Zusammenfassung:Devices and methods used to obtain core tissue samples are disclosed. The devices may be configured to drill into cortical bone and saw a hole into a bone lesion and/or bone marrow while obtaining the core tissue sample. The devices can include a motor and a clutch configured to rotate a trocar having a tip configured for drilling and an outer coax cannula having a trephine tip configured for sawing. The core tissue sample may be received within an inner cannula as an intermediate cannula cuts a hole in the bone lesion and/or bone marrow. The devices can include a spacer.
