Description

Three chamber foley's tubes

Technical field

The present invention relates to intervention area of medical devices, particularly relates to a kind of three chamber foley's tubes.

Background technology

At present, foley's tube is used to intervene operation balloon expandable arteriarctia position, to improve tissue blood supply.Sacculus is led Pipe, near-end steel pipe are made up of medical stainless steel pipe, the end of coaxial dirty pipe, are made up of high density polyethylene (HDPE).Led using sacculus During enlargement of pipe diseased region, foley's tube is first delivered into diseased region, is then pressurizeed and expanded with high pressure resistant sacculus, moved in art in stock After the insertion of vein sheath pipe, intravenous liquaemin, to prevent art medium vessels spasm, before sacculus is withdrawn from, it is sweet to inject nitric acid to Endovascular Oil.

But in interventional procedure, wire catheter can not disposably enter true chamber sometimes, entrance is under inner membrance, Need to break through inner membrance into true chamber, it is necessary to cut or break through false chamber endangium, or the lesion by entirely shutting is, it is necessary to cut Cut by lesion tube chamber, to avoid the repetition of foley's tube from exiting and enter, common foley's tube does not possess this kind of structure.

Therefore, a kind of foley's tube for possessing cutting function in intervention is performed the operation is needed badly now.

The content of the invention

The present invention proposes a kind of three chamber foley's tubes, solves foley's tube in the prior art and does not possess asking for cutting function Topic.

The technical proposal of the invention is realized in this way：A kind of three chamber foley's tubes, including tube head, the near-end of the tube head It is connected with sacculus and three lumens, the outlet of three lumen and handle connects, and the distal end of the sacculus is taper, and the two of the sacculus Lateral boundaries are respectively provided with a developing material tag block, and the near-end of the sacculus is connected with the outer layer of three lumen, and described three The cavity of lumen is by being available for the first cavity that seal wire passes through, being available for the second cavity that medicament injects and the 3rd chamber with vessel knife Road forms, and the distal end of the 3rd cavity is provided with Cun Dao areas, and the vessel knife is arranged in the Cun Dao areas.

As a preferred embodiment, the mid diameter in the Cun Dao areas is less than the opening diameter in the Cun Dao areas.

As a preferred embodiment, the vessel knife is provided with angioscope, and the surface of the vessel knife is provided with one Individual developing material tag block.

As a preferred embodiment, the shoulder of the sacculus, which is provided with, folds sheath.

As a preferred embodiment, first cavity is shaped as D-shaped.

As a preferred embodiment, the outer wall of three lumen is coil type.

As a preferred embodiment, the distal end of the distal end of the sacculus and three lumen is equipped with hydrophilic coating.

After employing above-mentioned technical proposal, the beneficial effects of the invention are as follows：, can in interventional procedure with vessel knife To cut the vascular wall at adjacent lesion position as needed, to avoid the repetition of foley's tube from exiting and puncture.Vessel knife is located at In Cun Dao areas, the mid diameter in Cun Dao areas is less than opening diameter, and vessel knife can be made to be rested in the not used time in Cun Dao areas, used When release, vessel knife is provided with angioscope, is expanded in the case where angioscope is looked at straight, operating personnel can be facilitated to be observed in operation Endovascular situation, the surface of vessel knife are provided with a developing material tag block, can clearly developed under x-ray illumination, really Guarantor is accurately positioned, safe ready.

Sacculus section is small, and catheter propelling is good, can easily pass through lesion, and head end flexibly easily manipulates, and can easily pass through bending Blood vessel.The design of three chambers quickly can fill and empty sacculus, and the folding sheath of sacculus shoulder can make sacculus keep smaller before expansion Diameter, easily by narrow section, enhance the compatibility of sacculus and fold into sheath ability, so as to recover blood flow rapidly, optimize Sacculus fills and emptying time, reduces operation risk.The D-shaped tube chamber design of first cavity, can maintain good pushability and While seal wire tracing property, it is ensured that sacculus fast evacuation, make the expansion and contraction of sacculus more freely.The coil of three lumen outer walls Formula designs, and can effectively be directed to peripheral arterial, enhance flexibility and fold resistance, more easily pass through the crooked position of peripheral arterial, It can ensure that seal wire position is stable when withdrawing.Sacculus and three lumens distal end are covered with hydrophilic coating, are aided with smooth head end transitional technology, The ability for passing through lesion can be improved, reduces operation resistance.
