Development of a Navigation-guided Fence-post Catheter for Brain Tumor Resection

Area of Science:

• Neurosurgery
• Medical Device Engineering

Background:

• Navigation systems enhance brain tumor resection precision.
• Current fence-post catheter techniques often use non-specialized devices like silicone tubes or Nelaton catheters.

Purpose of the Study:

• To introduce a novel fence-post catheter with a steel tip designed for improved accuracy in tissue resection.
• To enhance tumor resection procedures in neurosurgery.

Main Methods:

• Development of a new fence-post catheter featuring a steel tip.
• The catheter is designed for visual depth gauging and is made of non-magnetic material with moderate weight.

Main Results:

• The steel tip provides a clear indicator as operators approach the tumor base during resection.
• Facilitates accurate depth perception, particularly for deep-seated tumors.

Conclusions:

• The newly developed fence-post catheter simplifies distance confirmation to deep-tissue regions.
• Enhances the overall safety of tumor removal procedures.
