Cannula

A cannula is a hollow tube for introducing liquids or gases into hollow organs of the body. It consists of two main parts: a cannula and a trocar. A trocar is a solid rod that facilitates insertion of a cannula into the cavity. Once the cannula is inside, the trocar is removed, leaving only the cannula for further procedures.

A cannula is used to introduce various substances into the body, such as medications, nutritional solutions, or gases. It can be used to treat various diseases, such as bladder or vascular diseases.

One of the advantages of using cannulas is their safety. They do not cause complications and do not require a long time to install. In addition, the cannulas can be easily removed after the procedure.

However, like any other medical instrument, the cannula can cause some complications such as infections, bleeding or tissue damage. Therefore, before using the cannula, it is necessary to carry out thorough preparation and follow all safety rules.

Overall, a cannula is an effective tool for administering drugs and other substances into hollow organs of the body. It has a number of advantages over other methods of administration, but requires careful preparation and compliance with safety rules when used.

Cannulas are used in various fields of medicine, especially surgery and urinary tract medicine. These are hollow tubes that can come in various sizes and shapes. In the case of heart surgery, for example, cannulas made of plastic or metal are used, which allows them to be securely held in the cavity of the heart. When it comes to bladder surgery, cannulas are used to remove stones. These cannula tubes have trocars that anchor them into blood vessels or the bladder. Cannula tubes are always reusable and can be used several times in one operation. They allow not only to remove stones, but also to install catheters for temporary storage of urine.

A cannula is a device for injecting liquid or air into body cavities. It is a thin flexible tube made of silicone or latex. Cannulas vary in tube diameter, which is reflected in their name. Typically, the tube is heated to reduce the risk of blood clots and slippage of the channel in the vessel. It is shaped like a long flexible tube-like catheter, similar to a surgical instrument. It is used for drainage of the pleural cavity, abdominal cavity, anesthesia (a cannula is necessary if it is necessary to increase the volume of injected gas - for example, during inhalation anesthesia), in cosmetology, physiotherapy, gastroenterology, endocrinology, vascular surgery, gynecology, otorhinolaryngology, oncology, eye surgery and other areas of medicine. Sometimes, when taking blood from a finger, an intravenous drip - a cannula - is used instead of a needle.
