In figure: 1 is conduit, 2 is seal wire, and 3 is Rotary-table, and 4 is cylinder cap, and 5 is guiding groove.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be further described.
A kind of vein blood vessel stripper, comprise conduit 1, seal wire 2, described conduit 1 is can the hollow pipe of anti-certain pressure, and seal wire 2 is positioned at conduit 1 and can walks at conduit 1, and the end of seal wire 2 is by connecting Rotary-table 3, Rotary-table 3 is threaded connection cylinder cap 4, there is a through duct in the middle of described Rotary-table 3 and cylinder cap 4, can seal wire 2 be passed through therebetween
Described seal wire is 2-3 root, has the guiding groove 5 guiding seal wire walking, described seal wire diameter d in described conduit
0, guiding groove internal diameter d
1following formula is met with catheter diameter D:
Wherein A to be value be 1 ~ 2.5 constant, d in formula
0, d
1, the unit of D is millimeter.
Because the diameter of seal wire is thinner, and there is certain elasticity and plasticity, thus in traveling process, when running into varix too severity can cause insertion smooth, easily make the front end of seal wire bend and produce distortion, the seal wire produced after distortion cannot continue to introduce forward, second seal wire now can be adopted to continue traveling forward, second seal wire position is in the catheter different from the first seal wire, can avoid continuing in identical position to occur distortion, if after still there is distortion in second seal wire, the 3rd seal wire can be adopted to continue traveling, 3rd seal wire position and first in the catheter, two seal wires are all different, can avoid occurring distortion in identical position, guiding groove is arranged in conduit, axial symmetry can be become to arrange, for guiding each seal wire in the different position traveling of conduit.
Wherein, conduit, seal wire successfully have critical effect with the relative internal diameter size of guiding groove for guiding, because seal wire is thinner, if the internal diameter of guiding groove is too tiny, then frictional force can cause difficulty in walking, if and the internal diameter of guiding groove is excessive, then effectively cannot guide seal wire, even namely deform in guiding groove inside.Conduit is also very important with the relative internal diameter size of guiding groove, if conduit is excessive relative to guiding groove internal diameter, then in vein, the resistance of traveling is comparatively large, brings misery to patient, otherwise, if conduit is too small relative to guiding groove internal diameter, then can increase the difficulty of processing.Inventors performed simulation experiment for this reason, adopt internal diameter close to the plastic tube simulated blood vessel of vein, after adopting baking or pinching and rub and make it be out of shape, injection therein has the liquid state of certain viscosity with simulate blood, stripper of the present invention is imported simulation practical guide and strip off process, through test of many times, unexpected discovery works as seal wire diameter d
0, guiding groove internal diameter d
