Single Port Surgery Access System

A new surgical access system has been designed that is less invasive than current laparoscopic procedures and requires no insufflation of the body and, in many cases, no general anesthesia. The micro-orifice surgical access system has an angular retractor, which is able to enter into a part of the body and flower out to produce a greater area for visualization while holding surrounding tissues and organs in place. Attached to the end is an LED light, which can illuminate the surgical area. The necessary incision is a mere 8 cm, compared to 20 cm in open surgery. The pivoting, angular positioning and locking mechanisms allow for better access with one incision than laparoscopic procedures have with multiple.

Less Invasive than Current Laparoscopic Surgery

The single port surgery access system can be used in minimally invasive surgery and provides improved visualization and manipulation within the body cavity. Current medical procedures use laparoscopic surgery; however, this method requires multiple incisions to get optimal visual and manipulative access to the site. The patient must be under general anesthesia, intubated and insufflated, which can all contribute to complications during surgery. As the medical field moves toward a less intrusive option for surgical procedures, devices which limit the amount of stress on the body during surgery are in demand.

BENEFITS OF THE SINGLE PORT SURGERY ACCESS SYSTEM:

  • Better visualization through retraction, illumination and access
  • Interchangeable lengths for adult, morbidly obese adult and children sizes
  • Smaller and fewer incisions
  • Eliminates the use for carbon dioxide insufflation
