AI Technical Summary
In existing technologies, when interventional surgical robots detect the stress on slender medical devices such as guidewires or catheters using pressure sensors, the detection accuracy is easily affected by the vibration and acceleration/deceleration forces of the drive device, leading to inaccurate detection.
The device employs a combined structure of a delivery component, a drive component, and a torque sensor. The torque sensor is connected to both the drive component and the delivery component. It detects the stress on slender medical devices by detecting changes in the torque of the delivery component. The dynamic torque sensor avoids the influence of acceleration/deceleration forces and vibrations of the drive device on the detection.
It improves the accuracy of delivery force detection for slender medical devices, reduces the impact of drive device vibration and acceleration/deceleration forces on detection, and ensures the stability and accuracy of detection.
