Smart tissue anastomosis robot (STAR): a vision-guided robotics system for laparoscopic suturing

Area of Science:

• Robotics in Surgery
• Minimally Invasive Procedures
• Surgical Technology

Background:

• Laparoscopic surgery requires precise suturing techniques.
• Current robotic and manual methods have limitations in speed and consistency.
• Advancements in robotic systems are crucial for improving surgical outcomes.

Purpose of the Study:

• To introduce the Smart Tissue Anastomosis Robot (STAR), a proof-of-concept vision-guided robotic system.
• To evaluate the performance of the STAR system in executing running sutures.
• To compare the STAR system's efficiency and accuracy against existing surgical methods.

Main Methods:

• Development of a vision-guided robotic system (STAR) with an actuated laparoscopic suturing tool.
• Integration of a custom motor stage and supervisory control architecture.
• Implementation of manual and automatic suturing modes based on image-based commands and incision contours.

Main Results:

• The STAR system demonstrated superior accuracy and consistency in experiments on planar phantoms.
• The STAR system was up to five times faster than surgeons using state-of-the-art robotic systems.
• The STAR system was four times faster than manual Endo360(°)® and nine times faster than manual laparoscopic tools.

Conclusions:

• The STAR system represents a significant advancement in robotic-assisted laparoscopic surgery.
• The vision-guided system offers enhanced speed, accuracy, and consistency for tissue anastomosis.
• Further development of the STAR system holds potential for improving surgical efficiency and patient outcomes.
