“I had a great experience using the Krystolens neuroendoscope. Having an all-in-one set means I don’t need extra surgical instrument preparation. The visual quality is clear, and it has enough working channel to comfortably operate the surgical instruments.”
– Dr. Chen Chih-Hsiu, Neurosurgeon at Chung Shan Medical University Hospital
Brain Navi had the pleasure to have neurosurgeon Dr. Chen Chih-Hsiu, try using our Krystolens neuroendoscope to perform fenestration at the brain’s third ventricle.
Currently practicing at Chung Shan Medical University Hospital, Dr. Chen earned his medical degree from China Medical University and his Master’s degree from Chung Shan Medical University.
In the past, even for minor neurosurgery procedures patients had no choice but to undergo a craniotomy.
Today, thanks to the neuroendoscope invention, it enables neurosurgeons to perform minimally invasive procedures, significantly shortening patient’s post-surgery recovery times.
However despite these advances, the current commonly used neuroendoscope setups still have a few issues:
1. Separate Instruments
Standard protective tube neuroendoscope systems lack built-in optics. Surgeons must manually source, align, and insert an external endoscope lens into the casing.
2. Sterilization Burden
Reusable endoscopes and individual components require extensive pre- and post-operative cleaning, autoclave scheduling, and strict reprocessing checks.
3. Complex Preparation
Surgical and nursing teams must manage multiple preparation steps, gathering separate items before a procedure can even begin.
Hence, Brain Navi has developed the Krystolens neuroendoscope to directly solve these issues.
Clinical Feedback from Dr. Chen Chih-Hsiu
During a recent interview session, Dr. Chen highlighted several features that set Krystolens apart from the traditional neuroendoscope he normally uses:
1. All-in-One Integration
By making the working channel and optics into an all-in-one system, Krystolens eliminates the extra step of preparing standalone components.
2. Optical & Spatial Quality
Krystolens managed to provide sharp visual clarity while leaving sufficient working space and depth to comfortably operate surgical instruments.
3. Surgical Versatility
Dr. Chen successfully used the system for delicate procedures at the floor of the third ventricle, showing its reach beyond standard indications.

Krystolens Other Benefits
1. Elevated Sterile Safety
As a single-use neuroendoscope system, Krystolens eliminates the risks of cross-contamination associated with reusable equipment and removes the complex, time-consuming sterilization procedures required between cases.
2. Cost-Effective Efficiency
For hospitals or surgical departments managing lower procedure volumes, Krystolens provides a practical financial alternative.
Being single-use avoids the heavy capital investment, ongoing maintenance costs, typical of traditional re-sterilizable endoscopy equipment.
The Future of Neuroendoscopy
By addressing the inefficiencies of traditional multi-piece systems, integrated neuroendoscopic solutions save critical setup time, improve precision, and minimize contamination risk.
Brain Navi is looking forward to seeing more neurosurgeons try using Krystolens and discover just how convenient and life-changing it can be in the operating room.
