Description
Technical field
The utility model is related to a kind of microtubular axis, belong to interventional medical utensil.
Background technology
Interventional treatment refers to using televimonitor high technology equipment, by opening a duck eye at a certain position of human body, so
Blood vessel in patient body is stretched into a microtubular afterwards, repaired, expanded, dredged the minimally invasive intracavity operation treatment of work, making
For effective therapy of multiple types vascular diseases, achievement highly visible has been obtained.
With the continuous development of interventional treatment, the raising of surgical ability and serious complex lesions are constantly challenged, as
Medical microtubular in interventional procedure is improved successfully due to that can reduce the complexity of vessel inner lesion interventional procedure
Rate, while by angiorrhoxis risk when reduction interventional treatment, reducing risk of the patient in complicated interventional treatment, having become
Intervene the important instrument of operation.
Although microtubular used at present may be implemented to stretch into blood vessel in patient body, the works such as repaired, expanded, dredged
With, but additional function is still relatively simple, with the development of medical science and technology, existing microtubular cannot meet using need
It asks.Therefore, it should a kind of new technical solution be provided and solved the above problems.
Invention content
The purpose of this utility model is：Against the above deficiency, a kind of microtubular reasonable for structure, using effect is good is provided
Axis.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of microtubular axis, one end are connect with hand-held pedestal, including pipe shaft body, and the pipe shaft body includes being arranged concentrically
Inner and outer tubes, metal knitted stratum reticulare, the gold on metal knitted stratum reticulare are provided between said inner tube outer wall and outer tube wall
Belong to silk crosspoint to be welded and fixed, the outer surface of the outer tube is provided with depth mark, and the depth mark is coated in conduit table
The calibration loop in face, the calibration loop are made of thick ring and thin ring, and the thin ring is arranged between adjacent thick ring, the pipe axis sheet
Body axial direction is divided into four changeover portions, and the pipe shaft body between adjacent two thick rings is a changeover portion, four changeover portions
Direction of the hardness from close to hand-held pedestal to far from hand-held pedestal successively decrease.
Further technical solution is：
More than two thin rings are uniformly arranged between adjacent thick ring, the spacing between adjacent thin ring is 4-10 ㎜.
The pad at wire cross on the metal knitted stratum reticulare is circular ring shape, ellipse or spiral shape.
The outer surface of the outer tube is equipped with one layer of hydrophilic coating.
Due to the application of above-mentioned technical proposal, the utility model has the following advantages that compared with prior art：
1, the microtubular axis of the utility model, due to being provided with metal knitted stratum reticulare between outer wall of inner tube and outer tube wall,
And on metal knitted stratum reticulare wire cross spot welding fix, such structure design, can improve catheter wall intensity and
The ability of bend resistance enhances the operability of conduit.
2, the microtubular of the utility model, due to being provided with depth mark in the outer surface of outer tube, and depth mark is by applying
The thick ring and thin ring for overlaying on catheter surface are constituted, and thick interannular, can be in order to quickly distinguishing the overall depth of insertion, thin ring away from big
Spacing is small, is convenient for accurate perception depth distance.
3, the microtubular axis of the utility model makes it have more since pipe axis is divided into the different changeover portion of multiple hardness
Good flexibility, fold resistance and tracing property can rapidly reach the diseased region of blood vessel, to blood vessel when reducing interventional treatment
Injury.
