TROCARS Meaning and
Definition
-
Trocars are a type of medical instrument used in surgery and other medical procedures. These devices consist of a sharp-pointed tube or cannula, equipped with a handle and a mechanism to facilitate insertion into the body.
Trocars are primarily used to create a pathway into body cavities during surgical procedures. They are designed to puncture through layers of tissue, such as the abdominal wall, allowing access to a specific area for visualization or intervention. Trocars are especially useful in minimally invasive surgeries where small incisions are made, as they minimize tissue damage and reduce the risk of infection.
The sharp-pointed tip of a trocar facilitates easy insertion into the body, while the handle allows for controlled placement and manipulation. The cylindrical shape of the device allows for the subsequent insertion of other instruments, such as laparoscopic cameras or surgical instruments.
These instruments come in various sizes and shapes to accommodate different procedures and body types. Some trocars have a blunt tip which is then replaced by a sharp obturator to minimize the risk of injury during insertion. The handle of a trocar usually features a locking mechanism to secure it in place during the procedure, and many modern trocars also include features like a valve to prevent air or fluid leakage.
In summary, trocars are specialized medical instruments used for accessing body cavities during surgeries or other medical procedures. They consist of a sharp-pointed tube or cannula with a handle, designed for controlled insertion and subsequent access for visualization or surgical intervention.
