Cheng Biopsy Trephine System – Large (8 mm) Trephine
Edward Cheng, MD
Cannulated T-handle and trephines allow use of a standard 1.6 mm (.062″) threaded K-wire to help facilitate grasping and removal of a core bone sample for biopsy or core decompression
- • Allows use of trephine at oblique angles to bone surface by using an anchoring K-wire and cannulated trephine
- • Avoids “skipping” of trephine teeth on bone surface
- • Facilitates optimal approach angle and direction of trephine
- • Variety of core diameters yields bone samples of sufficient size for pathology
- • Adapters allow for use of a power drill
- • Minimally invasive — soft tissue sleeve protects surrounding structures and tissue
- • Can also be used for bone graft harvesting
- • Repositioning guide allows easy adjustment of targeting K-wire
