trocars การใช้

In modern times, surgical trocars are used to perform laparoscopic ( keyhole ) surgery.
The Hancock trocars for creating a hole in the left ventricle are rarely used clinically.
Prior to the description of the Seldinger technique, sharp trocars were used to create lumens through which devices could be passed.
Most importantly, it is easy to convert SILS to conventional laparoscopy by adding a few trocars; this conversion to conventional laparoscopy is called'port rescue '.
Special articulating instruments and access ports make it unnecessary to place trocars externally for triangulation, thus allowing the creation of a small, solitary portal of entry into the abdomen.
