Robot-assisted brachytherapy improves prostate cancer treatment by enhancing needle accuracy. This robotic system offers precise needle placement and seed delivery for better therapeutic outcomes.

Area of Science:

  • Robotics in Medicine
  • Medical Devices
  • Oncology

Background:

  • Accurate needle placement is critical but challenging in brachytherapy.
  • Robot-assisted systems offer potential improvements for needle and seed delivery.
  • Prostate brachytherapy requires precise targeting for effective treatment.

Purpose of the Study:

  • To develop and fabricate a novel robotic system for prostate brachytherapy.
  • To enhance needle placement accuracy and seed delivery efficiency.
  • To address challenges in target localization and instrument manipulation.

Main Methods:

  • Development of a 16-degrees of freedom (DOF) robotic system (9 DOF positioning, 7 DOF surgery).
  • Incorporation of strategies to minimize needle deflection and target movement.
