Title:
コンピュータ支援整形外科手術システムを用いて患者の骨を登録する装置および方法
Document Type and Number:
Japanese Patent JP4884960
Kind Code:
B2
Abstract:
Apparatus for registering a bone of a patient with a computer assisted surgery system (Fig. 35) includes a support frame (602) and a number of magnetic sensor arrays (604,606) movably coupled to the support frame. Each of the magnetic sensor arrays may be pivoted and translated with respect to the frame. In addition, each of the magnetic sensor arrays may include a circuit (650) for sensing a magnetic field generated by a magnetic source coupled to the bone of the patient. Each circuit may include one or more magnetic sensors, a processing circuit, an angle sensor (662), a distance sensor (666), and a transmitter. The magnetic sensors and processing circuit cooperate to determine a position of the magnetic source. The angle sensor, distance sensor, and processing circuit cooperate to determine a displacement of the magnetic sensor array from a reference point. The processing circuit controls the transmitter to transmit data indicative of the position of the magnetic source.
