Cheng Screw Removal and Bone Trephine – 8 mm
Edward Cheng, MD
Six trephine sizes with reverse thread teeth designed to help with removal of screws with minimal bone loss, as well as gathering of core bone samples for biopsy or core decompression
Can be used with the T-handle or with power.
For Screw Removal
- • The trephine ends are designed to fit over embedded screws for extraction with minimal bone loss.
- • Six sizes available — internal diameters of 5 mm, 6.5 mm, 8 mm, 9 mm, 10 mm, and 11 mm.
- • The T-handle allows for precise, controlled use.
For Core Bone Sampling
- • 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.
- • Variety of core diameters yields bone samples of sufficient size for pathology.
- • K-wire not included.

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.
