The VersaStep™ bladeless trocar system includes a radially expandable sleeve for smaller post-operative fascial defects than with standard bladed trocars.1 Using VersaStep™ trocars reduces the need for fascial closure, as well as the potential for trocar-site hernias.2
In a bariatric clinical trial, the radially expanding VersaStep™ trocars resulted in:2
VersaStep™ bladeless trocar system is not a sharp cutting trocar
A conventional trocar:
With VersaStep™ bladeless trocar system, the initial needle tract is radially expanded so tissues are stretched, not cut. This leads to:
VersaStep™ bladeless trocar system is self-anchoring
Conventional trocars frequently become dislodged, resulting in:
With the VersaStep™ bladeless trocar system, radially expanding dilation stretches and compresses the tissue, fixing the cannula securely to the abdominal wall. This selfanchoring feature virtually eliminates the likelihood of port displacement and re-entry with another sharp device. Slippage rarely, if ever, occurs.
In addition, the VersaStep™ Plus single-use seal minimises the likelihood of tears and leakages, and provides hands-free instrument exchange from 4.5 mm to 12 mm without external converters.
VersaStep™ Plus instruments are available in:
VersaStep™ trocars significantly reduce the need for post-operative analgesia and help patients return to a normal lifestyle quicker than they would with conventional cutting trocars6
