Automating repetitive laparoscopic suturing and needle transfers to reduce surgical fatigue and procedure duration.
Using high-speed stereo cameras, the perception engine determines curved needle orientation in 6-DoF, guiding the needle driver to clamp the needle shank at the optimal 90-degree insertion angle.
A finite-state machine coordinates dual-arm circular puncture paths that minimize tissue shear strain, followed by automated looped knot tying in under 12 seconds per stitch.
In porcine bowel anastomosis trials, autonomous suturing demonstrated 100% leak-free closures under 45 mmHg bursting pressures, rivaling experienced laparoscopic surgeons in tension uniformity.
