What Are Hemostatic Forceps?

Hemostatic forceps are surgical instruments that block blood by clamping blood vessels. Rescue the patient in the case of bleeding. After taking the hemostatic medicine, use a hemostat to clamp the aorta of the blood vessel to prevent the blood from flowing out of the surgical instrument.

Hemostatic forceps are surgical instruments that block blood by clamping blood vessels. Rescue the patient in the case of bleeding. After taking the hemostatic medicine, use a hemostat to clamp the aorta of the blood vessel to prevent the blood from flowing out of the surgical instrument.

The principle of hemostatic forceps is to clamp blood vessels or fur like clips, but it is disinfected. Hemostatic forceps are divided into large, small, toothed, non-toothed, straight and curved. Different types of hemostatic forceps are selected according to different operating parts. The teeth next to the hemostatic forceps handle help keep the hemostatic forceps in place while holding objects and prevent them from falling out.

Hemostatic forceps type

Hemostatic forceps come in a variety of shapes and lengths to suit the needs of different natures of surgery and site. In addition to the common straight and curved types, there are tooth vascular forceps, toothless hemostatic forceps, mosquito-type straight and curved hemostatic forceps, etc. The main difference in structure of hemostatic forceps is the alveolar bed. Cogged beds are divided into straight, curved, right-angle, and curved. When used for hemostasis, the tip should be perpendicular to the tissue, clamp the broken end of the bleeding vessel, and clamp the nearby tissue as little as possible.

1. Injury-free hemostatic forceps: hemostatic forceps mainly used in vascular surgery. The alveolar teeth are thinner, shallower, and have better elasticity. They have a smaller squeezing effect on the tissue and less damage to the vessel wall and intima. The front end of the forceps is smooth, easy to be inserted into the fascia, and difficult to puncture the vein. It can be used to separate anatomical tissues. It can also be used to pull sutures, pull out needles, or substitute forceps. Weak organizations.

2. Curved hemostatic forceps and toothed hemostatic forceps: As shown in Figure 1, the curved hemostatic forceps have a curved tip, which is used to separate and clamp tissues or blood vessels to stop bleeding, and to assist in sutures. It is mainly used for surgical deep tissue or visceral hemostasis. Toothed hemostatic forceps are mainly used for hemostasis of strong tissues, lifting parts of incisions, etc., to clamp blood vessels in thick tissues and easily slipped tissues, such as mesentery, omentum, etc., the front teeth can prevent Slippage, but cannot be used to stop bleeding subcutaneously, and it is not suitable to clamp blood vessels, nerves and other tissues.

3. Straight hemostatic forceps and toothless hemostatic forceps: As shown in Figure 2, it is used for hemostasis of subcutaneous tissue, mainly for superficial hemostasis and tissue separation of the surgical site.

4. Right-angle forceps: as shown in Figure 3, for the guidance of free blood vessels, nerves, ureters, biliary tract and other traction.

5. Mosquito hemostatic forceps: As shown in Figure 4, it is small and suitable for separating small blood vessels and connective tissue around nerves. It is used for hemostasis of small blood vessels, and is not suitable for clamping large or hard tissues. It can easily go deep into the treatment site to grasp items or tissues when the external mouth of the organ or the wound is small, and the hemostatic forceps with elbow can grasp the surrounding tissues on the side.

How to use hemostatic forceps

The correct method of holding the forceps is shown in Figure 5. The thumb and the fourth finger are respectively inserted into the two rings of the hemostatic forceps handle, the middle finger is placed on the hemostatic forceps handle of the fourth ring, and the index finger pressure stabilizes and guides the shaft. Favorable operation. After use, when you release the hemostatic forceps, use your thumb and index finger to hold one ring mouth of the vascular forceps, the middle finger and ring finger to block the other ring mouth, and gently press the thumb and ring finger to the top.

Precautions for using hemostats

1. Hemostatic forceps must not pinch the skin, intestines, etc. to avoid tissue necrosis.

2. Only one or two teeth can be buckled during hemostasis. To check if the buckle fails, sometimes the handle of the forceps will loosen automatically, causing bleeding, so be alert.

3. Before use, check whether the two pages of the horizontal tooth space on the front end are consistent. Those who do not match are not used to prevent the vascular forceps from slipping out of the tissue.

4. During the surgical operation, first clamp the bleeding site or the bleeding point that has been seen. It is required to be accurate when clamping the bleeding point. It is best to succeed at one time. Do not bring too much into the healthy tissue and the thickness of the ligature. To choose according to the amount of tissue clamped and the thickness of the blood vessel, the ligature should be freely ligated separately.

5. When ligating, the tip of the upper vascular forceps must be rotated and raised. The ligating line should completely cover the required ligated tissue. When tightening the first knot, lower the raised vascular forceps and slowly loosen, the first knot is completely When tightening, loosen and remove.

Hemostatic forceps cleaning

After the operation, metal devices such as hemostats used during the operation are more difficult to clean, especially when the blood on the device is dry. Therefore, a piece of gauze with liquid paraffin can be used to wipe bloody metal devices, especially The joints of various instruments and the teeth of various pliers can be gently cleaned with a brush, and finally dried with a clean gauze to sterilize as usual. Liquid paraffin has good oil-soluble properties. Blood stains on metal instruments after surgery are lubricated with liquid paraffin gauze and washed, which is not only easy to clean, but also makes the sterilized metal instruments bright, and joint lubrication is easy to use ^[1] .
