SolidFlex--the fourth generation in endoscopy

Area of Science:

• Urology
• Surgical Technology
• Endoscopy

Background:

• Current endoscopic instruments include rigid, semi-rigid, and flexible ureteroscopes.
• These instruments present various challenges for surgeons, impacting procedure efficiency and patient comfort.
• A need exists for advanced endoscopic solutions that combine the benefits of existing technologies.

Purpose of the Study:

• To design and develop SolidFlex, a fourth-generation endoscopic instrument.
• To provide physicians with easier and faster solutions for endoscopic procedures.
• To overcome limitations of current rigid, semi-rigid, and flexible endoscopes.

Main Methods:

• Development of the SolidFlex endoscope, integrating state-of-the-art technology for ergonomic and intuitive use.
• The instrument offers the stability of rigid scopes with the exploration capabilities of flexible scopes.
• Designed for fluid maneuverability and precise control of the active flexible section.

Main Results:

• The SolidFlex prototype successfully retrieved urinary stones in 9 patients across 11 renal units.
• Instrument insertion to the renal pelvis took a maximum of 15 seconds post-dilatation.
• All procedures were completed, with stones ranging from 200 nm to 4 mm removed effectively.
• Patients experienced no significant pain or discomfort, requiring no analgesics.

Conclusions:

• SolidFlex technology addresses numerous challenges faced by surgeons in endoscopic surgery.
• The design allows surgeons to operate comfortably and independently, improving maneuverability and tool introduction.
• Developed by a urologist, SolidFlex offers a significant improvement over existing endoscopic technologies for physicians and patients.
