This research introduces a robotic vision framework to enhance laparoscopic surgery by intelligently guiding the surgical scope. This system improves surgeon control, patient safety, and operational efficiency during minimally invasive procedures.

Area of Science:

  • Robotics
  • Computer Vision
  • Surgical Technology

Background:

  • Minimally invasive surgery, particularly laparoscopy, benefits from advanced vision and robotics.
  • Current laparoscopic procedures can be limited by manual scope control and potential risks.
  • Integrating intelligent systems can enhance surgical precision and safety.

Purpose of the Study:

  • To propose a novel framework integrating vision and robotics for enhanced laparoscopic surgery.
  • To assist surgeons in maneuvering the surgical scope (camera) with intelligent visual modeling and recognition.
  • To improve patient safety and procedural efficiency through automated scope control.

Main Methods:

  • A framework combining top-down anatomical modeling with bottom-up image analysis.
