Cheng Biopsy Trephine System – Handle Retaining Screw
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
