Vicarious Surgical Inc., a next-generation robotics technology company, has announced the successful completion of initial integrated benchtop testing for its full suite of surgical instruments required for its anticipated first clinical indication of ventral hernia repair. This milestone represents the first system-level performance evaluation of the company's three core instruments: needle drivers, fenestrated graspers, and monopolar scissors, each designed for use with the Vicarious Surgical System.

Why it matters

The successful testing of the full instrument suite is a critical step in systematically de-risking Vicarious Surgical's path toward first-in-human use of its robotic surgical system. Demonstrating reliable, integrated performance across the instruments, including stability under electrosurgical energy, reinforces the company's confidence in the system architecture and development timeline.

The details

The monopolar scissors, which previously demonstrated successful electrical performance in a December porcine lab study, exhibited strong motion and mechanical cutting capabilities following the company's standard automated calibration and bring-up process. Importantly, the instrument and camera sensors remained stable, with no degradation in video or motion quality in the presence of monopolar electrosurgical energy, confirming robust system performance under clinically relevant operating conditions.

  • The successful benchtop testing was completed on March 30, 2026.
  • In December 2025, the company's monopolar scissors demonstrated successful electrical performance in a porcine lab study.

What they’re saying

“This milestone represents an important step in systematically de-risking our system as we advance toward design freeze and first-in-human use. Demonstrating reliable, integrated performance across our full instrument suite, including stability under electrosurgical energy, reinforces our confidence in the system architecture and our development timeline. Each successful test brings us closer to enabling a new standard in minimally invasive robotic surgery.”

— Stephen From, Chief Executive Officer

What’s next

The successful completion of this benchtop testing positions the company to advance to the next phase of preclinical validation, including planned cadaveric and porcine studies, as it continues to prepare for first clinical use of the Vicarious Surgical System and execute against a defined series of development milestones leading to design freeze.

The takeaway

Vicarious Surgical's successful integrated benchtop testing of its full surgical instrument suite represents a critical milestone in systematically de-risking the company's path toward first-in-human use of its innovative robotic surgical system, bringing it closer to enabling a new standard in minimally invasive procedures.
