About the Course:

This module introduces Surgical Technology learners to the trocar and cannula, commonly used access devices in minimally invasive surgery. Learners will explore the individual components, their functions, and how the trocar and cannula assembly provides access for surgical instruments and cameras during minimally invasive procedures. 

Through immersive VR-based interaction, learners will identify the trocar, cannula, stopcock, and valve. They will examine how the sharp trocar creates an opening through the body wall, while the cannula maintains a pathway for instruments and helps support controlled insufflation during procedures such as laparoscopic surgery. 

The module emphasizes instrument recognition, component identification, functional understanding, and the role of the trocar and cannula in supporting minimally invasive surgical access.

Learning Objectives:

  • Identify the trocar and cannula. 
  • Describe the primary function of a trocar. 
  • Explain the purpose of a cannula during minimally invasive procedures. 
  • Explain how the valve helps prevent gas leakage. 
  • Recognize the role of the trocar and cannula in laparoscopic procedures. 
  • Understand how the assembly provides a pathway for surgical instruments and cameras. 
  • Recognize the importance of maintaining appropriate access during minimally invasive surgery. 

This Trocar & Cannula: Components and Surgical Applications training is delivered through our LMS and is available as both web-based and immersive VR training.

At ImmerseLearn, we prepare Surgical Technology learners with foundational knowledge of surgical instruments and devices used in minimally invasive procedures. This module strengthens instrument recognition, component identification, functional understanding, and familiarity with trocar and cannula assemblies through immersive VR-based learning. 

Trocar−
Explore the trocar as a sharp, pointed surgical instrument designed to penetrate the body wall and create an opening for access to a body cavity. Learners will identify the trocar and understand its role in establishing an access pathway during minimally invasive procedures, including laparoscopic and thoracoscopic surgery.
Cannula+
Learn how the cannula functions as a hollow tube that maintains access to a body cavity or tissue during minimally invasive surgery. Learners will understand how the cannula provides a pathway for surgical instruments, cameras, and other devices while remaining positioned during the procedure.
Trocar and Cannula Assembly+
Explore the trocar and cannula as an assembled surgical access device. Learners will understand how the trocar creates the initial opening while the cannula remains in place to provide a controlled pathway for instruments and cameras during minimally invasive procedures.
Stopcock and Valve+
Identify the two important components of the cannula: the stopcock and valve. Learners will understand how the stopcock can control the flow of fluids or gases, including insufflation gas, while the valve provides a seal around inserted instruments and helps prevent gas from escaping during laparoscopic procedures.

By completing this module, learners will develop foundational knowledge of the trocar and cannula and their roles in minimally invasive surgery. Learners will be able to identify the trocar, cannula, stopcock, and valve, describe their basic functions, and recognize how the assembly supports surgical access and instrument passage during laparoscopic and other minimally invasive procedures.
