Description
Technical field
The invention belongs to medical instruments field, more particularly, to a kind of vein blood vessel stripper and its method of exfoliation.
Background technology
Varication is due to the factors such as hypostasis, vein tube wall weakness, and caused vein is tortuous, a kind of blood of expansion
Pipe disease.At present, typically treated using the method for high ligation, endarterectomy, conventional great saphenous vein blood vessel strips off at present
Device usage is, in operation, in great saphenous vein near-end otch, stripper is delivered into near-end from great saphenous vein distal end insertion tube chamber,
Promoted by proximate, simultaneously cut off vein in distal incision, exposure when can not continue to promote, femoral vein is imported in great saphenous vein
Vein to be stripped off is drawn at place, is then slowly pulled out, and strips off whole great saphenous vein trunk, and this method inversely pushes away along great saphenous vein
OK, during implementation, due to barriers such as venous valve, lesion vesselses or because varix is too severe to cause insertion not
Freely, it can not need to increase otch halfway smoothly by stripper from near-end is distally delivered to and guide stripper up, repetition was equally performed the operation
Journey, increase patient pain, doctor's labor intensity and operating time.
The content of the invention
The invention provides a kind of vein blood vessel stripper and its method of exfoliation, can efficiently carry out vein blood vessel and strip off.
Completely technical scheme is the present invention：
A kind of vein blood vessel stripper, including conduit, seal wire, described conduit for can anti-certain pressure hollow tube, lead
Silk is in conduit and can lead walking in pipe, the end connection round estrade of seal wire, and round estrade is connected through a screw thread cylinder
Cap, there is the duct of an insertion among described round estrade and cylinder, seal wire can be passed through therebetween.
Described seal wire is 2-3 roots, has the guiding groove of guiding seal wire walking, described seal wire diameter in described conduit
d0, guiding groove internal diameter d1Meet equation below with catheter diameter D：
Wherein A is the constant that value is 1~2.5, d in formula0, d1, D unit is millimeter.
Described guiding groove is located at the diverse location of conduit.
Described guiding groove is set in conduit into axial symmetry.
It is a kind of to carry out the method stripped off of vein blood vessel using above-mentioned vein blood vessel stripper, during operation, seal wire is drawn first
Go out, in Endovascular traveling, deliver to great saphenous vein from great saphenous vein initiating terminal and import at femoral vein, then led along seal wire traveling
Pipe, conduit is sent into great saphenous vein trunk tube chamber along seal wire, stripper head end is tightened after seal wire is in place and is fixed on conduit,
Eventually connect blood vessel to strip off out.
When traveling occurs being difficult in the first seal wire, traveling is continued using the second seal wire.
When traveling occurs being difficult in the second seal wire, traveling is continued using the 3rd seal wire.
The present invention is relative to the advantages of prior art：
Using seal wire guiding catheter traveling, the success rate that guiding is stripped off is improved, while more seal wires are located at conduit not
Same position, solve the problems, such as that single wire can not continue guiding after there is flexural deformation, meanwhile, using rational seal wire, lead
Pipe, guiding groove interior diameter relation, had both improved guiding success rate, caused again easy to process.
Brief description of the drawings
Fig. 1 is stripper structural representation of the present invention.
Fig. 2 is stripper longitudinal section of the present invention.
In figure：1 is conduit, and 2 be seal wire, and 3 be round estrade, and 4 be cylinder cap, and 5 be guiding groove.
Embodiment
With reference to embodiment, the present invention will be further described.
A kind of vein blood vessel stripper, including conduit 1, seal wire 2, described conduit 1 for can anti-certain pressure hollow tube,
Seal wire 2 is located in conduit 1 and can walked in conduit 1, and the end connection round estrade 3 of seal wire 2, round estrade 3 is connected by screw thread
Connect cylinder cap 4, the duct for having an insertion among described round estrade 3 and cylinder cap 4, therebetween can by seal wire 2,
Described seal wire is 2-3 roots, and described conduit is interior straight with the guiding groove 5 for guiding seal wire walking, described seal wire
Footpath d0, guiding groove internal diameter d1Meet equation below with catheter diameter D：
Wherein A is the constant that value is 1~2.5, d in formula0, d1, D unit is millimeter.
Because the diameter of seal wire is thinner, and there is certain elasticity and plasticity, thus during traveling, run into blood vessel
Varicose too it is severe can cause insertion it is not smooth when, easily bend the front end of seal wire and be deformed, the seal wire after being deformed without
Method continues to introduce forward, can now use second seal wire to continue traveling forward, the position of the second seal wire in the catheter and first
Seal wire is different, can avoid continuing to deform in identical position, if after second seal wire still deformation occurs, can use the 3rd
Root seal wire continues traveling, and the position of the 3rd seal wire in the catheter is different from first and second seal wire, can avoid going out in identical position
Now deform, guiding groove is arranged in conduit, can be set into axial symmetry, for guiding each seal wire in the different position traveling of conduit.
Wherein, the relative internal diameter size of conduit, seal wire and guiding groove successfully has critical effect for guiding, due to
Seal wire is thinner, if the internal diameter of guiding groove is excessively tiny, frictional force can cause difficulty in walking, and if the internal diameter mistake of guiding groove
Greatly, then seal wire can not be effectively guided, or even is deformed inside guiding groove.The relative internal diameter size of conduit and guiding groove
Also critically important, if conduit is excessive with respect to guiding groove internal diameter, the resistance of traveling is larger in vein, and pain is brought to patient,
, whereas if conduit is too small with respect to guiding groove internal diameter, then it can increase the difficulty of processing.For this, inventor is simulated experiment,
Plastic tube simulated blood vessel using internal diameter close to vein, using toast or pinch rub make its deform after, inside it injection have one
The liquid of viscosity is determined to simulate blood, the stripper of the present invention is imported into simulation practical guide strips off process, by test of many times,
It is found surprisingly that and works as seal wire diameter d0, guiding groove internal diameter d1With the full formula of catheter diameter D：
Wherein A is the constant that value is 1~2.5, d in formula0, d1, D unit is millimeter.
Now, guiding success rate had both been improved, had been caused again easy to process.
Carrying out the method stripped off of vein blood vessel using above-mentioned vein blood vessel stripper is：During operation, seal wire is drawn first,
In Endovascular traveling, deliver to great saphenous vein from great saphenous vein initiating terminal and import at femoral vein, then along seal wire traveling conduit, will
Conduit is sent into great saphenous vein trunk tube chamber along seal wire, and stripper head end is tightened after seal wire is in place and is fixed on conduit, finally
Connect blood vessel together to strip off out.When traveling occurs being difficult in first seal wire, traveling can be continued using second seal wire, when
When traveling occurs being difficult in second seal wire, traveling can be continued using the 3rd seal wire.
