Description

Carotid shunt

Technical field

The utility model belongs to technical field of medical instruments, and in particular to the neck in being performed the operation for undergoing cervical endarterium denudation is moved Arteries and veins shunt tube.

Background technology

Carotid shunt is a kind of medicine equipment in being performed the operation for undergoing cervical endarterium denudation, and Main Function is in operation In set up bypass, ensure Distal blood flow it is unobstructed on the premise of performed the operation.Current Domestic is shelled for carotid artery intima Carotid shunt in de- art (abbreviation CEA) operation, mostly external import with sacculus shunt tube or the interior turn of tidal stream with spring Pipe, although both shunt tubes can act as substituting temporarily the effect of blood vessel, but, in Clinical practice, with spring Shunt tube quality is partially hard, and the enlargement quality at two ends is partially soft so that it is not easy to be put into Ink vessel transfusing, especially internal carotid one Side；And the sacculus of let it be two ends the have closure of the turn of tidal stream with sacculus, influence the smoothness of tube outer wall, it is not easy to quickly put Enter.Also need to before being put into squeeze into air with syringe, inspection air bag whether gas leakage, more a program.Meanwhile, this two class turns Flow tube all easily causes damage to vascular wall.Additionally, the hospital that CEA operations are carried out at home is relatively fewer, skilled grasp is set up Turn to stay the doctor of technology also few, so, in the market is easy to operate in the urgent need to one, and doctor is easily mastered, and not injured blood vessel A class shunt tube.

The content of the invention

The technical problem that the utility model is solved：A kind of carotid shunt is provided, solves to set up Ink vessel transfusing turn in operation Stream, on the premise of ensureing that Distal blood flow is unobstructed, the blood vessel to blocking carries out inner membrance stripping and repairing operation, reduces the difficulty of operation Degree and risk, reduce the death rate.

Technical solution of the present utility model：Carotid shunt, including the first shunt tube and the second shunt tube, it is described The tube head that first shunt tube and the second shunt tube are hollow straight pipe and opposed end is arc structure, first shunt tube with Second shunt tube junction is vertically connected with extension tube, and the extension pipe end is provided with two-way valve.

Further, first shunt tube with diameter greater than the second shunt tube.

Further, it is provided with graduation mark on first shunt tube and the second turn of tidal stream tube wall.

Further, first shunt tube and the second shunt tube are by gluing connection.

Further, the first shunt tube also transition conduit including connect setting, transition conduit other end connection the Two shunt tubes.

Further, the transition conduit middle part opens up through hole and for connecting extension tube.

1st, the utility model simple structure, low cost, simple header structures can quickly be put into blood vessel during operation, operation Person is easy to grasp and operates with, while also reducing the damage that shunt tube is caused to blood vessel, is conducive to patient's post-operative recovery.

2nd, the utility model production process is simple, using medical grade PVC or silica gel homogenous material, reduces material to people The infringement of body, is easy to Spread in China to produce and use.

3rd, whether the utility model extension tube can both to have observed blood unobstructed in shunt tube, it is also possible in discharging shunt tube Unnecessary air, meanwhile, if needing to place support in patient's art, it is also possible to as seal wire path is guided, support is put into quickly, Shorten operating time, reduce patient suffering.

Brief description of the drawings

Fig. 1 is a kind of structural representation of embodiment of the utility model,

Fig. 2 is the structural representation of the utility model another kind embodiment.

Specific embodiment

1 a kind of embodiment of the present utility model is described below in conjunction with the accompanying drawings.

A kind of carotid shunt, including the first shunt tube 1 and the second shunt tube 2 being sequentially connected with, first turn of tidal stream It is arc structure that the shunt tube 2 of pipe 1 and second is the tube head of hollow straight pipe and opposed end, and simple header structures can during operation To be quickly put into blood vessel, operator is easy to grasp and operates with, and the tube head of arc structure can reduce shunt tube and blood vessel is made Into damage, be conducive to patient's post-operative recovery.The junction of first shunt tube, 1 and second shunt tube 2 is vertically connected with extension Pipe 3, the end of the extension tube 3 is provided with two-way valve 4, and whether extension tube 3 can both observe blood unobstructed in shunt tube, also may be used To discharge unnecessary air in shunt tube, meanwhile, if needing to place support in patient's art, it is also possible under seal wire guide, very It is put into soon, shortens operating time, patient is less by pain.First shunt tube 1 with diameter greater than the second shunt tube 2, Ke Yigeng The thinner blood vessel of the good blood vessel thicker with near-end and distal end coordinates.Set on first shunt tube 1 and the tube wall of the second shunt tube 2 Graduation mark is equipped with, can accurately judge to insert the depth of arteria carotis.The shunt tube 2 of first shunt tube 1 and second passes through gluing company Connect.

In addition, the utility model is made of medical grade PVC or silica gel material, infringement of the material to human body is reduced, be easy to Spread in China is produced and used.

When using, block the corresponding position in artery two ends in neck and place shunt tube, the one end of the first shunt tube 1 is quickly put Enter arteria carotis proximal part, the second shunt tube 2 is quickly put into arteria carotis distal end, and uses noninvasive vessel forceps clamp simultaneously, so as to Control intraoperative hemorrhage, it is ensured that in the case that cerebrum blood is not blocked, the blood vessel to blocking carries out inner membrance stripping and repairing, and passes through Whether the observation blood of extension tube 3 is unobstructed in shunt tube, it is also possible to discharges unnecessary air in shunt tube, meanwhile, if patient Need to place support in art, it is also possible under seal wire guide, be put into quickly, shorten operating time, patient is postoperative to go less by pain Except shunt tube, suture completes operation.

The utility model can according to demand make different specifications and models.

Another embodiment of the present utility model is described with reference to accompanying drawing 2.

A kind of carotid shunt, the first shunt tube 1 also transition conduit 5 including connect setting, the transition conduit 5 is another One end connects the second shunt tube 2, and the middle part of the transition conduit 5 opens up through hole 6 and for connecting extension tube 3.

The present embodiment is connected by transition conduit 5, and more reasonable structure damages smaller after patient's use.Above-described embodiment, simply Preferred embodiment of the present utility model, not for limiting the utility model practical range, therefore it is all will with the utility model right The equivalent variations for asking the content to be done, all should be included within the utility model right.
