Radially expanding access

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

  • A 0% hernia incidence rate 
  • Reduced operative time and expenses compared with bladed trocars, because a closure was not required after trocar removal 

VersaStep™ bladeless trocar system is not a sharp cutting trocar 

A conventional trocar: 

  • Can cut or tear tissue3 
  • Requires substantial force to penetrate the abdominal wall,which can cause: 
    • Tenting of abdominal wall tissue3 
    • Severing of blood vessels3 
    • Displacement/disruption of the tissue and incisional tissue trauma3

With VersaStep™ bladeless trocar system, the initial needle tract is radially expanded so tissues are stretched, not cut. This leads to:  

  • Effective tamponade of blood vessels 
  • Reduced incisional bleeding1,4 
  • Decreased incidence of bowel, bladder and major vascular injuries 
  • Slit-like wounds that are approximately half the size of those created by comparably sized trocars1 
  • Reduced post-operative wound pain5 and incisional hernias2 
  • Reduced procedure time2,5

VersaStep™ bladeless trocar system is self-anchoring 

Conventional trocars frequently become dislodged, resulting in: 

  • Pneumoperitoneum loss 
  • Repositioning – requiring re-entry of a sharp trocar and reinsufflation of the abdomen 
  • Increased procedural times 

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: 

  • Diameters: 5 mm, 11 mm, 12 mm and 15 mm 
  • Cannula lengths: 70 mm, 100 mm and 150 mm
