Trocars are medical instruments used to create access points in the body for the introduction of other surgical instruments during laparoscopic or endoscopic procedures.
They typically consist of a pointed end (to facilitate entry through the tissue), a cannula (a tube that maintains access to the surgical site), and sometimes a valve system to control gas flow.
The term "multi-function" suggests that the trocar you are referring to may have additional features or capabilities beyond the basic design. These additional features could include things like specialized tips, adjustable lengths, integrated irrigation and suction, or other functionalities to enhance the versatility of the trocar during surgery.
