Description
Technical field
This utility model relates to medical instruments field, refers to especially a kind of two-chamber Arterial sheath.
Background technology
In medical science, arterial sheath is to insert in tremulous pulse, for other endovascular treatment material provides the medical apparatus and instruments of path, belongs to intervention consumptive material.Arterial sheath is generally comprised of Arterial sheath, convergent divergent channel, puncture needle and seal wire.During operation, the puncture needle longitudinal axis and skin angle are to 30-45 degree diagonal inserting needle, thrust blood vessel antetheca, blood back groove on puncture needle is shown in blood back, confirm to have stung medium vessels, extract after nook closing member, the trocar sheath of puncture needle is stayed in blood vessel, to trocar sheath interpolation, enter seal wire to Endovascular, insert the seal wire backed off after random trocar sheath of sufficient length, vascular compression point of puncture, Arterial sheath with convergent divergent channel is inserted to blood vessel along seal wire rotation, extract seal wire and convergent divergent channel, Arterial sheath indwelling is in Endovascular, on Arterial sheath, connect a side pipe, heparin-saline is injected in threeway on side pipe, prevent thrombosis in Arterial sheath.
Vascular surgery finds in intervene operation, and being positioned at crotch blood vessel has pathological changes as two blood vessels such as iliac artery crotch, inferior genicular artery crotches, need do kiss technology, two place's blood vessels is carried out to balloon expandable simultaneously.After puncturing successfully, insert Arterial sheath, then through seal wire, insert foley's tube, balloon inflation expansion under the continuous monitoring of fluorescent screen, after expansion finishes, rechecking, the effect of observing expansion.But at present common Arterial sheath is single tract, seal wire enters respectively bifurcated vessels and imports foley's tube to be expanded and belongs to accurate operation, in a tract, operates mutual interference effect, cannot complete smoothly.If got involved and overlap arterial sheaths with two simultaneously, because bifurcated vessels distance is too near, being easy to cause arterial wall to damage even aorta wears out, danger is very high, and severe patient can cause death, and in arterial sheath indwelling and tube drawing process, also can there is certain risk, healing speed is slower, to patient, brings burden mentally and economically, is also unfavorable for save medical resources.
Therefore, need now a kind of Arterial sheath that can make two seal wires or conduit pass through smoothly badly simultaneously.

Adopted after technique scheme, the beneficial effects of the utility model are: in sheath pipe, add a dividing plate, the cavity that sheath base is communicated with sheath pipe is divided into two independent sealed tracts, when doing kiss technology, can be simultaneously by two seal wires or conduit, the lesion vessels at aortic bifurcation place is carried out to balloon angioplasty simultaneously, two ball ductus bursaes import along seal wire rotation in the first tract and the second tract in sheath pipe simultaneously, not interference effect mutually, can complete arrival blood vessels adjacent smoothly.This utility model, by an Arterial puncture intubation, reaches two conduit operating walk ways is provided, and has reduced the risk for the treatment of, has reduced patient's misery, and the Wicresoft that has realized medical care precess, is conducive to save medical resource.
In sheath base, haemostatic valve is installed, haemostatic valve can anti-return blood, avoids that arterial blood is anti-to flow out externally, and facilitates the operation of seal wire and conduit.The both sides of sheath base are equipped with side pipe interface, and the number of side pipe is two, can in art, take a blood sample, pressure monitoring, injection medicament for expanding vascellum or contrast agent.Two side pipes are communicated with respectively the first tract and the second tract, heparin-saline is injected in threeway on two side pipes respectively, can prevent thrombosis in the first tract and the second tract, carrying out after any operation, can clean the first tract and the second tract in sheath pipe by side pipe, in therapeutic process, also can, according to conditions of patients needs, by two lateral canals, inject different medicaments and treat.
On the outer wall of sheath pipe, sign has graduation mark, can in arterial sheath piercing process, allow operator understand the degree of depth in sheath pipe importing patient vessel chamber, graduation mark and scale numeral all incorporate developing agent to be made, and can under X ray, see graduation mark and scale numeral clearly, has facilitated operator's reading.
On sheath pipe, away from one end of sheath base, be provided with end development coating, can under fluorescent screen monitors, show that sheath pipe end, in the position of Endovascular, is conducive to the accurate operation of technology at any time.
The inwall of sheath pipe is provided with inwall development coating, incorporates developing agent in developing layer, the body of sheath pipe is developed under X ray clear, is conducive to Fluoroscopy location.
Sheath base is provided with a dismountable locking device, due in piercing process, convergent divergent channel need to insert in a tract of sheath pipe and stretch out from the opening of sheath pipe, simultaneously along seal wire intravasation chamber, locking device can be fixed convergent divergent channel and sheath pipe, prevent that convergent divergent channel from exiting when sheath pipe enters, sheath pipe itself and tremulous pulse are caused to damage.When behind sheath pipe intravasation chamber, can pull down locking device, extract convergent divergent channel, be conducive to make sheath pipe and convergent divergent channel in the process of entering, can there is not relative sliding, reduce operational risk.
Sheath pipe is triangular in shape away from one end of described sheath base, can make the transition between sheath pipe and convergent divergent channel more level and smooth, natural, makes more successfully intravasation intracavity of sheath pipe.
Threeway is provided with hickey, can connect easily transfusion device, also can do associated treatment by junctor outer circulation pipeline adapter.
