A Postural Mechatronic Assistant Trainer (PMAT) aids solo pediatric Nissen surgery. This robotic system enhances autonomous optic handling and logistical planning for surgeons.

Area of Science:

  • Surgical Technology
  • Robotics in Medicine
  • Pediatric Surgery

Background:

  • Nissen fundoplication is a common surgical procedure for gastroesophageal reflux disease.
  • Minimally invasive techniques have become standard in pediatric surgery.
  • Challenges exist in autonomous instrument handling and solo surgical procedures.

Purpose of the Study:

  • To introduce and evaluate the Postural Mechatronic Assistant Trainer (PMAT) for pediatric Nissen surgery.
  • To assess the feasibility of solo surgery using the PMAT system.
  • To determine the benefits of the PMAT for autonomous optic management.

Main Methods:

  • Description of the PMAT system's mechatronic design and functionalities.
  • Evaluation of the PMAT in the context of pediatric Nissen surgery logistics.
