Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the A portion enlarged diagram in Fig. 1.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the blood vessel microtubular with variable flexibility in embodiment mainly comprises tubular axis 1, described tubular axis 1 is set to near-end near one end of operator, tubular axis 1 near-end is connected with joint 2, in illustrated embodiment, described joint 2 adopts female Luer 2, this female Luer 2 for connecting other armarium as syringe, or enters microtubular for the conduit or injecting fluid inserting seal wire; Tubular axis 1 is set to far-end for a section of entering patient vessel; Described tubular axis 1 adopts flexible deformable material to make, and the hardness of tubular axis 1 is distally reduced along the length direction of tubular axis 1 gradually by near-end.Such design makes blood vessel microtubular be easier to manipulation, contributes to while the stability keeping microtubular near-end and ease for operation, microtubular far-end is more easily inserted and navigates within to wriggle and forked vascular system.
The change of described tubular axis 1 flexibility is reflected by the change of the Shore D hardness number of corresponding site.In this utility model embodiment, described tubular axis 1 is 75 ~ 30 by near-end to the shore D firmness change scope of far-end.Preferably, the shore D hardness of described tubular axis 1 near-end is 60 ~ 75, and the shore D hardness of tubular axis 1 far-end is 30 ~ 40.Involved shore D value can use trackability evaluation system Trackability Evaluation System to measure, and comprises temperature control, clamping device, trackability evaluation system control panel, manual, grip force meter and tremulous pulse and vascular pattern.
In this utility model, described flexible deformable material is nylon block copolymer.Trade mark as produced by French Arkema Specialty Polyamides is the nylon block copolymer of PEBAX.More preferably, described flexible deformable material is the block copolymer of nylon and polyethylene oxide.
As shown in Figure 2, in this utility model embodiment, the distal tip of described tubular axis 1 is provided with developing mark ring 3, developing mark ring 3 is sleeved on tubular axis 1 far-end and is adhesively fixed with cyanoacrylate adhesive, and developing mark ring 3 is for helping the location of the far-end of blood vessel microtubular in patient body and injection for curing thing when implementing treatment.Described developing mark ring 3 adopts iridium alloy to be that 2-20%w/w platinumiridio is made, and more preferably adopts wherein iridium alloy to be 10%w/w platinumiridio.In addition, described tubular axis 1 far-end is equipped with crown cap 4, and the top of described top cap 4 is set to circular arc.
Tubular axis 1 aperture dimension in this utility model is unified on whole tubular axis 1, and usual internal diameter is 0.025-0.35 inch, and being enough to meet diameter is passing through of the seal wire of 0.021 inch, and first-selected diameter is 0.25 inch.The length available of tubular axis 1 is 100cm ~ 150cm, preferably 110cm ~ 130cm.
Blood vessel microtubular in this utility model can be used for as liver, heart, the arteries in kidney and uterus, also may be used for the blood vessel of tumor or muscular tumor, apply its mode of carrying out treating and comprise injection anticoagulant, the embolism microball containing fluorescence indicator, and the blood vessel image of therapeutic goal position.
