This visual intervertebral reamer features a T-shaped dual-handle design with thickened anti-slip grips on both ends, delivering balanced and labor-saving force during rotational grinding to reduce arm fatigue over long procedures. Clear depth markings run along the entire shaft, allowing surgeons to directly observe and control reaming depth; combined with dual-channel endoscopy for visualized operation, it prevents excessive grinding damage to vertebral endplates. The slotted reamer tip provides smooth cutting, efficiently removing hyperplastic tissue in intervertebral spaces and trimming endplates. The slots discharge bone debris simultaneously without blocking the surgical view. Constructed from high-strength stainless steel, it resists bending under grinding pressure and supports repeated high-temperature sterilization.
