Large-Field-of-View Visualization Utilizing Multiple Miniaturized Cameras for Laparoscopic Surgery.

Area of Science:

• Minimally Invasive Surgery
• Surgical Technology
• Medical Imaging

Background:

• Intra-abdominal visualization is crucial for laparoscopic procedures.
• Current single laparoscope use offers a restricted field of view (FoV), limiting surgical efficiency and scope.
• The need for improved visualization in laparoscopy is well-established.

Purpose of the Study:

• To introduce a new trocar-camera assembly (TCA) designed to significantly increase the FoV in laparoscopic surgery.
• To evaluate the TCA's potential for enhancing surgical efficiency and expanding the range of achievable operations.
• To demonstrate the feasibility of real-time video stitching for creating a panoramic view.

Main Methods:

• Development of a trocar-camera assembly (TCA) integrating multiple miniature cameras.
• Implementation of a video stitching program to combine camera feeds in real-time.
• Testing the TCA in a simulator box using standard and modified bean drop tasks to assess performance and FoV.

Main Results:

• The TCA successfully provided a significantly larger FoV compared to conventional laparoscopic cameras.
• Video stitching enabled distortion-free, real-time panoramic visualization on an operating monitor.
• Demonstrated improved efficiency and expanded operational range in simulated surgical tasks.

Conclusions:

• The developed trocar-camera assembly (TCA) offers a substantial improvement in intra-abdominal visualization for laparoscopic surgery.
• The TCA enhances surgical efficiency and broadens the scope of operations by providing an expanded, real-time view.
• This technology has the potential to free up surgical ports and reduce reliance on camera-operating assistants.
