Hemoclips and their use

One of the most common complications in surgery is bleeding. The surgical team is always looking for ways to reduce bleeding during surgery to prevent complications from internal bleeding in the patient’s body. But in some conditions and surgical situations, there is a possibility of tearing and cutting the vein and eventually internal bleeding, and a way must be found to prevent bleeding. One of these ways to control bleeding in surgery is the use of a vascular clip or hemoclip.

Vascular clips are clips used to close small blood vessels during surgery. These clips can be placed in any part of the surgical site that needs to close the vessels. these clips do not interfere with the function of the organs and unlike some adhesives and thermal tools, they do not damage the tissue.

In the following, we will get to know more about this product and explain the different models available and the basic principles of its use and benefits.

What is hemoclip?

Hemoclip made of metal and polymer are used to close blood vessels (veins and vessels) during open or laparoscopic surgery with the aim of controlling bleeding and also determining the location of body structures in radiographic procedures.

Implantable hemoclips are mainly used to stop bleeding and are pick up by an applier (special tool).

Early-designed clips were large, awkward, cumbersome, and difficult to use. And due to frequent mistakes and technical problems in placing the clip during surgery and many complications, it was not welcomed by surgeons at first. However, with the improvement in the design of the next versions and the correction of the said items, their quick use; It spread first in Japan and then in Europe.

The use of hemoclip

These clips are used in open and laparoscopic surgeries to prevent bleeding in the gastrointestinal tract, to close pulmonary vessels, and also in surgeries such as gallbladder surgery, appendix surgery, uterine hysterectomy, oophorectomy, etc.

Obviously, high blood flow causes the hemoclip to slip and open, as a result, this device is not used to close large vessels. In such cases, other methods are usually used, such as using thread and sewing the vein. Also, cautery is used in capillaries and smaller veins that are controlled by burning, and tampons are used for unspecified scattered bleeding.

It should be noted that in the use of hemoclips, two or more hemoclips are used to increase safety in the path of larger vessels.

Types of hemolock clips:

Asia Jarah Pishro company produces hemoclips made of polymer in different sizes, each of these clips is selected for a specific diameter of the vessel based on the knowledge and discretion of the surgeon.

One of the positive features of the product is its optimal design, which fully considers safety and performance.

How to use Hemoclip

After finding the bleeding point, the clip is removed from the base using an applier of a size appropriate to the color of the clip.

The clip is closed and fixed on the damaged vessel in the desired direction using an applier. When the hemoclip is properly placed, it stays in place without additional movement. This is done for both sides of the veins to close both the blood flow and its return. Usually, 2 clips are installed on the blood flow side to ensure functionality.

Notes on the applier (hemoclip accessory)

Appliers are precise surgical instruments and are used to apply staples. Optimal performance depends on the performance of the applier. Service and adjustment of clip appliers should be done regularly. All clip-compatible appliers, regardless of age and manufacturer, must be repaired, modified, or replaced with new appliers.

Advantages of using AJP brand clips

• The grooves on the clips make them easily fixed on the vessels.
• Polymer hemoclips are non-absorbable and non-conductive. On the other hand, they pass X-rays, etc., so there will be no interference with MRI, CT, and X-rays.
• The materials used in making these clips do not rust or rot over time, and these clips are used in sensitive parts of the body such as the brain, heart, joints, lungs, etc.
• To block the veins, their shape is such that it is placed on both sides of the applier, and by using the applier, it starts to bend from the middle, and finally, the two edges of the clip are compressed and connected to each other.
• The curved shape of these clips makes it cover a large area of ​​the vessel or hollow organ of the body.
• The ability to bend makes it easy to change shape and there is no risk of the vessel falling off or being damaged when occluded because it is fixed in place by its structure.
