Trocar

The trocar is designed in such a way that its tip can easily penetrate through the skin and tissues, and once inserted, the cannula stays in place to provide continuous access to the surgical site. Trocars are used in various surgeries, especially abdominal, chest, and even gynecological surgeries. Due to their minimal invasiveness and the small incisions they create, they are highly popular and help reduce complications and recovery time after surgery.

Trocars are available in different types and sizes, each with specific applications.

Types of Trocar:

Blade trocars: These trocars have a sharp blade at the tip and are used for quick entry into tissues. They are typically used in initial surgeries that require fast access to body cavities.
Non-blade trocars: These trocars have a blunt tip designed to avoid damage to internal tissues. They are used in precise and delicate surgeries where tissue protection is important.
Automatic trocars: These have a mechanism that automatically places the cannula in position, reducing invasiveness.

Sizes of Trocar: Trocars are usually available in sizes ranging from 3 mm to 15 mm. The size of the trocar is chosen based on the type of surgery and the need to pass different instruments:

3-5 mm: For more delicate procedures and the insertion of smaller instruments.
5-10 mm: The standard size for general surgeries and the insertion of various instruments.
12-15 mm: For passing larger instruments or removing large tissue samples.

The trocar is a key instrument in laparoscopic and minimally invasive surgeries, offering quick and safe access to body cavities with its special design and various types.
