Area of Science:

Robotics
Biomedical Engineering
Gynecological Surgery

Background:

Surgical robots with force feedback enhance precision and safety in endometrial repair.
Designing force sensors for surgical robots is difficult due to anatomical constraints and continuous rotation requirements.

Purpose of the Study:

To present a novel force-sensing surgical instrument for endometrial repair.
To enable real-time measurement of forces during robotic endometrial repair procedures.

Main Methods:

Developed a force-sensing surgical instrument comprising an inner scraping tool and an outer sheath.
Utilized the actuation force of the outer flexible sheath to predict tangential and normal forces applied to the endometrium.
Conducted experiments to validate the force sensing accuracy.

Main Results:

Simulated three operational scenarios with varying tangential force thresholds.
Quantified the mean error and standard deviation for the force sensing accuracy.

Conclusions:

The developed sensing method allows for real-time and accurate measurement of dynamic scraping forces.
This technology can enhance the safety and effectiveness of robotic endometrial repair.
