LOCATION AND ORIENTATION ESTIMATION OF DEVICES INCORPORATING PERMANENT MAGNETS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240023823 titled 'LOCATION AND ORIENTATION ESTIMATION OF DEVICES INCORPORATING PERMANENT MAGNETS

Simplified Explanation

Methods, systems, and devices for estimating the position and orientation of invasive surgical devices relative to a reference frame are described in this patent application. The system includes permanent magnets mounted on the surgical device, magnetometer sensors at fixed locations providing a reference frame, and computational means for calculating the position and orientation of the magnets.

  • The system uses permanent magnets and magnetometer sensors to estimate the position and orientation of invasive surgical devices.
  • The permanent magnets are mounted on the surgical device, while the magnetometer sensors are fixed in a reference frame.
  • The magnetometer sensors perform magnetic field measurements of the direct current superposition field of the permanent magnets.
  • The computational means receive the input signals from the magnetometer sensors and calculate the position and orientation of the surgical device.

Potential Applications:

  • This technology can be applied to catheter guidewires, endoscopes, surgical catheters, or self-guided electrophysiology catheters.
  • It can be used in minimally invasive surgeries to accurately track the position and orientation of these surgical devices within the patient's body.
  • The system can assist surgeons in navigating and manipulating the surgical devices during procedures.

Problems Solved:

  • Accurately tracking the position and orientation of invasive surgical devices is crucial in minimally invasive surgeries.
  • This technology solves the problem of estimating the position and orientation of these devices relative to a reference frame.
  • It provides a reliable and precise method for tracking the movement of surgical devices within the patient's body.

Benefits:

  • The system improves the accuracy and precision of surgical procedures by providing real-time tracking of surgical devices.
  • It enhances the safety of minimally invasive surgeries by reducing the risk of accidental damage or incorrect placement of the surgical devices.
  • Surgeons can have better control and visualization during procedures, leading to improved patient outcomes.


Original Abstract Submitted

methods, systems and devices for estimating the position and orientation of an invasive surgical devices, for example, a catheter guidewire or endoscope, surgical catheter, or self-guided electrophysiology catheter, relative to a reference frame, are described. an example system comprises one or more permanent magnets mounted on the surgical device, a plurality of magnetometer sensors at fixed location providing a reference frame that are configured to perform magnetic field measurements of the direct current superposition field of the permanent magnets, and computational means for receiving the input signals and calculating the position and orientation of the permanent magnets mounted on the surgical device.
