What is the main feature of the VersaStep that reduces damage to tissue?

The main feature of the VersaStep that significantly reduces damage to tissue is the radially expandable sleeve. This design allows the device to create an appropriate working channel without excessively stretching or tearing surrounding tissues. By expanding radially, the sleeve maintains a gentle contact with the tissue, which minimizes trauma and enhances patient safety during procedures.

This feature is particularly important in surgical contexts where precision is crucial, as it provides a more controlled and less invasive approach to accessing the surgical site. In contrast, other components like the bladed trocar involve cutting through tissue, optical visualization helps in guiding the procedure but does not directly protect tissue, and the insufflation needle relates to creating space for operations but does not play a direct role in tissue preservation.
