Patent ID: 8317682

Claim:
A medical device control system comprising: a medical device including: an insertion member configured to be inserted into a subject's body, and a magnetic field response portion, operatively connected to the insertion member, for generating torque in response to a magnetic field applied from outside the subject's body; a magnetic field generation portion for generating the magnetic field for directing the insertion member to a control direction; a direction detection unit for detecting an insertion direction of the insertion member; a user interface for receiving an input by an operator; a magnetic field pattern storage portion for storing in advance a plurality of magnetic field patterns to be generated by the magnetic field generation portion; and a magnetic field control unit for: determining the control direction of the insertion member based on the insertion direction detected by the direction detection unit and the input received by the user interface, selecting a magnetic field pattern from the plurality of magnetic field patterns stored in advance in the magnetic field storage portion based on a discordance between the insertion direction and the control direction, and controlling the magnetic field generation portion in accordance with the control direction and the selected magnetic field pattern.
