NYU Abu Dhabi Researchers Create Sensing System To Enhance Tactile Feedback In Laparoscopic Surgeries

Researchers at NYU Abu Dhabi's Advanced Microfluidics and Microdevices Laboratory (AMMLab) have created a sensing system that restores tactile feedback in minimally invasive surgery (MIS). This system enhances precision, usability, and safety by integrating force and angle sensors into laparoscopic tool handles. Surgeons receive real-time data on grasping forces and tissue characteristics, improving surgical outcomes.

Minimally invasive surgery involves small incisions, which reduce pain, recovery time, and infection risk. However, traditional MIS tools lack tactile feedback, making it hard for surgeons to gauge the correct force or differentiate tissue types. This absence of touch can lead to errors like over- or under-grasping delicate tissues.

The "off-the-jaw" design by AMMLab researchers is a notable shift from previous methods that placed sensors at the tool's jaws. This new approach is detailed in IEEE Access. It not only improves surgical accuracy but also offers objective tactile feedback, helping new surgeons quickly master MIS techniques.

This technology's adaptability allows it to be used in robotic-assisted surgery, endoscopy, telemedicine, and other medical fields. Its scalability ensures broad application potential across various surgical procedures.

"Minimally invasive surgery has revolutionised the field, but the lack of tactile feedback remains a challenge," stated Mohammad A. Qasaimeh, Associate Professor of Mechanical Engineering and Bioengineering at NYU Abu Dhabi. The new system addresses this issue effectively.

Wael Othman, Ph.D., Postdoctoral Researcher at AMMLab, noted that early trials showed a 30 percent improvement in surgical task efficiency. This highlights the practical benefits of this technology on surgical performance.

The introduction of this sensing system could significantly shorten the learning curve for new surgeons by providing essential tactile information during procedures. This advancement accelerates their proficiency in MIS techniques.

This innovative development marks a significant step forward in enhancing the safety and effectiveness of minimally invasive surgeries. By restoring tactile feedback, it addresses a critical gap in current surgical practices.
