Disposable Optical Trocar

Disposable Optical Trocar

An optical trocar is a specialized surgical instrument used in minimally invasive procedures, particularly in laparoscopic surgeries, to create an entry point into the abdominal cavity. The unique feature of an optical trocar is its incorporation of an optical system that allows for direct visualization during the insertion process, enhancing safety and precision.

Components and Design

  1. Cannula: The hollow tube that remains in place once the trocar is inserted. It provides a pathway for surgical instruments.
  2. Obturator: The sharp or blunt insert used to penetrate the abdominal wall. In an optical trocar, the obturator is designed to accommodate an endoscope or laparoscope.
  3. Endoscope/Laparoscope Port: A built-in port that allows for the insertion of an endoscope or laparoscope to visualize the entry process.
  4. Seal and Valve System: Ensures that the insufflation gas (typically CO₂) does not escape, maintaining the pneumoperitoneum.

Advantages of Optical Trocars

  1. Direct Visualization: The integrated optical system allows surgeons to see the layers of the abdominal wall and the entry process in real-time, reducing the risk of injury to internal organs and blood vessels.
  2. Enhanced Safety: By providing visual guidance, the optical trocar helps avoid complications such as bowel or vascular injury.
  3. Precision: Facilitates accurate placement of the trocar, improving the overall efficiency and effectiveness of the procedure.
  4. Reduced Blind Entry: Unlike traditional trocars that require a blind insertion, optical trocars minimize the risk associated with blind entry.


  • Laparoscopic Surgery: Commonly used in procedures such as cholecystectomy, appendectomy, hernia repair, gynecologic surgeries, and bariatric surgery.
  • Initial Entry: Often used for the initial entry into the abdominal cavity to establish pneumoperitoneum and insert additional ports.
  • Re-entry: Can be used when multiple entries are required during a procedure, providing continued visualization for safety.


  1. Preparation: The patient’s abdomen is insufflated with CO₂ to create a working space.
  2. Insertion: The optical trocar, with the endoscope or laparoscope inserted, is gently advanced through the abdominal wall under direct visualization.
  3. Placement: Once the trocar has penetrated the abdominal wall, the obturator is removed, leaving the cannula in place for instrument access.
  4. Use: The surgical instruments are introduced through the cannula, and the procedure is performed under laparoscopic guidance.

Types and Variations

  • Disposable vs. Reusable: Disposable optical trocars are designed for single use to ensure sterility and prevent cross-contamination. Reusable trocars can be sterilized and used for multiple procedures.
  • Sizes: Available in various diameters (commonly 5mm, 10mm, 12mm, etc.) to accommodate different surgical instruments and procedures.
  • Blunt vs. Sharp Tips: Some optical trocars have blunt tips for safer entry, while others have sharp tips for easier penetration of the abdominal wall.

Examples of Procedures Using Optical Trocars

  • Laparoscopic Cholecystectomy: Removal of the gallbladder.
  • Laparoscopic Appendectomy: Removal of the appendix.
  • Laparoscopic Hernia Repair: Repair of abdominal hernias.
  • Gynecologic Surgeries: Procedures such as hysterectomy or oophorectomy.
  • Bariatric Surgery: Weight-loss surgeries like gastric bypass or sleeve gastrectomy.

Overall, optical trocars are valuable tools in laparoscopic surgery, providing enhanced safety, precision, and efficiency by allowing for direct visualization during the insertion process.

removed at the end of the procedure, and the incisions are closed.


After the procedure, the disposable trocar is safely discarded according to medical waste disposal protocols to prevent any risk of contamination or infection.

Using disposable laparoscopic trocars has become standard practice in many surgical settings due to their convenience, safety, and efficiency in minimizing infection risks.
