Area of Science:

  • Surgical instrumentation
  • Minimally invasive surgery
  • Gastrointestinal surgery

Background:

  • Endoscopic surgery requires specialized instruments for organ manipulation.
  • Atraumatic retraction is crucial for patient safety and optimal surgical outcomes.
  • Existing retractors may have limitations in displacing delicate structures like the liver or bowel.

Purpose of the Study:

  • To introduce a novel retractor designed for atraumatic liver retraction.
  • To evaluate the instrument's efficacy in displacing hollow viscera during endoscopic surgery.
  • To assess the clinical performance, ease of deployment, and safety profile of the new retractor.

Main Methods:

  • Design and development of a novel retractor with a silicon-covered uniplanar hook.

Related Experiment Videos

  • Laboratory testing to assess functional capabilities.
  • Clinical evaluation of the retractor in endoscopic surgical procedures.

    • Main Results:

    • The retractor successfully achieved atraumatic retraction of the liver.
    • Effective displacement of hollow viscera from the surgical field was demonstrated.
    • Ease of deployment and atraumatic handling were confirmed in clinical settings.
    • Particular effectiveness was noted for elevating the left lobe of the liver during antireflux surgery.

    Conclusions:

    • The novel retractor provides a safe and effective solution for liver retraction and bowel displacement in endoscopic surgery.
    • The instrument's design facilitates atraumatic manipulation, enhancing patient safety.
    • Clinical use confirms its utility, particularly in complex procedures like antireflux surgery involving the liver.
