[0001] SURGICAL VOLUME CLIPS AND VASCULAR CLIP APPARATUS USING THE SAME [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a surgical vascular clip used for cutting or hemostasis of a blood vessel during surgical operation, and a vascular clip applier using the same.

During surgical operations such as organ resection, procedures for cutting or hemostasis of veins or arteries are frequent. Particularly, in order to prevent excessive bleeding when the blood vessels are cut, both sides of the blood vessel to be cut are subjected to hemostasis prior to cutting the blood vessels.

Generally, hemostasis of blood vessels consists of suturing or ligation of blood vessels using surgical threads. However, since hemostasis of the blood vessel using the surgical thread is required to manually suture or ligature the blood vessel using a needle and a suture material, it takes a lot of time in limited space and limited operation such as endoscopic surgery, There is a problem that it is difficult to perform. In addition, there is always the possibility of vascular laxation or loosening due to loosening or slipping of the ligation thread during the ligation of the vascular lumen with the use of a surgical thread, which is more likely to occur with larger vessels and can cause serious problems of postoperative bleeding .

Meanwhile, surgical bleeding clips have been proposed and widely used to solve the problems caused by using the surgical thread. Such a hemostatic clip for surgical use can be applied relatively easily and quickly as compared with a method using a surgical thread, and the frequency of use thereof is increasing not only in open surgery but also in endoscopic surgery.

There is a technique such as the above-described conventional hemostatic clip for surgical use, which is disclosed in Korean Patent Laid-Open No. 10-2010-0033850, entitled " Surgical hemostatic clip ", but this technique forms a protrusion in the inside, And it is difficult to find a proper compression point, so that excessive vascular damage due to excessive compression may occur. On the other hand, when the blood vessel is loosely squeezed to avoid excessive compression, there may arise a problem that the blood clipping clip is released during the vascular pulse.

Hereinafter, a surgical vascular clip according to the present invention will be described in detail with reference to FIGS. 1 to 10 and embodiments.

First, the surgical clip 100 refers to a hemostatic clip used for hemostasis of both sides of a blood vessel to be cut before cutting the blood vessel in order to prevent excessive bleeding when the blood vessel is cut in surgical operation.

1 and 3, a surgical vascular clip 100 according to the present invention includes a leg member 110, a pin member 120, and a hemostatic member 130. As shown in FIG.

More specifically, the surgical vascular clip 100 according to the present invention places a blood vessel between a pair of legs opposed to each other and connected to each other during surgical operation, compresses the pair of legs to press the blood vessel, .

In the present invention, one leg of the pair of legs is referred to as a first leg 111, and the other leg is referred to as a second leg 112.

The first leg 111 and the second leg 112 may be in the shape of a 'U' shape which is opposed to each other when they are applied to a surgical site, and one side is closed to be connected at the connection and the other side is opened.

At this time, the first leg 111 is located on one side of the bleeding part and presses the corresponding part, and the second leg 112 is located on the other side of the bleeding part and can press the corresponding part.

As a specific aspect, the surgical vascular clip 100 may be formed of a commonly used material, and may be formed of, for example, a biocompatible metal material such as stainless steel, titanium, or synthetic resin. Such materials are non-toxic and should be tolerant to the body during the required period. In addition, the leg member 110 may be made of any metal that is harmless to the human body, and may be a material whose shape is not changed by force when deformation occurs.

In addition, the surgical vascular clip 100 according to the present invention includes pins formed to protrude from the inner surface of the leg member 110 contacting the blood vessel 10, so that when the leg member 110 is pressed, 10) to fix the blood vessel 10.

The pin formed to protrude from the inner surface of the first leg 111 is referred to as a first pin member 121 and the pin formed to protrude from the inner surface of the second leg 112 is referred to as a second pin member 122.

At this time, the first pin member 121 and the second pin member 122 may include at least one of the first pin member 121 and the second pin member 122, 111 and the second legs 112. In this case,

When the first pin member 121 and the second pin member 122 are engaged with the blood vessel 10, the first pin member 121 and the second pin member 122 are provided at positions staggered from each other and are formed to abut against the inner surface of the opposite leg when compressed . Since the surgical blood vessel clip 100 is coupled with the blood vessel 10 by the pin member 120, even if the gap is relatively large due to loose compression, stable coagulation can be maintained and the binding force can be effectively maintained. In addition, since the first pin member 121 and the second pin member 122 are formed to abut the inner surface of the opposite side legs, excessive compression is not caused, and even if a relatively large gap is generated, The bonding force can be maintained at a high level.

Meanwhile, the surgical vascular clip 100 of the present invention can be variously manufactured according to the size of the blood vessel 10 to be hemostasis. For example, the length of the leg member 110 may be 8 to 30 mm, and the length of the pin member 120 may be 1 to 3 mm. At this time, when the length of the leg member 110 is less than 8 mm, the size of the surgical vascular clip 100 is small, which is difficult to manufacture. When the length exceeds 30 mm, .

Particularly, the leg member 110 may have an outer diameter of 3.14 / (2 + 1 to 2) mm, and the length of the pin member 120 may vary depending on the type of the blood vessel 10.

More specifically, the length of the pin member 120 may vary due to differences in the thickness of the veins 10 of the arteries and the veins. For example, when applied to a blood vessel 10 having an outer diameter of 10 mm, the length of the leg member 110 may be 17 to 18 mm, and the length of the pin may be 2 mm when applied to an artery, . In addition, when applied to a blood vessel 10 having an outer diameter of 5 mm, the length of the leg member 110 may be 9 to 10 mm, and the length of the pin may be 1.5 mm when applied to an artery and 1 mm when applied to a vein have.
