Description
Technical field
The invention belongs to medical instruments fields, more particularly, to a kind of Sengstaken-Blakemore tube formula vein denudation device and its user
Method.
Background technology
Varication is one of vascular diseases most commonly seen in clinic, is more common in lower limb great saphenous vein, since blood becomes silted up
The factors such as stagnant, vein tube wall weakness, cause vein it is tortuous, expansion.There are many cirsoid therapies at present, but a high position is tied
Prick, the method for endarterectomy is a kind of most classical method, with the low advantage of curative for effect, recurrence rate.To great saphenous vein master
Dry stripping off needs that blood vessel stripping device, generally wire guide is applied to be made, during surgery, each work in great saphenous vein proximal end and distal end
Stripper is inserted into tube chamber from great saphenous vein distal end and sent to proximal end by notch and detachment great saphenous vein, is placed in great saphenous vein distal end
It strips off head and ligatures great saphenous vein, then slowly pulled out by distally proximally promoting, strip off entire great saphenous vein trunk, this side
Method, which is often effectively caused since blood vessel is tortuous, to be inserted into unsmooth, can not be successfully stripper from distally sending to proximal end, so that midway needs
Increase notch, while stripping off rear great saphenous vein surface of a wound meeting bleeding, it is postoperative to cause subcutaneously to become silted up green and increase patient's pain.In art
Stripper can not be successfully by with strip off rear surface of a wound bleeding both of these problems and annoying clinician always, a kind of stripping can be invented
De- device solves both of these problems simultaneously to be particularly important.
Invention content
The present invention provides a kind of Sengstaken-Blakemore tube formula vein blood vessel stripper and its method of exfoliation, can efficiently, quickly
Vein blood vessel is carried out to strip off and reduce bleeding.
The complete technical solution of the present invention is.
A kind of vein blood vessel stripper, including Sengstaken-Blakemore tube, seal wire, head is stripped off, the Sengstaken-Blakemore tube is by natural
Rubber is made, a diameter of 3.5mm, there is 3 chambers in tube chamber, wherein 22 water pockets that respectively connected front end, other 1 chamber two
End is come round, and seal wire can be out of shape in wherein.Seal wire is iron seal wire, and can be in walking in pipe, seal wire in Sengstaken-Blakemore tube
Center have 2 fixed rings, fixed ring, which is connected through a screw thread, strips off head.
It takes before internal malleolus and femoral artery inner incision, great saphenous vein initiating terminal is cut off, proximal end ligation, by great saphenous vein first
It imports at femoral vein and cuts off, distal end ligatures.Seal wire is drawn, from the traveling of great saphenous vein initiating terminal in Endovascular, seal wire guiding
Sengstaken-Blakemore tube traveling simultaneously in Endovascular, traveling to tortuous blood vessel can not be successfully by when Sengstaken-Blakemore tube sent to seal wire
Front end, Sengstaken-Blakemore tube, which fills front end water pocket and " stretches " blood vessel backward, makes it pass through, by the water in rear extraction water pocket, if
Pass through with method when meeting tortuous blood vessel again, send to great saphenous vein and import at femoral vein, extract Sengstaken-Blakemore tube out blood vessel backward,
It is fixed on conduit stripping off head and tightening, Sengstaken-Blakemore tube head end, which is fixed on, strips off a rear end, from great saphenous vein initiating terminal to big
Saphena is imported at femoral vein and is stripped off, while Sengstaken-Blakemore tube is again introduced into and strips off the vein surface of a wound, and injection brine ice is full
Rear end water pocket, hemostasis by compression extract brine ice out and take out Sengstaken-Blakemore tube, sew up the incision, entire lower limb are taut with elastic force after 15 minutes
Band wrapping.
The present invention compared with the existing technology the advantages of be.
Sengstaken-Blakemore tube traveling is guided using seal wire, improves the success rate that guiding is stripped off, while three chambers are applied after stripping off
Two capsule pipe hemostasiss by compression solve the problems, such as the surface of a wound and venous tributary bleeding after vein stripping.

Specific implementation mode
The present invention will be further described With reference to embodiment.
A kind of Sengstaken-Blakemore tube formula vein blood vessel stripper, including seal wire（Such as 1）, Sengstaken-Blakemore tube（Such as 2）, described leads
Silk is iron seal wire, and both ends round blunt is about 2400mm, and there are 2 fixed rings in the center of diameter about 1mm, seal wire（Such as 11）, fixed ring
It is connected through a screw thread and strips off head（Such as 12）, strip off an a diameter of 10mm.The Sengstaken-Blakemore tube（Such as Fig. 2）By natural rubber system
At being about 1000mm, a diameter of 3.5mm, front end water pocket is about 30mm, and rear end water pocket is about 900mm, there is 3 chambers in tube chamber（Such as
Fig. 3）, wherein 2 chambers（Such as 8,9）2 water pockets of front end are respectively connected, in addition 1 chamber（Such as 10）Both ends communicate, and seal wire can be walked
Shape is in wherein（Such as Fig. 1）.There are 3 connectors in the end of Sengstaken-Blakemore tube（Such as 5,6,7）, one of connector（Such as 5）Transit chamber 8 with
Front end water pocket（Such as 3）It communicates, can be filled front end water pocket with syringe saline injection, front end water pocket（Such as 3）Surface is mill
Sand face can increase the frictional force of itself and vascular wall after full；One of connector（Such as 7）Transit chamber 9 and rear end water pocket（Such as 4）Phase
It is logical, brine ice can be injected with syringe and fill rear end water pocket, full rear end water pocket can stop stripping off the blood vessel surface of a wound and rising to oppress
The purpose of blood, brine ice more accelerate its hemostasis；One of connector（Such as 6）Hollow, the interior seal wire that is passed to passes through chamber 10 from front end
It is pierced by.
It takes before internal malleolus and femoral artery inner incision, great saphenous vein initiating terminal is cut off, proximal end ligation, by great saphenous vein first
It imports at femoral vein and cuts off, distal end ligatures.Seal wire is drawn, from the traveling of great saphenous vein initiating terminal in Endovascular, seal wire guiding
Sengstaken-Blakemore tube traveling simultaneously is in Endovascular（Such as Fig. 5）.Seal wire traveling to tortuous blood vessel can not be successfully by when, by three chambers two
Capsule pipe is sent to seal wire front end, with syringe from 5 saline injection of connector, Sengstaken-Blakemore tube front end water pocket is filled to light and is drawn
When conduit can not smoothly pull out it, it was demonstrated that water pocket has certain frictional force with vascular wall, and it is same then slowly " to stretch " blood vessel backward
When transport seal wire so that it is passed through tortuous blood vessel（Such as Fig. 6）, make front end from the extraction physiological saline of connector 5 with syringe by rear
Water pocket " disappearance " passes through seal wire using same procedure if meeting tortuous blood vessel again.Seal wire send to great saphenous vein and imports
To be pierced by femoral vein, Sengstaken-Blakemore tube extraction blood vessel is exposed into fixed ring backward, is fixed on conduit stripping off head and tightening,
The ligation of Sengstaken-Blakemore tube head end, which is fixed on, strips off a rear end, imports at femoral vein and carries out from great saphenous vein initiating terminal to great saphenous vein
It strips off, while Sengstaken-Blakemore tube is again introduced into and strips off the vein surface of a wound, rear end water pocket by chance at surface of a wound position, passes through 7 note of connector
Enter brine ice fill rear end water pocket, by Sengstaken-Blakemore tube rear end water pocket fill to light pull catheter can not by its smoothly pull out when, protect
Hold 15 minutes, hemostasis by compression, after with syringe from connector 7 extract out brine make rear end water pocket " disappearances " extract out Sengstaken-Blakemore tube, stitch
Notch is closed, entire lower limb are wrapped up with Elastic bandage.
