How Surgical Trocar Needles Reduce Surgical Wounds

A trocar needle is a versatile medical device that is usually inserted into a surgical patient through a hollow tube called a trocar. The trocar needle serves to introduce three essential elements: illumination, endoscopy and surgical tools. The miniaturized modern laparoscopic trocar needle can accommodate three or more as a single surgical device.

Surgical trocar needles are available in different types of disposable and reusable. There are different types of blade surgical trocar needles and non-blade surgical trocar needles with minimal differences.

The blade surgical trocar needle has a spring-loaded locking mechanism that reduces the risk of injury to the internal structure. Due to this product design, it can be safely used with a pneumoperitoneum suitable for abdominal surgery. The blade surgical trocar needle is covered with a sharp linear blade after piercing the abdominal and thoracic cavities, with the blade guard at its tip. Thus, it minimizes tissue trauma that may be caused in intra-abdominal or intrathoracic structures.

The trocar needles themselves are not only miniaturized, but also have an advanced functional design. Like long metal syringes, they are no longer triangular or sharp-tipped: most come with flushing and suction tubes. Thumb and index finger controls offer a wider range of tools to manipulate. One of the techniques of laparotomy is to separate abdominal organs and create a wider surgical space by filling the body cavity with CO2. As a result, the laparoscopic trocar needle has been redesigned as a completely sealed instrument. Increasingly, laparoscopic trocar needles are available for surgery through incisions less than 0.4 inches in diameter with these surgical instruments. In human joint surgery, the trocar needle has a smaller incision and insertion.

In addition, another part of the blade surgical trocar needle product design included is a red blade indicator on the safety indicator above the closed hole. This indicator shows the position of the blade guard relative to the sharp linear blade. Linear sharp blades for disposable surgical trocar needles with blades are typically made of stainless steel. As part of the medical product design, the trocar needle cannula includes an internal seal to prevent gas leakage. As a result, no contamination occurs during insertion or removal of the operating instrument without loss of pneumoperitoneum.

Gas injection and venting are controlled by valves located in the cannula area of the surgical cannula needle with blades. The valve, which is closed except for surgical procedures, becomes open when it is turned parallel to the luer joint. In this way, the product design, blade surgical cannula needle provides medical advantages in the medical field.
