Design of the computerized 3D endoscopic imaging system for delicate endoscopic surgery

Area of Science:

• Medical Technology
• Surgical Innovation
• Endoscopic Imaging

Background:

• Traditional 2D endoscopy limits depth perception and surgical dexterity.
• Improving visualization is crucial for enhancing surgeon performance in minimally invasive procedures.

Purpose of the Study:

• To evaluate a novel 3D endoscopic video system for improved surgical visualization.
• To compare the performance of polarized 3D versus conventional stereo imaging systems in simulated surgical tasks.

Main Methods:

• Development of a 3D endoscopic video system with a wide viewing angle.
• Comparative analysis of polarized and conventional electric shutter-type stereo imaging systems.
• Assessment of surgical task performance (suturing, loop pass test) in 2D and 3D modes.

Main Results:

• The polarized 3D system demonstrated superior accuracy and speed in suturing and loop pass tests compared to conventional systems.
• No significant difference in task performance between 2D and 3D modes for loop passing and suturing.
• Suturing task completion time was reduced by 15% (p < 0.05) in 3D mode.

Conclusions:

• The proposed 3D endoscopic system offers enhanced visualization capabilities for complex surgical procedures.
• Polarized 3D imaging technology shows promise for improving surgical outcomes in endoscopy.
• The system's wide viewing angle and multi-viewing zone support advanced endoscopic surgery.
