Study of Collagen-Based Thrombin Hemostat for the Control of Bleeding in Spinal Surgery

This clinical trial evaluates the effectiveness and safety of a collagen-based hemostatic agent containing thrombin in patients undergoing spinal surgery. The study compares this investigational product with an existing hemostatic agent to assess whether it performs equally well in controlling surgical bleeding. Patients with spinal stenosis, tumors, or trauma who require spinal surgery will be enrolled. The hemostat will be applied intraoperatively when grade 3 bleeding is observed. The study aims to determine how well the product works in achieving hemostasis and its safety when it is used during surgery.
