Cheng Biopsy Trephine System

The Cheng Biopsy Trephine System is a specialized orthopedic and surgical biopsy instrument set used for obtaining accurate cylindrical bone and tissue samples for histological examination, grafting analysis, and diagnostic procedures. It is commonly utilized in orthopedic oncology, spinal surgery, trauma reconstruction, and bone pathology investigations . The system includes precision trephine cutters designed to penetrate cortical and cancellous bone with controlled cutting action while preserving specimen integrity. The sharp cylindrical cutting edges allow surgeons to harvest uniform biopsy cores with minimal surrounding tissue trauma. The trephine design ensures smooth advancement into bone while reducing fragmentation of the sample, which is essential for reliable pathological analysis. The system is especially useful for procedures involving suspicious bone lesions, infection assessment, graft harvesting, and reconstructive planning. Manufactured from high-grade surgical stainless steel , the Cheng Biopsy Trephine System offers superior durability, cutting precision, and corrosion resistance under repeated sterilization cycles. The components are engineered for accurate alignment and stable rotational control during biopsy procedures. The ergonomic handles provide excellent grip and torque transmission, enabling controlled penetration through dense cortical bone. The system is fully autoclavable and reusable, making it suitable for orthopedic operating rooms, spinal surgery units, trauma centers, and pathology-focused surgical procedures.
