Micro- and macro-borderless surgery using a newly developed high-resolution (4K) three-dimensional video system

Area of Science:

• Minimally Invasive Surgery
• Surgical Technology
• Medical Imaging

Background:

• Conventional microsurgery with microscopes or loupes has limitations in field of view and surgeon ergonomics.
• These limitations can lead to surgeon strain, particularly during extended surgical procedures.

Purpose of the Study:

• To evaluate the applicability and efficacy of micro- and macro-borderless surgery (MMBS) using a novel 4K 3D video system.
• To assess the system's performance in various complex surgical scenarios.

Main Methods:

• Non-inferiority testing of MMBS versus surgical loupes in porcine models for procedures like carotid artery dissection and pancreatoduodenectomy.
• Feasibility testing of MMBS for anastomosing small intra-abdominal and intra-thoracic arteries.
• Application of MMBS in orthotopic liver transplantation from a machine-perfused donor after circulatory death.

Main Results:

• All surgical procedures were successfully completed using the MMBS system.
• The system provided a shared, heads-up field of view for the surgical team.
• Sufficient focal depth and the ability to evaluate tissue circulation via fluorescence imaging were demonstrated.

Conclusions:

• MMBS utilizing the novel 4K 3D video system is applicable to a wide range of surgical procedures.
• The technology offers significant value for both intricate surgical interventions and advanced surgical training.
