Medical drill system with automatic switch-off

摘要

Medical Drill System (10) with: - A drill (12) comprising a drill head (14) for receiving a drilling tool (16) and a measuring probe (20), wherein the measuring probe (20) has a transmitting unit (22) which is adapted to emit measuring signals during a drilling operation and a receiving unit (24) adapted to receive, during the drilling operation, measurement signals reflected to tissue in the vicinity of a drilling channel (26) produced by the drilling tool (16), and; - A control unit (28) which is adapted, during the drilling operation on the basis of the transmitting unit (22) of the measuring probe (20) emitted measuring signals and on the basis of the receiving unit (24) of the measuring probe (20) received reflected measuring signals identify different types of tissue in the vicinity of the drilling channel (26) produced by the drilling tool (16), wherein the transmitter unit (22) of the measuring probe (20) is adapted to receive first measuring signals in a direction substantially parallel to a drilling axis during the drilling operation ( A) and second measuring signals in a direction substantially perpendicular to the drilling axis (A), and wherein the receiving unit (24) of the measuring probe (20) is adapted during the drilling process, the reflected on tissue in the vicinity of the Bohrkanals (26) receive first and second measurement signals.
