AIMING AT IDENTIFICATION POINTS OF ORTHOPEDIC DEVICES Russian patent published in 2017 - IPC A61B17/80 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. Device for aiming at identification point of orthopedic implant comprises: case, made with possibility of engaging with mating structural element for attachment of case to orthopedic implant; and electromagnetic sensor, placed inside case of device in known position. When device case is engaged with mating structural element, position sensor relative to identification point of orthopedic implant is known in relation to five degrees of freedom. Method of aiming at identification point of orthopedic device includes following steps: location of first identification point of orthopedic device by means of identification device of identification point and first sensor of electromagnetic field, wherein identification point identification device comprises generator of electromagnetic field and first electromagnetic field sensor, when determining location of first identification point, is attached to orthopedic device and is located in zone of electromagnetic field generator, wherein location of first identification point includes movement of identification point identification device relative to orthopedic device and first sensor of electromagnetic field; attachment of second sensor of electromagnetic field to first identification point; placing of second sensor of electromagnetic field in zone of action; and location of second identification point of orthopedic device using identification point identification device and second electromagnetic field sensor using second electromagnetic field sensor attached to first identification point, wherein location of second identification point includes movement of identification point identification device relative to orthopedic device and second electromagnetic field sensor. Method of using device comprises: bringing of case to engage with mating structural element, thus attaching case to orthopedic implant; generation of electromagnetic field; movement of identification point identification device relative to orthopedic implant, thus moving electromagnetic field relative to sensor; calculation of sensor position relative to identification point identification device using signals received from sensor; and comparing calculated position of sensor relative to identification point identification device with known position of sensor relative to identification point.

EFFECT: use of given group of inventions allows excluding effect of harmful radiation on patient and/or personnel, when aiming at identification point of implant, coated with tissues.
