Description

Varicose vein closing needle

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to varicose vein closure needle.

Background

Varicose veins refer to varicose veins and dilatation caused by blood stasis, weak vein wall and other factors. The current methods of treating varicose veins are primarily surgical and non-surgical.

The traditional operation therapy is that an incision is made on a varicose vein of a lower leg, and then the lower leg is pulled out, so that a patient feels strong pain, the cost is high, meanwhile, the patient needs hospitalization, and the treatment time is long.

Non-surgical treatments such as laser occlusion, which use laser light to close the main vein, are less effective, especially in veins with varicose veins, and are prone to recurrence; the sclerosing agent injection therapy needs no anesthesia and has low cost, but the sclerosing agent injection has poor treatment effect on the trunk of the great saphenous vein and high recurrence rate.

Therefore, there is a need in the art for a varicose vein occlusion needle that addresses the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The traditional operation therapy in the prior art aims to solve the problems that the pain of a patient is strong, the cost is high, the patient needs hospitalization and the treatment time is long due to the fact that an incision is made in a varicose vein of a lower leg and then the patient is pulled out.

The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The existing traditional operation therapy pointed out based on the background technology is to make an incision on a varicose vein of a lower leg and then draw the varicose vein away, so that the pain of a patient is strong, the cost is high, meanwhile, the patient needs hospitalization, and the treatment time is long. Non-surgical treatments such as laser occlusion, which use laser light to close the main vein, are less effective, especially in veins with varicose veins, and are prone to recurrence; the sclerosing agent injection therapy, need not to anesthesia, the expense is low, but the sclerosing agent injection is poor to the treatment effect of the great saphenous vein trunk, the problem that the recurrence rate is high, the varicose vein closed needle of the utility model, simple in construction, adopt the stainless steel, the integrated into one piece structure, the sleek transition design, there is no dead angle, it is easy to sterilize and clean, the needle point portion adopts the sleek structural design, do not have sharp injury to the soft tissue in operation, only play the effects of blunt peeling off and prizing; meanwhile, the threading hole at the needle tip part is easy to thread and not easy to fall off.

Specifically, as shown in fig. 1 to 3, the utility model provides a varicose blood vessel closing needle, which comprises a needle handle part 1, a needle body part 2 and a needle head part 3; one end of the needle body part 2 is connected with the needle handle part 1, the other end of the needle body part 2 is connected with the needle head part 3, and the needle head part 3 is provided with a threading hole 4. In the present invention, the shape of the needle handle 1 and the shape of the needle body 2 may be the same or different, for example, the needle handle 1 may be a rectangular strip, the needle body 2 may be a cylindrical structure, and the change of the needle handle 1 and the needle body 2 by the skilled in the art should be limited within the protection scope of the present invention. The threading hole 4 can be a long round hole, an elliptical hole or a round hole, and the change of the shape of the threading hole 4 by the technicians in the field is limited within the protection scope of the utility model.

Preferably, as shown in fig. 1 to 3, the threading hole 4 is shaped as an oblong hole, so that threading is easy and the threading is not easy to fall off after threading.

Preferably, the oblong hole has a length of 3.5 mm and a width of 1.5 mm.

Preferably, as shown in fig. 1 to 3, the needle handle 1, the needle body 2 and the needle head 3 are an integral structure, and the joints of the needle body 2, the needle handle 1 and the needle head 3 are all designed in a smooth transition manner, so that dead corners are avoided, and the needle is convenient to clean and sterilize.

Preferably, as shown in fig. 1 to 3, the needle portion 3 has a flat structure with a radian, and the thickness of the needle portion 3 is gradually reduced, that is, the thickness of the junction between the needle portion 3 and the needle body 2 is the largest, the thickness of the needle tip of the needle portion 3 is the smallest, and the needle tip of the needle portion 3 has a rounded structure, so that the needle does not cause sharp damage to soft tissues in operation, and only plays roles of blunt dissection and prying. Because the needle point hardness in the existing design is not enough, causes the risk of bending or rupture easily, so the utility model discloses a closed needle's syringe needle portion 3's width is greater than the diameter of needle body portion 2, and the shape of needle body portion 2 is cylindrical.

Preferably, the tip segment 3 is rectangular in plan development.

Preferably, as shown in fig. 1 to 3, the angle between the needle portion 3 and the extension line of the needle body portion 2 in the longitudinal direction is 35 °.

Preferably, as shown in fig. 4, one of the two gripping surfaces of the needle shaft is provided with an anti-slip thread which, on the one hand, can play an anti-slip role and, on the other hand, can let the user know whether the gripped closing needle is on the front or on the back.

Preferably, the needle handle 1 has a length of 80 mm and the needle body 2 has a length of 75 mm.

The utility model discloses a concrete operation of closed needle is as follows:

two incisions of about 3 to 4 millimeters are respectively arranged at the two sides of the varicose vein, and the needle head part 3 of the closed needle enters from the incision at one side; the thread hole 4 of the closed needle is threaded with a polymer thread which is respectively threaded through the lower end and the upper end of the varicose vein. Then closing the varicose blood vessel by using a macromolecule line, and stripping and loosening the soft tissue adhesion part around the varicose blood vessel. The whole operation process has small wound, small wound and small damage to soft tissues, and achieves the perfect closing purpose.
