AI Technical Summary

⚠Technical Problem

Current aspiration cannulas for vitreoretinal surgery risk traumatic incarceration of retinal tissue due to accidental contact during fluid aspiration, necessitating traumatic maneuvers for removal.

⚗Method used

The aspiration cannula features a radial through-opening that allows fluid entry, reducing retinal tissue traction by equalizing pressure, thereby preventing incarceration and enabling atraumatic aspiration.

🎯Benefits of technology

The radial through-opening design minimizes tissue trauma by releasing traction, ensuring atraumatic aspiration during vitreoretinal surgery.
