A robot for catheter operation with force measurement

Abstract

Herein disclosed is a robot apparatus having two or more robot units, each robot unit is configured to maneuver on an intracavity surgical device, such as a catheter, a guide wire, or tools for laser ablation. Also included is a reciprocating conveyor having a motion converter, such as a scotch yoke, coupled with a rail slider to produce linear reciprocating movements to bring the robot units back and forth from and towards a patient. A load measuring device is also included to sense both the axial force and the torque exerted on the surgical device and based on the real time load measurement, to control the scotch yoke and the robot unit more accurately for inserting the intracavity surgical device into or withdrawing it from the surgical subject.

Dependencies are inferred from the claim text.
