Description

Sengstaken-Blakemore tube type vein stripper and using method thereof

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to a three-cavity two-sac tube type vein stripper and a using method thereof.

Background

Varicose veins are one of the most common clinical vascular diseases, are mostly seen in the great saphenous veins of the lower limbs, and are caused to be circuitous and expanded due to factors such as blood stasis, weak vein walls and the like. At present, a plurality of methods for treating varicose veins exist, but the method of high ligation and exfoliation is the most classical method, and has the advantages of definite curative effect and low recurrence rate. The main trunk of the great saphenous vein needs to be stripped by applying a blood vessel stripper which is generally made of a metal guide wire, in the operation, the near end and the far end of the great saphenous vein are respectively cut and separated from the great saphenous vein, the stripper is inserted into a tube cavity from the far end of the great saphenous vein and is sent to the near end, a stripping head is placed at the far end of the great saphenous vein and is ligated to the great saphenous vein, the great saphenous vein is pushed from the far end to the near end and then is slowly pulled out, and the main trunk of the great saphenous vein is stripped. The two problems that the stripper can not pass smoothly in the operation and the wound surface bleeds after stripping are troubled clinicians, and the fact that one stripper can be invented is very important to solve the two problems.

Disclosure of Invention

The invention provides a three-cavity two-sac tube type vein stripper and a stripping method thereof, which can efficiently and quickly strip veins and reduce bleeding.

The complete technical scheme of the invention is as follows.

The utility model provides a vein stripper, includes three chamber two bag pipes, seal wire, strip the head, three chamber two bag pipes make by natural rubber, the diameter is 3.5mm, there are 3 chambeies in the lumen, 2 of them connect 2 water sacs of front end respectively, 1 chamber both ends are dredged in addition, the seal wire can walk to take shape wherein. The guide wire is made of iron, is positioned in the three-cavity two-sac tube and can walk in the tube, 2 fixing rings are arranged in the center of the guide wire, and the fixing rings are connected with the stripping head through threads.

Firstly, incision is made on the anterior medial malleolus and the medial side of femoral artery, the starting end of the great saphenous vein is cut off, the proximal end is ligated, the great saphenous vein is converged into the femoral vein and cut off, and the distal end is ligated. The guide wire is led out and runs in the blood vessel cavity from the starting end of the great saphenous vein, the guide wire guides the three-cavity two-sac tube to simultaneously run in the blood vessel cavity, the three-cavity two-sac tube is conveyed to the foremost end of the guide wire when the guide wire runs to a tortuous blood vessel and cannot smoothly pass through, the three-cavity two-sac tube is filled with a water sac at the front end to 'straighten' the blood vessel backwards so as to ensure that the blood vessel smoothly passes through, pumping water out of the water sac after passing through the water sac, passing through the water sac by the same method when encountering a tortuous blood vessel again, sending the water sac to the position where the great saphenous vein converges into the femoral vein, pumping the three-cavity two-sac tube backwards out of the blood vessel, screwing and fixing the stripping head on the catheter, fixing the head end of the three-cavity two-sac tube at the rear end of the stripping head, stripping the water sac from the starting end of the great saphenous vein to the position where the great saphenous vein converges into the femoral vein, meanwhile, the three-cavity two-sac tube enters the stripped vein wound surface again, the ice brine is injected to fill the rear water sac, the blood is compressed and stopped, the ice brine is extracted after 15 minutes, the three-cavity two-sac tube is taken out, the incision is sutured, and the whole lower limb is bound by an elastic bandage.

The advantages of the present invention over the prior art are.

The guide wire is adopted to guide the three-cavity two-sac tube to run, the success rate of guiding the peeling is improved, and meanwhile, the three-cavity two-sac tube is used for compression hemostasis after peeling, so that the problems of wound surface and vein branch bleeding after vein peeling are solved.

Detailed Description

The present invention will be further described with reference to the following embodiments.

The utility model provides a three chamber two bag pipe formula vein stripper, includes seal wire (like 1), three chamber two bag pipe (like 2), the seal wire be iron seal wire, two round blunt, about 2400mm long, diameter is about 1mm, there are 2 solid fixed rings (like 11) in the central authorities of seal wire, gu fixed ring peels off head (like 12) through threaded connection, peels off the head diameter and is 10 mm. The three-cavity two-sac tube (as shown in figure 2) is made of natural rubber, is about 1000mm long, has the diameter of 3.5mm, is about 30mm long at the front end, is about 900mm long at the rear end, and is internally provided with 3 cavities (as shown in figure 3), wherein 2 cavities (as 8 and 9) are respectively connected with 2 water sacs at the front end, the other 1 cavity (as 10) is communicated with two ends, and a guide wire can be formed in the cavities (as shown in figure 1). The tail end of the three-cavity two-sac tube is provided with 3 joints (such as 5, 6 and 7), one joint (such as 5) is communicated with the front end water sac (such as 3) through a cavity 8, the front end water sac can be filled by injecting physiological saline by using an injector, the surface of the front end water sac (such as 3) is a frosted surface, and the friction force between the front end water sac and the vessel wall can be increased after filling; one of the joints (such as 7) is communicated with the rear end water sac (such as 4) through the cavity 9, the ice saline can be injected by the injector to fill the rear end water sac, the filled rear end water sac can be used for the purpose of pressing and stanching the wound surface of the blood vessel after denudation, and the ice saline can accelerate the stanching; one of the connectors (e.g., 6) is hollow and can pass a guide wire therethrough and out the front end through the lumen 10.
