Highlights
● Innovative Design: A wire-driven multi-degree-of-freedom electric needle holder enhances laparoscopic suturing flexibility and stability.
● Advanced Motion Control: Two rotational joints enable yaw and pitch movements for precise needle placement in confined spaces.
● Superior Clamping Performance: With a maximum clamping force of 29.6 N an extraction force of 12.9 N, the needle holder prevents slippage.
● 28% Faster Suturing: Reduced operation time due to minimized repositioning in complex procedures.
● Clinical Potential: Validated through diverse tests, demonstrating accuracy and efficiency in minimally invasive surgery.
