US 12,636,109 B2 · Magnetic impact needle robot

Abstract

A tetherless magnetic impact needle robot (MINRob) based on a triple-magnet system with reversible and repeatable magnetic collisions to overcome this constraint on output force. The working procedure of the system is divided into several states, and a mathematical model is developed to predict and optimize the force output. These force values in magnetic impact and penetration are obtained from a customized setup, indicating a 10-fold increase compared with existing miniature robots that only utilize magnetic attractive force. Eventually, the MINRob is integrated with a teleoperation system, enabling remote and precise control of the robot's position and orientation. The triple-magnet system offers promising locomotion patterns and penetration capacity via the notably increased force output, showing great potential in robot-assisted tissue penetration in minimally invasive healthcare.

Dependent claims

A magnetic impact robot adapted to be deployed inside a human body, the magnetic impact robot comprising an impacting portion which comprises:

a) a casing defining a first inner chamber and a second inner chamber;
b) a first permanent magnet received within the first inner chamber;
and
c) a second permanent magnet received within the second inner chamber;
wherein the impacting portion is adapted to perform a striking action along a linear direction as a result of the first permanent magnet colliding with the casing when the first permanent magnet and the second permanent magnet are actuated by a third permanent magnet that is external to the magnetic impact robot.
