                                The Disposable Veress Needle is used

Pneumoperitoneum needle is a kind of clinical medical device, disposable pneumoperitoneum needle belongs to the second class medical device.

Basic structure:

It is divided into 5 parts, which are needle tube, needle seat, indicating valve, spring and two-way valve.

veress needle (veress needle) needle diameter is generally 2mm, the length of 80mm, 120mm, 150mm and other different specifications, the commonly used size is 120mm and 150mm.

The needle tube consists of a sharp outer needle tube and a blunt needle core. The front end of the needle core is blunt, hollow and has a side hole. It can inject gas, water and suction through the needle core.

How it works:

The pneumoperitoneum needle has a spring protection device. When the abdominal wall is punctured, the needle core retract into the needle sheath when it meets resistance, and the tip of the external needle tube can penetrate the abdominal wall. When the tip punctures the peritoneum and enters the abdominal cavity, the abdominal cavity is filled with carbon dioxide gas and the resistance disappears. However, it should be noted that when there is adhesion in the abdominal cavity, pneumoperitoneum acupuncture will lose its protective effect.

Clinical application:

1. Abdominal chemotherapy with pneumoperitoneum needle.

2. Pneumoperitoneum needle for simple pleural aspiration is simple and convenient, with high success rate and few complications.

3. Laparoscopic high ligation of inguinal hernia sac with suture pneumoperitoneum needle has the advantages of small injury, concealed incision, quick recovery, short hospital stay, simple operation and accurate efficacy. It can also detect contralateral occult hernias, avoiding a second operation.

4. The application of pneumoperitoneum needle threading appendectomy combined with double-hole laparoscopic appendectomy is simple, economical and practical.

Pneumoperitoneum needle function:

It is suitable for puncture the abdominal wall during laparoscopic surgery, and CO2 gas is injected into the abdominal cavity to form the pneumoperitoneum, so as to form the operation space.

Pneumoperitoneum is a key part of the success of laparoscopic surgery. Before the operation, artificial pneumoperitoneum should be established in advance to separate the peritoneal wall from the organs, so that the surgical field of view can be more clearly exposed during the operation, which is conducive to the follow-up doctor's operation.

How to use:

Pneumoperitoneum needle is a needle-like structure, there is a valve behind one end, the gas tube of the carbon dioxide cylinder is connected here when the pneumoperitoneum operation, the tip of the pneumoperitoneum needle is not very sharp, but blunt, which is a very good design, can protect the surgeon or nurse and other people who need to operate.

Although the pneumoperitoneum needle is blunt, when it is used to contact the skin and force down, the needle will pop out to form a piercing needle, so that as long as the contact of the skin and force again, the needle will pop out and slowly Pierce the skin, muscle layer and serous layer, and then reach the abdominal cavity, if you have experience in this operation, you can judge whether to reach the abdominal cavity by feeling.

After reaching the abdominal cavity, it is necessary to stop continuing insertion immediately, because the space and gap of the abdominal cavity are relatively small, continuing insertion will hurt the internal organs, and it is necessary to connect the pneumoperitoneum for ventilation after entering the abdominal cavity

The surgeon or nurse taps the patient's abdomen, and you can see that the abdomen has obvious swelling, and when the swelling reaches a certain degree, you can insert the first Trocar, which is the role of the pneumoperitoneum needle.

What are the common complications of pneumoperitoneum needle puncture?

1. Subcutaneous emphysema: Due to improper location, gas enters the subcutaneous tissue from the abdominal wall and the cannula space.

2. Gas embolism: The pneumoperitoneum needle strayed into the internal abdominal vein, resulting in gas embolism.

3. Respiratory acidosis or hypercapnia: too much pneumoperitoneum pressure carbon dioxide is dispersed and stored in the blood, resulting in respiratory acidosis or hypercapnia.

4, the internal pressure is too high will also pressure the abdominal organs, ischemic damage.

5. Pneumoperitoneum acupuncture through the omentum may cause bleeding or produce interstitial emphysema of the omentum, which is pushed towards the anterior abdominal wall by blowing.

6. Abdominal wall bleeding, causing dilation of blood vessels in the abdominal wall. The source of the bleeding is usually the inferior superior abdominal artery or one of its branches.

7. Major vascular injury may occur when the tip of a tracheal needle or needle tip severs or tears a mesenteric or retroperitoneal blood vessel.

8. Improper placement of pneumoperitoneum needle may lead to intestinal injury, bladder injury, and other trauma conditions. Prevention and control in advance is an important step to reduce injury.
