Claims12
A positioning device for positioning a medical instrument relative to a patient comprising:
- a patient fastening member configured to fasten the positioning device to the patient and including a patient holding surface for bearing on the patient, and
- an instrument holder including a rotary mechanism and a displacement mechanism, wherein the instrument holder is configured to:
- hold the medical instrument,
- connect to the patient fastening member via the rotary mechanism, such that the instrument holder is mounted in an axis orthogonal to the patient holding surface so as to be rotatable relative to the patient fastening member, and
- couple to the patient fastening member via the displacement mechanism such that:
- the instrument holder is displaceable in several directions in a plane parallel to the patient holding surface or in a spherically or cylindrically curved path, and
- the rotary mechanism is displaceable via the displacement mechanism in several directions.
