Safe laparo-endoscopic surgery relies on effective trocar and cannula technology for peritoneal access. This review examines biomechanical principles and techniques to minimize injury during abdominal wall insertion, enhancing surgical safety.

Area of Science:

  • Surgical Technology
  • Minimally Invasive Surgery
  • Biomedical Engineering

Background:

  • Safe access to the peritoneal cavity is crucial for laparo-endoscopic surgery.
  • Trocar and cannula technology significantly impacts the safety and efficiency of surgical access.
  • Understanding biomechanical principles of abdominal wall traversal is key to preventing iatrogenic injuries.

Purpose of the Study:

  • To analyze critical design features of trocars and cannulae for blind insertion.
  • To focus on biomechanical principles governing abdominal wall penetration.
  • To highlight techniques that reduce the risk of injury to vital intra-abdominal structures.

Main Methods:

  • Review of biomechanical principles related to trocar insertion.
