A new curved multi-tube device (CMTD) system precisely corrects needle insertion path errors. Computerized guidance accurately steers the CMTD using ultrasound imaging for improved diagnostic and therapeutic procedures.

Area of Science:

  • Medical Devices
  • Robotics in Medicine
  • Image-Guided Therapy

Background:

  • Needle insertion is crucial for disease diagnosis and treatment.
  • Existing methods face challenges in precision and path correction.
  • A novel Curved Multi-Tube Device (CMTD) system is introduced.

Purpose of the Study:

  • To describe a prototype CMTD system for computerized path-error correction during needle insertion.
  • To evaluate the system's efficacy in a controlled environment.

Main Methods:

  • The CMTD system features straight-needle and curved-needle modes.
  • A prototype system was tested using a water phantom.
  • Ultrasound imaging was employed for real-time guidance and error correction.

Main Results:

  • Needle insertion was accurately centered within the ultrasound image.
  • The CMTD successfully extended its inner needle to correct insertion path errors.
  • The system demonstrated precise control over needle trajectory.

Conclusions:

  • The CMTD system effectively corrects needle insertion path errors.
  • Computer processing accurately determines needle path from ultrasound images.
  • The system automatically guides the CMTD to the target, enhancing procedural accuracy.
