What is a laparoscopic trocar?

Trocar is a versatile medical tool that has usually been inserted into a hollow tube called a cannula, which acts as a portal into the body of a surgical patient. The purpose of Trokar is to introduce three basic elements: lighting, tracking range and surgical tools. The miniaturized modern laparoscopic trocar can accommodate all three or more, as the only piece of surgical equipment.

Although the patent on Trocar was recorded at the beginning of the 19th century, since its original use was primarily to alleviate pressure on built -in fluid or gases, is basically transmitted, if in fundamentally used, in fundamentally use, in fundamentally, basically, in principle, in fundamentally use. A sharply directed pierced device, named for its placed triangular three sides, was first used to view the inner body of the dog in 1905. His help in human surgeInjevauriries.

The first laparoscopic equipment was quite rough compared to modern laparoscopic trocar. The surgeon looked into the direct scattering device made of blurred glass lenses into the dark cover, which barely visible with stray surrounding light. Modern advances in camera and video technology and in fiber optics have taken Laparrscope directly to the surgical destination, where it is illuminated by a cold halogen or xenon light. Electronic technology miniaturized these elements. Miniaturization was also used to design countless surgical tools, such as scissors, windows and staples that can be easily connected or inserted through a laparoscopic trocar.

Trocar itself not only miniaturized, but also proceeded in functional design. They resemble a long metal syringe and are no longer at the tip of the triangular or sharpened. Most of them are equipped with IrrzumavKy and suction tube. The thumb and forefinger controls provide a larger range of manipulation. One of the techniques of laparotomy is to separate the abdominal organs and create a more spacious surgical space by inflating the body cavity with carbon dioxide and laparoscopic trocar was redesigned as a completely sealed tool.

Laparotomy or "open" abdominal surgery is still necessary, but the laparoscopic trocar is increasingly allowing operations to be cut by cutting less than 0.4 inches (1 cm), the diameter of this surgical tool. In the case of surgery of human joints, the cut and the inserted trocar are even smaller. Such laparoscopic operations were thus described as "keyhole" surgery.

In practice, most operations require the use of multiple laparoscopic trocars through several keyhole cuts. Some operating procedures include more than one tool and some tools require two hands handling.
