INSERTION APPARATUS FOR AN INVASIVE PROCEDURE AND METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240032962 titled 'INSERTION APPARATUS FOR AN INVASIVE PROCEDURE AND METHOD

Simplified Explanation

The patent application describes systems and methods for improving the positioning and alignment of a needle-shaped instrument during an MR image-guided invasive procedure. The invention includes an insertion apparatus with a pen-shaped main body that has a longitudinal axis. The main body also has a guidance facility for guiding a predefined needle-shaped instrument parallel to the longitudinal axis. Additionally, a 3D magnetic field sensor is provided in the main body to measure magnetic field values in three orthogonal spatial directions. These magnetic field values are conveyed to an external analysis facility through a signal interface.

  • The invention is an insertion apparatus designed to facilitate the positioning and alignment of a needle-shaped instrument during MR image-guided invasive procedures.
  • The apparatus has a pen-shaped main body with a longitudinal axis, providing a familiar and ergonomic design for ease of use.
  • A guidance facility is incorporated into the main body to guide the needle-shaped instrument parallel to the longitudinal axis, ensuring accurate placement.
  • The main body includes a 3D magnetic field sensor that measures magnetic field values in three orthogonal spatial directions, providing precise spatial information.
  • The magnetic field values are transmitted to an external analysis facility through a signal interface, allowing for real-time monitoring and analysis.

Potential applications of this technology:

  • Medical procedures: The invention can be used in various MR image-guided invasive procedures, such as biopsies, injections, and catheter insertions, to improve accuracy and reduce the risk of complications.
  • Research and development: The apparatus can be utilized in research settings to study the effects of needle placement and alignment on procedure outcomes, leading to advancements in medical techniques and technologies.

Problems solved by this technology:

  • Difficult needle positioning: The invention addresses the challenge of accurately positioning and aligning a needle-shaped instrument during MR image-guided procedures, reducing the risk of damage to surrounding tissues and improving overall procedure outcomes.
  • Limited spatial information: The 3D magnetic field sensor provides precise spatial information, allowing for better visualization and control of the needle's position within the body.

Benefits of this technology:

  • Improved accuracy: The guidance facility and magnetic field sensor work together to ensure precise needle placement, reducing the need for corrective actions and improving the overall accuracy of the procedure.
  • Enhanced safety: By minimizing the risk of damage to surrounding tissues, the invention enhances patient safety during MR image-guided invasive procedures.
  • Real-time monitoring: The ability to transmit magnetic field values to an external analysis facility in real-time allows for continuous monitoring and adjustment during the procedure, further improving accuracy and safety.


Original Abstract Submitted

systems and methods for positioning and/or aligning a needle-shaped instrument more easily during an mr image-guided invasive procedure. an insertion apparatus is provided having a pen-shaped main body that has a longitudinal axis. in addition, the insertion apparatus has a guidance facility in or on the main body for guiding the predefined needle-shaped instrument parallel to the longitudinal axis of the main body. in the main body is provided a 3d magnetic field sensor for measuring magnetic field values with respect to three orthogonal spatial directions. a signal interface is used to convey the magnetic field values to an analysis facility external to the insertion apparatus.
