Video of How to use Laparoscopic Trocar, Graspers and Dissectors
In this educational video, "How to Use Laparoscopic Trocar, Graspers, and Dissectors," we present a step-by-step introduction to three of the most essential instruments in laparoscopic surgery. Whether you are a surgical resident, beginner in minimal access surgery, or a practicing surgeon refining your technique, this video offers valuable insights into the correct handling, positioning, and coordinated use of these instruments for safe and precise tissue management.
Laparoscopic Trocar: Gaining Safe Access
The trocar is the instrument that allows entry into the peritoneal cavity and serves as a conduit for all other laparoscopic tools. The video covers how to select between bladed, bladeless, optical, and threaded trocars, based on the patient's anatomy and procedure type. Key safety steps such as verifying pneumoperitoneum, choosing the proper insertion angle (usually perpendicular or slightly angled depending on site), and checking for internal injury upon entry are thoroughly demonstrated. Proper trocar fixation to prevent slippage and port-site trauma is also addressed.
Laparoscopic Graspers: Tissue Holding Without Trauma
Graspers are used to hold, retract, and manipulate tissues. This video showcases the difference between atraumatic graspers (ideal for delicate structures like bowel, omentum, or uterus) and traumatic graspers (used for firm grip on tissues like the gallbladder or fascia). It explains how to apply the correct amount of pressure and angulation to avoid crushing tissues, and how to use the graspers in coordination with the camera and other instruments to facilitate safe dissection.
3Laparoscopic Dissectors: Precision in Dissection
Dissectors are used to tease apart tissue planes, skeletonize structures, and define anatomy during surgery. The video features common types such as Maryland dissector, hook dissector, and right-angle dissector, demonstrating how to hold them correctly and use both blunt and sharp dissection techniques. The importance of bimanual coordination—where one instrument retracts while the other dissects—is emphasized, along with strategies to reduce thermal spread if energy sources are attached.
Best Practices Highlighted in the Video
Maintain proper instrument alignment through the port axis to avoid torque injury
Use 30° laparoscope angulation to optimize field visualization while maneuvering instruments
Avoid crossing instruments ("sword fighting") to maintain ergonomic efficiency
Combine grasping and dissection strategically to minimize bleeding and tissue trauma
Practice bimanual dexterity to enhance surgical precision and reduce operative time
Applications Across Common Procedures
The coordinated use of trocars, graspers, and dissectors is fundamental in procedures like:
Laparoscopic cholecystectomy
Appendectomy
Hernia repair
TLH and other gynecological surgeries
Diagnostic laparoscopy and adhesiolysis
Conclusion
Mastering the use of laparoscopic trocars, graspers, and dissectors is essential for every surgeon entering the field of minimal access surgery. These instruments form the backbone of nearly every laparoscopic procedure. This video offers not just technique but also the rationale behind safe handling, helping you reduce complications and improve intraoperative efficiency.
