Description

Technical Field

[0001] The invention relates to the field of instruments with both venous ligation and free stripping functions, in particular to a vascular stripper and a method for using the same. Background Art

[0002] Currently, during varicose vein surgery, high-position ligation and stripping require a larger incision, which causes great trauma to the patient and slows down the patient's recovery. Summary of the invention

[0003] In view of the problems that high-position ligation and stripping in current varicose vein surgery requires a larger incision, causes severe trauma, and leads to slow recovery, the present invention provides a vascular stripper and a method for using the same.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a blood vessel stripper, including a cylindrical handle, a mesh pattern for increasing friction is arranged on the handle, and a flat needle holding part that cooperates with fingers is also arranged to increase the comfort of medical personnel when using it. One end of the instrument is provided with a tapered rod, and the tip is in an arc shape, which can easily enter a small incision to free subcutaneous tissue. A threading hole for threading when closing a blood vessel is also arranged, which can be suitable for subcutaneous closure of diseased blood vessels and epidermal wireless head. The other end is provided with a circular hook with an upward opening, and the circular hook pulls out the vein, strips off the varicose vein, and improves the operation efficiency. The structure is simple, the concept is novel, and the practicability is strong.

[0005] A method for using a blood vessel stripper comprises the following steps: Step 1: When performing high-position ligation of the great saphenous vein without incision, the root of the great saphenous vein is ultrasonically located and 2 mm dot-shaped incisions are made on both sides of the vein with a 11# blade. The stripper with one end of the tapered rod is used to percutaneously enter from one side, pass through the great saphenous vein and exit, and exit from the incision on the other side. The 7# silk thread is passed through the threading hole and brought in. The stripper with thread is withdrawn and one end of the silk thread is brought out of the body surface. The stripper is inserted through the original opening again, passed through the superficial layer of the vein and exited from the opposite exit. The other end of the silk thread is brought in through the threading hole, and the stripper with thread is withdrawn to achieve circular ligation of the great saphenous vein. Step 2: For the superficial protruding veins, cut a 2mm punctate incision with the scissors blade, separate the space around the blood vessels with the end of the stripper with a tapered rod, then replace the end of the stripper with a circular hook to hook out the diseased superficial vein subcutaneously, and use a vascular clamp to clamp and strip it.

[0006] Beneficial effects of the present invention: The vascular stripper and the use method thereof described in the present invention realize minimally invasive high-position ligation and stripping surgery for varicose veins of the lower limbs, reduce trauma, and improve the patient's experience.

[0010] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0011] like Figure 1-Figure 3 As shown, a vascular stripper of the present invention comprises a cylindrical handle 1, both ends of the handle 1 are provided with a needle holding part 3, the ends of the two needle holding parts 3 are respectively provided with a tapered rod 4 and a circular hook 5, a mesh pattern 2 is provided on the handle 1, the mesh pattern 2 can increase friction, so that the friction force when holding is increased, the needle holding part 3 is flat, the flat needle holding part 3 can cooperate with the fingers, so that it is more convenient to hold and improves the comfort when using, the tip of the tapered rod 4 is arc-shaped, it can easily enter the small incision to free the subcutaneous tissue, the end of the tapered rod 4 is penetrated with a threading hole 41, which can be suitable for subcutaneous closure of diseased blood vessels and no wireless head on the epidermis; The total length of the ligature stripper is 183 mm, and the length of the needle holding part 3 plus the tapered rod 4 and the length of the needle holding part 3 plus the circular hook 5 are both 35 mm.

[0012] like Figure 4 and Figure 5 As shown, a method for using a vascular stripper comprises the following steps: The first step is to perform high-position ligation of the great saphenous vein without incision. After ultrasonic positioning of the root of the great saphenous vein, 2 mm dot-shaped incisions are made on both sides of the vein with a 11# blade. One end of the stripper with a tapered rod 4 is used to percutaneously enter from one side, pass through the great saphenous vein and exit, and exit from the incision on the other side. The 7# silk thread is passed through the threading hole 41 and brought in. The stripper with thread is withdrawn and one end of the silk thread is brought out of the body surface. The stripper is again inserted through the original opening, passed through the superficial layer of the vein and exited from the opposite exit. The other end of the silk thread is then brought in through the threading hole 41, and the stripper with thread is withdrawn to achieve circular ligation of the great saphenous vein. Step 2: For the superficial protruding veins, cut a 2mm dot-shaped incision with the scissors blades, separate the space around the blood vessels with one end of the stripper with a tapered rod 4, and then replace the end of the stripper with a circular hook 5 to hook out the diseased superficial vein subcutaneously, and use a vascular clamp to clamp and strip it.

[0013] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
