Description
Technical field
A kind of operation dedicated for the lesion vessels of varicose vein patients implementation endarterectomy is the utility model is related to cut
Cutter tool, is especially improved clamping stripping head varication stripper.
Background technology
Varication is common peripheral vascular disease, is common in lower limb great saphenous vein or varix of small saphenous vein, shows as
Superficial veins of lower limb becomes silted up bent in earthworm shape.These usual intravenous valves corrupted, also, not only can not normal blood back, instead
And backflow of blood or local endless loop can be caused, so as to cause blood supply site tissue to tend to necrosis.
In the prior art, treatment varication method is by great saphenous vein root high ligation, to the great saphenous vein of lesion
And the branch vein of varicose implements endarterectomy.
The special apparatus that strips off can be used in common endarterectomy using a stainless steel wire as seal wire, on seal wire medium position
Two stripping heads in cup head cylinder are fixed with, closely or is distally inserted into the limbs great saphenous vein of incision, is cut in the other end
Mouthful export, tightened by slowly pulling in the vein of cup head cylinder stripping head, along different directions pull advance, reach varus or
The outer vein for stripping off lesion.During seal wire implementation, the compliance of stainless steel wire seal wire is poor, and the front end of simple pyramidal profiles is led
It can easily cause insertion not smooth because barrier and the tortuous restriction of wide-angle blood vessel such as venous valve or lesion vessels to head, can not
The lasting propulsion of relatively long distance is repeatedly inserted into export process, and cup head cylinder stripping head is to pass through, it is necessary to repeatedly increase notch
Engagement thread is fixed on seal wire, when needing replacing the cup head cylinder of various outer diameter such as operation, it is necessary to which overall take out is led
Silk, replaces direction of insertion, or screws off stripping head in the middle part of seal wire and replaced, and thus can extend operating time, increase patient's wound
Grieved bitter and patient working strength.

Between, and/or between tail end and adjacent spacing block the spherical crown clamping of clamping various outer diameter can be selected to peel off on demand
Head, wherein, the circle crown head and round platform seat that spherical crown clamping stripping head is connected by mutually axially inlay card are formed, in circle crown head and round platform seat
Axial middle part have a centre bore, the outer wall of circle crown head and round platform seat opens side channel to having respectively between centre bore together.
Especially, the outer end of spirally-guided head end and tail end is round and smooth, and spirally-guided head end is longer than tail end, moreover, spiral lead
It is long pitch auger body between the front-end and back-end of head-end.
Especially, the inner of spirally-guided head end and tail end is connected with a spacing block with plastics seal wire respectively.
Especially, the tip of spirally-guided head end and tail end extends transversely through hole respectively.
Especially, spacing block is in cylindrical shape, and spacing block one end is round and smooth for spherical surface or outer rim chamfering, and the other end is platform
Face, stripping head is clamped for spacing spherical crown.
Especially, in the structure of spherical crown clamping stripping head, the composition surface outer rim ring week position of circle crown head and round platform seat has
Round and smooth chamfering R.
Especially, in the structure of spherical crown clamping stripping head, phase interworking is provided with the composition surface of circle crown head and round platform seat
The positioning spline of conjunction, it can be ensured that engaging is fixed when spherical crown is clamped two sections of side channel rotational offsets on the circle crown head and round platform seat of stripping head
Position.
Especially, centre bore mean inside diameter is slightly less than spacing block outside diameter, and spherical crown can be enable to be clamped stripping head in spacing block
(3) stabilization is blocked on；Round platform seat outer end face is centripetal recessed.
Especially, a spacing block is respectively equipped with close to spirally-guided head end or tail end section on plastics seal wire, plus middle part
A pair of of spacing block, that is, share four spacing blocks, between head end or tail end and spacing block or between a pair of of spacing block at middle part,
It can select to be clamped a spherical crown clamping stripping head on demand respectively.
The advantages of the utility model and effect：Stripping head rotation clamping distribution structure deft design is reasonable, peels off and choose to install replacement
It is convenient, the great saphenous vein of lesion and the branch vein of varicose can be accurately stripped off, overall compliance is good, and easy to implement strip off is worn
OK, the frictional force of section tissue is reduced, easily by vascular lesion position, head is stripped off and will not fall off, reduces operation risk.Operation
Flexibly, highly effective, no vein residual, wound is hidden, and tissue damage is few, mitigates pain and the bleeding time of patient, and wound is small,
Healing time is short, and thorough treatment is uneasy to recur.
