Cheng Biopsy Trephine System with Tray
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

Accuracy Statement for devices with a measuring function: Devices with a measuring function are considered non-critical, non-calibrated, and are intended for reference-only measurements. While it provides a helpful visual guide for relative measurements, it is not calibrated to specific precision standards. Measurements taken with this device should not be considered accurate enough for critical applications requiring strict dimensional tolerances. General manufacturing tolerances of +\- 1% at each graduation, or 2% of the full scale apply, but no conformance qualifications are provided or implied.
