Trocars are placed through the abdomen during laparoscopic surgery. The trocar functions as a portal for the subsequent placement of other instruments, such as graspers, scissors, staplers, etc. Trocars also allow the escape of gas or fluid from organs within the body.
Who uses trocar?
Trocars are used during laparoscopic procedures and other minimally invasive surgery (MIS) to make small, puncturelike incisions in outer tissue layers. These incisions allow surgeons to insert cannulas through which surgical instruments can be introduced.Trocars are used during laparoscopic procedures and other minimally invasive surgeryminimally invasive surgeryThe first laparoscopic procedure was performed by German surgeon Georg Kelling in 1901.https://en.wikipedia.org › wiki › LaparoscopyLaparoscopy - Wikipedia (MIS) to make small, puncturelike incisions in outer tissue layers.

What is the function of trocar and cannula?
Surgical trocar & Cannula are used to perform laparoscopic ('keyhole') surgery. They are used to make a hole on abdomen and to make passage to introduce Telescope and other hand instruments, such as scissors, graspers, etc., Pyramid tip trocars are widely used.
What is a trocar device?
A trocar is a sharp, pointed instrument that provides access into the body. It acts as a passageway for instruments and usually consists of an integrated cannula (a hollow tube).

Whats the difference between a trocar and obturator?
Trocars and obturators fit into the cannulas and are used to introduce the cannula into the joint. Trocars are very sharp and can cause significant cartilage damage; therefore, they should be used with caution. Obturators may be conical or blunt and do not have as much potential for damaging cartilage.
What is a Hasson trocar?
Hasson trocars, the first modern trocars, named after Harrith Hasson, MD, are non-bladed trocars inserted using the open, or direct-cut, method. Direct cut is one of the most common and safest methods of laparoscopic access. The surgeon dissects the tissue layers to ensure safe entry into the abdomen.1 Oct 2009
What are laparoscopic instruments?
Specific surgical instruments used in laparoscopic surgery include obstetrical forceps, scissors, probes, dissectors, hooks, and retractors. Laparoscopic and thoracoscopic surgery belong to the broader field of endoscopy. The first laparoscopic procedure was performed by German surgeon Georg Kelling in 1901.
Where are trocars placed?
Therefore trocars are usually placed in the lower abdomen lateral to the rectus muscle above the ASIS (Fig. 112.6). If an additional trocar is required, it is placed at the level of the umbilicus lateral to the rectus muscle.
What is a trocar procedure?
The trocar technique is a common technique for surgical procedures and interventional placement of tubes and drainage where instruments, tubes or drains are advanced to the target location through a fixed cannula or hollow tube namely the trocar, which acts as a portal in the process.20 Oct 2020
