Uniquely Modified Robotic-Assisted Thoracic Surgery With Good Intrathoracic Visual Field

Area of Science:

• Thoracic Surgery
• Surgical Robotics
• Oncology

Background:

• Robot-assisted thoracoscopic surgery (RATS) is increasingly utilized.
• Current RATS systems often have camera ports placed in the 8th or 9th intercostal space.
• This placement results in a restricted visual field, particularly on the cranial side.

Purpose of the Study:

• To address the limited visual field in RATS for thoracic procedures.
• To develop an improved port arrangement for enhanced surgical visualization.
• To ensure critical surgical maneuvers in lung cancer surgery can be performed safely.

Main Methods:

• A novel port arrangement, termed the "Hamamatsu method," was designed.
• This method repositions the camera port to optimize the visual field.
• The arrangement was evaluated for its effectiveness in providing a clear view during simulated thoracic procedures.

Main Results:

• The Hamamatsu method provides a significantly improved visual field on the cranial side compared to conventional port placements.
• Enhanced visualization is particularly beneficial for complex dissection near major pulmonary vessels.
• The new arrangement facilitates safer execution of critical steps in lung cancer surgery.

Conclusions:

• The Hamamatsu method offers a superior visual field for robot-assisted thoracoscopic lung cancer surgery.
• This improved visualization enhances surgical safety and precision.
• The novel port arrangement represents a significant advancement in thoracic surgical robotics.
