Description

Ganglioside GM_3 microtubular
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of ganglioside GM_3 microtubular.
Background technology
It is known that,Ganglioside GM_3 microtubular is the new type medical equipment for the cardiovascular and cerebrovascular disease that cannot be performed the operation by high risk,It is introduced that,Because brain and spinal cord are the nerve centers of human body,The lesion of its medium and deep or complexity such as intracranial aneurysm,Carotid sinus fistula and vascular malformation etc. often cannot operative treatments,Or operating difficulty is big,Sequelae is serious,In recent years,Neurology Interventional Radiology continue to develop and function admirable polymeric catheter appearance,Open the New Times of endovascular treatment of intracranial aneurysms,At present,Clinically ganglioside GM_3 microtubular is mainly used in being transfused in neural blood vessel diagnostic preparation-such as contrast agent and therapeutic article-such as turn,It is main by catheter block,Catheter body and Marking ring are constituted,The conduit volume surrounding is polyamide elastomer,Polyamide/polyamide elastane composite material,Inner layer material is polytetrafluoroethylene (PTFE),Catheter body surface scribbles hydrophilic coating,Conduit seat material is polyamide elastomer,Mark ring material is platinum,Auxiliary shell material is polyamide,The catheter body front end is provided with Marking ring,UNICOM is fixed in rear end with catheter block,Its deficiency is：In infusion process, due to catheter body midfoot support power poor performance, and the holding capacity of the angle form of head does not reach requirement, causes to operate not only inconvenient, and, also substantially prolongs operating time.
The content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, there is provided a kind of simple structure, ganglioside GM_3 microtubular that is easy to operate, conveying quick shortening operating time.
The present invention solves the technical scheme that is used of above-mentioned technical problem：
A kind of ganglioside GM_3 microtubular, including catheter block, catheter body and double labelling ring, it is characterized in that the catheter body is by external coating, middle casing play and the PTFE inner liners of internal layer are formed by fixedly connecting, the superficies are attached with hydrophilic coating, the casing play is fixedly and coaxially connected and is formed by the titanium-nickel wire braiding rack of near-end and the stainless steel wire braiding rack of distal end, so that the conductibility of the good radial support power of the titanium-nickel wire braiding rack offer of near-end and power, the stainless steel wire braiding rack of distal end provides good head end angle form holding capacity, external coating outside the titanium-nickel wire braiding rack is PEBAX layers, it is beneficial to and good supportive is provided, external coating outside the stainless steel wire braiding rack is layer of polyurethane, good compliance is provided.
The present invention has the advantages that simple structure, easy to operate, conveying is quick, shorten operating time due to using said structure.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Reference：Catheter block 1, catheter body 2, double labelling ring 3, titanium-nickel wire braiding rack 4, stainless steel wire braiding rack, 5PEBAX layers 6, layer of polyurethane 7.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings：
A kind of ganglioside GM_3 microtubular,Including catheter block 1,Catheter body 2 and double labelling ring 3,The catheter block 1,The annexation of catheter body 2 and double labelling ring 3 is same as the prior art,This is not repeated,It is characterized in that the catheter body 2 is by external coating,Middle casing play and the PTFE inner liners of internal layer are formed by fixedly connecting,The superficies are attached with hydrophilic coating,The casing play is fixedly and coaxially connected and is formed by the titanium-nickel wire braiding rack 4 of near-end and the stainless steel wire braiding rack 5 of distal end,So that the titanium-nickel wire braiding rack 4 of near-end provides the conductibility of good radial support power and power,The stainless steel wire braiding rack 5 of distal end provides good head end angle form holding capacity,External coating outside the titanium-nickel wire braiding rack 4 is PEBAX layers 6,It is beneficial to and good supportive is provided,It is beneficial to and is moved in especially tortuous blood vessel,External coating outside the stainless steel wire braiding rack 5 is layer of polyurethane 7,Good compliance is provided,It is beneficial to and avoids causing adhesion to vascular wall.
The present invention is in Clinical practice, hand-held catheter block, turn to be conveyed is placed on catheter body distal end, inserted through arteries again, during turn delivered into lesion vesselses knurl, because catheter body distal end weaves rack using stainless steel wire, it is ensured that the form holding capacity of catheter body head, turn is set to be sent to diseased region quickly.
The present invention has the advantages that simple structure, easy to operate, conveying is quick, shorten operating time due to using said structure.
