long 10cm, the material of transportation section 1 is the homogenizing plastics, and the tube wall inside of transportation section 1 is provided with the skeleton that is formed by the stainless steel silk braiding, all scribbles hydrophilic film on the outer tube wall of transportation section 1 and the inner tubal wall, one end of transportation section 1 is provided with valve interface 3, the other end is connected with free section 2, and the conduit outer wall of free section 2 is coniform, and its butt end is connected with transportation section 1, the outer wall of thin end is provided with mark's labelling 4, the material of free section 2 is plastics, and the tube wall inside of free section 2 is wound with the platinum circle, scribbles hydrophilic film on the inwall of free section 2.
Intracranial stent delivery conduit described in the utility model, transportation section 90cm, the skeleton part is contained in tube wall inside, mainly plays a supportive role.Free section 10cm, tube wall inside is wound with the platinum circle, has with the buoyant effect of blood flow, and is very soft.When carrying out at first managing the near-end that free section is delivered to the artery stenosis section when intracranial stent is inserted, through this pipe support is delivered to narrow positions then, dilating sacculus then, the release support gets final product, easy to operate, can effectively save support and insert the spent time of process, the more important thing is the irradiation time that reduces ray, reduce the risk that the long-time irradiation of ray damages patient.
